Abstract
An optical distance measuring device includes: a light source unit that irradiates a measurement region with irradiation light; a light receiving unit that has a light receiving surface including a plurality of light receiving elements capable of receiving reflected light from a range including the measurement region corresponding to irradiation with the irradiation light and outputs a signal corresponding to a light receiving state of the reflected light for each of the light receiving elements; and a measurement unit that measures a distance to an object in the measurement region by using the signal outputted from the light receiving unit. The light receiving unit has a function of selecting a light receiving element that outputs the signal so that a light receiving position at which the reflected light is received is variable, and the light receiving unit changes the light receiving position to a plurality of positions with respect to a position of the reflected light.
