A section of the bottom of the case shall be a door equipped with a hinges so that it opens and closes automatically with the lowering and rising of the picture surface. When the picture surface is being lowered, the door will drop open by gravity. When the picture surface is being raised, the two ends of the slat in the bottom pocket of the screen fabric will engage two hooks on the door to lift it to the closed position where a limit switch will cut off the electrical current to the screen. The balance of the bottom of the case is a second hinged door with manual opening to provide access. Hinges are mounted to allow matching of the doors to the ceiling.
