ABSTRACT:
A plate making machine of a compact size has a mechanism for dealing with jamming, by which jammed master paper can be easily removed, and the maintenance of an exposure stage and a supply transfer system can be performed without disassembling the machine body. The supply transfer system for feeding the master paper X to the exposure stage 9 is provided in a generally horizontal direction at an upper portion of the plate making machine body 1. A lamp house 13 for projecting the original image is provided above the exposure stage 9. An exposure plate 24 is provided at the exposure stage 9, and the exposure plate is tiltable about tilting shaft 25 provided at the side thereof opposite to the supply transfer system. An endless feed belt 33 for feeding and discharging the master paper X relative to the exposure plate 24 is provided in surrounding relation to the exposure plate 24. A discharge transfer system is provided in a slanting manner below the supply transfer system, and the discharge transfer system takes up the master paper X, subjected to exposure, from the exposure plate 24 so as to develop and fix the latent image when the exposure plate 24 is in a tilted position.
