  • Patent number: 4185898
    Abstract: A projector for projecting images of an image bearing film which has marginal edges and a central image bearing portion, comprises a film guide which includes vertically spaced, substantially cylindrical guide members. The image bearing film is guided radially to the periphery of said guide and is passed around the peripheries of the guides with the marginal edges engaged thereon and the image bearing portion disposed between the guides. A light source is arranged centrally of the guides and its rays pass through the image bearing film to a cylindrical interceptor surface which is arranged radially outwardly of the guide. The light source is advantageously arranged in connection with a rotary slotted housing in which the slots are spaced circumferentially around its periphery and project the light rays periodically to the image to give moving image effect.
