Optical Unit with Shake Correction

Abstract

To provide a method for effectively bringing the center of gravity position of the movable module in the direction of the optical axis close to the supporting position of the movable module even when the movable module is supported so as to be swingable at an intermediate position in the direction of the optical axis of the movable module. Optical unit with shake correction function. In the optical unit (100), the gimbal mechanism (30) (support mechanism) supports the movable module (10) in a swingable manner at an intermediate position in the Z-axis direction of the movable module (10). The movable module (10) has an optical module (1) holding a lens (1a) and a weight (5) attached to the front end (1c) of the optical module (1) in the direction of the optical axis L. Therefore, the position of the center of gravity of the movable module (10) can be displaced toward the support position of the gimbal (30) relative to the position of the center of gravity of the optical module (1) in the direction of the optical axis L. The front end surface (51a) of the counterweight (5) in the direction of the optical axis L is constituted by a plane perpendicular to the direction of the optical axis L.

Description

technical field [0001] The present invention relates to an optical unit with a shake correction function installed in a mobile phone with a camera or the like. Background technique [0002] In recent years, mobile phones have been configured as optical devices equipped with an optical unit for photographing. In this optical unit, in order to suppress disturbance of a captured image due to user's hand shake, a configuration is proposed in which the shake is corrected by swinging the optical module. In order to perform such shake correction, it is necessary to support the optical module so as to be able to swing relative to the fixed body. [0003] Therefore, a structure has been proposed in which the optical module is supported swingably by a pivot provided on the rear side of the optical axis direction of the optical module, and the optical module is swung around the pivot to correct the shake of the optical unit (see Patent Document 1, 2). [0004] However, in the case o...

Problems solved by technology

Therefore, it is necessary to arrange enough space in the direction perpendicular to the optical axis direction around the optical module, so there is a problem that the dimension of the optical unit in the direction perpendicular to the optical axis direction becomes large.
