て容易に通信が行える時代を迎えている。2. Description of the Related Art In recent years, mobile phones have been remarkably popularized, and many people have used them. Also, a so-called pager that enables a call function and simple character data reception has been actively used, and the era of easy communication using various communication media has entered.
【０００３】携帯電話は双方向の通信が行えることか
ら、迅速に大量の情報のやりとりが可能である反面、通
話時だけでなく受信待受け時においても消費電力が大き
く長時間の使用には不向きであり、且つ、通信可能なサ
ービスエリアが狭いと云った欠点がある。Since a mobile phone can perform two-way communication, it is possible to exchange a large amount of information quickly, but on the other hand, it consumes a large amount of power not only during a call but also during reception standby, and is not suitable for long-time use. There is a drawback that the service area where communication is possible is small.

も広いと云った特徴がある。[0004] On the other hand, the pager has a drawback that it only transmits information unilaterally and the amount of information that can be transmitted is small. However, the pager can be formed in a small size, has low power consumption, and is used for a long time. And the service area is wide.
【０００５】そのため、従来より、携帯電話とページャ

便利である。[0005] For this reason, conventionally, it has been proposed to house both a mobile phone and a pager in the same housing. In this case, the contact information can be received by the pager even outside the service area of the mobile phone, which is extremely convenient.

で、電源管理が面倒となるという欠点がある。However, when the mobile phone and the pager are housed in the same housing, the structure of the power supply becomes a problem. In other words, if the power supply is shared by the mobile phone unit and the pager unit, it cannot be used for a long time. On the other hand, if the power supply is separated, charging or battery replacement is required. Has to be performed separately, and thus there is a disadvantage that power management becomes troublesome.

The mobile phone device and the pager device are combined, and both are operated with the same power supply. While the battery has sufficient power, the mobile phone device and the pager device are kept operable, and the battery is running out of power. Sometimes, the power supply to the mobile phone device is cut off, the power supply to the pager device operable with low power consumption is continued, the communication is always ensured, and the rational use of the battery is attempted. An object of the present invention is to provide a mobile phone device with a pager function that can reduce the complexity of management.

る。FIG. 3 is an explanatory diagram showing the discharge characteristics of the lithium secondary battery. In the figure, a curve H indicates discharge characteristics when the telephone circuit section 8 is in a transmission / reception state (during a call) and the pager circuit section 7 is operating. As is evident from this curve, a continuous call requires only 5
About time, the battery voltage drops from the initial 4.2V to 2.7V (point D on the curve H) near the discharge end voltage. on the other hand,
When the power supply to the telephone circuit section 8 is turned off, the curve P
As shown by, the drop of the battery voltage becomes considerably slow. Accordingly, the battery voltage is detected by the voltage detection circuit 2 irrespective of whether the user is talking or waiting, and when the battery voltage reaches 3.2 V (point A of the curve H), the first detection is performed. A signal is output to the control unit 3. When receiving the first detection signal, the control unit 3 displays on the display unit 15 the fact that the remaining talk time is short, and notifies the user. Since the display 15 is not visible to the user during a call, the control unit 3 sends the amplifier 5 in addition to the display on the display 15.

(Point : first voltage ), when the voltage detection circuit 2 detects that the voltage has reached the first voltage and outputs the second detection signal, the control unit 3 informs the telephone circuit unit 8 that reception is impossible. Display 15
And the switching transistor 10
The positive voltage output to the telephone circuit unit 8 is changed to zero, the switching transistor 10 is turned off, and the power supply to the telephone circuit unit 8 is cut off. When the battery voltage reaches 3 V during a call, the controller 3 outputs an intermittent signal to the amplifier 5 in a different form from the previous one,
1 and 11 are blinked to indicate that the remaining time during which the call can be made is almost exhausted. After the call is completed, the power supply to the telephone circuit section 8 is cut off, and the above-described display is performed. By cutting off the power supply to the telephone circuit section 8, the power consumption accompanying the receiving operation in the telephone circuit section 8 is eliminated. Accordingly, the main power consumption of the portable telephone device with a pager function of this embodiment is only due to the reception operation in the pager circuit section 7, and the voltage drop of the lithium secondary battery becomes gentle as shown by the curve P. As a result, the third
The means of communication from the third party is limited to the pager, but can be contacted by a third party on a few days. Also, in this state, a telephone call can be made. That is, in this embodiment, when the transmission key (instruction means) in the keypad 22 is operated in this state, the control unit 3 returns the output to the switching transistor 10 from zero to a positive voltage, and the switching transistor 10 is turned on. When the power supply to the telephone circuit unit 8 is resumed and the call is terminated and the end key in the keypad 22 is operated, the control unit 3 changes the output voltage to the switching transistor 10 from the positive voltage to zero again. And the power supply to the telephone circuit unit 8 is cut off by turning off the switching transistor 10. During this transmittable period, the battery voltage further decreases and becomes 2.8 V
(Point C on curve H and point C 'on curve P).
That is, when the battery voltage drops to 2.8 V and the battery voltage detection circuit 2 detects it and outputs a third detection signal to the control unit 3, the control unit 3 thereafter transmits a signal from the key input unit 4. Even if a signal indicating that the key is operated is input, the output to the switching transistor 10 is maintained at zero, and the power supply to the telephone circuit unit 8 is not restarted. That is, after the battery voltage drops to 2.8 V or less, only the pager circuit unit 7 is completely operated.

The control unit 3 displays on the display unit 15 that the reception by the pager circuit unit 7 is also disabled, and changes the positive voltage output to the switching transistor 9 to zero.
The switching transistor 9 is also turned off to cut off the power supply to the pager circuit unit 7. Then, a notification signal is output to the amplifier 6, and a sound is emitted from the speaker 12 to urge the user to charge the battery.
