ABSTRACT:
A stapler including a staple extruding member, a staple magazine and a base plate, which are pivotally held together by means of a pin. Underneath the staple magazine is fitted a sliding member of a specified thickness and shape so as to cover only one side of the staple ejection slot at the front of the staple magazine. The sliding member is mounted on the magazine so as to move from a position underneath the staple ejection slot to a position away from the staple ejection slot and closer to the pin. The staple magazine is adapted to receive a staple holding block, which block carried staples upon its upper surface. The staple holding block is provided with a hollow which extends longitudinally of the block and is open to the upper and lower surfaces of the block by means of a split groove. Inside this hollow is fitted a columnar spring bearing portion of a magazine follower. A detachable spacer may be fitted to the staple ejection slot at the end of the magazine. In addition the staple ejection slot may be provided with a two-step opening for ejection of staples with different lengths and strike area widths.
