发明名称 Optical Disk Device
摘要 An optical disk device ( 1 ) includes a feed gear ( 64 ) that engages a rack portion ( 57 a) integrally formed with an optical pickup ( 57 ), a tray gear ( 13 ) used for vertically moving a turntable ( 52 ) and moving a disk tray ( 12 ), and a motor ( 62 ) as a common driving source. The number of teeth of the feed gear ( 64 ) is the same as the number of teeth of the tray gear ( 13 ), and the rotation is transmitted from the feed gear ( 64 ) to the tray gear ( 13 ) so that the ratio of the number of rotations of the feed gear ( 64 ) to the number of rotations of the tray gear ( 13 ) is 1:1. With such an arrangement, it becomes possible to perform a pickup feeding operation, a turntable vertically-moving operation, and a disk carrying operation by one driving source, and it becomes possible to enhance ease of assembly.
