In this bookbinding is handled, binding apparatus ST1 is moved to the position in the bight that thin slice piles up, isolated equally spacedly two positions, mind-set both sides from sheet width, or a plurality of positions that are fit to.
(holding the explanation of action)
Describe holding action below by Fig. 5, Figure 14 and Figure 20.At first, by shown in the image pattern 5 like that, to from the sheet width center of accumulation dish 29 to two positions of both sides equal spacings, be provided with guide part G40, G50 structure occasion and describe.At first, handle in the bookbinding that formerly illustrates, the supporting mass G70 that is mounted with binding apparatus ST1 and clamping device G10 is positioned the state of the state of Fig. 5, by not shown driving motor, the cross section is the state of the S. A. G2 of square from Figure 14, is rotated in a clockwise direction.The 1st gear G86 that receives this rotation is rotated in a clockwise direction thereupon.The 2nd gear G85 rotates in the counterclockwise direction with the 1st gear G86 ingear, and fan-shaped gear G84 is rotated in a clockwise direction.Be rotated in a clockwise direction with this fan-shaped gear G84 all-in-one-piece reciprocally swinging bar G81.
Receive this reciprocally swinging bar G81 torque along clockwise direction, shown in the image pattern 15 like that, move with the adapter shaft G15 of the chimeric holding part G11～G20 of the slit G82 of reciprocally swinging bar G81, follow moving of this adapter shaft G15, oscillating axle G12 and the buckle slot G80c of supporting support body G80 break away from, thus, top holding part G 11 holds thin slice and piles up with bottom holding part G16.At this moment, by facade,, fitly hold under the situation that can stagger at the uppermost paper in thin slice not being piled up while push the side end mode that thin slice is piled up of holding by bottom holding part G16.
In addition, reciprocally swinging bar G81 rotates to position shown in Figure 16, thus, holds top holding part G11 that thin slice piles up and bottom holding part G16 at outstanding state above the ejection port of row's paper disc 21, discharges thin slice and piles up.At this state, the swing arm G35 of holding part G11～G20 is at the sidewall of supporting support body G80, be offset to the paper lower left at ordinary times by extension spring G87, with can contact along the bias axis G89 that slit G88 supports with moving freely, rotation forcibly along clockwise direction, thus, holding part G11～G20 with swing arm G20 be the center and along clockwise direction forcibly the swing.

The control part of Gou Chenging carries out following processing action at sheet post processing apparatus B as described above.
(printing output mode)
In this mode, device for image forming A from such as, the 1st page is carried out image to a series of text and forms, and sends according to ventricumbent mode successively from main body ejection port 3.Here, the buffer-oriented spare 26 that sheet post processing apparatus B sends thin slice into path P1 falls back on the top of Fig. 3, path transfer strip 27 is moved to the state of the solid line of Fig. 3.Thus, send sending into thin slice into the thin slice guiding exit roller 25 of path P1.So, by the signal that detects the thin slice front end by row's paper 25a, after the thin slice front end arrived estimated time of positive and negative transfer roller 30 of accumulation thin slice 29, thin slice transported control part 64a positive and negative transfer roller 30 is dropped on the dish from the top holding fix, made this positive and negative transfer roller rotation along the clockwise direction of Fig. 4.So the thin slice that enters on the accumulation dish 29 passes through this positive and negative transfer roller 30, send towards the 1st row's paper disc 21, be received on this dish.With follow-up like this successively thin slice pass out to the 1st row paper disc 21, the accumulation and be received on this dish.
So, in this printing output mode, carried out the thin slice of image forming by device for image forming A and sent into path P1 through the thin slice of sheet post processing apparatus B, be received in the 1st row's paper disc 21, such as, with ventricumbent posture, from the 1st page of order of n page or leaf successively, accumulation being received in the top.In this pattern, above-mentioned the 1st change of direction conveying channel SP1 and the 2nd change of direction conveying channel (thin slice processing path) SP2 does not lead thin slice.
(binding final tupe)
In the occasion of this pattern, device for image forming A is identical with above-mentioned printing output mode, from the 1st page of order according to the n page or leaf, a series of text is carried out image forming, at ventricumbent state, sends from main body ejection port 3.So sheet post processing apparatus B is with formerly pattern is identical, the buffer-oriented spare 26 that thin slice is sent into path P1 returns to the upper side of Fig. 3, path transfer strip 27 is moved to the state of the solid line of Fig. 3.Thus, the thin slice guiding exit roller 25 that thin slice is sent into path P1 will be given.Here, at the signal that passes through to detect the thin slice front end by ejection port 25a, after the estimated time of the positive and negative transfer roller 30 of thin slice front end arrival accumulation dish 29, thin slice transports control part 64a positive and negative transfer roller 30 is dropped on the dish from the top holding fix, makes this positive and negative transfer roller rotation along the clockwise direction of Fig. 4.Then, thin slice transports control part 64a after estimated time on the accumulation dish 29 is sent in the thin slice rear end, drives positive and negative transfer roller 30 along the anticlockwise direction rotation of Fig. 3.So the thin slice that enters from ejection port 25a is along the 1st change of direction conveying channel SP1, change of direction is transported on the accumulation dish 29.By carrying out transporting of this thin slice repeatedly, a series of thin slice is pile shape and accumulates on the accumulation dish 29 at ventricumbent state.
In addition, when the accumulation of the thin slice on above-mentioned accumulation dish 29, Controlled CPU 61 makes side alignment plate 34b action, and the width position of the thin slice accumulated is alignd.Then, Controlled CPU 61 makes end face binding apparatus ST1 action by the end of job signal from device for image forming A, and the end edge that the thin slice that accumulates on the accumulation dish 29 is piled up is bound.After this bookbinding action, Controlled CPU 61 is piled up the solid line position of the rear end limiting part 32 of delivering mechanism from Fig. 3 with double as, is displaced into the dotted line position of Fig. 3.So, through the bookbinding thin slice pile up send be received in the 1st row paper disc 21 on.Thus, a series of thin slice that has carried out image forming by device for image forming A is bound, it is received in the 1st row's paper disc 21.
(thin slice is piled up folding final tupe)
In this pattern, device for image forming A, is this shape and finally handles by sheet post processing apparatus B according to such as, Fig. 5 and the order that illustrates is carried out image forming on thin slice.For this reason, the buffer-oriented spare 26 that sheet post processing apparatus B sends thin slice into path P1 falls back on the top of Fig. 3, path transfer strip 27 is moved to the state of the solid line of Fig. 3.Thus, send delivering to thin slice into the thin slice guiding exit roller 25 of path P1.So Controlled CPU 61 is a benchmark with the signal that detects the thin slice rear end by thin slice sensor S1, by the moment of path transfer strip 27, stop exit roller 25 in the thin slice rear end, simultaneously path transfer strip 27 is moved to the dotted line position of Fig. 3.Then, with exit roller 25 counter-rotatings (anticlockwise direction of Fig. 3).So, enter the carriage direction counter-rotating that thin slice is sent into the thin slice among the path P1, from path transfer strip 27 leads thin slice thin slice inlet passage 35a.Then, transport roller 36,37 by being arranged in this path, with this thin slice guided bend guide part 35b.
