Abstract
An information processing apparatus includes a hinge mechanism for rotating an integral type hand writing input/display device and a keyboard from a position, in which the display surface of the integral type hand writing input/display device and the surface of the keyboard face each other, to a position of a desired opening angle. The input/display device 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 can retain the desired opening angle. There are further provided an attitude sensor for detecting which of the integral type hand write input/display device and the keyboard is situated substantially horizontally, and a changing circuit 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.
