Document Type and Number:
Japanese Patent JP6712070
Kind Code:
B2
Abstract:
To provide a lens driving device, a camera module and a camera mounting device that can improve OIS sensitivity and that can further facilitate an assembly operation, while keeping high reliability.SOLUTION: A lens driving device comprises a shake correction driving unit that performs shake correction by rocking a shake correction movable unit relative to a shake correction stationary unit in a plane being orthogonal to an optical axis direction utilizing driving force of a voice coil motor, and the shake correction driving unit comprises an AF driving unit that automatically focuses by moving an AF movable unit relative to an AF stationary unit in the optical axis direction utilizing the driving force of the voice coil motor. A shake correction supporting unit of the shake correction driving unit is formed of an elastomer material and has a two-axis hinge structure that movably supports the shake correction movable unit in the plane being orthogonal to the optical axis. An AF supporting unit of an AF driving unit is formed of the elastomer material and has a two-axis hinge structure that movably supports the AF movable unit in the optical axis direction.SELECTED DRAWING: Figure 6
