  • Patent number: 6922928
    Abstract: A multi-picture frame includes a picture panel having a front transparent surface, a casing having a receiving chamber mounted at a back of the picture panel, a picture film rotatably supported in the casing and adapted for being view from the front transparent surface of the picture panel, a light source disposed in the receiving chamber of the casing, a moving picture frame mounted between the picture panel and the light source, comprising a rolling device mounted in the casing and a shader slide arranged to be rotatably driven by the rolling device, and an electric input electrically connected the light source and the moving picture frame to a power source respectively. Therefore, the light source generates light which is adapted for passing through the shader slide to the picture film so as to reflect a moving image of the shader slide on the picture film.
