<p>PURPOSE:To provide a music selecting device without malfunction caused by the winding position of a tape by counting a number of revolution a reel base from the time of detecting the begining of music to its stoppage after detecting the begining of the music and stopping it in accordance with the counted result after reversely rotating. CONSTITUTION:A level meter circuit 8 detects the signal level of a sound signal outputted from a level adjusting circuit 3. The detected signal of the level adjusting circuit 3 is converted to digital data by means of an A/D converter circuit. A rotation detecting sensor 7 detects the rotation of the reel base. A music selecting control circuit 10 decides the begining of music of the reproduced sound signal reproduced from the digital data of the A/D converter circuit 9, counts the pulses of the rotating sensor 7 and controls a mechanism control circuit 6 and a muting circuit 4.</p> |
