Fig. 4 represents that first page sheet material S is positioned in the schematic isometric of the situation on post-processing dish 11.
The large scale sheet material S that the length that the figure shows on sheet material throughput direction is greater than reaction plate 21 with the state across reaction plate 21 and wobble-plate 22 by the example of situation loaded.
Before sheet material S is positioned on post-processing dish 11, CD datum plate 12,29 move to the reference position shown in this figure from reference position, when sheet material S is positioned on post-processing dish 11, in order to carry out FD alignment, FD align unit 14 moves to the FD aligned position of the sheets of sizes corresponding to sheet material S along direction shown by arrow Y from reference position.
FD aligned position is equivalent at sheet material throughput direction and stop part 18a, the position of length (sheet length) L on the throughput direction of 18b distance sheet material S, representing the size (A4 etc.) of sheet material S and the sheet material information of conveying attitude (vertical or horizontal) by obtaining from image processing system 1, determining FD aligned position.
At this, the longitudinal direction conveying attitude of so-called sheet material S is, in the long limit and minor face of sheet material S, the attitude when attitude feeding sheets S of sheet material throughput direction with long edge, so-called lateral transfer attitude is, with the minor face of sheet material S along the attitude when attitude feeding sheets S of sheet material throughput direction.
By FD align unit 14 is moved to FD aligned position, sheet material S on post-processing dish 11 is pushed to direction shown by arrow Y by FD align unit 14, the throughput direction front end Sf becoming sheet material S abuts with FD align unit 14 and the state that abuts of the throughput direction rear end Se of sheet material S and stop part 18a, 18b.Thus, on post-processing dish 11, with the position of stop part 18a, 18b for benchmark, sheet material S is aligned on sheet material throughput direction (FD alignment).
FD aligns end, and then in order to carry out CD alignment, CD alignment plate 13 moves to the CD aligned position of the sheets of sizes corresponding to sheet material S along the direction (direction of facing device rear side) shown in arrow A from reference position.
CD aligned position be equivalent on device fore-and-aft direction with the position of CD datum plate 12 apart from length (sheet width) W on the Width of sheet material S, determine this CD aligned position by obtaining sheet material information from image processing system 1.
CD aligned position is moved to by CD alignment plate 13, sheet material S on post-processing dish 11 is pushed to the direction shown in arrow A by CD alignment plate 13, the lateral margin Sc become on the Width of sheet material S abuts with CD alignment plate 13 and the state that abuts of another lateral margin Sd and CD datum plate 12,29.Thus, on post-processing dish 11, with the position of CD datum plate 12,29 for benchmark, sheet material S is aligned on device fore-and-aft direction (CD alignment).
FD align unit 14 stops certain hour (such as 100ms) after moving to FD aligned position, when terminating the FD alignment of first page sheet material S, be back to from the position of FD aligned position distance predetermined distance (such as 10mm, 15mm) standby.CD alignment plate 13 also stops certain hour (such as 100ms) after moving to CD aligned position, when CD alignment terminates, be back to from the position of CD aligned position distance predetermined distance (such as 10mm, 15mm) standby, wait for that ensuing second page sheet material S is fed through post-processing dish 11 from image processing system 1.In addition, when sheet material S is first page, also can omit CD alignment.
When second page sheet material S is admitted on post-processing dish 11, be loaded into the state on the first page sheet material S aliging complete at second page sheet material S under, again carry out above-mentioned FD alignment and align with CD.Till the feeding of all N hinge material S is complete, the feeding for each hinge material S repeats FD alignment and aligns with CD.Thus, post-processing dish 11 loads multipage sheet material S with the state of alignment.
Fig. 5 represents to load N hinge material S and the schematic isometric of state that the sheet bundle Sb that formed is aligned on post-processing dish 11.When terminating the alignment of all N hinge material S, FD align unit 14 is mobile to direction shown in arrow X (sheet material throughput direction), is back to reference position.CD datum plate 12,29 moves to the position of distance sheet material end 2mm.
Then, FD transfer unit 15 is moved from reference position to direction shown by arrow X, the sheet bundle Sb that will be clipped by CD datum plate 12,29 and CD alignment plate 13 is delivered to the gutter pos of binder mechanism 103 along direction shown by arrow X, then stop FD transfer unit 15.For sheet bundle Sb being delivered to the miles of relative movement of the FD transfer unit 15 of gutter pos, determine by referring to the gutter pos information in advance sheets of sizes is mapped with miles of relative movement.
Fig. 6 represents that sheet bundle Sb is delivered to gutter pos by FD transfer unit 15 and the schematic isometric of situation about stopping.When sheet bundle Sb is in halted state, binder mechanism 103 utilizes binding stable Sz (Fig. 7) to bind.
After bookbinding, as shown in Figure 7, FD transfer unit 15 is moved to direction shown by arrow X further, will by CD datum plate 12, the 29 sheet bundle Sb clipped with CD alignment plate 13 are delivered to its throughput direction rear end Se and are positioned at end 22c than the sheet material throughput direction upstream side of wobble-plate 22 again to the position (transmitting place) of downstream lateral extent predetermined distance, then stop FD transfer unit 15.
The sheet bundle Sb after alignment is delivered to distance required for gutter pos as L1, will from stop part 18a, 18b to the distance of rear end Se of sheet bundle Sb being positioned at transmitting place as L2 time, the miles of relative movement for making sheet bundle Sb be delivered to the FD transfer unit 15 of transmitting place is obtained according to the difference i.e. size of distance (L2-L1) of L1 and L2, but because can L1 be pre-determined according to the size of sheet material S, and can L2 be pre-determined, so, if know the size of sheet material S, the miles of relative movement of FD transfer unit 15 also can be determined.
By the conveying of this sheet bundle Sb to transmitting place, sheet bundle Sb is in and is positioned on wobble-plate 22 instead of the state be positioned on reaction plate 21.
When sheet bundle Sb terminates to the conveying of transmitting place, as shown in Figure 8, the guiding pawl 16 of wobble-plate 22 at the end 22c of sheet material throughput direction upstream side is configured at, 17 by the Posture exchange that submerges for outstanding attitude, afterwards, FD transfer unit 15 moves to arrow Y-direction, is back to reference position.
The guiding pawl 16,17 giving prominence to attitude, the position relationship being positioned at the rear end Se of the sheet bundle Sb of transmitting place and the end 22c of wobble-plate 22 are that the guiding pawl 16,17 of outstanding attitude is between the rear end Se and the end 22c of wobble-plate 22 of this sheet bundle Sb.
FD transfer unit 15 moves to arrow Y-direction, the sheet bundle Sb be positioned on the wobble-plate 22 of lateral attitude will break away along the reaction plate 21 that is tilted to of wobble-plate 22, but by utilizing the guiding pawl 16,17 of outstanding attitude to limit its landing, can be maintained it and be positioned in state on wobble-plate 22.
Then, carry out CD alignment plate 13 being moved to device face side and being back to the action of reference position, as shown in Figure 9, to be positioned at the fulcrum 22b of wobble-plate 22 in the end of sheet material conveyance direction downstream side for fulcrum, lift the end 22c of sheet material throughput direction upstream side, wobble-plate 22 transition making lateral attitude is horizontal attitude.
Position relationship on above-below direction can pre-determine, that is, when wobble-plate 22 becomes horizontal attitude, in the sheet material mounting surface 22a of wobble-plate 22, the whole lateral margin 22g of device face side is positioned on the upper end 53 of the standing wall portion 51b of the second incorporating section 102.
CD datum plate 12, binder mechanism 103 and guiding pawl 16,17 swing integratedly with wobble-plate 22, and CD alignment plate 13 and CD datum plate 29 are because be supported on reaction plate 21, so do not swing integratedly with wobble-plate 22.
When wobble-plate 22 is in horizontal attitude, the magnitude relationship of wobble-plate 22 hunting range in the vertical direction and CD alignment plate 13 height in the vertical direction is also determined in advance, and the upper end 131 of CD alignment plate 13 is positioned under wobble-plate 22.
In addition, when wobble-plate 22 is in lateral attitude, in the lateral margin 22g of the device face side of sheet material mounting surface 22a, the end of sheet material conveyance direction downstream side and the edge 22m (the first side edge part) of end side are positioned on the upper end 53 of the standing wall portion 51b of the second incorporating section 102, and the end i.e. edge 22n of another side (the second side edge part) of sheet material throughput direction upstream side is positioned under the upper end 53 of standing wall portion 51b.
When wobble-plate 22 becomes horizontal attitude, CD datum plate 12 is removed with the engaging of datum plate 29, only has CD datum plate 29 to be back to reference position because of the application force of extension spring 28.
When the transition of wobble-plate 22 to horizontal attitude terminates, as shown in Figure 10, CD datum plate 12 moves from device back side lateral device face side on the direction shown in arrow B.Thus, be positioned in and be in the positive face 51 of the sheet bundle Sb on the wobble-plate 22 of horizontal attitude to device face side on the upper end 53 of standing wall portion 51b and transferred.When wobble-plate 22 is in horizontal attitude, because wobble-plate 22 is positioned on CD alignment plate 13, so sheet bundle Sb can not be hindered by CD alignment plate 13 to the transfer of device face side.
When CD datum plate 12 moves to device face side foremost, as shown in figure 11, be positioned at the sheet bundle Sb be on the wobble-plate 22 of horizontal attitude and move to positive face 51, be positioned on the sheet material mounting surface 51a of positive face 51.
Although the sheet bundle Sb be positioned on the sheet material mounting surface 51a of positive face 51 is tilted to the landing of device rear side along sheet material mounting surface 51a, but the lateral margin Sd of the device rear side of sheet bundle Sb (front end in landing direction) abuts with the standing wall portion 51b being erected on device rear side, thus the landing of sheet bundle Sb can be limited by standing wall portion 51b.
Thus, static under the state that the sheet bundle Sb on sheet material mounting surface 51a abuts with standing wall portion 51b at the lateral margin Sd of its device rear side.This represents that standing wall portion 51b plays a role as the limiting unit of the sheet bundle Sb on restriction sheet material mounting surface 51a.
In addition, as long as the sheet bundle Sb be on the wobble-plate 22 of horizontal attitude can be transferred to the sheet material mounting surface 51a of positive face 51 and not stopped by standing wall portion 51b, upper end 53 position relationship in the vertical direction of the sheet material mounting surface 22a of the wobble-plate 22 being in horizontal attitude and standing wall portion 51b then also can be made to become, such as, the lateral margin 22g of sheet material mounting surface 22a and the upper end 53 of standing wall portion 51b become same position, replace aforesaid position relationship with this.
In addition, as long as can transfer the attitude (transfer attitude) of sheet bundle Sb, be then not limited to horizontal attitude, such as, wobble-plate 22 also can adopt and make the lateral margin of its device rear side be positioned at the attitude that leans forward on the lateral margin 22g of its device face side.This is beyond the swinging gear of the above-below direction of wobble-plate 22, just can realize by assembling the mechanism that can lean forward to device fore-and-aft direction.
When user specifies bookbinding multi-section sheet bundle, the alignment of sheet bundle Sb, bookbinding, wobble-plate 22 carry out in units of portion successively to the transition of horizontal attitude, a succession of process from wobble-plate 22 to the transfer of positive face 51.
In this case, as shown in the drawing, when first sheet bundle Sb is incorporated in positive face 51, be configured in the pressing jaw 52 in the notch 51c of standing wall portion 51b to give prominence to from the notch 51c of standing wall portion 51b, make first the sheet bundle Sb being accommodated in positive face 51 be in the hold mode being pressed pawl 52 and pushing down from top.
Pressing jaw 52 turned back to original position of submerging (Fig. 3) before second sheet bundle Sb is transferred to positive face 51.The action case of haunting of this pressing jaw 52 is grabbed as the pressing by being made up of screw actuator and is driven the propulsive effort of actuating mechanism 37 (Figure 12) to carry out.At this, if pressing jaw drives actuating mechanism 37 to be driven, the front end of pressing jaw 52 is just given prominence to from standing wall portion 51b and presses sheet bundle Sb, if this driving is stopped, is then back to by the application force of extension spring (not shown) position of submerging.
When second sheet bundle Sb is transferred to positive face 51, when being loaded with second sheet bundle Sb on first the sheet bundle Sb being accommodated in positive face 51, by four pressing jaw 52, the hold mode again becoming two sheet bundle Sb that pressing has been loaded.Afterwards, when proceeding the bookbinding in units of portion's number, repeat above-mentioned action to every portion sheet bundle, when task terminates, pressing jaw 52 is back to position of submerging, and removes the hold mode of this pressing.In addition, if only bind a sheet bundle, then, after only once being pressed by pressing jaw 52 couples of sheet bundle Sb, pressing jaw 52 is back to position of submerging.
Thus, more than one sheet bundle Sb after bookbinding received by the positive face 51 being configured at device face side, user can take out from device face side the sheet bundle Sb being accommodated in positive face 51 easily.
In addition, when sheet bundle Sb terminates from wobble-plate 22 to the transfer of positive face 51, CD datum plate 12 is back to reference position from device front lateral device rear side.When CD datum plate 12 is back to reference position, wobble-plate 22 declines and reverts to lateral attitude.
When CD datum plate 12 correcting action, the projection 12a (Fig. 3) of CD datum plate 12 is positioned at the rear side of the CD datum plate 29 being in reference position, when CD datum plate 12 moves to device face side again, projection 12a abuts with the face 29a of the device rear side of CD datum plate 29, thus, the fastening state of CD datum plate 12 and CD datum plate 29 is again in.
In the above description, although the description of example when performing the task of binding sheet bundle Sb, but such as when execution prints multipage sheet material S and do not bind, except bookbinding, carry out the alignment of sheet bundle Sb same as described above, to the conveying of wobble-plate 22, wobble-plate 22 to the transition of horizontal attitude, from wobble-plate 22 to the transfer of positive face 51.
In addition, such as, when only printing the task of one page sheet material S, carry out process same as described above except alignment and bookbinding, that is, carry out to the conveying of wobble-plate 22, wobble-plate 22 to the transition of horizontal attitude, from wobble-plate 22 to the transfer of positive face 51.

In addition, control part 104 receives and detects from being used for the detection signal that CD datum plate 12 is positioned at the reference position detecting sensor 31 (Figure 10) of reference position, detects CD datum plate 12 and whether is positioned at reference position.
Reference position detecting sensor 31 such as uses the optical pickocff with illuminating part and the light accepting part be arranged at intervals.
When using this optical pickocff, following method of inspection can be adopted.
Namely, when CD datum plate 12 is positioned at reference position, the shield member (not shown) with the movement of CD datum plate 12 one is there is between illuminating part and light accepting part, thus, carry out the light conductively-closed of self-luminescent part and can not be received at light accepting part, reference position detecting sensor 31 exports OFF signal, when CD datum plate 12 have left reference position, this shield member leaves between illuminating part and light accepting part, thus, the light of self-luminescent part can be received at light accepting part, thus, reference position detecting sensor 31 exports ON signal.
Control part 104 is ON signal or OFF signal by detecting what export from reference position detecting sensor 31, can detect that CD datum plate 12 is positioned at reference position or not in reference position.The method of inspection of reference position also can be other method of inspection.For following other illustrated reference position detecting sensors 32 ~ 35, the method for inspection of identical reference position also can be adopted.
And then control part 104 receives and detects from being used for the detection signal that CD alignment plate 13 is positioned at the reference position detecting sensor 32 of reference position, detects CD alignment plate 13 and whether is positioned at reference position.
In addition, control part 104 receives and detects from being used for the detection signal that FD align unit 14 is positioned at the reference position detecting sensor 33 of reference position, detects FD align unit 14 and whether is positioned at reference position.
And then control part 104 receives and detects from being used for the detection signal that FD transfer unit 15 is positioned at the reference position detecting sensor 34 of reference position, detects FD transfer unit 15 and whether is positioned at reference position.
In addition, control part 104 receives and is in the detection signal of the reference position detecting sensor 35 of lateral attitude (reference position) from being used for wobble detection dish 22, and whether wobble detection dish 22 is positioned at reference position.
And then control part 104 can exchange data and information with the control part 6 of image processing system 1, obtain the various information such as appointment and the sheet material information that detects at image processing system 1 of instruction that carrying out that user sends bind, portion's number from control part 6.
The content > that the bookbinding that < carries out at sheet post-processing apparatus 2 controls
Figure 13 and Figure 14 represents that the bookbinding carried out at sheet post-processing apparatus 2 controls the diagram of circuit of content, performs when control part 104 receives bookbinding instruction from the control part 6 of image processing system 1.
As shown in figure 13, the sheet material information (step S1) of the sheet material S discharged by image processing system 1 is obtained.
Then, CD datum plate 12 is moved to reference position (step S2) from reference position.
The movement of CD datum plate 12 drives transfer motor M4 to carry out by rotating forward with predetermined rotation number or angle of rotation, and described predetermined rotation number or angle of rotation are equivalent to reference position to the rotation number of the transfer motor M4 of the predetermined distance of reference position or angle of rotation.By the movement of CD datum plate 12 to reference position, CD datum plate 29 also moves to reference position together.
Then, if signal (step S3) discharged by the sheet material obtaining first page sheet material S from image processing system 1, then think that first page sheet material S has been transported on post-processing dish 11, utilize FD align unit 14 to carry out FD alignment (step S4), utilize CD alignment plate 13 to carry out CD alignment (step S5) (Fig. 4).
The FD alignment utilizing FD align unit 14 to carry out is that the action by FD align unit 14 is moved to the FD aligned position suitable with the sheet length L based on sheet material information from reference position is carried out.
FD align unit 14 is predefined according to each sheet length to the miles of relative movement of FD aligned position from reference position.The movement of FD align unit 14 is by rotating forward to be equivalent to reference position drive the FD motor M3 that aligns to carry out to the align rotation number of motor M3 or angle of rotation of the FD of miles of relative movement of the FD aligned position corresponding to sheet length L.
The CD alignment utilizing CD alignment plate 13 to carry out is that the action by CD alignment plate 13 is moved to the CD aligned position suitable with the sheet width W based on sheet material information from reference position is carried out.
CD alignment plate 13 is pre-determined by each sheet width W from reference position to the miles of relative movement of CD aligned position.The movement of CD alignment plate 13 is by rotating forward to be equivalent to reference position drive the CD motor M2 that aligns to carry out to the align rotation number of motor M2 or angle of rotation of the CD of the miles of relative movement of the CD aligned position corresponding with sheet width W.
The number of pages (sheet material number of pages) judging the sheet material S discharged by image processing system 1 whether with number of pages (bookbinding number of pages) N equal (step S6) of the sheet material S that should bind.
If judge sheet material number of pages and bookbinding number of pages N unequal (as "No" in step S6), then the action (step S7) returning predetermined distance (being 10mm above-mentioned example) from its aligned position to reference position side is all carried out to FD align unit 14 and CD alignment plate 13 both sides, wait for that ensuing second page sheet material S is admitted to.
The action making FD align unit 14 and CD alignment plate 13 return predetermined distance to reference position side is reversed driven FD motor M3 and the CD motor M2 that aligns that aligns to carry out by the align rotation number of motor M2 or angle of rotation of motor M3 and the CD that aligns with the FD being equivalent to predetermined distance.
If signal (step S3) discharged by the sheet material obtaining second page sheet material S from image processing system 1, then by the process of step S4, S5, first page sheet material S is alignd with the second page sheet material S loaded thereon, then shifts to step S6.
If judge sheet material number of pages and bookbinding number of pages N unequal (as "No" in step S6), then again carry out the process of step S7, S3 ~ S6.Repeat the process of step S3 ~ S7, until judge that sheet material number of pages is equal with bookbinding number of pages N.
If judge sheet material number of pages and bookbinding number of pages N equal (as "Yes" in step S6), then carry out FD align unit 14 is back to reference position action (step S8) (Fig. 5).
The action that FD align unit 14 is back to reference position drives FD alignment motor M3 by reversion, when reference position detecting sensor 33 detects FD align unit 14, stops FD alignment motor M3 to carry out.
Then, mobile FD transfer unit 15, by the sheet bundle Sb on post-processing dish 11 to gutter pos conveying (step S9) (Fig. 6).
Sheet bundle Sb is rotated forward by the rotation number of the conveying motor M1 to be equivalent to the fed distance determined according to above-mentioned gutter pos information or angle of rotation to drive conveying motor M1 to the conveying of this gutter pos, makes FD transfer unit 15 move to carry out.
When sheet bundle Sb is delivered to gutter pos, binder mechanism 103 couples of sheet bundle Sb are utilized to bind (step S10).
After sheet bundle Sb is bound, and then mobile FD transfer unit 15, the sheet material Sb after bookbinding is carried (step S11) (Fig. 7) to the transmitting place of device face side.
Sheet bundle Sb is drive conveying motor M1 by rotating forward with the rotation number of the conveying motor M1 of the fed distance till the transmitting place being equivalent to sheet bundle Sb or angle of rotation to the conveying of transmitting place, makes FD transfer unit 15 move to carry out.Fed distance till the transmitting place of sheet material Sb is determined according to the size of above-mentioned distance (L2-L1).
Then, pawl 16 will be guided, 17 from the Posture exchange that submerges for outstanding attitude (step S12) (Fig. 8).This switching guides pawl to drive actuating mechanism 36 to carry out by driving.
When guiding pawl 16,17 is from the finishing switching of attitude to outstanding attitude of submerging, carry out making FD transfer unit 15 be back to the action (step S13) of reference position.
The action making FD transfer unit 15 be back to reference position drives conveying motor M1 by reversion, when FD transfer unit 15 being detected by reference position detecting sensor 34, stops conveying motor M1 to carry out.
Then, carry out making CD alignment plate 13 be back to the action (step S14) of reference position.
The action making CD alignment plate 13 be back to reference position drives CD alignment motor M2 by reversion, when CD alignment plate 13 being detected by reference position detecting sensor 32, stops CD alignment motor M2 to carry out.
Then, in the step S15 shown in Figure 14, wobble-plate 22 is raised, make it to transit to horizontal attitude (Fig. 9) from lateral attitude.
Wobble-plate 22 is rotate forward to drive by the rotation number of the regulation wobble-plate 22 to be changed the lifting motor M5 required for attitude to horizontal attitude from lateral attitude or angle of rotation to promote motor M5 and carry out from lateral attitude to the transition of horizontal attitude.
Judge whether to be in and utilize four pressing jaw 52 being arranged at standing wall portion 51b to keep (step S16) in the action of sheet bundle Sb.What utilize pressing jaw 53 couples of sheet bundle Sb to carry out is maintained by step S20 described later to carry out.
At this, be judged as not being in (being "No" in step S16) in the action of maintenance sheet bundle, thus CD datum plate 12 is moved from device back side lateral device face side, will the sheet bundle Sb of wobble-plate 22 be placed in device face side transfer (step S18) (Figure 10).The transfer of sheet bundle Sb drives transfer motor M4 to carry out by rotating forward.
CD datum plate 12 is by rotate forward from the reference position of device rear side to the rotation number of the transfer motor M4 of the predetermined distance of device face side assigned position foremost or angle of rotation drive transfer motor M4 to carry out to be equivalent to CD datum plate 12 from the movement of device back side lateral device face side.
If CD datum plate 12 moves to device face side foremost, sheet bundle Sb terminates (being "Yes" in step S19) to the transfer of device face side, then think and sheet bundle Sb has been accommodated in positive face 51, carry out by four pressing jaw 52 action (step S20) (Figure 11) of keeping sheet bundle Sb.The action of sheet bundle Sb is kept to drive actuating mechanism 37 to carry out by driving pressing jaw by pressing jaw 52.
Then, CD datum plate 12 is moved from device front lateral device rear side, carry out the action (step S21) being back to reference position.The action making CD datum plate 12 be back to reference position drives transfer motor M4 by reversion, when CD datum plate 12 being detected by reference position detecting sensor 31, stops transfer motor M4 to carry out.
If CD datum plate 12 is back to reference position, then make wobble-plate 22 decline, transit to lateral attitude (step S22) from horizontal attitude.
Wobble-plate 22 is driven by reversion to promote motor M5 from horizontal attitude to the transition of lateral attitude, when detecting that wobble-plate 22 has been back to lateral attitude by reference position detecting sensor 35, stops lifting motor M5 to carry out.
Then, guiding pawl 16,17 is made to revert to attitude of submerging (step S23).Transition to this attitude of submerging drives the driving of actuating mechanism 36 to carry out by stopping guiding pawl.
Then, judge whether task terminates (step S24).If the task of being judged as does not terminate (being "No" in step S24), then in order to carry out the bookbinding to second sheet bundle Sb, being back to the step S2 shown in Figure 13, carrying out the process after step S2.
After the bookbinding of second sheet bundle Sb is terminated (step S10), when wobble-plate 22 transits to horizontal attitude (step S15), judge whether to be in and utilize four pressing jaw 52 to keep (step S16) in the action of sheet bundle Sb.At this, because be in the action (above-mentioned steps S20) continuing maintenance first sheet bundle Sb, so be judged as being in (being "Yes" in step S16) in action, remove the maintenance (step S17) utilizing pressing jaw 52 couples of sheet bundle Sb.This releasing is that thus, pressing jaw 52 reverts to position of submerging by stopping pressing jaw driving the driving of actuating mechanism 37 to carry out.
If remove the maintenance to sheet bundle Sb utilizing pressing jaw 52, then make second the sheet bundle Sb be placed on wobble-plate 22 transfer to device face side, be accommodated in positive face 51 (step S18).
Thus, second sheet bundle Sb, being loaded under the state on first the sheet bundle Sb being accommodated in positive face 51, is incorporated on positive face 51.Under the state that second sheet bundle Sb is loaded on first sheet bundle Sb, pressing jaw 51 is again utilized to keep sheet bundle Sb (step S20).
In step s 24 which, if be judged as that task does not terminate, also have the bookbinding (being "No" in step S24) to the 3rd sheet bundle Sb, be then again back to step S2, carry out the process of step S2 ~ S24.
Each portion number is carried out repeatedly to the process of step S2 ~ S24, until be judged as that task terminates, if terminated to the transfer of device face side the sheet bundle Sb after the bookbinding of all portions number, then be judged as that task terminates (being "Yes" in step S24), after the maintenance (step S25) removing pressing jaw 52 couples of sheet bundle Sb, terminate this control.
Above, although the description of the example carried out sheet bundle Sb in bookbinding situation, but such as when not binding, the process of step S9 and S10 is not carried out.And, only under one page sheet material S instead of the task situation that prints sheet bundle Sb, after each process only carrying out step S3, S11, S12, S13, S15, S18, S19, S21, S22 successively, terminate this control.
