Description

[Detailed description of the invention] Industrial applications The present invention relates to a copying machine with a stapling device.

2. Description of the Related Art An example of a conventional copying machine equipped with a stapling device will be described with reference to FIG. The copying machine main body (hereinafter referred to as collation device) 1 includes an automatic document feeder (ADF) 2 and
A sorter 3 is provided. The operation of this device will be explained below. Now, set the original 5 facing down in page order on the set table 4 of the ADF 2, set the required number of copies, and press the print button (not shown).
The first page of original 5 is sent to a predetermined position on contact glass 6, an image is formed on photoreceptor 8 by reading by optical system 7, and the image is transferred to copy paper 10 fed from paper feeder 9. The paper is then reversed in the conveyance path 11 and sequentially discharged from above into each bin 12 of the sorter 3 with the image surface facing downward. Next, the same process is repeated for the second original 5 and subsequent originals 5. When all the copies are completed, the copy sheets 10 are stored in bins 12 as many as the initially set number of copies, arranged in page order. In other words, collation is thus completed.

FIG. 7 shows a method of branching to each bin 12. When the bin SQL 1 3 is turned on, the lever 15 rotates clockwise via the spring 14.
The claw 16, which is coaxial with , moves from the dotted line position to the solid line position. As a result, when the copy paper 10 is transported by the transport roller 17 and the driven roller 18, it is deflected by the claw 16, and the copy paper 10 is deflected by the transport roller 17 and the paper ejection roller 19 into the bin 10.
The paper is ejected. This branching device is provided in all the bins 12, and can branch the copy paper 10 to each bin 12.

The sorter 3 is also provided with a stapling device 20 as shown in FIG. This stapling device 20 has a stand 2 that moves up and down so that it can stop at the position of each bin 12.
1, and this table 21 is moved up and down by a drive screw 22. This stapling device 20 is composed of a stapler 23 as shown in FIG. 9, and a chuck device 24 as shown in FIG. has been done. Now, in FIG. 8, the copy sheets 10 discharged by the paper discharge roller 19 are deposited on the bin 12. As shown in FIG. This bin l2 has a stopper 25 and a press plate 26 that presses the copy paper 10 against the stopper 25 to perform paper alignment work. This stopper 25 is held by a spring (not shown), but when the stand 21 comes to the position of the bottle 12, the stopper 25 is held horizontally by the lever 26 provided on the stand 21, like the bottle 12 at the position A. Fall down like that.

Here, the operation of the stapler 23 will be explained based on FIG. 9. The copy paper 1o is carried to a position on a pedestal 27 by a chuck device 24, which will be described later.

This stapler 23 is formed so that a cartridge 29 containing a large number of staples 28 can be attached and detached therefrom.

This needle 28 is fed by a feed belt 31 driven by a stabler drive motor 30. And arm 3
2 is swung up and down by the stapler drive motor 30, and the head 33 moves up and down as well, striking the staple 28 against the pedestal 27.
It will spell 0. In other words, the stapler 23 plays the role of a stapler.

The operation of the chuck device 24 is also shown in FIGS. 10 to 12.
This will be explained based on the diagram. The stapling device 20 is attached to the bin 12
When the chuck motor 34 is stopped at the position indicated by the black arrow, the chuck motor 34 rotates in the direction indicated by the black arrow, thereby causing the arm 36 as an arm member to move in the direction indicated by the black arrow via the belt 35. and,
When the sensor 37 detects the chuck member 36, the chuck motor 34 is stopped, the SOL 37 is turned on, and the signal is transmitted to the gears 40, 41, 42 via the spring 39, and the arm 36 operates to grip the copy paper 1o. After these pair of arms 36 grab the copy paper 1o, the motor 34 starts to rotate in reverse, the arm 36 moves in the direction of the white arrow, and when the home sensor 43 detects the detection, the motor 34 stops, and the stapler 23 performs needle driving.

As shown in FIG. 13(a), when the arm 36 grabs the copy paper 1o, the bin 44 fixed to the arm 36 enters a part of the paper return lever 45, and the motor 34 (see FIG. 12) When the is reversed, the return lever 45 similar to the arm 36
also moves to the left. After punching the needle, Figure 13 (
As shown in b), when the SOL 38 (see FIG. 11) is turned off and the arm 36 is opened, the bin 44 is disengaged from the return lever 45, and the return lever 45 is pushed out by the spring 46. Accordingly, the stapled copy paper 10 is also pushed out by the return lever 45 and returned to its original position as shown in FIG. Thereafter, the stapling device 20 is lowered to the next bin 12, and the same operation is repeated to make a copy.

Problems to be Solved by the Invention In general, the copying speed of the above-mentioned copying machine is about 60 pages per minute (A4 size), and for this class of copying machine, the number of original pages is 30 or less. is mostly used. For this reason, the stapler 23 used in this copying machine is capable of binding up to 30 sheets of copy paper 1o at a time.

In this case, in order to staple more than 30 sheets of copy paper 10, the main body of the stapler 23, the staple 28, the stapler drive motor 30, etc. may be made larger, but this increases cost.

However, although it is very rare, there may be a case where it is desired to perform staple binding using more than 30 sheets of copy paper 1o. In such a case, in the conventional apparatus, the stapler 23 and its attached parts must be made larger as described above, and as a result, a problem arises in that costs increase as the parts become larger.

Means for Solving the Problems Therefore, in order to solve such problems, the present invention has a collating device and a sorter attached to the collating device, in which the copy sheets sent onto each bin are arranged in pairs, upper and lower. In a copying machine comprising a stapling device equipped with a chuck device which is gripped by an arm member and carried to a stapler position, the copying machine is set to a mode in which no stapling is performed when the number of copies discharged into the bin exceeds the number of copies that can be stapled by the stapler. a stapling mode selection that can select a mode in which when the number of copies discharged into the bin exceeds the number of sheets that can be stapled by the stapling device, the copy paper is discharged into another bin and the copy papers in each bin are stapled; The means were set up.

Therefore, when the number of sheets that can be stapled is exceeded, the stapling mode selection means selects a mode in which only collation is performed without stapling, or when the number of sheets that can be stapled is exceeded, the remaining sheets are discharged to another bin. By selecting the stapling mode for each, it is possible to use different stapling modes depending on the purpose of copying.

Embodiment An embodiment of the present invention will be described with reference to FIGS. 1 to 5. The overall configuration of a copying machine with a stapling device and its series of operations are based on the conventional technology (Figs. 6 to 12).
(see figure), the explanation here will be omitted, and the same reference numerals will be used for the same parts as in the conventional example.

In this embodiment, a collating device 1 as shown in FIG. 6 and a pair of upper and lower arms 36 grip copy sheets 10 discharged onto each bin 12 of a sorter 3 attached to the collating device 1. In a copying machine comprising a stapling device 20 equipped with a chuck device 24 that transports the copy sheets to the position of the stapler 23, a mode is provided in which the stapling is not performed when the number of sheets of copy paper 10 discharged into the bin 12 exceeds the number of sheets that can be stapled by the stapling device 20; When the number of copy sheets 10 discharged to a bin 12 exceeds the number of sheets that can be stapled by the stapling device 20, a mode can be selected in which the copy sheets 1o are discharged to another bin 12 and the copy sheets 10 in each bin 12 are stapled. This is provided with means for selecting a stapling mode.

FIG. 1 shows the operating section 47 of the main body of the copying machine, which is provided with the selection function of the stapling mode selection means. In this case, the operation section 47 includes a print start key 48, a number key 49, a set number display section 50, a copy number display section 51, and when a stamp is stamped, the set number of copies are sorted and output. sort selection key 52;
Furthermore, various keys such as staple A53 and staple B54, which are keys for selecting a staple mode, are provided.

In such a configuration, the stapling mode selection means which constitutes the main part of this embodiment will be explained based on the flowcharts of FIGS. 2 and 3. First, the flow shown in FIG. 2 shows the contents that operate when the staple A53 key of the operation section 47 is selected. Now that staple A
When key 53 is selected, the number of copies is set, and copying is started, the sheets are sorted according to the set number of copies and are ejected. At this time, the ADF 2 counts the number of copy sheets 10 while feeding them. When all the copies are ejected, the number of copies in one bin 12 is 30.
If the number of sheets is less than 31, stapling is performed, whereas if the number is 31 or more, the process ends without stapling. This series of operations corresponds to the mode J in which stapling is not performed when the number of copy sheets 10 discharged into the bin 12 exceeds the number of sheets that can be stapled by the stapling device 20.

In addition, the flow in FIG.
This shows the contents that operate when key 4 is selected. Now, if you select the key for staple B54, if the set number of copies is less than (1/2) x the number of bins (here, it is 10 because it is a 20-bin sorter), then the number of copies per bin is When the number of copies exceeds 30, the 31st copy and subsequent copies are discharged to other bins 12. After the copying is completed, all the bins 12 are stapled and the process ends. For example, if you want to copy 50 original pages, first staple the 1st to 30th pages,
Next, the 31st to 50th sheets are stapled, that is, one copy is divided into two and stapled. Such a series of operations is performed as follows: When the number of copies 10 discharged to the bin 12 exceeds the number of sheets that can be stapled by the stapler 20, the copies 10 are discharged to another bin 12, and the copies 10 in each bin 12 are stacked. This mode corresponds to the mode of "staple". Next, the configuration of the control block of this device will be briefly explained based on FIGS. 4 and 5. The CPU 55 is a well-known microcomputer, which includes a ROM 56, a RAM 57, and even
It is connected to a plurality of ■/○ elements 58 and 59. Further, the CPU 55 is connected to the ADF control unit 60 and communicates with it using a serial communication method, and executes sequence control, arithmetic processing, etc. related to copying. In this case, the ADF control unit 6
0 is connected to the signal group 60a and the load group 60b, respectively. Furthermore, signal lines of the well-known key matrix 62 and LED matrix 63, which are a key switch on an operation panel (not shown) and an LED display, are connected to the /061 to perform input/output processing.

Furthermore, the signal group 65 connected to I/064 is connected to various components as shown in FIG. 5(a), and the load group 67 connected to ■/066 is connected to the signal group 65 shown in FIG. Various members shown in the figure are connected, and input/output processing is performed using these members. On the other hand, the signal group 68 and load group 69 connected to /058 and /059, respectively, belong to the main body of the copying machine, and detailed explanation thereof will be omitted here.

Effects of the Invention The present invention provides a stapling device that includes a collating device and a chuck device that uses a pair of upper and lower arm members to grasp copy sheets fed onto each bin of a sorter attached to the collating device and transport them to a stapler position. In the copying machine, there is a mode in which the copy paper discharged into the bin exceeds the number of sheets that can be stapled by the stapling device, and a mode in which the copy paper discharged into the bin cannot be stapled by the stapling device. Since the stapling mode selection means is provided, the stapling mode selection means can select a mode for ejecting the copy paper to another bin and stapling the copy paper in each bin when the number of copies exceeds the number of sheets.
When the number of sheets that can be stapled is exceeded, select a mode that only collates without stapling, or when the number of sheets that can be stapled is exceeded, select a mode that discharges the remaining sheets to another bin and staples each one. This makes it possible to use different stapling modes depending on the purpose of copying, thereby further expanding the range of applications of the copying machine.
