(a) in which, when a staple pulley of a staple drive assembly is rotated in a first direction around a first shaft, a staple link assembly connected to the staple pulley and a reciprocating assembly of a cartridge connected to the staple link assembly are moved along a second shaft toward a distal end of the cartridge;
(b) in which, when the reciprocating assembly is moved toward the distal end of the cartridge, an operation member in contact with the reciprocating assembly is moved toward the distal end of the cartridge together with the reciprocating assembly;
(c) in which, as the operation member is moved toward the distal end of the cartridge, the operation member ejects staples in the cartridge to outside of the cartridge, and simultaneously, a blade of the operation member is moved toward the distal end of the cartridge; and
(d) in which, when the staple pulley is rotated in a second direction opposite to the first direction around the first shaft, the staple link assembly, which is connected to the staple pulley, and the reciprocating assembly of the cartridge, which is connected to the staple link assembly, are moved toward a proximal end of the cartridge.
