Abstract

PURPOSE:To simplify the circuit constitution, by using the channel selection button having two circuits of switch mechanism at the channel selection button so that the TV reception channel selection circuit and VTR recording channel selection circuit can be directly selected interlockingly when the channel selection button is operated. CONSTITUTION:Two circuits of channel selection buttons are provided for the channel selection button section 1, and to the terminal of the section 1, the TV reception channel selection section 17 and the VTR recording channel selection circuit 18 are connected via the coincidence/noncoincidence circuit 15. To another terminal of the section 1, the channel lock switch 2 is connected and via the switch 2 and logic circuit it is connected to the terminals 17X, 18X of the sections 17, 18. The clock oscillator is connected to the terminals 17X, 18X to operate the ring counter in the sections 17, 18 according to the input level from the terminals 17X, 18X. Further, with the output of the circuits 17, 18 and 15, the TV and VTR side tuning potentiometers 36, 37 are selected so that the interlocking channel selection can be made by the operation of the button 1.
