PROBLEM TO BE SOLVED: To provide a structure of mounting a lens with which deviation of an optical axis is made small and precise mounting can be conducted. SOLUTION: The structure of mounting the lens is provided with a holding member 1 having a cylindrical section 2, an optical lens member 4 mounted in the front section within the cylindrical section 2 and an optical lens 7 mounted at the back section of the optical lens member 4 within the cylindrical section 2. Tip sections of projected sections 7b of the optical lens 7 are engaged with notched sections 6e provided on pulled out sections 6b of the optical lens member 4 so as to match the optical axes of the optical lens member 4 with the optical lens 7. Therefore, dispersion between the optical lens 7 and the optical lens member 4 is made small compared with a conventional case in which positioning is conducted for the optical lens member within the cylindrical section. Thus, an optical axis G deviation of the optical lens 7 and the optical lens member 4 is made small and precise lens mounting is achieved. COPYRIGHT: (C)2006,JPO&NCIPI
