Claims

[Scope of utility model registration request]

A motor, a turntable rotationally driven by the motor, an elevating body that moves up and down along the circumferential surface of the motor and has a disk support portion that supports a disk, and a bearing mounted on the top surface located on the shaft side of the motor. The disk is rotatably supported by the bearing, and as the outer body moves downward, the disk placed on the disk support portion of the elevating body is rotated by the disk placed on the turntable. A pawl that engages around the center hole, and an end that is formed integrally with the pawl and contacts the elevating body to rotate the pawl in a direction opposite to the axis of the motor by the weight of the elevating body. A clamp claw in which the distance from the disk abutting part of the claw part to the shaft support is shorter than the distance from the lifting body contact part at the end to the shaft support, and this clamp claw is constantly rotated in the direction of the motor shaft. A recording disk reproducing device equipped with a biasing means for applying a force to the recording disk.
