Abstract
An electronic stapler suitable to accommodate staples in the form of staple sheets, in which a predetermined number of unformed staple elements are connected adjacent to one another, and a number of these staple sheets are stacked and accommodated in a generally rectangular cartridge, which is placed above the staple sheet feed path of the stapler. The stapler includes a former-driver unit and a power source for driving the former and the driver is provided by a small-sized electric motor which requires no instantaneous high consumption of electric current and generates no impact operation sound and noise, and the clinching operation of one cycle is effected by one controlled rotation of a rotating drive shaft having a speed reduced from the rotational output of the electric motor. The staple sheets are fed by providing a staple sheet feed mechanism in which an endless belt for conveying the staple sheets, including the portion for positioning the cartridge, is arranged above the staple sheet feed path and in which magnetic means for generating a suitable frictional force is interposed between the face of that endless belt and the staple sheets.
