Recorder

Abstract

Abstract PURPOSE:To clearly form an image on a photosensitive recording medium without causing sagging of a transparent member and facilitate maintenance, by containing a printing head and a platen in a supported condition in a containing part provided at a position other than an exposure position. CONSTITUTION:A platen 3 is disposed opposite to a thermal head 1, and is pressed against the thermal head 1 to clamp a thermal recording paper 6 therebetween. A shaft of the platen 3 arranged to run idle so that the platen 3 is driven to rotate by a frictional force between the platen 3 and the paper 6 as the head 1 is fed. During printing and exposure, the paper 6 is fixed by clamping it through moving fixing members 4a, 4b and 5a, 5b formed of an elastic material in the directions of arrows. After formation of a mask original plate by printing, the head 1 is moved into a space A provided in the exterior of an exposure range as a containing part, and be readied until an exposure process is finished. The recording paper 6 in a range between X and Y inclusive of an exposure range is prevented from sagging.
