Abstract: A position detecting device includes a timing generating unit, light-emitting units, a light-receiving unit, a demodulating unit, an integrator, and a computation unit. The timing generating unit repeatedly and separately generates modulated signal streams of different phases at intervals.

Abstract: A position detecting device includes light-emitting units, a light-receiving unit, an AD conversion unit, a position detecting unit, and an offset unit. The light-emitting units emit optical signals that are intensity-modulated using modulated signal streams of different phases. The light-receiving unit receives light reflected on an object and converts the reflected light into an analog signal. The position detecting unit detects a position of the object based on a digital signal converted by the AD conversion unit. The offset unit offsets a direct-current voltage level of the analog signal output from the light-receiving unit by an offset level, and outputs the analog signal to the AD conversion unit. The offset unit adjusts the offset level so as to cause an average of the analog signal input to the AD conversion unit to approach a median of an input voltage range of the AD conversion unit.
