Lens holder drive apparatus, and camera equipped therewith

摘要

Provided is a small, low-profile lens holder apparatus. A lens holder apparatus includes: a lens holder to which a lens section can be attached; a first drive section that moves the lens holder in a first direction along the optical axis; a second drive section that moves the lens holder in a second direction and/or third direction that are perpendicular to the optical axis and differ from each other; 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 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 third direction of the lens holder with respect to the base.

1. 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 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.
