た事を特徴とするフアインダー内表示装置。[Claims for Utility Model Registration] A main mirror that separates the light flux from the subject toward the photoelectric conversion means and the light flux toward the finder system through transmission and reflection, and an information display section on or near the intended image formation plane of the objective lens. Further, an illumination means for illuminating the information display section through the main mirror is provided, and a light irradiation area on the main mirror of the illumination means is separated from a passage area on the main mirror of the luminous flux guided to the photoelectric conversion means. In the viewfinder display device set as follows, the region where the light beam of the light irradiation region passes through the main mirror and irradiates the main mirror receiving member is made into a mirror surface.
