Abstract
A stocker box stocking a plurality of CDs and a player box adjacent to the stocker box are disposed next to each other. Each of the boxes has an opening on a side wall so as to oppose to an opening formed on a side wall of the adjacent box. A horizontal guide rail device is provided in each box, extending to the opening thereof. A horizontal carrier is provided to be moved along the guide rail devices of the stocker and second player boxes passing through the openings. A plurality of coils are mounted on each of the guide rail devices, arranged in a moving direction of the horizontal carrier. The horizontal carrier has a magnet to form a magnetic field passing through some of the coils. The coils are sequentially excited so as to move the carrier in the moving direction.
