In FIG. 1, 1 is an antenna, 2 is a transmitting / receiving section for transmitting / receiving a radio signal to / from a base station (not shown) via the antenna 1, and 3 outputs a voice signal received and demodulated by the transmitting / receiving section 2. The speaker 4 is a microphone that converts an input voice into a voice signal and supplies the voice signal to the transmission / reception unit 2.

Reference numeral 5 denotes an operation unit for inputting telephone numbers and character data, etc., 6 denotes a display unit for displaying image signals received and demodulated by the transmission / reception unit 2 and telephone numbers and character data input by the operation unit 5; Denotes an illumination unit for illuminating the operation unit 5 and the display unit 6, and 8 stores telephone directory data, state data indicating the use state of the apparatus, and illumination data indicating the relationship between the use state of the apparatus and turning on / off the illumination. Storage unit 9 is storage unit 8
Is a control unit that controls on / off of the illumination unit 7 based on the state data and the illumination data stored in the storage unit, and controls the operation of other units.

In the portable telephone configured as described above, for example, in a state where the illumination data as shown in FIG. 2 is stored, the control unit 9 sets the state of the apparatus main body in a standby state or in a voice communication state. In some cases, the illuminating unit 7 is turned off, and when the apparatus body is in a state of performing data communication or checking the content of the received data and further performing a user operation (inputting information), the illuminating unit 7 is turned on. When the main body is in a state of a user operation (other than information input), the illumination unit 7 is turned on for a certain period after the input.

Therefore, according to the above-described operation control, unnecessary power consumption is suppressed by turning off the light during standby or during voice communication, and during data communication, during confirmation of received data content, or during input of user data.

The control unit 9 operates based on the ambient light intensity measured by the light receiving unit 11, the state data stored in the storage unit 8, and the illumination data. The lighting unit 7 is configured to perform on / off control.

In the portable telephone constructed as described above, for example, in a state where the illumination data as shown in FIG. The lighting unit 7 is turned off regardless of
When the device body is in a standby or voice communication state in a dark state, the lighting unit 7 is turned off, and in a dark state, the device body is performing data communication or checking the content of received data. When the apparatus is in the middle (information input) state, the illumination unit 7 is turned on. When the apparatus body is in the state of being operated by the user (other than information input) in a dark state, the illumination unit 7 is maintained for a certain period after the input. 7 is turned on.

Therefore, according to the above-described operation control, when the surroundings are bright, during standby or during voice communication, the lighting is turned off, thereby suppressing wasteful power consumption, while performing data communication, checking received data contents, and the like. By turning on the lighting during user data input, usability can be improved.

In FIG. 5, reference numeral 21 denotes a light amount adjusting unit for adjusting the light amount of the illumination unit 7, which is controlled based on the ambient light intensity measured by the light receiving unit 11, the state data stored in the storage unit 8, and the illumination data. The unit 9 is configured to control the light amount adjustment unit 21 to adjust the light amount of the illumination unit 7.

For example, in the state where the portable telephone constructed as described above stores illumination data as shown in FIG. 2, the control unit 9 operates when the apparatus main body is in a standby or voice communication state. In the case where the light amount is reduced by the light amount adjusting unit 21 and the illuminating unit 7 is turned off, and the apparatus main body is in a state of performing data communication or checking the content of received data and further performing a user operation (information input), the light amount adjusting unit When the light amount is increased by 21 and the illuminating unit 7 is turned on, and the apparatus body is in a state of a user operation (other than information input), the light amount is increased by the light amount adjusting unit 21 for a certain period after the input to turn on the illuminating unit 7. When the illuminating unit 7 is turned on, the light amount adjusting unit 21 is controlled to reduce the amount of light from the illuminating unit 7 as the ambient luminous intensity measured by the light receiving unit 11 increases.

Therefore, according to the above-described operation control, the amount of illumination is reduced when the surroundings are bright, and the illumination is turned off during standby or voice communication, thereby suppressing unnecessary power consumption and reducing data communication during data communication. The convenience can be improved by turning on the illumination while confirming the contents of received data or inputting user data.

[0028]

As described above, according to the present invention, the use state of the data communication function is detected as the use state of the apparatus main body, and based on the detected use state, the illumination of the display unit or the operation unit is turned on.
