  • Patent number: 9085088
    Abstract: A stapler includes a driver mechanism and a clincher mechanism. The clincher mechanism includes a base, a clincher resiliently supported on the base such that the clincher is biased toward the driver mechanism, and a clincher guide having a guide portion configured to guide a movement of the clincher. The guide portion has an inner peripheral surface that forms a through hole extending through the clincher guide and surrounds an outer periphery of the clincher. The inner peripheral surface has recessed surface portions extending from a surface of the clincher guide facing the driver mechanism, such that a gap is provided between the clincher and the recessed surface portions. The recessed surface portions are formed at locations corresponding to portions of the clincher where distal ends of the leg portions of the staple hit.

  • Patent number: 8365970
    Abstract: An electric stapler includes: a driver for driving leg portions of a staple having a U-shaped section to penetrate the leg portions through a paper bundle; a table including a clincher for bending and forming the penetrated leg portions inwardly, the table for holding the paper bundle between the driver and the table; a motor for moving the table and the driver; a photo sensor for detecting an existence of the paper bundle inserted into a gap between the table and the driver; and a control portion for driving the motor. The photo sensor is disposed on the table in such a manner that a detection point of the photo sensor for detecting the paper bundle exists upwardly of a disposing position of the clincher by inclining an optical axis direction of a radiation light to be emitted from the photo sensor in a direction of the clincher.

  • Patent number: 8261957
    Abstract: Immediately after a clinch lever causes a clinch link to clinch the leg of a staple which penetrates sheets of paper to be stapled, a pressure by the clinch lever with respect to the clincher link is temporarily reduced by a pressure reducing unit. Therefore, a clincher moves down in a state where the clincher still receives the press-contacting force from a driver plate. Accordingly, the looseness occurs between the driver plate and the clincher link. A fixing plate becomes easy to draw out as much as the looseness. If the fixing plate is set to be drawn out at this timing, it can be simply drawn out to be moved to the initial position.
