Abstract:
1. A collapsible lens barrel comprising: a first holding frame for holding a first lens group; a second holding frame for holding a second lens group that is disposed on an image plane side with respect to the first lens group; an image blurring correction device for holding a third lens group for correcting an image blurring that is disposed on an image plane side with respect to the second lens group; a first actuator for moving the first holding frame toward the object plane side at the time of capturing an image and toward the image plane side at a time of non-capturing an image; a second actuator for moving the second holding frame in the optical axis direction; and at least two rod-like guide members each having an end fixed to the first holding frame; wherein the second holding frame is supported to be slidable with respect to the image blurring correcting device in the optical axis direction by the at least two rod-like guide members; and wherein the at least two rod-like guide members are slidable with respect to the second holding frame and the image blurring correcting device in the optical axis direction upon movement of the first holding frame.
