Abstract:
An image shake preventing mechanism, comprising:a driven member to be driven so as to prevent the image shake; a holding member for holding the driven member; a first parallel linkage member arranged perpendicular to an optical axis of the driven member, the first parallel linkage member having link parts arranged in a form of parallelogram and connected with each other by flexible parts so that the first parallel linkage member can be deformed into any other form of parallelogram in a plane perpendicular to the optical axis of the driven member, one of the link parts being fixed to the holding member; an intermediate member fixed to another of the link parts of the first parallel linkage member parallel to the one thereof; a second parallel linkage member overlapped with the first parallel linkage member in parallel relation thereto, the second parallel linkage member having link parts arranged in a form of parallelogram and connected with each other by flexible parts so that the second parallel linkage member can be deformed into any other form of parallelogram in a plane perpendicular to the optical axis of the driven member , one of the link parts being fixed to the intermediate member; and a base member fixed to another of the link parts of the second parallel linkage member parallel to the one thereof, wherein the one of the link parts of the first parallel linkage member is generally perpendicular to the one of the link parts of the second parallel linkage member.
