摘要： Provided is a digitizer apparatus that can prevent mutual interference of irradiation lights emitted from left and right light emitting units and further increase the detection range from 170 degrees. The digitizer apparatus includes: a pair of light emitting units that are installed on both ends in a longitudinal direction of a support member and that scan irradiation light toward a coordinate designation object inserted to a coordinate input surface; a retroreflection member for retroreflection of irradiation light directed from the light emitting units, the retroreflection member surrounding the coordinate input surface; and a pair of light receiving units that receive light of a light shielding image in which reflected light from the retroreflection member member and the irradiation light from the coordinate designation object inserted to the coordinate input surface are shielded, the digitizer apparatus detecting an inserted coordinate position of the coordinate designation object on the coordinate input surface, wherein the pair of light emitting units are installed at positions with different axes of irradiation lights from the light emitting units across an optical axis center plane in the pair of light receiving units.
