Abstract

Disclosed herein is a camera lens module. The camera lens module in accordance with an embodiment of the present invention includes a vibration correction carrier, a rolling unit disposed in parallel to a direction vertical to an optical axis and configured to support the vibration correction carrier, a lens barrel carrier disposed on a side opposite the vibration correction carrier based on the rolling unit, and a base configured to mount the vibration correction carrier and the lens barrel carrier on the base.

First claim

What is claimed is:

1. A camera lens module, comprising: a vibration correction carrier; a lens barrel carrier configured to mount the vibration correction carrier; a base configured to mount the vibration correction carrier and the lens barrel carrier; an automatic focus driving unit disposed between the base and the lens barrel carrier; and a vibration correction driving unit disposed between the base and the vibration correction carrier and placed on an opposite side of the automatic focus driving unit based on an optical axis, wherein, the lens barrel carrier and the vibration correction carrier mounted on the lens barrel carrier move along the optical axis in response to operation of the automatic focus driving unit; and wherein, the vibration correction carrier performs relative motion on a plane perpendicular to the optical axis with reference to the lens barrel carrier in response to operation of the vibration correction driving unit.

2. The camera lens module of claim 1 , wherein the vibration correction driving unit comprises first and second vibration correction driving units disposed in first and second edge regions of the camera lens module, respectively, in parallel to the optical axis.

3. The camera lens module of claim 2 , wherein:
the first vibration correction driving unit comprises a first vibration correction magnet and a first vibration correction coil disposed to face each other in a central direction of the optical axis in the first edge region, and
the second vibration correction driving unit comprises a second vibration correction magnet and a second vibration correction coil disposed to face each other in the central direction of the optical axis in the second edge region.

4. The camera lens module of claim 1 , wherein a distance from the automatic focus driving unit to the central direction of the optical axis and a distance from the vibration correction driving unit to the central direction of the optical axis are equal.

5. The camera lens module of claim 1 , wherein:
the vibration correction driving unit comprises first and second vibration correction driving units, and
the first and the second vibration correction driving units are symmetrically disposed to a virtual perpendicular line drawn from the automatic focus driving unit to the central direction of the optical axis.

6. The camera lens module of claim 1 , wherein the vibration correction driving unit comprises:
at least one vibration correction magnet, and
a yoke unit comprising a plurality of yokes disposed to correspond to the vibration correction magnet.
