  • Patent number: 5451724
    Abstract: A touch panel to detect a coordinate of an arbitrary position where pressure is applied. The touch panel includes a substrate, a resistor layer provided on the substrate, a spacer layer made of an insulator material, a conductor layer confronting the resistor layer via the spacer layer, a plurality of point electrodes provided on the resistor layer at a peripheral part of the resistor layer along each side of the resistor layer, and a plurality of switching elements provided above the substrate and electrically coupled to the point electrodes for supplying a voltage to the point electrodes. The spacer layer is made up of a plurality of spacer pieces which are arranged so that an electrical contact is made between the conductor layer and the resistor layer when a pressure is applied at an arbitrary position on the conductor layer.

  • Patent number: 4641980
    Abstract: A printer including a casing having a front face, a printing unit, and a control circuit. The printing unit includes a printing medium attaching portion and a printing head portion pivotably attached to the printing medium attaching portion. The printing unit is supported in the casing by a moving mechanism so that the printing unit can be freely drawn out forward from the front face of the casing. The moving mechanism also automatically positions the printing head in an open position with respect to the printing medium attaching portion when the printing unit is drawn out from the casing.
