LENS DRIVING DEVICE

摘要

Disclosed is the specific constitution of a lens driving device capable of driving a lens in an optical axis direction and of compensating for shaking. A lens driving device (1) is provided with a first holding body (2) which holds the lens and can move in the optical axis direction (the Z direction), a second holding body (3) which holds the first holding body (2) so as to allow movement in the Z direction, a fixed body which holds the second holding body (3) so as to allow movement in a direction approximately orthogonal to the Z direction, a first driving magnet (23) for driving the first holding body (2) in the Z direction, a second driving magnet (25) for driving the second holding body (3) in the X direction, and a third driving magnet (27) for driving the second holding body (3) in the Y direction. The first holding body (2) is supported by the second holding body (3) so as to allow movement in the Z direction by means of a first supporting member (8, 9), and the second holding body (3) is supported by the fixed body so as to allow movement in a direction approximately orthogonal to the Z direction by means of a second supporting member (10). The first driving magnet (23), the second driving magnet (25), and the third driving magnet (27) are fixed to the fixed body.
