<p>PROBLEM TO BE SOLVED: To provide a hand tremor correction unit that enables a correction lens to be highly accurately positioned, and moreover is compact and enables reduction in costs.SOLUTION: A hand tremor correction unit has: a stationary frame 3 that is anchored inside a lens barrel 13; a lens frame 2 that holds a correction lens, faces the stationary frame 3 when viewing in an optical axis direction and is movably supported in a plane orthogonal to an optical axis; magnet members 51a, 51b and 51c that are held by the lens frame 2 and have drive magnets 511a, 511b and 511c; cores 520a, 520b and 520c that are held by the stationary frame 3; and three axial gap type linear motors 5a, 5b and 5c that include drive coils 524a, 524b and 524c wound around center core parts 521a, 521b and 521c, and move the lens frame 2 in a plane surface orthogonal to the optical axis. In an FPC 7 attached to the stationary frame 3, hall elements 61a, 61b and 61c are mounted, and in an optical axis direction, the hall elements 61a, 61b and 61c, the magnet members 51a, 51b and 51c, and the drive coils 524a, 524b and 524c are arranged in this order.</p> |
