<p>PURPOSE:To easily make a change in mode by providing a motor which rotates in both directions to move forth and back a head support plate in addition to a motor for driving a tape, and allowing an electronic control circuit to limit the turning direction and time of the motor. CONSTITUTION:The electronic control circuit outputs a signal for controlling the rotation of the motor 61 by mode changing operation and als outputs a signal which rotates the motor normally and then by a gear 67 for mode transition normally by a half when a change from a stop mode to a normal playback mode is made. Further, the circuit outputs a signal which reverses the motor 61 and turns the gear 67 backward by a half when a change from the normal playback mode to the stop mode is made. When a change from the normal playback mode to a reverse playback mode is made, on the other hand, the circuit outpus a signal which rotates the motor 61 normally and rotates the gear 67 normally by one turn. Thus, the control circuit is formed into an IC to attain size reduction.</p> |
