Abstract

An image shake correction apparatus includes: a fixed member; a first guide shaft; a second guide shaft; an intermediate member; and a movable member.

Description

technical field [0001] The present invention relates to the technical field of image shake correction devices and image pickup devices. More specifically, the present invention relates to realizing the prevention of the movement of the movable member when the image shake is corrected in an image shake correcting device and an image pickup device including a first guide shaft and a second guide shaft extending perpendicularly to each other. The technical field that eliminates unnecessary rotational movement in the plane of the axial direction and ensures smooth moving operation of movable parts. Background technique [0002] Image pickup devices such as video cameras, still cameras, etc. include image shake correction means that move a lens or image pickup element in a direction perpendicular to the optical axis of the lens or image pickup element to perform image shake correction. [0003] One of such image shake correction devices is disclosed in Japanese Laid-Open Patent ...
