Abstract
Abstract Photographic printing apparatus for printing a relatively large print and one or more relatively small prints of a single negative and of a predetermined size ratio in side-by-side relationship on a print paper. The apparatus includes a film carrier and a print paper support. A relatively short focal length lens device is provided for receiving light transmitted through the frame of a film carried on the film carrier and focusing it on print paper positioned on the print paper support to form a relatively large image for printing the relatively large print. Light re-directing means is provided for receiving light transmitted through the film frame and directing it around the relatively short focal length device and one or more relatively long focal length lens devices are provided for receiving such light and focusing it on the print paper to form one or more relatively small images adjacent the relatively large image to print the relatively small prints and to thereby enable the relatively large and relatively small prints to be printed side-by-side on the print paper to conserve print paper and minimize the amount of print paper trimming required.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
212 words
Photographic printing apparatus for printing relatively large and relatively small prints of predetermined size ration disposed adjacent one another on print paper, said apparatus comprising: a film carrier; a print paper support spaced from said film carrier for positioning said print paper; light means for projecting light through film positioned on said film carrier and onto print paper on said print paper carrier; a relatively short focal length lens device for receiving image light projected through a frame of said film to direct said image light along a selected optical pAth to focus a relatively large image on said print paper to print said relatively large print; light re-directing means for receiving light projected from said light means and re-directing it to project at an angle to said selected optical path to be projected around said relatively short focal length lens device and be directed toward said print paper; and a relatively long focal length lens device for receiving light from said light re-directing means to focus a relatively small image on said print paper adjacent said relatively large image to print said relatively small print adjacent said relatively large print whereby said relatively large and relatively small prints of predetermined size ratio may be printed simultaneously in relatively close spaced relationship.
Claim 2
Dependent Claim
212 words
Photographic printing apparatus for printing relatively large and relatively small prints of predetermined size ration disposed adjacent one another on print paper, said apparatus comprising: a film carrier; a print paper support spaced from said film carrier for positioning said print paper; light means for projecting light through film positioned on said film carrier and onto print paper on said print paper carrier; a relatively short focal length lens device for receiving image light projected through a frame of said film to direct said image light along a selected optical pAth to focus a relatively large image on said print paper to print said relatively large print; light re-directing means for receiving light projected from said light means and re-directing it to project at an angle to said selected optical path to be projected around said relatively short focal length lens device and be directed toward said print paper; and a relatively long focal length lens device for receiving light from said light re-directing means to focus a relatively small image on said print paper adjacent said relatively large image to print said relatively small print adjacent said relatively large print whereby said relatively large and relatively small prints of predetermined size ratio may be printed simultaneously in relatively close spaced relationship.
Claim 3
Dependent Claim
90 words
Photographic printing apparatus as set forth in claim 1 wherein: said light re-directing means includes a pair of reflectors arranged in spaced relationship with one of said reflectors having a reflective surface disposed in the path of light projected from said light means and through said film frame and the other reflector having a reflective surface disposed in the path of light reflected from said first reflector to direct said light through said relatively long focal length lens device and onto said print paper to form said relatively small image.
Claim 4
Dependent Claim
35 words
Photographic printing apparatus as set forth in claim 1 wherein: said relatively long focal length lens device includes a plurality of lens sets for focusing a plurality of relatively small images on said print paper.
Claim 5
Dependent Claim
52 words
Photographic printing apparatus as set forth in claim 1 that includes: an opaque light mask mounted adjacent said print paper carrier and formed with a frame defining apertures for passage of light to print said prints, the frame around said apertures blocking light to said print paper to form well-defined print borders.
Claim 6
Dependent Claim
35 words
Photographic printing apparatus as set forth in claim 2 wherein: said relatively short focal length lens device includes a plurality of lens elements for focusing a plurality of relatively small images on said print paper.
Claim 7
Dependent Claim
53 words
Photographic printing apparatus as set forth in claim 2 that includes: an opaque light mask mounted adjacent said print paper mount and formed with a frame defining apertures for passage of light to print said prints, the frame around said apertures blocking light to said print paper to form well defined print borders.
