FIG. 3 is a flowchart illustrating an operation state of the operation device 10, and FIG. 4 is a flowchart illustrating an operation state of the transmission device 25.

First, an operation state of the operating device 10 will be described with reference to FIG. Step 1 (abbreviated as S1 in the figure; the same applies hereinafter):
It is determined whether the switch 16 has been pressed. Here, if the switch 16 is pressed, the process proceeds to step 2. Step 2: The device-specific ID code stored in the ID code setting unit 11 is read, and the process proceeds to step 3. Step 3: The read ID code is converted into infrared data and transmitted, and the process proceeds to step 4.

Step 4: The control unit 18 controls the transmitting device 25
It is determined whether or not a response signal has been transmitted from. That is, at this time, the PLL unit 13 controls the front end unit 14.
Is in the receiving state of 76 MHz, and the changeover switch 23 is switched to the A side. Therefore, the response signal by the FM modulation transmitted by the transmission unit 33 as the sub-transmission means of the transmission device 25 based on the ID code transmitted by infrared rays is received by the front end unit 14 and amplified and
The signal is detected and can be detected by the control unit 18. In step 4, it is determined whether or not the response signal of 76 MHz has been received. If the response signal has been received, the process proceeds to step 5.

Step 5: Here, the control unit 18
And the identification information included in the response signal
The comparison with the ID code stored in the D code setting unit 11 is performed. As a result of this comparison, if the two pieces of identification information match, the process proceeds to step 6.

Step 6: The response signal received at 76 MHz includes the frequency switching information together with the identification information. The frequency switching information is, for example, based on the ID code emitted from the operating device 10 by an infrared signal, whether the operating device is for receiving Japanese or English is determined by the transmitting device 25 described later, Transmission device 2
From 5, frequency switching information for switching to the Japanese reception frequency (80 MHz) or the English reception frequency (81 MHz) is included in the response signal and transmitted. In step 6, based on the frequency switching information, the PLL unit 13
And the tuning frequency of the front end unit 14 is set to 80 MHz.
Switch to z or 81 MHz. At the same time as the switching of the tuning frequency, the switch 23 is switched from the contact A to the contact B.
Side. By the switching of the tuning frequency and the switching of the changeover switch 23, the operating device 10 is in a state where it can receive the audio information transmitted from the transmitting device 25.

Step 7: If voice information has been received, proceed to step 8. Step 8: While demodulating the received audio information, the demodulated audio information is amplified and detected and converted into audible audio. Thereby, the audio information transmitted from the transmission device 25 can be individually heard. Then, it proceeds to step 9. Step 9: It is determined whether or not there is an end signal in the audio information transmitted and received from the transmission device 25. When there is an end signal, the process proceeds to step 10. Alternatively, the process proceeds to step 10 when the timer 20 has received the audio information for a predetermined length. Step 10: Terminate the reception of the audio information, switch the tuning frequency of the receiving means to the original frequency (76 MHz), and return the changeover switch 23 to the A side.

Step 1: It is determined whether or not the ID code issued from the infrared transmitter 15 of the operating device 10 has been received by the infrared receiver 27, and if received, the process proceeds to step 2. Step 2: The control unit 28 determines from the received ID code whether the operating device 10 that has transmitted the ID code corresponds to Japanese or English. Then, the ID code and the information based on the frequency of the audio information to be transmitted (80 MHz or 81 MHz in this embodiment) are sent to the transmitting section 33 as the sub-transmitting means.
The above information is transmitted as a response signal at a frequency of 6 MHz.

Step 3: Following the response signal, the transmitting unit 34 or 35 is operated to transmit Japanese or English voice information at a frequency of 80 MHz or 90 MHz. In this case, a read signal is transferred from the control unit 28 to the audio information storage unit 37, and the read audio information is modulated by the PLL modulation unit 31 or 32 and transmitted via the transmission unit 34 or 35. . Then, the process proceeds to Step 4. Step 4: At the end of the voice information, an end signal is sent to the operation device 10.
To end transmission, and switch the transmission frequency to the original tuning frequency of 76 MHz.

When the timer 20 of the operating device 10 has received the audio information for a predetermined time, it sends an end signal to the transmitting device by infrared rays, or when the person operating the operating device 10 wants to stop the reception. Then, by pressing a reception end button (not shown), the infrared
, An end signal may be issued, and the transmission device 25 may stop the transmission when receiving the end signal.
