PURPOSE:To automatically repeat a reproducing blank time in the shortest time, by automatically detecting the end position of the last music and the start position of the first music by a non-recording part detecting circuit, and executing the reproduction between them. CONSTITUTION:When a tape starts running at a constant speed, an output waveform of a comparing circuit, a collector waveform of a transistor, and a waveform of an output terminal of a non-recording part detecting circuit become as shown by E, F and G, respectively, and it is detected that reproduction of the last music ends. In this case, the mechanism becomes a review state. In this case, the output waveform of the comparing circuit, the collector waveform of the transistor, and the waveform of the output terminal of the comparator of the non-recording part detecting circuit become as shown by E, D and C, respectively, and the vicinity of the head of the first music is detected. Also in this case, a count value of the head of the music is recorded and the mechanism becomes a reproducing state. Subsequently, when it is detected again that reproduction of the last music ends, the mechanism becomes a rewinding state. |
