Imaging apparatus

Claim 1

Optical projection apparatus including: a document conveyor assembly adapted to support two transparent documents having different indicia thereon representative, when viewed together, of a composite image, said document conveyor assembly positioned for movement through an object plane, in a first direction, said document conveyor assembly adapted to support the transparent documents disposed one from another along said first direction, a light receiving member positioned at an imaging plane adapted to concurrently receive light images of the transparent documents supported on said document conveyor assembly, two lens means fixedly positioned between said document conveyor assembly and said light receiving member, said lens means being displaced one from another along said first direction, means to move said light receiving member through said imaging plane in a second direction, opposite from said first direction, means to move said document conveyor assembly and, consequently, transparent documents supported thereon through said imaging plane in said first direction whereby each lens is adapted to simultaneously project light images from a single transparent document supported by said document conveyor assembly, illumination means positioned on the side of said document conveyor assembly opposite from said lens means, said illumination means adapted to create light for permitting projecting of light rays from transparent documents supported by said document conveyor assembly to said imaging plane, light condensor means positioned between said illumination means and said document conveyor assembly and being adapted to concentrate the light created by said illumination means, light baffle means, fixedly positioned between said document conveyor assembly and said lens means, said baffle means having a pair of slots transverse to said first and second mentioned directions of motion, each slot being adapted to restrict the amount of light projected to said image plane from each transparent document, and programming means to actuate said means to move said document conveyor assembly and said means to move said light receiving member in a correlated fashion whereby flowing images of transparent documents supported on said document conveyor assembly are concurrently projected to said light responsive member so that a unitive composite image may be created thereat.
