ABSTRACT:
A clip driver is used for driving elastic clips each having a back portion, and abutment portions for clipping edge portions of sheet-members between the opposite ends of the abutment portions. The clip driver includes a casing body for accommodating the clips and including a sheet-member insertion inlet formed at a front end, a clip insertion inlet formed at a rear end, a longitudinally extending opening formed in a front end upper surface, a clip path formed so as to extend from the sheet-member insertion inlet to the clip insertion inlet, and clip stopper portions for engagement with the clips so as to allow the clips to advance but prevent the clips from retreating; clip opening springs disposed in the vicinity of the sheet-member insertion inlet for opening a nip between the abutment portions of the frontmost clip; an operation knob longitudinally movably fitted into the opening for feeding the frontmost clip in the clip path toward the sheet-member insertion inlet over the clip opening springs by means of the front end of the operation knob; a feed member movable together with the operation knob and having feed protrusions which make a second and following clips advance simultaneously when the feed member advances, while the feed member can retreat without making the advanced clips retreat by the feed protrusions; and an elastic member always elastically biasing the operation knob and the feed member toward the rear end of the casing body.
