<p>PROBLEM TO BE SOLVED: To adjust a positional deviation of a sensor unit for detecting the coordinate of a coordinate detector.SOLUTION: A sensor position adjustment mechanism 400 comprises: a position adjustment bracket 410 fixed to a printed wiring board 362 of a first optical sensor unit 360; a screw insertion part 420 protruding toward a tip of the position adjustment bracket 410; and an adjustment screw member 520 inserted into the screw insertion part 420. Rotational operation of the adjustment screw member 520 in a tightening direction displaces the screw insertion part 420 of the position adjustment bracket 410 to a front side (Za direction). Rotational operation of a head 522 of the adjustment screw member 520 in a loosening direction displaces the screw insertion part 420 to a rear side (Zb direction) by a pressing force (spring force) of a coil spring 530. Displacement of the screw insertion part 420 of the position adjustment bracket 410 in the Za and Zb directions adjusts a roll angleθin an emission direction of infrared of a light receiving/emitting sensor 300 of the first optical sensor unit 360.</p> |
