PURPOSE:To provide a range-finding device which can execute the range-finding of plural points in a picture by the minimum light projection elements without deteriorating the accuracy of focusing. CONSTITUTION:A light projecting lens 14 projecting light by the optical path of a short focal length by reflecting the range-finding light successively emitted from the plural light projection elements 11 by a movable mirror 13, and a light projection lens 15 projecting the light by the optical path of a long focal length by reflecting the range-finding light successively emitted from the elements 11 by a mirror 12 are juxtaposed. Then, the range-finding light whose projecting angle is different is projected on a photographic field and the range- finding of the plural points are executed. |
