PURPOSE:To enable the change-over of remote control sequential feed with simple constitution and low cost, by the selective operation of an electronic switch which can be selected with manual operation according to the order of a given feed of each channel by means of a remote control. CONSTITUTION:At the application of power supply, the mode of the main channel is automatically formed. When a remote control signal is fed to an input terminal 47 of remote control pulse with the remote control operation, analog switches 53, 55 are closed into a sub-shannel mode. Next, when the remote control sugnal is again incoming, the analog switches 54, 55 are closed to form the mode of main/sub- channel. Further, when the next remote control signal further comes, it is fed back to the main channel mode. Thus, the channel chage-over by the remote control operation can sequentially be made. |
