PURPOSE:To listen to traffic information, earthquake information, etc., conveniently by detecting a desired discrimination signal, transferring channel selection information on the switching of a channel selecting circuit or the other channel selecting circuit to one channel selecting circuit, and automatically listening to a desired broadcast program. CONSTITUTION:When there are plural discrimination signals for a broadcast band, a discrimination signal detecting circuit I/DET detects one discrimination signal through a control circuit CONT by the designation of a listener. When the designated discrimination signal is detected, the circuit CONT stops the sweeping operation of the other tuner circuit TUNER2 immediately and controls a switch SW to perform switching to the listening of a broadcast program including a discrimination signal received by the other circuit TUNER2. When the discrimination signal is ceased by the ending of the broadcast program, the circuit CONT controls the switch SW to perform switching to normal broadcast reception by one circuit TUNER1. |
