Document Type and Number:
Japanese Patent JP6509070
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an image blur correction device capable of being miniaturized and reduced in cost.SOLUTION: An image blur correction device 3 comprises: a correction lens 4; a movable member 22 holding the correction lens 4 and movably supported in a plane orthogonal to an optical axis direction; and oscillatory wave motors 101a-101c for driving the movable member 22. The oscillatory wave motors 101a-101c include: driving force extracting parts 114a-114c for outputting driving forces to the outside; and a guide part 116 for guiding a driving direction of the driving force extracting parts 114a-114c. The movable part 22 includes engagement parts 24a-24c engaging with the driving force extracting parts 114a-114c. When the movable member 22 is rotated in a plane by driving the oscillatory wave motors 101a-101b in an identical direction, the driving force extracting parts 114a-114c come into contact with the guide part 116 and the engagement parts 24a-24c to restrict translational movement of the movable member 22 in a plane.SELECTED DRAWING: Figure 4
