Claims

[Scope of utility model registration request]

(1) It is attached to an arm that reciprocates between the inner collet chuck of the cassette case inserted into the cassette case mounting part and the turntable, and the compact disc fitted in the inner collet chuck is grabbed and turned. A compact disc playback device comprising a chuck member that is set at a performance position on a table, grips the compact disc on the turntable again, and frictionally fits the compact disc on the inner collet chuck, the chuck member a button that is attached to the frame substrate of the arm so as to be movable up and down, and that can press the inner collet chuck from above to reduce its diameter;
a spring that normally urges the button downward; a plurality of fingers arranged swingably around the button so as to be removably fit into the center hole of the compact disc; and each of the fingers. a radially extensible ring spring fitted on the outside of the button; and a lifting means for lifting the button to a predetermined height position against the spring, the button being pushed to a downward position by the spring. When the bushing is lowered, the pivot point of the bushing relative to the finger is below the ring spring, and the lower end of each finger is biased to expand radially outward by the diameter reduction action of the ring spring. When the button is engaged with the inner edge of the center hole of the compact disk and the lift means raises the button to a predetermined height position, the swing fulcrum is above the ring spring, and the lower end of each finger is above the ring spring. A compact disc playback device characterized in that the compact disc is biased radially inward by the diameter reduction action of the compact disc to release the constraint on the compact disc.

(2) Utility model registration Claim (1) is characterized in that the bushing is made of a cylindrical body with a bottom, and a flange is formed at the opening thereof to serve as a rocking support for the finger. Compact disc playback device.

(3) Utility model registration Claim (1) In claim (1), the lifting means includes a tapered surface formed on the button side;
A compact disc playback device comprising: a lift lever that slides along the frame substrate, comes into contact with the tapered surface, and uses its vertical component to lift the button against the spring.

(4) Utility model registration In claim (1), the frame substrate of the arm has a driven ring that is concentrically arranged with respect to the bushing and can elastically abut on the surface of the compact disk and rotate with it. A compact disc playback device characterized in that:

(5) Utility model registration Claim (1) or (2), characterized in that the lower end of each of the fingers is provided with a U-shaped groove that engages with the inner edge of the center hole of the compact disc. Compact disc playback device.
