Abstract
Provided is an image blur correction apparatus including a lens unit that configured to include at least one lens, and configured to 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 unit configured to turn the lens unit in the first direction, and a second drive unit configured to turn the lens unit in the second direction.
Claims23
A blur correction apparatus comprising:
- a lens unit that configured to include at least one lens, and configured to 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 unit configured to turn the lens unit in the first direction;
- and
- a second drive unit configured to turn the lens unit in the second direction,
- wherein the lens unit is provided thereon with a first turning shaft that acts as a turning support in one of the first direction and the second direction, and whose center axis is in line with one of the first supporting axis and the second supporting axis,
- wherein the fixed member is provided thereon a second turning shaft that acts as a turning support in another of the first direction and the second direction, and whose center axis is in line with another of the first supporting axis and the second supporting axis,
- wherein a first support groove into which the second turning shaft is inserted, that acts as a bearing for the second turning shaft, and that extends in a light axis direction is formed on the lens unit, and
- wherein a second support groove into which the first turning shaft is inserted, that acts as a bearing for the first turning shaft, and that extends in the light axis direction is formed on the fixed member,
- wherein the first drive unit and the second drive unit are provided on an outer face side of the lens unit in a light axis direction,
- wherein a main body configured to include the lens and a support member configured to turnably support the main body in a direction about the light axis are provided on the lens unit,
- wherein the first turning shaft is provided on the support member, and the first support groove is formed in the support member, and
- wherein the main body is turnable in a direction about the light axis.
