<p>PURPOSE:To execute intermusic detection by a simple constitution, by adding a resistance and a capacitor for setting a recovery time, to an A/D converter for converting a reproducing signal to a signal for driving a level indicator. CONSTITUTION:A resistance R and a capacitor C, which have been added to a level meter circuit 10 are used for giving a recovery time to a signal applied to terminals 14, 15, and these resistance R and capacitor C are set to such a value that the length of intermusic can be detected by the recovery time. Therefore, unless a signal is inputted until the recovery time passes after the tape has reached intermusic and the signal applied to the terminals 14, 15 has been broken, a plunger driving circuit 13 is driven, a plunger is driven, and running of the tape is stopped. In this way, it is possible to detect intermusic by a simple circuit configuration.</p> |
