Abstract: A camera lens assembly providing focal length adjustment to permit mounting in a personal portable terminal. The camera lens assembly includes a lens assembly; a driving unit provided in one side of the lens assembly; and a guide section provided between the lens assembly and the driving unit, wherein the lens assembly moves forward and backward in a direction of an optical axis to the driving unit by guidance of the guide section. The guide section enhances an auto-focusing function and simplifies mounting of the camera lens assembly, rendering it possible to secure portability even when a camera is mounted to a miniaturized personal portable device such as a mobile communication terminal, a portable computer or the like.

Abstract: An optical image stabilizer for use in a camera lens assembly includes: a main frame including a main circuit board; a driving frame installed so as to move on the main frame in at least one direction; a camera device including a sub-circuit board, the camera device being mounted on the driving frame; and a circuit connection for electrically connecting the main circuit board to the sub-circuit board, wherein the circuit connection includes both of its ends coupled to the main circuit board and the sub-circuit board, respectively, and a plurality of lead wires constructed so as to be moved separately with respect to the main circuit board and the sub-circuit board.

Abstract: An optical image stabilizer includes a main frame, a driving frame that moves in at least one direction within the main frame, a camera device is mounted on the driving frame, a pair of driving permanent magnets mounted on one of the main frame and the driving frame, a pair of coils mounted on the other of the main frame and the driving frame and faces the pair of driving permanent magnets, and at least one slidable bearing interposed between an inner sidewall of the main frame and an outer sidewall of the driving frame.

Abstract: The present invention provides a method of winding an armature coil on a cylindrical resin insulator of coreless motors while improving magnetic flux efficiency of the coil. This method allows a resulting motor to effectively generate desired torque by an application of a low current, thus conserving electricity. This method also simplifies the production process of the coreless motors, thus reducing the production cost of the motor and improving productivity and economical efficiency of the motors. In order to wind an armature coil on an insulator, the coil is repeatedly wound on the insulator, with each turn of the coil linearly extending on the upper surface, vertically extending down on the sidewall and linearly extending on the lower surface prior to vertically extending up on the sidewall of the insulator.
