Abstract
Abstract An information processing apparatus includes a hinge mechanism (16) for rotating an integral type hand write input/display device (14) and a keyboard (18) from a position, in which the display surface of the integral type hand write input/display device and the surface of the keyboard face each other, to a position of a desired opening angle. The input/display device (14) is provided on a top portion of a processing apparatus body, is constituted by integrally superposing a tablet device for coordinate input on a display surface of a display device, and inputs coordinate data representing a location indicated voluntarily on the tablet device. The hinge mechanism (16) can retain the desired opening angle. There are further provided an attitude sensor (12) for detecting which of the integral type hand write input/display device and the keyboard is situated substantially horizontally, and a changing circuit (Figs. 10 and 11) for changing the display contents of the integral type hand write input/display device and coordinate data detection location, in accordance with the ON/OFF state of the attitude sensor.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
154 words
An information processing apparatus comprising a processing apparatus body (10); an integral type hand write input/display device (14), constituted by integrally superposing a tablet device for coordinate input and a display device, for inputting coordinate data representing a location indicated voluntarily on the tablet device; a keyboard (18), and a rotary support mechanism (16) for rotating said integral type hand write input/display device and said keyboard from a position, in which the display surface of the integral type hand write input/display device and the surface of the keyboard face each other, to a position of a desired opening angle, characterized in that there are provided: detecting means (12) for detecting a specific state of said information processing apparatus; and changing means (Figs. 10 and 12) for changing the display contents of the integral type hand write input/display device and coordinate data detection location, in accordance with the detection result of the attitude detecting means.
Claim 2
Dependent Claim
40 words
