Abstract
A magnetic-tape-cassette apparatus constructed for play and fast winding operation with a first and an opposite second tape transport direction, for which purpose there are provided, in addition to a first and a second reel disc (12a, 12b) for the magnetic tape, which can be driven selectively by a reel-drive mechanism (09), a first and a second capstan (3) which can be driven in opposite directions of rotation, the reel-drive mechanism (09) comprising in the transmission path between a unidirectional motor (23) and the reel discs (12a, 12b) a play coupling which is driven by the motor (23) and which comprises a primary coupling wheel (9) and a secondary coupling wheel (10), the secondary coupling wheel (10) driving the forward reel disc (12a) in the forward play direction via a pivotal mechanism (16, 17) which is pivotable supported on a switching lever (29), and the secondary coupling wheel (10), which is constantly in mesh with a reversing wheel (15), driving the reverse reel disc (12b) for the reverse winding direction via the pivotal mechanism (029) which is applied to the reversing wheel (15) by the switching lever (29).
