  • Patent number: 4437248
    Abstract: A toy television receiver has a light-diffusing screen curved about a small light bulb, approximating a punctiform source of radiation, which transluminates a transparent carrier of positive images such as an endless film strip or a string of slides. The carrier can be manually advanced by being mounted on one or two reels or on a drum rotatable with the aid of a knurled wheel, which projects from the housing of the device, or by being juxtaposed with an externally manipulable pressure roller.
