Abstract

PURPOSE:To prevent abrasion, etc., from being generated due to deviation, play, or friction by eliminating a clearance or a frictional part, by providing a deformable parallel link supporting means which displaces an objective lens and an objective lens holding member in a focusing direction, and a hinge which supports a movable part in such a way that it can be rocked in a tracking direction. CONSTITUTION:The deformable parallel link supporting means 20 to displace the objective lens 14 and a lens barrel 15 in the focusing direction is constituted of the lens barrel 15, flat members 18 and 21, the hinges 18a, 18b, 21a, and 21b, and an intermediate supporting member 23. On the lens barrel 15 side of the intermediate supporting member 23, a support body 16 is arranged extensively, and the tip part of the supporting body 16 corresponding to the position of center of gravity of the movable part 41 is linked to a U-shaped strut being studded on the upper plane of a substrate 17 via a bendable hinge 16a, and the hinge 16a supports the movable part 41 in the tracking direction in such a way that it can be rocked. As a result, it is possible to remove the frictional part or the clearance, and to prevent the deviation, the play, or the abrasion, etc., from being generated.
