<P>PROBLEM TO BE SOLVED: To provide an optical pickup device in which a position and a tilt of a laser diode can be accurately and easily adjusted with respect to a light axis in a simple configuration. <P>SOLUTION: A laser diode 1 is pressed into an attachment hole 2a opened in the center of a holder 2 from the front. A convex portion 2b is protrusively arranged in the center of upper and lower ends of a back of the holder 2. A plate 3 is arranged in the back of the holder 2, and a cutout portion 3a is provided in the center of upper and lower ends of the plate 3. The convex portion 2b of the holder 2 is fitted in the cutout portion and pivoted in it, thereby the holder 2 becomes rotatable about the convex portion as a center. Furthermore, a cutout portion 3b is provided in the center of right and left ends of the plate 3, and also a convex portion 4a is protrusively arranged in the center of right and left ends of a front F of a base 4 situated in the back of the plate 3. The cutout portion 3b of the plate 3 is fitted to the convex portion 4a to work as a pivot, thereby the plate 3 becomes rotatable around the convex portion as a center. <P>COPYRIGHT: (C)2007,JPO&INPIT |
