There is disclosed a superimpose device for a single-lens reflex camera, which has a finder optical system including a focusing screen, a pentagonal roof type prism, and an eyepiece lens, a reflection plate which is arranged near the prospective imaging plane the finder optical system, and has micro-prisms forming a display portion, a plurality of light sources arranged near the vertex of the prism, and a projection optical element for deflecting illumination light from each light source by a reflection surface, and projecting the deflected light toward a front upper portion of the prism. The display portion illuminated with the illumination light via the prism, and light reflected by the display portion is guided to the eyepiece lens.
