<p>PURPOSE:To make possible restarting after automatic stopping and achieve the reduction of power consumption at the automatic stopping by separetely providing a latch circuit connected to recording-reproducing switch aside from a latch circuit connected to a fast feeding switch. CONSTITUTION:When a fast feeding switch 1 is turned ON, a supply voltage is applied to a latch circuit 47 and transistors 7, 11, 12, 34, 25, 14, 15 subsequently go ON. A motor 17 then runs and a magnet 31 runs and becomes a normal fast feed state. When the tape runs up to the final end and the reel revolutions stop, the magnet 31 also stops running and the operation of the latch circuit 47 inverts, then the motor 17 also stops. In the state where the fast feeding switch 1 has turned ON, the capacitor 43 constituting the recording-reproducing latch circuit 44 is not charged and therefore if the recording-reproducing switch 2 is turned ON, transistors 39, 28, 37, 36, 14, 15 subsequently go ON and the motor 17 may be driven.</p> |
