摘要： A disk stopper (101) for regulating a loading position of the disk stopper, a stopper regulating member (102) that regulates a movable range of the disk stopper (101), and a link member (103) movable in association with the stopper regulating member (102), and a cam slider (30) engageable with the link member (103) are provided. When a small-diameter disk is inserted, the first engaging portion of the link member (103) and the first engaging portion of the cam slide (30) engage each other. When a large-diameter disk is inserted, the second engaging portion of the link member (103) and the second engaging portion of the cam slide (30) engage each other. Based on the engaging condition of the link member (103) and the cam slider (30), the stopper regulating member (102) switches the loading position of the disk medium regulated by the disk stopper (101).

摘要： An optical disk device (1) includes a feed gear (64) that engages a rack portion (57a) 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.

摘要： An optical axis angle adjusting device is provided, which can adjust the optical axis angle, which can prevent sound skipping or noise in the image of the optical reproduction device even when the disk has certain surface undulation. In the adjusting device, an adjustment disk 10 is inclined relative to the turn table. Rotation phases of the disk are detected, and incident angle is detected at the respective rotation phases. The optical axis angle is adjusted so that the incident angles at the respective phases are identical with each other. Because the disk is inclined, the incident angle can be detected accurately, and the optical axis adjustment can be achieved accurately.
