Abstract

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.
