Abstract

The invention discloses an image stabilizer, a lens barrel and an imaging device. The stabilizer stabilizes an image by moving a correction lens for stabilizing an image formed by a lens system in first and second directions perpendicular to the optical axis of the lens system and perpendicular to each other, including on one side of the correction lens an actuator, and the actuator moves the correction lens in a first direction and a second direction. The driver has a first coil generating a thrust for moving the correction lens in the first direction, a second coil for generating a thrust for moving the correction lens in a second direction, applying a magnetic force to the first The magnets of the first coil and the second coil, and the yoke supporting the magnets, and the thrust generating portion of the first coil and the thrust generating portion of the second coil are made to cross and overlap each other at right angles, and the magnetic force of the magnets is applied to the common overlapping portion of the two thrust producing sections.

Description

[0001] The present invention includes JP 2005-167307 submitted to the Japan Patent Office on June 6, 2005, JP 2005-178358 submitted to the Japan Patent Office on June 17, 2005, and JP 2005-319786 submitted to the Japan Patent Office on September 2, 2005 Japanese Patent Application for related subject matter, the entire contents of which are incorporated herein by reference. technical field [0002] The present invention relates to an image stabilizer for stabilizing image blurring caused by vibration or the like at the time of shooting; a lens barrel having the image stabilizer; and an imaging device, such as a digital still camera or a video camera, including the lens barrel. Background technique [0003] In recent years, the performance of imaging devices such as digital still cameras and video cameras has been significantly improved, making it possible for anyone to easily shoot still images and moving images with high image quality at high efficiency. The improvement in ...
