Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a copying mode selection device for selecting various copying modes in a copying machine.

[Conventional technology and its problems]

In recent years, copying machines have dramatically improved their copying performance, and have also expanded and reduced copying, created binding margins (stitched copy mode), biased copying (anamo copy mode), double-sided copying (double-sided copy mode), and composite copying (combined copy mode). It is now possible to select from a large number of copying modes, such as image editing copying (copy mode), image editing copying (editor copy mode), and multi-functionality is progressing.

Along with this, the number of operation keys, indicator lights, etc. placed on the operation panel of the copying machine has increased, making the operation for selecting the copying mode complicated and placing a heavy burden on the operator. (It depends on the amount of spray.)

Therefore, the arrangement of operation keys, indicator lights, etc. in a copy mode selection device is an important issue that affects the operability.

On the other hand, 2-in-1 is one of the effective modes for copying machines equipped with a document feeder that transports the document to the exposure position on the document table and an automatic document feeder that automatically feeds the document. There is a mode.

The 2-in-1 mode is a mode in which two originals are sequentially conveyed one by one on the original table, and they are arranged adjacent to each other, and the images of the two originals are copied onto one copy paper. This is selected when, for example, images of two original documents are to be combined and copied onto a single sheet of copy paper that is twice the size of the original.

By adding the 2-in-1 mode to the modes that can be executed by the copying machine, when performing the above-mentioned copying work, the operator can save the trouble of placing the original on the document table.
Work efficiency is greatly improved.

SUMMARY OF THE INVENTION An object of the present invention is to provide a copying mode selection device that is easy for an operator to use and can easily select a 2-in-1 mode from among a wide variety of copying modes provided in a copying machine.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention sequentially transports two originals one by one onto a document table, arranges them adjacently, and displays images of the two originals. The 2-in-1 selection means for selecting the 2-in-1 mode for copying onto a single sheet of copy paper and the 2-in-1 display section corresponding to the 2-in-1 mode can be selected as the original selection means for selecting the type of original to be copied. The present invention is characterized in that a plurality of original display sections corresponding to respective originals are provided in an adjacent original selection area.

[For production]

In the 2-in-1 mode, two originals are sequentially conveyed one by one onto the original table and placed side by side.

A 2-in-1 selection means for selecting such a 2-in-1 mode is provided in the document selection section, and when the operator selects a copying mode, the 2-in-1 mode is selected based on the characteristics of the form of the document. will be selected as one of the selected modes.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 4 is a front sectional view showing the general structure of a copying machine A incorporating a copying mode selection device.

In addition to the standard equipment required for the basic electrophotographic copying process described later, the copying machine A has an intermediate tray unit B that is necessary for executing double-sided copy mode or composite copy mode, and an automatic document copying system. Automatic document feeders rIt, (ADF) necessary for the ADF mode, which conveys original documents, are installed in the center and top of the main body of the copying machine A, respectively.

First, the basic copying process and standard equipment will be briefly explained.

A photoreceptor drum l is supported at approximately the center of the upper part of the main body of the copying machine A so as to be rotatable in a counterclockwise direction, and around it,
An eraser lamp 2, a charger 3, an inter-image eraser 2a consisting of an LED array, a developing device 6, a transfer charger 7, a separation charger 8, and a blade type cleaning device 9 are provided. The photosensitive drum 1 is provided with a photosensitive layer on its surface, and is uniformly charged by passing through a charging charger 3, and then subjected to image exposure from an optical system 10.

The optical system 10 is installed below the original glass 16 so that the original image can be scanned, and includes an exposure lamp 11 and a movable mirror 1.
2a-c, a projection lens 12e, and a mirror 12d. Exposure lamp 11 and movable mirror 12a

It is driven by a scan motor (not shown) to move at a speed of /2n.

The copy paper storage section consists of an upper elevator-type storage section 42 and a lower cassette-type storage section 43, both of which can be pulled out from the copying machine main body to the front side by means of rails 46.47 and 48.49. It is said that

Each storage section 42,43 is provided with a size sensor 121122 for detecting the size of copy paper. The size sensors 121 and 122 include, for example, a plurality of reed switches provided in the main body of the copying machine, and a plurality of permanent magnets provided in each storage section 42 and 43 to selectively operate these reed switches according to the size. It consists of

The copy paper in the storage section 42 is fed by the rotation of the paper feed roller 18.
The copy paper in the storage section 43 is fed by the rotation of the paper feed roller 19.
Selectively, one of them is the handling rollers 20 to 23.
The sheets are separated and fed one by one by the transport rollers 29 to 31.
．． It is conveyed to the timing roller pair 13 at 24-26, 32, 34 and 27.28.

After the copy paper is temporarily stopped by the timing roller pair 13,
The toner image formed on the photoreceptor drum 1 is sent to the transfer position in synchronization with the toner image formed on the photoreceptor drum 1, and the toner image is transferred by the transfer charger 7, separated from the surface of the photoreceptor drum l by the separation charger 8, and transferred to the conveyor belt. 4 to the fixing device 5 where it is fixed.

The fixing device 5 consists of a heating roller 5a with a built-in heater, and a pressure roller 5b that rotates in pressure contact with the heating roller 5a. When the copy paper passes between these rollers 5a and b, the toner is removed. Fixation is performed by crushing and thermally welding to copy paper.

The copy paper after fixing is transported by a transport roller 14 and a pair of discharge rollers 1.
The photosensitive drum 1 is discharged onto the discharge tray 36 by the photosensitive drum 5, and the residual toner is removed by the cleaning device 9, and the residual charge is removed by light irradiation from the eraser lamp 2, so that the photosensitive drum 1 is ready for the next copying.

By using the intermediate tray unit B installed as additional equipment in addition to the above standard equipment, it is possible to perform duplex copy mode and composite copy mode.

The intermediate tray unit B has rails 44.4 at both ends.
5, and is supported by the copying machine main body, and can be pulled out from the copying machine main body in a direction perpendicular to the copy paper conveyance path.

In the duplex or composite copy mode, the lever 41 for switching the copy paper transport path provided between the transport roller pair 14 and the ejection roller pair 15 is set to the state shown by the solid line in the figure, and the copy paper is Once the paper is sent from the pair of transport rollers 35 through the guide plate 37 into the intermediate tray unit B, it is fed again.

That is, the copy paper that has been copied on one side is guided by the guide plate 37 and conveyed to the conveyance rollers 50 and 51. The switching lever 59 is rotatable about the shaft 85 as a fulcrum, and is set on the lower conveying roller 50 side (indicated by the solid line in FIG. 4) in the double-sided copy mode. The copy paper is guided by the upper surface of the lever 59 and fed in, and then passed through the conveyor rollers 52 to
55, it is conveyed to the left side of the figure, and then reverse conveyed by rollers 56 and 57.
The paper is reversed by the reversing guide 93 and fed onto the intermediate tray 58 with the copied side facing up.

Then, the paper is aligned on the intermediate tray 58 by the alignment mechanism, and 1
Paper is re-fed one by one.

In addition, in the composite copy mode, the switching lever 59 is set on the upper transport roller 51 side (the state shown by the chain line in FIG. Guided directly to intermediate tray 5
8 with the copied side facing down. Then, the sheets are aligned on the intermediate tray 58 by the alignment mechanism, and the sheets are re-fed one by one by the counterclockwise rotation of the re-feed roller 38, as in the case of double-sided copying.

The re-fed copy paper is sorted by sorting rollers 39 and 40 and conveyed through conveying rollers 32 to 34 to the timing roller pair 13, whereafter double-sided copying or composite copying is performed in the same way as in the normal copying process. .

On the other hand, on the top surface of the main body of copying machine A, there are a document transport device DF that transports the original to the exposure position, an automatic document feed mechanism AD that automatically feeds the document to this document transport device DF, and a document transport device DF. An automatic document feeder (ADF) is installed in which a document reversing mechanism R for reversing the front and back of the document discharged from the document sheet is connected.

When it is detected that this ADF is electrically connected to the main body of the copying machine 8 and installed at a predetermined position, the controls of the ADF and copying machine A are associated with each other, and the operation mode of copying machine A is changed to ADF mode. Can be switched.

The ADF mode is a mode in which when a print key 71 provided on the copying machine A, which will be described later, is turned on, the copying machine A operates the ADF while remaining in a standby state, and the paper feeding motor 302 for the rollers and the conveyance Conveyance motor 3 for belt 304
01 is started, the document placed on the document tray 303 is fed along the top surface of the document glass 16 which serves as a document table, and the paper feed sensor 3 detects the feeding of the document at its leading edge.
After a predetermined time has elapsed after passing through 10, it is stopped at a predetermined position, and a start signal is output from the ADF to copy machine A to start the copying operation.When the final scan of the original is completed, the copying machine is started! ! An operation signal is output from 11A to the ADF, and the ADF discharges the original onto the paper discharge tray 306. At this time, the document sensor 311 detects whether the next document is on the document tray 303 or not.

The basic ADF mode is as described above, but when a double-sided original is set on the original tray 303 and a double-sided original copy mode, which will be described later, is selected, the original reversing mechanism R is also activated at the same time. That is, the document is placed on the document glass 16 by the transport belt 3.
When the document is conveyed to the document reversing mechanism R at step 04, the switching lever 307 that switches between ejecting the document and sending it to the document reversing mechanism R operates, and the document is sent to the document reversing device FIR, which is driven by the reversing motor 320. The front and back sides of the document are reversed by the belt 321, and the document is sent to the document transport device DF again. The document detection sensor 312 detects that the document is sent to the document reversing mechanism R. Further, the document discharge sensor 313 detects that the document is discharged to the paper discharge tray 306.

FIG. 5 is a block diagram showing a control circuit for the copy mA.

Input buffers 207 to 210 controlled by the first CPU 201 via a decoder 214 are connected to operation keys provided on an operation panel 70 and sensors and switches provided in each part, which will be described later. The output buffers 1211 to 213 to be controlled are connected to a main motor (not shown), a developing motor, various clutches, a transfer charger 7, an electrostatic charger 3, and a display matrix circuit 218 for lighting various indicator lights on the operation panel 70. . Note that 216 is a decoder, and 230 is a battery-backed RAM.

The first CPU 201 communicates with the second CPU 202 and third CPU 203 through a communication line 219.

The second CPU 202 controls the operation of the optical system 10, and includes a scan motor control circuit 205 and a projection lens 12e.
a variable power lens control circuit 206 that moves the lens, a fixed position switch 500, and a timing switch 501 that generates a timing signal to rotate the timing roller 13.
etc. are connected.

FIG. 2 is a front view of the operation panel 70 of the copy 4iA.

On the operation panel 70, in order to improve operability, various operation keys and indicator lights are classified according to their functions, and the groups are arranged according to each classified group.

In the figure, the first operation area API includes operation keys for selecting the first group of modes, which can be realized by devising the control of the standard equipment described above, among the various modes that can be executed in the copying machine A. In the second operation area AR2, operation keys and indicator lights for selecting the second group mode executed using additional equipment are arranged. There is. In addition, the third operation area A

In addition, in the operation area ED adjacent to the first operation area ARI, setting keys and indicator lights related to the editor copy mode that can be executed when an additional equipment such as an editor sheet (not shown) and a pen-type input device are attached are arranged. By covering the operation area ED and the first operation area API with a sliding door Z when not in use, the operation panel 70 can be visually simplified. ing.

Further, at the right end of the figure, a data reading key IC is installed when selecting a mode and setting conditions using an IC card that stores data such as modes and copying conditions.

FIG. 3 is a partially enlarged view showing the arrangement relationship in the first operation area ARI in the operation panel 70. FIG.

As shown in the figure, in the first operation area API, a matrix arrangement method is adopted in order to enable more selections with a smaller number of operation keys and to simplify hardware such as wiring. That is, pictographs corresponding to each mode of the first group or characters indicating functions that can be specified in each mode are arranged in a grid pattern, and at the bottom of each column there is a column designation key 7.
21 to 726 are provided in principle for each column,
Row designation keys 731 to 734 are provided at the right end of each row, respectively. Further, above the row designation key 731, a selection input indicator light 889 using an LED, a miniature bulb, or the like is provided to indicate that an input from the row designation keys 731 to 734 is being waited for.

By pressing any one of these column designation keys 721 to 726 and any one of row designation keys 731 to 734, one mode in the first group is selected or one mode is selected. Functions can be specified.

The column specification key 721 is used to specify the leftmost column of the diagram in which pictograms corresponding to the Anamo bias copy mode, non-copy mode, and fake copy mode are drawn, one for each day of the base, in order from the top. , the column designation key 722 is operated to select one of the refinement 1 copy mode, ribbing 2 copy mode, frame empty mode, punch hole erase mode, and the margin value of each mode. The binding 2-copy mode is suitable for copying on both sides of copy paper, but when duplex copying is performed using only standard equipment, the operator manually turns the copy paper upside down.

Column designation keys 723 and 724 are operation keys for selecting enlarged copy mode or reduced copy mode, respectively, and when these modes are selected, row designation key 7
By pressing any one of 31 to 734, one of four preset magnifications can be selected.

Note that the column designation keys 725 and 726 are both operation keys related to the zoom function that arbitrarily selects the magnification in the enlarged copy mode or reduced copy mode, and are used to select the magnification setting means and to store and read the magnification. Operated when making selections.

At the upper left of the pictographs or displayed characters arranged in the first operation area ARI, the lights of the LEDs 851 to 870, which are bank lights, can be directly seen, as indicated by circles. These LEDs 851 to 870 blink while the corresponding mode or function is being operated, and when the operation is completed, the one corresponding to the selected mode or function turns on and the others turn off (Fig. (The black circle represents the off state.)

Now, the procedure for selecting the book copy mode, which is one of the standard modes, by operation in the first operation area ARI will be explained.

First, in the initial state of the copying machine A, the print key 71 is lit in green. Now, if you press the column designation key 721,
The three LEDs 851 to 853 in the leftmost column flash in green, and the selection input indicator 889 flashes to prompt the press of the row designation keys 731 to 734, and the print key 71
lights up in red.

When the row designation key 733 is pressed to select the book copy mode, among the blinking LEDs 851 to 853, only the LED 853 corresponding to the book copy mode lights up in green, and the others turn off.

This completes the operation for selecting the book copy mode, and the print key 71 lights up in green again. Thereafter, when the print key 71 is turned on, copying in the book copy mode is started, and under the control of the second CPU 202 described above, two scans are performed with different lighting times of the exposure lamp 11 and different scan lengths.

FIG. 1 is a partially enlarged view showing the arrangement relationship in the second drying area AR2 in the operation panel 70.

The second operation area AR2 is an operation area for selecting a mode related to additional equipment installed especially for the convenience of copying work with a large number of sheets, and for selecting various functions provided in the additional equipment.

In the second operation area AR2, additional equipment is installed to automate a series of copying operations from placing the original to tidying up the copy paper after copying, and to improve work efficiency especially when copying a large number of sheets, namely an ADF, A mode that can be executed when the intermediate tray unit B, a sorter (not shown), and a paper processing mechanism (not shown) are installed is selected.

In this second operation area AR2, the arrangement of pictograms representing options is devised so as to follow the flow of thought of an operator who is making preparations for a copying operation. In other words, ■ What is the format of the manuscript? ■ How should the copy image be laid out on the copy paper? ■ How should the copy paper be sorted after copying? ■ How should the copy paper be final processed? There are four selection sections, namely, the original selection section 901, the layout selection section 902, and the selection operation in the order of ■→■→■→■, such as binding several sheets at a time or folding in half. For sorting, the selection section 903 and paper processing selection section 904 are arranged in order from the left! has been done.

However, the selection area that can be operated is limited depending on the installation status of additional equipment. For example, when selecting the sorting method (■), when a sorter (not shown) is installed as additional equipment, it becomes possible to select one of non-sorting mode, sorting mode, and grouping mode. As for selection, when the paper processing mechanism is installed, it is possible to select any one of a non-processing mode, a stamp mode in which several sheets are bound with a Stella pull metal fitting, a stamp mode in which a stamp is stamped, and a Stella pull stamp mode.

Therefore, in the copying machine ff1A of this embodiment, since a sorter and a paper processing mechanism are not installed as additional equipment, the sorting selection section 903 and the paper processing selection section 904 are not subject to operation.

In the document selection area 901, options for the ADF mode are collected and arranged. However, as described above, this document selection section 901 is regarded as a selection area for the format of the document, so although the book copy mode can be executed as standard equipment, the book copy mode can also be selected within this section. It has become.

That is, in the manuscript selection area 901, pictograms each indicating a single-sided manuscript, a double-sided manuscript, a book manuscript, and a 2-in-1 manuscript, which are provided as options, are arranged, and in the upper left of each pictogram,
LE09, which is a bank light, is indicated by a circle.
The lights from 21 to 924 can be seen directly. LED9 that constitutes each document display area along with each pictogram
21 to 924 are turned on when the corresponding options are selected by pressing a rotating original selection key 911 provided below the original selection section 901.

A 2-in-1 original refers to a set of two originals placed next to each other, and when copying in 2-in-1 mode, two sheets of original are printed on two sheets of paper, contrary to book copy mode. images can be copied onto one sheet of paper.

When a single-sided original, double-sided original, or 2-in-1 original is selected as the original by operating the original selection section 901, the above-mentioned AD
F automatically feeds and transports the document, and flips the document upside down. However, for book documents, it is assumed that the ADF is not used.As will be described later, when the document sensor 311 detects the document in the document tray 303, the book document is automatically fed, transported, and reversed. Copying in copy mode is not executed.

In the layout selection area 902, the layout selection key 9
Pictograms and LEDs 925 to 927 corresponding to the single-sided copy mode, double-sided copy mode, and composite copy mode, which can be selected by the operation 12, are arranged, and the way to use the intermediate tray unit B is selected.

Next, based on the flowcharts in FIGS. 6 to 23,
The operation of the control circuit of copying machine A will be explained.

In the flowchart below, on-edge refers to a state change when a switch, sensor, or various signals changes from an off state to an on state.
Off-edge refers to a state change when changing from an on state to an off state.

FIG. 6 is a main flowchart schematically showing the operation of the first cPU 201.

When the program starts, first, in step #1, the RAM 230 is cleared, various registers are set, and initial settings are executed to bring the copier A into the initial state.
In step #2, an internal timer that determines the processing time of one routine of the first CPU 201 is set.

Next, document selection key processing (step #3) for controlling the display in the second operation area AR2 of the operation panel 70 described above is performed.
), layout selection key processing (step #4) is executed, and then, in step #5, the second group mode setting processing is performed.

After executing the first group mode setting process in step #6, a copying operation is performed in step #7.

In step #8, other processing necessary for operation of the copying machine is performed, and in step #9, communication with other CPUs is performed.

After performing these processes, an internal timer is waited in step #10, and the process returns to step #2. As a result, the length of one routine is kept constant, and the processes from step #2 to step #10 are repeated while the power is turned on.

FIG. 7 is a flowchart of the document selection key processing routine of step #3 described above.

When the original selection key 911 is pressed (step #701L
First, in step #702, a timer TP is set.

When the ADF is installed (step #703)
, the lighting states of the LEDs 921 to 924 are sequentially changed. In other words, when the original selection key 911 is pressed, the LED
If the LED 921 is on (step #704), the LED 921 is turned off and the LED 922 is turned on in step #705. If the LED 922 is lit (step #7
06), the LED 923 is turned on instead of the LED 922. Similarly, if the LED 923 is lit (step 97
08), turn on the LED 924 in step #709, and
If the ED924 is lit, the LED is turned on in step #710.
Turn on 921.

On the other hand, if the answer in step #703 is NO, that is, if the ADF is not installed, it is not possible to reverse the document and transport the document using the document reversing mechanism R, so double-sided documents and 2-in-1 documents cannot be used as documents. cannot be selected. Therefore, in this case, the lighting of LEDs 921 and 923 corresponding to the one-sided original and the book original are switched on (steps #711, 712, and 71).

FIG. 8 is a flowchart of the layout selection key processing routine of step #4 described above.

When the layout selection key 912 is pressed (step #7
21L First, in step #722, remove the intermediate tray unit B.
A check is made to see if it is attached, and if no, the process returns to the main routine.

When the intermediate tray unit B is installed, in step #723, after the timer TQ is set, the L
Controls the lighting of ED925 to 927, that is, LED9
25 is lit (step #724), the LED
Turn on LED 926 instead of 925 (Step #7
25). Similarly, if the LED 926 is lit (step #726), the LED 927 is lit in step #727, and if the LED 927 is lit, the LED 925 is lit in step #728.

FIG. 9 is a flowchart of the second group mode setting routine of step #5 described above.

First, in step #751 and step #752, the timer TP and timer TQ are waited for, respectively, and after waiting for the completion of document selection or layout selection by the operator's key operation, the following step gaff 53 is performed.
~Execute step #796.

In steps #753 to #796, a combination of four options selected by the original selection key 911 and three options selected by the layout selection key 912 is selected.
Two types of mode settings are performed.

That is, when a single-sided original is selected as the original (step #753L), when a double-sided original is selected (step #779), and when it is a book original (step 9785).
), 2-in-1 original (step #791), check the selection results using the layout selection key 912 (step #754 and step #T56, step #780 and step #782, step #7)
86 and step #788, step #792 and step #794), and step #755 to #778,
Steps #781-784, Steps #787-790
, Steps #793 to #796 set one of the 12 modes. For example, when a book manuscript is selected (Step 4785L Step #
If it is determined that double-sided copying, which forms images on both sides of copy paper in 78 days, is selected, the book/double-sided copy mode is set in step #789, and step #788
If the answer is NO, it means that composite copying has been selected, and therefore, in step #790, the setting of the active/composite copy mode is performed.

FIG. 10 is a flowchart 1 showing a part of the first group mode setting routine of step #6 above, and in the same figure, there are three types of pictograms corresponding to the leftmost row of the first operation area ARI. The mode setting process is shown.

At step #801, column designation key 7210 on edge is checked, and if yes, at step #802, L
The EDs 851 to 853 and the selection manual indicator light 889 are blinked, and when the answer is NO, the process moves to step #803.

At step #803, the LEDs 851 to 853 and the selection manual indicator light 889 blink li1! After the line designation key 731 is pressed to select the analog copy mode (step #811), in step #812, the LED 8
51 is turned on, and the LEDs 852 and 853 and the selection input indicator light 889 are turned off, and in step #813, settings for the copying operation in the analog copy mode are executed.

If the line specification key 732 is pressed (step #81
4), turn on only the LED 852 (step #815
), the non-copy mode is set in step #816. Further, when the line designation key 733 is pressed (step #817), only the LED 853 is turned on (step #81B), and the non-copy mode is set in step #819.

FIG. 11 is a flowchart of the copy operation routine of step #7 described above.

In step #101, first, it is checked whether the print key 71 is turned on. If YES in step #101, then in step #102 it is determined whether or not the mode is to use the ADF.If the mode is to use the ADF and there is a document in the document tray 303, In step #103), the ADF start signal is turned on in step #104, and the process proceeds to step #121.

If the mode does not use ADF, step #10
5, the copy start flag is set to "l", and when the mode is to use the intermediate tray unit (step 91).
06) If the back side copy flag is "0" (step #107L step #108, set the front side copy flag to "0").
