A device for detection of the direction of the viewfinder óoeil in a photographic apparatus.

摘要

Device for detecting the direction of the eye in a photographic camera including a viewer, in which a beam of rays, reflected from an object to be photographed and transmitted via a photographing objective is made incident on the eye of a photographer in order to form an erect image thereof by an image erecting optical element (1). The device comprises a light-emitting optical system (10) and a light-receiving optical system (20), for detecting the direction of the eye, which are arranged so that their optical axes (Ax1, Ax2) lie in a plane perpendicular to the optical axis of the beam of rays incident, through the photographing objective, on the image erecting optical element (1).
