Abstract:
1. A image blur correcting mechanism for effecting image blur correction, comprising: a first guide shaft extending in a first direction which is a predetermined direction orthogonal to an optical axis direction of a lens group; a base frame supporting the first guide shaft; a first correcting moving frame supported by the base frame through the first guide shaft movably in the first direction; a second guide shaft extending in a second direction orthogonal to both of the optical axis direction and the first direction and supported by the first correcting moving frame; and a second correcting moving frame being supported by the first correcting moving frame through the second guide shaft movably in the second direction, while being movable in the first direction along movement of the first correcting moving frame with respect to the base frame in the first direction, wherein the image blur correction is performed by moving the first correcting moving frame in the first direction and moving the second correcting moving frame in the second direction, the base frame has a first limiting part and a second limiting part respectively configured to limit an amount of movements of the second correcting moving frame in the first direction and the second direction by contact made between the second correcting moving frame and the base frame; and the first limiting part and the second limiting part are provided within a single plane which is orthogonal to the optical axis direction.
