Optical Unit with Shake Correction Function

摘要

Provided is an optical unit with a shake correction function, said optical unit being capable of ensuring a space wherein a drive mechanism and the like are positioned between a side surface of an optical module and a side surface of a stationary body, even when the optical module is supported by a gimbal mechanism in such a manner as to be able to swing with respect to the stationary body. In the optical unit, a gimbal mechanism is disposed by utilizing corners of an optical module and corners of a square tube-shaped body section of a stationary body. In other words, the optical unit is configured in such a manner that: a rectangular movable frame is positioned between a rectangular second frame of the optical module and a rectangular frame secured to the square tube-shaped body section); and a first corner and a third corner of the movable frame are swingably supported by corners of the rectangular frame. The optical unit is further configured in such a manner that a second corner and a fourth corner of the moveable frame swingably support corners of the second frame.

主权项

1. An optical unit with a shake correction function comprising:
an optical module; a fixed body having a body part which surrounds the optical module; a gimbal mechanism structured to swingably support the optical module around a first axial line intersecting an optical axis direction and swingably support the optical module around a second axial line intersecting the optical axis direction and the first axial line; and a shake correction drive mechanism structured to drive the optical module around the first axial line and the second axial line; wherein the gimbal mechanism comprises a rectangular movable frame comprising a first corner part, a second corner part adjacent to the first corner part, a third corner part separated in a direction of the first axial line from the first corner part, and a fourth corner part separated in a direction of the second axial line from the second corner part around an optical axis; and wherein the first corner part and the third corner part of the movable frame are swingably supported by the fixed body, and the second corner part and the fourth corner part of the movable frame swingably support the optical module.
