<p>PURPOSE:To enable searching of musics accurately despite short intermusic intervals by leading out the counter signal of tape and intermusic interval detecting signal and storing the count value of the counter at the leading-out of the intermusic interval detecting signal thereby controlling tape running. CONSTITUTION:A Hall element 8 is provided in proximity to the ring magnet 5 provided to a take-up reel 5 and the output of this element 8 is counted as alpha signal. When the end of a music is reached, the intermusic interval signal is drawn out from a magnetic head 7 in an intermusic interval detecting circuit 10 to provide the beta signal. These are supplied to a microcomputer to perform high speed stopping and reproduction run controlling. Hence, the count scale of the counter at the time when the end of the music is reached and the stop signal beta is generated has beforehand been stored and the portion having been overun is fed back by reversing the motor revolutions then stopping the motor, thus the searching of the next music may be accurately performed even if the intermusic intervals are short.</p> |
