INFORMATION PROCESSOR

PURPOSE: To improve the rigidity of a display part while holding the device small-sized and thin on the whole by forming the outer periphery of a display part case in a nonflat shape which slants gently to the front, and making the shape of a main body case conform with it. CONSTITUTION: The display part consists of a display device 6 which has an information display function and a display case 1 which covers the display device 6 so that only its screen part is exposed, and the display part case 1 is provided with a curved surface which is gently protruded from the outer periphery of the screen to the outer periphery of the case. Further, a main body part consists of an input device 7, a controller, and a main body case 2 which covers the input device 7 so that only its input part is exposed, and the main body case 2 is provided with a curved surface which is gently recessed to the outer periphery in conformity with the curved surface of the display part case 1. Then when the display part is closed, the projection curved surface on the side of the display part case is put in the recessed curved surface on the side of the main body case 2. Consequently, the height of the flank of the display part case is increased and the rigidity is increased by rib effect.
