Abstract

PURPOSE:To realize an assured repetitive selection of music with a simple constitution, by giving forcible discharge to a recorded part detecting capacitor via a transistor provided in parallel to the capacitor. CONSTITUTION:A capacitor C2 of a recorded part detecting circuit 4 is charged via input signal level deciding circuit 2, and then a recorded part is detected with discrimination from the noise, etc. to select the music. As a result, an FF5 is set via a comparator 10 to inhibit the detection of a nonrecorded part detecting circuit 3. At the same time, a transistor Q6 which is parallel to the capacitor C2 conducts. Accordingly, the capacitor C2 is forcibly discharged, and thus the FF5 is assuredly reset when a nonrecorded part is detected. As a result, an assured reset is possible to the initial state.
