Title:
LENS MOVING MECHANISM
Document Type and Number:
WIPO Patent Application WO/2018/079663
Kind Code:
A1
Abstract:
This lens moving mechanism is equipped with a first lens guiding unit that guides a lens mount to which a lens for projecting light is mounted in two orthogonal axis directions from among three orthogonal axis directions that include the optical axis direction of the light. The first lens guiding unit is equipped with a first track rail and a second track rail disposed intersecting along the two orthogonal axis directions, and one or a plurality of slider blocks mounted to both or either of the first track rail and the second track rail in a manner enabling relative movement therebetween. The one or plurality of slider blocks are disposed on an intersecting portion of the first track rail and the second track rail in one axis direction perpendicular to the two orthogonal axis directions, or are disposed such that at least a portion of each overlap in the one axis direction.
