る座標読取装置のアース構造。 The base includes a sense line substrate having a plurality of conductive wires arranged in parallel, a base that keeps the sense line substrate flat, a surface plate that protects the sense line substrate, and a protective film made of synthetic resin on the entire surface. In a coordinate reading device, a metal back plate installed on the side opposite to the side on which the sense line board is installed is fixed by a frame having a U-shaped cross section, and the metal back plate is fixed on the frame side and on the plane of the back plate. A screw hole is provided in the surface that comes into contact with the surface, and the screw fitted into the screw hole penetrates the synthetic resin and contacts the metal backing plate,
A grounding structure for a coordinate reading device, characterized in that the frame and the back plate are electrically connected.
