摘要： In an angle detecting apparatus and projector using range finder units, range finding calculations are performed in plural directions using line type passive range finders as the range finding units. An average value of inclination angles calculated based on the range finding calculations is selected as the inclination angle. Thus, if one range finding result has an abnormal value, the adverse effects thereof are reduced and the structure is miniaturized.
