2. Description of the Related Art With the spread of portable telephones, not only small size and light weight but also ease of use that meets the needs of customers is required. The mobile wireless phone is provided with a display unit for providing various information such as date, time, battery level, radio wave condition, and a key button unit for operating not only calling / incoming but also other functions. .

[0003] A conventional portable telephone has the illuminated display section and key button section so that the display section can be checked and the key button section can be operated at night.
However, as means for turning them on, it is necessary to perform an operation by pressing a key button to turn them on. As the size of the telephone body has been reduced, the size of the key buttons has also been reduced, and the operability is not good. The operation of pressing a small keypad in the dark is cumbersome, and an unintended operation of a key button may cause an unintended function to operate. Further, in the conventional portable wireless telephone, the display section and the key button section are turned on by the key button operation not only at night but also in a bright surrounding area, so that power is consumed more than necessary and battery consumption is accelerated.

On the other hand, the off-hook / on-hook operation when an incoming call is received includes a method by pressing a key button as described above, and an operation by opening and closing a flap in a telephone with a flap. Regarding the operation of pressing the key button,
As described above, there is a possibility that a communication channel may be disabled by a wrong key button operation or a malfunction may occur. The operation of opening and closing the flap does not cause the malfunction as described above, but is an operation in which opening and closing the flap itself is troublesome.

[0005] In consideration of usability, it is necessary to realize the lighting of the illuminated display unit and the key button unit and the off-hook / on-hook operation at the time of an incoming call by a simple operation. Also,
With the demand for smaller and lighter batteries, battery capacity tends to decrease, and low power consumption must be achieved.

[0006]

SUMMARY OF THE INVENTION In order to overcome the above-mentioned problems, it is an object of the present invention to provide a portable telephone capable of illuminating an illuminated display unit and a key button unit and enabling off-hook / on-hook with a simple operation of tilting a telephone body. And a method of reducing power consumption during illumination.

[0007]

To achieve the above object, the present invention comprises a portable radiotelephone having a tilt detecting means for detecting tilt and a light detecting means for detecting light, Of the surfaces constituting the housing, the surface having the illuminated display unit and the key button unit is at a first position inclined at an arbitrary angle with respect to the ground, with the top surface of the housing up,
It is detected by the inclination detecting means whether or not it is at the second position other than that, and the illumination state of the display unit and the key button unit is provided. By using the inclination detecting means, the surface having the illuminated display portion and the key button portion among the surfaces constituting the housing is inclined from about 40 degrees to about 90 degrees with respect to the ground, with the upper surface of the housing facing up. The inclination can be detected by setting the position as the first position and setting the other positions as the second positions.

By having the light detecting means for detecting the amount of light in the surroundings, the illuminating state of the display unit can be adjusted based on the light amount detection information and the inclination detection information, thereby realizing low power consumption. When there is an incoming call and a call is being made, an off-hook state and an on-hook state are brought about according to the state from the detection means. In tilt detection,
When detecting the first state continuously for a certain period of time,
Since an illuminated state or an on-hook / off-hook state is brought about, malfunction due to vibration or the like can be prevented.
