ABSTRACT:
A stapler having a driver unit vertically separated from its clincher unit, which has a clincher base with a clincher. The clincher base is disposed to vertically reciprocate, and sheets inserted between the base and driver unit are clamped between the base and the driver unit when the base is reciprocated. The stapler has a first motor to operate the driver, and a second motor to reciprocate the clincher base and operate the clincher. In sequence, the second motor reciprocates the base and makes the base clamp the sheets, and then stops; the first motor makes the driver drive out the staple, and then stops; the second motor makes the clincher clinch the staple legs having passed the sheets, the base is returned, and the second motor stops; and after clinching, the first motor returns the driver to the initial position, and then stops.
