It is selected and output in 04 and is output as audio through the AF signal amplification unit 106 and the speakers 107a to 107n.

Reception of roadside radio broadcasting will be described below. When receiving this roadside radio broadcast, first, the time setting unit 10 is operated from the operation unit 114 through the operation control unit 113.
The reception start time and end time are set in 9. As the reception start time and the end time, for example, since the traffic information is broadcast for about 30 minutes from the determined time every day, a plurality of times and times corresponding to the plurality of broadcasts are set. Further, the frequency (station) of the roadside radio broadcast to be received is set in the reception frequency setting unit 110 from the operation unit 114 through the operation control unit 113. As the reception frequency of this roadside radio broadcast, for example, a plurality of frequencies 1620 kHz or 1629 kHz is set. After this setting, the time setting unit 109, when the set reception start time comes, the tuner 102, the voice recording / reproducing unit 108, and the reception frequency setting unit 1
Instruct to activate 10. That is, the tuner 102 receives a frequency band (AM / FM) to receive a roadside radio broadcast.

The information of 629 kHz) is sent to the tuner 102. The tuner 102 receives the roadside radio broadcast based on the frequency, time, and time information, and outputs the tuner output signal S103 to the voice recording / playback unit 108. The voice recording / playback unit 108 erases the previous recording, starts recording the roadside radio broadcast (tuner output signal S103) received this time, and ends the recording when the roadside radio broadcast ends. For example, since the broadcast time of traffic information is often about 3 minutes, a solid-state storage element (memory) capable of recording at this time is used. When the AF source selection unit 104 selects the AF signals of L and R from the CD during this recording, the CD reproduction is continued. Also, the tuner 10
When the tuner output signal S103 from 2 is receiving a broadcast other than the roadside radio broadcast selected by the AF source selection unit 104, the recording operation in the audio recording / playback unit 108 is stopped as an exceptional process. Further, when the tuner 102 is receiving a broadcast other than a roadside radio broadcast, the reception frequency is forcibly switched to the reception frequency from the reception frequency setting unit 110. At the same time as instructing the voice recording / playback unit 108 to start this recording, the time storage unit 111 is also instructed to store the time when the current roadside radio broadcast was received.
In this way, the roadside radio broadcasts in a plurality of time zones are sequentially recorded and the time is stored. In this case, by deleting the recording and time of the previous roadside radio broadcast, the latest recording and time of the roadside radio broadcast can always be obtained.

In this way, the roadside radio broadcast is automatically recorded, the time is further stored, and then the recording is automatically and sequentially performed by the AF source selection unit 104 and the AF signal amplification unit 106.
And the speakers 107a to 107n. Further, the time is displayed on the screen of the display unit 112. Further, manual reproduction and display instructed from the operation unit 114 for the automatic reproduction and display are performed. In this case, when the manual reproduction is instructed from the operation unit 114, the operation control unit 113 instructs the voice recording / reproducing unit 108, the time storage unit 111, and the AF source selecting unit 104 to transmit the roadside radio broadcast from the voice recording / reproducing unit 108. Playback is performed through the AF source selection unit 104, the AF signal amplification unit 106, and the speakers 107a to 107n. At the same time, the stored time is read from the time storage unit 111 and sent to the display unit 112.

As a result, a plurality of set times (time zones)
Since the roadside radio broadcasts are sequentially recorded, the time is stored and played back, and the time is displayed on the screen, the service area is not noticed on the highway as in the conventional example. Even if you pass through or start listening, the service area will not end and you will not hear and leak roadside radio broadcasts. Also, since it is possible to know the time when the roadside radio broadcast was performed, for example,
In the case of traffic congestion information, it becomes possible to estimate the current traffic congestion situation from that time. When the time setting unit 109 has reached the reception start time, the operation control unit 11
3 is interrupted, and the operation control unit 113 controls the reproduction of the roadside radio broadcast by the manual setting to be interrupted so that the latest roadside radio broadcast is always recorded and the time is stored.

When the reception start time arrives at the time setting unit 109, the display unit 112 is instructed to display on the screen that a new roadside radio broadcast has been received. Thereby, for example, when the user leaves the vehicle equipped with the radio receiving apparatus, it becomes possible to quickly find out that a new roadside radio broadcast has been received thereafter. It should be noted that the fact that this new roadside radio broadcast has been received is displayed on the screen, and the AF signal amplifier 106 is controlled to control the speaker 107.
It is also possible to output a sound from a ... 107n, for example, a continuous beep sound. Moreover, you may make it notify by light, such as a light emitting diode (LED).
