PROBLEM TO BE SOLVED: To realize lightening and miniaturization, to precisely obtain focus and tracking response of a lens holder for control drive force and to sufficiently display control performance. SOLUTION: A lens holder 101 holds a lens 102 in its hollow, and further, is supported by slender arms 103a, 103b, 104a, 104b, and these arms are supported by support plates 107, 108 also. The base parts of the support plates 107, 108 are held to a hold body 109. The arms 103a-104b allow that the lens holder 101 is controlled in the optical axial direction, and the support plates 107, 108 are allowed to be moved by controlling in the tracking control direction. The arms 103, 104 are prolonged along the tracking control direction, and are provided with a flat surface in the Y direction, and are provided with rigidity for other directions excepting the focus drive direction to stabilize the attribute of the lens holder. |
