ABSTRACT:
A pair of illuminated transparency viewers may be mounted on a supporting frame assembly so that one viewer generally provides a horizontally oriented viewing surface and the other viewer generally provides a vertically oriented viewing surface. The frame assembly includes a base portion adapted to receive the legs of one of the viewers and an upright portion adapted to receive the legs of the other viewer. The base portion and the upright portion each have a U-shaped cross section to define an open channel into which the respective legs of the viewers are inserted and secured by appropriate means. Two frame assemblies are utilized to mount the viewers which have two leg assemblies, each of which, in turn, has a leg pivotally mounted for movement between retracted and extended positions.
