Embodiment Construction

[0027] (the whole frame)

[0028] Embodiments of the optical unit 1 with a shake correction function to which the present invention is applied will be described below with reference to the drawings. In this specification, the three axes of XYZ are orthogonal directions. One side of the X-axis direction is represented by +X, the other side is represented by -X, one side of the Y-axis direction is represented by +Y, and the other side is represented by +Y. One side is represented by -Y, one side in the Z-axis direction is represented by +Z, and the other side is represented by -Z. The Z-axis direction is a direction along the optical axis L of the optical module 2 mounted on the movable body 10 in a state where the movable body 10 of the optical unit with shake correction function 1 does not swing. In addition, the −Z direction is the image side in the optical axis L direction, and the +Z direction is the object side (subject side) in the optical axis L direction.

Abstract

An optical unit with a shake correction function that supports a movable body using a support mechanism of a movable frame, thereby reducing the amount of movement of the movable body due to external impact. An optical unit with a shake correction function according to the present invention includes a movable body (10) holding an optical module by a holder, and a gimbal mechanism (30) for swingably supporting the movable body relative to a fixed body (20). The gimbal mechanism includes a movable frame as a gimbal spring. The movable frame includes a fulcrum portion (61) and a connection portion (62), and the connection portion includes a meander portion (63). The cross-sectional shape of the meandering portion is a shape in which the direction perpendicular to the first axis (R1) and the second axis (R2) is defined as the first direction (Q1), and the first direction is perpendicular to the first direction and the direction perpendicular to the meandering portion is When the direction perpendicular to the meandering path (S) is taken as the second direction (Q2), the thickness (t2) of each leaf spring in the leaf spring constituting the movable frame in the second direction is greater than the thickness in the first direction (t0) thick.

Description

technical field [0001] The present invention relates to an optical unit with a shake correction function in which a movable body is supported in a swingable manner by a gimbal mechanism. Background technique [0002] Conventionally, various optical units equipped with an optical module for imaging have been used. This optical unit includes a shake correction drive mechanism that corrects shake by swinging the optical module in order to suppress disturbance of captured images due to hand shake and vibration. Furthermore, this optical unit includes a gimbal mechanism disposed between the movable body and the fixed body as a support mechanism for swingably supporting the movable body on which the optical module is mounted relative to the fixed body. Patent Document 1 discloses an optical unit with a shake correction function including such a gimbal mechanism. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2015-64501 [0004] The gimbal mechanism of Patent Document...
