ABSTRACT:
1. Disk player with a magazine
2.1. A known compact-disk player with a magazine consisting of several superimposed compartments for accommodating compact disks has a system of levers and a pulley driven by an electric motor in each compartment for removing a disk from the compartment.
2.2. To decrease the considerable expense for each compartment (2) in the magazine (11), there is an access opening (15) on the rear wall of each compartment, through which a plunger (4) can travel to thrust the compact disk (7) out of the compartment. The plunger can be a flexible shaft that extends forward from the rear wall of the magazine through a tubular guide (3) and along one side of the magazine. The plunger can be introduced into and extracted from the compartment by means of a toothed rack (14) secured to the front of the flexible plunger (4) in conjunction with the cogwheel (10) that is driven by an electric motor (6) and engages the rack.
2.3. When embodied in a compact-disk player the invention is especially appropriate for installation in a motor vehicle.
2.3. Figures 1 and 2.
