PROBLEM TO BE SOLVED: To easily adjust a division scanner and to make satisfactory the scanning line position, a beam diameter and a light quantity at the point part on a medium to be scanned. SOLUTION: A semiconductor laser beam source is moved to coarsely adjust the light quantity (100), so that the semiconductor laser beam source and a cylindrical mirror are adjusted to coarsely adjust a subscanning position(102). Thereafter, a beam focus position is adjusted (104), the beam diameter at the joint part is adjusted (106), main scanning and sub scanning positions at the joint part are adjusted (108), and the light quantity at the joint part is adjusted (110). |
