| 20090284850 | DEVICE AND METHOD FOR LOCKING LENS - A device and a method for locking lens in a lens holder are provided, wherein the lens is configured in a voice-coil motor (VCM) of a camera module of a cell phone and the VCM has a lens holder for a lens being fixed inside. The device includes a circumgyration stop instrument having a bottom surface for urging against the top surface of the lens holder for preventing a lateral stress and a lateral movement from occurring on the lens holder while the circumgyration stopping unit is coupled with the lens holder. | 11-19-2009 |
| 20090284851 | DEVICE AND METHOD FOR LOCKING LENS - A device for locking lens and a method for the same are provided. The device is used in a voice-coil motor of a photographing module of a cell phone. The voice-coil motor has a lens-stand for a lens being turned to a locking depth inside. The device includes a circumgyration-stop instrument having a first sustaining surface, and a focusing ring having a turning end. A turn-locking length of the turning end is equal to the locking depth inside. The device includes a circumgyration-stop preventing a pressure being persisted to apply on the lens as the focusing ring finishes the turn of the lens. The first turn-stop surface props the first sustaining surface as the focusing ring is turned to an extremity of the turn-locking length. The focusing ring accordingly escapes the circumgyration-stop instrument for finishing the focusing of the lens in the lens-stand. | 11-19-2009 |
