Abstract

PURPOSE:To prevent the erroneous instruction for the staple processing operation by an operator by operating an alarm means when it is judged that the designated copying quantity supplied from an input means exceeds a staple binding limit quantity. CONSTITUTION:When a set quantity is inputted from the ten key 202 of the input device of a copying machine, a CPU 300 stores said set quantity into a RAM 302, and an original is set into an ADF 3, and a start key 201 is pressed, the copies in the set quantity are prepared. In this case, if a staple key 220 is pressed, the copies are binding-processed by the stapler of a sorter, and if the set quantity exceeds a previously set staple binding limit quantity, a staple- disable display device 234 is operated to prohibit the operation of the stapler. Therefore, the erroneous instruction for the staple processing operation by an operator can be avoided, and the generation of staple mistake can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a post-processing control device that uses a stapler to staple sheets ejected from a copying machine and stacked for each copy of the same original.

Prior Art When sorting multiple copies of sheets from a multi-page original so that copies of the same original are collected in the same bin, an automatic document feeder feeds the original in page order to the original reading section of a copying machine. and make the required number of copies for each page.
This is done by discharging copies of the same document into each bin of a sorter. This sorting method is called stack mode.

Devices that automatically staple copies loaded and output from a copying machine are known, but with conventional devices, there is a problem with the number of copies to be stapled.
Since the stapler operates without hitting the stapler, if the number of copies exceeds the number of copies that the stapler can process, problems may occur such as the stapler not being able to be stapled reliably or the stapler not entering the stapler and falling into the machine. Ta.

Problems to be Solved by the Invention In view of the above-mentioned circumstances, the present invention provides a sheet post-processing device that automatically staples sheets ejected from a copying machine and stacked for each copy of the same original.
An object of the present invention is to provide a sheet post-processing control device that can eliminate problems caused by stapling when the number of sheets discharged into each bin of a sorter exceeds the stapling limit of a stapler. do.

Means for Solving the Problems In order to solve the above problems, the present invention provides a means for copying an original onto a sheet, a means for inputting a designated number of copies for one original, and a means for copying a sheet on which the original is copied into the same original. In a sheet post-processing control device having a means for discharging sheets into one bin for each document, and a means for stapling a bundle of sheets discharged to each bin, the number of sheets per document inputted by the input means described above is means for comparing the designated number of copies with a stapling limit set in advance; and means for warning that the designated number of copies exceeds the limit; The present invention is characterized in that when it is determined that the designated number of copies exceeds the above-mentioned limit number, the above-mentioned warning means is activated.

When it is detected by the action comparison means that the specified number of copies inputted exceeds the limit number of copies, the warning means is controlled to operate and a warning is issued, thereby preventing the operator from erroneously instructing the stapling operation. Since this eliminates stapling errors, it is possible to prevent stapling errors from occurring.

37 is a developing unit, 39 is a toner cartridge for replenishing consumed toner, and 40 is a drum shaft that rotatably supports the photosensitive drum 7.

Next, the operation of the copying apparatus having the above configuration will be briefly described. The photosensitive drum 7 is rotatably supported by a drum shaft 40 and rotates counterclockwise in response to a copy command or the like. Simultaneously with the rotation of the photoreceptor drum 7, a static elimination lamp 9-P is installed to prevent toner adhering to the photoreceptor drum 7 and uneven potential from reaching the charger 6 and the developing unit 37.
TC36, separation charger 27, transfer charger 28.
Eraser 5, cleaning unit 12. Bias roller 13. PCC 25 and quenching charger 11 are driven. After passing through the cleaning unit 12 and the static elimination lamp 9, the surface potential of the photosensitive drum 7 becomes zero.

The photosensitive drum 7 is driven by a main motor (not shown). At this time, the leading edge of the image is determined by the control section to be the part after the position passing the cleaning unit 12.

When the photosensitive drum 7 has rotated to the fixed position, the ADF 3
The original placed on the contact glass 4 by
Scanning mirror 15. Scanning is performed by a first carriage integrated with the illumination unit 14 and the like. The reflected light image is formed on the photosensitive drum 7 via the first scanning mirror 15, the second mirror 16, the third mirror 17, the lens 10, the fourth mirror, and the dustproof glass 2.

After the photoconductor drum 7 is charged by the charger 6, an eraser, that is, an erase lamp 5, illuminates unnecessary areas to create an image frame suitable for the transfer paper or the projected image, and then the photoconductor drum is A latent image is formed on 7. At this time, in order to obtain a same-sized image, the photosensitive drum 7 and the first carriage are driven at the same speed.

A developing unit 37 visualizes the latent image on the photosensitive drum 7 as a toner image. In this case, the developing unit 37
By applying a potential to 5.13, a dark or pale image can be obtained.

On the other hand, the double-sided paper feed tray 22. First paper tray 2
3. The transfer paper stocked in the second paper feed tray 24 or the third paper feed tray 33 is fed by the paper feed roller unit 29 until a paper detection (not shown) is activated.

Next, the paper feed roller unit 29 is operated again at the paper feeding timing, and the transfer paper is sent through the vertical paper transport section 30 or the horizontal paper transport section 32 to the registration rollers 35 that have been stopped in advance, and the toner image on the photoreceptor drum 7 is The registration roller 35 is driven at the timing when the leading edge of the transfer paper matches the leading edge of the transfer paper.

The toner image on the photosensitive drum 7 is transferred to a transfer paper by a transfer charger 28. At this time, the surface of the photoreceptor 7 is very smooth, and therefore the adhesion between the photoreceptor drum 7 and the transfer paper is large. Decreases adhesion to transfer paper. Next, the transfer paper is separated from the photoreceptor drum 7 by the separation claw 26, and the transfer paper thus separated is transferred to the fixing section 1 by the conveyor belt 21.
Send to 8. Heat and pressure are applied to the toner on the transfer paper sent to the fixing section 18, whereby the toner image on the transfer paper is fixed to the transfer paper, and then the transfer paper is passed through the reversing section 19 to a sorter. It is discharged at 20. When performing double-sided copying, etc., the double-sided paper feed tray 2 is
2.

Since a small amount of toner image remains on the surface of the photoreceptor drum 7 after transfer, the FCC 25 is activated and the surface is cleaned with the cleaning brush and cleaning blade in the cleaning unit 12, and the next quenching charger 11 and static electricity removal are performed. The lamp 9 makes the surface potential constant.

These control timings are mainly obtained from pulses generated in synchronization with the rotation of the photosensitive drum 7 or reference pulses for driving the photosensitive drum 7.

Next, the configuration of the sorter 20 of this embodiment will be explained based on FIGS. 2 to 8.

As shown in FIG. 2, an entrance guide plate 43 is provided at the receiving opening for copies discharged from the copying machine.

Following this, upper and lower conveyor belts 44, 42 and a switching claw 46 for conveying the copy upwards. Switching guide plate 45.47
is provided. A pair of paper ejection rollers 48, 4.9 and a paper ejection tray 54 are provided on the upper path formed by the switching claw 46, and a lower path formed by the switching claw 46 is provided upwardly in parallel to the 1-down direction. It follows a copy vertical feeding path along the copy insertion side of a bin 55 containing a plurality of copies (20 copies in the illustrated example).

A pair of rollers including a deflection claw 64, a conveyance roller 62, and a discharge roller 63 are provided at a position corresponding to each bin on the vertical feeding path, and a plurality of objects are thrown at appropriate intervals by the conveyance roller 62. The driven roller 6 is placed between the vertical copy feeding path.

And stack mode 1- (sort mode for each page)
If this is the case, the switching claw 46 is curved, and the copy switching guide plate 45 is conveyed downward along the lower copy switching guide plate 45. The copies conveyed by the first general feed roller 62 and the driven roller 65 are delivered four times to the bin 55 at the location where the deflection claw 64 is activated. The deflection pawl 64 performs a movement depending on the mode (saw l- or stack).

In the sort mode, the deflection claw 64 of the first bin operates and the second copy of the first page is ejected into the first bin 55, and the deflection claw of the second bin operates and the second copy of the first page is ejected into the second bin. Discharge at 55. Further, the first page of the second page is discharged to the first bin 55, and the second page is discharged to the second bin 55. In this way, when in sort mode, 1, 2, 3, etc. are stored in one bin.
...is discharged to the page.

When entering the stack mode 1, the deflection claw 64 operates so that all copies of the first page are delivered to the first bin 41i', and copies of the second page are delivered to the second bin 41E.

In this way, in the stack mode 1-1, 11 copies of the same page are put out in one bin, and they are sorted page by page.

In addition, if a copy jams near the deflection claw 64 during the saw 1 mode or the stack mode, the copy that is located at the position of the switching claw 46 will be ejected from the printer with a copy that is not the jammed copy. It has a function. This is possible by switching the switching claw 46 in the event of a jam, and then
is discharged to the 11 paper tray 54 without jamming.

The copies discharged onto the paper discharge 1-ray 54 can be placed in a predetermined bin by the manual feed table 52 or the manual feed roller 50 after the jam is removed.

In addition, in cases other than jams, when copies are inserted from the manual feed table 52, the copies can be ejected to each bin according to the drying tray 7 and sorted. The post-processing function that performs post-processing on copies sorted in this way will be described below.

The post-processing unit 61 degrades staplers, punchers, and the like. A post-processing unit motor 68 is used to move the post-processing unit to a position corresponding to each bin.

When the post-processing is executed from this state, the post-processing unit moving motor 68 is turned ON to lower the post-processing unit 61, and the bin position sensor 58 is set to ONL by the second bin position detection piece 59.

The post-processing unit moving motor 68 is turned off to stop the post-processing unit 61. Then, post-processing for the second bin is performed. When the execution of post-processing for the copy of a predetermined bin is completed, the four post-processing units 61 are moved to the home position. In this way, post-processing of a plurality of copy bundles can be performed.

FIG. 3 is a view from the opposite side of FIG.

In FIG. 3, things that could not be expressed in FIG. 2 will be explained.

The sorter of this embodiment is a 20-bin sorter, divided into two blocks of 10 bins each, and the upper block has a bin sensor 76.79.

There are paper discharge sensors 77 and 78, and sensors 81 and 84 and paper discharge sensors 80 and 83 are located in the lower block. Also,
The paper ejection tray 54 also has paper ejection sensors 98 and 99. These sensors are transmissive optical detection sensors consisting of LEDs and phototransistors. Paper ejection sensors 77, 78, 80 detect whether a copy has been ejected or not.
, 83°98.99, and the bin sensor determines whether there is a copy in the bin or not.
It is. This kind of pin sensor makes it possible to use the lower block if there is a copy on the upper block.

In order to perform copy post-processing, multiple copies must be aligned. Therefore, the sorter of the present invention is equipped with a jogger as described below.

The jogger driving belt 86 is rotated by the jogger moving motor 82 via the pulley 85, and the rotation shaft 96 is rotated. As a result, the jogger moving belts 73 and 88 move via the pulleys 74 and 87, and the shaft fixing unit 72 and shaft drive 95 fixed thereto move. Then, the size detection sensor 93 detects the minus of the predetermined size detection piece 92, and the jogger driving motor 82 stops. When the copy is ejected to the bin, the paper ejection sensor 77
．． 78 or 80 and 83 is detected, the alignment shaft drive unit 95 is activated, and the alignment plate 70 is moved by the alignment shaft 71 to align the copies. After finishing the post-processing, the jogger moving motor rotates in reverse and stops at the position where the home sensor 91 is turned on by the home detection piece 94. This position is the position for maximum size. In this way, each copy is aligned as it is ejected and is ready for post-processing operations.

FIG. 4 is a view from above of FIG.

The bin 55 has a notch so that the alignment shaft 71 can be moved to a position where minimum size copy alignment is possible. Also,
The alignment plate 70 rotates as shown by the arrow to align the copies.

○ Checks whether the set number of copies and the number of ejected sheets are equal (checks whether all copies of the negative original have been ejected), and if they have been ejected, the current bin is used for the first ejection operation. Turn off the deflection claw, turn on the bottle deflection claw for the first bottle of the block, and return.

(Explanation of post-processing flow) The post-processing flow is shown in FIG.

○ If it is in sort and stack mode, staple processing is performed for each bin and returns.

0 If the mode is not sort and stack mode, return without performing stapling processing.

Effects As described above, according to the present invention, when copies of the same document are output from a copying machine into different bins and stacked, and automatically bound with a stapler, the document 1
By issuing a warning when the specified number of copies per sheet, in other words, the number of stacked sheets per bin exceeds the stapling limit of the stapler, it is possible to prevent the operator from erroneously instructing stapling operations, thereby reducing mistakes. Staples can be prevented from occurring.
