IMAGE BLUR CORRECTION MECHANISM

摘要

PROBLEM TO BE SOLVED: To perform a stable correction control in the image blur correction of an optical apparatus. SOLUTION: An aperture 10A is provided roughly at the center of a fixed ring 10. A ring-shaped protrusion part 10B is formed to the rim of the aperture 10A at a side to which a lens supporting frame 20 is arranged in the fixed ring 10. The annular ring 101 of a frame reception mechanism 100 is fitted to the protrusion part 10B. A V-shaped groove whose cross-sectional shape is roughly V-shape is formed along with a circumference direction in the annular ring 101 and a plurality of steel balls 102 are arranged in the V-shaped groove over whole circumference. Each steel ball 102 is made to be in sliding contact with the lens supporting frame 20 and rotates according to the transfer of the lens supporting frame 20. A ring-shaped wave washer 103 is arranged between the annular ring 101 and the plane part of the fixed ring 10. The wave washer 103 exposes energizing force of a direction which is parallel with the optical axis OP and a direction which heads to the lens supporting frame 20 from the fixed ring 10 to the lens supporting frame 20 with the annular ring 101 and the balls 102.
