发明名称 PHOTOGRAPHIC PRINTING APPARATUS
摘要 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.
