摘要： A photographic projection apparatus for use with a film unit which has a plurality of images formed in a plurality of arcuate rows thereon supports the film unit between a light source and an optics system, both of which move along an arcuate path corresponding in shape to that of the arcuate rows of images on the film unit. The film unit is intermittently moved in a direction normal to the scan of the image rows so as to provide a sequential scan of the images in successive rows whereupon the images are projected onto a screen.
