Abstract

PURPOSE:To realize a low cost for the channel selecting device, by always shifting the channel selecting position of the channel selection part at the VTR side so as not to correspond to either channel selection switch of the TV when the VTR starts the reproducing action in the TV picure receiver incorporating the VTR. CONSTITUTION:The channel selecting device consists of channel CH selection SW part 20 comprising plural units of self-release type switches SW, channel selection parts 17a and 17b forming the TV-side and VTR-side series each, tuning voltage output circuits 18a and 18b, electronic tuners 8a and 8b, defeat D amplifying circuits 6a and 6b, shut-off circuit 15, reproducing time channel selecting circuit 19 and others. And in case the broadcast of the selected CH is received under the reproduc- ing action of VTR14, signal D sent from circuit 6b is applied to circuit 15 to secure the AND with the reproduction mode signal sent from VTR14 and then to be applied to VTR14. Thus the reproduction mode is cancelled. And in case the selected CH is equal to the previous CH, the reproduction mode signal from VTR14 is applied to circuit 19 to secure the operation of circuit 19 for a fixed time. And the selecting action is started for the channel selecting position of part 17b by the output of circuit 19. Then the cancelling is given as stated above.
