ABSTRACT:
A stapler includes a staple magazine rotably connected to an operating assembly. The operating assembly rotates around a shaft in response to pressure applied by a user to a operating handle. The staple magazine includes a plurality of staple clips capable of holding different size staples. The stapler includes means for determining a desired staple size. The staple magazine is rotated by the user to select a desired size staple. A stopper assembly, slidably mounted on a base of the stapler, is positioned by the user to limit and guide a front edge of a stack of papers being stapled. The means for determining a desired staple size and the stopper assembly are free from interference with each other. The stopper assembly is constructed so that a portion contacting the front edge of the stack of papers remains perpendicular to the front edge during a stapling operation.
