<P>PROBLEM TO BE SOLVED: To adjust an erecting mirror by using an autocollimator even in an optical pickup device of a finite optical system. <P>SOLUTION: This is an adjusting method of the erecting mirror 2 of the optical pickup device 4 which is provided with a light source 1 and an erecting mirror 2 for changing the direction of the light emitted from the light source, and which is made up of the finite optical system 3. The erecting mirror 2 is adjusted by using an adjusting tool 5 for the erecting mirror 2, a collimator lens 6, and an autocollimator 7; attaching the optical pickup device 4 to the adjusting tool 5; attaching the collimator lens 6 to the adjusting tool 5 so that the exit light from the collimator lens 6 becomes parallel light when the erecting mirror 2 is adjusted to a predetermined position; and using the autocollimator 7 so that the exit light from the collimator lens 6 becomes parallel. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
