Abstract

A recording medium processing apparatus includes first teeth that are used for binding processing of a recording medium bundle; second teeth that move toward the first teeth and press the recording medium bundle located between the first teeth and the second teeth; and a control unit that moves the second teeth toward the first teeth to press the second teeth against the first teeth in a state in which there is no recording medium bundle between the first teeth and the second teeth.

First claim

What is claimed is:

1. A recording medium processing apparatus comprising:
first teeth that are used for binding processing of a recording medium bundle;
second teeth that move toward the first teeth and press the recording medium bundle located between the first teeth and the second teeth,
a control unit that moves the second teeth toward the first teeth to press the second teeth against the first teeth in a state in which there is no recording medium bundle between the first teeth and the second teeth, and
a movement amount acquisition unit that acquires a movement amount of the second teeth in a case where the control unit presses the second teeth against the first teeth.

2. The recording medium processing apparatus according to claim 1 ,
wherein the control unit moves the second teeth to the first teeth to press the second teeth against the first teeth at a timing between a timing at which binding processing for one recording medium bundle is performed and a timing at which binding processing for another recording medium bundle is performed.

3. The recording medium processing apparatus according to claim 1 ,
wherein a frequency with which the control unit presses the second teeth against the first teeth changes.

4. The recording medium processing apparatus according to claim 3 ,
wherein the frequency with which the control unit presses the second teeth against the first teeth changes depending on a content of processing in the recording medium processing apparatus.

5. The recording medium processing apparatus according to claim 3 ,
wherein the frequency with which the control unit presses the second teeth against the first teeth changes depending on the number of times of the binding processing in the recording medium processing apparatus.

6. The recording medium processing apparatus according to claim 5 ,
wherein the frequency with which the control unit presses the second teeth against the first teeth decreases depending on an increase in the number of times of the binding processing in the recording medium processing apparatus.

7. The recording medium processing apparatus according to claim 1 , further comprising:
an information change unit that changes setting information that is information set for the second teeth on the basis of the movement amount acquired by the movement amount acquisition unit.

8. The recording medium processing apparatus according to claim 7 ,
wherein the information change unit changes the setting information that is set for the second teeth and affects the movement amount of the second teeth.

9. The recording medium processing apparatus according to claim 7 ,
wherein the information change unit changes the setting information on the movement amount in a case where the second teeth moves toward the recording medium bundle to change the movement amount in a case where the second teeth moves toward the recording medium bundle, on the basis of the movement amount acquired by the movement amount acquisition unit.

10. The recording medium processing apparatus according to claim 9 ,
wherein the information change unit changes the setting information such that the movement amount in a case where the second teeth move toward the recording medium bundle becomes smaller in a case where the movement amount acquired by the movement amount acquisition unit is smaller than a predetermined value, and changes the setting information such that the movement amount in a case where the second teeth moves toward the recording medium bundle becomes larger in a case where the movement amount acquired by the movement amount acquisition unit is larger than the predetermined value.

11. The recording medium processing apparatus according to claim 1 ,
wherein the second teeth moves toward the recording medium bundle from a predetermined initial position in a case where the binding processing of the recording medium bundle is performed by the second teeth, and
the recording medium processing apparatus further comprising a position change unit is further provided to change the initial position on the basis of the movement amount acquired by the movement amount acquisition unit.

12. An image forming system comprising:
an image forming apparatus that forms an image on a recording medium; and
a recording medium processing apparatus that performs binding processing on a recording medium bundle including a plurality of sheets of recording mediums on which the image is formed by the image forming apparatus,
wherein the recording medium processing apparatus is constituted by the recording medium processing apparatus according to claim 1 .

13. An image foil ling system comprising:
an image forming apparatus that forms an image on a recording medium; and
a recording medium processing apparatus that performs binding processing on a recording medium bundle including a plurality of sheets of recording mediums on which an image is formed by the image forming apparatus,
wherein the recording medium processing apparatus is constituted by the recording medium processing apparatus according to claim 2 .

14. An image forming system comprising:
an image forming apparatus that forms an image on a recording medium; and
a recording medium processing apparatus that performs binding processing on a recording medium bundle including a plurality of sheets of recording mediums on which an image is formed by the image forming apparatus,
wherein the recording medium processing apparatus is constituted by the recording medium processing apparatus according to claim 3 .

15. An image forming system comprising:
an image forming apparatus that forms an image on a recording medium; and
a recording medium processing apparatus that performs binding processing on a recording medium bundle including a plurality of sheets of recording mediums on which an image is formed by the image forming apparatus,
wherein the recording medium processing apparatus is constituted by the recording medium processing apparatus according to claim 4 .

16. An image forming system comprising:
an image forming apparatus that forms an image on a recording medium; and
a recording medium processing apparatus that performs binding processing on a recording medium bundle including a plurality of sheets of recording mediums on which an image is formed by the image forming apparatus,
wherein the recording medium processing apparatus is constituted by the recording medium processing apparatus according to claim 5 .

17. An image forming system comprising:
an image forming apparatus that forms an image on a recording medium; and
a recording medium processing apparatus that performs binding processing on a recording medium bundle including a plurality of sheets of recording mediums on which an image is formed by the image forming apparatus,
wherein the recording medium processing apparatus is constituted by the recording medium processing apparatus according to claim 6 .

18. An image forming system comprising:
an image forming apparatus that forms an image on a recording medium; and
a recording medium processing apparatus that performs binding processing on a recording medium bundle including a plurality of sheets of recording mediums on which an image is formed by the image forming apparatus,
wherein the recording medium processing apparatus is constituted by the recording medium processing apparatus according to claim 1 .

19. An image forming system comprising:
an image forming apparatus that forms an image on a recording medium; and
a recor
