    摘要： A step motor includes a plurality of stator cores. Each of the stator cores have a coil unit coiled therearound. The step motor includes a rotor that includes a rotation shaft and a plurality of permanent magnets and is configured to rotate by magnetic interaction between the stator cores and the permanent magnets. The step motor also includes a plurality of conducting parts on one cross-sectional surface of the rotor. The step motor further includes a printed circuit board (PCB) including electric elements that are arranged at certain positions and are disposed to face the conducting parts. The conducting parts and the electric elements are configured to electrically or magnetically interact as the rotor rotates to change electrical signals generated by the electric elements.

    摘要： An autofocus driving unit for moving a lens holder supporting at least one lens in an optical axis direction with respect to an image sensor. The autofocus driving unit includes: a lead screw that has a length in a direction parallel to an optical axis and rotates to move the lens holder in the optical axis direction; a first driving source that rotates the lead screw so that the lead screw moves in multiple integers of a first distance in the optical axis direction and that comprises a rotor mounted in an outer circumference of the lead screw and a stator that is spaced apart from the rotor and rotates the rotor; and a second driving source that moves the lead screw and the rotor in a first direction that is parallel to the optical axis with respect to the stator so that the lens holder is moved by a second distance that is different from the first distance in the optical axis direction.
