Abstract
Abstract A camera-processor magazine is disclosed having a cartridge for storing light sensitive roll material, together with means for driving such material out of the cartridge and upon an exposure platen. A roller curtain for shielding the material when the magazine is open also functions to guide the leading portion of the roll material across the exposure platen and into the nip of a pair of exit rollers.

Claim 1
Independent Claim
162 words
A photosensitive material positioning system for transporting photosensitive material from a cartridge to an exposure platen comprising: a. means for lowering a light curtain over said exposure platen; b. means for driving said material from said cartridge while directing the leading edge of said material at an acute angle relative to the plane of said light curtain so that said material becomes straightened out by said light curtain and travels along said curtain in contact therewith while being driven by said drive means, thereby to eliminate photosensitive material guide means which would be otherwise positioned adjacent said exposure platen in front of said platen; c. means for raising said light curtain after final positioning of said material upon said platen to enable exposure thereof to a light image; d. a pair of exit drive rollers for driving said material off of said exposure platen; and e. exit drive roller control means for selectively opening and closing the nip between said roller pair.
