PURPOSE:To facilitate operation for dismounting a photosensitive plate and to enhance operation efficiency, by moving a photosensitive plate holder automatically from a printing position to this side by a specified mechanism, turning it inside out, and returning it again to the printing position. CONSTITUTION:The support shaft 15 of a photosensitive plate holder 14 is inserted into the long holes 19 of lever rods 21A and 21B, and the holder 14 is slidably mounted with an air cylinder 22, the gear 25 of the shaft 15 is engaged with a worm gear 30, and turned with a motor 26. After printing has been finished, locking is released, the cylinder 22 is actuated to move the holder to this side, the motor 26 is actuated to turn it inside out, it is returned again to the printing position, and locked. These sequential actions are automatically conducted through limit switches 29, 30, etc., and a given relay circuit. The photosensitive plate is exchanged before the next printing, thus permitting mounting and dismounting operations to be made easy and its efficiency to be enhanced. |
