Lens driving device, camera module and camera mounting device having shake-correcting function and auto-focusing function

摘要

The lens driving device is provided with a driving unit for OIS, using a driving force of a first voice coil motor to enable an OIS movable unit to swing in a plane orthogonal to the optical axis direction with respect to an OIS fixed unit; a driving unit for AF, using the driving force of a second voice coil motor to enable an AF movable unit to move along the optical axis direction with respect to an AF fixed unit; a supporting unit for OIS, formed of a first elastomeric material, and having a first biaxial hinge structure moveably supporting the OIS movable unit in the plane orthogonal to the optical axis direction; and a supporting unit for AF, formed of a second elastomeric material, and having a second biaxial hinge structure moveably supporting the AF movable unit along the optical axis direction.
