Claims

[Scope of utility model registration request]

(1) A pressing member that cooperates with the turntable to clamp the disk placed on the turntable, and a support shaft that extends parallel to the rotating surface of the turntable and is fixed to a predetermined support mechanism. a support member that is swingably supported between a clamp position and a non-clamp position and that rotatably supports the pressing member at a swing end; and an urging member that biases the support member toward the clamp position. The support member includes a pair of arm portions swingably supported by the support shaft, and bridges the swinging end portions of both arm portions and presses the pressing member at substantially the center thereof. The biasing means is a spring member connected to the swinging end of one of the pair of arm parts, and the biasing means is a spring member connected to the swinging end of one of the pair of arm parts. The synchronizing means extends substantially parallel to the bridge portion, has both ends bent at a substantially right angle, is rotatably supported by the predetermined support mechanism, and has both bent portions connected to the pair of ends. A disc clamping mechanism characterized in that it is a synchronizing bar that engages each swinging end of the arm.

(2) The bent portions at both ends of the synchronization bar smoothly engage with engagement protrusions provided on each swinging end of the pair of arm portions, and the arm portions biased by the spring member. The provided engagement protrusion engages with the bent portion in the biasing direction side by the spring member, and the engagement protrusion provided on the arm portion that is not urged by the spring member engages with the bent portion in the biasing direction. The disc clamping mechanism according to claim 1, wherein the disc clamping mechanism engages on the side opposite to the biasing direction.
