US 5,313,334 A · Objective lens moving actuator

Abstract

An objective lens moving actuator comprises a movable member for supporting an objective lens, a resilient supporting member for resiliently supporting the movable member together with the objective lens such that the movable member having the objective lens can be moved in a first direction parallel to the optical axis of the objective lens and in a second direction perpendicular to the optical axis of the objective lens, a fixing member to which the base end of the resilient supporting member is fixed, an electromagnetic drive device for moving the resilient supporting member in the first and second directions together with the objective lens, and an adjusting member for rotating the resilient supporting member such that the optical axis of the objective lens has a predetermined skew angle.
