<p>PURPOSE:To retrieve a desired piece of music easily by reproducing only the beginning parts of pieces of music successively by detecting no-signal parts of a tape by high-speed retrieveal and by performing reproduction only for time set to a counter circuit while performing the high-seed retrieval again. CONSTITUTION:With the output signal of an operation button 9 for normal- directional high-speed retrieval, storage circuits 13 and 15 are operated through OR circuits 12, 14 and 16 and their outputs are outputted to the input terminals CUE and REVEW of a mode control circuit 1 through OR circuits 18 and 20. To one input of an AND circuit 34, the output of an OR circuit 35 is supplied and to the other, the output of a detecting circuit 31 which detects the no-signal part of a tape 32 is supplied; and the output of the circuit 34 is sent to the input terminal PLAY of the circuit 1 through an OR circuit 11 to reproduce music. Simultaneously, a storage circuit 30 is operated by the output of the circuit 34 to input the output of the circuit 30 to one terminal of an AND circuit 24 and a clock signal to the other terminal, and the output of the AND circuit 24 is inputted to the clock input terminal of a counter circuit 23. While a set count number is counted by the circuit 23, a reproduction state is set and after the counting, high-speed retrieval is started again by its output.</p> |
