ABSTRACT:
An electro-magnetic tacker, which can carry out a limited number of driving strokes when its main switch is actuated, has a staple magazine pivotal between a blocking position and an operating position. In the operating position of the staple magazine, a staple blocking member blocks the front staple located in the staple magazine and, in the blocking position of the staple magazine, releases this staple for entry into a staple output channel. A coupling element connected to the staple magazine has an engagement portion which, in the switched-on position of an actuator element of the main switch, is in engagement with this. In this switched-on position, the actuator element holds the staple magazine in the operating position via the coupling element, so that the tacker can be lifted off from a workpiece, while at the same time the operating position of the staple magazine and the blocking action of the staple blocking member are maintained.
