FIG. 1 shows a block diagram of a transceiver. (1) is a control circuit composed of a microcomputer, which controls the whole according to a control program in a built-in program memory. (2) is a receiving circuit for receiving a transmission signal from another transceiver, and the received call signal is supplied to an audio circuit (3) and reproduced through a speaker (4). (5) is a transmission circuit for transmitting to another transceiver, and inputs and transmits a voice signal from the microphone (6) and a call signal from a call signal circuit (11) to be described later via the sound circuit (3). The transmission circuit (5) is controlled by the control circuit (1) so as to be in an operating state only when transmitting. (7) sends the local oscillation signal corresponding to the channel number data from the control circuit (1) to the receiving circuit (2),
A PLL synthesizer circuit that similarly provides a transmission carrier signal to a transmission circuit (5). (8) is a transmission / reception channel setting switch composed of a rotary switch.
9 channels can be set. The control circuit (1) outputs the channel number data based on the setting of the switch (8). (9) is an automatic reset type talk switch, and when OFF, the control circuit (1) is a transmission circuit (6)
And controls the PLL synthesizer circuit (8) so that the receiving circuit (2) tunes to a predetermined channel,
When it is ON, the control circuit (1) deactivates the receiving circuit (2) and controls the PLL synthesizer circuit (8) so that the transmitting circuit (6) transmits on a predetermined channel. (10) is an automatic return type call switch. When the talk switch (9) is turned on and turned on, the control circuit (1) drives the call signal circuit (11).
The calling signal from the calling signal circuit (11) is supplied to the speaker via the audio circuit (3) to notify the operator that the calling is being performed.

First, when two users having the transceiver of the present invention talk with each other, for example, the transmission / reception channel setting switches (8) of both transceivers are set to five channels (this channel is predetermined between the users). Shall be). In this state, when the power is turned on and the talk switch (9) is operated, the control circuit (1) drives the calling signal circuit (11) for 5 seconds to call the other party (steps S-1, 2). Thereafter, if the other party answers, the call can be made by the same call operation as before. However, according to the present invention, when the operation of the talk switch (9) is released, the control circuit (1) starts the timer operation and determines whether the operation of the talk switch (9) again is within 3 minutes after the release. If it is less than 3 minutes, it is determined that the call is ongoing and the calling signal circuit (11) is not driven, and if it exceeds 3 minutes, the calling signal circuit (11) is driven for 5 seconds as described above ( Steps S-3 to 5, 11, 1, and 2). In other words, in a normal operation state, only the talk switch (9) is called,

る。According to the present invention having the above-described structure, if the operation of the talk switch is within a predetermined time after the end of the communication, the transmission of the calling signal is regarded as a continuous call, and the transmission of the calling signal is prohibited. After the elapse, a call signal is transmitted for a predetermined time, and in a normal use state, a call can be made only by operating the talk switch, and a call can be made.
