Manage disk 30.In this state, by making distributing roller 29a reverse rotation (direction of rotation counterclockwise of Fig. 3), paper P is along processing disk
30 are drawn into, and adjust rear end by positioning region 30a.Positioning region 30a is not formed continuously on entire paper width direction, portion
Ground is divided to be formed jagged.At this point, the top of paper P is in the state that is clamped by the second discharge roller pair 29, the front end of paper P is from the
Two discharge roller pairs 29 are prominent in discharge tray 50.When pulling paper P along processing disk 30, in order not to excessively pull in paper P, with only
Distributing roller 29a is crimped onto the clamping of the state on trip roller 29b paper P by the self weight of roller rest support frame 31.
Also, at the end of the reception of the paper P of a pile, binding unit 40 is moved to the gap position of positioning region 30a, it 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 29 positive rotation of the second discharge roller pair (arrow direction of Fig. 3), paper stack is along processing disk 30
Conveying upwards, is discharged in discharge tray 50.When paper stack is discharged in discharge tray 50, it is not only oneself of roller support frame 31
Weight also exerts a force downwards to roller support frame 31 by biasing members such as springs, crimps distributing roller 29a with trip roller 29b.By
This, strong power clamps paper stack when due to than pulling in paper P, and paper stack can be reliably discharged to discharge tray 50.
In addition, in the case where indicating displacement discharge, when paper stack is discharged to discharge tray 50 in the second discharge roller pair 29 of driving,
Firstly, roller support frame 31 is moved to retreating position.Then, side adjustment vernier 60 is configured to the position (mark for receiving paper P
Level is set), or (moved from normal place to the position of the mobile specified amount 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.Paper stack is alternately discharged to discharge tray 50 as a result,
On benchmark drain position and from benchmark drain position to the mobile regulation in the direction (paper width direction) vertical with discharge direction
The displacement drain position of amount, each paper stack are separated from each other heap when being discharged on discharge tray 50 (referring to Fig. 2) on paper width direction
It puts and classifies.
In the sheet post-process apparatus 20 of present embodiment, the trip roller for constituting the second discharge roller pair 29 can be made
29b is only to positive direction (Fig. 2, the 3 direction of rotation counterclockwise) rotation 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 stopping the rotation of trip roller 29b, only make distributing roller 29a reverse rotation.As a result, pull-in forces act only on newly
The paper P2 of input does not act on the adjusted paper stack P1 for having met the positioning region 30a of processing disk 30.Therefore, it is not necessary to carry on a shoulder pole
Insides pile P1 is drawn into and warpage together with paper P2, can be effectively prevented the drop of the scalability of the paper stack on processing disk 30
It is low.
As the method that can make trip roller 29b only positive rotation, can enumerate such as assembly can make trip roller 29b
Rotary shaft only one-way mechanisms such as the ratchet that is rotated to a direction or one-way clutch method.
In addition, the configuration of distributing roller 29a can be held by enabling the roller support frame 31 for supporting distributing roller 29a to swing
Easily in the position (retreating position) for leaving trip roller 29b and abut between the position on trip roller 29b (abutted position)
Switching.
In addition, the present invention is not limited to the above embodiments, 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 forming apparatus 100 and sheet post-process apparatus 20
For be illustrated, but be mounted between image forming apparatus 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
It sets.By using the present invention, it is capable of providing and is pulled in when sheet adjustment sheet is piled up and can be prevented on processing disk from discharge roller pair
Only the undesirable sheet post of adjustment of sheet pile and the image for having the sheet post form system
System.
