Lens holder drive apparatus, and camera equipped therewith

A lens holder drive apparatus comprising:

• a lens holder to which a lens section can be attached;
• a first drive section including a focusing magnet disposed around the lens holder and a focusing coil disposed so as to face the focusing magnet, and configured to move the lens holder and the focusing coil in a first direction along an optical axis by means of collaborative mutual action of the focusing coil and the focusing magnet;
• a second drive section including a camera-shake correction magnet disposed in a moving part that includes the lens holder and the first drive section and a camera-shake correction coil, and configured to move the moving part and the camera-shake correction magnet in a second direction and/or third direction that are perpendicular to the optical axis and differ from each other by means of collaborative mutual action of the camera-shake correction magnet and the camera-shake correction coil;
• a base printed wiring board that is disposed in a position spaced from the lens holder;
• and
• a position detection section that is connected to the base printed wiring board in order to detect a position in the second direction and/or the third direction of the lens holder and the base printed wiring board.

• a supporting section that includes a base disposed in a position spaced from the lens holder and a supporting member that supports the lens holder so as to be able to move in the second direction and/or the third direction;
• and
• a position detection section that is disposed on the supporting section in order to detect a position in the second direction and/or the third direction of the lens holder with respect to the base, wherein:
• the lens holder is supported so as to be able to move in the first direction by a lens holder supporting section that includes a lens holder supporting frame disposed outside the lens holder and a leaf spring composed of an upper leaf spring fixed to a top of the lens holder and a top of the lens holder supporting frame, and a lower leaf spring fixed to a bottom of the lens holder and a bottom of the lens holder supporting frame;
• the camera-shake correction coil is formed on a coil board, includes a plurality of coil parts spaced from each other in a plane of the coil board;
• and
• the supporting member is a plurality of suspension wires, one of the suspension wires having one end fixed to the base and the other end fixed to the lens holder supporting section and used for power feeding to the first drive section.
