特徴とする光ピツクアツプ装着基板。 In an optical pickup drive device comprising a worm gear mounted on a rotating shaft of a motor, a rotating body that meshes with the worm gear, and an optical pickup mounting board on which a rack gear that meshes with the rotating body is mounted, the rack gear is connected to the rack gear. The optical pickup mounting board is movably mounted on the optical pickup mounting board by a shaft and a long hole that is inclined with respect to the direction of movement of the optical pickup mounting board, and the rack gear is mounted in a direction in which the rack gear is pressed against the rotating body by the long hole and the shaft. The optical pickup mounting board is characterized in that a spring is provided for urging the rack gear in the moving direction of the optical pickup mounting board so that the optical pickup mounting board is biased.
