Portable radio communication apparatus
First Claim
1. A portable radio communication apparatus which has a sound input device for inputting sound, a sound output device for outputting sound, an input device for inputting various signals, and a communication device for communicating various communication data including audio data, text data, and image data, the portable radio communication apparatus comprising:
- a first case;
a second case which is connected to the first case so as to rotate between a fully open position, in which the second display is in an unused condition, and a fully closed position, in which the second display is in a used condition, with respect to the first case;
a first display which is exposed when the second case is in the fully open position;
a second display which is exposed regardless of whether the second case is opened or closed;
a first illuminator which illuminates the first display;
a second illuminator which illuminates the second display;
an electric power supply switch which can switch between lines to supply electric power for illumination to the first illuminator and the second illuminator;
an open/closed position detector which detects whether the second case is in the fully open position or the fully closed position; and
a controller which controls the electric power supply switch, with reference to what the open/closed position detector has detected, to automatically supply electric power to the first illuminator only when the second case is in the fully open position, so that the first display is automatically illuminated only when the second case is in the fully open position, and to automatically not supply power to the second illuminator when the second case is in the fully open position so that the second display is automatically not illuminated, and to automatically supply electric power to the second illuminator only when the second case is in the fully closed position, so that the second display is automatically illuminated only when the second case is in the fully closed position.

Abstract
An object is to provide a portable radio communication apparatus which allows a user to easily view displayed contents when the apparatus is folded even in the nighttime or in a dark place, and which can extend the battery life. A second case 4 is connected to a first case 2 so as to be in open and closed positions with respect to the first case 2. A main display section 11 which is exposed when the second case 4 is in the open position, a sub-display section 12 which is exposed whether the second case 4 is in the open or closed position, a main illuminating device 23A which illuminates the main display section 11, and a sub-illuminating device 23B which illuminates the sub-display section 12 are provided. A driver 24 which selects a line to supply electric power for illumination to the main illuminating device 23A or the sub-illuminating device 23B, and a detecting switch 22 which detects whether the second case 4 is in the open or closed position, are also provided. A control section 25 is also provided which controls the driver 24, with reference to the detected result, to supply electric power to the main illuminating device 23A when the second case 4 is in the open position, and to supply electric power to the sub-illuminating device 23B when the second case 4 is in the closed position.
