The operating device 2 inputs frequency information from the first traffic information station signal area 50 or the second traffic information station signal area 51 in accordance with the operation time of the traffic information station selection button 20, and sends the traffic information of the frequency to the receiving circuit 1. The station is configured to be received. When the traffic information station selection button 20 is operated during reception of a normal broadcast station, the operation device 2 displays the state of the receiver at that time, for example, if a normal broadcast is being received, the broadcast station information being received is displayed. It is configured to be saved in the stack area 55 of the memory 5 and stored. If the traffic information station selection button 20 is operated for a predetermined time while receiving one traffic information station, the mode is switched to reception of the other traffic information station. It is configured to call out the information of the initial state from 55 and return to the initial state. Also, when another key or operation button of the operation device 2 is operated during reception at the traffic information station, the initial state information is called from the stack area 55 and the operation is returned to the initial state.

Further, when the traffic information station selection button 20 is operated for a predetermined time, the operation device 2 is configured to generate a guide tone to that effect from the speaker of the receiver body.

In the above, the configuration in the case where the number of traffic information stations is two is shown, but the number of stations may be two or more. It is also possible to adopt a configuration in which not only a traffic information station but also a plurality of ordinary broadcasting stations are selected by operating a single button.

 The operation will be described with reference to FIG.
