    摘要: An object lens driving device causes partial rotation of movable members holding an object lens on an X-Y frame perpendicular to the optical axis of the object lens about a resilient hinge member as a fulcrum. The movable members are supported by base members. The hinge member interconnects the movable members and the base members. Electro-magnetic coils and magnets effectuate relative rotation of the movable members with respect to the base members about the hinge member. A rotational axis passing through the hinge member also passes through the position of center of gravity of the movable members and the balanced position of moment of inertia of the movable members.

    摘要: An objective lens-driving unit comprising a lens supporting means for supporting the objective lens having an optical axis vertical to a recording medium on which light beams converge through the objective lens so as to attain optical recording, optical playing and optical erasing of information on the recording medium; at least one driving means for driving said lens supporting means in the tracking direction; a driving means for driving said intermediate supporting means in the focusing direction, wherein said tracking direction-driving means comprises a magnetic circuit that produces magnetic flux in the circumferential direction of the recording medium, and a tracking direction-driving coil that is positioned to cross a gap formed in the magnetic circuit to thereby receive an electro-magnetic force due to an interaction between the magnetic field of the magnetic circuit and the current passing through said coil, said tracking direction-driving coil being positioned within the excitation area of the magnetic circuit even when said coil moves in the focusing direction.
