ABSTRACT:
An eye direction detecting apparatus of a camera having a view finder in which a bundle of rays reflected from an object to be photographed and transmitted through a taking lens is made incident on a photographer's eye to form an erect image thereof by an image erecting optical element. The apparatus includes a light emitting optical system which emits measuring light to be made incident upon the photographer's eye through a part of the view finder, and a light receiving optical system which receives light reflected from the photographer's eye to detect the eye direction. The light emitting optical system and the light receiving optical system are arranged so that optical axes thereof lie in a plane normal to an optical axis of a bundle of rays incident upon the image erecting optical element through the taking lens.
