Abstract

A post-processing device includes a stacking portion on which media are stacked; a staple binding device that binds the media together by using a staple and that is movable between staple binding positions at which the staple binding device binds the media together and a supply position that is in a front section in a width direction of the media and at which staples are suppliable to the staple binding device; and a stapleless binding device that binds the media together without using a staple and that is movable between a stapleless binding position at which the stapleless binding device binds the media together and a retracted position that is in the front section. When the stapleless binding device is moved to the retracted position, the staple binding device and the stapleless binding device do not interfere with each other irrespective of a position of the staple binding device.

First claim

What is claimed is:

1. A post-processing device comprising:
a stacking portion on which media having images recorded thereon are stacked;
a staple binding device that binds the media stacked on the stacking portion together by using a staple and that is movable between a plurality of staple binding positions at which the staple binding device binds the media together and a supply position that is in a front section in a width direction of the media and at which staples are suppliable to the staple binding device; and
a stapleless binding device that binds the media stacked on the stacking portion together without using a staple and that is movable between a stapleless binding position at which the stapleless binding device binds the media together and a retracted position that is in the front section in the width direction of the media,
wherein, when the stapleless binding device is moved to the retracted position, the staple binding device and the stapleless binding device do not interfere with each other irrespective of a position of the staple binding device.

2. The post-processing device according to claim 1 , wherein the stapleless binding position, at which the stapleless binding device binds the media together without using a staple, is at or behind the supply position of the staple binding device, which binds the media together by using a staple, in the width direction of the media.

3. The post-processing device according to claim 1 , wherein one of the staple binding positions that is foremost in the width direction of the media coincides with the stapleless binding position, at which the stapleless binding device binds the media together without using a staple.

4. The post-processing device according to claim 1 , wherein the stapleless binding device is capable of performing stapleless binding on media inserted from outside of the post-processing device at the retracted position.

5. The post-processing device according to claim 4 , further comprising:
an input member used to perform stapleless binding at the retracted position.

6. The post-processing device according to claim 4 , further comprising:
a window through which the stapleless binding device moved to the retracted position is externally visible.

7. The post-processing device according to claim 1 , wherein the stapleless binding device rotates around a rotation center to move between the stapleless binding position and the retracted position.

8. The post-processing device according to claim 7 , further comprising:
a first gear supported by a body of the post-processing device; and
a second gear that meshes with the first gear and that is supported by the stapleless binding device, the second gear moving the stapleless binding device between the stapleless binding position and the retracted position as the first gear rotates.

9. The post-processing device according to claim 7 , further comprising:
a support that supports the stapleless binding device so that the stapleless binding device is rotatable, that is supported by a body of the post-processing device so as to be rotatable around the rotation center, and that moves the stapleless binding device between the stapleless binding position and the retracted position.

10. The post-processing device according to claim 1 , wherein when the staple binding device moves to the supply position, the stapleless binding device moves to the retracted position in response to a movement of the staple binding device.

11. An image forming apparatus comprising:
an image forming apparatus body that forms images on media; and
the post-processing device according to claim 1 that performs post-processing on the media transported from the image recording apparatus body.
