<P>PROBLEM TO BE SOLVED: To provide a mechanism for miniaturizing a lens barrel by increasing the efficiency of the space of a base plate where the drive parts of a plurality of light quantity adjustment members are arranged, on the outer circumferential side of a correction lens. <P>SOLUTION: The lens barrel includes a base plate 4 in which drive parts 3, 5, and 6 of the plurality of light quantity adjustment members are arranged, a holding member 2 provided on the base plate 4, to be movable in a direction orthogonal to an optical axis and holding a correction lens 1 correcting an image blur, and a correction lens drive part including oblong coils 7a and 7b provided on the base plate 4 in such a state that the oblong coils 7a and 7b are away from each other in a circumferential direction and magnets 2a and 2b provided in positions facing the coils 7a and 7b in an optical axial direction on the outer circumferential side of the correction lens 1 of the holding member 2 and moving the holding member 2 with respect to the base plate 4 in the direction orthogonal to the optical axis. The coils 7a and 7b are arranged so that a line X extending in the long axis direction of one coil 7a and a line Y extending in the long axis direction of the other coil 7b cross each other on the surface of the base plate 4 on the outer circumferential side of the correction lens 1 and one drive part 5 of the drive parts 3, 5, and 6 of the plurality of light quantity adjustment members is arranged on the surface where the line X and the line Y cross each other. <P>COPYRIGHT: (C)2013,JPO&INPIT |
