发明名称 Device for projecting two separate images using a single light source and - has central housing for the light source
摘要 A device, which projects two separate images using a common light source, consists of a central housing in which the light source is installed. The housing has tubular expansions projecting from opposite sides. The housing is provided with slots for slides or transparencies and each extension is provided with a lens system. The light rays pass through the slides or transparencies and project an image on each of two parallel surfaces. Mirrors may be fitted to the ends of the extensions so that one image is projected on to the ceiling and the other image is projected on to the floor. The central housing is made from round aluminium extrusions or castings. USE/ADVANTAGE - Device for projecting two separate images from a single light source.
