Abstract
Disclosed is a stapler and a staple to be used in the stapler, by which a slip or the like can be permanently or temporarily fastened with the staple onto ground paper, corrugated cardboard, or the like so that the slip or the like can be easily removed therefrom without taking off the staple. The staple has one supporting portion and one stapling leg portion bent at one end of the supporting portion substantially perpendicularly thereto. The stapler has a staple accommodating portion, wherein a forward one of the staples is always located at a staple drive-out opening formed at the forward end of the staple accommodating portion. The staple accommodating portion has a body and a staple holder mounted in the body. The holder has a side portion disposed so as to form an interval between the side portion and one side wall of the body and a horizontal portion extending substantially horizontally from the upper end of the side portion to the other side wall of the body to thereby hold the supporting portion of the staple. Only the one stapling leg portion pierces ground paper and is bent at the rear surface of the ground paper to nip the ground paper.
