Stapler cartridge and stapler apparatus comprising the same

摘要

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.
