A main body case encasing a keyboard and an upper case encasing an integrated display/input device are coupled by first and second hinge units and a junction base (with a cylindrical element defining a linear groove there through) to be arbitrarily pivotal from a state wherein the keyboard faces the integrated display/input device to a state wherein the back surface of the integrated display/input device faces the keyboard. Depending on the position of the integrated display/input device, a mode designation means designates one of first and second modes, the first mode being a mode in which the integrated display/input device performs an operation in an ordinary manner, the second mode being a mode in which the integrated display/input device performs an operation in a manner reversed 180.degree. with reference to the coordinate system in the first mode.

Portable computer comprising keyboard and coordinate input tablet

A main body case for storing a keyboard and an upper case for storing an integrated display/input device are coupled by first and second hinge units, disposed through a groove in the main body case, to be arbitrarily pivotal from a state wherein the keyboard faces the integrated display/input device to a state wherein the back surfaces of the keyboard and the integrated display/input device face each other.

Portable computer having keyboard and coordinate input tablet hingedly

A main body case for storing a keyboard and an upper case for storing an integrated display/input device are coupled by two hinge units arranged perpendicularly to one another to be arbitrarily pivotal from a state wherein the keyboard faces the integrated display/input device to a state wherein the back surfaces of the keyboard and the integrated display/input device face each other.

Portable computer with keyboard and having display with coordinate input

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.
