Abstract

An optical element supporting device is provided that includes a fixed-side member, a first driving shaft, an intermediate member, a second driving shaft, a movable member and a driving mechanism. The first driving shaft extends in a first axis direction and is supported by the fixed-side member and the intermediate member is supported by the first driving shaft and rotates around the first axis with respect to the fixed-side member. The second driving shaft extends in a second axis direction orthogonal to the first axis direction and is supported by the intermediate member. The movable member is supported by the second driving shaft to rotate around the second axis with respect to the intermediate member and has a placing portion for placing an optical element. The driving mechanism applies a rotation force to the optical element that is placed on the movable member.

Dependent claims

An optical element driving device comprising:

in a rectangular coordinate system having a first axis, a second axis and a third axis that are orthogonal to each other,
a fixed-side member;
a first driving shaft which extends in the first axis direction and is supported by the fixed-side member;
an intermediate member which is supported by the first driving shaft and rotates around the first axis with respect to the fixed-side member;
a second driving shaft which extends in the second axis direction and is supported by the intermediate member;
a movable member which is supported by the second driving shaft, rotates around the second axis with respect to the intermediate member, and has a placing portion for placing an optical element;
and
a driving mechanism applying a rotation force to the optical element that is placed on the movable member,
wherein a portion of the driving mechanism is attached to the movable member on a side opposite to the placing portion with the first driving shaft and the second driving shaft sandwiched therebetween in the third axis direction.
