ABSTRACT:
A magnetic-tape-cassette apparatus having a deck for magnetic-tape cassettes, which deck is constructed for playing and fast-winding operation with a first and an opposite second tape-transport direction. The deck has a first and a second selectively drivable reel disc for the magnetic tape, and a first and a second capstan adapted to be driven in different directions of rotation by a motor. A switching mechanism having a movable transport member switches the reel-disc drive from one reel disc to the other reel disc in order to change the tape-transport direction. The transport member has axially spaced toothed-rack portions which selectively cooperate with oppositely rotating toothed drive wheels for moving the transport member. The transport member is arranged to be pivotable transversely of its direction of translation in such a way that the meshing between a toothed-rack portion and a drive wheel is cancelled in the final stage of the translation movement of a tilting movement of the transport member to disengage the teeth. The tilting movement and the return into a neutral center position are obtained by a return spring which is pretensioned during the transverse movement.
