Claims

[Scope of utility model registration request]

Two rectangular lenses forming a long rectangle or R-shaped rectangle in the left and right horizontal directions when viewed from the optical axis direction, with the short sides in the horizontal direction being the short sides, and the long sides being the top and bottom surfaces in the vertical direction. Transverse to the optical axis so that the outer surface of each lens in the optical axis direction at or near the short sides on both sides of the two rectangular lenses comes into contact with the lens holder that fixedly supports the lenses. and one side of the optical axis in the direction transverse to the optical axis so as to be in contact with the lateral side surface of each of the short sides of the two rectangular lenses on one side. and a horizontal stopper provided only on one side in the vertical direction with respect to the optical axis so as to contact the bottom surface in the vertical direction of each of the long sides of the two rectangular lenses. first and second lens holders are interposed between the lenses near the short sides on both sides of the two rectangular lenses, the first lens holder is
A biasing force is applied to each lens to bring the outer surface of each lens at or near the short side of the two rectangular lenses into contact with each other in the optical axis direction, and the second lens presser is applied to each lens. Similarly to the first lens holder, each of the two rectangular lenses applies a biasing force that causes the outer surfaces of the lenses at or near the short sides to come into contact with each other in the optical axis direction. At the same time, a biasing force is applied to each lens so as to bring the lateral side surfaces of each of the two rectangular lenses into contact with each other in the lateral direction. The long sides of the two rectangular lenses are pressed against the top surface in the vertical direction of each lens, so that the bottom surfaces of the two rectangular lenses in the vertical direction are brought into contact with each other in the vertical direction. Fixed support mechanism for rectangular lenses.
