Abstract
A pivoting device for a shutter (51) is arranged in the area of the insertion opening of the loading mechanism of a magnetic-tape-cassette apparatus, which shutter is pivotable into an open position during the loading and unloading process of a magnetic-tape cassette (66), after which it resumes its closed position. The magnetic-tape cassette (66) is mechanically drawn inwards from a take-over position (E) and subsequently lowered into a play position (68) by a slide (9) with the aid of a motor drive, from which play position it is lifted and is moved to the take-over position (E) by the slide (9) during unloading. A lever arrangement (52) for the actuation of the shutter (51) is constructed in such a manner that during mechanically produced cassette movements, during which the mechanical drive is loaded to an increased extent, the lever arrangement is disengaged from the mechanical drive by an actuating rod (57). The actuating rod is actuated by the slide (9) and is movable in the insertion and the eject direction by the slide (9), and moves in the eject direction (70) during unloading and during this movement opens the shutter via a two-arm coupling lever (54). The shutter (51) is disengaged from the slide (9) during the loading process.
