<p>PURPOSE:To make it unnecessary to wait for coming of a sensing tape after the end of music by providing a switching circuit which sets the fast forwarding state when music is terminated. CONSTITUTION:The signal reproduced by a reproducing head 1 is properly amplified by an equalizer amplifier 2, and the output is inputted to a comparator 3, and the end of music is discriminated to output the output. Since differentiating circuits 7 and 8 operate a switching transistor TR for fast forwarding only when the voltage of the output of the comparator 3 rises at the end of music, a discharging circuit 9 is required for quick discharging like repetitive operation. The switching transistor for fast forwarding is turned on by the music end signal to set the same state as depression of a fast forward button 11, and the fast forwarding state is set. An inhibiting output 14 is outputted after reproducing of an 8-track player control circuit 13 and resets the comparator 3 to prevent the malfunction.</p> |
