ピツクアツプの受光素子調整装置。 An optical type in which an objective lens facing the recording surface is provided on a slide base that moves along the recording surface of the disk, and a light emitting element and a light receiving element are connected to this objective lens via an optical system. In the pickup, a positioning hole formed along the optical axis is bored in the side surface of the slide base, and a positioning protrusion formed on the adjustment spacer is inserted into the positioning hole so as to be freely advanced and retracted. At the same time, the adjustment spacer and the slide base are screwed together through an elongated hole extending in the optical axis direction, and a substrate with a light receiving element is mounted on the mounting surface of the adjustment spacer in a direction crossing the optical axis. An optical pick-up light-receiving element adjustment device characterized by being adjustable.
