  • Portable computer comprising keyboard and coordinate input tablet hingedly connected to a main body case through a junction base having a cylindrical element defining a linear groove therethrough
    Patent number: 5594619
    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.

  • Computer having integral type hand writing input/display device and keyboard
    Patent number: 5202844
    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.
