<p>An illuminated transparency viewing device is supported by a leg construction which may be adjusted to orient the viewer at different angles relative to a supporting surface. Two pairs of spaced apart legs are provided, each leg being pivotally mounted to the viewer housing for movement between retracted and extended positions so that either pair may be retracted or extended to tilt the viewer on edge. Each pair of legs may be of different length than that of the other pair. One leg of each pair is conlinearly arranged with a corresponding leg of the other pair to define a pair of leg assemblies. Each leg assembly therefore has a pair of legs, each being mounted for pivotal movement between the side walls of a U-shaped bracket secured to the bottom of the viewer housing and may be extended from or retracted into the bracket.</p> |
