<p>PURPOSE:To detect a non-recording part correctly to transfer it to the reproducing state, and to generate a reproducing sound after almost a constant time, by generating a detected output different at the starting time point of a reproducing signal with that after a prescribed time elapsed from the end time point. CONSTITUTION:An output at an output terminal 10b of a signal detection circuit 10 detects the start part of a signal section 15, sets the mode to a rewinding reproducing state and switches the mode into the reproduction. After a time T via the non-recording 14 from the signal part 15, a pulse rising waveform is outputted to the output terminal 10b. The start part of the signal section 15 is detected and the mechanism is changed into the stop mode. When a pulse is outputted after the signal at an input terminal 10a is lost, a pulse is outputted after the time T, the mode is switched into the rewinding reproducing mode automatically via the stop mode after a prescribed time, and when the time T is elapsed after the rewinding reproducing output is finished, the pulse rising waveform is outputted and the mode is switched into the reproducing state.</p> |
