Abstract
In a staple case provided with a staple pull-out opening and a lower face opening, a roll staple is contained, so that the staple case can be directly installed in a staple cartridge. When the staple cartridge is loaded in an electric stapler, a staple-feeding roller is in contact with the roll staple. As the staple-feeding roller rotationally drives the roll staple, a leading edge of the roll staple is fed to a leading edge of a guide portion of the staple cartridge through the staple pull-out opening.
