<P>PROBLEM TO BE SOLVED: To provide an optical pickup device in which an optical path along which light emitted from a light source reaches an information recording medium can be changed easily without adjusting the position of the light source, freedom of change is large and deviation of the optical path is not caused even after the change and which has high reliability. <P>SOLUTION: A guiding part 12 which is constituted of four guide members 12a, 12b, 12c, 12d is formed on the bottom 6a of a housing 6 so that the members rise up outward from the bottom 6a. When a standing mirror holding stand 8 is inserted between the guide members 12a, 12c and between the guide members 12b, 12d and engaged with the members, the stand 8 is guided into the guiding part 12 and becomes slidable and moves in a direction which is roughly parallel with the optical axis of light 2a. As a result, the position of the reflection point of the light 2a on the reflecting surface of a standing mirror 7 held on the standing mirror holding stand 8 can be adjusted in the direction being roughly parallel with the optical axis of the light 2a and it is possible to adjust the optical path so that the light 2a reaches the best point of an information recording medium 10. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
