Abstract

A television receiver has an enlarged and projected picture. The object of image in the focal plane of the projection lens is produced by a conventional receiver (5). The receiver (5) has been modified such that its tube (7) gives an inverted picture. An enclosure (4) is attached to the receiver (5). The enclosure (4) supports a projection lens (3), so that a real image of the picture on the TV screen can be thrown onto a wall or screen suitable for films or slides.
