という欠点がある。In the above-mentioned conventional car phone device, since there is a difference in the reset voltage of both reset circuits 3.8, when the power supply voltage drops to a certain value, only one is reset and only one is initialized. There is a drawback that an abnormality occurs in the overall operation, and as shown in FIG.
When trying to supply a reset signal from the reset circuit 3 of the mobile phone 22 to the reset circuit 8 of the telephone 22, there is no space in the curl cord 13 that connects the mobile device main body 11 and the telephone 21, so one signal line (signal line 10) is added. There is a drawback that it must be done.

。The mobile phone device of the present invention has an oscillator in the mobile device main body, which has an oscillation frequency that can be distinguished from the frequency used for exchanging data in the signal line between the mobile device main body and the telephone device,
When the reset circuit of the main body of the mobile device is activated, when the oscillation frequency of the oscillator sent through the signal line is detected, the reset circuit of the telephone is activated. A detection circuit is included in the phone.
次に、本発明の実施例について図面を参照して説明する
。Next, embodiments of the present invention will be described with reference to the drawings.

。The reset circuit 3.8 is the same as the conventional one shown in FIGS. 2 and 3. The signal line 9 is used for exchanging data between the mobile device body 1 and the telephone set 2, and is a line within the curl cord 13. Here, two oscillators 4 whose frequencies used for this data exchange are, for example, 1.2 KHz and 1.8 KHz, oscillate at a frequency of 3 KH2 when the reset circuit 3 operates. The switch 5 closes when the reset circuit 3 operates, and sends the signal from the oscillator 4 to the signal line 9. On the other hand, the telephone M12 includes a filter 6 that detects the signal from the oscillator 5 sent through the signal line 9 and is set to the aforementioned 3KHz frequency, and a reset circuit 8 that detects the output voltage of the filter 6. The rectifier 7 that operates the signal line 9
It is provided in parallel with a circuit (not shown) connected to.

動作する。Next, the operation of this embodiment will be explained. When the reset circuit 3 of the mobile device main unit operates, the 1 oscillator 4 emits 3 KH.
A signal with a frequency of z is sent to the telephone 2 via the switch 5 and the signal line 9. Then, this signal is detected by the filter 6, the output voltage is detected by the rectifier 7, and the reset circuit 8 is operated.

電話機２にリセットがかかってしまうことはない。As described above, the mobile device main body 1 and the telephone 2 are initialized at the same time. Note that since the frequency of the oscillator 4 is set to a frequency that can be distinguished from the frequency used for exchanging data, the telephone 2 will not be reset when data is transmitted from the mobile device body 1 to the telephone 2.

By operating the reset circuit of the telephone from the reset circuit of the mobile device with a signal of a frequency that can be distinguished from the frequency used for data exchange, the mobile device and the telephone can be put into a reset state at the same time without increasing the number of signal lines. There is an effect that can be done.
