Abstract

PURPOSE:To simplify a movable part in structure and to easily obtain various magnifications, by moving only a printing board block along the optical axis of an optical system, and changing a total track. CONSTITUTION:A printing board black is composed of a printing board 23 which is used for exposing a rolled printing paper 16 while the paper 16 is kept temporarily by the printing board 23, an easel mask 25 installed on the printing board 23 with a clearance, a feed roller 26 installed at the right end of the printing board 23, etc. Moreover, the printing board 23 is fitted in such a way that it is moveable upward and downward by guide posts 7 and 8 and moved along the optical axis of the optical system by a driving means, so that the enlarging magnification is changed. Therfore, structure of the moveable part is simplified and, at the same time, various magnifications are easily obtained.
