Abstract

PURPOSE:To enable to detect the specific signal simply without malfunction, by discriminating the specific signal inputted within a given time range for the specific or virtual signal through the check of number of times of the signal. CONSTITUTION:The signal recorded on the magnetic sheet 1 is picked up with the magnetic head 2, and normal signal such as audio and music is outputted from the speaker 11 via the preamplifier 3, gate circuit 9 and main amplifier 10. On the other hand, the stop control signal is fed to the FC detector after being arranged into almost a given signal level via the amplifier 3 and AGC circuit 4. The detector 5 performs pick up of the control signal and wave shape to obtain the pulse train produced with equal period as an output. The counter 6 performs count for the number of pulses within a given time range, and when it is confirmed that it is normal stop signal, the stop control signal is outputted as the terminal 7. The monostable multivibrator 8 is operated with the signal at the terminal 7 and the gate circuit 9 is closed, allowing to stop the output from the speaker 11 after the confirmation of the stop signal.
