Claims

[Scope of utility model registration request]

A pressure arm, the base of which is pivotally connected to the top chassis of the compact disc player so as to be rotatable in the direction toward the player body and in the direction away from the player body, and which rotates downward when a tray containing a compact disc enters; and an end of the pressure arm. a presser plate portion that is rotatably connected to the pressure arm and moves up and down in a straight line on the player body in response to the rotation of the pressure arm; and a presser plate portion that is disposed at a position facing the player body. the pressure arm has an absorption mechanism at the base that absorbs variations in the advancing stroke of the tray and adjusts the pressure applied to the compact disc by the clamp mechanism to an appropriate pressure; The clamp mechanism includes a clamper holder provided on the presser plate, a pole press-fitted into the clamper holder on the presser plate side, and a clamper loosely fitted in the clamper holder and pressed by the ball. 1. A compact disk clamp mechanism, characterized in that the clamper holder, the ball, and the clamper are arranged concentrically.
