Abstract
In a disk player, an optical pickup unit which is supported by guide shafts installed on a base records/reproduces information by emitting an optical beam onto a disk while moving along the guide shafts. A lead screw which is rotated by a transfer motor transfers a driving force to move the optical pickup unit. A tilt of the optical pickup unit is adjusted by an adjustment portion which moves up and down first ends of the guide shafts. A power transfer portion has a threaded portion which is to be coupled to the lead screw and installed at the optical pickup unit to be capable of relatively rotating with respect to the optical pickup unit. As the optical pickup unit moves up or down, the power transfer portion and the optical pickup unit rotate relative to each other so that the gear engagement state between the threaded portion and the lead screw can be maintained.
