Sheet staple feeding mechanism

Abstract

A feeding mechanism for sheet staple comprises a reciprocating member (12) which is provided under a cartridge in which stacked sheet staples are contained and which is reciprocated forwardly and backwardly in response to up and down movements of a driver for driving the sheet staples, a feeding pawl (20) mounted rotatably by a predetermined angle in forward and backward directions on the reciprocating member (12) for rotating in a raised direction as the reciprocating member moves forwardly, and a spring (13) for biasing forwardly the reciprocating member (12). Each of the sheet staples is fed out forwardly by raising of the feeding pawl (20). One end of the spring (13) is engaged in a lower side than a center of rotation of the feeding pawl (20). The reciprocating member (12) is urged forwardly through the feeding pawl (20).
