Abstract
A position detecting device and method implemented therein that is able to accurately detect an indicated position even when a water droplet or the like is formed upon the position-detecting-device's surface. The device includes: a light-guide plate placed upon a displaying surface of a displaying device; an emitting unit for emitting light beams that are totally reflected thickness-wise within the light-guide plate, so as to scan along the sides of the light-guide plate in an X-axis and a Y-axis direction under the control of an emission-control unit; an indicating device; and a coordinate calculating unit. In the indicating device, a light-guiding part guides light traveling within the light-guide plate into a detection unit, which detects the guided light in order to output a detection signal. The coordinate calculating unit calculates a coordinate position by deriving a scanned position from the detection signal and the emission-control unit.
