Abstract

PURPOSE: To realize multi-function program searching circuit with a simple constitution, by effectively processing the pulse signal for system control relation.
CONSTITUTION: The temporary stop signal forming circuit 5 and the TV channel selection signal forming circuit 6 are connected to the relay 4 between the program searching signal generator 1 and the recording head 4 via the OR circuit 7, delay circuit 8, inversion circuit 9, AND circuit 10, and drive circuit 11, and the AND circuit 10 is connected to the program searching switch 17. Thus, at temporary stop mode, and at TV channel selection, the relay 3 is driven with the drive circuit 11, and the output of the program searching signal generator 1 is reocrded on tape with the recording head 4. Further, at fast feed and rewinding, the recording signal is reproduced with the program searching reproducing head 12, and after amplification 13 and detection 14, the stop solenoid 16 is driven via the drive circuit 15 and stopped.
