Abstract

A cartridge for an electric stapler comprises an inner cartridge for holding a plurality of staple sheets in multi-layered form, each of the stapler sheets being formed by sticking straight staples together in sheet-like form, and an outer cartridge associated with the inner cartridge and detachably mounted on the electric stapler. The outer cartridge includes an accommodating section for accommodating the inner cartridge, a staple passage formed so as to extend from a lower end of the accommodating section, a staple receiving stand disposed at a front end of the staple passage, a pusher for pushing legs of a staple forward, the staple being formed into a square U-shape on the staple receiving stand, and a drive channel, arranged at the front of the staple passage, for receiving the formed staple pushed by the pusher. A driver plate of the main body of the stapler drives the formed staple in a direction orthogonal to the staple passage.
