Title:
LENS DRIVE DEVICE, CAMERA MODULE, AND CAMERA MOUNTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/172163
Kind Code:
A1
Abstract:
Provided are a lens drive device, a camera module, and a camera mounting device, with which a reduction in size and weight can be achieved and reliability can be increased. The lens drive device comprises: a shake correction fixed unit; a shake correction movable unit that is capable of swinging within a plane orthogonal to an optical axis; a shake correction support unit that supports the shake correction movable unit in a state in which the shake correction movable unit is separated in the optical axis direction from the shake correction fixed unit; and a drive source that swings the shake correction movable unit. One of the shake correction fixed unit and the shake correction movable unit has a projection part that projects in the optical axis direction. The other of the shake correction fixed unit and the shake correction movable unit has a flat part that abuts the projection part. The projection part and the flat part slide relative to each other during shake correction. The projection part is elastically displaceable in the optical axis direction.
