Abstract
A plurality of different advertising messages is displayed in a mechanical and repetitive manner. The size of the message is determined by the number of moveable panels used. A complete message can be shown on as little as two moveable panels or as many as an even multiple of two panels. Each panel is rectangular in shape and mounted with the long edge vertical. Each pair of panels are moved sequentially, first longitudinally and then transversely until a new message is displayed. The process is repeated sequentially to display each new message in turn. The total number of panels is determined by the number of messages and the size of each message to be displayed with each panel being located on a moveable carrier. The carriers are prevented from twisting and jamming by discrete springs and transfer guides that maintain a preferred relationship of the carrier when being moved.
