ABSTRACT:
A video disc player having a base and a protective cover pivotally hinged on the base and adapted to be opened and closed to permit a disc to be inserted or removed from the rotary drive assembly is provided with a device for automatically turning over a disc carried by the rotary drive assembly as an incident to opening and closing the cover by powered drive units; the turning over includes a ninety degree phase in which the disc slides under its own weight between substantially vertical and horizontal positions while the bottom edge of the disc slides laterally and a ninety degree phase in which the disc pivots about the bottom edge between substantially horizontal and vertical positions; guides are provided on the underside of the cover and the base for guiding both the bottom edge and the top edge of the disc during its sliding movement and for supporting the bottom edge of the disc for pivotal movement about an axis adjacent the pivotal axis of the cover.
