Abstract
A stapling mechanism includes a base, a chute and a cover pivotally coupled together at one end. A guide rail is disposed in the chute for slidably supporting staples and a pusher may push the staples toward the free end of the chute for engaging with a drive plunger. The guide rail includes a recess formed in the upper portion of the free end for allowing engagement of the staples with the bottom surface of the chute so as to suitably guide the staples and so as to prevent the inclination of the staples.
