Abstract
An optical recording head which decomposes light emitted from a light source into three primary colors with rotation of a color wheel, emits the light linearly through an optical fiber array, illuminates an optical valve array through an integrator and an illuminating optical element array and exposes a photographic paper to light modulated by the optical valve array through an imaging optical element array. The integrator is formed by arranging two mirrors in parallel to each other, and a rod lens is provided between the mirrors. The rod lens has a refracting power to decrease the divergent angle of the light emergent from the optical fiber array.
