Abstract

An electric stapler is provided with: a base (B); and a stapler main body ( 1 ) arranged on the base (B). The stapler main body ( 1 ) is provided with: a driver unit ( 2 ) including a driver for driving a staple (S) to pierce through sheets of paper (P); a clincher unit ( 3 ) including a clincher for clinching the driven staple; and a table ( 4 ) provided on one of the driver unit ( 2 ) and the clincher unit ( 3 ). The stapler main body ( 1 ) is supported to be displacable with respect to the base (B). The table ( 4 ) is configured to be movable between a first position and a second position apart from the first position in a direction where the driver drives the staple, in accordance with a displacement of the stapler main body ( 1 ) with respect to the base (B).

First claim

What is claimed is:

1. An electric stapler comprising:
a base;
a stapler main body arranged on the base and including a driver unit having a driver for driving a staple to pierce through sheets of paper, a clincher unit having a clincher for clinching the driven staple, and a table provided on one of the driver unit and the clincher unit and on which the sheets are supported in a direction in which the sheets are stacked during a stapling action; and
a supporting mechanism configured to support the stapler main body to be displaceable with respect to the base,
wherein the table is configured to be movable between a first position and a second position spaced apart from the first position in a direction in which the driver drives the staple, in accordance with a displacement of the stapler main body with respect to the base,
wherein the stapler main body is displaced together with said one of the driver unit and the clincher unit by an increase in a clamping force of a clamping action in which the sheets are clamped by bringing the other of the driver unit and the clincher unit close to said one of the driver unit and the clincher unit in the stapling action, such that the table moves to the second position, and
wherein the stapler main body is supported to displace with respect to the base in a manner of a parallel translation in a direction in which the driver drives the staple toward the sheets.

2. The electric stapler according to claim 1 , wherein, at said first position, the table positions in a different level from one of surfaces of the sheets in a space between the driver unit and the clincher unit, and
at said second position, the table and said one of surfaces of the sheets constitute a substantially coplanar plane.

3. The electric stapler according to claim 1 , wherein the electric stapler is provided in a paper processing equipment,
at said first position, the table positions in a different level from a loading surface on which the sheets are loaded and which is formed on a guide plate provided in the paper processing equipment, and
at said second position, the table and the loading surface constitute a substantially coplanar plane.

4. The electric stapler according to claim 1 , wherein the base is fixed on a frame member provided in a paper processing equipment.

5. The electric stapler according to claim 1 , wherein the base is disposed on a frame member provided in a paper processing equipment so that the base is movable along a direction of an edge of the sheets.

6. The electric stapler according to claim 1 , wherein the base is disposed on a frame member provided in a paper processing equipment so that the base is movable in a direction close-toward/apart-from an edge of the sheets.

7. The electric stapler according to claim 1 , wherein an electric motor configured to drive both the driver unit and the clincher unit is mounted within the stapler main body,
wherein a displacement movement of the stapler main body with respect to the base is powered by said electric motor, and
the electric motor is arranged within the stapler main body so that a whole of the electric motor is also displaceable with respect to the base in accordance with the displacement movement of the stapler main body.

8. The electric stapler according to claim 1 , wherein the stapler main body is configured to displace with respect to the base in accordance with the stapling action of the driver unit or the clincher unit.

9. The electric stapler according to claim 1 , wherein the stapler main body is displaced together with the driver unit by the increase in the clamping force of the clamping action in which the sheets are clamped by bringing the clincher unit close to the driver unit in the stapling action, such that the table moves to the second position.

10. An electric stapler comprising:
a base;
a stapler main body arranged on the base and including a driver unit having a driver for driving a staple to pierce through sheets of paper, a clincher unit having a clincher for clinching the driven staple, and a table provided on one of the driver unit and the clincher unit and on which the sheets are supported in a direction in which the sheets are stacked during a stapling action; and
a supporting mechanism configured to support the stapler main body to be displaceable with respect to the base,
wherein the table is configured to be movable between a first position and a second position spaced apart from the first position in a direction in which the driver drives the staple, in accordance with a displacement of the stapler main body with respect to the base,
wherein a projection portion is formed on a cam arranged on a driving shaft provided on said one of the driver unit and the clincher unit on which the table is provided,
wherein a cam follower that is engagable with the projection portion is provided to the base, and
wherein the cam follower is engaged with the projection portion in a standby state to restrict a displacement of the stapler main body.

11. An electric stapler comprising:
a base;
a stapler main body arranged on the base and including a driver unit having a driver for driving a staple to pierce through sheets of paper, a clincher unit having a clincher for clinching the driven staple, and a table provided on one of the driver unit and the clincher unit and on which the sheets are supported in a direction in which the sheets are stacked during a stapling action;
a supporting mechanism configured to support the stapler main body to be displaceable with respect to the base;
a cam arranged on a driving shaft provided on said one of the driver unit and the clincher unit on which the table is provided; and
a cam follower provided on the base and engaged with the cam,
wherein the table is configured to be movable between a first position and a second position spaced apart from the first position in a direction in which the driver drives the staple, in accordance with a displacement of the stapler main body with respect to the base,
wherein the stapler main body is displaced with respect to the base by rotating the cam to change a distance between the driving shaft and the cam follower, such that the table moves to the second position,
wherein a second cam is arranged on the driving shaft,
wherein a projection portion is formed on the second cam,
wherein a second cam follower that is engagable with the projection portion is provided to the base, and
wherein the second cam follower is engaged with the projection portion in a standby state to restrict a displacement of the stapler main body.
