The present invention is a graphic materials display device consisting of a housing (12) containing a source of illumination (20), a number of graphics (18) to be displayed sequentially behind a viewing screen (22), and a programmed motor for operating the mechanism. The graphics can be transparencies, posters, and the like, which are suspended from rods (26), the ends of which ride in shaped channels (30) formed into side members (16) of the housing and are pulled down from above in front of the source of illumination. The ends of the rods are engaged by hooks attached to an endless chain or belt (44) driven by a programmed motor. The rods, and the graphics suspended from them, are stored in a section of the shaped channels which keep them together until they are needed. The graphics removed from the illuminated screen are carried downwards, across the lower portion of the housing, lifted up the rear of the housing and allowed to slide downwards in the shaped channel, where they join other rods in the storage section. |
