Claims

[Scope of utility model registration request]

A control pulse generating means that outputs a control pulse that commands sequential channel movement in response to a channel selection operation, a counter that counts the control pulses and outputs a channel selection output that selects a channel corresponding to the counted value, and a receiver. a decoder having a plurality of channel selection output sections selected by the channel selection output, the first channel selection output section corresponding to possible channels and the second channel selection output section corresponding to unreceivable channels; a tuning type voltage generating means for generating a tuning voltage for controlling the local oscillation frequency of the tuner in the corresponding receiving channel when the first tuning output section is selected;
6 pulse generator for switching between a standby state and a non-standby state, the channel selection output or the channel selection output section being selected in response to the channel selection output only in the standby state; a pulse generator that generates a skip pulse for instructing forward channel movement in place of the control pulse according to a signal based on a channel selection output and sends it to the counter; and a pulse generator that is in a standby state only when the control pulse is supplied. A channel selection device comprising: a control circuit for controlling a channel;
