Abstract

A post-processing device includes a stacking portion on which a medium having an image recorded thereon is stacked; an aligning portion that is disposed on the stacking portion and that aligns a position of an edge of the medium; a drawing member that draws the medium stacked on the stacking portion toward the aligning portion; and a guiding member that is disposed above the drawing member and that guides the medium that is transported toward the stacking portion, the guiding member including a vicinity portion that is in a vicinity of the drawing member and that is recessed so as to receive the drawing member.

First claim

What is claimed is:

1. A post-processing device comprising:
a stacking portion configured to stack a medium having an image recorded thereon;
an aligning portion that is disposed on the stacking portion and that is configured to align a position of an edge of the medium;
a drawing member configured to draw the medium stacked on the stacking portion toward the aligning portion; and
a guiding member that is disposed above the drawing member and that is configured to guide the medium that is transported toward the stacking portion, the guiding member including a vicinity portion that is in a vicinity of the drawing member and that is recessed so as to be configured to receive the drawing member,
wherein the drawing member includes:
a rotating shaft portion; and
a drawing portion that extends in a radial direction from the rotating shaft portion and

wherein the recessed vicinity portion comes into contact with the drawing portion and includes an oblique surface that is at an angle with respect to an axial direction of the rotating shaft portion.

2. The post-processing device according to claim 1 ,
wherein a downstream portion of the vicinity portion in a direction in which the medium is transported is at an angle with respect to the direction in which the medium is transported.

3. An image forming apparatus comprising:
an image recording unit configured to record an image on a medium; and
the post-processing device according to claim 1 , wherein the post-processing device is configured to perform post-processing on the medium having the image recorded thereon by the image recording unit.
