Abstract: The present invention is to provide a staple cartridge that can offset any discrepancies when mounting a staple cartridge, even if staples are slightly offset to check the occurrence of stapling defects. The staple cartridge 100 of the holding means 200 which is equivalent to the cartridge holder disposed as either a body separate to the stapler unit 300 or unitized thereto, actuates the staple feeds means 202. Even if the position of the staple pulled out from the staple cartridge is offset, this action corrects the offset to correctly set the staple at the driving position thereby enabling it to check stapling defects that occur because of mis-positioning of the staple set position.

Abstract: [Issue] This invention prevents mis-positioning of staples when driving staples and checks the occurrence of binding problems by smoothly driving staples.

Abstract: A stapler is provided that does not waste any staples when a staple cartridge or sheet of staples is replaced. The stapler includes a sheet of staples, a mounting unit equipped with a cartridge for housing the sheet of staples and a driver mechanism that draws out the sheet of staples from the cartridge. The mounting unit has a reverse motion stopping mechanism that prevents the sheet of staples from moving back into the cartridge. The reverse motion stopping mechanism makes contact with the sheet of staples when the mounting unit is installed and the reverse motion stopping mechanism releases contact with the sheet of staples when the mounting unit is removed.

Abstract: A cartridge is provided that reliably feeds staples even when the sheet of staples is completely unraveled. A shaft is established in the housing unit for the cartridge as a mechanism for forming a space. The shaft is not centered inside the round housing unit but is instead off-center. In other words, the shaft is located beneath the center line of the housing unit. Also, the shaft is located completely inside the hollow cavity formed by the rolled sheet of staples. As a result, the sheet of staples does not come into contact with the interior walls of the housing unit even when the rolled sheet of staples is unraveled.

Abstract: A stapler is provided that consistently remove only jammed staples from the stapler. Guide grooves are formed in a guide unit of a cartridge, and the guide grooves support a sheet of staples. Stoppers are formed on the edge of the walls of the guide unit to block the ends of the guide grooves. Release holes that open upwardly are formed in the guide grooves in front of the stoppers. Because a jammed staple protrudes from the release holes, the jammed staple can be pulled out from the release holes using the fingers. As a result, jammed staples can be effectively removed from the stapler.
