Abstract: A stapler that can push staples into a surface of a paper bundle regardless of thickness of the paper bundle is provided. An exemplary embodiment of the stapler includes a vertical movement section for causing an operating handle to vertically descend together with a staple mounting magazine by pressing the operating handle while keeping the operating handle at a predetermined angle, a post-vertical movement rotating section for causing the operating handle to rotate after the staple mounting magazine vertically descends to come into contact with the paper bundle placed on a horizontal base, and a vertical position fixing section for fixing a vertical position of the staple mounting magazine by starting the rotation of the operating handle.

Abstract: A staple storage cassette, comprising a staple assembly slidably installed on a cassette rail member across a pair of guide rails vertically formed parallel with each other, a feeder slidably brought into contact with the rear end part of the staple assembly, and a cassette cover member forming a passage in which staples and the feeder are inserted. A stopper is installed and a blade guide hole is formed at the front end part of the cassette cover member, and engagement recessed parts engaged with the elastically engaged claw pieces of the feeder in one direction are continuously formed in the inner surface of the cassette cover member in the longitudinal direction so that the feeder can be moved in the forward direction only.

Abstract: A stapler that can push staples into a surface of a paper bundle regardless of thickness of the paper bundle is provided. A stapler including vertical movement means (24) for causing an operating handle (12) to vertically descend together with a staple mounting magazine (13) by pressing the operating handle (12) while keeping the operating handle at a predetermined angle, post-vertical movement rotating means (18, 27) for causing the operating handle (12) to rotate after the staple mounting magazine (13) vertically descends to come into contact with the paper bundle placed on a horizontal base, and vertical position fixing means (21, 22, 28) for fixing a vertical position of the staple mounting magazine (13) by starting the rotation of the operating handle (12) has been constructed.
