This is a multi-functional stereo movable picture enlarger. It can automatically control the exposure and pass-over of a film, enlarge and print many parallel spaced pictures on the same photographic paper to form stereo movable pictures when covered by a film. In the present invention, a grating plate, its controller, and a film presser are added to an existing enlarger. The grating plate converges the rays passing through the negatives and projects them in parallel onto the printing paper. The grating controller controls precisely the displacement of the grating plate. The presser presses an enlarging film matching the grating plate onto the developed picture. Thus a stereo movable picture is obtd.. The present enlarger is advanced and reasonable in construction, its operation is convenient. It is fit for automatic flow process, and the picture printing is completed once for all. |
