<p>PURPOSE:To prevent securely a tape from overrunning in music-selecting operation by driving a motor for driving a reel turntable in the reverse direction of the turning direction of the music-selecting operation for a certain time when the music-selecting operation is completed. CONSTITUTION:A motor driving circuit 5, when applied with an H-level signal at its 1st input terminal 5-1, drives a motor M for driving the said reel turntable at a constant speed as well as playback and recording. When the H-level signal is applied to the 2nd input terminal 5-2, the motor M is driven at a high speed as well as fast forwarding and rewinding and when an L-level signal is applied to the 3rd input terminal 5-3, the said motor M is driven normally (i.e., in fast forwarding direction). When the H-level signal is applied to the 3rd terminal, the motor M is reversed (i.e., in rewinding direction).</p> |
