摘要： This lens drive device 1 comprises: an autofocus drive unit for performing autofocus using a driving force of a voice coil motor configured from a first coil part 112 and a magnet part 122; and a shake correction drive unit for performing shake correction using a driving force of a voice coil motor configured from a second coil part 231 and the magnet part 122. The magnet part 122 includes first magnets 122A, 122C disposed at two mutually facing sides among the four sides of a substantially rectangular-shaped lens drive device in a plan view, and a second magnet 122B disposed at another side. The side the second magnet 122B faces is designated a no-magnet disposed section R where no magnet is disposed.

摘要： A lens drive device is provided with: an AF drive unit that has an AF coil unit disposed around a lens unit and an AF magnet unit disposed separately in the radial direction with respect to the AF coil unit and automatically carries out focusing; and an OIS drive unit that has an OIS magnet unit disposed in an AF unit that includes a movable AF unit and a fixed AF unit and an OIS coil unit disposed separately in the direction of the optical axis with respect to the OIS magnet unit and carries out shake correction. The AF drive unit has an elastic support unit that connects the movable AF unit with the fixed AF unit. The movable AF unit is supported movably both ways in the direction of the optical axis by an elastic member.

摘要： This lens-driving device is provided with: a shake correction drive unit which, utilizing the drive power of a voice coil motor, causes a moveable shake correction unit that includes a shake correction magnet unit to oscillate within a plane orthogonal to the optical axis with respect to a stationary shake correction unit that includes a shake correction magnet unit, in order to carry out shake correction; and a plurality of suspension wires for supporting the moveable shake correction unit with respect to the stationary shake correction unit. The moveable shake correction unit has a retaining member for retaining the shake correction magnet unit, and the retaining member has a wire passage part recessed inwardly in the diametrical direction and formed to have an inside diameter at the bottom which is larger than the inside diameter at the top, a suspension wire being arranged in the retaining member.
