Abstract
In an image-reproducing system in which a number of parallel light beams contribute to the formation of half-tone dot areas on a record medium and scan over the record medium together, a reversing prism is included in the beam path to permit the line fit or line overlap to be closely controlled. The prism also adjusts the spacing between beams in the scanning direction which is provided when a coherent light source is used to avoid interference between adjacent beams.
