<p>PURPOSE:To control the music selection by providing a 1st time constant circuit detecting the trailing of a signal reproduced by a magnetic head and a 2nd time constant circuit detecting the leading of a reproduced signal so as to charge a capacitor being a component of the 2nd time constant circuit selectively. CONSTITUTION:The 1st time constant circuit 25 detecting the trailing of a signal reproduced by the magnetic head and the 2nd time constant circuit 30 detecting the leading of the reproducing signal are provided to apply music selection. Then not only the music selection detecting an interblock of a prescribed length provided between music recordings but also the music selection to seeking the head of the music recorded next to the long interblock is attained. Then the charging of the capacitor being a component of the 2nd time constant circuit 30 detecting the leading of the reproducing signal is blocked at the music selection by the detection of the trailing. Thus, the music selection is implemented accurately without giving any effect on the music selection by the detection of trailing.</p> |
