    • An ultra-compact projection television receiver is disclosed comprising cabinet means for enclosing the components of the receiver. The receiver has vertically arranged elevatable rear projection screen means selectively storable in the receiver. Means are included for elevating the screen means from a first receiver-inoperable position wherein the screen means is stored in the cabinet and the receiver is substantially as compact as a conventional large-screen console television receiver. In a second, elevated receiver-operable position, the screen means is emerged from the cabinet and is capable of displaying an image with an area greater than three times the image area on a conventional console television receiver.
