Abstract Transparency display devices to display bound books of transparencies include a translucent screen mounted in a frame which is at a substantial angle to the horizontal plane when the translucent screen is arranged for viewing. A light source is provided behind the translucent screen and a transparency book support is arranged to oscillate to and from proximity with a margin of the screen to facilitate the removal of transparencies from viewing position to storage position. Two modifications of this support are shown, which respectively oscillate and reciprocate. Two support cabinets include one capable of being folded into a relatively flat package for transportation, and one permanent cabinet having storage for the transparencies in the form of tracks to receive the ring binder portion of the book while allowing the transparencies to hang in a protected place. One version of the transparencies has an aperture at each corner of its free margin. The support cabinet has a stud which supports the transparency when the aperture is placed over the stud, the stud being removable automatically when the support is reciprocated to simultaneously release the free margin of the transparency and to pull the support away from the translucent screen to permit the transparency to return of its own weight to its storage position. A method of changing displayed transparencies by moving a support for a binder of transparencies away from a translucent display screen, returning the support to the vicinity of the screen margin and inverting another transparency about the binding to overlie the translucent display screen is also disclosed.
A transparency display device for handling and displaying large substantially nonresilient flexible transparencies, the combination comprising a translucent illuminated panel substantially vertically oriented for display; a frame having a horizontal support rod movably mounted adjacent to a horizontal margin of said translucent illuminated panel for substantially horizontal movement toward and away from said translucent illuminated panel a book of a plurality of large substantially nonresilient flexible transparencies having a pair of rigid covers and having a loose-leaf binding on one edge such that said transparencies and said rigid covers may swing about said binding through substantially a full circle, and said book being suspended over said horizontal support rod with said binding resting on said horizontal support rod and said covers hanging freely from said binding on opposite sides of said horizontal support rod to stabilize said book on said support rod and said transparencies freely suspended from said binding on either side of said horizontal support rod said horizontal support rod is an inverted U-shaped member having a horizontal top member and vertical legs extending down from ends of said top member, and is mounted behind said translucent illuminated panel; and said vertical legs are pivotably mounted at their bottom ends to swing said horizontal top member toward and away from a top margin of said translucent illuminated panel.
