ABSTRACT:
A structure for positioning a plurality of noncircular lenses relative to a lens holding frame which holds the noncircular lenses precisely. The structure includes a first lens frame which holds a first noncircular lens, and a second lens frame which holds a second noncircular lens. A first coupling part of the first lens frame has a first connecting surface which is perpendicular to a centering axis of the first noncircular lens, and a second coupling part of the second lens frame has a second connecting surface, contacting with the first connecting surface, which is perpendicular to the centering axis of the first noncircular lens. When the first coupling part is connected to the second coupling part, they are prevented from rotating relative to each other around the centering axis which is perpendicular to both the first and second connecting surfaces, by a mechanism which prevents a mutual rotation between the first coupling part and the second coupling part of the lens frame.
