Stapler () which in the course of a reciprocating working stroke (V) staples a workpiece (), preferably a sheaf of papers, which stapler is powered by an electric motor which, via a transmission arrangement () drives the stapler during the working stroke, whereby the motor is activated and initiates the working stroke from a certain starting region as a result of the workpiece moving a trigger () which forms part of a trigger device () to a position at which a circuit-breaker (), which forms part of the same electrical circuit () as the motor is connected to, is closed by the trigger, and whereby a release arrangement () connected to, and operatively acted upon, by a rotating means () which forms part of the transmission arrangement moves the trigger during the return phase of the working stroke to a non-closing position at which the circuit-breaker returns to an open position, thereby breaking the electric circuit and deactivating the motor, with the result that the working stroke ends in the starting region, whereby the trigger (), when it has been moved to close the circuit-breaker () and the working stroke has been initiated by the force from a first elastic means (), remains in the position at which it closes the circuit-breaker.

Electrically powered stapler

A stapler for stapling together a workpiece, primarily a sheaf of papers, in which the stapler comprises a stapling unit and an anvil, which interacts with the stapling unit and on which the workpiece is placed, and against which stapling is performed, which stapling unit and an anvil are, driven relative to each other in a reciprocating stapling movement, during which movement stapling takes place, the stapling unit comprises a frame and a staple cassette which houses staple blanks and which is exchangeable, and which is detachably connected to the frame by attachment devices, and the staple blanks are fed one by one to an outlet channel by a feeding device incorporated in the stapler.
