Abstract

An image blur correction device includes a lens unit having at least one lens and rotationally moving in a first direction which is a rotation direction of a first fulcrum axis and in a second direction which is a rotation direction of a second fulcrum axis relative to an outer casing, a first driving motor which causes the lens unit to pivot in the first direction, and a second driving motor which causes the lens unit to pivot in the second direction. An auxiliary axis is disposed opposite to the first driving motor with interposing of the lens unit, the lens unit pivots in the first direction and in the second direction by the rotation of output axes of the first and second driving motors, and each output axis is rotatably supported by a pair of first bearings and each auxiliary axis is rotatably supported by a second bearing.

First claim

What is claimed is:

1. An image blur correction device, comprising:
a lens unit which has at least one lens which pivots in a first direction around a first fulcrum axis, orthogonal to an optical axis of the lens and which pivots in a second direction around a second fulcrum axis, orthogonal to the optical axis and the first fulcrum axis;
a first driving motor which causes the lens unit to pivot in the first direction; and
a second driving motor which causes the lens unit to p…
