Abstract: An optical member supporting device is described that includes, in an XYZ rectangular coordinate system, spherical bodies, a first holding portion and a second holding portion, an optical member held by the first holding portion or the second holding portion, first yokes protruding from the first holding portion facing the second holding portion, and second yokes protruding from the second holding portion facing the first holding portion and opposed to the first yokes in a predetermined direction in the X-Y direction. The first holding portion and second holding portion extend in an X-Y direction and are opposed in a Z direction with the spherical body interposed therebetween. The second holding portion includes a second magnet and the first yokes and the second yokes are opposed to the second magnet in the Z direction.

Abstract: A lens driving device and the lens holder cannot tilt when the lens holder moves up due to the coil energized. The inside holding portion (14a) of the front spring member (14A) is connected to the surface of the +Z side of the front connection portion (13b) of the lens holder (13), the inside holding portion (14a) of the rear spring member (14B) is connected to the surface of the +Z side of the rear connection portion (13c), the outside diameter of which is larger than the outside diameter of the front connection portion (13b), the outside holding portion (14b) is connected with the base (12) in the manner of shifting the inside holding portion (14a) towards the ?Z side, so as to apply the pressure of the ?Z-axis direction to the lens holder (13).

Abstract: A lens driving device can not increase the manufacturing cost, and the lens holder can not tilt when the lens holder moves up due to the coil energized. The inside holding portion (14a) of the front spring member (14A) is connected to the surface of the +Z side of the front connection portion (13b) of the lens holder (13), the inside holding portion (14a) of the rear spring member (14B) is connected to the surface of the +Z side of the rear connection portion (13c), the outside diameter of which is larger than the outside diameter of the front connection portion (13b), the outside holding portion (14b) is connected with the base (12) in the manner of shifting the inside holding portion (14a) towards the ?Z side, so as to apply the pressure of the ?Z-axis direction to the lens holder (13).

Abstract: The present invention provides a shake correction device which can not generate the hysteresis phenomenon and can suppress unnecessary resonance and improve endurance with respect to drop impact. In this shake correction device, the eddy current induction plate 16a of +Z side is opposite to and has a gap with the surface (14a) of the +Z side of the permanent magnet (14) which is arranged to wind around the optical axis at an interval of 90 degree in the Z direction, the eddy current induction plate 16b of radial direction is opposite to and has a space with the surface (14b) of the outside in the radial direction, and the eddy current induction plate 16c of the periphery direction is opposite to and has a gap with the surface (14c) in the periphery direction.

Abstract: This invention provides a lens driving device with a driving coil connected thereto that can avoid possible damages on the ends of the driving coil and any adverse effect on the spring members or the lens holder. When the ends of the driving coil are connected to the electric terminals mounted on a casing respectively, the coiling pull start section of the driving coil which begins from the beginning end of the driving coil to the electric terminal and the coiling pull finish section of the driving coil which begins from the finish end of the driving coil to the electric terminal are made into L-shaped structures. Such L-shaped structure comprises a lens holder lateral section extending horizontally and a terminal lateral section extending vertically.
