ABSTRACT:
A distance measuring apparatus of an apparatus having a moving mechanism includes: a speed detector; and a mechanism responsive to a moving speed signal supplied from the speed detector which varies a focus lens position and a focal length of a light receiving optical system, a scanning range of a light projecting optical system, a base length, a position where light axes of a pair of light receiving optical systems or light axes of the light receiving and light projecting optical systems cross with each other, or responsive to a moving direction signal supplied from a moving direction detecting means of the apparatus having the moving mechanism which changes a measurement direction of a field of view. Thus, optimal measurement accuracy and a field of view to be measured can always be provided even though the moving speed or the moving direction of the apparatus having the moving mechanism is varied.
