Abstract

A post-processing device includes a processing tray on which a medium on which recording was performed by a recording unit is loaded, a rear end alignment unit that aligns a rear end (an example of an end portion) of the medium on the processing tray, a post-processing unit that performs post-processing on the medium aligned by the rear end alignment unit, and a pressing member that presses the rear end of the medium. The post-processing unit is configured to be movable. The pressing member is provided to be rotatable in conjunction with movement of the post-processing unit, in a state in which the pressing member is in contact with the medium aligned by the rear end alignment unit.

First claim

What is claimed is:

1. A post-processing device comprising:
a processing tray at which is loaded a medium on which recording was performed by a recording unit;
an alignment unit configured to align an end portion of the medium at the processing tray; and
a post-processing unit configured to perform stapling on the medium aligned by the alignment unit, and including two pressing members configured to press the end portion of the medium, each pressing member being disposed on one of both sides of the post-processing unit, wherein
the post-processing unit and the pressing members are configured to integrally move,
in a state where the pressing members are in contact with the medium aligned by the alignment unit.

2. The post-processing device according to claim 1 , wherein
the pressing members include a rotational axis extending in a direction orthogonal to a movement direction of the post-processing unit, and the pressing members are configured to rotate in conjunction with the movement of the post-processing unit.

3. The post-processing device according to claim 2 , wherein
the pressing members form a conical shape and includes a top portion facing upstream in a transport direction of the medium, and
the pressing members are configured to rotate about the rotational axis passing through the top portion.

4. The post-processing device according to claim 1 , wherein
the pressing members are spherical, and
the pressing members are provided rotatably in a transport direction of the medium and in a movement direction of the post-processing unit.

5. The post-processing device according to claim 1 , wherein
the pressing members are provided on both of sides in a movement direction of the post-processing unit.

6. The post-processing device according to claim 1 , wherein
the pressing members are pressed toward a loading surface of the processing tray.

7. The post-processing device according to claim 1 , wherein
the pressing members are pressed upstream in a transport direction of the medium.

8. The post-processing device according to claim 1 , wherein
the pressing members are provided separably from the medium,
the pressing members are separated from the medium when the medium is being aligned by the alignment unit, and
the pressing members are in contact with the medium when the post-processing unit moves and when the stapling is performed on the medium.

9. The post-processing device according to claim 1 , wherein
the pressing members are provided on both sides of the post-processing unit.

10. A post-processing device comprising:
a processing tray at which is loaded a medium on which recording was performed by a recording unit;
an alignment unit configured to align an end portion of the medium at the processing tray; and
a post-processing unit configured to perform punching on the medium aligned by the alignment unit, and including two pressing members configured to press the end portion of the medium, each pressing member being disposed on one of both sides of the post-processing unit, wherein
the post-processing unit and the pressing members are configured to integrally move, in a state where the pressing members are in contact with the medium aligned by the alignment unit.
