Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a lens for an optical reader which enables skew adjustment by a method which is different from the conventional method and in a shorter time, with higher degree of accuracy. SOLUTION: The lens 10 for an optical reader has two curved surfaces (spherical surfaces) 11, 12 and a flange part 13 formed around the curved surfaces. A small plane 14 which perpendicularly intersects the axis of the lens has been formed in the center of the curved surface 11.
