Since this invention is configured as described above,
If the reception band or reception frequency is changed, it is equivalently assumed that the end signal has been received, and the program identification reception is reset. Therefore, for example, in a car-mounted system, if the car enters a tunnel or the like and fails to receive the end signal of the program and an unwanted program is played, by operating the receiver's tuning knob (not shown), It is possible to switch to the playback mode of other music sources, and the tuning knob, band selection switch, etc. can have two types of functions.
