Abstract

PURPOSE:To eliminate necessity of aligning at once sheets to a plurality of pins, to effectively align the sheets by a small-sized motor having a small torque and a low cost, and to then perform a stapling operation by providing control means for operating sheet aligning means for the sheets even after the sheets are bound by staple means. CONSTITUTION:The pressing elastic member 502a of a pressing member 502 is brought into contact with one side end face of a sheet bundle by oscillating, and the end face of the opposite side of the bundle is pressed to a fence 316 side. As a result, the position of one side end face of the bundle is aligned, the other side end face having a perpendicular relation to the one side end face of the bundle is so pressed toward a direction of an arrow A as to be brought into contact with a pin rising part 308 by the oscillating force of the member 502, and the other side end face of the bundle is aligned. In this case, since the oscillation is performed by normal and reverse rotations of an oscillating motor 520, even if the sheets are not pressed by the normal rotation, they can be easily returned to home positions by the reverse rotation. The sheets discharged on a bin 300 can be desirably aligned to the end by the above operation.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a filter paper processing device installed in a copying machine, a printing machine, etc.

[Conventional technology]

Transfer paper on which an image has been formed or paper (sheet) on which printing has been completed
Generally, a predetermined number of copies of such books are stacked on each pin of a sorter or stacker, and the stacked bundles are taken out from each pin and bound with a stapler, or punched with holes and fastened with a zipper. It is bound or bound with glue. However, in order to bind the sheets M discharged onto the pins, it is inefficient and troublesome for the operator to take them out from each pin and perform the prescribed processing. A sorter that performs prescribed processing, that is, stapling,
Paper processing devices, also referred to as staplers, are becoming popular.

A typical paper processing device of this type is JP-A-62-2
90655, JP-A-62-290677, JP-A-63-
As disclosed in JP-A No. 6087) and JP-A-63-1) 6168, each pin is stapled after a preset number of sheets have been discharged to all the pins.

In this case, in order to perform stapling, the copied sheets ejected onto the pins must be aligned, otherwise the sheets may be stapled in pieces, and complete paper binding cannot be performed. Generally, it has a function to align the ejected paper. Regarding this waste paper and stapling operation, in order to improve productivity during stapling, the copy paper of the final original is placed on the first pin without waiting until the preset number of sheets are ejected from all the pins as described above. It is also conceivable to set the stapling operation to start from the first pin when the paper is ejected and alignment is completed.

Furthermore, conventionally, in paper processing apparatuses equipped with a so-called dual sort type sorter device having first and second sorter means for receiving sheets discharged from the apparatus main body and distributing them to a plurality of pins, It is possible to sort paper of different sizes, but if you also have dual alignment methods,
The configuration becomes complicated and the cost increases. Therefore, the paper waste removal means is configured to arrange all the paper pins at once. For this reason, it is no longer possible to arrange sheets of different sizes. Of course, it goes without saying that there is no point in stapling a stack of paper with incomplete alignment.

[Problem to be solved by the invention]

By the way, in the above-mentioned conventional technology, multiple pins are divided into two blocks and sorted/stapled/stapled in an endless manner.
In the dual sort/stapling mode, the position of the sheets on the pins varies in the first block due to the operation of the stapling means, and the sorted sheets in the second block may not be aligned properly. There was a problem that the process was not completed completely due to variations in the paper in the first block.

Further, the above-mentioned conventional technology has a problem of poor operational efficiency because it is not possible to perform dual sorting on sheets of different sizes.

Furthermore, before sorting copies into all the preset pins, if the transfer paper breaks while copying the final original and it is not possible to sort into all the pins, the last ejected pin Perform stapling until After replenishing the transfer paper, copying and stapling will be continued, but before stapling, it is necessary to perform alignment. For this reason, alignment is also performed on the pins for which stapling has been completed before replenishing the transfer paper, but as mentioned above, the pin-like placement positions of the stack of paper after stapling vary, so the pins are aligned. As the number increases, the load on the motor that drives the alignment device increases, and a large torque motor must be prepared in preparation for this. However, such motors are not only expensive but also often large.
There is also the problem of being disadvantageous in terms of space factor.

Therefore, a first object of the present invention is to provide a paper processing apparatus that can reliably align sheets and perform a stapling operation.

A second object of the present invention is to provide a filter paper processing apparatus that can sort sheets of different sizes.

A third object of the present invention is to provide a paper processing device that can perform sufficient paper alignment using a small motor with low torque, low cost, and no disadvantage in terms of space factor.

[Means to solve the problem]

The first and third objects are, in a paper processing apparatus having a plurality of pins, an aligning means for aligning sheets discharged onto these pins, and a stapling means for stapling the sheets on each pin; This is achieved by providing a control means that operates the aligning means for the sheets even after the sheets are bound.

The second purpose is to provide first and second sorter means for receiving sheets ejected from the device body and distributing them to a plurality of pins, an aligning means for aligning the ejected sheets to each pin, and a means for aligning the sheets ejected to each pin. A paper processing apparatus having a stapling means for binding sheets, a size information detection means for detecting size information of the sheets discharged to the first and second sorter means, and a size information signal of the sheets discharged from the device main body. The apparatus comprises at least one of size information signal detection means received from the apparatus main body, and when the size information of the paper in the first and second sorter means from the size information detection means or the size information signal detection means is different,
This is achieved by providing a control means for inhibiting the operation of the stapling means.

Specifically, the control means in the second means is controlled by the size information so that the size of the paper discharged to the first sorter means is determined based on the size of the paper discharged to the first sorter means during the discharge to the second sorter means. When it is found that the size of the sheets discharged to the second sorter means is small, the stapling means is set to prohibit the operation of the stack of sheets discharged to the second sorter means, and/or the stapling means When it is found that the size of the paper discharged to the first sorter means is smaller than the size of the paper discharged to the second sorter means, the first sorter means This is done by setting the stapling means to prohibit the operation of the stack of sheets discharged at the same time.

The second object is to provide first and second sorter means for receiving sheets discharged from the main body of the device and distributing them to a plurality of pins, an aligning means for aligning the sheets discharged to each of the pins; A paper processing apparatus having a stapling means for stapling sheets of paper with pins, size information detection means for detecting size information of sheets discharged to the first and second sorter means, and size information of sheets discharged from the main body of the device. At least one of size information signal detection means for receiving a signal from the device main body is provided, and when the size information of the paper in the first and second sorter means from the size information detection means or the size information signal detection means is different. This can also be achieved by a third means comprising a control means set so as not to operate the aligning means.

Specifically, based on the size information, the control means in the third means is controlled to have a second size smaller than the size of the sheets discharged to the first sorter means during the discharge of sheets to the second sorter means.
by setting the aligning means not to operate on the stack of sheets discharged to the second sorter means when it is found that the size of the sheets discharged to the second sorter means is small, and/ Or, when it is found that the size of the paper discharged to the first sorter means is smaller than the size of the paper discharged to the second sorter means during the paper discharge to the first sorter means, the above-mentioned This is done by setting the alignment means not to operate on the bundle of sheets discharged to the first sorter means.

[Effect]

According to the first means, even after the sheets are stapled by the stapling means, the paper aligning means can be operated to perform alignment on the sheets, so alignment is not performed every time multiple pins are attached. This makes it possible to align paper using a small torque motor. In addition, when performing sorting and stapling processing in multiple systems, even if the other system is used to sort after processing one system, after the final paper alignment of the pin block of that one system is performed, the pins of the other system Since alignment can be performed in blocks, alignment and binding operations for two types of paper can also be performed reliably.

According to the second means, the size information detection means detects the sizes of the sheets discharged to at least two sorter means, or the size information detection means receives size information of the sheets discharged from the main body of the device. However, when it is found that the sizes of sheets in each sorter means are different, the operation of the stapling means is prohibited, so that sheets of different sizes can be reliably sorted. At this time, it is also possible to staple sheets of a desired size using the third or fourth means.

According to the fifth means, the size information detection means detects the sizes of the sheets discharged to at least two sorter means, or the size information detection means receives size information of the sheets discharged from the device main body. However, if it is found that the sizes of the sheets in each sorter means are different, the alignment operation is not performed, so even if the sizes are different, sorting can be performed as is.

At this time, the sixth or seventh means can align the sheets of the desired size.

The deflection claw 164 performs a movement that matches the mode (sort or stack).

In the sort mode, the deflection claw 164 of the second pin operates and the second copy of the first page is ejected to the first pin 300, and the deflection claw 164 of the second pin operates and the paper is ejected to the second pin 300.

When in stack mode, all copies of the first page are
The deflection pawl 164 operates to eject the copy of the second page onto the second pin. In this way,
In stack mode, copies of the same page are ejected to one pin and are sorted by page.

The configuration required to staple copies sorted in this manner will be described below. To perform copy stapling, multiple copies must be aligned. Therefore, the sorter of this embodiment is equipped with a swinging device, which will be explained below with reference to FIGS. 4 to 8.

FIG. 4 is a perspective view schematically showing the swinging device, and FIG. 5 is a plan view showing the relationship between the swinging device and the pin 300.

A pin fence 16 is erected on one side edge of each pin 300, and this pin fence 31
On the other side edge that is orthogonal to the edge where 6 is provided,
A pin rear end rising portion 3G8 is provided upright. Further, a notch 31) is provided on the edge opposite to the edge where the pin fence 316 is provided. This notch 3
1) is provided so as to extend over a predetermined length toward the fence 316. Each of these pins 300
A main shaft 501 having a rectangular cross section is erected so as to vertically penetrate through each notch 31) provided in the main shaft 501. Each pin 30 is located in the middle of this main shaft 501.
A plurality of pressing members 502 are attached at positions corresponding to 0 for aligning the sheet stack by contacting the end surface of the sheet bundle. As shown in FIG. 6, each of these pressing members 502 includes a pressing elastic member 502a facing the fence 316.

502b is provided. Then, due to the elasticity of the pressing elastic member 502a, the pressing member 502 and the heel 300
The installation is designed to absorb the above variations. Further, when the paper curls upward, the curl of the paper is suppressed by the pressing elastic member 502b, and the pressing member 502 reliably contacts the end face of the sheet bundle to align the position.

Further, pieces of brackets 505 and 506 formed in an L shape are attached to the upper and lower ends of the main shaft 501, respectively, and the notch is provided in the upper and lower regions of the pin 300. 31
) Extending in substantially the same direction as the timing belt 5
07 and 508 are respectively arranged. and,
The other pieces of each bracket 505 and 506 are fixed to each of these timing belts 507 and 508, respectively. Each timing held 507 and 5 above
Boo IJ509.510 with 08 hung on each
．． Of the pulleys 51), 512, and 513, the drive-side pulleys 509 and 51) are respectively fixed to both ends of a drive shaft 514 that is provided to extend in the vertical direction. The lower timing belt 508 is hung around a pulley 513 provided on the output shaft of a size moving motor 515.

As shown in FIG. 4, the position of the pressing member 502 is between the size detection plate 530 fixed to the sorter and the lower bracket 50.
Size detection sensor 53 which is size information detection means on 6
1, it is detected.

A swing motor 520 is installed on the lower bracket 506, as shown in FIG. This swing motor 52
An eccentric shaft 520a is provided at the output section of 0 so as to protrude upward. On the other hand, a swing arm 521 is attached to the lower end of the main shaft 501 so as to protrude toward the swing motor 520 side. The eccentric shaft 520a is loosely fitted into a long groove 521a formed in the swing arm 521. Therefore, as the swing motor 520 rotates, the swing arm 5
21 is oscillated, and the oscillating force is transmitted to the pressing member 502 corresponding to each pin 300 via the main shaft 501, and each pressing elastic member 502a of this pressing member 502 is moved to the position shown by the solid line in FIG. As shown in FIG. 8, it swings sinusoidally between the position indicated by the dashed line and the swing speed becomes slower at the epithelial point. Further, the position indicated by the dashed line of the pressing elastic member 502a is set so as to have a certain biting depth from the sheet end surface in order to reliably press the sheet bundle against the fence 316.

As described above, the swinging device 500 is unitized so that the entire swinging unit can be moved by the size movement motor 515.

When the swinging device receives the size signal sent from the image forming apparatus side, the upper and lower timing belts 507 and 508 are conveyed by the size movement motor 515, and the pressing member 502 attached to the main shaft 501 is thereby moved toward the paper sheet. It moves forward toward one end of the bundle. Then, a size detection plate 530 and a size detection sensor 531
to move the swing unit to a predetermined position.

Next, the swing motor 520 rotates forward half a turn (180'), then reverses and returns to the home position, causing the swing arm 521 to swing once, and the swing force is transmitted through the main shaft 501. It is transmitted to each pressing member 502. As a result, the pressing elastic member 502a is swung from the position shown by the solid line in FIG. 5 to the position shown by the dashed line. Further, as shown in FIG. 9, the swing motor 520 rotates normally for 1806 degrees or more, and then reverses and returns to the home position, thereby easily swinging twice in one process.

As a result of the above-described swinging, the pressing elastic member 502a of the pressing member 502 comes into contact with the end face of one example of the paper bundle, and the opposite end face of the paper bundle is pressed against the fence 316 side. One side end face of the bundle is aligned, and the other end face, which is orthogonal to the end face of one example of the paper bundle, is moved in the direction of arrow A by the swinging force of the pressing member 502 so that it comes into contact with the pin upright portion 308. As a result, the other end surface of the paper bundle is aligned.

Therefore, the sheet stack is well aligned in both directions. In this case, since the rocking is performed by normal rotation and reverse rotation of the rocking motor 520, even if the sheet cannot be pushed completely by normal rotation, it can easily return to the home position by reversing.

With the above operation, the sheets discharged onto the pins 300 can be aligned well to the edges.

The aligned sheet stack is taken out in the direction of arrow X in FIG. 5 after various post-processing operations such as stapling are performed. Since there is nothing in this direction that would impede the paper removal, the paper removal operation can be easily performed.

Further, the pins 300 have been devised in various ways to facilitate paper alignment and stapling.

Hereinafter, the structure of the pin 300 will be explained based on FIGS. 10 to 28. Fig. 1O shows a plan view of the pin 300, and Fig. 1) shows a side view. A notch 31) located approximately in the center of FIG. 1O is for allowing the main axis of oscillation to move in accordance with the paper size.

Two convex portions 301 located next to the cutout portion 31)
is a rocking plate 502 attached to the rocking main shaft 501.
(Fig. 15) is used to create a groove into which the hole (Fig. 15) is inserted. As shown in FIG. 15, by providing the convex portion 301, the paper P is lifted up, and the paper P can be reliably brought together during rocking.

A similar effect can be obtained by providing a recess 321 as shown in FIG. 17.

Furthermore, if a convex portion 301 is provided as shown in FIG. 15, it will simultaneously perform the role of stiffening the ejected paper P, and will also have the effect of allowing the paper P to be swung and aligned well.

The rib 302b of the pin 300 allows the ejected paper to fit into the notch 3.
1) is taken into account.

FIG. 13 is a sectional view of the rib 302b near the notch 31). As can be seen in FIG. 13, the rib 302b is connected to pin 3.
It protrudes above and below 00, and prevents the sheets P to be stacked from slipping under, and at the same time, from entering the notch of the upper pin. Said rib 302
The arrangement of b is also set within lQmm from the edge of the paper size, and is designed to reliably guide the edge of the paper that is particularly likely to enter the notch 31).

In addition, in FIG. 13, the shape of the rib on the upper side of the pin forms a gentle triangular shape on one side. This is because when the stack of chucked papers is stapled and then discharged, the discharged paper P is This is to guide the guide so that it does not get caught on ribs such as 302b. The rib 302b is a low rib near the pin rising portion 308, as shown in FIG. 14, for example, and gradually becomes higher up to the notch. This is to ensure a large number of sheets can be loaded.

In order to increase the number of copies that can be loaded, a static elimination brush 322 is attached to the pin 300 of this embodiment, as shown in FIG. There are 8 dangers that adversely affect alignment. However, by providing the ribs 302c, the ejected paper P can be reliably guided so as not to be caught by the static elimination brush 322, thereby solving the above problem. Also, this rib 302C is also
The arrangement is such that both ends of each size are held down.

In Figure 1), the rib 302e protruding from the bottom is the first rib 302e.
As shown in Figure 8, it serves to hold down the end surface of the paper P, and when the chuck unit moves forward, the chuck lever 421 can reliably chuck curly paper without hitting the loaded paper P. .

Guide member 317 attached to pin 300 in FIG.
is a member that guides the paper P stacked on the pin 300 so that it reliably enters the opening 323 of the stapler section when the paper P is moved to the stapler section by the chucking section. Without this guide member 317, as shown in FIG. 22, there is a risk that the paper P will be caught in the stapler opening 323 when moving from ■ to ■ in FIG. This problem occurs particularly when the paper P has a large curl as shown in FIG. 19 or when the number of stacked sheets increases.

However, by attaching the guide member 317, the paper P can be reliably guided to the stapler opening 323 in the state shown in FIG.

The convex portion 307 protruding from the lower side of the pin 300 in Figure 1) is for suppressing the curl of the paper P. The sheets P discharged onto the pins 300 are aligned in one direction, but highly curled sheets P may climb over the pin fence 316 (FIG. 12) provided on the side of the pins, impairing the alignment. The convex portion 307 is installed to prevent the paper P from curling, etc., and to ensure good alignment. FIGS. 23 and 24 show model cases with and without the curl presser 307. The states of ■, ■, and ■ of the paper P in the figure indicate the states of the paper P over time in a stepwise manner when the paper P is aligned.

The notch 310 shown in FIG. 10 is a notch through which the chucking part chucks the sheets P aligned on the pins 300.

The pin 300 is attached to the sorter section at an angle. This aligns the ejecting direction of the ejected paper P,
This is done by the rotational oscillation of the oscillating plate 502 and the fall of the paper P under its own weight, and for example, in this embodiment, the tilt is 25''.

In order to improve alignment accuracy in the ejection direction and stackability, the shape of the rising portion 308 of the pin 300 is as shown in FIG. 25. An arbitrary perpendicular part is provided to the bottom surface of the pin 300, and from its extension 90 degrees to the bottom surface of the pin 300.
``A more acute-angled portion is provided. This is to suppress curls, etc. at the bent portion B when sheets P are loaded on the rising portion 308, align them with the mover, and stack them. FIG. 26 shows a state in which sheets are stacked.

FIGS. 27 and 28 show a state in which the rising portion only extends vertically, and a state in which sheets P are stacked. With this shape, when curled paper is ejected, the curl cannot be suppressed and the rising portion 308a
The paper P starts to ride on the paper P, causing problems such as jams.

FIG. 12 is a right side view of the pin 300, showing the receiver attached to the stand. In the same figure, 315a, 31
5b indicates a side plate, and 312a and 312b indicate pin holder stands. The pin receiver on the pin fence 316 side of the pin 300 is fixed to the stand 3f2a, and the pin receiver on the other side is supported by the stand 312b with a slight gap. In this case, by fixing the pin fence 316 side, the position of the staple can be prevented from varying. Also, the pin holder is on stand 3.
The small gap provided on the 12b side is for absorbing thermal expansion of the pin 300.

Next, the stapler device 400 will be explained.

In 400, a stapler 401 and a paper pulling device 402 are each fixed to hang from the lower surface of a plate-shaped bracket 403. The stapler 401 is used to drive staples into each of the later sorted paper bundles that are deposited on each pin 300 (not shown), and the paper pulling device 402 is used to staple the paper stacks on each pin 300 (not shown). It can be grasped and moved in a horizontal direction.

The stapler 401 and the paper pulling device 402 are mounted in the groove of the pin 405b so as to be moved vertically, so that the stapler 401 and the paper pulling device 402 are integrally reciprocated in the vertical direction along the sides of each pin 300. It has become. Additionally, two drive belts 406a, 406b are stretched substantially parallel along the sides of the pin 300. The bracket 403 is connected to these drive belts 406a, 406b.
Both end edge portions 403a and 403b are fixed with screws, respectively. Each of the above drive bells) 406a.

406b indicates two booleans arranged vertically apart from each other by a predetermined distance.407a, 407c and 407b, 40
Kake is passed between 7a.

The lower pulleys 407c and 407d are connected by a common shaft 408 so as to rotate together.

The rotational driving force of the drive motor 409 is transmitted to a pulley 412 via a pulley 410 fixed to the output shaft and a power transmission heald 41), and is meshed with a drive gear 413 fixed on the same axis. gear 4
14 in order, and is transmitted to a drive pulley 414 fixed to one end of the support shaft 408. With such a driving force transmission mechanism, the driving healds 406a, 40
6b is conveyed and driven, thereby the stapler 401
Then, the paper pulling device 402 moves in the vertical direction.

Furthermore, a position sensor 415 is attached to one edge portion 403a of the bracket 403, and a detection plate 416 is erected between the position sensors 415. The detection plate 416
, projections 416a for indicating positions are formed at predetermined intervals so as to correspond to the positions of each pin 300. With such a position detection mechanism, the stapler 4
01 and the paper pulling device 402 are controlled to be stopped at the positions where each pin is installed.

The protrusion 403C and sensor 403d in FIG. 29 are for determining the upper limit position of the bracket 403,
When 403C enters sensor 403d, motor 409
stop rising at

FIG. 31 is an explanatory diagram to make the movement of the stapler device 400 described above easier to understand, and the movement of the paper 423c discharged onto the pin 300, the movement of the chuck section 421, and the position of the stapler 401 will be explained.

The paper 423c discharged onto the pin 300 is discharged to a position shown by 423d. Thereafter, it is aligned to a position where it abuts against the fence 316 using a swinging device that will be described separately. After that, when copying is finished and stapling is started, the chuck part 421 moves from the position shown by the solid line to the position shown by the dashed-dotted line, closes the chuck part 421, pinches the cover 423C, and returns to the position shown by the solid line. Due to this operation, the paper 423C becomes 42
Move to position 3r and attach pin 300 to stapler 401.
A certain number of sheets are stapled on top. After that, the chuck part 421 is opened, and the paper 423C is 423
It is returned to the range from the position e to the position 423d. This completes the work for one pin 300, and the work for the next pin 300 is completed.
Go to 0 and repeat this operation. The details of their operation will be explained later. The above-mentioned paper pulling device 4
02, as shown in FIG. 32, includes a chuck part 421 that grips a bundle of sheets, and a reciprocating mechanism 422 that reciprocates this chuck part 421 in a substantially horizontal direction. In the chuck portion 421, a pair of swinging arms 4212 and 421S are swingably attached to the substrate 421a, and the swinging arms 421z and 421S are swingably attached to the substrate 421a.
When s is activated by the solenoid 421C, the chucks 421y and 421m operate to grip the paper.

The reciprocating mechanism 422 is provided with a feed shaft 422a that moves the chuck section 421 forward and backward toward the east side of the sheet.

Both support shafts protruding from both ends of the feed shaft 422a are rotatably supported by both pieces of a U-shaped frame 422b. One side of each support shaft of the feed shaft 422a penetrates a portion of the frame 422b and further protrudes by a predetermined amount, and a pulley 422C is fixed to the protruding portion, as shown in FIG. Two round belts 422d are hung on the boob.

As a result, the feed shaft 422a is connected to the relay pulley and the gear 4.
It is driven by a drive motor 422r via 22e.

Further, a feed screw portion constituting a ball screw is engraved on the outer peripheral surface of the feed shaft 422a, and a boss portion 421h is fixed to the substrate 421a side with respect to the feed screw portion.
are screwed together. That is, the feed shaft 422a is rotationally driven by the output of the drive motor 422f, and the substrate 421a is reciprocated by this rotational force.

Furthermore, two position sensors 422j and 422k are installed on the frame body 422b at a front position and a rear position, respectively, separated by a predetermined distance, and the boss part 421h
A detection plate 422m as a detection target for both the position sensors 422j422 is erected on the side, and the chuck part 42 is located between the position sensors 422j422.
1 moves back and forth.

In the embodiment having such a configuration, when the stapling mode is started, first the drive belt 4 shown in FIG.
06a and 406b move the stapler 401 and paper pulling device 402 up and down integrally, and the stapler 401 and paper pulling device 402 are transported toward a predetermined pin 300 on which a stack of sheets to be stapled is deposited, and the stapler 401 and paper pulling device 402 are moved toward a predetermined pin 300 where a stack of sheets to be stapled is deposited. Based on the signal from the sensor 415, it is stopped at a position close to a predetermined pin 300.

At this time, solenoid 421C is turned off,
Therefore, both swing arms 4212.421S and chucks 421y, m are placed in an open state. next,
The feed shaft 422a is rotationally driven by the output of the drive motor 422, and the chuck section 421 moves forward toward the paper stack by this rotational force.
It is a figure which shows the groove part 430 carved in the outer peripheral surface of. The ball 431 that has entered the groove 430 is guided by the groove 430 by the rotation of the feed shaft 422a and reciprocates. Both ends of the feed shaft 422a are idling portions 43 of 180° or more.
2 is provided, and the groove end of the idling portion 432 serves as a stopper, eliminating variations in the stop position due to rotational inertia.

By using the round belt 422d for the drive transmission method described above, the impact when the belt 431 hits the groove end can be absorbed by slipping, and problems caused by the impact can be eliminated. In this embodiment, the explanation was given using the round belt 422d, but
The same can be said of other friction transmission methods such as flat healds.

FIG. 51 is a developed view showing another embodiment of the groove shown in FIG. 45. In the figure, speed control during movement is performed by changing the amount of advance relative to the rotation angle. That is, in the case of this example, the total amount of movement is 2 rotations (720 degrees), and if the amount of movement A is 42 mm,
Movement iB when rotated 906 times = 3mon, movement amount C when the next 90° rotation is made = 4mm, movement iD when the next 90° rotation is made = 6mm, movement amount E when the next 90° rotation is made =
It is gradually accelerated during the first rotation of 7 mm, and then decelerated during the next rotation at the same rate as the acceleration during the previous rotation and then stopped. FIG. 52 is a graph of the above explanation. By performing the above speed control, the chuck section 421 chucks the aligned paper bundle 423C into the chuck 421y.
, 421m to prevent the stack of sheets 423C from becoming uneven due to inertia at the time of starting and stopping when returning to the stapling position.

When the chucks 421y and 421m move to a position where they can grip the stack of sheets, they stop there, and at the same time, the solenoid 421C is turned on.

Chuck 42 is turned on by turning on solenoid 421C.
1, Y, 42]m is closed as shown in FIG. 35, and the edge portions of the paper bundle are gripped by chucks 421y and 421m.

The movement at this time will be specifically explained based on FIGS. 32 to 38. The device moves from FIG. 32.34 to the state of FIG. 3536. That is, when the solenoid 421c is turned on, the lever 421+2 rotates about the fulcrum 421d. Lever 4
21) by the spring 421k hooked on the lever 42
1j rotates clockwise using 421W as a fulcrum. In addition, a gear A421g is fixed to the lever 421j,
And since it meshes with gear B421w, movement is transmitted. The gear B421w is fixed to the upper lever 421z, and the upper lever 421z rotates counterclockwise using 421x as a fulcrum, and moves downward at 421.
Chuck supported by 21L: Upper part 421y moves downward. Moreover, since the chuck part is in a state of protruding forward, the pin 421v falls into the notch 422W of the return plate 422z, as shown in FIG.

Also, since the gear B421W meshes with the gear C421)), the gear C421p also rotates clockwise, and the lower lever 421S fixed to it also rotates clockwise around 421'' as a fulcrum, and the shaft at 421n. Supported chuck: lower 42
1 m moves upward as shown in FIG. The spring 421f pulls the lower lever 421S counterclockwise, but it moves like this because it is weak.

The movement distance from the fixed position of chuck: upper 421y and chuck: lower 421m is gear A421g, B42IW, 421p.
It is determined by the number of teeth and the length of the rotation fulcrum and the point of action.

In this example, the number of teeth of gear A421g is 40° gear B4
Since the number of teeth of 21w is 32 and the number of teeth of gear C421p is 56, if the amount of movement of each gear is expressed as a ratio, A
:B:C=1:1.25:0°7. Also lever:
The distance between the fulcrum 421X of the upper 4212 and the point of action 421L is 5
2mm, lever: fulcrum 421r of lower 421s and point of action 4
Since the distance to 21n is 37 mm, the movement ratio is l.

It becomes 25X52:0.7X37, and moves at a ratio of 2.5:l. In other words, when the chuck 2 upper moves down by 2.5, the chuck lower moves by 1.

Further, the chuck force of the double chuck, lower portions 421y and 421m, is determined by the force of the spring 421 attached to the solenoid 421C.

As you can see in Figure 32, double chuck, bottom 421)
As the thickness between 421 m increases, the spring 421 stretches. In other words, the chuck force is designed to increase as the number of sheets held by the chuck unit 421 increases, thereby eliminating problems such as displacement due to insufficient chuck force.

Next, by reversing the drive motor 422f, the chuck portion 421
is moved back to its original position as shown in FIG. 37 while gripping the paper stack, and thereby the paper stack is translated in a substantially horizontal direction and drawn toward the stapler 401. When the edge portion of the recording paper bundle is transported to a position where it can be stapled, it is stopped there.

FIG. 34, FIG. 36, and FIG. 38 are views in which the return plate portion is visible.

At this time, since the return plate is caught by the notch 422W and the pin 421V, the return plate is moved to the position shown in FIG. 38 by the reverse rotation of the motor. Return plate 422Z is return plate bracket) 4
Insert the pin provided in the return +7it422z into the notch 422t of 22x, and insert the pin provided in the return plate 4222 into the notch 422r.
A pin 422p provided with a return plate bracket 422x is inserted.

Further, the return plate bracket 422x is fixed to the frame 422b, and the return plate bracket 422x and the return plate 422
z is engaged by a spring 422n. Therefore, the return plate 422z is moved to the 36th position by the reverse rotation of the drive motor 422f.
The figure shows the state shown in FIG. 38, and the return plate 4222 itself is pulled leftward in FIG. 38 by a spring 422n. Thereafter, the stapler 401 drives staples onto the edge portions of the sheet bundle.

When the stapling operation is completed, the solenoid 421c is turned OFF.
FF. Chucks that were closed until now because of this: Top 4
21) L, Chuck: The bottom 421m will be open.

The movement at this time returns from the state shown in FIG. 37 to the states shown in FIGS. 32 and 34 due to the force of the spring 421f.

Also, the pin 421v that was caught on the return plate 422z
34, the return plate 422Z is pulled by the spring 422n and returns from the state shown in FIG. 38 to the state shown in FIG. 34.
At that time, it works to return the paper stack to its original position.

Fig. 43 shows the return plate 422z and the return plate bracket 422x.
and the relationship with the spring 422n. Return plate 42
The tip of the paper 2z is designed to be wider than the space between the pins to ensure that the paper is returned onto the pins 300. Further, a portion of the return plate bracket 422X protrudes obliquely toward the pin 300. This is shown in Figure 44,
When returning weak paper or curly paper P, etc., there is a risk that it will be pushed by the return plate 4222 and escape upwards, so this guide plate is provided as a countermeasure for this problem. In this way, the stapled paper P is reliably returned onto the pins.

After that, the stapler 401 and paper pulling device 402
is transported downward to the next pin, where a stapling operation similar to that described above is performed again.

As shown in FIG. 39, a pin fence 316 for aligning the stack of recording sheets is provided at the edge portion of each pin 300 facing the stapler 401 side.
It is provided so that it starts up from 0. The lower edge portion of this pin fence 316 is rotatably attached to a support shaft 425 provided along the lower surface side of the pin 300, so that the pin fence 316 is tilted to the open position shown in FIG. It has become so.

Both end portions of the support shaft 425 are rotatably supported by bearing pieces 423b formed downward at both end edge portions of the pin 3000. Further, a coiled spring 426 is attached to the support shaft 425. Both winding end portions of the winding spring 426 are held in contact with the lower surface side of the pin 300 and the back side of the pin fence 316, respectively, and the rotational force of the winding spring 426 causes the pin fence 316 to
receives a biasing force in the rising direction.

Generally, the pin fence 316 is opened according to the vertical movement of the stapler 401 via the fence tilting member. This fence tilting member includes a fence movable plate 427 attached to the support shaft 425 side, and a fence release plate 42 provided to the stapler 401 side.
It consists of 8.

The fence movable plate 427 is inserted into a fan-shaped hole opened in one piece 424a of the pin fence 316.
27, and when the fence movable plate 427 rotates downward, a piece 316a of the pin fence 316
The lower part of the fan-shaped hole contacts the pin fence 3.
16 is adapted to tilt according to a fence movable plate 427. Further, when the fence movable plate 427 rotates upward, it rotates away from the pin fence 316 side without contacting it, so the fence movable plate 427 rotates freely. .

Further, the rollers 428a of the fence release plate 428 extend to a position where they come into contact with the fence movable plate 427, and when the stapler 401 moves up and down, the rollers 428a contact the fence movable plate 427 and rotate the fence movable plate 427. It has become.

In the apparatus in this embodiment, when a sorting operation is first performed, the pin fence 316 is maintained in the upright position by the rotational force of the coiled spring 426, as shown in FIG. As a result, the edge portion of the paper discharged onto the pin 300 comes into contact with the pin fence 316, and alignment is performed. When this sorting operation is completed, the stapler 401 mentioned above begins to descend,
Roller 42 of fence release plate 428 on stapler 401 side
8a contacts the fence movable plate 427 on the pin 300 side. Then, the fence movable plate 427 is rotated to the lower position as shown in FIG.

As the fence movable plate 427 rotates, the pin fence 316 tilts against the rotational force of the coiled spring 426, thereby releasing the pin 300. At this time, the pin fence 316 and the fence movable plate 427 are pushed down to a position below the plane position A of the pin 300, which is indicated by the dashed line in FIG. In this state, the stapling operation as described in the above embodiment is performed.

The stapler 401 moves downward toward the next pin at the same time as the stapling operation is completed and the paper stack returns to the original position of the pin 300, or while the paper returns. When the fence release plate 428 is separated from the fence movable plate 427 by the downward movement of the stapler 401, the pin fence 316 rises due to the rotational force of the coiled spring 426 and returns to its original position. Such opening and stapling operations of the pins 300 are performed by the sorted pins 30.
This is done for all 0's.

Once all the stacks of recording paper have been stapled,
The stapler 401 rises and returns to the highest home position. The home position is placed at the top1
It is located further above the pin 300 in the row. When the stapler 401 returns, the fence release plate 428 on the stapler 401 side contacts the fence movable plate 427 from below, but in this case, the fence movable plate 427
As shown in FIG. 41, the pin fence 316 escapes and rotates upward in a idling state, so the pin fence 316 is not rotated at all. When the fence release plate 428 of the stapler 401 is separated from the fence movable plate 427 due to the upward movement of the stapler 401, the fence movable plate 427 returns to its original position as shown in FIG. 39 due to its own weight.

In the embodiment shown in FIG. 42, an elastic body 429 that receives a fence movable plate 427 is installed on the pin fence 316 side. In such an embodiment, when the stapler 401 returns, when the fence movable plate 427 rotates upward in an idling state, the fence movable plate 427 comes into contact with and is received by the elastic body 429, and its Due to the bending repulsive force of the elastic body 429, the fence movable plate 4
27 returns to its original position.

Next, regarding replacing the staple cartridge of the stapler 401.
This will be explained based on FIGS. 46 to 50.

In this embodiment, the main body of the copying machine (not shown) has a paper reversing device, and the paper is ejected from the first sheet of the document stack with the image surface facing downward, so the stapler 401 is installed in the opposite direction.

FIG. 46 shows the configuration of the stapler 401. In the figure, by pushing the release lever 480G upward, the release lever 480C moves clockwise around the shaft 480F, and as the shaft 480B slides in the groove, the release claw 480
B moves counterclockwise around axis 480D, and axis 481E
(Figure 47).

Further, as shown in FIG. 48, since the shaft 481E is opened, the stapler section 481 can be moved clockwise around the shaft 483, and the release claw 480B is returned to its initial state by the spring 480G. When the stapler section 481 is moved clockwise, the shaft 482A slides in the groove and is locked in the groove, the stapler section 481 is also locked. In this state, the stapler section 481 is stopped at an angle rather than vertically, and almost protrudes from the exterior of the sorter main body, allowing the user to easily replace the staple cartridge 481C. After replacing the needle cartridge 481C, as shown in FIG. 49, by pushing the release lever 4800 upward, the release lever 480C moves clockwise around the shaft 480F, and the lock of the shaft 482A is released. When the shaft 482A is unlocked, the stapler section 481 moves to the shaft 483.
It can be moved counterclockwise around the release lever 4.
80C is returned to the initial state by spring 480G.

As shown in FIG. 50, the stapler section 48 moved counterclockwise has its shaft 481E hitting the release claw 48OB,
The force of the shaft 4.81E opens the release claw 480B, and after the shaft 481E has passed, the release claw 480B opens the spring 4.
80G, the stapler section 481 is locked. By such an operation, the staple cartridge of the stapler can be easily replaced.

Among the signals exchanged with the copying machine, the signals sent from the copying machine to the sorter and stapler include a sorter start signal, a copying machine ejection signal, a mode signal, a size signal, a staple start signal, a staple end signal, and a service signal. Call reset signal (S, C.

The signals sent from the sorter and stapler to the copier include an eject signal, each door cover open signal, a JAM signal, an over-pin signal, an error signal, a no-staple signal, a staple end signal, a staple permission signal, There are sort permission signals, etc.

The operation and control of the embodiment of the present invention will be described below with reference to flowcharts. The overall operation flow is shown in Figure 54 (a).
It is shown in FIG. 54(b).

First, an operation mode signal sent from the copying machine is received (step 54-1), and a set number signal sent from the copying machine is received (step 54-2).

After copying starts, the copying machine sends a sorter start signal (step 5f-3), and upon reception of this signal, the drive motor 2
00 is ONL (step 54-4), and the sort mode is entered (step 54-5.546). When the sorter start signal is not sent, it is in a wait state. The operation in the sorting mode is as shown in FIG. (Step 54-10).The size signal is received and it is determined whether swinging is possible or not (Step 54-1).
), if swinging is possible, the receiver moves the swinging device to the position corresponding to the received size signal (step 54-12).

Below, each of the above operations is shown in FIG. 56(a) and FIG.
This will be explained according to the subroutine shown in .

Figure 56 (The preset operation of the al size counter is
If the size signal has been received (step 56-1), the size position data is set in the size counter based on the received size signal (step 562), the swing unit is instructed to move (step 56-3), and the process returns (step 56-1). RET
) (step 56-4). If the size signal is not received, RET is performed as is.

In the moving operation of the swinging device (unit) shown in FIG. 56 (bl), if the swinging unit does not move (step 56-5), the RET is performed as is (step 56-6).

(step 56-8), and it is determined whether the size detection sensor 531 has changed from OFF to ON.

If the size detection sensor 531 has not changed from OFF to ON (steps 56 to 9), perform RET as is (

Next, returning to the flowchart of FIG. 54(b), when a copy (sheet) is ejected from the copying machine, an ejection signal is sent (step 54-13). The electromagnetic clutch (CL) 633 is turned on at the timing of receiving this paper discharge signal (step 54-14). Next, a copy is brought in from the copier,
Inlet sensor 619 is ONL (Step 7 54-15>,
Switching 5OL at the timing of turning on this population sensor 619
634 is ONL (step 54-16), and the paper is ready to be discharged to the sorting pin. A little later than the ON timing of this population sensor 619, the ejection pin deflection 5OL635~
Of the 654, the ejection pin is ONL, and the copy is guided to the pin (step 54-17). After the copy is ejected and placed on the pin after an appropriate amount of time (e.g. 300m)
After 5 ec, in steps 54 to 18), the swing motor 520 is turned on and the swing plate is moved to perform alignment (step 5419). In addition, the timing to move the rocking plate is as follows.
The trailing edge of the copy is detected and used as a reference.

Next, this swinging operation will be explained with reference to FIG. 57 showing a subroutine.

When a copy is ejected, the upper entry sensor 629 or lower entry sensor 628, which detects paper ejection to the pin, is first turned on. Next, when the discharge is completed, the upper entry sensor 629 or the lower entry sensor 628 changes from ON to OFF (step 57-1). The point where this change from ON to OFF is at the trailing edge of the paper. Entry sensor upper 629 or lower 628 ON to OFF
At the timing of the change to F, a timer provided in the CPU 600 is started (step 57-2). Next, the value of the timer is monitored, and when it is determined that 300m5EC has elapsed in this embodiment since the timer started (step 57).
-3), if the timer is stopped (step 57-4) and the swing is possible (step 57-5), the swing motor 520 is turned on to start swinging (step 57-6).
). After that, the above operation is performed every time a copy is ejected, and the alignment is performed.

However, after the number of copies stacked on the pin exceeds the number of sheets that can be stapled (30 sheets in this example), the swinging unit that interferes with sorting is stopped, the swinging unit is evacuated to the home position, and the paper is ejected. Prohibits stapling of paper copies.

This operation will be explained below according to the subroutine shown in FIG.

The number of copies stacked on the pin is detected (step 58-2) by counting when the copies are discharged to the leading pin (step 5B-1).

When it is determined that the discharge count value of the leading pin exceeds the number of sheets that can be stapled (step 58-3), the swinging operation is stopped (step 5B-4), and the swinging unit is retracted to the home position (step 58-3). 5) From now on, alignment is not performed on the ejected copies. At the same time, stapling is also prohibited for previously ejected copies (step 586).

Next, the stapling operation will be explained. Figure 54(b)
, when a stapling start signal is received (step 54-20), a stapling operation is entered (step 54-20).
-21), step 54 when the stapling operation is completed.
-22), the staple moving unit moves to the home position (step 54-'23). The stapling operation is performed according to software instructions (step 54-24).
).

Therefore, as can be seen from the flowchart shown in FIG. This allows for efficient paper processing.

There are two types of stapling operation modes: a "manual stapling operation mode" in which stapling is performed after sorting is completed, and a "manual stapling operation mode" in which stapling is automatically started after sorting to one pin is completed while the sorting operation continues. There is an "auto staple operation mode".

First, the manual stapling operation will be explained based on FIG. 55(a) showing a subroutine.

After the sorting is completed, if a copy is placed on the pin, the copying machine transmits a stapling start signal, and upon receiving this signal, starts operation.

First, the stapler 401 at the home position is moved to the first pin to be stapled. Stapler 401
After moving to the first pin, the operation proceeds based on the value of the stapling operation sequence counter described in fal in FIG.

When the stapler 401 finishes moving to the first pin, the value of the staple sequence counter is set from 0 to 1 (step 55-1). When the value of the staple sequence counter is 1, the chuck motor 422f is ONL,
The chuck unit is advanced (step 55-2).

When the front chuck sensor 422j that detects the end of the forward movement of the chuck unit is turned on (steps 55-3), the forward movement of the chuck unit is ended (step 55-4), and the staple sequence counter is set to 2 (step 3).
5-5), proceed to the next operation.

When the value of the staple sequence counter is 2, step 55-6), the chuck 5QL421C is turned on, step 55-7), the staple sequence counter 3 is set, step 55-8), and the operation proceeds to the next step.

When the value of the staple sequence counter is 3 (step 55-9), hold that state for 0.2 seconds, and after 0.2 seconds have passed (step 55-10), set the staple sequence counter to 4.Step 55 -1)), proceed to the next operation. Staple sequence counter value is 4
When (step 55-12) -, chuck motor 4
22f is turned on and the chuck unit is moved to the home position (step 55-13). A post-chuck sensor 422 that detects the end of home movement of the chuck unit
k is ONL (step 55-14), the home movement of the chunk unit is completed (step 55I5), and the staple sequence counter is set to 5 (step 55-15).
16), proceed to the next operation.

When the value of the staple sequence counter is 5 (step 55-17), check the output of the paper presence/absence sensor 623 (step 55-18), and when the staple is present, perform the stapling operation (step 55-19) . Step 7 55-20) to detect the completion of the binding operation, and set staple sequence counter 6 (Step 55-12) L
, proceed to the next operation. When the output of the paper presence/absence sensor 623 is a paper error, the stapling operation is not performed and the operation proceeds to the next step.

When the value of the staple sequence counter is 6 (step 55-22), the chuck SQL42lc is set to 0FFL.
(Step 55-23), the stapled pin counter is counted up, and the swing motor is moved to bring the stapled pins together (Step 55-24). Then, the value in the staple reservation pin memory indicating the total number of pins to be stapled is compared with the value in the stapled counter, and if the values match (step 55-25), O is set in the staple sequence counter and the stapler operation ends. Step 55-26), then turn the vertical movement motor 409 ONL,
Move the stapler unit to the home position (
Steps 55-27).

Note that the method for calculating the value of the staple reservation pin memory and the staple paper stacking will be described later. When the value of the stapled counter is smaller than the value of the staple reservation pin memory, the staple sequence counter hair is set (step 55-28) and the operation proceeds to the next step.

When the value of the staple sequence counter is 7, the state is held for 0.3 seconds, and after 0.3 seconds have passed (step 55-
30) Set the counter to O (step 55-31) and instruct the start of stapler movement to the next pin shown in subroutine Fig. 55fbl (step 55-32).
.

The operation of the subroutine shown in FIG. 55 (bl) will be explained below.

First, the start of stapler movement is determined, and when the stapler movement start is instructed (steps 55-50), the vertical movement motor 409 is turned on and at the same time a timer is started (
Steps 55-51).

When it is determined that the time has expired (steps 55-52), the stapling sequence counter is set to 1 and the stapling operation for the next pin is started (steps 55-53). 0N10FF of vertical position sensor 415
(steps 55-54), and when the vertical movement motor 409 is turned on, the vertical movement motor 409 is turned off (steps 55-55).
), end the pin-to-pin movement.

In this embodiment, the next pin stapler finishes moving approximately 1
00m5. By starting the stapling operation for the next pin before EC, time is reduced.

The above operation is repeated until the value of the staple pin reservation counter and the value of the stapled completed counter match.

Next, the auto stapling operation will be explained based on FIG. 55(a). During sorting, a stapling start signal is sent when the copier ejects the first copy of the final original, and after receiving this signal, the first copy of the final original is ejected from the machine, and then the first copy of the final original is ejected from the machine. The stapling operation starts when the copy is shaken. First, the stapler 401 at the home position is moved to the first pin to be stapled. After the stapler 401 moves to the leading pin, the operation proceeds based on the value of the stapling operation sequence counter described in the subroutine FIG. 55(a). When the stapler 401 finishes moving to the first pin, the value of the staple sequence counter is set from O to 1 (step 55-1). When the value of the staple sequence counter is 1, the chuck motor 422 is turned ON and the chuck unit is moved forward (
Step 55-2). When the chuck front sensor 422j that detects the end of the chuck unit's forward movement is turned on (step 55-3), the chuck unit's forward movement is ended (step 55-4), the staple pin pre-counter is set to 2, and the operation proceeds to the next step. . When the value of the staple sequence counter is 2 (step 55-6), the chuck 5
Turn on the QL421C (step 55-7), set the staple sequence counter to 3 (step 55-8)
), proceed to the next operation.

When the value of the staple sequence counter is 3 (step 55-9), the state is held for 0.2 seconds, and after 0.2 seconds have elapsed (step 55-10), the staple sequence counter is set to 4.Step 55- 1)), proceed to the next operation.

When the value of the staple sequence counter is 4 (step 55-12), the chuck motor 422f is turned ONL,
The chuck unit is moved to the home position (step 55-13). The post-chuck sensor 422k that detects the end of the home movement of the chuck unit is ONL (step 55-14), the home movement of the chuck unit is completed (step 7"55-15), and the staple sequence counter is set to 5 (step 55-16). ), proceed to the next operation.

When the value of the staple sequence counter is 5 (step 55-17), the output of the paper presence/absence sensor 623 is checked (step 55-18), and when the stapling is completed, a stapling operation is performed (step 5519). When the end of the stapling operation is detected (step 5520), 6 cents is added to the staple sequence counter (step 55-12), and the operation proceeds to the next step. When the output of the paper presence/absence sensor 623 indicates that there is no paper, the stapling operation is not performed and the operation proceeds to the next step.

When the value of the staple sequence counter is 6 (step 55-22), the chuck 5OL421C is set to 0FFL.
(Step 55-23), the stapled pin counter is counted up, and the swing motor is moved to bring the stapled pins together (Step 55-24). Then, the value of the staple pin reservation memory indicating the total number of pins to be stapled is compared with the value of the stapled counter, and if the values match (step 55-25), O is set in the staple sequence counter and the stapler operation is terminated. Step 55-26), then move the vertical movement motor 409 ONL and the stapler device 400 to the home position (
Steps 55-27).

Note that the method for calculating the value of the staple reservation pin memory and the staple paper stacking will be described later.

When the value of the stapled counter is smaller than the value of the staple pin reservation memory, it indicates up to which pin the oscillation has been applied. The swung pin memory and the stapled counter are compared (step 55-33), and if the value of the swung pin memory is large, the staple sequence counter hair is set and the operation proceeds to the next step. When the values of the oscillated pin memory are small or equal (step 55-33)
, the stapler maintains its state and cancels the rocking prohibition process (steps 55-38), and encourages rocking. In this way, it is determined which of the aligning means (oscillating motor) and stapling means (stapling device 400) should be prioritized.

Also, in the determined size (step 5535), t
If the value of the i-pinned pin memory is 2 or more than the value of the stapled pin memory, the staple sequence counter hair is set and the operation proceeds to the next step (step 55-3).
6). If the value is 1 or less, the stapler maintains its state, cancels the rocking prohibition process (step 5537), and urges the ti motion. Note that the rocking prohibition process and the calculation of the rocked pin memory will be described later. In this way, it is possible to perform the swinging operation at least twice on the target paper set before stapling.

When oscillation is performed and the value of the moved pin memory becomes larger than the value of the stapled pin memory, or when it becomes 2 or more for the specified size, 7 is sent to the staple sequence counter. Step 55-
28), proceed to the next operation. When the value of the staple sequence counter is 70, the state is held for 0.3 seconds and 0.
After 3 seconds have elapsed, the previously described subroutine shown in FIG.
Instructs l to start moving the stapler to the next pin.

Calculation of staple reservation pins will be explained according to the subroutine shown in FIG. 59. In order to calculate this, in this embodiment, during the sort mode operation, a previous original copy ejection pin number memory that stores the number of pins to which the copy paper of the original has been ejected for each original, and a maximum number of pins during one sorting operation. It has a pre-ejection maximum pin number memory that stores how many pins have been ejected and a staple pin number reservation memory that instructs how many pins to staple.
The contents of memory are being moved.

The copying operation is started in the sort mode (step 59-1), and at the timing when the copy paper is ejected from the first pin of the sorter (step 59-2), the previous original copy ejection pin number memory and the previous ejection maximum pin number memory are stored. The contents are compared (step 59-3), and if the value of the previous original copy ejection pin number memory is larger than the value of the previous original copy ejection pin number memory, the value of the previous original copy ejection pin number memory is changed to the value of the previous original copy ejection pin number memory. 1 is substituted into the memory (step 5974), and 1 is substituted into the previous original copy ejection pin number memory (step 59-5).

The value in the previous original copy ejection pin number memory increases as 2, 3, etc. when a copy is ejected to the 2nd pin, 3rd pin, and so on. In the staple pin number reservation memory, the contents of the current ejection pin number and the previous ejection maximum pin number memory are always compared (step 59-6), and the contents of the smaller memory of I& are assigned to the staple pin number reservation memory. (Step 59-7). Since the contents of the staple pin number reservation memory change depending on the situation, it can be handled even when a stapling operation is performed while copying is being ejected, as in the auto stapling mode.

This will be explained specifically.

As an example, it is assumed that stapling is reserved for the 10th pin for the first copy of the original, the 5th pin for the second copy, and the 7th pin for the third copy.

First, the first copy of the original is ejected to pin 1 (first pin). At this time, the maximum number of front ejection pins M and the number of previous original copy ejection pins are both O, so step 59-
3 is N, and l is entered in the number of previous original copy ejection pins (step 59-5). Then step 59-6
The current ejection pin number is compared with the value stored in the previous ejection maximum pin number memory. When the first copy of the original is ejected to pin 10, the current number of eject pins is 1.
0, and the previous ejection pin number M is O, so the current ejection pin number is larger, and the judgment at step 59-6 is N, and O is entered in the staple pin number reservation memory.

Next, the second copy of the original is ejected to pin 1 (first pin). At this time, the maximum number of pre-ejection pins M is O1, and the number of pre-original copy ejection pins (counted and knobped in other routines) is 10, so the determination in step 59-3 is Y.
Therefore, 10 is included in the maximum number of pre-ejection pins M. Then, when the second copy of the original has been ejected up to 5 pins, the current ejecting pin number is 5, the previous ejecting maximum pin number M is 10, and the judgment in step 59-6 is Y, and the staple pin number reservation memory contains 5.

Finally, the third copy of the original is ejected to pin 1 (first pin). At this time, the maximum number of front ejection pins M is 10, and the number of previous original copy ejection pins is 5, so step 59-3
The determination is N, and the maximum number of pre-ejection pins M remains lO. Then, when the third copy of the original has been ejected up to pin 7, the current number of ejected pins is 7 and the maximum number of previously ejected pins is 10, and the judgment in step 59-6 is Y.
The staple pin number reservation memory finally contains 7,
The copy corresponding to the final original is stapled to the ejected pin.

By doing so, the pin that activates the binding means 400 can be the pin from which the paper corresponding to the final manuscript is ejected, and it is possible to bind a set of papers with all the pages as possible.

However, if you just want to achieve the above, you don't need to set up such a complicated procedure (or you can just look at the number of pins currently being ejected and put that value in the staple pin number reservation memory). However, the above procedure is set for the purpose described below.

This will be explained below according to the following example.

In this example, it is assumed that stapling is reserved for pin 7 for the first copy of the original, pin 5 for the second copy, and pin 10 for the third copy.

First, the first original is ejected to the copy pin (leading pin). At this time, the maximum number of front ejection pins M and the number of previous original copy ejection pins are both 0, so step 59-3
The determination is N, and 1 is entered in the number of previous original copy ejection pins (step 595). Here, the inclusion of ■ means that the number of previous document copy ejection pins is reset for each document. When the process of step 59-5 is completed, the current number of pins for ejection is compared with the previous maximum number of ejected pins memory in step 59-6. When the first copy of the original has been ejected up to 7 pins, the current number of ejected pins is 7, the previous maximum ejected pin number M is 0, and the determination at step 59-6 is N. As a result, O is entered in the staple pin number reservation memory.

In this way, when the first copy of the original is ejected to pin 7, the second copy of the original is ejected, but when the second copy of the original is ejected to pin 5, , the currently ejected number of pins is 5, and the previous ejected maximum pin number M is 7, the determination is Y, and 5 is entered in the staple pin reservation memory at step 59-7.

Subsequently, the third copy of the original is ejected to pin 1 (first pin). At this time, the number M of front ejection pins is 7, and the number of ejected copies of the previous original is 5, so the determination in step 59-3 is N.
Therefore, the maximum number of front ejection pins M remains 7. Then, when the third copy of the original is ejected up to pin 10, the current number of ejected pins is 10, and the maximum number of pins ejected before is M.
is 7, and the determination at step 59-6 is N. As a result, the staple pin number reservation memory finally contains 7
will be inserted and stapled up to pin 7.

This means that while the final original copy contains up to 10 pins, only up to 7 pins are stapled. The reason for this is that pins 8, 9, and 10 ultimately contain only one copy, so that one copy is not stapled.

Note that when there is only one original, the content of the staple pin reservation memory is O, and stapling of one copy is naturally prohibited.

In this way, the binding means 40 is attached to the pin on which the number of sheets of paper on which the sheet corresponding to the final original is ejected is only one.
By disabling 0, unnecessary binding operations are prevented even when the number of copies of the final original is changed.

The stapling priority swing prohibition process will be explained according to the subroutine shown in FIG. 60.

First, check whether the stapling operation is in progress (step 6O-1); if YES, check whether the chuck SQL (solenoid) is ON (step 6O-2); if YES, after the chuck has moved to the home position, Time is 0. Please check if it is 3SEC or more (step 6O-3), if no,
Swinging is permitted (step 6O-4). If check S
If QL is not ON, rocking is prohibited (step 6O-5). Furthermore, if the time after the chuck finishes moving to the home position is equal to or greater than 3 sEc, the swinging is prohibited and RET is performed. Further, if the stapling operation is not in progress, swinging is unconditionally permitted and RET is performed.

Next, calculation of the oscillated pin memory will be explained according to the subroutine shown in FIG. 61.

First, it is checked in step 6l-1) whether or not the rocking has been performed once. If the rocking has not been performed even once, RET is performed directly. Further, if one swing operation has been performed, the value of the number of paper ejection pins is entered in the swing completed pin memory (step 612), and the process is RET. What is the number of paper ejection pins?
This shows how many pins are currently being ejected, and the swung pin memory shows how many pins are currently being swung.

The staple paper collection will be explained according to the subroutine shown in FIG. 62.

After stapling is completed (step 62-1), when the chuck solenoid 421C is turned off, the paper return bracket l-
422z, the stapled copy (paper) slides on the pin and is pushed back into the swing plate rotation area, completing the stapling l operation. At this time, FIG. 55 (al
The staple 1 operation end flag is set in the subroutine shown in FIG. The completion of the staple l operation is determined based on the content of this staple l operation end flag. staple l
After determining that the operation is completed, the chuck 5QL421c moves to the next pin and performs the stapling 1 operation again.
When it is determined that it is N (step 62-2), swinging is started (step 623). Then, the stapled paper on the front pin is moved to a predetermined position. By this staple paper shifting operation, the stapled paper on the pin is moved to a predetermined position so as not to adversely affect the alignment of the paper discharged from the next pin onwards.

In addition to the functions and operations described above, this embodiment has several functions and operations shown below.

Each will be explained based on the flow of the subroutine. First of all, two-system stapling processing means that the sorter pins are
After sorting and stapling the L system, it is possible to perform sorting and stapling on the other system without releasing the pins on the first system, and the copy size of the upper and lower systems Mode A, where the condition is that the above and
There is a mode B, which is a lower system and requires that the copy size of the system to be processed later is larger than that of the system that is preprocessed, and can be switched according to the user.

Mode A-2 system stapling processing will be explained based on the subroutine flow of FIG. 63.

Here, sorting using the other system after processing by one system is called dual sort. When attempting to perform dual sort, if dual sort is not possible (step 6)
3-1), disable sort mode step 63-2)
,Warning. If dual sorting is possible, the paper size is detected, and if the paper size at the previous sort and the paper size to be dual sorted are the same size, the operation continues as is. If the paper size during the previous sort and the paper size to be dual sorted are different sizes (step 63-3), the swinging section is retracted (step 63-4).
, prohibit stapling (step 63-5),
Continue.

Next, regarding mode B-2 system stapling processing, the 64th section
The explanation will be based on the subroutine flow shown in the figure.

When attempting to perform dual sorting, if dual sorting is not possible (step 641), sort mode is prohibited and a warning is issued (step 642). If dual sorting is possible, the paper size is detected, and if the paper size to be dual sorted is larger than the paper size at the previous sort, or if the paper sizes are the same size,
Continue operation. From the paper size at the time of previous sorting,
If the paper size to be dual sorted is smaller (step 64-3), the swinging section is retracted (step 64-4), and stapling is prohibited.
5), the operation is mVt.

Although the above process describes prohibition of stapling by the stapling means 401, it is also possible to cancel the operation of the aligning means 502 instead of the stapling means 401 using a similar process.

No. 65 regarding door opening during stapling process
The explanation will be based on the subroutine flow shown in the figure.

During stapling operation (step 65-1), if the stapler door, sorter door, and sorter top cover are all closed, the operation continues M1, and if the stapler door is opened (step 652), the stapling sequence Set the counter to O, step 65-3), and turn off the entire load.
F (step 65-4).

The stapler door is closed during the stapling operation.
If either the sorter door or sorter top cover is opened (
Set to state 1. The process of step 655) will be explained below.

If the chuck unit is moving forward in state B1 (step 7
step 65-6), set the staple sequence counter to O, step 65-7), and turn off the chuck motor (
Step 65-8).

After the chuck unit moves forward in state B1, and within 0.2 seconds after the chuck 5QL421C is turned on (step 65-9), the staple sequence counter is set to O.
Step 65-10), Chuck 5OL421C
(step 65-1)).

The processing after the chuck unit moves forward in state 1 and after 0.2 seconds after chuck SQL is turned on (state B2) will be described below.

If the chuck unit is retracting in state 2 (state 7
"65-12), the staple sequence counter is set to 4, and the operation continues at step 65-13).

If the chuck unit has moved backward in state 2 and the stapler is in the closing operation (step 65-14), the staple sequence counter is set to 5 (step 65-1).
5) Continue operation.

If the chuck unit has retreated in state B2 and the stapler closing operation has been completed, the staple sequence counter is set to O (step 653), and the entire load is turned off.
(step 654).

In addition, if the vertical movement motor 409 is operating in the shaped part 1 (
Step 65-16), the staple sequence counter is set to 0 and the entire load is turned off.

Regarding variable descending speed for staple start pins,
This will be explained based on the subroutine flow shown in FIG. 66.

If the currently stopped position is other than the home position (step 66-1), set the motor rotation speed to high speed (step 66-2) and turn on the vertical movement motor 409.
L is lowered (step 663).

If the current stopped position is the home position,
The descending speed is varied depending on the number of pins to be stopped next.

That is, when the pin to be stopped is the first pin (step 66-4), the rotation speed is set to high speed in step 66.
-2), turn on the vertical movement motor 409 (step 6).
6-3). If the pin to be stopped is the second or higher pin (step 66-4), the rotation speed is set to a low speed in step 66.
5) Turn on the vertical movement motor 409 (step 66
-3).

Next, the function of slowing up and slowing down vertical movement will be explained. This function gradually increases the movement speed when starting the vertical movement, moves at a constant speed when it reaches the set value, and when the vertical movement stops, gradually decreases the movement speed from before the pin position to stop. When the value is reached, it is moved at a constant speed and stopped at the stop pin position.

This will be explained based on the subroutine flow shown in FIG. 67. 1m
In the subroutine that is called every 5EC, after the vertical movement motor 409 is turned on (step 67-1), if the slow-up operation has not been completed (step 67-2)
, the slow-up counter increases by one for each subroutine call (step 67-3). Speed data is set in the CTC 604 from among the speed data group in the ROM 601, which is set to gradually increase the speed based on the value of the slow-up counter (step 67-4). This CTC 604 generates a frequency based on the set speed data and sends it to the phase signal generation section 614 in FIG. 53. A phase signal is sent from the phase signal generation unit 614 to the constant current dry harrow 15, and the vertical movement motor 409 operates at a rotation speed corresponding to the speed data.

When the slow-up counter reaches a certain set value (step 67-6), the slow-up is terminated (step 67-13), and the vertical movement motor 409 then operates at a constant rotation speed.

After a certain period of time, the slowdown operation will start. Stenoor '6
7-7), the slowdown counter is incremented by one for each subroutine call (step 67-8). The ROM 6 is set to gradually decrease its speed based on the value of the slowdown counter (step 67-9).
From the speed data group in 01, select the speed data as C.
Set to TC604 (step 67-10). This CTC 604 generates a frequency based on the set speed data and sends it to the phase signal generation section 614.

The phase signal from the phase signal generation unit 614 is sent to the constant current driver 615.
The vertical movement motor 409 operates at a rotation speed corresponding to the speed data.

When the slowdown counter reaches a certain set value (step 67-1)), the slowdown is terminated (steps 67, -12), and the vertical movement motor 409 then operates at a constant rotation speed. When the stapler reaches the pin to be stopped, the vertical movement motor 409 is turned off and stopped, and the slow-up counter and slow-down counter are cleared (step 67-14).

The vertical movement abnormality mitigation routine will be explained based on the subroutine flow shown in FIG. 68.

When an abnormality in the vertical movement motor 409 is detected, if the abnormality detection count number (step 68-1) is the second time, (
Step 68-2) Transmit an abnormality signal to clear the count.Step 68-6), resulting in a serviceman call (
Step 68-7).

However, when an abnormality is detected for the first time (step 68-2)
, if the vertical movement motor 409 is rising (step 6
8-3) and restart the motor 409 (step 68-
4) Continue the operation, and if it is descending, send a jam signal (step 685) and move on to the next process.

Specifically, the stapling means 401 or the aligning means 50
If some abnormality occurs in step 2, for example, a first interruption signal that simply interrupts paper ejection from the copying machine main body;
a second interruption signal that interrupts paper ejection from the copying machine main body and requests an abnormality reset signal; transmits the first interruption signal when the first abnormality is detected;
It is conceivable to transmit an interruption signal when an abnormality is detected for the second time or later. It is also conceivable that the first interruption signal is a jam signal and the second interruption signal is an abnormality signal. It should be noted that the abnormality is not limited to that in the vertical movement motor 409, but also includes an abnormal state in each part constituting the stapling means 401 or the aligning means 502.

Flowcharts from FIG. 69 to FIG. 79 show processing operations corresponding to various abnormal states. These processing procedures will be explained below.

FIG. 69 is a flowchart showing a processing procedure for detecting a size movement or more.

In this process, first, it is determined whether the size movement motor is ON (step 69-1), and if it is ON, it is further determined whether the size movement abnormality detection timer is operating (step 692). If the size movement abnormality detection timer is not in operation, the size movement abnormality detection timer is started (step 69-3), and it is determined whether the size detection sensor has changed from OFF to ON (step 69-4). In addition, if it is determined in step 69-2 that the size movement abnormality detection timer is operating, step 69-3 is not performed and the size movement abnormality detection timer is determined to be in operation.
-Perform process 4.

In step 69-4, the size detection sensor is turned from OFF to ON.
If it is determined that the size change has changed, the size movement abnormality detection timer is reset and restarted in step 69.
-5), it is determined whether the size movement has reached the stop position (step 696). If the size movement abnormality detection timer has not reached the stop position in this judgment, it is determined whether the size movement abnormality detection timer has exceeded (Step 69-7). If it has exceeded, an abnormality signal is sent to the copying machine (Step 698) and the abnormality processing is carried out. The subroutine is executed (step 69-9). Furthermore, after executing the abnormality processing subroutine of step 69-9, the size movement motor is set to 0FFL (step 69-9).
10), reset the size movement abnormality detection timer and stop the timer (step 69-1)) perform RET.

On the other hand, if it is determined in step 69-6 that the size movement stop position has been reached, the size movement motor is
FFL (step 69-12), reset the size movement abnormality detection timer and stop the timer (step 69-1)
3) RET. Further, if it is determined in step 69-7 that the size movement abnormality detection timer has not exceeded, the size movement abnormality detection timer is counted up (step 69-14), and the process returns to step 69-4, and from the same step Repeat the process. Note that step 69-
If it is determined in step 1 that the size movement motor is not turned on, the process directly returns RET.
