Abstract

An optical pickup has a base having a screw hole, a holder attached to the base, a laser diode held by the holder, a leaf spring, and an adjusting screw. The holder is formed of a substantially rectangular metal plate having short and long sides and is formed with a laser hole for fitting the laser diode through a center thereof. An angular fulcrum is formed at the center of a back surface of the holder along a direction parallel to the short side. The fulcrum is brought into abutment with the base via the leaf spring and one end of the holder is urged toward the base by the leaf spring. The holder is temporarily secured to the base by screwing the adjusting screw through an insertion hole formed at the other end of the holder into the screw hole of the base.
