Abstract: The speed of a disc handling operation by a disc apparatus having disc changer capability is significantly increased and, at the same time, the disc handling operation is performed with stability. In the disc apparatus according to this invention, a plurality of reproducing units loaded with discs are moved independently and disc reproduction is started by returning the reproducing units to their dedicated positions. Simultaneous returning of the plurality of reproducing units is prevented and each reproducing unit moves for refuge while reproducing the disc. This novel setup significantly shortens the time for moving the reproducing units for disc reproduction. When continuously reproducing a plurality of discs accommodated in proximity, the plurality of reproducing units are moved in a stacked state rather than independently. This also contributes to a significant reduction of the time in the disc handling operation.

Therefore, the extension and maintenance of the cartridges can be facilitated. When a double-side reproducing operation is performed, the pickup cartridge is turned upside down and then mounted on the disc apparatus, whereby the double-side reproduction can be surely performed by the disc inverting mechanism. Further, disc inclining means is provided to prevent a disc being returned from the disc feeder to the disc cartridge from abutting against the disc cartridge. The disc inclining mechanism and the disc inverting means may be integrally constructed by the same member to reduce the cost.
