As a result, in the present embodiment, the opening 89 (see FIG. 3) located between the advance body 300 and the cover member 480 is closed even after the advance body 300 has advanced.
In addition, in the present embodiment, the regulating member 90 is arranged so as to straddle the gap G1 (see FIG. 3) and the gap G2 even if the advance body 300 advances, and even if the advance body 300 advances, the gap G1 , The entry of the paper P into the gap G2 is suppressed.

Further, in the present embodiment, as shown in FIG. 6B, the inclined portion 90B (a part of the regulating member 90) of the regulating member 90 is on the right side of the drawing when the advancing body 300 is advanced to the paper loading portion 60. As the paper loading unit 60 advances in the direction, the paper stack 60 is arranged in an inclined state so as to gradually move away from the paper bundle T.

More specifically, in the present embodiment, the movable roll 62 is attached to the advance body 300, and the advance body 300 moves the paper P of the paper loading unit 60 in one direction (the direction indicated by the arrow 6C in the drawing). It has a function to send out.
In the present embodiment, in the state where the advancing body 300 advances to the paper loading portion 60 (in the state shown in FIG. 6B), the downstream side portion (the portion of the inclined portion 90B) of the regulating member 90 in this one direction. ) Is inclined so as to gradually move away from the paper bundle T of the paper loading unit 60 as it advances to the downstream side in this one direction. In other words, this downstream portion is arranged in an inclined state with respect to this one direction.

As a result, in the present embodiment, as the paper is advanced to the downstream side in one direction, the paper P can be fed out more smoothly by the advancing body 300 as compared with the case where the regulating member 90 approaches the paper bundle T of the paper loading unit 60.
Here, when the regulating member 90 approaches the paper bundle T as it advances to the downstream side in one direction, the paper bundle T comes into contact with the regulating member 90 when the paper bundle T is moved to the stacker 80 (see FIG. 2). However, the paper bundle T may be difficult to move.

Further, when the regulating member 90 approaches the paper bundle T as it advances to the downstream side in one direction, the regulating member 90 comes into contact with the paper bundle T when the advancing body 300 advances to the paper loading unit 60. There is a possibility that the position of the paper P included in the paper bundle T may be displaced.
In addition, in the present embodiment, every time a new paper P is supplied to the paper loading unit 60, the advance body 300 is advanced to the paper loading unit 60 (details will be described later), but at this time, the paper bundle T is used. On the other hand, when the regulating member 90 comes into contact with the paper bundle T, the position of the paper P included in the paper bundle T may be displaced.
On the other hand, when the regulating member 90 is warped as in the present embodiment, the regulating member 90 is suppressed from coming into contact with the paper P when the advancing body 300 advances to the paper loading unit 60, and the paper P is prevented from coming into contact with the paper P. Misalignment is suppressed.

In the above description, the configuration in which the regulation member 90 is attached to the advance body 300 has been described as an example. In other words, the configuration in which the regulating member 90 is attached to the advancing body 300, which is a moving body, has been described as an example. By the way, the attachment destination of the regulation member 90 is not limited to the advance body 300, and may be the main body side of the recording material processing device 2.
Specifically, for example, as shown in FIG. 7 (a diagram showing another configuration example of the recording material processing device 2, the regulation member 90 may be attached to the cover member 480.

In this case, when the second paddle 692 advances to the paper loading section 60, the regulating member 90 is deformed as shown by the broken line.
Also in this case, the movement of the end YT of the paper P that is about to be lifted by the second paddle 692 is restricted by the regulating member 90. Also in this case, the end portion YT of the paper P enters the gap G1 located between the advance body 300 and the second paddle 692 and the gap G2 located between the cover member 480 and the second paddle 692. Is suppressed.

8 (A), (B), and (C) are diagrams for explaining the movement of the movable roll 62.
In the present embodiment, as described above, when the paper bundle T is moved to the stacker 80, the movable roll 62 is advanced toward the paper loading unit 60.
Further, in the present embodiment, each time a new paper P is supplied to the paper loading unit 60, the movable roll 62 is advanced toward the paper loading unit 60. More specifically, each time a new supply is made to the paper loading unit 60, the movable roll 62 advances to the paper loading unit 60 and the movable roll 62 is retracted from the paper loading unit 60.

FIG. 8A shows the states of the movable roll 62, the second paddle 692, and the like when the rear end of the paper P is detected by the paper detection sensor S.
In the present embodiment, as shown in FIG. 8A, when the rear end of the newly supplied paper P is detected by the paper detection sensor S, the second paddle 692 advances toward the paper loading unit 60. To do.
When the second paddle 692 advances toward the paper loading section 60, the second paddle 692 comes into contact with the newly supplied paper P, and the paper P is urged toward the end guide 64. ..

Here, in the present embodiment, as described above, when the second paddle 692 is advanced, the second paddle 692 comes into contact with the end YT of the paper P, and this end YT becomes the second paddle. May be lifted by 692.
Then, in this case, as described above, the end portion YT may enter the gap G1 (see FIG. 3) or the gap G2.

Therefore, in the present embodiment, as shown by the arrow 8A in FIG. 8A, the movable roll 62 (advancing body 300) is advanced toward the paper loading unit 60.
In addition, in the present embodiment, in addition to providing the regulating member 90 as described above, the movable roll 62 is advanced toward the paper loading unit 60.

More specifically, in the present embodiment, the advancing / retreating mechanism 310 (see FIG. 3) is driven and movable after a predetermined time has elapsed after the rear end of the paper P is detected by the paper detection sensor S. The roll 62 is advanced toward the paper loading unit 60.
More specifically, in the present embodiment, after starting the evacuation of the second paddle 692 advanced to the paper loading unit 60, the movable roll 62 is started to advance to the paper loading unit 60.

More specifically, in the present embodiment, the movable roll 62 is retracted from the paper loading unit 60 before the new paper P is supplied to the paper loading unit 60, but the new paper P is retracted from the paper loading unit 60. After being supplied to the 60, the movable roll 62 advances toward the paper loading unit 60.

Here, if the movable roll 62 is advanced before starting the evacuation of the second paddle 692, the paper P to be moved toward the end guide 64 using the second paddle 692 is the movable roll 62. It may be difficult to move due to contact with.
Therefore, in the present embodiment, after the second paddle 692 is retracted from the paper loading unit 60, the movable roll 62 is started to advance to the paper loading unit 60.

If the paper P supplied to the paper loading unit 60 is larger than a predetermined size, a process may be performed in which the movable roll 62 does not advance.
This is because when the size of the paper P is larger than the predetermined size, the second paddle 692 does not come into contact with the end YT of the paper P, and the paper P does not float.

Here, when the movable roll 62 is advanced even when the size of the paper P is large, the movable roll 62 is advanced even though it is not necessary, and the movable roll is moved closer to the movement path of the paper P. 62 will be located. In such a case, the possibility that the supplied paper P comes into contact with the movable roll 62 increases, and the possibility that the movement of the paper P is restricted increases.
On the other hand, in the case of the configuration in which the movable roll 62 is not moved, unnecessary contact of the paper P with the movable roll 62 is avoided, and the paper P can be moved more smoothly.

FIG. 8B shows a state after the movable roll 62 is advanced to the paper loading unit 60.
When the movable roll 62 advances to the paper loading unit 60, the movable roll 62 approaches the paper bundle T of the paper loading unit 60. As a result, the movement of the paper P that is about to float is restricted.

Here, in the present embodiment, as shown in FIG. 8B, the movable roll 62 sandwiches the paper bundle T resting on the paper support surface 67A included in the support member 67, and the position of the movable roll 62 facing the paper support surface 67A. Placed in.
In the present embodiment, when the movable roll 62 advances to the paper loading portion 60, the movable roll 62 advances toward the paper support surface 67A and is arranged to face one surface of the paper P on the paper support surface 67A. .. As a result, the paper P to be lifted comes into contact with the movable roll 62, and its movement is restricted.

More specifically, in the present embodiment, when the second paddle 692 comes into contact with the end YT of the paper P, the end YT is displaced in the thickness direction of the paper P.
At this time, in the present embodiment, the movable roll 62 as an example of the holding member is located at the position facing the end YT, and the displacement of the end YT (mutation in the thickness direction of the paper P) is suppressed. Be done.

FIG. 8C is a diagram showing the state of the movable roll 62 and the second paddle 692 when the new paper P is further conveyed.
In the present embodiment, when the paper P is newly conveyed from the upstream side, the tip end portion of the paper P is detected by the paper detection sensor S. Then, in this case, in the present embodiment, as shown by the arrow 8C, the movable roll 62 retracts upward.
As a result, the contact of the new paper P with the movable roll 62 is suppressed, and the movement of the new paper P is suppressed from being restricted by the movable roll 62.

After that, in the present embodiment, new paper is sequentially supplied to the paper loading unit 60. Then, when a predetermined number of sheets of paper P are loaded on the paper loading unit 60 (when a paper bundle T is generated), the binding process is performed by the binding unit 51 (see FIG. 2).
After that, in the present embodiment, the movable roll 62 advances again toward the paper loading unit 60, and the paper bundle T is sandwiched between the movable roll 62 and the transport roll 61. Then, the movable roll 62 and the conveying roll 61 rotate, and the paper bundle T is conveyed to the stacker 80.

In the process described above, as shown in FIG. 8B, when the movable roll 62 is advanced toward the paper loading unit 60, the movable roll 62 is not pressed against the paper bundle T. The movable roll 62 may be advanced more and the movable roll 62 may be pressed against the paper bundle T of the paper loading unit 60.
In this case, the swelling of the paper bundle T of the paper loading unit 60 can be reduced as compared with the case where the movable roll 62 is not pressed against the paper bundle T.

Here, in the present embodiment, the moving / retreating of the movable roll 62 is performed by using a stepping motor, and the position of the movable roll 62 can be adjusted (the amount of advancing / retreating of the movable roll 62 can be adjusted).
If the movable roll 62 is advanced to a position closer to the paper loading unit 60, the movable roll 62 is pressed against the paper bundle T as described above.

Further, in the above, the movable roll 62 is used to suppress the displacement of the paper P of the paper loading unit 60 (displacement of the paper P in the thickness direction), but a dedicated member for suppressing the displacement is installed. The displacement of the paper P may be suppressed.
Further, in the above, the movable roll 62 is moved forward and backward each time the paper P is conveyed to the paper loading unit 60, but when the first sheet P constituting the paper bundle T is conveyed. The movable roll 62 may be advanced and the movable roll 62 may be kept advanced until the last paper P constituting the paper bundle T is conveyed.

Further, the advance position of the movable roll 62 may be changed according to the number of sheets P constituting the paper bundle T.
Specifically, for example, when the number of sheets P constituting the bundle T is less than a predetermined number, the movable roll 62 is advanced to the first position, and the number of sheets P constituting the bundle T is reached. When the number of sheets is equal to or more than the predetermined number of sheets, the movable roll 62 may be advanced to a second position farther from the paper loading unit 60 than the first position.

Further, as new paper P is supplied to the paper loading unit 60, the advance position of the movable roll 62 may be gradually separated from the paper loading unit 60.
Specifically, when the number of sheets of paper P loaded on the paper loading unit 60 is less than the predetermined number of sheets, the movable roll 62 is advanced to the first position, and the number of sheets of paper P loaded gradually increases. When the number of sheets of paper P loaded on the paper loading unit 60 exceeds a predetermined number, the movable roll 62 moves to a second position away from the paper loading unit 60 from this first position. May be advanced.

(Other)
The lifting of the paper P caused by the contact of the second paddle 692 with the end portion YT of the paper bundle T is also caused by the configuration example shown in FIG. 9 (a diagram showing another configuration example of the recording material processing device 2). Occurrence can be suppressed.
In the configuration example shown in FIG. 9, the end guide 64 is moved so as to approach the second paddle 692, and the loading location of the paper P is shifted to the second paddle 692 side.
Specifically, in this configuration example, when the size of the paper P is smaller than the predetermined size, the end guide 64 is moved so as to approach the second paddle 692, and the loading location of the paper P is set to the second paddle. It is shifted to the 692 side.

As a result, the position where the paper bundle T is generated shifts to the side of the second paddle 692, and the end portion YT of the paper bundle T is located at a position deviated from directly below the second paddle 692. Then, in this case, the contact of the second paddle 692 with the end portion YT of the paper bundle T is avoided, and the floating of the paper P is suppressed.
In this configuration example, the end guide 64 is moved to move the loading location of the paper P, but another member different from the end guide 64 may be moved to move the loading location of the paper P. Good.

Further, in the image forming system 500 of the present embodiment, as shown in FIGS. 1 and 2, the recording material processing device 2 provided with the binding mechanism and the drilling mechanism has been described as an example, but the recording material processing device 2 has a description. In addition, a folding mechanism and a mechanical part such as a booklet making part may be installed.
