Beschreibung
Zusammenfassung:	A scanning-type distance measuring apparatus includes: a light projector projecting laser beams at predetermined intervals; a light receiver including light receiving elements, receiving a reflected beam of a laser beam that the light projector projects, and outputting a light reception intensity signal of the reflected beam; a scanning operation unit projecting a laser beam projected by the light projector to perform scanning; an integrator integrating, for each light receiving element, time-series light reception intensity signals output by the light receiver when the light receiver receives reflected beams corresponding to the laser beams projected at the predetermined intervals; and a distance calculator calculating a distance to an object for each light receiving element, based on integration that the integrator performs. The integrator integrates one light reception intensity signal output from one light receiving element and integrates one light reception intensity signal output from another light receiving element.
