Abstract

A post-processing apparatus includes a side edge part removing portion that removes a side edge part from a sheet; a side edge part housing section that houses the side edge part removed by the side edge part removing portion and that is able to be pulled out from an apparatus body; and a guide plate that is inclined in a direction intersecting with a moving direction of the side edge part and guides the side edge part removed by the side edge part removing portion along the moving direction of the side edge part to the side edge part housing section.

First claim

What is claimed is:

1 . A post-processing apparatus comprising:
a side edge part removing portion that removes a side edge part from a sheet; a side edge part housing section that houses the side edge part removed by the side edge part removing portion and that is able to be pulled out from an apparatus body; and a guide plate that is inclined in a direction intersecting with a moving direction of the side edge part and guides the side edge part removed by the side edge part removing portion along the moving direction of the side edge part to the side edge part housing section.

2 . The post-processing apparatus according to claim 1 ,
wherein the guide plate includes inclined surfaces defining a substantially valley shape having a center portion and both end portions along the moving direction of the side edge part, the both end portions being higher than the center portion.

3 . The post-processing apparatus according to claim 1 , further comprising:
a second guide plate arranged below the guide plate and including inclined surfaces defining a substantially mountain shape having a center portion and both end portions along the moving direction of the side edge part, the both end portions being lower than the center portion.

4 . The post-processing apparatus according to claim 3 ,
wherein a portion on a distal end side of each of the inclined surfaces of the guide plate is bent downward along the moving direction of the side edge part to increase a gap between the guide plate and the second guide plate along the moving direction of the side edge part.

5 . The post-processing apparatus according to claim 1 , further comprising:
a leveling member that is provided below the guide plate and levels a height of the side edge part stacked in the side edge part housing section.

6 . The post-processing apparatus according to claim 5 ,
wherein the leveling member includes a first leveling member disposed at a position at a distance L 1 from an end portion on a near side in a pull-out direction of the side edge part housing section and a second leveling member disposed at a position at a distance L 2 from an end portion on a deep side in the pull-out direction of the side edge part housing section, and the distance L 1 and the distance L 2 satisfy conditions as follows for a distance L 3 between the first level member and the second leveling member, 2×L 1 <L 3 , and 2×L 2 ≦L 3 .

7 . The post processing apparatus according to claim 5 ,
wherein the leveling member rotates forward and backward in the direction intersecting with the moving direction of the side edge part, and a number of rotations of the first and second leveling members in a direction to approach one another is larger than a number of rotations of the first and second leveling members in a direction to separate from one another.

8 . 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 .
