Objective lens drive device for optical pick-up

An optical pickup objective lens driving device, comprising a blade mounted on the blade has an objective lens, a plurality of elastic support members for supporting the blade and capable of elastically moving with respect to the blade, and a servo mechanism for along and lower, left and right, and the direction of rotation of the driving blade. The elastic support member is composed of the elastic support member, and arranged with respect to the rotation center of the blades facing each other, the same distance between each pair of the elastic support member. Accordingly, by virtually eliminating the difference between the amount of deformation of the elastic support members supporting the blade tilt control, when a small impact or vibration is applied or generated, the elastic supporting member is prevented from moving in any direction. Thus, the objective lens is controlled to achieve a stable position.
