<P>PROBLEM TO BE SOLVED: To provide an actuator capable of stably supporting a movable part in parallel with a fixed part. <P>SOLUTION: The actuator (10) moving an image stabilizing lens includes: a fixed side member (12); a movable side member (14) to which the image stabilizing lens is attached; a movable side member supporting means (18) supporting the movable side member; at least three driving magnets (22) attached to the movable side member and arranged on the circumference of a circle centering on the optical axis of the image stabilizing lens; driving coils (20) attached to the fixed side member, to correspond to the driving magnets respectively; an attracting yoke (26) attached to the fixed side member and attracting the movable side member to the fixed side member by the magnetic force of the driving magnets; a position detecting means detecting the position of the movable side member; and a control means (36) controlling driving current flowing into each driving coil, based on the information of the detected position. <P>COPYRIGHT: (C)2007,JPO&INPIT |
