Patent number: 6590855Abstract: A disk player according to the present invention comprises a magazine and a player portion. When a disk is played, the magazine is loaded in the player portion. A plurality of plates on which disks are to be put are stacked in the magazine. Each of the plates can be separated from each other by not sliding but moving upward and downward. In this separated state, a pickup arm which is equipped with a pickup and a chucking mechanism enters a portion between the plates. After the entrance, the plates in steps above the selected disk further rise, and the plate on which the selected disk falls. By the fall, the selected disk is put on a disk table in the chucking mechanism. Thereafter, a claw member protrudes from the disk table, to clamp the selected disk through a center hole of the selected disk. The necessity of a member for rotatably pressing the selected disk from above is eliminated. Consequently, the disk player can be made thin.Type: GrantFiled: January 25, 2001Date of Patent: July 8, 2003Assignees: Sanyo Electric Co., Ltd., Tottori Sanyo Electric Co., Ltd.Inventors: Tadanori Tamiya, Shinichi Aoki
