送話器２５による通話を可能とする。(Prior art) An example of a car telephone device, which is a conventional wireless telephone device, is shown in the second example.
As shown in the figure. The car telephone device shown here is roughly divided into a transceiver unit 1 and a control unit 2. The transceiver unit 1 is generally installed in the trunk of a car, and the control unit 2
is installed inside the passenger seat. Transceiver unit 1
is the necessary power supply voltage Vcc that receives the voltage from battery 3
A power supply section 11 that generates 1°V cc2, a control section 12, a radio section 13, an audio section 14, a battery 3, and a power supply section 11.
The power line switch 15 is provided between the power line switch 15 and the power line switch 15. The control unit 2 also includes a keypad 21 for inputting dial numbers, etc., a control section 22, and a receiver 2.
4, the control unit 1 is composed of a transmitter 25, a speaker 26 for ring tone/light main, and a power key human power detection circuit 27. A communication path is formed between the mobile phone and other car telephone devices, and communication using the handset 24 and the transmitter 25 is possible.

Use one of the keys in 1 as a power switch, and if you keep pressing this key for a predetermined time, the power key human power detection circuit 2
7 detects this and turns on the power line switch 15 in the transceiver unit 1. Furthermore, when the key is pressed again for a predetermined period of time, the power key human power detection circuit 27 detects this and turns off the power line switch 15 this time.
つまり、電源スイッチの機能を割当てたキーを所定時間
だけオン操作するたびに電源ラインスイッチ１５をオン
状態とオフ状態に交互に切換える構成である。That is, the configuration is such that the power line switch 15 is alternately switched between the on state and the off state each time a key to which the power switch function is assigned is turned on for a predetermined period of time.

通話路が切断されてしまうという問題があった。(Problem that Akira is trying to solve) By the way, since the control unit 2 has a built-in handset, the user has to hold the control unit 2 in his hand while talking. . For this reason, during a call, you may accidentally press the key on the keypad 21 that is used as a power switch, and the Vi device may be unexpectedly turned off and the call path may be disconnected even though the call is in progress. There was a problem with this.
