Electric stapler

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.
