ABSTRACT:
A display device arranged to present selectively three different displays. The displays are formed by three sets of display panels with two of the panel sets being selectively movable as a unit relative to the third and movable relative to each other and to the third to provide the selectively different panel displays. Selective movement of the panel sets is effected by a control which, in the illustrated embodiment, includes a camming element which is guided in a plurality of angularly related paths to effect the desired selective disposition of the different panel sets.
