Abstract: A battery-operated screwdriver, having a housing (12, 18) with a handle (14), in particular bent at an angle like a pistol grip, with a preferably fixedly installed rechargeable battery (40), and with charge contact tongues (37) for charging the battery (40) on a charger shell (22), is always ready for use and available by quick, simple access to the tool insert and screwdriver bit, because its battery (40) is designed as a lithium ion cell (Li ion cell) and can be placed in a chronologically undefined way, particularly in intervals between uses, on a charger shell (22), and the charging mode can be produced automatically, and the charger shell (22) has a detachably securable, magazinelike bit holder (99), with a plurality of compartments into which screwdriver bits (20) can be inserted.

Abstract: A marking device, in particular a hand-held marking tool for positioning markings, comprises first means (50, 52, 54, 56) which make it possible to position the device (10) in a predefinable first position of a reference surface (16), and second means (46) for leveling the device (10) relative to the reference surface (16), as well as a tracking system (13) for determining a distance covered by the device (10) relative to the first position of the device. The tracking system (13) detects the movement of the measuring instrument (10) on the reference surface (16) in two orthogonal directions (18,20).
