PROBLEM TO BE SOLVED: To provide a deflection correcting device capable of solving a problem of interference with an image-pickup optical system, even when the deflection correcting device is applied to a hand shake correcting device using an optical axis angle variable mechanism using afocal optical system as an optical axis angle variable mechanism. SOLUTION: A piano-concave lens 211(P) and a piano-convex lens 211(Y) constitute an afocal optical system, and a rotational axis 212(P) pivots the piano-concave lens 211(P) so that it freely rotates in a plane vertical to the optical axis, while a rotational axis 212(Y) pivots the piano-convex lens 211(Y) so that it freely rotates in a plane vertical to the optical axis. Deflection detectors 214(P), 214(Y), an arithmetical operation part 220, driving circuits 230(P), 230(Y), and driving motors 213(P), 213(Y) drive to rotate the lens 211(P), 211(Y) for a hand shake correction. |
