IMAGE BLUR CORRECTION APPARATUS, IMAGE PICKUP APPARATUS AND OPTICAL APPARATUS

摘要

An image blur correction apparatus includes a base plate member, a holding member that holds an image blur correction lens, an even number of actuator constituting members for moving the holding member, a support member arranged in such a manner that the holding member is movable relative to the base plate member, and a plurality of bias members performing biasing in such a manner that the support member is sandwiched by the base plate member and the holding member, wherein at least one of the bias members is arranged in a region between two of the actuator constituting members, and wherein the bias members arranged in two regions each between two of the actuator constituting members, the two regions opposing each other through a gravity center of the holding member.

1. An image blur correction apparatus comprising:
a base plate member; a holding member that holds an image blur correction lens; an even number of actuator constituting members mounted on the holding member for moving the holding member; a support member arranged to support the holding member in such a manner that the holding member is movable relative to the base plate member; and a plurality of bias members, one end and the other end thereof being respectively mounted on the holding member and the base plate member, the bias members performing biasing in such a manner that the support member is sandwiched by the base plate member and the holding member, wherein at least one of the bias members is arranged in a region between two of the actuator constituting members adjacent to each other in the circumferential direction of the holding member, and wherein the bias members arranged in two regions each between two of the actuator constituting members adjacent to each other in the circumferential direction are the same in number, the two regions opposing each other through a gravity center of the holding member.
