Camera lens module

1. A camera lens module, comprising:

an optical image stabilizing carrier configured to accommodate a lens barrel and driven by an optical image stabilizer driving unit;

a rolling unit configured to support a plane motion of the optical image stabilizing carrier to be orthogonal to an optical axis;

an autofocus carrier configured to mount the optical image stabilizing carrier to advance and retreat along the optical axis at a side opposite to the optical image stabilizing carrier;

a base including side surfaces configured to wrap the autofocus carrier and the optical image stabilizing carrier,

wherein the optical image stabilizer driving unit is placed between the base and the optical image stabilizing carrier and an autofocus driving unit for driving the autofocus carrier is placed between the autofocus carrier and the base,

wherein the rolling unit further includes:

two or more balls placed between the optical image stabilizing carrier and the autofocus carrier to support the optical image stabilizing carrier so that the optical image stabilizing carrier moves in a direction vertical to the optical axis;

two or more supporting pieces respectively provided at a corner of the autofocus carrier in one piece and having a concave accommodating surface formed on a top surface thereof;

two or more seating pieces formed on a circumference of the optical image stabilizing carrier in a projected form to be correspondent to the supporting pieces and respectively having a concave accommodating surface formed on a bottom surface thereof; and

wherein the balls are interposed between the supporting piece and the seating piece so that a first portion and another portion of the balls are respectively accommodated on the accommodating surfaces of the supporting piece and the seating piece, and

wherein the supporting piece and the seating piece are arranged to be vertically stacked in an optical axis direction to form a single shake suppressing piece, and two or more concave surfaces shaped so that the shake suppressing piece is inserted therein are provided along the optical axis direction inside a corner of the base.

2. The camera lens module according to claim 1 ,

wherein the autofocus driving unit includes:

an autofocus magnet installed on an outer surface of the autofocus carrier; and

an autofocus coil installed at the base to face the autofocus magnet.

3. The camera lens module according to claim 2 ,

wherein the autofocus driving unit includes:

optical axis guide devices respectively including a ball and arranged at the base corresponding to both left and right sides of the autofocus magnet; and

a back yoke arranged on a rear side of the autofocus magnet.

4. The camera lens module according to claim 1 ,

wherein the optical image stabilizer driving unit includes:

a coil installed on the base; and

a magnet installed on the optical image stabilizing carrier to face the coil.

5. The camera lens module according to claim 1 ,

further comprising an image sensor module mounted on a bottom of the base, wherein the image sensor module includes:

an infrared filter arranged at a center of an opening of the bottom unit of the base;

a filter base on which the infrared filter is installed; and

a substrate arranged under the infrared filter and having an image sensor installed thereto.
