Trigger mechanism for an electromechanical actuator for operating a desk stapler

Abstract From the Canadian patent

An electromechanical actuator device for operating a desk stapler, which has a trigger mechanism comprising a movable assembly selectively positionable in the casing of the electromechanical actuator device in the region of the zone of application of the metal staples. The said movable assembly has a pivotable striker projecting into the slot for introduction of the sheets so as to be contacted thereby and pivoted upon the Introduction of sheets to be stapled, such pivoting movement bringing a part of the striker into operating contact with the operating arms of a microswitch so as to initiate operation of the electromechanical actuator device.
