Abstract

There is provided a camera module including: a housing unit; a lens unit which is movable relative to the housing unit in an optical axis direction and directions perpendicular with respect to an optical axis; and an actuator unit moving the lens unit, wherein corners of the housing unit are provided with flat surfaces which are inclined with respect to an optical axis of the lens unit.

Claims

1. A camera module comprising:

a lens unit;

an actuator unit configured to move the lens unit; and

a housing unit configured to accommodate the lens unit therein,

wherein corners of the housing unit are provided with flat surfaces which are inclined with respect to an optical axis of the lens unit, and

wherein the lens unit further comprises

a first frame configured to move relative to the housing unit in an optical axis direction,

a second frame configured to move relative to the first frame in a first direction perpendicular with respect to the optical axis, and

a third frame configured to move relative to the second frame in a second direction perpendicular with respect to the optical axis, and wherein the first frame, the second frame, and the third frame are configured to substantially move directly along guide grooves.

2. The camera module of claim 1, wherein the flat surfaces of the corners have an inverted triangular shape.

3. The camera module of claim 1, wherein corners of the first frame are provided with flat surfaces which are inclined with respect to the optical axis of the lens unit.

4. The camera module of claim 1, further comprising ball members disposed between the first and second frames and between the second and third frames.

5. The camera module of claim 1, wherein the second frame comprises first guide grooves disposed on a top surface and recesses disposed directly below the first guide grooves on a bottom surface.
