Abstract
A stapler has a table formed with a clincher mechanism at a front end and is rotatably supported on a frame. A pair of locking plates slidably supported along the frame between the table and the frame prevents the clincher mechanism from rotating in a direction in which the clincher mechanism moves toward a staple driving section. Drive cams are provided independently for each of the locking plates to drive the locking plates. The times at which the respective locking plates are pulled out from between the table and the frame by the respective drive cams are shifted from each other.
Claims6
A stapler comprising:
- a frame;
- a table which is rotatably supported on the frame;
- a pair of side pieces which is integrally formed on respective sides of the table in order to rotatably support the table;
- a first and a second locking plates which are slidable along the frame between a position in which the table is prevented from rotating and a position in which the table is allowed to rotate;
- and
- a first and a second drive cams operable to drive the first and the second locking plates respectively,
- wherein a first cam face formed on the first drive cam and a second cam face formed on the second drive cam are different in shape,
- wherein a first timing, at which the first cam face starts to drive the first locking plate to move from the position in which the table is prevented from rotating to the position in which the table is allowed to rotate is different than a second timing, at which the second cam face starts to drive the second locking plate to move from the position in which the table is prevented from rotating to the position in which the table is allowed to rotate.
