An ommateal image projector of a type, in which a single or a plurality of rows of the so-called bar lenses having a longer length in the direction of its optical axis than the effective lens diameter thereof are arranged, each bar lens projecting a partial image of an object to be projected onto a mirror surface, and the partial image formed on this mirror surface forming again this partial image onto the image projecting surface by the same bar lens. The entire image of the object is formed on the projecting surface by row of the bar lenses, and the total image thus formed is an erected image.
