Abstract

A staple storage unit includes return prevention members that prevent a staple positioned for driving from moving back toward the staple storage portion of the staple storage unit. A plurality of staple abutting portions 105 a and 105 b are spaced along the draw out direction of the staple band 101 at distances where they do not all abut the staple linking portion 105 d , thereby increasing the likelihood that at least one of the staple abutting portions will engage the staple linking portion to prevent significant withdrawal of the staple sheet back toward the staple storage portion.

wherein there are M staple abutting portions and wherein an individual staple has a width L along the staple feed direction, the plurality of staple abutting portions being spaced apart such that successive staple abutting portions are spaced by a distance of n*L+L/M, where n is a natural number.

6. The staple storage device of claim 5 , wherein the return prevention device includes a body portion and the plurality of staple abutting portions extend from the body portion.

7. The staple storage device of claim 6 , wherein the return prevention device includes a second plurality of staple abutting portions extending from the body portion and spaced from the first plurality of staple abutting portions in a direction normal to the staple feed direction.
