LENS DRIVE APPARATUS, CAMERA MODULE AND CAMERA |
| 摘要 |
A lens drive apparatus that displaces a lens holder in a direction of an optical axis and a direction orthogonal to the optical axis comprises: a drive section that displaces an assembly, which is formed by assembling a lens holder displaceable in the direction of the optical axis together with a magnet disposed around the lens holder, in the direction orthogonal to the optical axis by the magnet and a coil disposed at a position facing the magnet in collaboration with each other; and a Hall device that is disposed at a position shifted in the direction of the optical axis with respect to the coil and detects a position of the magnet in the direction orthogonal to the optical axis. |

1. A lens drive apparatus that displaces a lens holder in a direction of an optical axis and a direction orthogonal to the optical axis, the lens drive apparatus comprising:
a drive section that displaces an assembly, which is formed by assembling a lens holder displaceable in the direction of the optical axis together with a magnet disposed around the lens holder, in the direction orthogonal to the optical axis by the magnet and a coil disposed at a position facing the magnet in collaboration with each other; and a Hall device that is disposed at a position shifted in the direction of the optical axis with respect to the coil and detects a position of the magnet in the direction orthogonal to the optical axis. |
