Hand-operated tacker

The present invention relates to a hand-held fastener driving tool (10) for fastening elements (130) having a drive assembly (30) for a driving ram (13), with a trigger switch (19) for triggering a driving operation by means of the drive arrangement (30) and with a displaceable on a mouth part (16) arranged Anpressfuhler (18) via which the pressing against a workpiece (W) is detectable and in a starting position (41) prevents the triggering of a driving operation and in a shift position (43) is a triggering of a driving operation made possible. To improve the driving tool a displaceable at the mouth portion (16) is provided arranged elements sensor (17) which is independent of the Anpressfuhler (18) operable for preventing in a starting position (42) the triggering of a driving operation and in a shift position (44) the triggering a driving operation enables, wherein on the element sensor (17), the attaching a construction auxiliary member (110) on the muzzle part (16) is detectable, and wherein a driving operation on the trigger switch (19) only is triggered when both of the elements probe ( 17) as well as the Anspressfuhler (18) in its respective switching position (43, located 44).
