  • Patent number: 5353152
    Abstract: A screen projection apparatus includes a housing within which a pair of projection screens are stored in a rolled position on motor driven rollers. A pair of access doors are mounted on the housing and support an idler roller over which a screen passes. The access doors open, one at a time, and the idler roller ensures that each of the screens when unrolled hangs in a common plane thereby eliminating the need to refocus the optical projection equipment which is used with the apparatus.
