There is provided a stapler including: a driving portion that drives a staple into a sheet bundle; a clinch portion that bends a leg portion of the staple driven into and penetrating the sheet bundle; a table link that supports the clinch portion at a position facing the driving portion and move the clinch portion in a first direction where the clinch portion separated from and brought into contact with the driving portion; a motor that drives the driving portion; and a regulation portion that moves in a second direction intersecting the first direction while abutting against the table link and regulate a movement of the clinch portion in a direction away from the driving portion. A position where the regulation portion abuts against the table link changes in a direction toward the clinch portion as the clinch portion and the driving portion are separated from each other.

First claim

What is claimed is:

1 . A stapler comprising:
a driving portion configured to drive a staple into a sheet bundle; a clinch portion configured to bend a leg portion of the staple driven into and penetrating the sheet bundle; a table link configured to support the clinch portion at a position facing the driving portion and move the clinch portion in a first direction in which the clinch portion is separated from and brought into contact with the driving portion; a motor configured to drive the driving portion; and a regulation portion configured to move in a second direction intersecting the first direction while abutting against the table link and regulate a movement of the clinch portion in a direction away from the driving portion, wherein the table link has one end side to which the clinch portion is attached, the other end side which is rotatably supported by a shaft, and an abutting portion against which the regulation portion abuts between the clinch portion and the shaft, and a position where the regulation portion abuts against the table link: changes in a direction toward the clinch portion as the clinch portion and the driving portion are separated from each other; and changes in a direction away from the clinch portion as the clinch portion and the driving portion approach each other.

2 . The stapler according to claim 1 , further comprising:
a lock plate having the regulation portion; and a frame abutting portion configured to support the lock plate to be movable along the second direction, wherein the lock plate has a guide portion that is guided by the frame abutting portion.

3 . The stapler according to claim 2 , wherein
the lock plate includes a plurality of guide portions including the guide portion provided along the second direction, and the regulation portion is provided between the plurality of guide portions.

4 . The stapler according to claim 2 , wherein

5 . The stapler according to claim 2 , wherein
the frame abutting portion is an opening shaped in an elongated hole, and is configured to guide the guide portion to be movable horizontally.

6 . The stapler according to claim 1 , wherein
the abutting portion is formed by a grooved cam extending in a direction away from the clinch portion.

7 . The stapler according to claim 1 , wherein
the abutting portion is a grooved cam that penetrates through a front and back of the table link, and is shaped in an elongated hole extending in a direction away from the clinch portion.
