Claims

[Scope of utility model registration request]

A thin metal wire method in which a plurality of thin metal wires are arranged in parallel on one side of an elastic insulating plate, and a resistor with a current passed through one end of the thin wire is pressure-welded perpendicular to the thin wires. A resistive film-type abscissa doublet and a ordinate doublet, each provided with a resistive film carrying a current, are placed one on top of the other with an insulating spacer interposed so that their surfaces face each other and the directions of the current are perpendicular to each other. In a graphic input device that presses one point and detects a voltage that indicates the coordinates of the pressed point, before detecting the voltage that indicates the coordinates, a circuit is provided to destroy the oxide film of the thin metal wire or resistive film at the pressed point using current. A graphic input device characterized by:
