Abstract: The present embodiment relates to a lens driving device comprising: a base; a first holder disposed on the base; a second holder disposed inside the first holder; a first coil and a first magnet which move the second holder in an optical axis direction; a second coil and a second magnet which move the first holder in an x-direction or a y-direction perpendicular to an optical axis; and a first ball disposed between the top plate of the base and the top plate of the first holder, wherein the first ball guides the first holder to move relative to the base in the x-direction and the y-direction perpendicular to the optical axis.

Abstract: The present embodiment relates to a lens driving device comprising: a housing; a lens holder disposed within the housing; a first magnet disposed in the housing; a second magnet disposed on the lens holder; a first coil that moves the first magnet in an optical axis direction through interaction with the first magnet; a second coil that moves the second magnet in a direction perpendicular to the optical axis through interaction with the second magnet; a first ball disposed between the housing and the lens holder, and a wire movably supporting the lens holder relative to the housing.

Abstract: The first exemplary embodiment of the present invention relates to a lens driving device, comprising: a housing; a lens holder disposed within the housing; a first magnet disposed on the housing; a second magnet disposed on the lens holder; a first coil moving the first magnet to an optical axis direction through interaction with the first magnet; a second coil moving the second magnet to a direction perpendicular to the optical axis through interaction with the second magnet; a first ball interposed between the housing and the lens holder; and an elastic member connecting the housing and the lens holder.
