Abstract
An audiovisual device for displaying a visual image while simultaneously sounding out a corresponding audio message. The device includes base unit and a number of cartridges which fit into the base unit. Each of the cartridges includes a housing featuring a window, a pair of substantially parallel rods which are rotatably mounted within the housing, and a printed substrate, such as paper or plastic, mounted on the rods so that the substrate can be scrolled for the purpose of displaying portions of the substrate through the window in the housing. The base unit includes a driving mechanism for engaging and rotating the rods of the cartridge and a frame locator system for accurately locating a selected portion of the substrate in the window. Finally, the base unit includes a suitable speaker for producing sounds corresponding to the displayed portion of the substrate.
