ABSTRACT:
An improved television system and apparatus is provided in which a large size image is projected from the face of a cathode-ray tube viewing screen to a larger display screen. The display screen is mounted in an essentially vertical position on top and to the rear of a cabinet. A television receiver is mounted within the cabinet, and an optical system is provided which projects an enlarged image from the viewing screen of the television receiver to the enlarged display screen. The optical system includes a mirror positioned in a drawer, which is mounted in the cabinet, and which may be opened to draw the mirror into the proper position so that an enlarged image is projected over the entire surface of the display screen. The apparatus has the feature of being of a relatively narrow width, especially when not in use and when the drawer is closed.
