Abstract
A compact disc program display mechanism in which album covers are displayed on pages similar to a book presentation; each album having a selection indicia visually associated therewith for selection by the customer. The several pages are turned in response to energization of an electrical drive motor and gear train, controlled manually by customer accessible push button switches or automatically by a programmed microprocessor. Each energization of the motor serves to pivotally turn a pair of pages in one direction with the indexing movements of the pages being controlled by an opto-switch and the microprocessor for deenergizing the drive motor at predetermined page movement. Reverse movement of the pages is also conditioned by the opto-switch which signals the micro-processor to reverse the rotational direction of the drive motor. Each page displays album covers on both its front and back sides for customer viewing.
