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: an assembly formed by assembling the lens holder together with a conductive body and comprises a circuit that receives supplied power; a shake correction drive section configured to displace the assembly by a shake correction magnet and a shake correction coil disposed at a position facing the shake correction magnet in collaboration with each other; and a position detection section configured to detect a position of the assembly in the direction orthogonal to the optical axis, wherein: the shake correction magnet is disposed around the lens holder, and the shake correction magnet, the shake correction coil and the position detection section are disposed at respective positions shifted in the direction of the optical axis with respect to each other.

主权项

1. A lens drive apparatus for use in a small camera module, which displaces a lens holder in a direction of an optical axis and a direction orthogonal to the optical axis in collaboration with a magnet and a coil, the lens drive apparatus comprising:
an assembly that is formed by assembling the lens holder together with a conductive body and comprises a circuit that receives supplied power; a base that is disposed at a position spaced from the assembly and has an aperture through which the optical axis passes; a plurality of suspension wires that are disposed around the aperture and support the assembly such that the assembly is displaceable in the direction orthogonal to the optical axis; a shake correction drive section configured to displace the assembly by a shake correction magnet and a shake correction coil disposed at a position facing the shake correction magnet in collaboration with each other; and a position detection section configured to detect a position of the assembly in the direction orthogonal to the optical axis, wherein: the plurality of suspension wires include a first suspension wire configured to supply power to the circuit, and a second suspension wire configured to supply power to the circuit via a path different from that of the first suspension wire, and the shake correction magnet is disposed around the lens holder, and the shake correction magnet, the shake correction coil and the position detection section are disposed at respective positions shifted in the direction of the optical axis with respect to each other.
