DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below. Embodiment 1 FIG. FIG. 1 is a block diagram showing a portable telephone according to a first embodiment of the present invention. In the drawing, reference numeral 1 denotes a brightness when the portable telephone is in a bag and when the bag is opened and when the portable telephone is closed. The light sensor (light detection unit) 2 for detecting the position of the portable telephone is an operation unit for notifying the location of the portable telephone.
This uses a backlight LED (light emitting diode) of D (liquid crystal display). A control unit 3 has a call control function of the mobile phone, and operates the operation unit 2 when the brightness detected by the optical sensor 1 becomes dark and then becomes bright again. And outputs to the control unit 3 a signal for enabling or disabling the location notification function in the bag according to the operation of the user, and outputs a signal for stopping the operation of the operation unit 2 to the control unit 3. This is the operation unit that outputs to

Next, the operation will be described. FIG. 2 is a flowchart showing the operation of the mobile phone according to the first embodiment of the present invention.
Is pressed (step ST1), the backlight LED of the LCD, which is the operation unit 2, is turned on under the control of the control unit 3 (step ST2). After 10 seconds (step ST3), the power consumption is reduced. The light is turned off to suppress it (step ST4). At this time, the surrounding brightness is detected by the optical sensor 1 (step ST5). If the mobile phone is not yet stored in the bag, or if the bag is not closed even if it is stored in the bag, the optical sensor 1 continues to detect that the surroundings are bright,
The process in the control section 3 loops step ST5. Thereafter, when the bag is closed, the optical sensor 1 detects that the surroundings are dark (step ST6), and the processing in the control unit 3 loops step ST6. If the user wants to use the portable telephone again, he or she will open the bag. At this time, the optical sensor 1 detects that the surroundings have become bright due to the opening of the bag, and At 3, the backlight LED of the LCD, which is the operation unit 2, is turned on by the light sensor 1 detecting that the surroundings have become brighter (step ST7). As described above, when the user wants to use the portable telephone set in the bag, the user is notified by turning on the backlight LED of the LCD even in a dimly-lit bag, so that the location of the portable telephone can be determined. Easy to confirm. If the user wants to turn off the backlight LED of the LCD after taking out the mobile phone from the bag, the user operates the operation unit 4 and sends a signal to the control unit 3 to stop the operation. Is output, and the control unit 3 outputs LC
The operation unit 2 is controlled so as to turn off the backlight LED of D.

If the user does not want to use the location notification function of the portable telephone, for example, if the portable telephone is not in a bag but in a pocket or the like, the user can find the location of the portable telephone. Since the location notification function is known, it is not necessary to use the location notification function. In this case, the operation of the location notification function is disabled by the operation unit 4 and the operation unit 4 instructs the control unit 3 to disable the location notification function. A signal is output, and the control section 3 performs steps ST5 to ST5 in FIG.
7 can be invalidated. Further, when the user wants to use the location notification function of the mobile phone, the operation unit 4 performs an operation of enabling the location notification function, and the control unit 3 enables the processing of steps ST5 to ST7 in FIG. can do.

As described above, according to the first embodiment, the backlight LED of the LCD is turned on when the surrounding brightness detected by the optical sensor 1 becomes dark and then becomes bright again. Therefore, if you want to use the mobile phone in your bag, you will be notified by the backlight LED on the LCD even in a dimly lit bag, so check the location of the mobile phone. Can be made easier. In addition, by operating the operation unit 4, the location notification function of the portable telephone can be set to be enabled or disabled, and the backlight LED of the LCD can be turned off after confirming the location of the portable telephone. In the first embodiment, it has been described that the location notification function of the mobile phone is effective when the mobile phone is placed in a bag. However, when the mobile phone is stored in a dark place other than the bag. It is effective to use as appropriate.
