Abstract

An image-capturing optical device which can stably correct hand-shake blur and is thin. An image-capturing optical device (1) comprises: a movable module (18) having a camera module (2) on which a lens and an image-capturing element are mounted; a support body (5) for supporting the movable module (18); and a hand-shake blur-correcting mechanism for correcting hand-shake blur by rocking the movable module (18) in such a manner that the optical axis (L) of the camera module (2) tilts relative to the support body (5). The movable module (18) is provided with a sensor (4) for detecting the tilt of the camera module (2) and also with a cover member (12) for forming the outer peripheral surface of the movable module (18). The sensor (4) is disposed on the inner side of a side surface section (12b) of the cover member (12).

Description

technical field [0001] The present invention relates to an optical device for photographing with a camera shake correction function, which corrects camera shake by swinging a camera unit mounted with a lens and an imaging element. Background technique [0002] In recent years, photographic optical devices have been installed in mobile devices such as mobile phones. And mobile devices are prone to camera shake when taking pictures. Therefore, an optical device capable of correcting camera shake during shooting has been proposed (for example, refer to Patent Document 1). [0003] The optical device described in this patent document 1 includes: a movable part loaded with a lens and an imaging element; a pivot fixed on the base of the optical device and abutting against the bottom surface of the movable part; a leaf spring for supporting the movable part so as to be able to swing; and a swing mechanism for swinging the movable part. In this optical device, the swing mechanism...
