| 20110058268 | Lens driving device - 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. | 03-10-2011 |
| 20100232042 | Lens driving device - In the present invention, a lens driving device has appropriate offset for miniaturization, excellent linearity of driving current versus displacement, and good displacement sensitivity. A casing holding a yoke with at least one permanent magnet mounted on an inner circumference thereof is connected with a lens holder having a driving coil installed on an outer sidewall thereof between an upper spring member and a lower spring member. When the driving coil is not powered, the lens holder props against the casing at a side opposite to an imaged object. When the lens holder props against the casing, the position of the driving coil along Z axis causing a magnitude of driving magnetic field intersecting with the driving coil is 50%˜90% of a maximum value of the driving magnetic field intersecting with the driving coil while the lens holder moves toward the imaged object. | 09-16-2010 |
| 20100214681 | Lens driving device - A lens driving device is provided to reduce a number of required high-accuracy components and also eliminate the unevenness of maximum displacement of a lens holder with respect to a base. An outer edge of a lower spring plate is clamped by a lower casing served as a base and a lower spacer. A first protrusion is formed on a sidewall of the lens holder and protruding outward therefrom. A second protrusion protruding toward the lens holder is formed on an inner circumference of the lower spacer and extends to a position above and separating from the first protrusion by a distance S. The first protrusion props against the second protrusion when the lens holder is moved toward an imaged-object side and reaching a displacement of the distance S. | 08-26-2010 |
