Television projector










Image Number 4 for United States Patent #4074322.

Television picture image projecting apparatus removably attached to a standard television receiver and including a housing having an image entrance opening adjacent the receiving screen, a Fresnel lens in the housing for enlarging the received image, and a mirror combination in the housing including two plane reflecting mirrors joined together with the reflecting surfaces defining an included angle of ninety degrees for inverting a received image. The mirror combination is located optically between the lens and an image exit opening adjacent the other end of the housing, and the resulting image is projected on a planar viewing surface such as a standard projector screen in a forward projection mode. In another aspect, a plane reflecting mirror is located optically between the lens and mirror combination, and the resulting image is projected on one surface of a translucent screen for viewing from the opposite surface in a rear projection mode. In another aspect, a plane reflecting mirror is located optically between the television screen and the lens, and the resulting image is projected on a viewing surface in a forward projection mode.
