Abstract

An image blur correction device includes: a movable frame which is equipped with a lens or an imaging element and has a guide part; a fixed frame having a guide supporting part which movably supports the movable frame by coming into contact with the guide part; and a drive mechanism which drives the movable frame for correcting image blur by moving the movable frame relative to the fixed frame. The fixed frame has magnetic bodies, and the movable frame has urging magnets at positions corresponding to the magnetic bodies. Specifically, the urging magnets use attractive force between the magnets and the magnetic bodies, so as to urge the movable frame in a direction in which the guide part and the guide supporting part come into contact with each other.

Description

[0001] priority [0002] This application is based on and claims priority from each of Japanese Patent Application Nos. 2006-226290 filed on August 23, 2006 and 2006-226291 filed on August 23, 2006, and the entire contents thereof are hereby incorporated by reference Come in. technical field [0003] The present invention relates to an image blur correction device that corrects image blur when an image of an object is captured by allowing the image of the object to be imaged on an imaging element that generates image data to form an image of the object, and also relates to an imaging device . More particularly, the present invention relates to an image blur correction device having an image blur correction function capable of capturing a blur-corrected object image by allowing an imaging element to follow movement of the object image due to camera shake, and also relates to a device provided with the An imaging device of an image blur correction device.
