置。[Claims for Utility Model Registration] A channel selection control section that receives control pulses supplied from the remote control receiving system and changes the selection of multiple 71 cicadas in sequential steps, and each of the channel selection control sections. A tuning voltage generator has a potentiometer connected between the output end and the power supply, and outputs the output of the movable piece as a preset tuning voltage via a diode for preventing wraparound, and the movable piece of each switch has a potentiometer. In a television channel selection device, the mode selection section is connected to each output terminal of the channel selection control section via a wrap-around diode, and has fixed terminals connected in common to generate a tuner selection signal. Fixed terminals other than tuner selection of each switch provided in the mode selection section are commonly connected to take out a skip control signal indicating that the channel is vacant, and the channel selection control section receives the skip control signal. When responding to said tuner selection signal. A television channel selection device characterized in that it is configured to select an output end quickly and quickly select the next output end, thereby skipping an empty channel and quickly selecting a channel.
