Camera lens module for mobile terminal

Abstract

A camera lens module includes: an external case; an Automatic Focusing (AF) driver disposed at one surface of the external case to guide a lens carrier along an optical axis, the AF driver having a magnet and a coil arranged to face each other in parallel to the optical axis; and first and second OIS drivers located opposite the AF driver with the lens carrier as the center, each of the first and second OIS drivers having a coil and a magnet arranged to face each other in parallel to the optical axis in a vertical or horizontal direction to correct shaking of the lens carrier, wherein each of the OIS drivers and the AF driver includes a position sensor opposed to the magnet.

What is claimed is: 
     
         1 . A camera lens module comprising:
 an external case;   an Automatic Focusing (AF) driver disposed at one surface of the external case to guide a lens carrier along an optical axis, the AF driver having a magnet and a coil arranged to face each other in parallel to the optical axis; and   first and second OIS drivers located opposite the AF driver with the lens carrier as the center, each of the first and second OIS drivers having a coil and a magnet arranged to face each other in parallel to the optical axis in a vertical or horizontal direction to correct shaking of the lens carrier,   wherein each of the OIS drivers and the AF driver includes a position sensor opposed to the magnet.   
     
     
         2 . The camera lens module of  claim 1 , wherein each of the position sensors disposed at the OIS drivers and the AF driver is located at an opening of the corresponding coil to face each magnet. 
     
     
         3 . The camera lens module of  claim 1 , wherein the first and second OIS drivers are located at first and second corner regions of the camera lens module. 
     
     
         4 . The camera lens module of  claim 3 , further comprising:
 an OIS carrier which houses the lens carrier and is arranged inside the external case,   wherein the first OIS driver comprises:   a first OIS magnet mounted at an outer circumferential surface of the OIS carrier and disposed to face the first corner region; and   a first OIS coil disposed at the first corner region and disposed to face the first OIS magnet in a state separated from the first OIS magnet, and   wherein the second OIS driver comprises:   a second OIS magnet mounted at another outer circumferential surface of the OIS carrier and disposed to face the second corner region; and   a second OIS coil disposed at the second corner region and disposed to face the second OIS magnet in a state separated from the second OIS magnet.   
     
     
         5 . The camera lens module of  claim 4 , wherein the OIS carrier is supported by an OIS base positioned at the bottom. 
     
     
         6 . The camera lens module of  claim 5 , wherein the OIS base comprises first and second upright portions which are respectively provided at two corners to be housed in the first and second corner regions and to support the first and second OIS coils, respectively. 
     
     
         7 . The camera lens module of  claim 6 , wherein the first position sensor is disposed at the first upright portion, and the second position sensor is disposed at the second upright portion. 
     
     
         8 . The camera lens module of  claim 7 , wherein the first position sensor is disposed on an inner surface or a rear surface of the first OIS coil in the first corner region, and the second position sensor is disposed on an inner surface or a rear surface of the second OIS coil in the second corner region.
