Abstract
A recording unit has an illuminating device for projecting light on an original to form an original image, and an optical device which focuses the original image formed by the illuminating device. A light control plate has a slit for allowing a portion of the original image focused by the optical device to pass through. The light which passes through the slit of the light control plate is guided onto a print head which ejects ink on a recording medium when exposed to the light.
