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 23 A 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.

What is claimed is: 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
What is claimed is: 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. 2. 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; and a second display which is exposed regardless of whether the second case is opened or closed; wherein the first display and the second display are constituted by a unitary display device which can display on both a front side and a back side, and wherein the first display is automatically illuminated only when the second case is in the fully open position, and wherein the second display is automatically illuminated only when the second case is in the fully closed position. 3. A portable communication apparatus according to claim 2, wherein the display device is provided in either the first case or the second case, and the first case or the second case in which the display device is provided has a window for the first display in the inner face and has a window for the second display in the outer face. 4. A portable radio communication apparatus according to claim 3, wherein the display device has a first reflective plate on the opposite side to the window for the first display and has a second reflective plate on the opposite side to the window for the second display. 5. 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 open position, opened; a second display which is exposed regardless of whether the second case is opened or closed; an open/closed position detector which detects whether the second case is in the fully open position or fully closed position; a display controller for directing a display driving supply, which controls the first display and the second display to be turned on and off, with reference to what the open/closed position detector has detected, and a controller which controls the display controller for directing the display driving supply so that the first display is automatically illuminated and the second display is automatically turned off only when the second case is in the fully open position, and the second display is automatically illuminated only when the second case is in the fully closed position. 6. A portable radio communication apparatus according to claim 5, wherein the second display is disposed on the opposite side to the first display, and either the first case or the second case has a window for the first display in the inner face and has a window for the second display in the outer face. 7. A portable radio communication apparatus according to claim 5, wherein the controller which controls the display controller for directing the display driving supply to turn off the first display if the open/closed position detector has detected the second case being in the closed position.
