ABSTRACT:
A camera range finder provides a first shielding member, secured to a frame, for urging light-emitting means toward a projection lens and covering an outer periphery of the light-emitting means; and a second shielding member, secured to the frame, for urging light-emitting means toward a light-receiving lens and covering an outer periphery of the light-receiving means. The respective shielding members have both shielding and urging functions for the light-emitting and light-receiving means. In a simple configuration, the light-emitting means and light-receiving means can secure both positional adjustment and electromagnetic shielding.
