The disclosure is directed to an extremely compact camera-processor which is configured to sharply reverse the direction of the exposed light sensitive sheet as it leaves the exposure plane. The light sensitive sheet is thereafter driven downwardly into a processor bath along with a relatively flimsy receptor sheet.

A contact screen positioning device supports a flexible bowed halftone screen over a vacuum platen having a sheet of film thereon so that as the positioning device moves slowly down over the vacuum platen, central portions of the contact screen initially press against central portions of the platen and less and less centralized portions thereafter sequentially press against less and less centralized portions of said vacuum platen, to produce a rapid sweeping of air toward outer portions of the platen for rapid positioning of said screen over said platen without entrapped air pockets being formed between the screen and the film on the platen.

A roller wick is positioned to transmit moisture in an uphill direction by capillary action from a roller wick reservoir to an inked paper roller drive means. A thicker relay wick transmits relatively large amounts of fluid from a relay wick reservoir, positioned higher than the roller wick reservoir, to the roller wick reservoir. The relay wick itself is positioned over the roller wick reservoir so that any drippings therefrom are deposited within the roller wick reservoir.

A transport mechanism is disclosed for driving inked paper emerging from the printing station of a duplicating machine into a stacking station, the transport mechanism employing a first pair of beveled drive rollers and a second pair of rounded rollers biased against the beveled drive rollers by gravity which prevents ink buildup upon the second pair of drive rollers where bleed edge inked paper is being transported through the system.

Inked paper transport mechanism employing a pair of beveled rollers

A printing station including an impression cylinder and a plate cylinder is positioned adjacent an air applicator which causes paper emerging from the nip of the cylinders to be pressed against an arcuate portion of the impression cylinder so as to be driven over a paper guide means which forwards the paper to a stacking station. Drive means are also included adjacent the guide means, consisting of a pair of beveled rollers which produce stiffening of the paper to give it rigidity along its length in order to support the paper in cantilever fashion as it passes from the drive means to the stacker. The air applicator is designed to produce some air travel in the direction of motion of the inked paper to assist in driving the paper and drying the ink.
