Abstract

PURPOSE:To perform the binding operation of the sheets received in a plurality of sheet receiving means by one binding means by providing a means binding exposed manuscripts at a position other than the arranging place of the receiving means. CONSTITUTION:Transfer sheet 37 is copied in an image forming part 6 to be fed to a finisher 11 and the processing of the transfer paper 37 and manuscripts 69 is carried out by a bin movable type sorter-stapler. The stapler 65 is supported by a pair of lead screws 423 so as to freely approach and separate with respect to the side surfaces of sheet receiving bins 57. The lead screw 423 is rotationally driven by a stapler moving motor 427 through a gear group 425 and the stapler 65 is subjected to approach and separating operation (arrow M33 direction) by this rotation. At the time of non-stapling, the stapler 65 is retracted from a stapling notch by the driving of the stapler moving motor 427 and, at the time of stapling, the stapler 65 advances into the stapling notch.

Description

[Detailed description of the invention]

[Industrial Application Field] The present invention relates to a sheet processing apparatus that is connected to an image forming apparatus such as a copying machine, a facsimile machine, or a printer, and performs sorting and paper binding of sheets including exposed originals and image-formed recording paper. [Prior Art] Sorters and stackers using bins are generally known as sheet processing apparatuses. These sorters and stackers are installed, for example, on the downstream side of the fuser of a copying machine in the sheet conveyance direction, and stack sheets on which images have been formed in page order or in units of the same page, depending on the sort mode or suit tough mode. It has become. Recently, binding devices equipped with so-called staplers, which automatically staple the sheets stacked in these bins after sorting or stacking them, have also come on the market. These devices are also commonly referred to as sorter staplers. This sorter/stapler has, for example, a system that: ■ sorts sheets using bins arranged in multiple stages as sheet storage means, and staples the sorted sheets using a stapler provided movably relative to the bins; ■ Bins arranged in multiple stages are used to sort sheets, the sorted sheet groups are gripped by sheet gripping means, and the sheets are moved from above the bins to the binding position for binding. (Japanese Patent Laid-Open No. 6O-1584)
65), ■ Sorting sheets using bins arranged in multiple stages,
Move the sorted sheet group to the stable tray,
There are known devices in which the stabilized sheets are dropped onto a stacker after being stapled on a stable tray. On the other hand, in an image forming apparatus, especially an image forming apparatus ζ configured to form an image based on some kind of document, it is necessary to automatically feed and process the document in order to increase production efficiency. be. In particular, in recent years, various functions have been required for handling documents, and document feeding devices themselves have become more complex. For this reason, there are now document placement tables formed in multiple stages, so-called multi-stage document trays. This type of device uses a spiral cam to move multiple document trays to a document feeding device as disclosed in Japanese Patent Application Laid-open No. 61252564, and Japanese Patent Application Laid-Open No. 63-82249.
As disclosed in the above publication, the original 1-ray group is moved to the original feeding position using the ri-and-binion, and the original is guided to the feeding position using the tilt of the original tray and the stopper. The configuration is known. [Problem to be Solved by the Invention] However, as mentioned above, various techniques have been developed and implemented for post-processing sheets on which images have been formed, in this case image-formed recording paper, but the exposure method Or, no technology has been implemented that takes into account the processing of the already read original. Therefore, no matter how many document trays are used on the document feeding side, productivity in image processing does not improve. The present invention has been made in view of the actual state of the prior art as described above, and an object thereof is to provide a sorting device that takes post-processing of documents into consideration and is capable of performing image forming processing with high productivity. [Means for Solving the Problems] The above object is achieved by providing a binding means for binding exposure method originals at a location other than the location where the storage means is installed in a sheet processing apparatus having a storage means for storing exposure method originals. achieved. In this case, the storage means may be provided with a feeding path for feeding the image-formed recording paper, so that not only the exposure method original but also the image-formed recording paper can be stored therein. Furthermore, by accommodating the image-formed recording paper in this way, it is preferable that the binding means be provided so that it can bind both the exposure method original and the image-formed recording paper. [Function] In the above means, by providing the binding means outside the storage means, it is possible to bind sheets stored in a plurality of sheet storage means using only one binding means. In other words, if the binding means is arranged inside the sheet means, the sheets stored in each storage means cannot be bound unless each storage means is provided with a binding means, but by doing so, the binding operation can be performed in a small size. becomes possible. Furthermore, by providing the storage means with a feeding path for feeding the image-formed recording paper, it becomes possible to feed and store not only the exposure method original but also the image-formed recording paper into the storage means. Therefore, it becomes possible to bind both the exposure method original and the image-formed recording paper using the binding means, and it becomes possible to store and bind the exposure method original and the image-formed recording paper with one binding means. . In addition, in this specification, explanations related to the above-mentioned means and effects according to the present invention are mainly explained below.

I will only explain about.

[2. [Document Conveyance System Unit] First, as for the order of copying, since copying cannot be performed unless the document is cented, we will start by explaining the processing mechanism for the document to be copied. (2,1 Multistage ADF) FIG. 2 is an enlarged view of the main parts of the document transport system section 9. This document conveying system unit, that is, the multi-stage ADF 49 has five stages of original document bins 2 each configured as an independent unino 1.
01a, 201b, 201c, 201d, 201e
(Hereinafter, when referring to the document bin generally, reference numeral 201 will be used).
It consists of a document transport unit T-51 also shown in the detailed view of FIG. As shown in the main part plan view of FIG. 3 and the explanatory diagram showing the structure and operation of FIG. Stoppers 203a, 203b, 203c, 203d, 2, which also function as actuated members, are formed at the downstream end of each document bin 201 in the document transport direction.
03e (Hereinafter, when the stopper is generally shown,
a Geneva wheel 207 that engages with any one of the document bins 201 (reference numeral 203) to move any of the document bins 201 to the document feeding position; and a document 69 placed on the document bin 201 during document feeding. It mainly consists of a bottom plate 211 that pushes up the document 69 toward the calling roller 209, a separation roller 215 provided along the conveyance path 213, and a pull-out (registration) roller 217 that defines the conveyance timing of the leading edge of the document 69. The document bin 201 has upper and lower bin guide paths 220 and 221 that are provided substantially perpendicularly partially opposite to the rotation locus of a notch 219 formed in the Geneva wheel 207.
The stopper 203 is set to engage and guide the Geneva wheel 2 along the lower bin guide path 221.
A bin switching pawl 223 is provided on the center side of the document bin 201 for separating each document bin 201 from the Geneva wheel 207 and guiding it to the lower bin guide path 221. A bottom plate lifting hole 225 is formed at a position adjacent to the stopper 203 of each document bin 201 so that the bottom plate 211 can push up the document 69 placed on the document bin 201. Further, at the lowest part of the lower bottle guide path 221, there is a push-up member 22 for constantly elastically urging the stopper 203 located in the bottle guide path 221 upward by a tension spring 227.
9 is installed. The Geneva wheel 207 is rotated in forward and reverse directions by a wheel motor 231 consisting of a stepping motor. The pick-up roller 209 and the separation roller 215 are rotationally driven by a transport motor 233 via a pick-up roller drive bell) 210 and a separation roller drive belt 216, respectively, and the driving force of the transport motor 233 is transmitted to the pull-out roller 217 via a gear 235. The signal is transmitted to a registration clutch 237 that performs drive control. This resist clutch 2
37 is driven by a resist solenoid 238. Furthermore, further below the lower bottle guide path 221,
Bin switching solenoid 240 that drives the bin switching claw 223
is installed. The bottom plate 211 is swing-driven by a bottom plate drive arm 239, which is driven by a bottom plate drive motor 24 that can rotate in forward and reverse directions.
1. Moreover, along the conveyance route 213,
a leading edge detection sensor 243 that detects the leading edge position of the document 69;
A registration detection sensor 245 for detecting the registration state of the original 69 is provided, and is located at a position along the upper bin guide path 220 and at a position corresponding to the upper surface of the original bin 201 when it enters the paper feed port 247 side. A document cent detection sensor 249 is provided to detect whether the document bin 201 is set. A bottom plate home position sensor 251 is disposed below the bottom plate 211 to detect the home position of the document bin 201 that has been evacuated from the bottom plate lifting hole 225. Standby home position sensor 25 for detecting home position
7 and a paper feed home position sensor 259 are provided at positions facing the Geneva wheel 207. Each of these mechanisms connects to the document bin 2 via guide paths 220 and 221.
It is housed in a side plate 261 that supports 01. FIGS. 4(b) and 4(C) are explanatory diagrams illustrating the raising and lowering operation of the document bin 201 and the movement operation to the document feeding position. The document bin 201 group is in the initial position as shown in FIG.
As shown in the figure, the five-stage document bins 201a to 201e and the dummy bin (corresponding to the push-up member 229) are located below the Geneva wheel 207, and are always kept upward by a tension spring 227 that elastically biases the push-up member 229. energized to 1
The document bin 201a in the third stage is in pressure contact with the outer periphery of the Geneva wheel 207. In addition, the bin switching claw 2
23 is in a downward position. When the wheel motor 231 rotates counterclockwise in the figure from this state, the Geneva wheel 207 is rotated in the same (counterclockwise) direction by the wheel motor 231.Then, the notch 219 provided in the Geneva wheel 207 is When the stopper 203a comes to a position facing the stopper 203a, the elastic force of the tension spring 227 causes the stopper 203a to
fits into the notch 219. During this time Geneva Wheel 20
7 continues to rotate, the document bin 201a remains in the notch 21 as the Geneva wheel 207 rotates.
It rises along a 90 rotation trajectory. When the document bin 201C comes to the paper feed home position sensor position due to this rise, the paper feed home position sensor 259 detects this. This detection output stops the wheel motor 231 (this position is the A4 position in FIG. 4('b) showing the operation of the third-stage document bin 201C), and this time it rotates in the opposite direction, that is, clockwise. . Along with this rotation, the Geneva wheel 207 also rotates clockwise, and the document bin 207 also rotates clockwise.
With the stopper 203a of 01a engaged, the document bin 201a is advanced in one direction of the document feeding position. During this rotation process, the stopper 203a engaged with the notch 219 moves to the B4 position without separating from the notch 219 when the stopper 203a comes to a position facing the lower bottle guide path 221. The stopper 203b of the second-stage document bin 201b waits at the opening of the lower bin guide path 221 while being elastically biased upward, and the bin guide path 221 is closed by the next-stage bin. This is because that. When the document bin 201a is advanced toward the document feeding position in this manner, the document set detection sensor 249 detects the document center position, that is, the document feeding position, and stops the wheel motor 231 (this position (This is position B4 in FIG. 4(b) showing the operation of the first original document bin 201C). This means that the document bin 201a is set at the document feeding position. In this way, the document bin 201a
is set at the document feeding position, the bottom plate lift motor 241 starts rotating as described later, moves the bottom plate 211 upward, presses the document 69 against the calling roller 209, and lifts the document 69.
9 feeding becomes possible. When the zipping of the first document bin 201a is completed in this manner, the document bin for the next job is selected according to the mode input in advance. Therefore, it is necessary to save the document bin 201a after the job has been completed. This retracting operation is performed by rotating the wheel motor 231 counterclockwise from the document feeding position f (position B). That is, when the wheel motor 231 rotates counterclockwise, the Geneva wheel 207 also rotates in the same direction, and in conjunction with this rotation, the stopper 203a of the document bin 201a is moved in the same direction. As a result, when returning to the A3 position, the upper bottle guide path 220 is now open, and when the stopper 203a engages with the opening, the Geneva wheel 20
It separates from the notch 219 of 7. Then, by rotating counterclockwise, a notch 219 is formed at a position 1 opposite to the stopper 203b of the document bin 201b located at the upper end of the lower bin guide path 220 (then, the stopper 203b is inserted into the notch 219 The document bin 201b is inserted and engaged, and the same operation sends the document bin 201b to the document feeding position or the upper bin guide path 220. When returning the 201 to the lower bottle guide path 221, the wheel motor 231 is rotated clockwise and the Geneva wheel 207 is rotated in the same direction.
When the document bin 201 is in a position opposite to the opening of the
The stopper 203 falls into the notch 219 due to its weight and engages therein. On the other hand, the bin switching pawl 223, which had been retracted from the rotation locus of the Geneva wheel 207, is raised by a driving means (not shown) to the point where it interrupts the rotation locus of the notch 219, as shown in FIG. 4 ic). As a result, when the stopper 203, which has descended while rotating clockwise while engaged with the 7 pawl 203, comes to a position facing the opening of the lower bottle guide path 221, this bin switching pawl 223 It will come into contact with. Due to this contact, the stopper 203 is pressed against the abutment surface of the bin switching pawl 223, and further moves downward along the lower bin guide path 221 against the elastic biasing force of the tension spring 227, causing the stopper 203 to switch Leave the gap 219. When the Geneva wheel 207 is detached in this way, the outer peripheral surface of the Geneva wheel 207 comes into contact with the stopper 203, so that the stopper 203 is connected to the lower bottle guide path 222.
There will be no departure from. This state is the state shown in FIG. 4(C). FIG. 5 is a schematic explanatory diagram showing a mechanism for raising the bottom plate. In the figure, three bottom plates 211 are provided for the bottom plate lift arm 229, and are advanced from below the document bin 201 onto the document bin 201 by a bottom plate lift motor 241 to press the document 69 against the calling roller 209 side. When the document bin 201 is set at the paper feeding position, the bottom plate lifting motor 241 starts rotating, and the bottom plate 211 rises. The original 69 lifted by the bottom plate lifting motor 241 is
It comes into contact with the calling roller 209, and in this state, the calling roller 209 is slightly lifted. Then, the rise detection shielding plate 265 releases the shielding state of the rise detection sensor 263 (

, the original 69 is raised. The rotation speed of the bottom plate lifting motor 241 is determined by two gears.
The speed is reduced to about 1/10. This is the bottom plate lift motor 24
This is to increase the torque of 1 through the gear and to slowly lift the original 69 to improve the detection accuracy of the upper limit detection sensor 263. Furthermore, a worm gear is used as the first stage gear of the bottom plate lift motor 241, and this is to prevent a force in the reverse direction from acting on the sector gear 235 due to the weight of the documents in the document bin 201. 6 is a schematic explanatory diagram showing the relationship between the pick-up roller 209 and the separation roller 215, FIG. 7 is a schematic configuration diagram showing the structure in the vicinity of the pull-out roller 217, and FIG.

After inserting the original 69, when the print key 663 of the copying machine 1 is pressed, the call solenoid 267 is turned on. When the calling solenoid 267 is turned on, the plunger is pulled, the operating shaft 269 and the assembly 271 of the operating lever 270 fixed to the operating shaft 269 rotate in the direction of arrow C, and the calling roller 209 descends to remove the document 69. 0 that adheres to
Next, the conveyance motor 233 is turned on, and the signal is transmitted to the separation roller 215 via the separation roller drive belt 216, so that the separation roller 215 rotates. This rotational driving force is transmitted to the calling roller 209 via the calling roller drive belt 210, the calling roller 209 rotates, and the document 69 is fed. In addition, the registration solenoid 238 is connected to the transport motor 233O.
Since it turns on at the same time as N, the driving force of the transport motor 233 is transmitted to the registration clutch 237, and further
The pull-out roller 217 rotates, and the document 6
9 is sent to the document transport unit 51. The registration clutch 237 uses a spring clutch, and when the original 69 is sent to the original transport unit 51 and the registration detection sensor 245 is turned OFF, the registration solenoid 23 is activated.

7 stops, the pullout roller 217 also stops,
Feeding of the original 69 is stopped. Note that in the automatic document feed mode (ADF mode), the call solenoid 267 goes to 0FFL when the leading edge detection sensor 243 is turned ON by the document 69, and in the semi-automatic document feed mode (SADF mode), the registration detection sensor 245 is turned ON. This turns the calling solenoid OFF. The separation roller 215 separates the document 69, and as shown in the side view of FIG. 9 Tal and the front view of FIG. 215) are formed alternately in the circumferential direction, and the stepped portions are formed so as to bite into the different steps.As a result, the original 6
9 are separated by frictional force to improve document conveyance and prevent double feeding. In order to improve the conveyance of the document 69, the separation roller 215 is operated by an operating lever provided at one end of the support shaft 273 of the lower separation roller 215b when the document 69 faces the separation roller 215, as shown in FIG. The lower separating roller 2 rotates in the feeding direction by the rotation of 275 to securely hold the document 69.
15b, while the conveyance motor 233 is turned on in order to prevent wear of the separation roller 215 and double feeding of the documents 69,
It's rotating backwards little by little. When the conveyance motor 233 is turned on, its drive is transmitted to the upper separation roller 215a via the separation drive gear 277.The boss portion of the zero separation drive gear 277 is connected to an eccentric cam as shown in FIGS. 10 and 11. When the eccentric cam rotates, the actuating lever 275 swings along the shape of the cam due to the elastic force of the actuating lever 275 and the spring 278. A one-way clutch 279 is press-fitted into the operating lever 275, and when the operating lever 275 moves upward, the lower separation roller 215b also rotates. In order to prevent these separation rollers 215 from being stained by originals such as pencil originals, the gap between the separation rollers 215 is released every time a copy is made to prevent smearing. That is, the first
As shown in FIG. 2, the release shaft 28 has a separation roller release eccentric cam 281 attached to the upper separation roller 215a.

I'm stuck in 84. The other end of this adjustment plate 283 is fitted onto the shaft of the lower separation roller 215b. Further, another eccentric cam 278 is provided at one end of the release shaft 282,
It can be driven by the lever 276 of the separation roller release solenoid 285. With this configuration, when the separation roller release solenoid 285 is turned on, the plunger of the solenoid 285 is attracted, thereby operating the lever 276 and rotating the eccentric cam 278. This rotation causes the release shaft 282 to also rotate, and the rotation of the release shaft 282 also causes the separation roller release eccentric cam 281 to rotate. Then, the adjustment plate 283 is moved to the support shaft 286 by the rotation of the separation roller release eccentric cam 281.
The lower separation roller 215b moves downward, and the gap between the upper and lower separation rollers 215 is released. 13 to 16 are explanatory diagrams showing details of the transport section of the document transport unit 51, in other words, the opening (lift)/close detection of the pressure plate 288. As shown in FIG. 13, the document conveyance unit 51 is provided with a cent detection sensor 289 for a pressure plate 288. This set detection sensor 28

[5. Overall Control Concept] The control performed when the respective sections configured as described above are combined will be schematically explained. Although the figure is skipped, a conceptual diagram of the control is shown in FIG. 134.As can be seen from this figure, the copying machine main body 1, the multi-stage ADF 49, and the finisher 11 each perform various checks or processes upon input. That is, in the copying machine main body 1, the initial processing 13 is first performed.
4-1 is executed, and then standby processing 134-2, pre-processing and copying processing 134-3, and post-processing 134-4 are executed, respectively. An error mode 134-5, typified by error check, is set for each of these processes, so that it can handle various types of errors. The initial processing 134-2 mainly includes display initial processing and flag initial processing. Further, the standby process 134-2 includes a key manual process and a mode setting process. Furthermore, preprocessing and copy processing 134-3
includes repeat processing, and post-processing 134-4 refers to processing after the repeat ends.

In the multi-stage ADF 49 and finisher 11, mode processing, abnormality checks 134-6, 134-8, and timing processing 134-7, 134-9 are performed, and these are repeatedly executed.

[6. Operation Control of Each Part II] The respective parts configured as described above and the control of the overall operation of the copying machine system formed by these respective parts will be described with reference to flowcharts. (6.1 Overall General Control) Since the copying machine 1 according to this embodiment is equipped with a five-stage multi-stage ADF 49 on the document feeding side, it is possible to sequentially execute a plurality of jobs. In other words, a plurality of jobs (up to five in the embodiment) are entered as a reservation mode, the input is memorized, and the copy execution order is selected to ensure high copy productivity (processing according to the job content is performed). Of course, the normal copy mode can also be selected, and the reservation mode and normal copy mode are selected using non-volatile RAM data or a dip switch on the printed wiring board. There are copy operation processing, copy ejection processing, and original document processing.In the copy operation processing, the copy operation is performed according to the set mode in both reservation mode and normal mode.In the copy ejection processing, the copy operation is performed according to the set mode. Sort according to mode,
Performs stapling and other processing. In addition, in the sort mode, the bottom bin of the 20 bins of the finisher 11 is
The topmost bin is the first bin when in staple mode. In document processing, documents are discharged to a shift tray 392, a sorting bin (sheet storage bin 57), or the like according to a preset mode. When discharging onto the sort bin, this process is executed after all copy discharging processes are completed. (6,2 Reservation mode) Reservation mode means setting multiple jobs in advance and
This is a mode in which the start timing etc. of the copying operation are determined and executed on the copying machine side, and the job processing method and other aspects are the same as normal copying operations. The conditions for setting the reservation mode are: ■ Peripheral devices (
(Each option group) must be specified; and ■ Reservation mode must be selected. In this case, the condition (2) is determined depending on whether each option group is connected online through serial communication. If this condition is satisfied, it is possible to select and execute both the reservation mode and the normal copy mode, so as mentioned above, either one can be selected by using means such as rewriting data in the non-volatile RAM 577 or using a depth inch on the printed wiring board. do. The outline of this reservation mode setting is as follows. In addition, please refer to FIG. 53, which will be described later, for each part of the operating section.

Details of the processing at this time will be explained with reference to the flowcharts of FIGS. 50 and 51. FIG. 50 shows the processing procedure for setting the reservation mode. After executing a subroutine for serial transmission/reception processing with peripheral devices in step 550-1, check whether the device is connected to the finisher 11 (step 55 (12), hereinafter referred to as (The word "step" is omitted in parentheses), whether the original stacking unit 52 is connected (S50-3), whether the multi-stage unit 50 is connected (S50-4), and whether the original reversing unit 1-52 is connected. It is determined whether they are connected (S50-5), and if all are connected, the process returns after allowing the setting of reservation mode in step 5506.Also, if connected in each step from steps 550-2 to 350-5, the process returns. If there are any peripherals that you do not have, please proceed to step 5.
At 50-7, setting of the reservation mode is prohibited and the process returns. Then, the process moves to the process shown in FIG. 51, and if the reservation mode setting is permitted in step 551-1, step 551
Select the reservation mode with -2. This reservation mode can also be selected using the nonvolatile RAM 577, dip switch, or other means as described above. and,
If the reservation mode is selected, copy control is executed in the reservation mode in step S51-3, and then in step S551-3.
If the setting of the reservation mode is not permitted in step S551-2, and if the reservation mode is not selected in step S551-2, copying is performed by normal key manual processing in step S51-4. Note that when the reservation mode is selected in step 551-2, inputting, changing, and clearing the reservation mode job all require manual input of a three-digit number (recitation code). This is to prevent the job from being cleared or changed by other operators. The processing at this time will be specifically explained with reference to FIG. In this process, first, it is determined whether the reservation mode key is turned on. The reservation mode key 661 is connected to the print key 66 as shown in the front view of the main part of the operation section in FIG.
3, and between the reservation mode key 661 and the print key 663, a mode clear key 665 and an interrupt key 667 are provided. To the left of the print key 663 is a numeric keypad and clear/stop key group 669.
However, above it is a reservation selection key group 671 for selecting 5 types of reservation modes, and on the right side is an enter key 673.
are arranged respectively. Above each key in the reservation selection key group 671, there are five display elements (
Further, on the right side, there is a reservation LED as a display element for confirming that a reservation has been accepted.
A reservation error LED 679 indicating a reservation error is provided. Therefore, if it is determined in step 552-1 that the reservation mode key 661 is turned on, it is determined in step 352-2 whether or not the reservation LED is turned off, and the reservation mode key 661 is turned off.
If so, turn on the reservation LED 677 (552-3) and operate the numeric keypad 669 to enter the 3-digit recitation code (
S52-4). If the mode clear processing 669a after code input is not turned on (No in S52-5), the reservation selection key group 6
It is determined whether any of the keys P1 to P5 of 71 is turned on (S52-6). This step 55
If it is determined in step 2-6 that any key is turned on, it is determined whether the LED 675 corresponding to that key is turned off (S52-7). If it is OFF, the LED corresponding to that key is turned on in step 552-8.
675 blinks and makes a reservation in step 552-9.
Turn on 77. Thereafter, the three-digit code data is stored in the memory (552-10), and a code manual flag is set (S52-11). The subroutine of step 552-12 is then executed to set the mode using each reservation mode key 661, and the subroutine of step 552-13 is to perform mode check processing. When this process is finished (YES at 552-14), the mode clear key 665 is
If it is not N (No at 352-15), stop and clear timer 1 (552-16), lower the timer 1 start flag (S52-17). After that, it is determined whether the enter key 673 is turned on (552-18), and if it is turned on, the LED 675 of the target reservation selection key 671 is turned on (
352-19), turn off the reservation LED 677 (352-

After 59-21>, return. FIG. 54 is a memory map schematically showing the code data stored in this memory. Note that if it is determined in step 552-18 that the enter key 673 is OFF, the process returns directly. If the mode clear key 665 is turned on as determined in step 352-15, step 552-2
2 mode clear processing is performed and the enter key 673 is set to O.
It is determined whether the enter key 673 is turned on in step S52-23.
It is determined in step 2-24, and if it is standing, it is further determined in step 55225 whether or not timer l is being counted and amplified. If timer 1 is counting up, clear the mode setting corresponding to the key selected by the reservation selection key 671 (552-26);
After turning off the corresponding LED 675 (552-27) and turning off the reservation LED 677 (852-28), the code manual flag is lowered (S52-29). Next, the timer 1 is stopped and cleared (352-30), the timer 1 start flag is lowered (S52-31), and the process returns. In addition, according to the judgment of step 551-23, the enter key 6
If 73 is OFF, the processing from step 55230 onward is executed as is. Further, when it is determined in step 552-23 that the timer start flag is not set, the 0°5 second timer 1 is started and the timer 1 start flag is set (S5
2-32) Return and when it is determined in step 352-25 that timer 1 has not counted up,
Return as is. If the determination in step 552-14 is that the mode check process has not yet been completed, step 552
-33, the paper check is performed to see if the number of sheets has been exceeded for each mode, and the check status is displayed. If the mode clear key 665 is turned on (YES at S52-34), step 552 The process after the mode clear process of step -22 is executed, and if it remains OFF (No in S52-34), the process after step 552-12 is executed. Further, if the LED 675 selected by the reservation selection key 671 in step 552-7 is ON, it is determined whether the LED 675 is blinking (552-35). LED
675 is turned off (S52-36) and the 3-digit code data in the memory is cleared (352-37). After that, after lowering the code input flag 552-38) and clearing all modes (S52-39), the reservation LED 677
blinks (S52-40) and returns. On the other hand, if it is determined in step 551-35 that the LED 675 is not blinking, the 3-digit code data is loaded from the memory (S51-41) and the input 3-digit code and the 3-digit code data loaded from the memory are It is determined whether or not the digit code matches (352-42), and when it is determined that they match in this step 552-42, the LED 675 corresponding to the key to be selected is blinked (S52-42). 43), loads the mode data stored in the memory 552-44), and performs settings according to the mode data (S52-45). Then, the code input flag is set (S52-46), and the LED 675 corresponding to the selected object is turned on (S52-47).
) o (After D, execute the process from step 552-13 onward. Also, if it is determined in step 55242 that the codes do not match, proceed to step 552-13 described later.
The process moves to step 48 and subsequent steps. Note that this step 552-4
It is also possible to set the reservation error LED 679 and other display elements to be lit for a certain period of time before proceeding to the processing from step 8 onwards. Further, if the mode clear key 665 is turned on in step 552-5, the key power of the 3-digit recitation code is cleared (352-48) and the process performs 7 turns. Further, in step 552-6, the target reservation selection key 671 is turned off.

5 Place the original on top. Then, an execution job is selected and executed according to each reservation mode. (6,3 Execution of Reservation Mode Jobs) When the copying machine 1 is in the reservation mode and in the standby state, the execution order of the five reservation modes (jobs) is determined by the following factors. - If everything is in staple mode, the input order is the same. - In the non-stapling mode, if the number of empty sheet storage bins of the finisher 11, that is, the number of bins not used in the non-stable mode, allows the next job to be executed, the non-stable mode is executed. In this embodiment, in the non-stable mode, the sheet storage bin 5 of the finisher 11 is
It is set to exist on 7. This is intended to allow the operator to remove the sheet from the storage bin 57 during that time. However, if the sheets are left on the sheet storage bin 57 for more than 5 minutes, the execution of the next job will be delayed. to make it available for other jobs to run. Therefore, the processing time of the entire job is determined by how the five minutes are utilized. FIG. 55 is an explanatory diagram showing the relationship between job reservation and execution in the reservation mode. This figure shows the order in which reserved jobs are accepted, the reserved mode, the number of bins to be used, the number of bins with remaining sheets, and the execution order of reserved jobs. The following modes are set for this reserved job. 1) (a) Staple 5 sets of copies (BL originals are also stapled (C) The number of bins used is 5 (The number of bins where DL sheets remain is 0 2) (Sorting 8 sets of al copies) (b) Originals are stored in the sort bin (C The number of bins used is 8 + 1 (d) The number of bins with sheets remaining is 9 3) (Al copy staples 5 copies (BL original is also stapled (C) The number of bins used is 5 (d) The number of bins with sheets remaining is 0 4 ) (a) Copy sorting 15 copies (b) The original is on the shift tray (C) The number of bins used is 15 Td) The number of bins remaining is 15 5) (al Copy staple 10 copies (bl The original is on the shift tray ( C1 The number of bins used is 10 (The number of bins with d3 sheets remaining is 0 6) (5) Copy sorting 15 copies ('b) Originals are sorted bins (C) The number of bins used is 15 + 1 (d) The number of bins with remaining sheets is 16 7) (Al copy sorting 15 copies (BL original is sorted bin (C) number of bins used is 15 + 1 FDL sheet remaining number of bins is 16 8) (Al copy staple 20 copies (b) original is shift tray ( C) The number of bins used is 20 (The number of bins with DL sheets remaining is 0. 9) (a) Copy staple 10 copies (BL original is stapled (C) The number of bins used is 10 fd) The number of bins with remaining sheets is 0. 10) (Al Copy sorting 5 copies (b) Originals are sorted in bins (C1 Number of bins used is 5 + 1 (d) Number of bins remaining sheets is 2) If you run the job in the order entered in the job reservation, , when the jobs up to 5) are completed, the job time of 1) + the job time of 2) + 5 minute timer (wait time in menstable mode) + the job time of 3) + the job time of 4) another 5 minute timer + 5) job time. However, since the 5-minute timer is a timer that starts from the end of the job, the job that this timer starts, i.e., non-stable mode, is set to be processed later, and the above-mentioned reserved job reception is in the order of 1)-2). -3)

The order of execution is shown in the rightmost column of FIG. Note that the completed jobs are shifted in order as shown in FIG. Processing for executing these reserved jobs will be described in detail with reference to flowcharts. FIG. 57 is a flowchart showing a procedure for determining the execution order of jobs in reservation mode. In this procedure, first, in step 557-1, it is determined whether any of the keys P1 to P5 of the reservation selection key 671 is turned on. If it is ON, step 557-
In Step 2, call up the mode data and number data set by the reservation selection key that was turned ON, and judge whether or not the stable mode is set depending on whether the stable mode flag is set.S57-

), it is determined whether the sort mode flag is set (S57-12). When it is determined in step 557-12 that the ORG sort mode flag remains down, the ORG sort flag is set to 0 (557-16), and the numbers of keys PI to P5 of the target reservation selection key 671 are set. is the FPOH address in binary (P○ is Pl, P2.P3.P4
and 5)) is input (S57-17
) and return. When it is determined in step S5'1-12 that the sort mode flag is set, the ORG sort flag is set (
35'l-18), advance the remaining paper pin counter by 1 (S5'
l-19), and also increments the used pin counter by one step (
S57-20). Then, it is determined whether the remaining paper pin counter is larger than 20 (557-21), and if it is, 20 is set in the remaining paper pin counter (S57-22). Next, determine whether the used pin counter is greater than 20 (55723),
If it is larger, add 20 cents to the used pin counter. Note that when it is determined in step 557-21 that the remaining paper pin counter is 20 or less, and in step 557
If it is determined at -23 that the used pin counter is 20 or less, the process jumps to the next step, performs the next process, executes the process at step 557-17, and then returns.

Step 857-17 and the above PO indicate the state of the reservation mode selected by the reservation selection key 671 (PL. 2.3, 4.5). As shown in the flowchart of FIG. 58, job selection begins by first determining the state of the job selection memory. Job selection memory is 0 in step 358-1
If not, return; if 0, step 358-2
It is determined whether the staple flag of FPMIL is set, and if it is set, the numerical value of the number (Pi to 5) of the job to be executed first is stored in the upper four bits of the job selection memory at step 358-10. A stable flag is transmitted from the CPU 573 on the copying machine 1 side, and is "1" indicating execution of the stapling operation. If the stable flag is not set in step 35B-2, step 358-
In step 3, it is determined whether or not the FPMIL sort flag is set. If it is not set, the process of step 358-10 is performed. If it is set, the remaining sheet pin counter of FPMIL and the used pin counter of FPMIL are called in step 358-4. 0 Then, in step 558-5, it is determined whether the sum of the number of used pin counters of FPMMIH and the number of used pin counters of FPMIL is 20 or less. If it is less than 20, the process of step 358-10 is executed; if it is greater than 20, it is determined in step 55B-6 whether the stable flag of the FPM 2L of the second job is set. If it is, that is, if stapling is to be performed, the numerical value of the job number (PL to 5) corresponding to the second job is stored in the upper 4 bits of the job selection memory and the process returns. If the stable flag is off in step 558-6, the FPM3L of the third job is determined in step 55B-8.
It is determined whether the stable flag is set, and if it is set, the numerical value of the job number corresponding to the third job is stored in the job selection memory and the process returns. Furthermore, if the vehicle has descended, the process of step 358-10 is executed and the process returns. (Processing with 6, 4 Original Processing Keys) FIG. 59 shows an example of the mode selection keys and the display of the selected mode. A copy processing key 701 and an original processing key 703 are respectively provided, and above them are the staple mode. Display LED 701a, sort mode display LED 70
l b, stack mode display LED 701c, staple mode display LED 703a, sort pin mode display L
ED703b, shift tray mode display LED703C
are provided for each. Therefore, in the mode set by the document processing key 703, the CP
U573 first checks the finisher connection flag and document reversing unit connection flag (360-1.
Step 560-2). If each connection flag is O, that is, if either the finisher or document reversing unit is not connected, return; if connected, step 36
At 0-3, it is determined whether the reservation mode setting is completed. If the reservation mode is in the process of being set, the process returns; if the reservation mode has been set, step 560-4
Now let's determine whether interrupt mode is enabled. If it is not the interrupt mode, it is further determined in step 560-5 whether the document processing key 703 is turned on. If the document processing key 703 is turned on as determined in step 560-5, stable mode is displayed in step 560-6.
Determine whether ED703a is turned on. If the document processing key 703 is not turned ON in the judgment at step 560-5, it is determined whether the stable prohibition flag is set (560-14), and if the flag is set, that is, the state is in the stable prohibited state. If it is, return, and if the stable prohibition flag is off, it is determined whether the reservation mode is set (S60-
15). If it is determined in step S60-15 that the reservation mode is not set, the process returns, and if the reservation mode is set, it is determined whether the sort bin mode is set (S6
0-16). If it is determined in step 560-16 that the mode is the sort bin mode, the process returns; if the mode is not the sort bin mode, it is determined whether the shift tray mode is selected (560-17). If the shift tray mode is selected in step 560-17, the process returns; if not, the stable (ORG) mode subroutine shown in the flowchart of FIG. 62, which will be described later, is executed (S60-18) and the process returns. Furthermore, if the stable mode display LED 703a is ON in the judgment at step 560-6, the 63rd
The sort bin mode subroutine shown in the flowchart in the figure is executed (S6019), and if the stable mode display LED 703a is not ON, it is determined whether the sort bin mode display LED 703b is ON (S60-7). ). If it is determined in step 560-7 that the sort bin mode display LED 703b is not ON, then the shift tray mode display LED 703b is turned on.
703c is turned on (S60
-8). If the shift tray mode display LED 703c is ON as determined in step 5608, it is further determined whether the reservation mode is set (560-9
). If the reservation mode is not set in step 560-9, execute the normal mode subroutine shown in the flowchart of FIG. ,
The stable mode subroutine shown in the flowchart of FIG. 62, which will be described later, is executed (S60-11) to stabilize the original, and then the process returns. On the other hand, if the sort bin mode display LED 703b is ON as determined in step 560-7, it is determined whether the document stack unit 52 is connected (3
60-12>, if the document stacking unit 52 is not connected as determined in step 560-12, step 5
The process of step 60-8 is skipped and the processes of step 560-9 and subsequent steps are executed, and if the document stacking unit 52 is connected, the shift tray mode subroutine shown in the flowchart of FIG. 64, which will be described later, is executed ( 560-
13) After that, return. Note that when it is determined in step 560-4 that the mode is not interrupt mode, and when it is determined in step 860-8 that the shift tray mode display LED 703C is in the OFF state, the normal mode subroutine of step 560-10 is directly executed. Execute and return. The normal mode subroutine in step 560-10 described above is processing as shown in the flowchart of FIG. 61. This process sets the stable mode flag, sort bin mode flag, and shift tray mode flag to O, respectively. 86
1-3) In addition, stable mode display LED 703
a, sort bin mode display LED 703 b and shift tray mode display LED 703 C are turned off respectively.
This is a process of F and return. Steps 360-11 and 560-1 described above
The stable mode subroutine in 8 is the 6th stable mode subroutine.
This process is as shown in the flowchart of FIG. In this process, the stable needle end check subroutine shown in the flowchart of FIG. 65, which will be described later, is executed.
62-1), then it is determined whether the reservation mode is set (S6
2-2) If the reservation mode is not selected in step 562-2, it is further determined whether there are any remaining sheets in the finisher bin (sheet storage bin 57) (S62-3). If there is any remaining paper, please “remove the sheet from the bin”
This guidance is displayed (S6: ?-4), the staple mode flag is set, and the staple mode is set (S62-5). Next, lower the sort bin mode flag and shift tray mode flag.5
62-6, 562-7), staple mode display L

D7θ3b and shift tray mode display LED703
c are respectively turned OFF (S62-8) and the process returns. Note that if it is determined in step 562-2 that the mode is reservation mode, and if it is determined that there are no remaining sheets in the sheet storage bin 57, the process jumps to step 562-5 and the subsequent processes are executed. The sort bin mode subroutine in step 560-19 described above is the process shown in the flowchart of FIG. 63. In this process, first, it is determined whether or not it is in reservation mode (5631), and if it is in reservation mode, “
5 minutes after the JOB ends, the nest will be pulled.
The X power event is displayed (S63-2), the staple mode flag is lowered (S63-3), and the staple mode is canceled. Then, the sort bin mode flag is set (S63-4) to set the two-to-bin mode, and the shift tray mode flag is set (S63-5).
) Eliminate shift mode. Next (for this reason, turn off staple mode display LEDT 03a and shift tray mode display LED 703C, sort bin mode display LE
Turn on D703b (363-6) and return. It should be noted that if the above-mentioned determination of the steering knob 563-1 is not in the reservation mode, the process from step 563-3 onward is executed without displaying the power identity of the steering knob 563-2. The shift tray mode subroutine in step 560-13 described above is the process shown in the flowchart of FIG. 64. This process sets the stable mode flag and the sort bin mode flag (564-1, 564-2), sets the shift tray mode flag (S64-3), sets the shift mode, and turns on the shift tray mode display LED 703c. is turned on, the staple mode display LED 703a and the sort bin mode display LED 703b are turned off, and the shift tray mode is displayed (S64-5), and then the process returns. The staple end check subroutine in step 362-1 described above is the process shown in the flowchart of FIG. 65. That is, in this process, it is first determined whether the staple mode is selected (S65-
1). If the mode is the staple mode in this determination, it is determined whether the end of the staple has been reached (S65-
2). Detection of this end is determined by whether the stable abnormality 1 flag is set. Then, if the determination in step 565-2 is that the stable abnormality 1 flag is set,
Since the staple has reached its end, set the staple end flag (S65-3) and turn on the staple end display.
65. -4) Prohibit input of reservation mode (S65
-5) Return. On the other hand, if it is determined in step 565-1 that the mode is not the stapling mode, it is not determined whether the mode is the reservation mode or not.
), if not in the reservation mode, turn off the needle end display 565-7) and lower the needle end flag (S65-8).
). Next, it is determined whether the reservation mode is set (S65-9). If it is determined in step 565-9 that the reservation mode has been set, input of the reservation mode is permitted (S65-10) and the process returns; if the reservation mode has not been set, the process returns directly. Note that if it is determined in step 565-2 that the stable abnormality 1 flag is not set, the needle end has not been reached, so the process from step S657 onwards is executed continuously, and the reservation is made in step 565-6. If it is determined that the current mode is selected, the processing from step S65-2 onwards is executed successively. (Processing by the 6,5 copy processing key) In the mode set by the copy processing key, the 66th
The processing shown in the flowchart in the figure is executed. In this process, it is first determined whether the finisher flag is set (S66-1), and if the finisher flag is set, it is determined whether or not the preheating mode is set (566-2).
, returns if not standing. Step 566-2
If it is determined that it is in preheating mode, it will return, and if it is not in preheating mode, it will further determine whether it is in the process of setting preheating mode (
S66-3). If it is determined in step 566-3 that the preheating mode is in the middle of setting, the process returns, and if the setting is not in progress, it is determined whether or not the double-sided back copy mode is in progress (S66-4). If it is a double-sided back copy, return; if not, determine whether it is in the double-sided front copy mode (S66-5)
. If you are in double-sided front side copy mode, it is difficult to determine whether the copy is in the START/7B state during copying.56
6-6), if it is stopped, return, and if copying continues, it is further determined whether duplex mode is used (3
66-7). If it is determined in step 5665 that the double-sided front copy mode is not in effect, the process proceeds to step S66-7 without performing the process of step 566-6. If the determination in step 366-7 is duplex mode, it is further determined whether there is copy paper in the duplex tray 43 (566-8), and if there is copy paper, the process returns; if not, it is determined whether the mode is in interrupt mode. (36
6-9) If it is determined in step 566-7 that the mode is not duplex mode, the process directly proceeds to step 566-9 without performing the process in step 566-8. If the determination in step 566-9 is the interrupt mode, the process returns, and if not the interrupt mode, it is further determined whether the copy processing key 101 is turned on. If the copy processing key 701 is OFF, the process returns; if it is ON, it is determined whether the staple mode display LED 701a is ON (S66-11). If the determination in step 566-11 is ON, the sort mode subroutine shown in the flowchart of FIG. 69, which will be described later, is executed (S66-1
4) Return, and if it is OFF, it is further determined whether the sort mode display LED 701b is ON (S66-12). ON at step 566-12
If so, execute the stack mode subroutine shown in the flowchart of FIG. 70 (described later) (S66-17).
Return. If it is OFF, it is determined whether the stack mode display LED 701C is ON (S66-13). If the stack mode display LED 701C is ON as determined in step 866-13, execute the normal mode subroutine shown in the flowchart of FIG. 68 (described later) and return (S66-16); Execute the staple mode subroutine shown in the flowchart in Figure 67 (S6
6-15) Return. The normal mode subroutine in step 566-16 described above is the process shown in the flowchart of FIG. 68. This process uses the sort mode flag,
868-1, 368-2, 368-3) lower the stack mode flag and staple mode flag, respectively.
, further lowering the sort, stack, and stable MAX flags 868-4), and finally the stapling mode display LED 701a to indicate that these modes are not present. Turn off the sort mode display LED 701b and stack mode display LED 701C (368-
5). The sort mode subroutine in step 566-14 described above is a process as shown in the flowchart of FIG. 69. In this process, first, it is determined whether the mode is reservation mode (S69-1), and if it is the reservation mode, it is further determined whether the sort prohibition flag and the stack prohibition flag are set (S69-2). If step 5
If the sorting prohibition flag and stacking prohibition flag are set in step 69-2, it means that the mode is not sorted, so the 68th
The process shifts to the process shown in the flowchart in the figure, and processes from step 7 568-1 onwards are executed. If the flag is not set, a guidance message is displayed stating that "the machine will be stabilized 5 minutes after the JOB ends" (S69-3). Thereafter, the staple mode flag and stack mode flag are lowered (569-4, 569-5), the sort mode flag is set (S69-6), and the staple mode display LED 701a and stack mode display LE are set.
Set D701c to 0FFL and turn on the sort mode display LED.
(S69-7) Return. Note that if the determination in step 569-1 is not the reservation mode, the process directly advances to step 569-4 and the subsequent processes are executed. The staple mode subrune in step 566-15 described above is the process shown in the flowchart of FIG. 67. In this process, first, the staple end check subroutine shown in FIG. 65 is executed (5671), and it is further determined whether there is any remaining paper in the sheet storage bin 57 (S67-2). If there are any remaining sheets, determine whether you are in reservation mode (567-3), and if you are not in reservation mode, select "Please remove the sheet from the bin."
This guidance is displayed and the sort mode flag is lowered (S67-5). When it is determined in step 567-2 that there are no remaining sheets in the sheet storage bin 57, or when it is determined that the reservation mode is in step 567-3, the process directly proceeds to step 567-5. Then, in step 567-6, the stack mode flag is lowered, and in step 567-7, the stable mode flag is set, and only the staple mode display LED 701a is turned on, and the process returns. The stack mode subroutine in step S66-17 described above is a process as shown in the flowchart of FIG. 70. In this process, first, it is determined whether the mode is reservation mode (S70-1). If it is in the reservation mode, execute the process from step 568-1 in the flowchart of FIG.
2.570-3), set stack mode flag (
570-4). And stack mode display LED 7Q
Only 1c is lit (570-5), and it is further determined whether it is in the reservation mode (S70-6). If the determination in step 570-6 is the reservation mode,
The process returns after displaying the guidance "Stapling will begin 5 minutes after the JOB ends" (S70-7).Also, if it is not in reservation mode at step 570-6, the process returns directly. In this embodiment, since there are only 20 sheet storage bins 57, consideration must be given to the number of copies, that is, the number of copies entered using the numeric keypad.The processing for checking the number of copies, that is, changing the number of copies, is shown in FIG. and Fig. 72. Fig. 71 is a flowchart of processing in stable mode. In this processing, as mentioned above, there are only 20 sheet storage bins, so in sort mode and stable mode, up to 20 sheets can be stored. Therefore, first, it is necessary to determine whether the sort mode flag and stable mode flag are set.
), if it is not set, return; if it is, it is determined whether the copy number exceeds 20 (S71-2
). If the judgment in this step 571-2 exceeds 20, turn on the display of "Copy number exceeded" 571-3
), further sets the number of copies to 20 (571-4) and returns. If the judgment in step 571-2 does not exceed 20, the display of "Copy number exceeded" is turned off.
F and return. On the other hand, in stack mode, as shown in the flowchart in Figure 72, first check whether the stack mode flag is set (572-1), and if it is not stack mode, return; if stack mode, the number of copies is set. It is determined whether the value is larger than 50 (S72-2). If the number of copies stored exceeds 50 as determined in step 572-2, the display of "1 copy number exceeded" is displayed at 0NL.
(S72-4), set the copy number to 50 (S72-4)
), if it is determined in step 572-2 that the number of copies is less than 50, the display of "Number of copies over 1" is turned off and the process returns.The number 50 indicates the number of sheets that can be stacked. In the reservation mode, since the number of stacked sheets is limited, it is necessary to warn of the maximum number of originals.Therefore, in the reservation mode, the process according to the flowchart in FIG. 73 is executed. In the process, first check whether the original (ORG) stapling mode flag is set.
73-1), if the flag is not set, next check whether the sort bin mode flag is set (S73
-2). If the sort bin mode flag is not set, return; if it is, it is further determined whether it is in reservation mode (373-3), and if it is in reservation mode, the number of sheets per document is 5.
If the number exceeds 0, the documents will be ejected to the blueprint tray.
This guidance is displayed (S73-4), and if it is not the reservation mode, the process returns directly. Note that if the determination in step 573-1 is that the document stable mode flag is set, step 5
The processing from step 573-3 onwards is executed without performing the processing at step 73-2. Furthermore, since there is a limit of 50 copies in the copy stapling mode, it is necessary to warn of the maximum number of copies of 50 copies in the reservation mode. Therefore, in this process, as shown in the flowchart of FIG. 74, it is necessary to check whether the staple mode flag is set (574-1).
If the flag is not set, it is determined whether the sort mode flag and stack mode flag are set (S74-
2). If the user is not standing, the process returns; if the user is standing, it is further determined whether the user is in reservation mode (S74-3).
. If it is in the reservation mode, a guidance message is displayed saying "If the number of sheets exceeds 50, the remaining sheets will be discharged to the blueprint tray" (S74-4), and if it is not in the reservation mode, the process returns directly. Note that if the determination in steps 374 to 1 is that the staple mode flag is set, step 574
Step 574-3 and subsequent steps are executed without performing step 574-2. [7. Differences in flow due to differences in original and transfer paper modes] Figure 75 shows a schematic configuration of the copying machine 1 in Figure 1.

The transfer paper 37 is supplied from the multi-stage unit 50, stored once in the document stack tray 382, and then transferred to the sheet storage bin 57 ("1101" - R6, 1 in the figure).
are discharged to the sheet storage bin 57 in sort mode (
100''), or discharged to the sheet storage bin 57 in stack mode ("101" - R, sb shown). Note that FIG. 86 is an example of a mode related to the processing of the original 69 and the transfer paper 37.

[8. Processing after Copy Discharge] Next, processing control after discharging the transfer paper 37 after copying will be described. Note that the timing of this process is based on the timing chart of FIG. 87, and a detailed explanation will be omitted. (8,1 Initial Processing) FIG. 88 is a flowchart showing a general processing procedure for setting the initial operation. In this process, first, an initialization subroutine is executed (58B-1) to clear the port mode and RAM, and further clear the flag and counter. Next, set the finisher connection flag (
388-2), transmits and receives data to and from the CPU 573 on the copying machine side (
S 88-3). Thereafter, the bin home request flag is set (388-4), the switching wheel 477 is initialized (588-5), and the process returns. The bin home request flag is a flag indicating that the sheet storage bin 57 is to be moved to the home position, and "1" indicates that it is being returned to the home position. FIG. 89 is a flowchart showing a more detailed initial setting operation procedure. In this process, first, check whether the initial request flag is set to 1, that is, whether the flag is set.
), if the user is not standing, returns; if the user is standing, it is determined whether the stable home position sensor is turned on (389-2). The initial request flag is sent from the copying machine 1 side to the finisher 11 side,
Also on the finisher 11 side, there is a flag that says “work”.
Jogger 63, seat storage bin 57, drop roller 432
, 433, checks for initial jams, etc., and when finished, the finisher 11 sets "0" and sends it to the copying machine main body. If the staple home position sensor 429 is not turned ON in step 589-2, a stapler home request flag is set (S89-3), and if it is not turned ON, the jogger 63 is set to the specified jogging position. It is determined whether the jogger ready flag ("1" indicates the end of movement) is set (S89-4). If the jigger ready flag is set in Step 389-4, the jogger home return flag is set (S89-5), and if the jogger ready flag is not set, the drop/roll home position sensor is turned ON. (S89-6). The jogger home return flag is a flag indicating an operation to return the jogger 63 to the home position, and "1" indicates that the jogger 63 is being returned to the home position. If the dropping roller home position sensor is not turned ON in the judgment in step 589-6, the dropping roller removal return flag is a flag (“1” indicates that the returning operation is in progress) to return the dropping roller to the home position. (S89-7), and if the drop roller home detection sensor 54 is turned on, the bin home detection sensor 54 is turned on.
2 is turned on (S89-8)
. If the bin home detection sensor 543 is not ON, a bin home request flag is set (389-9), and if the bin home detection sensor 543 is ON, the first transfer paper entry detection sensor (transfer paper entry detection It is determined whether the detection signal of the sensor 1) 534 indicates that the transfer paper 37 has entered (S89-10). If the determination in step 58910 is that there is no paper, it is further determined whether the detection signal of the second transfer paper entry detection sensor (transfer paper entry detection sensor 1) 504 indicates that the transfer paper 37 has entered (S89- 11). If step 589-1
0, or if the judgment in step 589-11 is that there is paper, a copy conveyance jam flag is set (389-1).
3) Notify the CPU 573 side that the transfer paper 37 is jammed, and if there is no paper, lower the copy conveyance jam flag (S89-12) to notify the CPU 573 side that the transfer paper 37 is not jammed. What is the copy conveyance jam flag? First or second transfer paper entry detection sensor 5
Corresponding to the jam detected at 34,504, 11" indicates a jam, and "0" indicates no jam. Then, the first and second document entry detection sensors 5
36,502 (Document entry detection sensor 1゜2) Determine whether the detection signal indicates paper present (389-1
4). If the state is out of paper, the document jam flag is lowered (S89-15), and if there is paper, the document jam flag is set (S89-16), and the detection signal of the release sensor indicates that there is paper. It is determined whether the state has been reached (S89-17). Note that the document jam flag refers to the first and second document entry detection sensors 536.5.
Corresponding to the jam detected at 02, there is a jam at “1”,
“0” indicates no jam. If the judgment in step 589-17 is that there is no paper, the release jam flag corresponding to the jam detected by the release detection sensor 542 is lowered (589-18), indicating that there is a jam when it is "1" and that there is no jam when it is "0";
If there is paper, set the discharge jam flag (S89-
19), Next, it is determined whether the detection signal of the tray paper ejection detection sensor 538 is in the paper presence state (S89).
-20). If there is no paper, correspond to the jam detected by the tray paper discharge detection sensor 538, and lower the paper discharge jam flag which indicates a jam with "l" and no jam with "0"589-21); If there is paper, a discharge jam flag is set (S89-22), and it is further determined whether the door open sensor is ON (S89-23). The door open sensor is set to O based on the judgment in step 589-23.
If it is in the FF state, it corresponds to the door opening of the finisher 11, and lowers the door open flag which indicates the open state at 1" and the closed (normal) state at "0" 589-24
> If it is ON, set the door open flag (
S89-25), and this time it is determined whether the jogger home return flag is set (S89-26). If the jogger home return flag is not set, check whether the bin home request flag is set (589-27), and if it is not set, check whether there is any remaining paper in the sheet storage bin 57 (S89-27). 28
). If there is no remaining paper on the tray, lower the tray remaining paper flag (589-29); if there is any remaining paper on the tray, set the tray remaining paper flag (S89-30). Is the staple end sensor turned on? How will you judge? (S89
-31). If the needle end sensor is in the OFF state, the needle end flag is lowered (589-32), and if it is in the ON state, the needle end flag is set (S89-33), and the switching wheel initial processing subroutine is executed (S89-32). 34)
. Note that if the jogger home return flag is set as determined in step 389-26 and the bin home request flag is set as determined in step $89-27, the process directly proceeds to step 589-34. . When the process of step 589-34 is completed, it is determined whether the bin home request flag is set (589-35), and if the bin home request flag is set, the flag is sent to the CPU 573 on the copying machine side (58).
9-39), if the bin home request flag is down, it is determined whether the jogger home return flag is up (S89-36). If the jogger home return flag is set, the CPU 573 on the copying machine 1 side
If the vehicle is getting off the vehicle, it is determined whether the wheel home request flag is set (S89-37). This wheel home request flag is a request flag for setting the switching wheel 477 to the controlled home position. Step 5
89-37, if the wheel home request flag is set, the flag is also sent to the CPU 573 on the copying machine 1 side (389-39), and if it is off, the initial request flag is lowered (589-38), copying machine 1 After sending the flag to the side CPU 573 (S89-39)
Return. (8,2 Jogger Drive Process) FIG. 90 is a flowchart showing the processing procedure of the jogger drive process. In this process, first, the count up of timer 2 is checked (590-1), and if the count is not up, it is checked whether the jogging flag is set (S90-2>.This jogging flag means that the jogger fence 472 is seated). During the alignment operation “
If the jogging flag is not set, it is next checked whether the jogger home return flag is set (S90-3). If the jogger home return flag is not set, the CPU 573 on the copying machine side How to decode the data sent from 5
90-4), it is determined whether the mode reception data is 2 or 4 (S90-5). The mode reception data 2 is the code "001" shown in FIG. 77, and the mode reception data 4 is the code "011" shown in FIG. be. If it is determined in step 590-5 that the mode reception data is not 2 or 4, the process returns, and if it is determined that the mode reception data is 2 or 4, it is further checked whether the stapler home request flag is set (590-5). 6) If the stapler home request flag is set, the process returns; if not, it is further determined whether the release detection sensor 542 is set (S90-7). If it has fallen, start timer 1 (S90-8), lower the jigger ready flag 590-9), set the jogging flag (S90-10), and set the jogging flag on the data table according to the sheet size data. After selecting data (S90-11) and storing the selected jogging data in the jogging memory (S90-12), the process returns. Note that the process in step 590-11 shows a state in which the sheets are arranged. Note that the jogging memory indicates the position to which the jogger fence 472 is to be moved with the jigger home position as "O", and is used to control the movement of the jogger fence 472 in conjunction with the jogging counter. Further, if the discharge detection sensor 542 is not turned down as determined in step 590-7 described above, the jogger ready flag is activated (590-13), and the jogging data on the data table is selected from the sheet size data (590-13). S90-14). This process is in a standby state, and the jogger is evacuated from the seat. The jogging data selected in step 390-14 is stored in the jogging memory in step 590-15, and furthermore, the data in the jogging memory and the value of the jogging counter indicating the position of the jogger fence 472 with the jigger mom position as "0" are equal. If the two values are equal in the judgment at step 590-16, the jogger ready flag is set (S90-17), and the value in the jogging memory is assigned to the jogging counter (S90-16).
18). Then, set the jigger motor 463 to 0FFL (S90-1
9), lowering the jigger forward flag 590-2
0), and also lowered the jogger reverse flag (S9
0-21) Return. The jigger forward flag is a flag that indicates movement of the jigger 63 in the direction of aligning sheets, such as paper alignment, and the jogger reverse flag is a flag that indicates movement of the jigger 63 in the direction of retraction from paper alignment. If the data in the jogging memory and the value of the jogging counter are not equal as determined in step 590-16, the jogging memory and the jogging counter value are further compared (S90-22). If it is larger than the jogging counter value, set the jigger forward flag (590-23)
, fly the jogger reverse flag (S90-24)
After the jogging counter is weighted in accordance with the jigger motor drive pulse (S90-25), the process returns. On the other hand, if the value of the jogging counter is greater than or equal to the value of the jogging memory in step 590-22, the jigger forward flag is lowered (390-26), the jogger reverse flag is raised (S90-27), and the jigger motor drive pulse After decrementing the jogging counter in accordance with (S90-25), the process returns. Further, if the jigger home return flag is not set in the determination at step 590-3 described above, it is determined whether the home position sensor 471 is at the H level (S90-2).
9) If the level is L, set the jigger reverse flag (S90-30), lower the jogger reverse flag (S90-31), and check the rise of the home position sensor 471 of the jogger 63 (590).
-32). If it is determined in step 590-32 that the home position sensor 471 is not standing up, the process returns as is, and if it is determined that it is standing up, the jogger 63 is moved in the reverse direction by 3 pulses (590-33-FIG. 92). After stopping the motor 463 (S90-33) and lowering the jogger reverse flag (S90-35), the process returns. On the other hand, if the Baum position sensor 471 is at H level as determined in step 590-29, the jogger reverse flag is lowered (590-36), the jigger forward flag is raised (S90-37), and the home position of the jogger 63 is set. Check for falling edge of sensor 471 (S90-38). If it has not fallen, it returns as is, and if it has fallen, it lowers the jogger forward flag 590-39) and stops the jigger motor 463 (S90-40). Thereafter, the jogger home return flag is lowered (590-41), the jogger ready flag is raised (S9042), the jogging counter is reset (S90-43), and the process returns. Also, if the jogging flag is set as determined in step 590-2 mentioned above, check whether timer 1 is counting up (590-44), and if it is not counting up, return and count up. If so, timer l is stopped (590-45). Then, it is checked whether the value of the jogging memory and the value of the jogging counter are equal (590-46), and if they are not equal, the processing from step 590-22 described above is executed. On the other hand, if the jogging memory value and the jogging counter value are equal, the jogger motor 463 is stopped (S9
0-47), lowering the jogger forward flag and jogger reverse flag 590-48. 590-4
9) Further, it is determined whether timer 2 has started (S90-50). If timer 2 has started, the process returns directly; if it has not started, timer 2 is started (S90-51), the discharge OK flag is set (S90-52), and the process returns. Finally, if timer 2 has already counted up as determined in step 390-1, the jogging memory is unloaded (590-53), and timer 1 and timer 2 are counted up.
After clearing (S90-54) step 590-13
Execute the following processing. Note that the above steps 390-32 or step 59
0-38, the rise and fall of the jigger home position sensor 471 is checked for the following reasons. That is, as shown in FIG. 91, the jigger home position sensor filler 424 protruding from the jigger fence 472 advances and retreats, that is, reverse side (in the direction of arrow 427R) with respect to the jigger home position sensor 471 consisting of a photo interrupter. )
and move to the forward side (arrow 427 F), as shown in the timing chart of Fig. 92.
The home position of the jogger is defined as the falling edge of the home position sensor 471 (2 in the figure). This is because there is a deviation amount in the sensor characteristics between the rise and fall of the sensor, so processing is performed so that the fall of the sensor output always becomes the home position, regardless of the position shown in FIG. 92, Agz or B10. (8,3 Switching Wheel Initial Processing) Next, control of the switching wheel 415 will be explained. FIG. 93 is a flowchart showing the initial processing procedure of the switching wheel 477. In this process, first, it is determined whether the switching wheel home request flag is set (S93-1). If it is determined in step 393-1 that the flag is not set, the process returns, and if it is, it is checked whether the switching wheel 477 is rotating in the forward direction (S
932), and if it is not rotating forward, the switching wheel 477 is rotated forward (S93-3), the drive pulse counter is reset (S93-4), and the process returns. This drive pulse counter is a counter that indicates the position of the switching wheel 477, and "0" is the home position. Switching wheel 477
Used together with drive pulse memory during driving. The drive pulse memory indicates the position at which the switching wheel 477 is driven, and performs the same processing as the jogging counter and jogging memory. On the other hand, if it is rotating in the forward direction, the drive pulse output is cut off (S9
3-5) Check whether the home position sensor 545 of the switching wheel 477 is up (S
93-6). If it has not risen, check whether the drive pulse counter is 0, that is, whether it has been reset (593-7). If it has been reset, return as is; if it has not been reset, check whether the drive pulse counter is 0 or not (593-7). Move forward one step and return. Further, if the home position sensor 545 is up as determined in step 593-6, it is checked whether the drive pulse counter is O, that is, whether it has been reset (S93-9). Assign 1 to the driving pulse counter (S93
-10) Return. If it has not been reset, further check whether the drive pulse counter is greater than 150.593-11), 150
If it is below, assign 1 to the driving pulse counter (S
93-12) Return. If it is greater than 150, it is checked whether the drive pulse counter is less than 360 (S93-13), and if it is less than 360, the drive pulse output is stopped and the rotation of the switching wheel 4770 is stopped (S93-14). , lowers the wheel home request flag 593-15), resets the drive pulse counter (S93-16), and then returns. On the other hand, if the value of the drive pulse counter is 360 or more as determined in step 593-13, the drive pulse output is stopped (S93-17), the drive pulse counter is reset (S93-18), and the switching is performed. A wheel rotation abnormality flag is set (S93-19) and the process moves to an abnormality processing routine. The switching wheel rotation abnormality flag is a flag that is set to "1" if the home position cannot be detected even if the switching wheel is driven for a certain number of pulses or more, and is normally set to "0". (8,4 Switching Wheel Driving Process) When the initial processing of the switching wheel 477 is completed, the switching wheel 477 can be driven. The processing at this time will be explained with reference to the flowchart in FIG. 94. In this process, first, it is checked whether the initial request flag is set (S94-1). If the flag is set, the home request flag of the switching wheel 477 is set (S94-2), and it is further determined whether the transfer paper conveyance flag is set (S94-3). If it is not set, it means that there is no jam in the transfer paper 37, so it is difficult to judge whether the document jam flag is set or not.594-3
), the document 69 has not been jammed, so the initial processing of the switching wheel shown in FIG. 93 is executed (S94-5) and the process returns. Further, if the jam flag is set in the judgments in steps 594-3 and 594-4, it means that a jam has occurred in the transfer paper 37 or original document 69, and the process returns directly. If the initial request flag is off as determined in step 594-1, the CPU 651 on the finishing II side decodes the data transmitted from the CPO 573 side of the copying machine main body (594-6), and determines whether the mode reception data is 0. (S94-7). If it is 0, the process returns, and if it is not 0, it is further determined whether the mode reception data is 5 or less (S94-8). This step 594-
If the judgment in step 8 is not less than 5, the process returns, and if it is less than 5, the mode execution flag is set (S94-9>, and it is determined whether the switching wheel 477 is rotating (S94-10).
The mode execution flag is a flag that is set to "1" during a process sent from the CPU 573 of the copying machine that requires a relatively long time. If the switching wheel 477 is not rotating, drive pulse counter data is loaded (S94-11). Step 594-1
After loading the drive pulse counter data in step 1, the drive pulse counter data table shown in FIG. 95 is searched from the mode reception data and the drive pulse counter data. The pulse data for moving the switching wheel 477 in this data table is set so that one pulse of the stepping motor corresponds to one degree of the switching wheel 477. Further, [a] to [d] in FIG. 95 correspond to the states (a) to d) of the switching wheel 477 shown in FIG. 96. The position of the switching wheel 477 in FIG.
Figure (b) shows the case where the original 69 is transported to the draft tray 59, Figure (c) shows the case where the copied transfer paper 37 is stored in the sheet storage bin 57, and Figure (d) shows the case where the copied paper 37 is stored in the sheet storage bin 57. The case where the transfer paper 37 is accommodated in the bruft tray 59 is shown. When the search is completed in step 594-12, the data in the data table is stored in the drive pulse memory S94-1
3) Start rotation of the switching wheel drive motor 487, which is a stepping motor, according to the 1011 Hals memory (S94-14). After that, check whether the switching wheel 477 is rotating in the forward direction (594-15), and if it is rotating in the forward direction, add 1 to the drive pulse counter and return (394-16).
If the switching wheel 477 is not rotating in the forward direction, check whether the switching wheel 477 is rotating in the reverse direction (594-17); if it is rotating in the reverse direction, calculate 1fIIi from the drive pulse counter and return. If the switching wheel 477 is rotating as determined in step 594-10, check whether the value of the drive pulse counter and the value of the drive pulse memory are equal.
94-19>, if they are not equal, the processes after step 594-15 are executed, and if they are equal, the rotation of the switching wheel 477 is stopped (S94-20), that is, the drive pulse output is turned off. Subsequently, the mode execution flag is lowered (S94-21), the drive pulse memory is cleared (S94-22), and the process returns. (8, 5 Up-down check of sheet storage bin) The sheet storage bin 57 that stores sheets such as the transfer paper 37 and the original 69 is used when receiving sheets into the sheet storage bin 57 side, when stapling sheets, and when stapling sheets. When discharging the sheet to the stack tray 67, it is necessary to move the sheet up and down. This is the finisher 11 according to this embodiment.
This is because the sheet storage bin 57 is not fixed and sheet processing is performed, but the sheet storage bin 57 is moved to perform various sheet processing as can be seen from the explanation of the mechanical configuration described above. It is. Therefore, the process related to raising and lowering the sheet storage bin 57 will be described below. FIG. 97 is a flowchart showing a check routine for raising or lowering the sheet storage bin 57 according to a command from the main body of the copying machine. In this process, first, when it is set to "1" on the copying machine 1 side, a check is made to see if the bin movement flag is set to match the bin position counter with the bin position data (597-1). If you are down, it will return, if you are standing, the CPU 573 of the copying machine will return.
The CPU 651 on the finisher 11 side receives data related to bin control transmitted from the finisher 11 side (S97-2). Note that the bin position counter is a counter that indicates the bin position currently set in the finisher 11. If the data is received, check whether the bin home request flag indicating that the seat storage bin 57 is to be moved to the home position is set (597-3). If it is, return, and if it is, the bin will be raised/lowered. It is checked whether the flag is set (S97-4). Note that the state in which the bin home request flag is set indicates the state in which the sheet storage bin 57 is returned to the home position. If it is determined in step 597-4 that the bin home request flag is set, the seat storage bin 5
597-5) Check whether the bin raise flag that raises 7 by one bin is set (597-5); if it is set, the bin is rising, so you must match it with the bin position counter that indicates the currently set bin position of finisher 11. It is compared with bin position data indicating the bin position of the finisher 11 (S97-6). If it is determined in step 397-6 that the value of the bin position counter is smaller than the value of the bin position data, the bin up flag is set and the bin down flag is lowered to lower the sheet storage bin 57 by one bin (S97
-7) Return. Further, if the value of the bin position counter is equal to or greater than the value of the bin position data in the judgment at step 597-6, both the bin up flag and the bin down flag are lowered (S97-8.59).
7-9) Return. If the bin up flag is down as determined in step 597-5, it is checked whether the bin position counter is 1 (S97-10). If the bin position counter is 1, execute steps 597-8 and 397-9 and return; if not, lower the bin up flag, set the bin down flag (S97-11), and return. do. Further, if the bin up/down flag is down as determined in step 597-4, check whether the value of the bin position counter is O (597-12), and if it is 1, set the bin up flag (S97-12). 13) Return, and if it is not 1, lower the bin lowering flag (S97-14) and return. (8, 6 Sheet storage bin lifting/lowering control) When the above check routine is completed, the seat storage bin 57 is actually
This means that the robot will move up and down. The processing procedure in this case is shown in the flowchart of FIG. 98. In this processing, first, it is determined whether or not the stable execution flag, which becomes "1" during the execution of the stapler operation including the movement of the stapler 65, is set (598-1). ), if it is set, the process returns as is; if it is not set, it is determined whether the bin home request flag is set (398-2). If the bin home request flag is off as determined in step 39B-2, it is determined whether the paper discharge OK flag is set (8983). This flag becomes "1" when the sheet is ejected using the release detection sensor 542, and becomes "O" when the sheet storage bin 57 is moved. If the discharge OK flag is down in step 598-3, the process returns; if it is up, it is determined whether the bin movement flag is up (398-4). If it is down, it returns; if it is standing, it returns the stapler 65 to its home position. Stapler home position request flag (“1” while returning to home position)
Determine whether or not (becomes) is standing (398-5)
If the roller is standing, the roller returns, and if it is lowered, the roller returns to the home position. It is determined whether the roller home return flag (which becomes "1" while returning to the home position) is set (S98-6). . If it is standing, return; if it is falling, it is further determined whether the bottle rise flag is set (398-7). If the bin up flag is down as determined in step 398-7, it is then determined whether the bin down flag is down (398-8). If the bin lowering flag is down, stop the movement of the seat storage bin 57. 398-9)
, lower the discharge OK flag and return (39B-1
0). Also, if the bin lowering flag is set in step 398-8, the lowering is performed by one bin (398-11).
, decrements the bin position counter by 1 (398-12), lowers the discharge OK flag (398-13), and returns. On the other hand, if the bin raise flag is set in step 398-7, raise the bin by one (398-14), add 1 to the bin position counter (39B-15), and discharge the paper.
Lower the flag (898-16) and return. Note that if the bin home request flag is set in step 398-2, it is difficult to determine whether the stapler home request flag is set in step 398-17.
), if it is standing, it will return as is, and if it is getting off, it will be judged whether the ochikoku home return flag is set (398-18), if the ochikoku home return flag is set, it will return and get off. If so, the bin motor 418 is turned on to the lowering side to lower the sheet storage bin 57 (398-19). Next, the sheet storage bin 57 is lowered and it is determined whether the bin home position sensor 543 is turned on (398-20). If the bin home position sensor 543 is OFF in this judgment, return; if it is ON, turn off the bin motor 418 to stop the movement of the sheet storage bin 57 (S9B-21), and reset the bin position counter) L (398 -22), further lowers the bin home request flag (398-23) and returns. (8, 7 Stapler Movement Process) The stable operation is executed as the sheet storage bin 57 moves, but in order to execute the stapling operation, it is necessary to advance the stapler 65 from its home position to the stable position. . This requires moving the stapler. FIG. 99 is a flowchart showing a procedure for moving the stapler. In this process, first, it is determined whether the stapler home request flag is set (S99).
-1), if the stapler home request flag is down in this judgment, the stable abnormality 1 flag indicating the presence or absence of staples in the stapler 65 (“l” at the staple end of the stapler,
The state (normally "0") is determined (S99-2). In this judgment, if the stable abnormality 1 flag is set, the process returns as is, and if the stable abnormality 2 flag, which indicates an abnormality in the stable motor (not shown), is set this time, it is determined. In this judgment, if the stable abnormality 2 flag is set, return is made, and if it is lowered, there is no abnormality in the stapler 65, so this time, the stapler boom position is set to 0, and the stapler position counter indicating the position of the stapler 65 is set to 01, that is, the home position. It is determined whether the stapler position counter is located (S99-4), and if the value of the counter is not 0 in this determination, it is further determined whether the value of the stapler position counter is 50 (599-5).
, 50, returns the stapler to the home position (399-6), lowers the stapler reverse flag (“1” when moving to the reverse side, normally “0”), and then moves the stapler 65 from the home position to the stable body. The stapler forward flag (
("l" when moving to the forward side, "0" when normal) is lowered (S99-7) and returns. If the value of the stapler position counter is not 50 in step 399-5, it is determined whether the stapler reverse flag and the stapler forward flag are set (S99-8). If the stapler home request flag has been dropped, the stapler home request flag is lowered (S99-9) and the process returns. Further, if the stapler position counter is 0 in the determination at step S99-4, the processing from step 599-9 onwards is executed. On the other hand, if the stapler home request flag is set in step 599-1, it is further determined whether stable home position sensor 429 is turned on (S99-10). If it is OFF in this judgment, the stapler reverse flag is set, the stapler forward flag is lowered (S99-14), and the process returns. If the above judgment is ON, lower the stapler home request flag (599-11), lower the stapler reverse flag and stapler forward flag (S99-12), reset the stapler position counter (S99-13), and then return. . (8, 8 Stable Processing) Stable processing performed as the stapler moves is performed according to the processing procedure shown in FIG. 100. In this process, first, it is determined whether or not the jogger ready flag indicating that the jigger 63 has been set at the specified jigging position is set (S100-1).If the jogger ready flag is lowered in this judgment, the process returns directly. If they are standing, check the stable abnormality 1 flag and stable abnormality 2 flag (S100-
2.5100-3), if the stable abnormality 1 flag or stable abnormality 2 flag is set, proceed to the abnormality processing routine, and if both flags are off, determine whether the seat storage bin 57 is being moved. (S 100
-4) In this judgment, if the sheet storage bin 57 is moving, the process returns, and if it is not moving, it is further judged whether the sheet discharge OK flag is set (S100-5). In this judgment, if the discharge OK flag is set, the process returns, and if it is set, the state of the drop roller return flag is judged (5100-6). In this judgment, if the stapler return flag is set, return is made, and if it is dropped, the state of the stapler home request flag is determined (5100-
7) If the stapler home request flag is set in this judgment, the process returns; if it is off, the state of the stable flag is judged (5100-8). This stable flag is a flag that executes a stable operation when "1" is transmitted from the CPU 573 on the main body side of the copying machine 1. If the stable flag is set in this judgment, return is made, and if it is lowered, it becomes "1" while the stable operation including movement of the stapler 65 is being executed. It is determined whether or not the stapling execution flag is set (S100-9). . If the stable execution flag is down in this judgment, it means that stabilization is not being executed, so the stapler forward flag is set, the stapler 65 is moved to the stable position (S100-10), and the stapler 65 is moved to the stable position (S100-10). The table is executed (S100-11). Then, a stapling execution flag is set (S100-12), and the jogger fence 47
jigging 2 (S100-13) and return. On the other hand, if it is determined in step 5100-9 that stable execution is in progress, it is further determined whether or not stable execution has ended (3100-14); if not, step 51
The processing after 00-10 is executed, and if completed, the stapler reverse flag is set and the stapler 65 is evacuated from the stapling position (3100-15). Then jog the jigger fence 472 (sloo-1

, the states of the staple abnormality 2 flag (Slot-3) and the staple flag (3101-4) are determined. and step 5IOI-2, 5IOI-3 or 510
If the flag corresponding to 8 in any of 1 to 4 is down, the process returns, and if all the relevant flags are up, it is determined whether or not the seat is stored in the seat storage bin 57 (S
lot-5). If the sheet is present in this judgment, it is further judged whether the sheet storage bin 57 is being moved (SIOI-6
). If moving is in progress, return; if not, determine the state of the stapling execution flag (SIOI
-7). If this judgment shows that the stapling execution flag is on, the process returns, and if it is off, it is judged whether the mode reception data is 6 (SIOI-8). If this judgment indicates that the mode reception data is 6, a dropping process is executed to drop the stapled sheet onto the quick-touch tray 67 (S101-9), and the process returns. On the other hand, if the drop roller home return flag is set as determined in step 5101-1, a drop roller reverse flag indicating that the drop roller moves in the direction of retraction from the sheet storage bin 57 side is set (SIOI-1

(SIOI-13). If the drop roller standby home position sensor 438 is OFF as determined in step 5IOI-13, the process returns as is, and if it is ON, the drop roller reverse flag is lowered (5101-14), and the home position state is "0".
” (SIOI-15). After that, the drop roller home return flag (during the return operation of the drop rollers) that returns the drop rollers 431, 433 to their home positions is reset (SIOI-15). ”). Return with S101-16). Also, in step 5IOI-5, the seat storage bin 57 is unloaded.
When it is determined that there is no sheet, the drop roller drive motor 441 is set to 0FFL (S103-4), and the 5-second timer is stopped and cleared (S103-5). and,
Lower the drop roller forward flag and drop roller reverse flag 5103-6.3103-7), and set the drop roller home return flag and mode end flag (S103-8.5103-9). Then 1
The second timer is stopped and cleared 5103-10), and the state of the dropping roller standby home position sensor 438 is determined (S101-10). If the return roller standby home position sensor 438 is OFF in this judgment, step S
The processing after IO1-11 is executed, and if it is ON, the processing from step 5IOI-11 to step 5101-13 is jumped and the processing after step 5101-14 is executed. FIG. 102 is a flowchart showing the processing procedure during execution of dropping stapled sheets. In this process, first, the state of the drop roller forward flag is determined (5102-1), and if this flag is off, then the state of the drop roller reverse flag is determined (5102-1).
S102-2). If the drop roller reverse flag is off in this judgment, the drop roller drive motor 441 is checked (S102-3). If the drop roller drive motor 441 is in the OFF state, the drop roller drive motor 441 is turned ON (S102-3). S102-4), returns after resetting the loop counter (5102-5). The loop counter is a counter that counts the number of protrusions and retractions of the drop roller, and performs this count six times per sheet, and only if the sheet still does not reach the sheet release sensor is a jam. On the other hand, if the drop roller drive motor 441 is ON, the drop roller forward flag is set (S102-6), and the drop roller reverse flag is lowered (3102-7), and the drop roller counter is 120 pulses or more. It is determined whether or not (S102-9). With this judgment, the drop counter increases to 1.
If it is 20 pulses or more, lower the drop roller forward flag 5102-10), further judge the state of the sheet release sensor 545 (S102-11), and if the sheet release sensor 545 is OFF in this judgment, 1 I can't decide whether the second timer has started or not.S l 0

5102-13) Return. On the other hand, if the 1 second timer has started, check if the 1 second timer is counting up.5102
-14) If the count is up, the process returns, and if the count is not up, a drop roller reverse flag is set (S102-15). Then, the drop roller counter is subtracted according to the drop roller drive pulse 5102.
-16), it is then determined whether the drop roller counter is 80 or less (S102-17). If it is greater than 80, return, and if it is less than 80, lower the dropping roller reverse flag 5102-1
8) Add 1 to the loop counter (5102-19)
. Next, it is checked whether the value of the loop counter is 6 or more (5102-20), and if it is less than 6, the 1-second timer is stopped and cleared (S102-21), and then the process returns. If it is 6 or more, the process moves to the flowchart in FIG. 103, and the drop roller forward flag and drop roller reverse flag are lowered (S103-12.510

), the 5-second timer and the 1-second timer are stopped and cleared (S103-15, 5103-16), and a sheet ejection jam flag is set (S103-17), and the process moves to the abnormality processing routine. Note that the sheet discharge jam flag is a flag that becomes 11" when the stapled sheet does not fall onto the stack tray 67. Furthermore, when it is determined that the sheet discharge sensor is ON in the step 5102-11, the flag shown in FIG. Shifts to the flowchart and determines whether the 5-second timer has started (S103-1). If not, starts the 5-second timer (S103-2) and returns; if it has started, releases the sheet. Check whether the sensor is down (S103-3). If it is down, execute the process from step 5103-4 described above, and if it is not down, check if the 5-second timer is counting up. Please judge (S103
-11). In this judgment, if the 5-second timer has not counted up, the process returns, and if it has counted up, the process from step 5IO3-12 described above is executed. Further, if it is determined in step S102-2 that the drop roller reverse flag is set, it is determined whether the sheet release sensor 545 is set (
S103-21). With this judgment, the sheet release sensor 545
If the sheet release sensor 545 has fallen, the process from step S103-4 described above is executed, and if the sheet discharge sensor 545 has not fallen, the process from step S102-16 is executed. Note that if it is determined in step 5102-1 that the drop roller forward flag is set, step 5
The processes from 102-6 onwards are executed.

[9. ill during document processing Up to now, the control of post-processing of the transfer paper 37 and the document 69 has been described. Therefore, document processing control for feeding and processing the document 69 according to a plurality of input mode settings will now be described in detail. Incidentally, the timing of cent, paper feeding, ejection, etc. of the original 69 is based on the timing chart shown in FIG. 104. (9,1 Initial processing) The initial processing includes: ■Door oven check of the document reversing unit, ■Optional connection check for the document conveyance unit, ■Bin home request processing in the multi-stage unit, ■Conveyance section (pressure plate) of the document conveyance unit. There is a lift-up check and an initial jam check. (2) Door open check of document reversing unit 52 First, a check is made regarding the opening of the door in the document feeder, that is, in this embodiment, the document transport system 9. FIG. 105 is a flowchart showing the door oven check processing procedure. In this process, the document reversing unit 52 is used as the document transport unit).
51 (S105-1), the state of the document reversing unit connection flag (“1” if connected, “0” if not connected) is determined. In this judgment, if the document reversing unit connection flag is not set, the process returns as is, and if it is, the document reversing unit 51
determines whether the door is open, and if it is open, lowers the document reversal jam flag 5105-3), sets the document reverse unit door oven flag (S105-4),
Furthermore, the above-mentioned document reversal jam flag and document reversal unit door oven flag are set to the CPU on the copying machine main body side.
573 as serial data and return. Further, if the document reversing unit door is closed as determined in step 5105-2, the document reversing unit door oven flag is lowered (S105-6) and this flag is set to
Send to PU573 and return. The document reversing unit jam flag is a flag for the first document entry detection sensor 370 and the second document entry detection sensor 36B of the document reversing unit 52, and the document reversing unit door oven flag is a flag for the document reversing unit 52. This flag is “1” when the door is open and “0” when the door is closed. ■ Check the optional connection to the document feed unit 51 In the second embodiment, the document stack tray 353, multi-tier unit 50, etc. are connected to the document feed unit 51 as an option. Check whether the device is connected. This processing procedure is shown in the flowchart of FIG. 106. In this process, initial settings are performed by first clearing the boat mode and RAM, and executing an initial setting subroutine that resets flags and counters (S106-1).
). Next, it is determined whether the document reversing unit 52 is connected (S106-2). This determination is made by using the input port of the gate array 605 of the document transport unit 51 and looking at the level of the input port. In this case, if it is connected, it will be “L” level.If it is not connected, it will be “L” level.
Then, if the determination in step 5106-2 is that the document reversing unit 52 is connected, the document reversing unit connection flag is set (S106-2).
3), if it is not connected, lowers the document reversing unit connection flag 5106-4), and further determines whether the multi-stage unit 50 is connected (S1
06-5). The connection of this multi-stage unit 50 is also performed in the same manner as the connection of the document reversing unit 52. Based on the judgment in step 5106-5, the multi-stage unit 50
is connected, set the multi-stage unit connection flag (5
106-6), if not connected, lowers the multi-stage unit connection flag (S106-7) and transmits the reversing unit connection flag and the multi-stage unit connection flag as serial data to the CPU 573 side of the main body of the copying machine (S106-7).
3106-8). The multi-stage unit/node connection flag indicates the connection state of the multi-stage unit 50 to the document transport unit 51, and is "1" if the multi-stage unit 50 is connected to the document transport unit 51, and "1" if the multi-stage unit 50 is not connected.
0". It goes without saying that (in this embodiment, the multi-stage ADF 49 has a multi-stage unit 50 and a document transport unit 51).
It consists of When the processing in step 5106-8 is completed, it is checked whether there is a transmission error (5106-9), and if there is no error, the process returns; if there is an error, the transmission error processing routine is executed (S106-10) and the process returns. ■ Bin home request processing in multi-stage unit This process is performed by the document bin 201 for feeding the document 69.
This is to return the camera to its home position and determine its initial position. This processing procedure is shown in the flowchart of FIG. In this process, first, the state of the bin home request flag is determined (S107-1). The bin home request flag means that when the bin home request flag on the copying machine main body side becomes '1'', the CPU 6 on the document transport unit 51 side
01 receives this and sets the bin home request flag'
1", that is, sets the bin home request flag and moves the document bin 201 to the home position.
When the document bin 201 moves to the home position, the flag is lowered and transmitted to the CPU 573 of the copying machine main body. If the bin home request flag is set in step 5107-1, the bottom plate home position sensor 25
1 is determined (S107-2). In this judgment, if the bottom plate home position sensor 251 is OFF, the bottom plate raising motor 241 is reversely rotated, the bottom plate 211 is lowered (S107-3), and the return is made, and the bottom plate home position sensor 251 is ON, that is, the bottom plate 211 is at the home position. If it has returned to , turn off the bottom plate lift motor 241.
to stop the bottom plate 211 at the home position (
S107-4). Next, the leading edge detection sensor 243 determines whether there is any remaining paper (3107-5), and if there is any remaining paper, a paper jam flag is set in the flowchart of FIG. 108 (310B-15), and step 5i08 described below is performed.
-1 and subsequent routines are executed, and if the remaining paper is removed, the registration detection sensor 245 determines whether there is any more remaining paper (5107-6). If there is any remaining paper in this judgment, step 3108-1 is performed in the flowchart of FIG. 108.
Execute the routine from step 5, and if there is no remaining paper, check the status of the bin home sensor 222 (5107-7), and if the pin home sensor 222 is ON, stop the reverse rotation of the wheel motor 231 and replace the original. The bin 201 is made to stand by at the home position (S107-8). Then, set the bin switching solenoid 240 to 0FFL (5107
-9) Lower the paper jam flag of the document transport unit 51 (5107-10). This paper feed jam flag is a jam flag for the tip edge detection sensor 243 and the registration detection sensor 245, and is normally 1
When the paper jam flag is lowered in step 3107-10, the bin counter (DF upper pin counter) of the document bin 201 and the bin counter memory (DF pin counter memory) are
(5107-11). The DF upper pin counter is for each document bin 20 of the aforementioned five-stage multi-stage unit 50.
This is a counter that indicates the position of 1, and the count has the following meaning. All 0:5 bins are located at the lower bin home position. 1: Job processing for the first or topmost bin, and processing for moving that bin. 2: When processing a job in the second bin and moving that bin. 3: Job processing for the third bin and movement processing for that bin. 4: Job processing for the fourth bin and movement processing for that bin. 5: Job processing for the fifth or bottom bin, and processing for moving that bin. Further, the DF pin counter memory is used for the DF pin counter during interrupt processing and reservation mode processing. After completing the process in step 3107-11, the bin up flag is set (S107-12), the bin home request flag is lowered (S107-13), and the initial jam check subroutine is executed (S107).
-14) Return. On the other hand, in step 3107-7, the bin home sensor 222
When it is determined that the wheel motor 2 is OFF, the wheel motor 2
31 rotation is checked (S107-15). If the wheel motor 231 is rotating in the reverse direction as determined in step 5107-15, the process returns; if it is rotating in the forward direction, the state of the wheel standby home position sensor 253 is checked (S107-16). 253 is OFF, the wheel motor 231 is rotated forward to move the Geneva wheel 207 to the wheel standby home position (S107-1
7) Return, and if ON, the forward rotation of the wheel motor 231 is stopped, and the Geneva wheel 207 is stopped at the wheel standby home position (S107-18). After that, turn on the bin switching solenoid (5107-1
9) The wheel motor 231 is reversely rotated to lower the document bin 201 and return. (2) Lift-up check and initial jam check of the transport section of the document transport unit FIG. 108 is a flowchart showing the processing procedure for lift-up check and initial jam check of the transport section of the document transport unit. In this check routine, first, it is determined whether the conveyance section of the document conveyance unit (hereinafter also referred to as DF) is lifted up, in other words, whether the pressure plate 288 is opened (310B-1), and if it is not lifted up, the DF Lowering the lift-up flag 31
08-2) Check whether there is any remaining paper using the paper discharge sensors 321 and 322 (S108-3). If the original 69 remains at the sensor position, the reversal jam flag (
(normally “0”, “1” when jammed) (5108-4)
, if no document 69 remains, the first and second entry detection sensors 370.36B determine whether or not the document 69 remains (3108-5). If the pressure plate 288 is lifted up as determined in step 5108-1, the reverse jam flag is lowered 3.
108-108-6), ADF lift up flag (
If the pressure plate of the DF is lifted, set it to "l"; if the pressure plate is closed, set it to "0") (3108-7), and then set the document transport motor 323 and reversing solenoid 316 to zero.
Clear FFL, size data and counters (5
108-8) Proceed to step 3108-5. In step 3108-5, if the original 69 remains on the first or second original entry sensor 370, 368, a document reversal jam flag is set (3108-9); , 322 to determine whether or not the paper is ejected. Original discharge sensor 321, 3
If 22 is ON, the document 69 remains in the paper output section, so the document reversal jam flag is set (8108-11).
, if it is OFF, the original stack tray 38
Determine whether manuscript 69 exists in 2 (3108-
12). If there is a document 69, it is detected by the stack tray paper end sensor 376, and a remaining paper check flag is set (5108-
13) If not, just move each flag to C on the copier's main body.
It transmits to PU573 and returns "' (3108-14). Also, step 5 of the flowchart in FIG. 107 described above
If the initial jam check routine has proceeded from step 107-5 or step 5107-6,
After setting the paper jam flag (3108-15), the process from step 8108-1 onwards is executed. (9. Movement of 2 original document bins) The selection and movement of 5 original document bins 201 is executed in response to the job determined by the copying machine main body. The processes related to the selection and movement of the document bin 201 include (1) multi-stage unit bin number data input process, (2) bin movement process based on data received from the copying machine main body, (2) bin raising process, and (2) bin lowering process. Each case will be explained in detail below. (2) Bin number data input process for multi-stage unit FIG. 109 is a flowchart showing the processing procedure for inputting bin number data for the multi-stage unit. In this process, first, in order to check the connection state of the multi-stage unit 50, the state of the multi-stage unit connection flag is determined.
109-1) If the multi-stage unit connection flag is down, output dummy data and return as is; if it is up, decode the data sent from the CPU 573 of the copying machine main body (S109-2). When the data is decoded, it is checked whether the copy mode received data is O (3109-3). If it is 0, return as is, and if it is not 0, check whether the copy mode received data is less than or equal to 5 (S109-4).If it is greater than 5, return, and if it is less than or equal to 5, the copy mode Set the document bin 201 that matches the received data in the paper feed home position (5
109-5) Return. Note that the above step 510
The number 5 in the copy mode received data, which is the criterion for determination 9-4, comes from the fact that the multi-stage unit 50 has five stages. Therefore, it goes without saying that the results will be different if the number of stages of the multi-stage ADF 49 is different. (2) Bin movement processing based on data received from the copying machine main body FIG. 110 is a flowchart showing the processing procedure for bin movement based on data received from the copying machine main body. In this process, first check the status of the bin set end flag (
Silo-1). What is the bin set end flag? The document bin 20 is moved from the standby home position to the paper feed home position.
This flag indicates whether or not 1 has been written. If it is set, the flag is 1, and if it is not, it is 0. If the Vincent end flag is set in step 5ilo-1, the document is placed in the document bin 201. Since it is set at the paper feed home position, it returns as it is, and when it is down, it stores the content of the mode reception data, that is, the number of bins, in the request bin memory (SIIO-2).Then, it checks the state of the bin home request flag. 5II
O-3) If the bin home request flag is set, the vehicle returns as is, and if the vehicle is alighted, the state of the wheel standby home position sensor 257 is checked (511).
0-4). Note that the bin home request flag mentioned above means that when the bin home request flag on the copying machine main body side becomes "1", the DF side receives it and sets the bin home request flag on the DF side to 611 to send the document to the home positive run of the document bin 201. This is a flag that causes a return to be executed. Geneva wheel 20 as determined in step 5IIO-4 above.
If 7 is not located in the standby home position, lower the bin home request flag (3110-5).
Returning, it is determined whether the value of the pin counter on the DF is equal to the value of the request bin memory (Silo-6). If the two are equal in this judgment, execute a subroutine to move the document bin 201 to the paper feeding position, that is, the paper feeding home position (SLio-10), and return; if they are not equal, the value of the pin counter on the DF is requested. Determine whether the value is larger than the bin memory value (SIL
O-7). If the value of the DF upper pin counter is less than or equal to the value of the request bin memory, the DF bin raising processing subroutine described later is executed to raise the document bin 201 (Si
lo-8), if the value of the DF upper pin counter is larger than the value of the request bin memory, execute the DF bin lowering processing subroutine described later to lower the document bin 201 (
S110-9) Return after executing the subroutine of step 5ilo-10. (2) Bottle Lifting Process The content of the bin lifting process subroutine in step 5IIO-8 is as shown in the flowchart shown in FIG. 111. In this process, first, it is checked whether the value of the DF pin counter and the number of bins stored in the request bin memory are equal (S111-1). If the two are equal, set the standby set end flag and return (Sill
-2). This standby cent end flag is the CPU 5 on the copying machine main body side.
The document bin 201 has been moved by the number of bins sent from 73 and has been designated as the standby home position sensor 257.
This flag becomes "l" when set. On the other hand, if it is determined in step 3111-1 that the value of the DF upper pin counter is not equal to the number of bins stored in the request bin memory, the wheel motor 231 is rotated forward to raise the document bin 201 (Sllll- 3), Timers 1 and 2 have started, but I can't confirm.Sill
-4) If timers 1 and 2 have not started, start both timers (Sll15) and return. Also, if timer 1.2 has started, check whether timer 1 has counted up or not (Sl 1l-6); if it has not counted up, return; if it has counted up, the status of the standby home position sensor 257. (Sill-7>. If the standby home position sensor 257 is ON in the second check, stop the forward rotation of the wheel motor 231 and stop it at the standby home position (SLll-8). Add 1 to the pin counter (5111-9), stop and clear timers 1 and 2 (Sill-10), and return. On the other hand, if the standby home position sensor 257 is in the OFF state in the check at step 5ill-7, it is checked whether the timer 2 is counting up. If the count is not up, it returns as is, and if the count is up, the wheel motor 23

sllll-12). Next, after stopping the timers 1 and 2 and clearing them (5ill-13), the bin abnormality flag is set (Sill-14) and the process proceeds to the abnormality processing routine. The bin abnormality flag is "1" if there is an abnormality in the moving operation of the document bin 201, and is normally "0". (2) Bin Lowering Process The contents of the DF bin lowering process subroutine in step 5110-9 are as shown in the flow chart shown in FIG. 112. In this process, first the bin switching solenoid 24
0NL (S112-1), it is determined whether the value of the DF upper pin counter and the value of the request bin memory are equal (
S112-2). If the two values are equal in this judgment, the standby set end flag is set (S112-3) and the process returns; if the two values are not equal, the wheel motor 231 is reversely rotated to lower the document bin 201 (S112-3).
4). Next, it is checked whether timers 1 and 2 have started (5112-5), and if not, both timers 1 and 2 are started (3112-6) and the process returns. If timer 1.2 has started, check whether timer l has counted up (5112-7), and if it is not counting up, return, and if it has counted up, check the state of standby home position sensor 257. Check (S112-8). This step 311

If is ON, reverse rotation of the wheel motor 231 is stopped, and the document bin 201 is stopped at the standby home position (S112-9). Then, the DF upper pin counter is decremented by 1 (5112-10), the timer 1°2 is stopped and cleared (S112-11), and the process returns. On the other hand, if the standby home position sensor 257 is OFF in the check at step 5112-8, it is checked whether the timer 2 is counting up (S11
2-12). If the timer 2 has not counted up, the process returns, and if it has counted up, the reverse rotation of the wheel motor 231 is stopped and the movement of the document bin 201 is stopped (S112-13). Then timer 1
．． 2 is stopped and cleared (5112-14), the bin abnormality flag is set, and the process proceeds to the abnormality processing routine. (9, 3 Original Bin Paper Feeding Position Set) In order to process the original stored in the original bin 201 according to the input mode, the original bin 201 containing the original to be processed in that mode must be set. It is necessary to move the document to the document feeding position and set it. The processing procedure of this process is shown in the flowcharts of FIGS. 113 and 114. In the processing procedure shown in FIG. 113, first, it is determined whether the standby cent end flag is set (S113-1
), if the standby set end flag is down in this judgment, it returns as is, and if it is up, the bin switching solenoid 2 is activated.
40 is checked (S113-2). and,
If the bin switching solenoid 240 is in the ON state, the bin switching solenoid is turned OFF (S113-3) and the process returns. Bin switching solenoid 240 is already OFF
If so, the wheel motor 231 is reversely rotated to move the document bin 201 to the paper feeding position (S113-4);
Determine whether timer 3 has started (S11
3-5). If timer 3 has not started, it is started (S113-6) and the process returns; if it has started, it is checked whether or not timer 3 is performing count amplification (S113-7). This timer 3
If the count is up, the reverse rotation of the wheel motor 231 is stopped (5113-8), and after stopping and clearing the timer 3 (S113-9), the bin abnormality flag is set (5113-8).
5113-10) Return. On the other hand, if the timer 3 has not counted up in the check at step 5113-7, the state of the paper feed home position sensor 259 is checked (S113-11). This check turns off the paper feed home position sensor 259.
If it is F, the process returns; if it is ON, the reverse rotation of the wheel motor 231 is stopped and the document bin 201 is stopped at the paper feeding home position (S113-12). Then,
After stopping and clearing the timer 3 5113-13), lowering the standby set end flag 3113-14), and setting the bin set end flag (S113-15), return. In the processing procedure shown in FIG. 114, the process is started after checking whether there is a document jam (5114-
1). If it is determined in this step 3114-1 that the document 69 is jammed, the process returns directly, and if there is no jam, the status of the bin set end flag is checked.
2) If the bin set end flag is down, return; if it is up, store the data of the DF pin counter in the bin position data of the multistage unit 50 (S114-3);
Then, the state of the bottom plate upper limit (rise detection) sensor 263 is checked (S114-4). If the lift detection sensor 263 is OFF in this check, the bottom plate lift motor 241 is rotated in the forward direction to lift the bottom plate 211 (S114-5), and the process returns; if the rise detection sensor 263 is ON, the bottom plate lift motor 241 is stopped. Stop the bottom plate 211 (S11
4-6) 0 Next, check the state of the document cent detection sensor 249 (5114-7), and if the document 69 is detected, set the document set flag (S114-8), and if the document 69 is not detected, the document Lower the set flag (
S114-9) Each flag is sent to the CPU of the copying machine.
573 side, 3114-10>, and return. (9,4 Feed-in Process) The feed-in process is a process in which a document feed signal is input from the CPU 573 side of the copying machine main body and the conveyance of the document 69 to the document conveyance unit 51 side is started. Specifically, the process is executed according to the flowchart shown in FIG. 115. In this process, first, the state of the paper jam flag is checked (S115-1), and if the paper jam flag is set, the document 69 is jammed in the multi-stage uni-gutter 50, so the paper jam flag is flagged. is sent to the CPU 573 side of the copying machine main body (S1152), and after executing the paper feed jam check subroutine shown in the flowchart of FIG. 116 (described later) (S115-3), the process returns. On the other hand, if the paper jam flag is down, it means that no jam has occurred, and the state of the document center flag is then checked (S115-4). The document set flag is a flag indicating whether or not there is a document 69 on the document bin 201, and is "1" if there is a document, and "0" if there is not. If the document set flag is down at the check in step 5115-4, the process returns; if it is up, the CPU 5 of the copying machine
Decode the data sent from the 73 side (S115
-5). Further, a document feed flag is transmitted from the CPU 573 side, and it is checked whether the document feed flag is set (5115-6). If the document feed flag is down at the check in step 5115-6, the process returns; if it is up, the state of the document duplex flag is checked (S115-6). If this double-sided document flag is set, it is a double-sided document, so execute the subroutine for double-sided document feed processing (5115-8); if it is off, it is a single-sided document, so the subroutine for single-sided document feed processing is executed. After executing any subroutine (S115-9), the state of the paper jam flag is checked (5115-10). If the paper jam flag is off during this check, set the copy start flag (5
115-11), the copy start flag and original size data were sent to the CPU 573 side of the copying machine main body (5
115-12) and then return. On the other hand, if the paper jam flag is set in step Sl 15-10, step 5115-2 and step 5L1
Execute the process 5-3 and return. (9, 5 Paper Feed Jam Check Process) This process is a process for retracting the document bin 201 in order to improve the removal of the jammed paper when a jam occurs during the feed-in of the document 69. The flowchart in FIG. 116 shows the specific processing procedure. In this process, first, lift-up of the document transport unit 51 is checked (S116-1). If the lift is up, set the ADF lift up flag (S116
-2) Check whether there is paper at the registration detection sensor 245 and leading edge detection sensor 243 positions (S11
6-3). If there is paper, the process returns; if there is no paper, a paper jam removal flag is set (S116-4) and the process returns. On the other hand, if it is determined in step 3116-1 that the DF is not in the DF lift-up state, the ADF lift-up flag is lowered (5116-5), and the state of the document set flag is checked (S116-6). If the document top flag is set during this check, the bottom plate lift motor 2
41 in the opposite direction to lower the bottom plate (S 116-7)
, if the original cent flag is down, the state of the bottom plate home position sensor 251 is checked (S1
16-8). When the bottom plate home position sensor 251 is turned ON by this check, the bottom plate lifting motor 241 is stopped to stop the bottom plate 211 (Sl16-9), and the wheel motor 231 is rotated forward (5116-10). As a result, the document bin 201 is moved to the standby home position, and the document set flag is lowered (S116-11). Then, the process waits until the standby home position sensor 253 turns on, and when it turns on, the forward rotation of the wheel motor 231 is stopped to stop the document bin 201 at the standby home position (S116-12). After that, lower the bin set end flag 5116-1

16-16), when the paper jam removal flag is set, check the state of the paper jam removal flag (S116-17), and when the paper jam removal flag is set, the paper jam removal flag (S1
16-18), paper jam removal flag (S116-19)
) and paper jam bin flag (S116-20) were lowered in order, and an initial jam check was performed (S11
6-21) Then return. (9, 6 Document discharge processing) The document 69 that has been exposed for copying is discharged to any of the document discharge tray 285, document stack tray 382, draft tray 59, and sheet storage bin 57, and is subjected to predetermined processing. is executed. For this process, ■Document ejection processing! , ■Document ejection processing, ■Initial processing, and ■Switching motor drive processing. Note that the two flowcharts shown in FIGS. 117 and 118, which will be described later, are for determining the destination (discharge method) of the document 69 based on code data from the copying machine, and the document discharge process. 127 and 129 are the processes for selecting the four discharge methods, and the document discharge process {circle around (2)} is the process for selecting the three switching positions ■ in FIG. 22. This will be explained in detail below. (1) Original discharge processing I This processing procedure is specifically shown in the flowchart of FIG. 117. In this process, first check if the paper is being ejected.
7-1>, CPU5 of the copying machine main body if paper ejection processing is not in progress
5117-2), and if the paper ejection process is in progress, it checks whether the document ejection flag is set (S117-3). In this step 5117-3, the document ejection flag is set. If it is down, return; if it is up, check whether the copy mode received data is between 6 and 9 (5117-4);
The received data in step S117-4 is for checking whether the document stack tray is in the ejection mode. If it is determined in step Sl 17-4 that the copy mode reception data is between 6 and 9, it is further checked whether the document reversing unit connection flag is set.
117-5), if the user is standing, that is, if the document reversing unit 52 is connected, it is checked whether the door of the document reversing unit 52 is open (S117-6). If it is confirmed that the door is closed, step 5117
-7 executes the document ejection processing subroutine, and also checks whether the copy mode received data is 6 or 9 (5117-8), and if it is not 6 or 9, the original 6
A subroutine for discharging 9 to the document stack tray 382 side is executed (5117-9), and if it is 6 or 9, a subroutine for discharging the document to the document stack tray 382 after reversal processing is executed (S117-10) and the process returns. Further, when the copy mode reception data is not between 6 and 9 in step Sl 17-4, when the document reversing unit connection flag is off in step 5117-5, and when the door of the document reversing unit 52 is open, The subroutine for document discharge processing in step 5117-11 is executed, and after the document 69 is discharged to the document discharge tray 285 on the DF (5117-12), the process returns. Note that step 5117-7 and step S117-
The subroutine 11 is a process based on the flowcharts of FIGS. 61 to 65 described above, and includes step 511.
The subroutine 7-9 is a process based on the flowchart in FIG. 105, the subroutine 5117-10 is a process based on the flowchart in FIG. 106, and the subroutine 5117-12 is a process based on the flowchart in FIG. 108. It is. These processes have already been described in detail in the above-mentioned (2nd and 3rd document reversing section). ■ Original discharge processing ■ This processing procedure is shown in the flowchart of FIG. 118. In this process, it is first checked whether the copy mode received data is between 6 and 9 (3118-1). If it is not between 6 and 9, return, and if it is between 6 and 9, check whether the document stacking unit connection flag is set (511B-2), and if this document reversing unit connection flag is set. That is, when it is confirmed that the original reversing unit 52 is connected, it is checked whether the copy mode reception data are 6 and 7 (5118-3). Therefore, if the copy mode received data is 6 and 7, the subroutine for switching motor drive processing is executed (S11B-4) and the process returns. This subroutine sets the switching motor back flag, stores 20 in the step angle memory, and drives the switching stepping motor 377 by 120 steps. On the other hand, if the copy mode received data is not 6 or 7, the reversing unit switching home request flag, which is a flag for executing the process shown in FIG. 119, is set (311
8-5) Return. ■ The switching of the initial processing document reversing unit 351 is performed by a stepping motor, and the position when the switching home position sensor 378 is turned on is set as the home position. Step (Figure 23) (3) Foot
Switching processing is performed in three patterns of 20 steps (FIG. 24) on the word side. The document transfer section 351 of the document reversing unit 52 can be driven in forward and reverse directions. (1) Forward rotation: Linear speed equivalent to that of the DF conveyor belt 53, etc. (2) Reverse rotation: Sheet on the copying machine 1 side There are two patterns: a discharge linear velocity and a linear velocity equivalent to the sheet discharge linear velocity of the finisher 11. In this case, forward rotation is the direction of rotation in which the document is transported from the paper discharge section side of the DF to the document stack tray 382 side, and reverse rotation is the rotation direction in which the document is transported from the document stack tray 382 side to the reversing unit switching mechanism and further to the finisher 11 side. It is the direction. This initial process is a process in which the switching mechanism is set at the home position and the document transport section 351 is not moved. This processing procedure is shown in the flowchart of FIG. In this process, first, check whether the reversing unit switching home request flag is set.
1) If the user is not standing, return; if the user is standing, check whether the switching home position sensor 378 is turned on (S119-2). If ON, lower the switching motor forward flag and back flag (5119-3), reset the step angle counter (S119-4), lower the reversing unit switching home request flag (S119-5), and then return. . On the other hand, if the switching home position sensor 378 is OFF in step 3119-2, it is checked whether either the switching motor forward flag or the back flag is set (<5119-6). If either flag is down, reset the step angle counter (5119-7), set the switching motor forward flag (5119-8), and set the switching (stepping, knocking) motor 3.
77 to the 1 step forward (forward rotation) side (
Si19-9). Next, the step angle counter is incremented by 1 (5119-10), and when the count value of the step angle counter becomes larger than 50 (S119-11), the switching motor forward flag is lowered (5119-12), and the steering knob angle counter is reset. Then (S119-13) the switching motor bank flag is set (S119-14) and the process returns. Further, when it is determined in step 5119-6 that either the switching motor forward flag or the bank flag is set, the state of the switching motor back flag is checked (5119-15). If the switching motor back flag is down, the processing from step 5119-8 onward is executed, and if it is up, the switching stepping motor 37
7 to the 1 step bank (reverse rotation) side (S11
9-16). Then, the step angle counter is further incremented by 1 (5119-17), and the step angle counter becomes 106.
If the above is reached (S119-18), the switching motor back flag is lowered (5119-19), the step angle counter is reset (S119-20), and then the process moves to the abnormality handling routine. (2) Switching Motor Driving Process The switching motor of the document reversing unit 351, that is, the switching stepping motor 377 is driven according to the processing procedure shown in the flowchart of FIG. 120. In this process, first, it is checked whether the step angle counter has been reset (5120-1), and if it has not been reset, a reversing unit switching home request flag is set (S120-2) and the process returns. If it has been reset, check whether the reversing unit switching home request flag is set (5120-3);
If the reversing unit switching home request flag is set, return, and if the reversing unit switching home request flag is set, check whether the switching motor forward flag and back flag are set (
S120-4). If these flags are set, it is further checked whether the switching motor back flag is set (S120-5), and if it is set, the switching stepping motor 377 is driven one step back (S120-6). If S1 is on, the switching stepping motor 377 is driven one step forward (S1
20-7), increment the step angle counter by 1 (S1
20-8), then check whether the step angle memory and step angle counter are equal 5120-9), and if they are equal, set the switching motor forward flag and switching motor back flag 5120-10, 5120 respectively.
-11), set the switching stepping motor 377 to 0FF (
3120-12) and return. In addition, step 5
If the switching motor forward flag and bank flag are down in step 120-4, and step 5120-9
If the step angle memory and step angle counter are not equal, the process returns directly. (9, 7 Original stack unit processing) This process involves transporting the original 69 to the original stacking tray 382 and moving the original 69 on the original stacking tray 382 to the roller 381.
This is the process of arranging them. Specifically, this is performed according to the processing procedure shown in the flowcharts of FIGS. 121 and 122. In the process shown in FIG. 121, first, the original stack tray 3
5121-1 to check whether the original was ejected to 82.
), when it is ejected, the switching stepping motor 377 is turned on to set the switching member 365 to the home position (S121-2). This is the state shown in FIG. 22 mentioned above. When the switching member 365 is set to the home position, the state of the first entry detection sensor 370 is checked (5121-3), and the state of the first entry detection sensor 370 is checked.
If the entry detection sensor 370 is ON, that is, the document 69 has been conveyed from above the contact glass 17 and has reached the first entry detection sensor position, the switching solenoid 380 is turned OFF.
(S121-4). Next, if timer 2, which is a jam check timer for the first intrusion detection sensor 370 and the second intrusion detection sensor 368, has started (Si20
-5: Y) Wait until timer 2 count amplifier (S12
1-6), if timer 2 has not started, the DF paper discharge sensors 321 and 322 and the first entry detection sensor 37
The timer 1, which is a non-feed jam check timer between 0, is stopped and cleared (312m-7), the timer 2 is started (S12i8), and the timer waits until the count amplifier of the timer 2 (3121-6). If the count amplifier of timer 2 has finished in this step 5121-6, timer 2 is stopped and cleared (5121-10), and a document reversal jam flag is set (5121-11).
5121-12) The process moves to the jam processing routine. If timer 2 has not counted up, check the state of the second intrusion detection sensor 368 (5121-9), and if it is OFF, return and turn ON.
If so, stop timer 2 and clear it 5121-13)
do. Next, the energization of the calling solenoid 386 is stopped, and timer 3, which is a jam check timer, is started (S121-14) and the process returns. On the other hand, when step 7 block 5121-3 determines that the first entry detection sensor 370 is OFF, check whether timer 1 has started (5121-15), and if it has not started, start it (S121-16). ) to return. If it has started, wait until timer 1 counts up (S121-17), and if it counts up, stop timer 1.2 and clear it.S121-
18), set the document discharge jam flag (S121-1
9) A flag is sent to the CPU 573 side of the copying machine main body (S121-12) and the process moves to the jam processing routine. In addition, in the process shown in FIG.
), if it is ON, as shown in the timing chart of FIG. 135, the counter of the 0.3 second timer that counts the processing time for moving the document 69 is checked (5122-2). Then, when the count has increased, the 0.3 second timer is stopped to clear the count (5122-3), the document loading roller drive solenoid 383 is turned off (S122-4), and the process returns. In contrast, the document loading roller drive solenoid 383 is turned off.
If F, check the state of timer 3 and select 5L2.
2-5) If timer 3 is ON, check the count amplifier of timer 3 (3122-6). If the count has not increased, it is checked whether the original discharge sensor 379 of the original stack unit has risen as shown in FIG. 135 (S122-7). If it has started up, timer 3 is stopped and cleared (S122-8), and then the process returns. If the original ejection sensor 379 of the stack tray section 677 has not been raised, a check is made to see if the document ejection sensor 379 of the stack tray section 677 has been lowered (S122-9). If it has not fallen down, it returns, and if it has fallen down, it starts a 0.2 second timer which is a delay timer until the ejected document 69 falls onto the document stack tray 382, as shown in FIG. 3122-10), add 1 to the ejected original document number counter (SL22-11)
Return. Further, when it is determined that the timer 3 is counting up in step S122-6, the timer 3 is stopped and cleared (5122-17), and a document reversal jam flag is set (S122-18) on the CPU 573 side of the copying machine main body. After transmitting the flag to (S122-19), the process returns. Further, when it is determined in step 3122-5 that timer 3 is OFF, the 0.2 second timer is set to 0N (S1
22-12), wait until the 0.2 second timer counts up (5122-13), and when it counts up, stop the 0.2 second timer and clear it.5122-1
4) Start a 0.3 second timer (S122-
15). Then, the document loading roller drive solenoid 383 is turned ON and returned. In addition, the document loading roller 381
It goes without saying that 0N10FF may be performed multiple times for one ejected document. (9, 8 Refeeding Process) This process is a process for feeding the original 69 to the finisher 11 side, and the sheet processing after the original 69 is fed to the finisher 11 is the same as that for the transfer paper 37. . Specifically, the paper refeeding process is performed according to the processing procedure shown in the flowchart of FIG. 123. In this process, first, the state of the transport jam flag is checked in order to know the transport state of the document 69 (5123-1).
. If the conveyance jam flag is set, the process moves to the abnormality handling routine, and if the document reversing unit 52 is off, it is checked whether the door of the document reversing unit 52 is open (5123-2), and if it is open, the process moves to the abnormality handling routine. If it is closed, check whether the document reversal jam flag is set (S
123-3). If the document reversal jam flag is set,
The process moves to the abnormality processing routine, and if the document feeding start flag is off, the status of the document feeding start flag is checked (S123-4). If the document feeding start flag is not set, that is, document feeding has not started, the process returns; if the document feeding start flag is set, in other words, if document feeding has already started, The state of the document feeding flag is checked (S123-5). If the document feeding flag is set, the document 69 is being fed at that point, so it is time to repeat the feeding.S123-6) Check the timing. When this happens, there is a document 69 on the document stack tray 382, but BI recognizes it as 4 (5123-7). If there is no original document 69 on the original stack tray 382, the document feeding flag is lowered and the process returns. Original stack tray 3
If there is a document 69 in 82, turn on the paper refeeding franc located coaxially behind the separation roller 390 shown in FIG.
23-18), the state of the second entry detection sensor 368 is checked (S123-19). This check turns on the second entry detection sensor 368.
When the paper refeed clutch is set to 0FFL (S123-

Figures (a) to d) are timing charts showing the flow of the document 69 and the operation timings of the turn roller, conveyance heald, first and second paper ejection sensors, and reversing solenoids due to differences in conveyance patterns. al or shuku d)
The patterns correspond to each of the explanatory diagrams specifically showing the flow of a document in FIGS. 129(a) to 129(dl). First, the configuration of each part such as the turn roller will be explained with reference to FIG. 128, which is a diagram of the main part configuration of FIG. 2 mentioned above. Although this partially overlaps with the explanation regarding FIG. 2, a driven roller 305 for tensioning and driving the conveyance heald 53 is disposed on the finisher side of the contact glass 17, that is, on the left side in the figure, and further to the left side thereof. Turn roller 31
5 is located. First and second driven rollers 324 and 326 are in rolling contact with this turn roller 315, and the finial shaft 11 of both rollers 324 and 326 is in rolling contact with the turn roller 315.
First and second paper ejection sensors 32 are installed on the side transport paths, respectively.
1,322 are provided. Further, the conveyance path 3 formed on the outer periphery of the turn roller 315
11 in the clockwise direction.
18a, 318b, and 318C are provided. These direction switching pawls 318a, 318b, and 318C are oscillated by a reversing solenoid 316 to switch the direction in which the document 69 is conveyed. Four conveyance directions are set for the document 69 as described below, and these directions are switched by the first and second paper ejection sensors 321 and 32.
In step 2, the process is executed based on the rise during document conveyance, that is, the arrival of the document 69, and the fall, that is, the timing when the document 69 leaves the sensor position. FIG. 127(a) shows a document 69 placed on the document stack tray 38.
2 shows the timing of conveyance. In this case, the turn roller 315 and the conveyor belt 53 start forward rotation (F) at the same timing. On the other hand, the reversing solenoid 316 is in the OFF state, and the first direction switching pawl 318a maintains the state indicated by the dashed line. The first paper discharge sensor 321 detects the document 69, and when the document 69 passes through the detection position of the first paper discharge sensor 321 and the output of the sensor falls, at this timing the turn roller 315 and the conveyor belt 53 are turned off at the same time. That is, the original 69 is conveyed from the conveyor belt 53 to the original stack tray 382 via the turn roller 315 as shown by the arrow in FIG. 129(a). Note that the time indicated by the symbol A in the figure is the time for the original 69 to pass through the first discharge detection sensor 321, and it naturally varies depending on the size of the original 69. FIG. 127(b) shows the timing when the original 69 is conveyed to the original stack tray 382 after being reversed. In this case, the turn roller 315 and the conveyor belt 5
3 starts forward rotation (F) at the same timing, and at the same time, the reversing solenoid 316 is turned on. As a result, the first, second and third direction switching claws 318a, 318b, 318
c becomes a solid line. Then, the first paper ejection detection sensor 321 is turned on by conveyance of the original 69, and after a time B, the second paper ejection detection sensor 322 is turned on.
When the first paper discharge detection sensor 321 turns OFF and the second paper discharge detection sensor 322 turns OFF and falls, it means that the trailing edge of the document 69 has passed the second paper discharge detection sensor 322 position. Therefore, at this timing, turn roller 31

F. Then, the first to third direction switching claws 318a. 318b and 318c are in the state shown by the dashed-dotted line, and in this state, when the delay time C, which takes into account the delay time of the operation of the reversing solenoid 316, has elapsed, the turn roller 315 rotates in the reverse direction (R). With the reverse rotation of the turn roller 315, the original 69 passes above the second direction switching claw 318b and is discharged in an inverted state to the original stack tray 382 side of the original reversing unit 52. This results in the flow of the original 69 as shown by the arrow in FIG. 129 (bl).
is a timing difference due to a difference in the placement positions of the first and second paper discharge detection sensors 321 and 322 on the conveyance path. FIG. 127(C) shows the timing when the original 69 is reversed and conveyed onto the contact glass 17. In this case, the turn roller 315 and the conveyance heald 53 start forward rotation (F) at the same timing, and at the same time, the reversing solenoid 316 is turned on. As a result, the first, second and third direction switching claws 318
a, 318b, and 318c are solid lines. and,
The first paper ejection detection sensor 321 is turned ON by conveyance of the original 69, and the second paper ejection detection sensor 322 is turned on after time B.
When turned ON, the reversing solenoid 316 is turned OFF when the second discharge detection sensor 322 rises. When the reversing solenoid 316 is turned OFF, the third direction switching pawl 318c is brought into a state shown by a chain line. Furthermore, the conveyor belt 53 starts rotating in reverse at approximately the same timing as the fall of the first discharge detection sensor 321, and when the leading edge of the document 69 reaches the conveyor belt 53, the document 69 is moved by the conveyor belt 53 to the contact glass 17. It is pulled in to the side and conveyed onto the contact glass 17. When the document 69 is completely conveyed onto the contact glass 17, the turn roller 315 and the conveyance belt 53 stop. As a result, the document 69 flows as shown by the arrow in FIG. 129 (C1). Note that the time period indicates the timing until the document 69 reversed by the turn roller 315 reaches the conveyor belt 53. (dl indicates the timing when the document 69 is discharged onto the document output tray 285 of the document transport unit 10. In this case, the turn roller 315 and the transport belt 53 start forward rotation (F) at the same timing. ,
At the same time, the reversing solenoid 316 is turned on. This results in
First, second and third direction switching claws 318a, 318b
, 318c are shown as solid lines. Then, the first paper ejection detection sensor 321 is turned on as the original 69 is transported.
After a delay of time B, the second paper ejection detection sensor 322 is turned on, and when the document 69 passes through the second paper ejection detection sensor 322 and a time E elapses after this sensor 322 falls and passes through the paper ejection roller 319. Turn roller 315 and conveyance belt 53 stop, and document 69 is discharged onto document discharge tray 285 of document conveyance unit 51. This allows the first
The flow of the document 69 is as shown by the arrow in FIG. 29 fd+. [10.

If it is determined in step 5130-13 that the copy job has been completed based on the value of the discharged sheet counter, stabilization and document conveyance are repeated in accordance with each mode until the job is completed (S130-14 and 3130-15). Step 5
When the processing in step 130-15 is completed, check the status of the stable abnormality flag and sort mode flag in step 5130.
