Abstract
A driver 12 is provided so that it can move up and down, and a C-shaped leading-end staple of sheet-shaped connected-staples 1 is pressed to a guide surface 15 by a pusher 13 so as to be opposed to a leading end of the driver 12. The pusher 13 includes a support surface 13b which is positioned near and under a center of the staple and protrudes so that one part of the support surface faces to an inside of at least the substantially C-shaped leading-end staple 1. Therefore, it is possible to prevent a cutting noise from being produced when the leading-end staple is torn off from the next staple in order to drive the leading-end staple in sheets of paper to be stapled.
