Abstract

A lens moving apparatus includes a first lens moving unit including a bobbin having a first coil mounted at an outer circumference thereof, a first magnet being opposite to the first coil, and a housing for supporting the first magnet, and a second lens moving unit including a base, a plurality of support member pairs for supporting the housing such that the housing is movable relative to the base, and a second coil opposite to the first magnet, wherein each of the support member pairs includes first and second support members separated from each other, the first and second support members being disposed at the same side of the housing in a state in which the first and second support members are adjacent to each other, and power is supplied to the first coil through a first support member pair, which is one of the support member pairs.

Description

technical field [0001] Embodiments relate to a lens moving device and a camera module including the same. Background technique [0002] It is difficult to apply technology related to a voice coil motor used in a conventional general camera module to a low power consumption type mini camera module. For this reason, studies related thereto have been actively conducted. [0003] A camera module mounted in a small-sized electronic product such as a smartphone may be frequently shaken during use. In addition, the camera module may slightly shake due to shaking of the user's hand during shooting. Therefore, a technology capable of installing an optical image stabilizer in a camera module is very necessary. [0004] Much research has been done on optical image stabilizers. A technology capable of moving an optical module along an x-axis and a y-axis perpendicular to an optical axis has been proposed for an optical image stabilizer. According to this technique, the optical syst...
