Abstract:
1. A manufacturing apparatus of a coordinate detecting device, comprising: a plurality of probes each provided at a position which comes into contact with a surface of a resistive film that is transparent in a visible region and formed on one surface of a transparent glass substrate of the coordinate detecting device to measure electric potentials of the surface of the resistive film to which a voltage is applied via a common electrode of the coordinate detecting device, wherein said surface of the resistive film faces away from the transparent glass substrate; a laser light source provided at a position facing the other surface of the transparent glass substrate opposite to said one surface, which irradiates laser light toward the resistive film through the transparent glass substrate to remove a part of the resistive film and form a resistive film removed part based on the electric potentials measured with the plurality of probes; an optical system which converges the laser light; an X-Y table which moves the substrate of the coordinate detecting device at least two-dimensionally; and a control part which controls the X-Y table and the laser light source.
