ABSTRACT:
The invention concerns a lens mounting structure which can reduce a displacement of the lens in the direction of mounting caused by the shrinkage of adhesive is reduced to enhance the lens mounting accuracy and to assure predetermined optical characteristics. The lens mounting structure in which an f.theta. lens (20) is supported by and adhered to a lens mount (22), includes support columns (30, 32), at the upper surface (30A) of which a protrusion (30B) is formed. The protrusion (30B) has a reference support point (30C) for supporting the f.theta. lens (20) on the mount (22). The f.theta. lens (20) comes into contact with this reference support point (30C), and a surface of the protrusion (30B), the upper surface (30A) of the support column (30) and a periphery of the f.theta. lens (20) surrounding a portion in which the f.theta. lens (20) comes into contact with the reference support point (30C), are adhered so as to mount the f.theta. lens (20).
