Return the receiver to operating condition. Thereby, the receiving device can be returned to its original state without performing any new operations.

<Example> An embodiment of the present invention will be described below based on the drawings.

In FIG. 1, the AM receiving section 5 and the FM
The receiving section 6 and the cassette deck section 7 are controlled by a control device 1 mainly composed of a microcomputer, and are configured to receive broadcasting at a predetermined frequency and convert it into audio through a speaker 9 via an audio circuit 8. ing. Further, the cassette tape is played back in the cassette deck section 7 and similarly converted into audio by the speaker 9 via the audio circuit 8.

The control device 1 has an operating section 3, and by operating the operating section 3, an operator performs various operations on the receiving device. The operation unit 3 is equipped with a traffic information station selection button 4, and by operating this traffic information station selection button 4, it is possible to cause the AM reception unit 5 to receive a predetermined traffic information station. It is configured as follows. .

The control device 1 has a memory 2, and is configured so that the state of the receiving device can be stored in the memory 2 when the AM receiving section 5 receives traffic information information. The control device 1 further includes a power source 10, which also controls on/off of the receiving device.

The control device 1 has a control section for a receiving device, and also has a traffic information station selection section 11 and a return section 12. When the traffic information station selection button 4 is operated, the traffic information station selection section 11 controls the AM reception section 5 to select the traffic information station and perform reception.

At the time of reception, this embodiment is configured to seek the frequency on which traffic information is being provided and receive that frequency. Conventional devices can only receive one traffic information station that has been preset in advance, and in order to receive traffic information stations on other frequencies, it is necessary to re-preset the frequency to that frequency, and this embodiment eliminates this drawback. This is an improved version of .

When the control device 1 causes the AM receiving section 5 to receive traffic information information, the control device 1 causes the memory 2 to store the state of the receiving device. That is, if the receiving device is off, it is configured to memorize the fact that it is off, and if the receiving device is in reception by the AM receiving section 5 or FM receiving section 6, it is configured to memorize the receiving frequency. or,
If the cassette deck section 7 is in operation, it is configured to store its operating state.

The control device 1 operates when the traffic information station selection section 11 does not select a traffic information station, that is, when the traffic information station does not broadcast traffic information, or after a predetermined period of time has elapsed after receiving the traffic information station. It is configured to operate the return unit 12 to return the receiving device to the operating state stored in the memory 2 before receiving the traffic information station. That is, if the receiving device is off before receiving traffic information, the receiving device is turned off, and the AM receiving section 5,
If the FM receiving section 6 is receiving a predetermined broadcast, it returns to receiving that frequency. Further, if the cassette deck section 7 is in operation, the operation of the cassette deck section 7 is restored. Further, when the traffic information station selection button 4 is operated twice, the control device 1 continues to receive the traffic information station even if a predetermined time has elapsed as a traffic information station receiver, and when necessary, the traffic information station reception function continues to receive the traffic information station. It is configured so that it can continue to receive stations.

Next, the operation of the traffic information station selection device will be explained based on FIG.

The control device 1 constantly checks whether the traffic information station selection button 4 has been operated or not (Step 2o).

When the traffic information station selection button 4 is operated, the current operating state of the receiving device is stored in the memory 2 (step 21).
). Then, the seek operation is started (step 22), the frequency of the traffic information station is sequentially sought, the broadcast is stopped at a certain frequency, and that frequency is received (steps 23, 24).
25). When receiving data, a timer is set (step 26) 6. If the traffic information station is not broadcasting even after scanning all frequencies, the operating state stored in the memory 2 is read out and the return unit 12 is activated. and return the receiving device to the operating state immediately before receiving the traffic information station (step 30).
.

While receiving the traffic information station, it is checked whether the traffic information station selection button 4 has been pressed again (step 27), and whether the predetermined time set in the timer has elapsed (steps 27 and 28). . After a predetermined period of time has elapsed, the operating state stored in the memory 2 is read out and the return unit 12 is activated to return the receiving device to the operating state immediately before the traffic information station reception (step 30).

When it is detected in step 27 that the traffic information station selection button 4 has been operated again, the operation of the timer is stopped and reception of the traffic information station currently being received is continued. Thereby, if the user wants to continue receiving the traffic information station, he or she can continue receiving the traffic information station by operating the traffic information station selection button 4 twice.

The flowchart shown in FIG. 3 has step 31 added after step 29, and by operating any button or switch on the operation unit 3 while continuously receiving the traffic information station, the operation before receiving the traffic information station can be performed. It is designed so that it can immediately return to its original state.

As described above, with the above configuration, when there is no broadcast from the traffic information station, or when a predetermined period of time has elapsed after receiving the traffic information station, the receiving device can automatically return to the operating state immediately before receiving the traffic information station. It is also possible to continue receiving traffic information stations by operating the traffic information station selection button 4 twice.

Further, even when there are many frequencies of traffic information stations, since each frequency is sought in sequence, the traffic information stations can be reliably received. Furthermore, in the case of the embodiment shown in FIG. 3, the receiver can be easily returned to the state before receiving the traffic information station while continuously receiving the traffic information station.

<Effects of the Invention> As explained above, the receiving device equipped with the traffic information station selection device of the present invention has a traffic information station selection means and an operating state of the reception device immediately before the traffic information station selection means operates. means for detecting that the traffic information bureau is not conducting traffic information broadcasting and returning the receiving device to the operating state stored in the storing means; and after a predetermined time after receiving the traffic information broadcast. Since the receiving device has a means for returning to the memorized operating state of the receiving device, it is possible to automatically return to the operating state before receiving the information from the traffic information station, which conventionally required a complicated operation. . Therefore, there is an effect that the operation of the receiving device when receiving information from the traffic information station becomes extremely simple.
