Abstract

A post-processing device includes first and second opposite members extending in a predetermined direction of a recording medium, the opposite members each including a first surface having a protrusion and a second surface having a recess, mutually facing to interpose the recording medium therebetween and being rotatable. A position of the opposite members is switched between a first position, at which the first surface of the first opposite member and the second surface of the second opposite member engage with each other and form a crease protruding in a first direction on the recording medium, and a second position, at which the second surface of the first opposite member and the first surface of the second opposite member engage with each other and form a crease protruding in a second direction reverse to the first direction on the recording medium, depending on an output destination of the recording medium.

First claim

What is claimed is:

1. A post-processing device, comprising:
a pair of first and second opposite members extending in a predetermined direction of a recording medium, each of the opposite members including a first surface having a protrusion and a second surface having a recess, the opposite members facing each other to interpose the recording medium therebetween and being rotatable,
wherein a position of the opposite members is switched between a first position, at which the first surface of the first opposite member and the second surface of the second opposite member engage with each other and form a crease protruding in a first direction on the recording medium, and a second position, at which the second surface of the first opposite member and the first surface of the second opposite member engage with each other and form a crease protruding in a second direction reverse to the first direction on the recording medium, depending on an output destination of the recording medium.

2. The post-processing apparatus according to claim 1 , wherein the recording medium includes a plurality of pages by a predetermined number, and a page of the recording medium on which a crease is formed is selected from the plurality of pages depending on the output destination of the recording medium.

3. The post-processing apparatus according to claim 1 , wherein the recording medium includes a plurality of pages having a group of images, and the output destination includes a saddle stitching and folding processor that forms a saddle-stitched booklet by folding the recording medium.

4. The post-processing apparatus according to claim 1 , wherein the protrusion and the recess have substantially round shapes in a sectional view in a direction intersecting with a transport direction of the recording medium.

5. An image forming system, comprising
an image forming apparatus that forms an image on a sheet; and
the post-processing apparatus according to claim 1 .
