<P>PROBLEM TO BE SOLVED: To provide an optical head device capable of easily adjusting both the position and direction of a diffraction grating on an optical axis on a frame, and a method for manufacturing the optical head device. <P>SOLUTION: A holder mounting hole 36, a first eccentric pin insertion hole 37 and a second eccentric pin insertion hole 38 are formed in the frame 3 of the optical head device, and a first groove 41 extending in the direction of an axis and a second groove 42 extending in the direction perpendicular to the direction of the axis are formed on the outer circumferential surface of a diffraction grating holder 40 for holding the diffraction grating. If a first eccentric pin 61 is rotated while the eccentric pin 61 is inserted into the first groove 41 through the first eccentric pin insertion hole 37, the diffraction grating holder 40 or rotated around the axis, and if the second eccentric pin 62 is rotated while the eccentric pin 62 is inserted into the second groove 42 through the second eccentric pin insertion hole 38, the diffraction grating holder 40 is moved into the direction of the axis. <P>COPYRIGHT: (C)2003,JPO |
