Abstract
Provided is an image blur correction apparatus including a lens unit configured to include at least one lens and configured to be turnable in two different directions using, as supporting points, two axes that are orthogonal to an outer housing, a fixed member configured to turnably support the lens unit in the two directions, a first drive motor configured to be mounted on the fixed member and configured to turn the lens unit in one of the two directions, a second drive motor configured to be mounted on the fixed member and configured to turn the lens unit in another of the two directions, and a coupling member configured to be coupled to the first drive motor and the second drive motor and configured to include a coupling portion.
Claims12
An image blur correction apparatus comprising:
- a lens unit configured to include at least one lens, and configured to be turnable in a first direction which is a direction about a first supporting axis that is orthogonal to a light axis of the lens with respect to an outer housing, and in a second direction which is a direction about a second supporting axis that is orthogonal to the light axis and the first supporting axis;
- a fixed member configured to turnably support the lens unit in the first direction and the second direction;
- a first drive motor configured to be mounted on the fixed member and configured to turn the lens unit in the first direction;
- a second drive motor configured to be mounted on the fixed member and configured to turn the lens unit in the second direction;
- and
- a coupling member configured to be coupled to the first drive motor by a first movement member and the second drive motor by a second movement member and configured to include a coupling portion, the coupling portion being coupled to the lens unit to transmit drive force of the first drive motor and the second drive motor to the lens unit in a manner that the coupling member is moved along with turning of the lens unit,
- wherein the coupling member has, formed thereon,
- a first tolerance portion configured to maintain a coupled state of the first drive motor while the second drive motor is driven to allow the lens unit to turn in the second direction through movement of the first movement member, and
- a second tolerance portion configured to maintain a coupled state of the second drive motor while the first drive motor is driven to allow the lens unit to turn in the first direction through movement of the second movement member.
An imaging apparatus comprising:
- an image blur correction apparatus configured to include a lens unit that includes at least one lens and an outer housing that has the lens unit arranged therein, wherein
- the lens unit is configured to be turnable in a first direction which is a direction about a first supporting axis that is orthogonal to a light axis of the lens with respect to an outer housing, and in a second direction which is a direction about a second supporting axis that is orthogonal to the light axis and the first supporting axis to correct image blur, and
- wherein the image blur correction apparatus includes:
- a fixed member configured to turnably support the lens unit in the first direction and the second direction, and
- a coupling member configured to be coupled to the first drive motor by a first movement member and the second drive motor by a second movement member and configured to include a coupling portion, the coupling portion being coupled to the lens unit to transmit drive force of the first drive motor and the second drive motor to the lens unit in a manner that the coupling member is moved along with turning of the lens unit, wherein the coupling member has, formed thereon:
- first tolerance portion configured to maintain a coupled state of the first drive motor while the second drive motor is driven to allow the lens unit to turn in the second direction through movement of the first movement member, and
- a second tolerance portion configured to maintain a coupled state of the second drive motor while the first drive motor is driven to allow the lens unit to turn in the first direction through movement of the second movement member.
