Then, the paper S that finishes imaging and discharge from paper discharge section 208 sends paper processing device 400 to, and in this paper processing device 400, handled according to preassigned mode of operation, for example selection or bookbinding, and be stacked on the suitable dish (stacking dish 421 or stacking dish 422).

To introduce paper processing device 400 below.

As shown in fig. 1, paper processing device 400 is packed into and is formed in the space S P of imaging device main body 500A sidepiece, from main body 500A, do not protrude, and this paper processing device 400 also provides the bookbinding function except the selection function that is used to choose paper, be used for carrying out stapling operation by for example attachment means unit 420 shown in Fig. 4.As shown in Figure 2, it provides: process disk 410 is used for handling the paper S that discharges continuously from imaging device main body 500A; Stacking dish (bottom storage tank) 421 and stacking dish (top storage tank) 422 are used for finally being stacked in the stacks of sheets of handling on the process disk 410; And, with its formation be controlled to like this, that is, on process disk 410, form the stacking (the paper number is identical with the original paper number) of a plurality of paper, and with each stacks of sheets discharge be stacked on stacking dish (bottom storage tank) 421 or the stacking dish (top storage tank) 422.

This structure and control make a plurality of (being two in the present embodiment), and stacking dish 421,422 can independently raise and reduce, thereby a kind of novel structure is provided.Also have, this structure and the control stacking of not only can in the output function of duplicating working, on stacking dish 421,422, classifying, and can be in output services away from imaging device (for example in print job or the fax work) stacking of classifying, thereby satisfy customer requirement.

Reader partial sum autofile feeder (ADF) is arranged on the imaging device main body in the embodiment shown in fig. 1, but when not having these members, paper processing device 400 is positioned on the imaging device (or printer section) naturally.Like this, nature can be saved the space.

To introduce the structure of paper processing device 400 below.

With reference to figure 2, paper receiving unit 401 receives the paper S that discharges from imaging device main body 500A, and the paper S that receives by paper receiving unit 401 after detecting by inlet sensor 403 by transfer roller 405 with depart from (offset) roller 407 and be transmitted, and be sent to as shown in Figure 3 on the process disk 410, this process disk 410 constitutes the bunching device of paper treated, and is arranged in the paper process part 400B that is used for paper process.The paper S that is stacked in like this on the process disk 410 is detected by stacks of sheets discharge sensor 415.

Departing from roller 407 is made of cylindrical part, and as sheet feeding, its outer peripheral portion is made of the elastomeric element with rubber-like elasticity (for example rubber or foam components), and this departs from roller 407 by departing from 406 supportings of roller retainer, so that can be around off-axis 511 (shown in Fig. 4) perpendicular movement.

Departing from roller retainer 406 makes to the off-axis 511 of fulcrum and moves up or down by picking up (pickup) screw actuator 433.More particularly, by screw actuator arm 512, lever retainer 513, separator levers 514 with depart from roller retainer 406, departing from roller 407 can raise or reduce by picking up solenoidal on/off operation.

When paper S is sent to process disk 410, the screw actuator 433 that picks up as position control is connected, so that by screw actuator arm 512, lever retainer 513, separator levers 514 with depart from roller retainer 406 and make and depart from the upper position that roller 407 moves to the transmission that does not hinder paper S, therefore, paper S is sent on the process disk 410 with can not departed from roller 407 obstruction.

Also have, depart from roller 407 by synchronous belt 523, roller gear 524, idle gear 525, depart from gear 526, depart from belt pulley 527 and synchronous belt 522 and drive by transmitting motor 431, can rotate forward or backward, be used to drive transfer roller 405, as shown in Figure 4, and this depart from roller 407 by the rotation that transmits motor 431 along direction of transfer (hereinafter being called rotation forward) or along and sender's (contrarotation) rotation in the opposite direction, and rotation amount is corresponding with the rotation amount of transmission motor 431.

In the present embodiment, inlet sensor 403 shown in Fig. 2 detects the paper that is transmitted, and when paper is transmitted preset distance by transfer roller 405, picking up screw actuator 433 closes, therefore depart from roller 407 and reduce,, rotate along paper conveyance direction simultaneously so that drop on (being resisted against) paper by its weight, transmit this paper then at the fixed time, and at the fixed time again along contrarotation.

This contrarotation makes the rear end of paper be resisted against behind the paper on the end stop 411, behind this paper end stop 411 be arranged in vertically process disk 410, along the upstream extremity of direction of transfer, and as limiting part, be used to limit the position of paper S, thereby paper S is alignd along direction of transfer along paper conveyance direction.

In Fig. 4, represented: location wall 416, this location wall 416 constitutes the transverse end limiting part, is used for the end position of restriction along the paper of the direction vertical with paper conveyance direction (hereinafter being called direction); And stapling unit 420, this stapling unit 420 is positioned near the location wall of process disk 410, and constitutes binding apparatus, and this binding apparatus is bound processing to the stacks of sheets that is formed on the process disk 410.By departing from motor gear 432a, departing from miniature gears 516 and offset track 515, departing from roller 407 can broad ways move and approaching location wall 416 by the driving that departs from motor 432, this departs from motor 432 can be forward or contrarotation, and constitute running gear with departing from roller 407 to cooperate.

When departing from roller 407 near location wall 416, transmit towards location wall 416 by the friction force that departs from roller 407 along the paper of direction of transfer alignment by being resisted against behind the paper on the end stop 411, and under by the situation of paper pressing component 510 bending with sizings, being resisted against on the wall 416 of location, thereby broad ways location at place, paper end.After paper S is resisted against on the wall 416 of location, depart from roller 407 towards location wall 416 motion (on paper, sliding) scheduled volumes, stop then.

Because such roller 407 that departs from is arranged, depart from roller 407 and the paper that is expelled on the process disk 410 is transmitted towards the stacking dish by making along paper conveyance direction rotation (shown in Fig. 5 A), make this paper return end stop 411 behind paper by the contrarotation (shown in Fig. 4 B) that departs from roller 407 then, and make this paper alignment on the end stop 411 of back by the rear end is resisted against.

In Fig. 5 A to 5C and Fig. 6 A, 6B, 7A, 7B and 22 (back will be introduced), introduced such structure, wherein, with different among Fig. 4, depart from roller 407 and be arranged in and depart from roller retainer 406 inside, but should difference be design distinguished, as broad as long shown in the function of this structure and Fig. 4.

Then, depart from roller 407, shown in Fig. 5 C, thereby make end paper S, broad ways be resisted against on the wall 416 of location moving towards location wall 416 with paper S state of contact lower edge off-axis 511, and the alignment of paper S broad ways.

On the other hand, with reference to figure 4, paper hold assembly 412 is as paper (stacking) holding device, and it pushes the rear end part of the paper S that has alignd from above by the biasing force of biasing device 560.When the alignment of paper S broad ways is alignd in the rear end then (back will be introduced), and when after make (as shown in Figure 6A) when departing from roller 407 and raising by picking up screw actuator 433, above paper hold assembly 412, push the paper S of such alignment, shown in Fig. 6 B.

Pushing paper S like this can be held in a predetermined position discharging (transmission) to the paper on the process disk 410 from above, and the influence of the paper S that can not be subjected to transmitting subsequently or move by the paper S that transmits subsequently.

When departing from roller 407 contrarotations, paper hold assembly 412 rotates up, as shown in Figure 7A, so that receive paper S, when paper S with departing from roller 407 broad wayss motions when being used for end part aligning, paper hold assembly 412 also rotates up, shown in Fig. 7 B, so that do not constitute the load that stops sheet movement.

In Fig. 8 A and 8B, stacks of sheets is discharged parts 413 and is expressed as the example that the sheet processed stacking is expelled to the eduction gear on stacking dish (bottom storage tank) 421 or the stacking dish (top storage tank), this stacks of sheets is discharged rotatably supporting paper hold assembly 412 of parts 413, and make the stacks of sheets of alignment or the stacks of sheets of alignment and bookbinding under the state that keeps by paper hold assembly 412, move towards the stacking dish that is arranged in process disk 410 downstreams (bottom storage tank) 421 or stacking dish (top storage tank) 422, as shown in Figure 9.

Then, when arriving the fore-end (this fore-end is formed in the paper drain position of representing with solid line among Fig. 9) of process disk 410, stacks of sheets is discharged parts 413 and is stopped under the state that by paper hold assembly 412 stacks of sheets SA is remained on stacking

dish

421 or 422, end stop 411 returns behind the paper then, discharge paper hold assembly 412 simultaneously and act on maintenance effect on the stacks of sheets SA, thereby stacks of sheets SA is fallen.This structure allows to use the process disk 410 and the stacking dish 421,422 (shown in Fig. 2,9) of basic horizontal angle (about 10 ° or littler), rather than the inclination stacking dish of prior art (angle is about 30 °).This can obtain stable stacking ability in finite space, even the stacking dish for example in the present embodiment has smaller angle (for example about 9 °) also can obtain stable stacking ability.

Also have, the stacks of sheets SA that discharges and be stacked on the stacking dish 421,422 is pushed by the pressing component 421A (as shown in Figure 2) as sheets pressing device.Push stacks of sheets SA like this by pressing component 421A and not only can prevent, and prevent that the paper of stacking reduces stacking performance (for example stacked location moves) owing to being subjected to the promotion of paper subsequently owing to paper bending reduces the stacking performance.Therefore, (as present embodiment) obtains stable stacking characteristic under can be in the angle of the stacking dish very little situation, rather than as the prior art stacking dish of above-mentioned about 30 ° of angles.

Below with reference to Fig. 8 A and 8B, the pin A 553a and the B 554a that are arranged on cliding gear A 553 and the B 554 (this cliding gear A 553 and B 554 discharge motor 430 driven in rotation by belt 551 and belt pulley 552 by stacks of sheets) are integral rotation with this cliding gear A 553 and B 554, and move in the unshowned guide slit in being formed at stacks of sheets discharge parts 413 along with moving of this cliding gear.

In this structure, stacks of sheets is discharged parts 413 and is moved between near the initial position (shown in Fig. 8 A) the end stop 411 at the paper drain position (shown in Fig. 8 B) that leads to stacking dish (bottom storage tank) 421 or stacking dish (top storage tank) 422 and after being in paper by stacks of sheets discharge motor 430 and along slide rail 555.Usually, stacks of sheets discharge parts 413 are fixed on initial position by the energising of stacks of sheets discharge motor 430.

With reference to Figure 10, when departing from roller 407 and after paper transmits, stop the rotation or when departing from roller 407 broad wayss and move, be used to make the clamping spiral tube 434 of paper hold assembly 412 rotations to connect, thereby make paper hold assembly 412 rotate up by lever 434a on paper hold assembly 412 and trip lever part 412a.

Pressing component 421A receives by being arranged in cliding gear B 554 following cam B 554b and passes through pressing component 556, lever segment 557 and coil spring 558 and transferring power (shown in Figure 11 A), thereby is rotated.Also have, under the state of transferring power not, pressing component 421A is positioned at the state of stepping back from the stacks of sheets surface of stacking dish 421,422 by line of return coil spring 559, shown in Figure 11 B.

In this structure, stacks of sheets discharge cliding gear A 553 that parts 413 cause by the rotation of being discharged motor 430 by stacking and B 554 rotation and after being expelled to stacks of sheets on the stacking dish 421,422, when the pressing function of cam B 554b release action on pressing component 556, pressing component 421A takes to make that by line of return coil spring 559 stacks of sheets can drop on the lip-deep state of stacking of stacking dish 421,422.

Then, when stacks of sheets drops on the stacking dish 421,422, and when stacks of sheets discharge parts 413 are back to back end stop 411, cam B 554b below cliding gear B 554 drives pressing component 556, thereby make pressing component 421A rotation by lever part 567 and coil spring 558, and make pressing component 421A keep this stacks of sheets.

In the present embodiment, move (as mentioned above) afterwards, depart from roller 407 and when stopping alignment operation, reverse once more,, thereby realize the alignment of degree of precision so that proofread and correct the error of paper conveyance direction in paper S broad ways.Then, when the paper that specifies number was finished registration process, clamping spiral tube 434 was closed paper hold assembly 412, thereby kept stacks of sheets.

When stacking dish 421, but be arranged in to 422 perpendicular movements stacks of sheets space S P1 (back will be introduced) when interior (as at present embodiment), and stacking

dish

421 or 422 for a certain reason and and do not stop at the desired location, but under the situation that continues to raise, not only the stacking dish 421,422 or this stacking dish 421, the paper of stacking may be against top stacking dish on 422, and the paper on the stacking dish of top side (top storage tank) 422 or this stacking dish 422 also may be resisted against on the basal surface (with reference to figure 1) of reader part 120 upper surface of this basal surface formation stacks of sheets space S P1.Therefore, in the present embodiment, provide upper limit sensor 547, as the sensor (back will be introduced) of the motion that is used to limit stacking dish (top storage tank) 422.

But, when existing foreign matter or a large amount of stacks of sheets when stacking dish (top storage tank) is gone up, this foreign matter or paper may be resisted against on the upper surface of stacks of sheets space S P1 before upper limit sensor 547 detects stacking dish (top storage tank) 422.

When carry out like this at foreign matter or paper against after when continuing rising stacking dish (top storage tank) 422, may cause foreign matter, paper or stacking dish (top storage tank) 422 to break, but in the present embodiment, coil spring 561 is arranged between holding tray motor 530 and stacking dish (the top storage tank) 422 (421) (as previously mentioned) as restraint device, therefore, when the moment of torsion of rising stacking dish (top storage tank) 422 surpasses predetermined torque, the propulsive effort of holding tray motor 530 will not pass to stacking dish (top storage tank) 422.

More particularly, when foreign matter or paper are resisted against on the upper surface of stacks of sheets space S P1, when producing the load that surpasses coil spring 561 set moments of torsion then, belt pulley 532 with holding tray motor 530 rotations slides around S. A. 533, therefore, being configured for the S. A. 533 that propulsive effort with holding tray motor 530 passes to the axle drive shaft of stacking dish (top storage tank) 422 will stop, thereby stacking dish (top storage tank) 422 is no longer raise.Also have, even when when still not detecting stacking dish (top storage tank) 442 through upper limit sensor 547 after the schedule time, CPU 100 (back will be introduced) stops the driving of holding tray motor 530, thus the stacking dish that tops out (top storage tank) 422.

Therefore, when foreign matter or paper are resisted against on the upper surface of stacks of sheets space S P1, the rising of coil spring 561 restriction stacking dishes (top storage tank) 422, thus avoid stacking dish (top storage tank) 422 or be stacked in paper on this stacking dish etc. breaking.

A. 533.

In this structure, when having foreign matter, finishing the load before that raises at stacking dish (top storage tank) 422 increases, and when load stopped above S. A. 533 under the situation of predetermined torque, the on/off operation of rotation sensor 564 stopped.When detecting this variation, CPU 100 stops driving tray motor 530, thus the stacking dish that tops out (top storage tank) 422.

To introduce the dish conversion operations of stacking dish (bottom storage tank) 421 and stacking dish (top storage tank) 422 below.

Stacking dish (bottom storage tank) 421 and stacking dish (top storage tank) 422 can be raise by holding tray motor 530 by rack and pinion or reduce independently, as described in earlier in respect of figures 12.This structure that has the individual drive source and can raise independently and reduce makes stacking dish (bottom storage tank) 421 and stacking dish (top storage tank) 422 can selectively receive by stacks of sheets and discharges the paper treated that parts 413 are discharged.

In the state shown in Fig. 1 or 2 (wherein, a plurality of (n, being 2 in the present embodiment) stacking dish (stacks of sheets device) is positioned at the both sides of paper discharge orifice 400A, this paper discharge orifice 400A is used for discharging parts (eduction gear) by stacks of sheets and discharges paper), because a spatial destribution is below stacking dish (bottom storage tank) 421, therefore can a large amount of paper of stacking, even and, so can also the more substantial paper of stacking because also can pile up neatly at the enterprising windrow of top storage tank by conversion upper and lower storage tank (back will be introduced) when stacking dish (top storage tank) 422 is in when stepping back state.

To introduce below when stacking dish (bottom storage tank) 421 is in the position that can receive paper and stacking dish (top storage tank) 422 and steps back to upside (Figure 13 A), and make stacking dish (top storage tank) 422 move to the operation that can below paper discharge orifice 400A, receive the position of paper.

Below stacking dish (bottom storage tank) 421, the lower limited sensor 546 that can detect lower limit is arranged, and in this operation, stacking dish (bottom storage tank) 421 at first is reduced to the position of being detected by lower limited sensor 546.

Then, attraction spiral tube 433 shown in Fig. 4 is connected, so that make and depart from roller 407 and move to top and wait the position by departing from roller retainer 406, shown in Figure 14 A, under this state, connect magnetic clutch 517 then, so that connect the driving that transmits motor 431, then, transmit motor 431 rotation scheduled volumes, so that reduce flashboard 521, as shown in Figure 14B by gear parts 517a, idle gear 518, cam wheel 519 and the flashboard lever 520 of magnetic clutch 517.

Reduce flashboard 521 like this so that close the paper discharge orifice 400A of process disk 410, to be formed for the guiding surface (Figure 15 A) of paper rear end, thereby prevented at mobile stacking dish (top storage tank) that the paper that is stacked in this stacking dish from oppositely entering process disk at 422 o'clock.

Then, when finishing the reduction of flashboard 521, stacking dish (top storage tank) 422 begins to reduce, and stops at certain position (Figure 15 B) after through pressing component 421A.Then, flashboard 521 raises and also stops at correct position, and then, the pressing component 421A that steps back moves to the state that can push paper, and stacking dish (top storage tank) 422 raises, and stops (Figure 16 A) after moving to the position that is used to receive paper.Moving to this position makes it possible to as receive paper in stacking dish (bottom storage tank) 421.

When imaging apparatus body 500A understood the antiquarian of being discharged by paper discharge section 208, control part that be made of microcomputer system, paper processing device 400 can be communicated with by connecting with the control part of imaging device main body 500A understood the size of inserting the paper in the process disk 410.

Therefore, discharge the paper S of (transmission) from imaging device main body 500A for each, the control part of paper processing device 400 (CPU 100) is all recognized the size of this paper, and controls and depart from motor 432, thereby control departs from the amount of exercise of roller 407 broad wayss.Therefore, the amount of exercise that departs from roller 407 is corresponding with the size of paper S in inserting process disk 410, thereby makes the sidepiece of paper be resisted against really on the wall 416 of location.

In the present embodiment, because the stacks of sheets on stacking dish 421 constitutes the part of process disk 410, therefore as stacks of sheets SA during from process disk 410 discharges, stacking dish 421 raises by the stacking dish and reduces motor (holding tray motor) (with reference to Figure 12) and reduce, and mates with process disk 410 up to the surface, top side of the paper of stacking is basic.

Introduce the paper process operation of present embodiment paper processing device 400 as constituted above below with reference to the diagram of circuit shown in Figure 20 and 21.

At first, when imaging apparatus body 500A began imaging operation, the CPU 100 (with reference to Figure 19) of paper processing device 400 differentiated whether receive paper discharge signal (S100) from imaging device main body 500A.When having received paper and discharge signal (being Y among the S100), pick up screw actuator 433 and connect (S110), so that upwards pulling departs from roller 407 by what depart from 406 supportings of roller retainer.

Then, transmit motor 431 and connect (S120), so that make the transfer roller 405 that is arranged on the paper drain passageway to transmit paper along discharging the identical direction of direction with the paper of imaging device main body 500A.Then, the front end of first paper is through inlet sensor 403 and connect this sensor (being Y among the S130), paper arrives transfer roller 405 then, thereby receive propulsive effort from this transfer roller 405, and when paper leaves the paper discharge section 208 (with reference to figure 1) of imaging device main body 500A, finish the paper transmission.

Then, paper sends process disk 410 to by transfer roller 405, and makes before paper leaves transfer roller 405 and pick up screw actuator 433 and disconnect (S150), thereby makes that departing from roller 407 drops on the paper by its weight.Then, shown in Fig. 5 A, paper S is sent to desired location (S160) by departing from roller 407.(be Y among the S160) when paper is sent to the desired location, the rotation that transmits motor 431 stops (S170), so that stop to transmit paper S.

Then, when the rotation that departs from roller 407 stopped, clamping screw actuator 434 was connected (S180), thereby opened the paper hold assembly 412 that is arranged near the initial position the end stop 411 behind the paper, shown in Fig. 5 B.Then, transmit motor 431,, thereby the rear end of paper is resisted against behind the paper on the end stop 411 so that retract paper S (S190) by departing from roller 407 along reversing in the opposite direction with the sender.

The rotation amount that departs from roller 407 on the end stop time after the rear end that makes paper is resisted against paper is selected like this, promptly consider in the deflection of the paper S that when imaging device main body 500A transmits, may cause and supply with, will make conveying capacity be back to the distance of end stop 411 behind the paper less times greater than the position that stops from paper S.Therefore, even after transmitting, depart from roller 407 and still rotate the schedule time, paper S is resisted against behind the paper on the end stop 411.

Like this, paper S can be resisted against behind the paper on the end stop 411 really.When paper in contrarotation should the process of the schedule time is resisted against on the end stop 411 of back, depart from roller 407 on paper, dally (slip).

Then, be used to the size of the paper of being discharged be verified (S200) from the dimension information of imaging apparatus body 500A, and calculate according to the size of the paper S that discharges and to depart from displacement, this departs from the displacement that displacement is a paper S broad ways, is that the paper S that will be expelled on the process disk 410 locatees on the wall 416 required (S210) by being pressed in.

Drive then and depart from motor 432 so that starting departs from the bias motion (S220) of roller 407.When departing from roller 407 such motions, depart from roller 407 towards 416 motions of location wall by the friction force that departs from roller 407 with this with the paper S that departs from roller 407 contacts.Under this state, paper hold assembly 412 rotates up, shown in Fig. 7 B, so that can not form load to the motion of paper S.

Depart from roller 407 and carry out bias motion like this by making, paper is resisted against on the wall 416 of location, shown in Fig. 5 C, thereby makes the alignment of paper S broad ways.After making that paper S is resisted against on the wall 416 of location, depart from roller 407 certain hour that on paper S, slides, stop then.Then,, depart from roller 407 and reverse once more, retract the alignment operation (S230) of paper S so that carry out, thereby finish the alignment of the first paper S in order to proofread and correct after bias motion along the alignment deviation of direction of transfer.

Then, when finishing the alignment of the first paper S like this, pick up screw actuator 433 and open (S240), depart from roller 407, as shown in Figure 6A, and disconnect clamping screw actuator (S250) so that raise.Therefore, paper hold assembly 412 is closed, and shown in Fig. 6 B, so that the paper that clamps and keep having alignd, therefore, the paper that the paper that prevents from first to discharge is discharged by the next one drives.

Then, shown in Fig. 6 B, in the rising state, depart from roller 407 by departing from motor 432 and returning initial position by rack-and-pinion.

Then, whether inspection is contained in paper S on the process disk 410 is last page or leaf corresponding final paper (S270) with the original paper that is used to duplicate, when being not last paper (being N among the S270) according to the information judgement that transmits by imaging device main body 500A, program is returned step S100, discharge signal so that receive the paper that transmits by imaging device main body 500A, and repeating above-mentioned flow process, paper S to the last packs in the process disk 410.

In this structure, when from imaging device main body 500A, discharging paper S at every turn, the control part of paper processing device 400 (CPU) identification paper S, and calculate the bias motion amount that is applicable to this paper S.Therefore, and depart from the paper S that roller 407 contacts and align, and align with location wall 416 according to the amount of exercise that is calculated.

On the other hand, when judging that paper is last paper (being Y among the S270), on process disk 410, form the stacks of sheets consistent with the original paper that is used to duplicate.Then, check and whether selected bookbinding to handle (S280), when having selected, (be Y among the S280), drive binder unit 420, so that in gutter pos shown in Figure 22, bind processing.

When (being N among the S280) do not handled in the selection bookbinding or after finishing the bookbinding processing, under the state of stacks of sheets SA by 412 clampings of paper hold assembly, stacks of sheets discharge parts 413 are discharged motor 430 by stacks of sheets and are advanced towards stacking dish 421, thereby discharge stacks of sheets SA (S300).

Then, the motion (reduction) of synchronously carrying out stacking dish 421 with the discharging operation of stacks of sheets SA (S310) makes stacks of sheets discharge parts 413 then and is back to initial position (S320).Then, transmit motor 431 and stop,, and pick up screw actuator 433 disconnections (S340), depart from roller 407 so that reduce, thereby finish series of steps so that stop transfer roller 405 and depart from the rotation (S330) of roller 407.

As previously mentioned, the rotation amount that after the rear end that makes paper is resisted against paper, will depart from roller on the end stop 411 time be chosen as make conveying capacity less times greater than the position that stops from paper S to the distance of end stop 411 after be back to paper, even promptly by transmitting one along contrarotation and with paper S and still make after the distance on the end stop 411 after being used to make the paper rear end be resisted against paper and depart from roller 407 along contrarotation departing from roller 407, paper S can be resisted against behind the paper on the end stop 411 really.

Like this, just can make paper S along the stable alignment of paper conveyance direction by the simple structure that does not need a lot of parts.And do not discharge because of paper, so paper can be stablized transmission under the situation of very little position deviation in the mode of waving.

In above stated specification, when bookbinding one stacks of sheets, depart from the effect that roller 407 plays sorting plant, and after stacks of sheets is resisted against on the wall 416 of location, bind processing, but when not binding processing, paper can be discharged under not by the situation that departs from roller 407 selections.
