PURPOSE:To execute exactly cutting positioning by executing simultaneously an exposure for forming a positioning projecting part, at the time of a relief exposure, forming the positioning projecting part without any other device, and utilizing it. CONSTITUTION:A positioning projecting part 19 is provided on only one side in one direction of the (x) direction or the (y) direction of a photosensitive resin sheet for printing, a stopper 22 is provided on a position where when it descends, its tip part 22a is made to press-contact with the positioning projecting part 19 in case when the photosensitive resin sheet for printing is drawn by putting the positioning projecting part 19 in the rear and is positioned at a cutting position on a positioning plate 20, and the descent of the stopper 22 is executed after passing through a relief part 14c. Accordingly, when the photosensitive resin sheet for printing is placed on the positioning plate 20 and is drawn by a drawing tool 21, the tip part 22a of the stopper 22 is made to press- contact with the positioning projecting part 19 formed in the rear and is stopped. As a result, cutting positioning of the photosensitive resin sheet for printing can be executed exactly. |
