The control circuit 70 is in the stationary mode. Therefore, the DC power is not supplied from the output 806 of the power supply circuit 68 to the communication block 76.

At this time, the switch 10P, 10
When one of the S, 10E and 18M switches is turned on, the input 82 of the flip-flop circuit 78 connected to it is
The potentials of P, 82S, 82E and 82M change from high level to low level. For example, if switch 18M is turned on,
The input 82M of the flip-flop circuit 78 becomes low level, and its output 808M is inverted from low level to high level state. When the input 808M goes high, the NOR circuit 80 puts its output 810 into a low level. Control circuit
When 70 detects the low level state appearing on its connecting line 810, it shifts this control circuit 70 to the operating mode state.

The operation of the control circuit 70 will be described in detail. In step 1000 shown in FIG. 10, the mode control section 900 of the control circuit 70 detects when the output 810 of the operation block 74 becomes low level and detects this. The operation mode of each part of the control circuit 70 is switched from the stationary mode to the operation mode. Further, the mode control unit 900 notifies the power supply control unit 902 of the operation mode signal. When the operation mode signal is notified to the power supply controller 902, a control signal is output from the output 804 and the power supply circuit 68 is activated. When the power supply circuit 68 is activated, DC power is supplied from the output 806 to each circuit of the communication block 86.

When the control circuit 70 enters the operation mode, in step 1002, the switch detector 904 detects the input information indicating the ON state of the switch 18M output from the output 808M of the operation block 74. The switch detector 904
When it is determined that the detected input information is information that the switch 18M is turned on, the registration mode is set, and the data processing unit 908 is notified of the registration mode setting signal. In addition, when the switch detection unit 904 detects input information, the confirmation unit 906
Notify the input signal to. Confirmation section when input signal is notified
302 outputs at its output 816 a start-up signal that drives the oscillator 38. When a start signal is input to the oscillator circuit 38, a low frequency signal is generated, and this low frequency signal is input to the input 822 of the reception amplifier 62 via the resistor R connected to the output 818 thereof. This low frequency signal is amplified by the reception amplifier 62 and causes the handset 16 connected to its output 824 to sound a switch detection sound. Hereinafter, this operation of generating a switch detection sound from the handset 16 by turning on the switches 10 and 18 will not be particularly described. Further, the operation of steps 1004 to 1016 shown below may be the same as the operation of steps 402 to 414 of the embodiment shown in FIG. This operation will be briefly described. In step 1004, the switch detection unit 904
The ON states of the switches 10P, 10S and 10E are detected by the switch, and an input signal indicating the input state is input to the data processing unit 908.
Will be notified. When this ON state is detected, step 10
A switch detection sound is emitted at 05, and the routine proceeds to step 1006, where it is determined whether 2 seconds have elapsed since the input information was detected. At this time, if there is next input information within 2 seconds after the input information is detected, the process returns to step 1004 and the input information is detected. In this way, the input information corresponding to one digit of the numerical data is detected.

If the next input information is not detected even after 2 seconds have elapsed since the input information was detected, the process proceeds to step 1008, and the switch detection unit 904 determines that the one-digit input has been completed. To its output 816. The activation signal finally causes the handset 16 to output a confirmation sound. Next, proceeding to step 1010, the data processing unit 908 converts these input signals notified from the switch detection unit 904 into numerical data, and recognizes a one-digit number. Next, in step 1012, when the input information indicating that the switch 18M is turned on is detected, the process proceeds to step 1012. In this case, if the input information due to the ON state of one of the switches 10P, 10S and 10E is detected,
Returning to step 1004, the switch detection unit 904 detects this input information. In the same manner, the processing from step 1004 to step 1012 is repeated until the switch detector
Numerical data corresponding to the input signal notified from 904 is generated.

On the other hand, when the switch detection unit 904 detects the input information in which the switch 18M is turned on in step 1012 and the input signal is notified to the data processing unit 908, the process proceeds to step 1014 and the data processing unit 908 is notified. Thus, the storage area of the memory circuit 72 corresponding to this input signal is designated. next,
In step 1016, the numerical data generated by the data processing unit 908 up to that point is written in the storage area of the memory circuit 72, and the registration mode ends.

When the registration mode ends, the process proceeds to step 1018, and the data processing unit 908 notifies the switch detection unit 904 of the registration mode end signal. When the switch detection unit 904 is notified of the end signal, the switch detection unit 904 notifies the mode control unit 900 of this end signal. Upon receiving the notification of the end signal, the mode control unit 900 notifies the power supply control unit 902 to shift to the stationary mode. Power control unit 902
When this notification is received, the control signal output from the output 804 is cut off to stop the output of the power supply circuit 68.
As a result, the power supply to the communication block 86 is cut off. Further, the mode control unit 900 outputs a reset signal (not shown) to the flip-flop circuits 78P, 78S, 78E and 78M of the operation circuit 74. After that, the mode control unit 900 shifts each functional unit of the control circuit 70 to the stationary mode.

Numerical data representing the telephone number registered in the memory circuit 36 as described above is read at the time of calling and transmitted as a selection signal. Similar to the operation described in the registration mode as shown in FIG. 11, in step 1100, the switch output from the output 808M of the operation block 74.
The input information indicating the ON state of 18M is the input 81 of the control circuit 70.
By inputting 0, the control circuit 70 is shifted from the stationary mode to the operation mode. The operation mode is entered, and the routine proceeds to step 1102, where the input information indicating the ON state in which the switch 10P is turned on is input to the input 808M of the control circuit 70 and detected by the switch detection unit 904. When this input information is detected, the data processing unit 908 is notified of an input signal representing this input information. Next, proceeding to step 1104, the numerical data corresponding to this input signal is sequentially read from the memory circuit 36 by the data processing unit 908. Then in Step 1106
At this time, the call instruction signal is sent from the switch detection unit 904 to the call unit 91.
0 is notified and the numerical data is transferred to the communication unit 912. When the numerical data is transferred to the communication unit 912, the communication unit 91
At 2, the control signal for capturing an empty line necessary for calling and the control signal for setting the communication channel are output from the output 814 to control the transmission / reception circuit 86 of the communication block 76. When the call channel is set, the communication unit 912 converts this numerical data into a call selection signal and outputs it from its output 814.

The communication block 76 modulates the signal including the calling selection signal and transmits it from the antenna 12. When the channel with the base station is opened, proceed to step 1008,
The communication unit 908 controls the transmission / reception circuit 86 to make an actual call. Next, at step 1110, the switch detector 904 detects the input information generated by turning on the switches 10P, 10S, 10E and 18M during this call, and the communication unit 908 is notified of the input signal, or the communication unit 908 receives the input signal. When the call end state of the other party is detected from the communication block 76 at, the process proceeds to step 1112. In step 1112, the communication section 908 outputs a control signal to the communication section 908 to terminate the communication and terminate the communication to terminate the communication. Step when communication ends
In step 1114, the communication unit 908 notifies the switch detection unit 904 of the end signal. After that, just like at the end of registration mode,
This end signal is notified to the mode control unit 900, and the mode control unit 900 notifies the power supply control unit 902 to shift to the stationary mode. Upon receiving this notification, the power supply control unit 902 disconnects the activation signal output to its output 804. The start signal input to the input 804 of the power supply circuit 68 is cut off, and the power supplied from the output 806 to the communication block 76 is cut off. In addition, the mode control unit 900
Outputs a reset signal (not shown) to the flip-flop circuits 78P, 78S, 78E and 78M of the operation circuit 74, and thereafter shifts each functional unit of the control circuit 70 to the stationary mode.

As described above, the portable telephone terminal devices 1 and 4 are operated by pressing any one of the push buttons (P), (S) and (E) 10 to reach a desired destination. You can make a call. In this case, there are very few push buttons for selecting the destination whose telephone number has already been registered, and the desired destination is registered from among the three push buttons 10 for making a call. Since it suffices to push the push button, it is possible to make a call to a desired destination without fail. Therefore, especially in an emergency, there is no complicated operation, so that a call can be made quickly. In addition, since the pressing surface of the push button (P) 10 is set larger than the other push buttons (S) and (E), it can be easily distinguished from the other push buttons 10 even in the dark. Therefore, it can be operated easily and quickly. As described above, in the mobile phone device according to the present invention, the telephone numbers are stored in correspondence with the push buttons (P), (S), (E) 10, respectively, and the push buttons (P), (S), ( E) Since each of 10 has functions for making a call, receiving a call, and ending a call, in the extreme, one push button can be used to perform the minimum necessary telephone operations. Therefore, it is possible to provide a very convenient mobile phone device, which can be easily handled by small children and the elderly. Further, since the mobile phone terminal devices 1 and 4 are not provided with the number buttons corresponding to the numbers 0 to 9 in a one-to-one manner, the call destination can be limited. In particular, when the memory button (M) 18 is configured so as not to be easily pressed, no call can be made to other than the registered call destination, which is advantageous when lending to a person.
