Abstract

PURPOSE:To prevent the confusion of transmission time due to the limit of maximum continous transmission time. CONSTITUTION:The time from the time when a transmission switch 20 is depressed is timed, and when the switch is operated continously before 30 seconds, a notification sound signal is transmitted. Thus, continuous transmissions over thirty seconds are notified to a reception side. In this case, when the reception side receives the notification sound signal, a transmission operation is invalidated for prescribed time over 2 seconds from a point of time and this period becomes a reception state. As a result, because this operation is invalidated even when the transmission switch 20 is erroneously depressed within prescribed time after the notification sound signal is received and the transmission switch 20 is depressed by ignorance, the transmission continuation on an opposite side can be surely notified.

At the same time when the transmission switch 20 of the transceiver A is pressed, the control unit 21 of the transceiver A sets the output terminal T 1 to "H" level. As a result, the relay 5 operates and the antenna 1 is connected to the transmitter 4 and enters the transmission state. Then, when this state is completed within 29 seconds, the operator of the transceiver B who has confirmed this state presses the transmission switch 20. That is, the operator of transceiver A
Immediately after releasing the transmission switch 20 to put it in the reception state, the operator of the transceiver B, who hears the "please", pushes the transmission switch 20 to start transmission. When the transmission switch 20 is pressed, the control unit 21 of the transceiver B is connected to the output terminal T 1

By the way, when the transmission switch 20 of the transceiver A is continuously pressed for 29 seconds, the control unit 21 of the transceiver A sets the output terminal T 4 to the "H" level for 1 second (see FIG. 2C). As a result, the relay 15 operates to connect the notification signal generation unit 14 to the transmission unit 4, and the notification signal is transmitted. When the transmitted notification signal is received by the transceiver B, it is detected by the notification signal detection unit 9 and taken into the control unit 21. When the notification signal is fetched, the control unit 21 of the transceiver B sets the output terminal T 5 to the “H” level for 1 second (see FIG. 6F). As a result, the control unit 21
Makes the buzzer 17 ring. Further, the control unit 21 of the transceiver B does not accept the operation of the transmission switch 20 for 5 seconds after the output end T 5 is set to "H". That is, the reception state is continued for 5 seconds. This is the transmission of transceiver A 3
This is to notify the operator of the transceiver B that the transmission of the transceiver A is continued by disabling the transmission of the transceiver B for 2 seconds which is temporarily stopped after 0 second and then for 3 seconds.

That is, the number of operators of transceiver A is 30
If the operator continues to talk for more than a second, the operator of the transceiver B will interfere with the transmission immediately after hearing the notification, for example, at time t indicated by the chain line in FIG. . Therefore, the operator of transceiver B is asked to give transceiver A
The operation of the transmission switch 20 is invalidated for 5 seconds in order to confirm that the transmission state is continued, and the reception state is continued. Returning to FIG. 1, the notification signal detection unit 9 corresponds to notification signal detection means. The notification signal generating section 14 corresponds to notification signal generating means. The control unit 21 corresponds to control means. In addition, the control unit 21 and the timer 16 constitute the time measuring means 100.

In the above embodiment, when the transmission exceeds 30 seconds, the buzzer sounds in 29 seconds to notify by sound, but it may be notified by an optical means such as an LED. That is, a signal for driving optical means such as an LED is sent to the other party to notify that continuous transmission is to be performed. Further, the notification may be a melody sound or a voice synthesis instead of the buzzer.
Further, in the above-described embodiment, the transmission is prohibited for 5 seconds after the notification signal is received, but the transmission invalid time is not limited to 5 seconds and may be 2 seconds or more. Further, the notification signal is transmitted when it reaches 29 seconds, but it is not limited to this, and may be 28 seconds, for example, as long as it is within the operational regulations of the Radio Law. Further, in the above-described embodiment, the notification signal is transmitted, but it is also possible to notify the transmission side operator that the notification signal has been transmitted together with the transmission of the notification signal. For example, a buzzer sound different from the buzzer sound when the notification signal is received is generated. Further, in the above embodiment, the transceiver is a single unit, but it may be applied to a wristwatch.

According to the present invention, a notification signal is transmitted before continuous transmission reaches a fixed time (30 seconds in the embodiment),
Since the receiving side is informed that the transmission will be continued even after the transmission is interrupted (in the embodiment, the transmission is interrupted for 2 seconds), it is possible to prevent the confusion state in which the mutual transmission is performed. Further, according to the present invention, since the transmission is restricted for a predetermined time from the time of receiving the notification signal at the time of reception and the reception state is continued, the transmission switch is erroneously transmitted within the predetermined time after the reception side receives the notification signal. Even if the transmission switch is pressed due to ignorance or ignorance, this operation is invalidated, so that a more confused state than the above can be prevented.
