LENS DRIVE DEVICE WITH HAND TREMOR CORRECTION FUNCTION

摘要

PROBLEM TO BE SOLVED: To provide a lens drive device with a hand tremor correction function that can obtain excellent driving efficiency even when an inner-side periphery of an oscillation coil or an outer-side periphery thereof changes in a radial direction of a base substrate.SOLUTION: A lens drive device with a hand tremor correction function comprises: an autofocus unit that causes a lens to move in an optical axis direction with a subject side set at a forward side of the optical axis direction of the lens; and a hand tremor correction unit that causes the autofocus unit to oscillate in a direction orthogonal to the optical axis direction. The autofocus unit is mounted to an outer periphery side of the lens, and comprises: a focus coil that is wound around the optical axis; and a magnet which is arranged on the outer periphery side of the focus coil, and of which a magnetic pole surface opposes the focus coil in a radial direction at a space apart from the focus coil. The hand tremor correction unit comprises an oscillation coil that is wound around the optical axis, and opposes the magnet in the optical axis direction at a space apart from the magnet. The magnet is magnetized in a direction where the magnet is rotated around the optical axis and around an axis vertical to a normal line of the magnetic pole surface.SELECTED DRAWING: Figure 2
