Abstract
PURPOSE: To lead the rays of exposure-information-displaying elements into the finder optical path and let them focus near the eye point by using the specified optical guide members.
CONSTITUTION: Rays from exposure information display elements 6a, 6b...such as LEDs or other are reflected on the reflecting surfaces 8c, 8d of an optical guide member 8 and pass through the prism 5 in the finder optical path by the projecting surface 8e formed by cylindrical planes, etc., thence they are converged toward an eye point 1 within the plane parallel to the arraying direction of the elements 6a, 6b... Hence, the information-displaying element rays are led into the finder optical path and are then focussed at the eye point irrespective of the number of the exposure-information-displaying elements, thus exposure information may be visually recognized without moving the eyes. The similar results are also obtainable even by focusing the rays by the use of Fresnel lens or the like.
