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.
