11A to 11C are views schematically showing a state in which a rotation holder according to the first embodiment of the present invention is rotated about a first axis, and FIGS. 12A to 12C are a holder according to the first embodiment of the present invention. Is a view schematically showing a state that is rotated about the second axis.

Referring to FIGS. 11A to 11C, when rotating about the first axis (X axis), the rotating plate 1130 rotates while riding on the first ball bearing 1131 in which the ball bearings are arranged along the first axis (X axis). As a result, the rotating holder 1120 is rotated together (in this case, the rotating holder 1120 does not move relative to the rotating plate 1130). In addition, referring to FIGS. 12A to 12C, when rotating based on the second axis (Y axis), ride the second ball bearing 1133 in which the ball bearings are arranged along the second axis (Y axis) and the rotation holder 1120 ) Is rotated (in this case, since the rotating plate 1130 does not rotate, the rotating holder 1120 is moved relative to the rotating plate 1130).

As shown in the drawing, when rotating about the first axis (X axis), the second ball bearing 1133 aligned with the second axis (Y axis) cannot move while being inserted into the seating groove. This is because when the structure is rotated based on the second axis (Y axis), the first ball bearing 1131 aligned with respect to the first axis (X axis) cannot be moved while being inserted into the seating groove.

The light whose path is changed by the reflection module 1100 is incident on the lens module 1200. Therefore, in the plurality of stacked lenses provided in the lens module 1200, the optical axis is aligned with the Z axis, which is the direction in which light is emitted from the reflection module 1100. In addition, the lens module 1200 includes a second driving unit 1240 to implement AF and zoom functions. In addition, since the lens module 1200, which is relatively light since it does not include other components for camera shake correction, is moved in the optical axis direction to implement the AF and zoom functions, power consumption can be minimized.

The lens module 1200 includes a lens holder 1220 provided in an inner space of the housing 1010, a lens holder 1220 including a laminated lens therein, and a second driving unit 1240 for moving the lens holder 1220 Includes.
