PURPOSE:To prevent a skipping phenomenon of music, by accelerating the timing of a gate signal only with a skipping action. CONSTITUTION:When a signal is supplied to a skip input terminal 12 in a reproduction mode, an output terminal 15 is set at H level. The output of an NAND circuit 7 is set at L level when a detecting signal B for reproduced sound fed from a reproducing amplifier 1 falls at the end of music. Then a counter 41 starts counting via AND circuit 42. When a soundless period is long, the signal supplied from a terminal (n) of the counter 41 is supplied to a skip music selection terminal 14 via an AND circuit 8 after a prescribed period of time. Thus a rapid traverse reproduction mode is obtained, and a skip output terminal 15 is changed to an L level. Then the counter 41 is reset via the circuits 7 and 42. In this case, an AMS output terminal 13 is set at an L level and the counter 41 starts counting again. The signal of the terminal (n) sets an FF31 of a timing control circuit 30, and therefore the generation of the gate signal shortened 30 to search a music program. This prevents a music skipping phenomenon. |
