IPC: G11B15/087
Filed: 1980-07-18
Abstract: PURPOSE:To obtain an intermusic detecting circuit that can assurely perform a music selection to be repeated, by discharging the capacity charge based on the detection and by utilizing the output of detection signal. CONSTITUTION:When an input signal level deciding circuit 2 detects a recorded part, a capacitor C2 of the 1st detecting circuit 4 is charged. Thus an FF5 is set and a nonrecorded part detecting circuit 3 is turned active. Then the nonrecorded part is detected by the circuit 3 due to a reduction of input level and via the circuit 2, and thus a monostable multivibrator 7 is triggered. And the output of the monostable multivibrator 7 is turned into the intermusic detection signal. At the same time, a transistor Q6 is turned on by the output of the monostable multivibrator 7. Thus the electric charge of the capacitor C2 is discharged. Thus the initial state is assuredly restored, and accordingly an intermusic detecting circuit can give an assured action to the music selection to be repeated.
