Abstract

Abstract A scanning head and a recording head supported against a subject copy and a record medium wrapped side-by-side around a single rotary drum in relationship are caused to move synchronously in opposite directions, either away from or toward each other, parallel to the axis of the rotary drum in relation with the rotation thereof. A record of the subject copy thus reproduced on the record medium is reversed as to its left and right, so that the record medium can be used as a master in lithographic and other printing processes.
