Abstract

A camera device including a mover including a first magnet; a lens; a stator including a first coil; a first substrate; a second substrate movably disposed on the first substrate; an image sensor disposed on the second substrate; a second coil disposed on the first substrate; and a second magnet disposed on the second substrate and facing the second coil is provided. The second substrate includes a coupling part coupled to the image sensor, and an extension part extending outwardly from the coupling part so that at least a portion thereof overlaps with the first substrate in the optical axis direction, and the camera device further includes a ball disposed between the first substrate and the extension part of the second substrate.

First claim

What is claimed is:
