Abstract:
1. A shake correction device, comprising a plurality of rectangle board-shaped permanent magnets, when a direction toward a photographed object is set as a positive direction of an optical axis, a surface of each of the permanent magnets faces a lens and the permanent magnets are disposed around the optical axis at an interval of 90 degrees, and the permanent magnets and the lens are swung along a direction perpendicular to the optical axis, wherein the shake correction device further includes: a brake member, formed by a non-magnetic conductor, and at least one eddy current induction plate arranged on the brake member, wherein, the at least one eddy current induction plate is arranged to be opposite to and has a gap with a surface on an outer periphery side of the permanent magnets, a surface on the positive direction of the optical axis, and a surface adjacent to the surface on the outer periphery side and the surface on the positive direction of the optical axis, and the at least one eddy current induction plate generates eddy currents in response to a magnetic field caused by the shift of the permanent magnets.
