PROBLEM TO BE SOLVED: To allow components of a coordinate input device to be efficiently and easily adjusted.SOLUTION: A first housing and a second housing incorporate sensor units which are provided with a plurality of light projection parts including a first light projection part and a second light projection part different in distance from an input surface as light projection parts projecting light to input surfaces in parallel and light-receiving parts receiving light respectively. Retroreflection parts are mounted on side surfaces in a longitudinal direction different from mounting surfaces mounted on the input surfaces. So as to individually light the plurality of light projection parts, light projection configurations by the first light projection part and the second light projection part are controlled. A light-receiving state in the light-receiving part of the first housing by light projection from each of the first light projection part and the second light projection part of the second housing is determined. On the basis of the determination result, posture adjustment information about the sensor unit is generated. |
