    摘要: Position information of a first sensor unit and a second sensor unit is calculated using angle information of peaks calculated from a light amount distribution having a plurality of peaks detected by light-receiving unit of the second sensor unit from light emitted by light-emitting unit of the first sensor unit. The coordinates of a pointed position are calculated based on the position information of the first sensor unit and the second sensor unit and a change in a received light amount distribution that occurs due to a pointing to a coordinate input region detected by the light-receiving units. Here, the light-emitting units of the respective multiple sensor units are arranged in known positions relative to the light-receiving units.
