Abstract

An imaging optical device configured such that shaking can be appropriately corrected by smoothly rocking a lens drive device on which a lens and an imaging element are mounted. An imaging optical device (1) comprises: a movable module (12) having a lens drive device (2) on which a lens and an imaging element are mounted; a support body (5) for supporting the movable module (12); a rocking drive mechanism for rocking the movable module (12); and a plate spring (17) for rockably supporting the movable module (12). The plate spring (17) is provided with a holding section (17a) for holding the movable module (12), a fixed section (17b) fixed to the support body (5), and a spring section (17c) for connecting the holding section (17a) and the fixed section (17b) to each other. The spring section (17c) can deform in the direction perpendicular to the optical axis (L) and in the direction of the optical axis.

Description

technical field [0001] The present invention relates to a photographic optical device having a shake correction function capable of swinging a lens driving device equipped with a lens and an imaging element to correct shake. Background technique [0002] In recent years, mobile devices such as mobile phones have been equipped with optical devices for photographing. In the case of using a mobile device, hand shake is prone to occur when taking pictures. Therefore, an optical device capable of correcting hand shake during photography has been proposed (for example, refer to Patent Document 1). [0003] The optical device described in this patent document 1 includes: a movable part equipped with a lens and an imaging element; a pivot fixed to the base of the optical device and contacting the bottom surface of the movable part; a leaf spring for swingably supporting the movable part; and a swing mechanism for swinging the movable part. In this optical device, the swing mechan...
