  • Patent number: 8325242
    Abstract: An image stabilizing apparatus may include a fixing member disposed to a lens assembly having a through hole of which a center coincides with an optical axis of the lens assembly, a moving member disposed to move perpendicular to the optical axis with respect to the fixing member having a lens holder projecting in a direction of the optical axis to hold a compensating lens, a driving portion causing the moving member to move in a first direction perpendicular to the optical axis and in a second direction perpendicular to the optical axis and the first direction, four position determining portions formed in the first direction and the second direction on an outer circumferential surface of the lens holder of the moving member, and four stoppers projecting from an outer circumferential surface of the through hole of the fixing member to the moving member.
    Type: Grant

  • Patent number: 7065295
    Abstract: An apparatus for driving a lens in a camera includes a lens module installed in a reciprocating and sliding manner in an inside of a lens barrel, a lead screw installed on the lens barrel, for being rotated by a driving motor, and a power transferring member assembled on the lens module and equipped with a tooth-shaped part that corresponds to a tooth shape of the lead screw. The lens module has a lens and a slider having a mounting unit for mounting the lens and receiving the power transferring member in a movable manner. The mounting unit has a through groove in which one end of the power transferring member is fit and supported and a slit groove in which the other end of the power transferring member is fit to be supported for being movable in a direction perpendicular to the movement direction of the slider.
