ABSTRACT:
The invention relates to a pivoting device for a cover (7) by means of which an insertion opening (3) of a cassette holder of a magnetic-tape-cassette apparatus can be closed, which cover can be pivoted into an open position by a magnetic-tape cassette (5) during insertion thereof, in order to expose the insertion opening (3), after which it returns into its closed position, and which cover is again pivoted into the open position by the magnetic-tape cassette (5) during the outward movement thereof until the removal of the magnetic-tape cassette (5) from the cassette holder, the strip-shaped cover (7) being secured to a pivoting spindle (9) by one of its long edges (7b), which cassette holder can be lowered into a play position with the magnetic-tape cassette inserted. A sensing lever (11) is pivotable about a sensing-lever spindle (13) parallel to the pivoting spindle (9), carries a sensing element (17) to sense the upper main wall (21a) of the magnetic-tape cassette (5), and between the sensing-lever spindle (13) and the sensing element (17) carries a toothed rack meshing with a toothed wheel (25) carried by the pivoting spindle (9).
