Abstract
An image shake correction device includes: a base member; a lens frame that holds an image shake correction lens, and is mounted on the base member so as to be movable in a first direction and a second direction perpendicular to the first direction within a plane perpendicular to an optical axis of the image shake correction lens; a plurality of expandable and contractible mooring members that moors the lens frame to the base member such that the lens frame is able to move in the first direction and the second direction; a bracket that is supported by the base member so as to be swingable around a first axis parallel to the first direction; and a driving unit that drives the lens frame in the first direction and the second direction, as defined herein.
Claims18
An image shake correction device comprising:
- a base member;
- a lens frame that holds an image shake correction lens, and is mounted on the base member so as to be movable in a first direction and a second direction perpendicular to the first direction within a plane perpendicular to an optical axis of the image shake correction lens;
- a plurality of expandable and contractible mooring members that moors the lens frame to the base member such that the lens frame is able to move in the first direction and the second direction;
- a bracket that is supported by the base member so as to be swingable around a first axis parallel to the first direction;
- a driving unit that drives the lens frame in the first direction and the second direction;
- and
- a cover that interposes the lens frame between the cover and the base member,
- wherein the bracket has a guide portion arranged on a second axis parallel to the first direction,
- the lens frame has an engagement portion which engages with the guide portion so as to be movable along the second axis, to be relatively rotatable around the second axis, and to be detachably attached in an optical axis direction,
- the guide portion and the engagement portion are arranged on a side opposite to the driving unit while interposing a second straight line which is perpendicular to a first straight line passing through the optical axis and a center of the guide portion on the second axis and passes through the optical axis, when viewed in the optical axis direction,
- a side at which the driving unit is arranged is covered by the cover, whereas a side at which the guide portion and the engagement portion are arranged is opened, while interposing the second straight line, and
- a first mooring member that is formed so as to be adjacent to the guide portion and the engagement portion and a second mooring member that is arranged on a third straight line passing through the first mooring member and the optical axis and is arranged on a side opposite to the first mooring member with the second straight line interposed therebetween when viewed in the optical axis direction are included as the plurality of mooring members.
