Abstract

PROBLEM TO BE SOLVED: To save the power consumption of a battery and to prolong a communication period by stopping power supply from an internal battery to an LCD and an LED packaged in a portable telephone set when the main body of the portable telephone set is held in a hand and a receiver is brought into contact with the ear of a carrying person in a communication state. SOLUTION: When a CPU 15 receives an incoming call through a TX1, communication is started and the carrying person holds this portable telephone set in the hand and brings a transmitter 2 to his/her own ear, by the sensing detection of touch sensors 11-1 and 11-2, a sensor reception part 10 sends out detection signals to the CPU 15. Then, the CPU 15 controls a switch part 12 and stops voltage supply from the battery 13 to the LEDs 9-1 and 9-2 and the LCD 7. Then, when the CPU 15 detects communication end from the TX1 and an RX3, the CPU 15 controls the switch part 12 again, supplies a voltage from the battery 13 to the LCD 7 and the LEDs 9-1 and 9-2 and lights the LCD 7 and the LEDs 9-1 and 9-2.

And parts, and a CPU for controlling the entire cellular phone.

[0009]

Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing a portable telephone according to an embodiment of the present invention, and FIG. 2 is a flowchart showing an operation of turning off the light during a call according to the present embodiment.

In FIG. 1, a mobile phone according to the present embodiment has a transmitting section (TX) 1 for transmitting a dial signal and a transmission signal from a transmitter 2 via an antenna 16, and a reception section via the antenna 16. A receiving unit (RX) 3 for transmitting the received reception signal to the receiver 4 and an LCD 7 for displaying a dial number at the time of calling.
, An LED 9-1 indicating that power is turned on by the battery 13, an LED 9-2 indicating that a call is in progress, and an LED driving unit 10 driving the LEDs 9-1 and 9-2. A touch sensor 11 for detecting that this mobile phone is held by a hand of a carrier for a call.
-1, a touch sensor 11-2 for detecting that the ear of the carrier is in contact with the receiver 4 for a call, and a battery 13
A battery sensor 11-3 for detecting the voltage of the battery, a sensor receiving section 10 for transmitting touch signals and detection signals from the touch sensors 11-1 and 11-2 and the battery sensor 11-3 as sensor reception, and a dial number. An operation key unit 5 to be input, a memory unit 14 storing its own number, a control program, and the like, and a voltage from the battery 13
7, a switch unit 12 for switching the supply to the LEDs 9-1 and 9-2, and a CPU 1 for controlling the entire mobile phone.
5 is provided.

Next, the operation of the present embodiment for turning off the light during a call will be described with reference to FIG. 2 and FIG.

The LED 9-1 in the present embodiment illuminates the operation key unit 5 when the power from the battery 13 is turned on.

In FIG. 2, from the standby state (S1) of the mobile phone of the present embodiment, the CPU 15 receives an incoming call via the TX1 and is in a call (S2), and the carrier holds the mobile phone in his hand. When the transmitter 7 is put on the user's ear (S3), the sensor receiver 10 sends a detection signal to the CPU 15 in response to detection by the touch sensors 11-1 and 11-2. Therefore, the CPU 15 controls the switch unit 12 to stop the voltage supply from the battery 13 to the LEDs 9-1 and 9-2 and the LCD 7 (S4).

The CPU terminates the call from TX1 and RX3.
15 (S5), the CPU 15 controls the switch section 12 again to supply the voltage from the battery 13 to the LCD 7, the LEDs 9-1 and 9-2, and the LCD 7, the LED 9-1 and the LED 9-1.
9-2 is turned on (S6).

As described above, in the portable telephone of the present embodiment, since the portable person does not look at the LCD 7 and the operation key unit 5 during a call, the LCD 7, the LEDs 9-1 and 9-2 are turned off, and the power consumption of the battery is reduced. Is wearing.

[0017]

As described above, the present invention is mounted on a portable telephone when a portable person holds the main body of the portable telephone by hand and the handset of the portable telephone comes into contact with the ear of the portable telephone in a talking state. Since the LCD and the plurality of LEDs are turned off during a call by providing a power supply stopping means for stopping the supply of power from the internal battery to the LCD and the plurality of LEDs, the power consumption of the battery is saved to shorten the call period. There is an effect that can be lengthened.
