<p>PROBLEM TO BE SOLVED: To enable a smooth collapsing operation of a movable lens holding frame in an imaging device including a lens barrel having an optical type shake correction mechanism of a VCM system.SOLUTION: An imaging device 1 having a collapsible lens barrel 10 includes: an optical type shake correction mechanism of a voice coil motor (VCM) system that moves a movable frame 13B for holding lenses in a plane vertical to an optical axis by electromagnetic force of a magnet 32 and a coil 33; a first barrel 13 arranged with the optical type shake correction mechanism; and a second barrel 17 having a guide groove 17b inserting the first barrel within and parallel to the optical axis. When the movable frame 13 constituting the optical type shake correction mechanism is formed with a collapsing guide convex part 13Bd which is engaged with the guide groove, a power source is turned off and a movable part of the optical type shake correction mechanism performs a collapse in a free state, a collapse guide convex part is engaged with the guide groove, and the second barrel and the movable frame integrally move to a collapse completion position of a main body in a state in which the guide grove engages with the collapse guide concave part and positioning of the second barrel and the movable frame is performed.</p> |
