<P>PROBLEM TO BE SOLVED: To provide an optical pickup in which an attaching position and an attaching angle or the like of a grating can be adjusted and the attached state of the grating is maintained in spite of thin configuration of the optical pickup. <P>SOLUTION: The optical pickup 7 is made thin by vertically opening the space 20C of a base 20. Receiving parts K1 and K2 having grooves K1D and K2D are provided in a second holder 34. The pressing parts J1 and J2 of a pressing member 35 are respectively engaged with the receiving parts K1 and K2 of the second holder 34 to temporarily fix a first holder 33 incorporating the grating 22 and the second holder 34 and vertically position the holders. The horizontal position of the second holder 34 and the rotational angle of the first holder 33 are adjusted, and fixed by adhesives or the like. Thus, the entire pickup is made thin, and the attaching position and the attaching angle of the grating 22 are maintained in optimal states subjected to adjustment. <P>COPYRIGHT: (C)2011,JPO&INPIT |
