Claims

[Scope of utility model registration request]

a tuning mechanism that moves in a predetermined search frequency band; an edge detection means that detects an edge of the search frequency band of the tuning mechanism;
reception detection means for detecting that a specific broadcasting station in the frequency band is being received; a micromolecule stage for differentiating the output of the reception detection means to detect reception loss; a memory means whose memory is set when the detection is detected and whose memory is reset by the output of the differentiating means; a gate means which stops the output of the reception detecting means when there is an output of the memory means; An automatic channel selection device including a control unit that drives a channel selection mechanism.
