Claims

[Scope of claim for utility model registration] During disk loading, the disk is lowered onto a turntable attached to the output rotating shaft of the main motor, and when the disk is taken out,
In a disk lifting device that raises a disk above the turntable, from a substantially ring-shaped disk abutting section, a ring section parallel to the disk abutting section, and a support section connecting the disk abutting section and the ring section. an elevator that is arranged around the outer periphery of the main motor so as to be able to slide in the direction of the output rotation axis of the main motor; a coil spring that is in contact with the back surface of the disk mounting surface of the elevator, the other end of which is in contact with the ring portion of the elevator that is slidable; It comes into contact with the bottom of the ring part,
The elevator is raised against the spring force of the coil spring, and when the elevator is lowered, the elevator contact portion contacts the bottom surface of the ring portion of the elevator and is biased by the spring force of the coil spring. and a lifter arm that limits the descending speed of the elevator as it moves downward, and when the elevator ascends and descends, a plurality of elevator contact surfaces provided on the elevator contact section limit the rotation of the elevator contact section. The disk lifting device is configured such that the bottom surface of the ring portion sequentially contacts the bottom surface of the ring portion as the disk moves, so that the bottom surface of the ring portion always contacts the elevator contact portion at a substantially constant position.
