Claims (1)

[Scope of utility model registration request] an optical pickup device provided movably in a radial direction with respect to the chassis; a disk drive device having a disk mounting surface rotatably provided with respect to the chassis; and a support that resiliently supports the chassis. a device, a rotary opening/closing lid that closes and opens the upper part of the disk mounting surface;
a holding device comprising a pair of clamping members magnetically attracted to each other, which presses and holds an optical disc placed on the disk mounting surface against the disc mounting surface; and one of the clamping members of the holding device. a rotary arm that supports the rotary arm so as to be movable in a plane orthogonal to the central axis of the disk mounting surface and movable in the vertical direction with respect to the central axis of the disk mounting surface; a compression spring disposed between the rotary opening/closing lids; and an engaging portion disposed such that the rotation arm is not separated from the rotary opening/closing lid by a predetermined distance or more due to the compression spring; The arm is provided with a thrust receiver, and one of the clamping members has a thrust ball facing the thrust receiver and a core that aligns the center axis of the clamping member with the center of the disk mounting surface. A mating mechanism is provided, and when a disc is placed on the disc mounting surface and the rotary opening/closing lid is locked in a position where the upper part of the disc mounting surface is closed, the rotating arm engages the engaging portion. An optical disc player characterized in that the thrust receiver of the rotating arm is spaced apart from the thrust ball so as to press the thrust ball.
