Clutch arrangement provided with an automatic, double-sided asynchronous switchgear (20) wherein a central disc (21) is connected with a first connection point and each side of the switchgear (20) is connected, through free-wheels (30, 40), with another connection point, the locking directions of the free-wheels (30, 40) being counter to each other. When using the arrangement in a magnetic tape recorder and/or playback unit, the first connection point is connectible to one of the spindles (3), the second connection point to the frame (2) and the third connection point to the driving motor.

Clutch arrangement, mainly for driving the tape-spindle of magnetic tape

A tape-conveying system for forward and backward playing magnetic tape recorder and/or playback unit is disclosed a motor (19) driving the magnetic tape (8) at the required speed, a sound shaft (2) interconnected with the motor (19) and fixed through a bearing to a frame (1), a device transmitting movement of the sound shaft (2) to the magnetic tape (8) form a drive mechanism, two winding shafts (4, 5), tape-spindles (6, 7) placed on said winding shafts (4, 5) and winding and unwinding mechanisms connected with the winding shafts, these mechanisms being asynchronous winding clutches (22, 23) and asynchronous unwinding clutches (20, 21) are included in the system. The clothes are interconnected with each winding shaft (4, 5), with the other side of the winding clutches (22, 23) is connected with the driving motor (19). The other side of the unwinding clutches (20, 21) connected with the frame (1), and only one of said connections functions simultaneously on the same winding shaft (4 or 5). With respect of the other winding shaft (5 or 4) the connections are reversed compared with that of the first winding shaft (4 or 5).
