Patent ID: 7416308

Claim:
A projector comprising: a support structure; a light source supported by said support structure for emitting light along an optical axis; an image medium, carrying a plurality of images, supported by said support structure in the path of light emitted along the optical axis by said light source, such that light from said light source may pass through an image carried by said image medium thereby to project an intermediate image; an image dispersion element mounted in fixed position within said support structure in the path of the intermediate image, said image dispersion element having a plurality of reflective surfaces that simultaneously redirect the intermediate image in a plurality of different directions from the projector to produce a plurality of final images; and an image medium driver that drives said image medium relative to said light source, such that at least some of said plurality of images carried on said image medium move into the path of light emitted by said light source, thereby to project a plurality of intermediate images that move relative to said image dispersion element, which in turn simultaneously redirects the moving intermediate images in a plurality of different directions to produce a plurality of final moving images, wherein said image dispersion element redirects the intermediate images such that at least one of the plurality of final images is projected along an axis substantially parallel to the optical axis of the light source.
