ABSTRACT:
A photosensitive lithographic printing plate supplying apparatus includes a first suction device, which sucks an upper surface of an uppermost photosensitive lithographic printing plate of photosensitive lithographic printing plates stacked such that respective photosensitive surfaces thereof face downward and which raises the uppermost photosensitive lithographic printing plate, a second suction device, which sucks the upper surface of the raised uppermost photosensitive lithographic printing plate so as to support the photosensitive lithographic printing plate at one end thereof, and a rotating device which rotates the photosensitive lithographic printing plate supported on one end by the second suction device so that a photosensitive surface of the photosensitive lithographic printing plate faces upward. Accordingly, the photosensitive lithographic printing plates are supplied to an exposure device without the photosensitive surfaces thereof being contacted.
