ABSTRACT:
Disclosed is a stapler which comprises a main body portion having at its one end a staple accommodating portion provided with a staple drive-out opening, a pressing lever portion pivotally attached at its one end to the other end of the main body portion, and a base portion having a guide groove disposed at a position which comes in opposition to the staple drive-out opening for curving stapling leg portions of one staple so as to be close to each other. The staple drive-out opening is formed to be narrower in width at a lower staple driving-out side than an upper staple pressing side, whereby when the staple is driven out of the staple drive-out opening, the stapling leg portions of the staple is forcedly curved so as to make the respective free ends of the staple drive-out opening come into contact with each other while piercing into an object to be stapled. Accordingly, fixing of flaps of a box, fixing of a slip or the like on a box, etc., can be performed without putting the guide groove of the base portion on the under surface of the object to be stapled.
