The state that distributing roller 29a is crimped onto on trip roller 29b by the deadweight of roller rest support frame 31 clamps paper P.
Also, at the end of the paper P of pile reception, binding unit 40 is moved to location division 30a gap position, will
The rear end insertion bookbinding bail portion 40a of paper stack, the binding process of paper stack is carried out by bookbinding bail portion 40a.By bookbinding bail portion 40a
After the binding process for carrying out paper stack, by making the positive rotation of the second discharge roller pair 29 (Fig. 3 direction of arrow), paper stack edge processing disk 30
Conveying upward, is discharged in discharge tray 50.When paper stack is discharged in discharge tray 50, be not only roller support frame 31 from
Weight, is also exerted a force downwards to roller support frame 31 by force application components such as springs, distributing roller 29a is crimped with trip roller 29b.By
This, due to clamp paper stack than pulling in power strong during paper P, paper stack can be reliably discharged to discharge tray 50.
In addition, in the case where indicating displacement discharge, when the second discharge roller pair 29 of driving is to the discharge paper stack of discharge tray 50,
First, roller support frame 31 is moved to retreating position.Then, side is adjusted into the position (mark that vernier 60 is configured to reception paper P
Level is put), or (moved from normal place to the position of the mobile ormal weight in the direction (paper width direction) vertical with discharge direction
Position position).Also, roller support frame 31 is moved to abutted position, paper is discharged.Thus, paper stack is alternately discharged to discharge tray 50
On benchmark drain position and the mobile regulation from benchmark drain position to the direction (paper width direction) vertical with discharge direction
The displacement drain position of amount, each paper stack is separated from each other heap when being discharged in discharge tray 50 (reference picture 2) on paper width direction
Put and classify.
In the sheet post-process apparatus 20 of present embodiment, the trip roller of the second discharge roller pair of composition 29 can be made
29b only rotates to the positive direction (Fig. 2,3 rotate counterclockwise direction) being discharged to paper P in discharge tray 50.
By this composition, as shown in figure 4, when being pulled paper P2 using the second discharge roller pair 29 on processing disk 30,
In the state of trip roller 29b rotation stopping is made, only make distributing roller 29a reverse rotations.As a result, pull-in forces are acted only on newly
The paper P2 of input, the adjusted paper stack P1 for the location division 30a for having encountered processing disk 30 is not acted on.Therefore, it is not necessary to carry on a shoulder pole
Insides pile P1 is drawn into and warpage together with paper P2, can effectively prevent from handling the drop of the scalability of the paper stack on disk 30
It is low.
As that can make the method for trip roller 29b only positive rotations, can enumerate such as assembling can make trip roller 29b
The rotary shaft only one-way mechanism such as the ratchet that is rotated to a direction or one-way clutch method.
In addition, by enabling support distributing roller 29a roller support frame 31 to swing, distributing roller 29a configuration can be held
Easily between leaving trip roller 29b position (retreating position) and abutting to the position on trip roller 29b (abutted position)
Switching.
In addition, the invention is not restricted to above-mentioned embodiment, can carry out without departing from the scope of the subject in the invention various
Change.For example, in said embodiment, to be directly connected to the structure of image processing system 100 and sheet post-process apparatus 20
Exemplified by be illustrated, but be mounted between image processing system 100 and sheet post-process apparatus 20 insertion interleaving paper
The mechanism of flush mounting also can be using the present invention.
The present invention can be used in adjusting and stacking on a process disk using discharge roller pair the sheet post processing dress of sheet
Put.By using the present invention, using the teaching of the invention it is possible to provide can prevent when sheet adjustment sheet pile is pulled on from discharge roller pair to processing disk
Only the bad sheet post of the adjustment of sheet pile and the image for possessing the sheet post form system
System.
