An optical unit with shake-correction function is provided. A rotational support structure for supporting a movable body including a camera module around an optical axis is rotatably supported around a first axis and a second axis by a gimbal mechanism. The rotational support structure includes: a first annular groove, provided in the movable body; a plate roller, having a second annular groove facing the first annular groove in a direction of a Z axis; and a plurality of spherical objects, configured to be inserted into the first annular groove and the second annular groove, and roll between the movable body and the plate roller. The gimbal mechanism is configured to rotatably support the plate roller around the first axis.

The present application claims priority under 35 U.S.C. § 119 to Japanese Application No. 2020-036404, filed on Mar. 4, 2020, and the entire content of which is incorporated herein by reference.
The present invention relates to an optical unit with shake-correction function for correcting shake by rotating a camera module around an optical axis.
In an optical unit mounted on a mobile terminal or a mobile body, there is an optical unit that rotates a movable body provided with a camera module, along an optical axis, a first axis perpendicular to the optical axis, and a second axis orthogonal to the optical axis and the first axis, in order to suppress the disturbance of an image captured when the mobile terminal or the mobile body is moved. Japanese Unexamined Patent Publication No. 2015-82072 (Patent Document 1) and Japanese Unexamined Patent Publication No. 2019-200270 (Patent Document 2) describe such an optical unit with shake-correction function.
Embodiments will now be described, by way of example only, with reference to the accompanying drawings which are meant to be exemplary, not limiting, and wherein like elements are numbered alike in several figures, in which:
FIG. 1 is a perspective view of an optical unit with shake-correction function;
FIG. 2 is a plan view of the optical unit with shake-correction function when viewed from an object side;
Hereinafter, embodiments of an optical unit with shake-correction function to which at least an embodiment of the present invention is applied will be described with reference to the drawings.
Overall Configuration
FIG. 1 is a perspective view of an optical unit with shake-correction function. FIG. 2 is a plan view of the optical unit with shake-correction function when viewed from an object side. FIG. 3 is an exploded perspective view of the optical unit with shake-correction function. FIG. 4 is a perspective view of an optical unit main body. In FIG. 4, a base, a flexible printed board, a first magnetic plate, and a second magnetic plate are omitted. FIG. 5 is a plan view of the optical unit main body. In FIG. 5, the base and the flexible printed board are omitted. FIG. 6 is a cross-sectional view taken along the line A-A of FIG. 2. FIG. 7 is a cross-sectional view taken along the line B-B of FIG. 2.
