Abstract

A stapler includes: a driver configured to drive a staple into a sheet, the staple having a crown and a pair of legs; a clincher configured to bend the legs driven into and penetrating the sheet; and a support portion configured to support the driver such that the driver is movable in a driving-in direction of the staple, in which the support portion is configured to pivotably support the driver such that the driver is rotatable along an axial direction of the crown in a state where the staple is set in a driving-in position.

Claims (40)

1 . A stapler comprising:

a driver configured to drive a staple into a sheet, the staple having a crown and a pair of legs;

a clincher configured to bend the legs driven into and penetrating the sheet; and

a support portion configured to support the driver such that the driver is movable in a driving-in direction of the staple,

wherein the support portion includes an attachment part, and

wherein the attachment part is configured to pivotably support the driver relative to the support portion such that the driver is rotatable about a rotational axis that is relative to the support portion, the rotational axis being perpendicular to the driving-in direction of the staple and, with the staple set in a driving-in position, perpendicular to an axial direction of the crown.

2 . The stapler according to claim 1 , further comprising:

a guide portion configured to guide the driver in the driving-in direction when the staple is driven into the sheet by the driver.

3 . The stapler according to claim 1 , wherein the attachment part of the support portion is configured to pivotably support a center position of the driver in the axial direction.

4 . The stapler according to claim 3 , wherein the support portion includes:

a driver attachment portion as the attachment part, the driver attachment portion being configured to pivotably support the driver; and

a driver shaft extending along the axial direction and configured to move the driver attachment portion in the driving-in direction.

5 . The stapler according to claim 4 ,

wherein the driver and the driver shaft are rotatable relative to each other so that the driver faces the driving-in direction.

6 . The stapler according to claim 5 ,

wherein the driver attachment portion includes a support shaft, and

wherein the rotational axis corresponds to a longitudinal axis of the support shaft, the rotational axis being orthogonal to the driver shaft.

7 . The stapler according to claim 4 , wherein the driver attachment portion has an acting portion that is contactable with the driver shaft to receive a force for moving the driver in the driving-in direction and a force for moving the driver in an opposite direction opposite to the driving-in direction.

8 . The stapler according to claim 4 , further comprising:

an operating component configured to operate the driver.

9 . The stapler according to claim 3 , wherein the support portion includes a driver shaft extending in the axial direction, the driver shaft being configured to pivotably support the driver to move the driver in the driving-in direction.

10 . A binding device comprising:

a plurality of staplers, each of the staplers including:

a driver configured to drive a staple into a sheet, the staple having a crown and a pair of legs;

a clincher configured to bend the legs driven into and penetrating the sheet; and

a support portion configured to support the driver such that the driver is movable in a driving-in direction of the staple,

wherein the support portion includes an attachment part,

wherein the attachment part is configured to pivotably support the driver relative to the support portion such that the driver is rotatable about a rotational axis that is relative to the support portion, the rotational axis being perpendicular to the driving-in direction of the staple and, with the staple set in a driving-in position, perpendicular to an axial direction of the crown,

wherein the attachment part of the support portion is configured to pivotably support a center position of the driver in the axial direction, and

wherein the support portion further includes:

a driver attachment portion as the attachment part, the driver attachment portion being configured to pivotably support the driver; and

a driver shaft extending along the axial direction and configured to move the driver attachment portion in the driving-in direction; and a single operating component configured to operate the plurality of the staplers, wherein the driver shaft of the plurality of staplers is a single driver shaft passing through each of the driver attachment portions of the plurality of staplers.

11 . The binding device according to claim 10 ,

wherein the driver and the driver shaft are rotatable relative to each other so that the driver faces the driving-in direction.

12 . The binding device according to claim 11 ,

wherein the driver attachment portion includes a support shaft, and

wherein the rotational axis corresponds to a longitudinal axis of the support shaft, the rotational axis being orthogonal to the driver shaft.

13 . The binding device according to claim 10 , wherein the driver attachment portion has an acting portion that is contactable with the driver shaft to receive a force for moving the driver in the driving-in direction and a force for moving the driver in an opposite direction opposite to the driving-in direction.

14 . The binding device according to claim 10 , further comprising:

an operating component configured to operate the driver.
