Abstract

PURPOSE:To avoid doing such a meaningless job as stapling one copy alone by controlling a stapling signal by a command means so as to not to be generated at a time when the original through sheet number counted by a counting means is only one. CONSTITUTION:When there is no original, a conveyor driving motor is turned to OFF in wait for the original being discharged to a sorter. If a set sheet number is one with a stack mode, it is finished but not one, after-treatment by a stapler 61 is executed, thus its is finished. When it is original divided by 2 = 1 by single-double modes with a sort mode, it is finished but if not one each, the after-treatment by the stapler 61 is executed so that it is finished.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a post-processing control device for sheets discharged from a copying machine and sorted by a sorter.

To collate multiple copies of sheets from a multi-page manuscript in page order, the automatic document feeder feeds the manuscript in page order to the copying machine's manuscript reading section, and each page is This is done by making a required number of copies and discharging the copies one by one into each bin of a sorter in page order.

Devices for automatically stapling copies discharged from a copying machine in page order are well known, but it would be even more convenient if copies could be automatically stapled as they were discharged into each bin of a sorter in page order. Therefore, the present inventors have discovered that it is possible to eject copy sheets ejected from a copying machine into a plurality of bins one by one for each page, or to eject each copy of the same page into a separate bin, and to We have separately proposed a sorter that is equipped with a means to automatically staple the stack of copies discharged into a bin.

However, in a post-processing device (stapling device) for copies that are ejected in page order from a conventional copying machine, when stapling mode is selected, a stapling signal is sent after ejecting the sheets, regardless of the number of copies. stapling is performed. From this point of view, even in the sorter having the above-mentioned stapling function, stapling is performed even when only one copy is ejected to each bin, which is meaningless.

Problems to be Solved by the Invention An object of the present invention is to provide a sheet post-processing control device that prevents the problem of stapling being performed when only one copy is ejected to each bin in a sorter equipped with a post-processing device. shall be.

In order to solve the above-mentioned problems, the first invention of the present application provides an automatic document feeding means for automatically feeding a document to a reading position and automatically ejecting the document after reading the document. A means for copying a specified number of sheets per page onto sheets, a means for discharging the copied sheets of the above-mentioned M draft into a plurality of bins one by one for each page, and a means for discharging a sheet bundle discharged to each bin in page order. In a sheet post-processing control device having a means for stapling and a command means for instructing the stapling, a means for counting the number of originals fed by the automatic document feeding means and a number of originals counted by the counting means. Number of sheets passed is 1
The present invention is characterized in that control is performed so that the stapling signal is not generated by the command means at the time of .

In addition, as a second invention, when copying two single-sided originals onto both sides of one sheet and ejecting the copies to each bin of a sorter in page order and stapling, one-half of the number of passed originals is required. Control may be performed so that the stapling signal is not generated when the value is 1.

In addition, as a third invention, the number of copies is counted and this is calculated as original 1.
Since dividing by the specified number of copies per sheet gives the number of originals, control may be performed so that the stapling signal is not generated when the number is 1.

Furthermore, in the case of the sort mode in which copies of the same page are collected in one bin as the fourth invention, and in the case of the stack mode in which copies of the same page are collected in one bin, the number of copies ejected to each bin is counted and the number of copies is calculated as 1. In this case, the stapling signal may be controlled so as not to be generated.

Operation 1 By controlling as above, if only one sheet is output to each bin of the sorter, the stapling signal will not be generated even if the stable mode is selected, so the stapling signal will not be generated in each bin. It is possible to avoid the problem of staple binding of one sheet.

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

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 4o and rotates counterclockwise in response to a copying command or the like. Simultaneously with the rotation of the photoreceptor drum 7, a static eliminating lamp 9, PT
C36, separation charger 27, transfer charger 28, eraser 5, cleaning unit 12. The bias roller 13, PCC 25, and quenching charger 11 are driven. Cleaning unit 12 and static elimination lamp 9
After passing through, 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 is performed by a first carriage integrated with a scanning mirror 15, an illumination unit 14, etc. 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
A dark or light image can be obtained by applying a potential to.

On the other hand, the double-sided paper feed tray 22 and the first paper feed tray 2

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 the adhesion between the photoreceptor drum 7 and the transfer paper is therefore large. This reduces the adhesion between the paper and the transfer paper. Next, the transfer paper is separated from the photoreceptor tram 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 PCC 25 is activated and the surface is cleaned with the cleaning brush and cleaning blade in the cleaning unit 12, and the primary quenching charger 11 and static electricity are removed. The lamp 9 makes the surface potential constant.

These control timings are obtained mainly from pulses generated in synchronization with the rotation of the photoreceptor drum 7 or reference pulses for driving the photoreceptor 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, followed by upper and lower conveyor belts 44, 42 for conveying the copies upward.
, a switching claw 46, and switching guide plates 45, 4.7 are provided. A pair of paper ejection rollers 4 is provided on the upper path by the switching claw 46.
8.49 and a paper output tray 54 are provided, and the lower path by the switching claw 46 is the copy insertion side of a bin 55 that holds a plurality of sheets (20 sheets in the example shown) provided vertically parallel to the bottom. The copy follows the vertical feed path.

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 feed path, and a plurality of roller pairs provided at appropriate intervals of the conveyance roller 62 are used for copying. Driven roller 65 across the vertical feed path
are in pressure contact. The above-described conveyance belts 44 and 42, paper discharge rollers 48 and 49, conveyance roller 62, and discharge roller 63 are driven by a drive motor 41.

Shafts provided with two pulleys 53 and 69, respectively, at the upper and lower sides of the bin group are supported by the machine frame, and the lower shaft is connected to a motor 68 for moving the post-processing unit. upper and lower 2
A post-processing unit moving belt 66 is passed between the pair of pulleys, and a chuck unit 60 and a post-processing unit 61 are attached to these belts via a guide unit 51. In order to guide the guide unit 51, a guide rail 67 is provided on the side of the bin group in the vertical direction over the entire height of the sorter.

The copy discharged from the copying machine is inserted through the entrance guide plate 43, and is sandwiched between the pair of conveyor belts 42, 4.4.
It is transported to the upper part.

Now assuming that the mode is 1 normal paper ejection mode (a mode in which paper is ejected to the paper ejection tray 54), the switching claw 46 is lowered, and the copying is carried out along the switching guide plate: upper 47 by the paper ejection roller pair 48.
．． 49, the paper is discharged onto the paper discharge tray 54.

Also, now, sort mode (mode to sort into pages)
In the stack mode (a mode in which pages are sorted), the switching claw 46 is raised and the copy switching guide plate is conveyed downward along the lower copy switching guide plate 45. The copy transported by the transport roller 62 and the driven roller 65 is
It is discharged into the bin 55 at the location where the deflection claw 64 is activated. The deflection claw 64 performs a movement appropriate to the mode (sort or stack).

In the sorting mode, the deflection claw 64 of the first bin operates and the second copy of the first page is ejected to the first bin 55, and the deflection claw of the second bin operates and the second copy of the first page is ejected to the second bin 55. to be discharged. 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 output to pages like this.

When in stack mode, all copies of the first page are
The deflection pawl 64 operates to cause the copy of the second page to be ejected into the second bin.

In this way, in the stack mode, copies of the same page are ejected into one bin and sorted by page.

Additionally, if a copy jams near the deflection claw 64 during saw 1 mode or stack mode, there is a function to eject the copies in front of the switching claw 46 from within the sorter for copies after the jammed copy. . In this case, when a jam occurs, the switching claw 46 is switched, and the copy that comes later is discharged onto the paper discharge 1-ray 54 without causing a jam. The copies discharged to the paper discharge tray 54 can be placed into a predetermined bin by the manual feed roller 50 from the manual feed table 52 after the jam is removed.

In addition, even in cases other than jams, when copies are inserted from the manual feed table 52, the copies can be ejected to each bin and sorted according to the mode. Regarding the post-processing function that performs post-processing on copies sorted in this way,
This will be explained below.

The post-processing unit 61 means a stapler, puncher, etc. In order to move the post-processing unit to a position corresponding to each bin, the post-processing unit motor 68 is rotated, and the post-processing unit moving belt 66 is moved up and down via the pulleys: lower 69 and upper 53, and the guide The rail 51 is moved up and down. The guide unit 51 has a car and is adapted to move along a guide rail 67.

The chuck unit 1-60 is a device that transports the copy bundle to the position of the post-processing unit 61 and returns it to its original position after performing post-processing.

In FIG. 2, the home sensor 5 is detected by the home detection piece 57.
6 is turned on, and post-processing can be performed on the copy of the first bin.

When post-processing is executed from this state, the post-processing unit moving motor 68 is turned on after the post-processing unit 61-
is lowered, and the bottle position sensor 58 is turned on by the second bottle position detection piece 59.

The post-processing unit movement motor 68 is turned off to stop the post-processing unit (after execution)-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 post-processing unit 61 is 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, and is divided into two blocks of 10 bins each, with bin sensors 76, 79, and paper discharge sensors 77, 79, 79, 79, and 10 bin sensors in the upper block.
78, and the lower block has sensors 81.84 and paper ejection sensors 80.83. Further, the paper ejection tray 54 also has paper ejection sensors 98 and 99. These sensors are
It is a transmission type optical detection sensor consisting of an LED and a phototransistor. The paper ejection sensor 77.78, 80, 83°98.99 detects whether the copy has been ejected or not.
The bin sensors 76, 79, 81 and 88 determine whether there are copies in the bin or not. 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.

A jogger drive belt 86 is rotated by the jogger moving motor 82 via a pulley 85, and a drive shaft 96 is rotated. As a result, the jogger moving belts upper 73 and lower 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 drive motor 82 stops. Then, when the copy is ejected to the bin, the paper ejection sensor 77.
78 or 80 and 83 are detected, the alignment shaft drive unit 95 is activated, and the alignment plate 7o is moved by the alignment shaft 71 to align the copies. and.

After finishing the post-processing, the jogger movement motor rotates in reverse.

It 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 the minimum size copy alignment is possible. Also,
The alignment plate 70 rotates as shown by the arrow to align the copies.

At this time, an end face pressing plate 97 is provided to hold the other end of the copy in a fixed position.

This end face pressing plate 97 is adapted to move in accordance with the movement of the chuck unit 60.

Finally, we will explain the flow of an embodiment of the fourth invention in which the number of copies discharged into each bin is counted regardless of whether it is in the sort mode or the stack mode, and if the number is 1, the stapling signal is not generated. explain.

In addition, in the subroutine, r Cerato number input cuff flow J,
Since "r sorter mode set flow" and "r post-processing flow" are the same as those in the first embodiment of the invention, only the overall operation and the flow of subroutines other than those described above will be illustrated and explained.

(Overall operation explanation) The overall operation flow is shown in FIG. 19.

0 Input the set number from the numeric keypad using the set number input routine.

0 Select sort or stack mode.

It remains in a wait state until the O start key is pressed.

○ Check whether it is in sort and stack mode,
If it is in the sort and stack mode, the switching claw 46 is raised so that the copies are transported to the bin side, and if it is not in the sort and stack mode, the switching claw 46 is lowered so that the copies are discharged to the paper output tray side.

○ Turn on the transport drive motor.

01 Clear the counter for the number of sheets discharged per bin.

Below is an explanation of the flow when using the ADF. If an original is set on the OADF, an original feed signal is sent to the ADF, and the original is set at a copyable position on the contact glass.

0 Clears the copy number counter and ejected paper number counter.

○ Perform the copy operation.

0 Controls ejection of created copies according to sort or stack mode.

0 Repeat the copying operation until the number of copies reaches the set number.

A document discharge signal is sent to the OADF to discharge the document on the contact glass.

0 If there is still a document, feed the next document and repeat the above copying operation.

If there is no original document, wait until it is discharged to the sorter, and then turn off the conveyance drive motor.

0 If the number of sheets ejected per bin counted up by the ejection control is 411 II, the process ends without performing post-processing.
If it is other than "1", staple post-processing is executed and the process ends.

The following is an explanation of the flow when the ADF is not used.O Clear the copy number counter and ejected paper number counter.

O Perform copying operation.

Q Controls the ejection of copies made according to sort or stack mode.

0 Repeat the copying operation until the number of copies reaches the set number.
