DISPLAY DEVICE WITHIN FINDER SCREEN

摘要

PROBLEM TO BE SOLVED: To provide a display device within finder screen capable of realizing the miniaturization of a single lens reflex camera and appropriate display within a finder screen. SOLUTION: A microprism constituting a range-finding point of an AF (autofocusing) frame is formed on the finder image side surface of an SI (superimposing) screen 2. At least one surface of the microprism is constituted of a cylindrical surface. A light source unit 6 emitting illuminating light and a prism lens for projecting light 8 guiding the illuminating light to the microprism are arranged on the outside of a finder optical path. Superimposing display is performed by reflected light from the illuminated microprism.
