ABSTRACT:
A device for projecting and magnifying a picture image from a television set. A first housing is removably mounted to the television set to receive the picture image from the television screen. A second housing is slidably mounted to the first housing and cooperatively with the first housing forms a passage through which the picture image passes to a lens mounted at the end of the second housing. The first housing includes a light-absorbent inner surface whereas the second housing includes a light-reflective inner surface. A gear and rack device is provided for slidably adjusting the second housing relative to the first housing and controlling the ratio of the light-reflective surface to the light-absorbent surface. A barrel-configured lens is slidably mounted to the second housing for focusing of the picture image on a remotely located viewing surface which may be positioned at any one of a number of different distances from the television set and lens.
