Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
179 words
A process camera for printing pictures of different sizes in the desired display positions on a photosensitive materials, comprising: (a) an object holder on which an object to be photographed is mounted and which includes a light for illuminating the object; (b) a photosensitive material holder on which a photosensitive material is mounted; (c) a lens holder for holding a lens which focuses the object onto the photosensitive material, wherein these three holders are aligned in series on and along a light axis of the lens, wherein the lens holder is positioned between the object holder and the photosensitive material holder, wherein the object holder is movable towards and away from the lens holder, and wherein the photosensitive material holder is movable in x and y directions perpendicular to the light axis; and (d) a plurality of register pins and respective drive means for positioning the objects of different sizes, which are mounted to the object holder so that each of the register pins may be independently projected through or beyond the object holder by the respective drive means.
