Abstract

Two slide bases (106) synchronizingly traveled on linear guides (105) arranged in parallel with each other are rotatably attached with a clincher unit (103) and a driver unit (104) and provided with a click stop mechanism for fixing the clincher unit (103) and the driver unit (104) at a 0 degree position or a 45 degree rotated position. When the driver unit and the clincher unit are traveled from an initial position to a skewed binding position, the 0 degree claw portion (119) impinges on the stopper pin (121) and the driver unit and the clincher unit are rotated to the 45 degree rotated position to fix. When the driver unit and the clincher unit are traveled reversely to the initial position, the 45 degree claw portion (120) impinges on the stopper pin (121) and the driver unit and the clincher unit are returned to the 0 degree position to fix.

Claims

1. An electric stapler comprising:

a driver unit;

a clincher unit arranged to be opposed to the driver unit in an up and down direction;

a transversely moving mechanism for transversely moving the driver unit and the clincher unit;

a horizontally rotating mechanism for simultaneously horizontally rotating the driver unit and the clincher unit to a predetermined angle with respect to the linear guide member so as to perform stapling and clinching at said predetermined angle;

two linear rails arranged in parallel with each other in the up and down direction;

slide bases respectively attached to the two linear rails;

a synchronizingly drive mechanism for synchronizingly traveling the two slide bases;

a click stop mechanism capable of fixing the driver unit and the clincher unit to a first position and a second position;

claw portions provided at respective outer peripheral portions of the driver unit and the clincher unit in correspondence with the first position and the second position; and

a stopper member arranged at a skewed binding position on a traveling path;

wherein one of the slide bases is attached with the driver unit horizontally rotatably, the other of the slide bases is attached with the clincher unit horizontally rotatably, and the driver unit and the clincher unit are made to be opposed to each other; and

wherein when the driver unit and the clincher unit are traveled from an initial position to the skewed binding position, the claw portion at the first position impinges on the stopper member, and the driver unit and the clincher unit are fixed to the second position, and

when the driver unit and the clincher unit are traveled reversely to the initial position, the claw portion at the second position impinges on the stopper member and the driver unit and the clincher unit are rotated to the first position.

2. The electric stapler according to claim 1, wherein the first position is a 0 degree position and a second position is a 45 degree rotated position.

3. The electric stapler according to claim 1, wherein the stopper member is either a stopper pin or a projected portion.

4. An electric stapler comprising:

a frame;

two linear guide members provided at the frame and arranged in parallel with each other;

a clincher unit mounted to one of the linear guide member;

a driver unit mounted to the other of the linear guide members;

a horizontally rotating mechanism for simultaneously horizontally rotating the driver unit and the clincher unit to a predetermined angle with respect to the linear guide member so as to perform stapling and clinching at said predetermined angle;

a synchronizing moving mechanism for synchronizingly traveling the clincher unit and the driver unit; and

slide ways at the frame brought into contact with respective rear faces of the clincher unit and the driver unit,

wherein a front face of the driver unit is made to be opposed to a front face of the clincher unit, and

wherein in binding operation, slide ways receive reaction forces operated to the clincher unit and the driver unit.

5. An electric stapler comprising:

a clincher unit mounted to a first linear guide member;

a driver unit mounted to a second linear guide member;

a transversely moving mechanism for transversely moving the driver unit and the clincher unit; and

a horizontally rotating mechanism for simultaneously horizontally rotating the driver unit and the clincher unit to a predetermined angle with respect to the linear guide member so as to perform stapling and clinching at said predetermined angle, and

wherein the clincher unit is arranged opposite to the driver unit in an up and down direction.

6. The electric stapler according to claim 5, wherein the first and second linear two guide members are arranged in parallel with each other in the up and down direction, and wherein slide bases are respectively attached to each of the first and second linear guide members.
