Pick-up angle adjustment mechanism for optical disk apparatus

A pick-up angle adjustment apparatus in provided for adjusting an angle of an optical pick-up mounted in an optical disk apparatus. In the pick-up angle adjustment apparatus, a first guide shaft (6) has a first length (L1) between a pair of ends thereof for guiding and supporting the optical pick-up. A second guide shaft (7) has a second length (L2) between a pair of ends thereof for guiding and supporting the optical pick-up. A first adjustment member (9) is operable for vertically moving one end of the first guide shaft so as to adjust the angle of the optical pick-up. The first adjustment member is capable of moving the one end of the first guide shaft by a first distance when the first adjustment member is operated by a given operation amount. A second adjustment member (11) is operable for vertically moving one end of the second guide shaft so as to adjust the angle of the optical pick-up. The second adjustment member is capable of moving the one end of the second guide shaft by a second distance when the second adjustment member is operated by the same operation amount as applied to the first adjustment member. A distance ratio of the first distance and the second distance is set equal to a length ratio of the first length and the second length.
