Abstract:
A clamp driving device of a compact disk player for an automobile comprising:a player body which is provided therein with a turntable on which a disk is seated, and provided with a driving motor; a clamp arm provided in the player body, which is hingedly connected at its rear portion to the player body and provided at its front portion with a clamp for selectively pressing an upper surface of a disk; a sensor lever coupled to an upper frame of the player body to be moved back and forth, which is biased rearwardly by a lever spring; a locking lever coupled to a lower frame of the player body to be linearly moved back and forth and adapted to selectively check lowering of the clamp arm; a first power transmission mechanism provided at a side frame of the player body, and adapted to selectively transmit turning force of the driving motor by actuation of the sensor lever; and a second power transmission mechanism provided at the side frame of the player body, and adapted to selectively convert the rotational movement of the first power transmission mechanism into linear movement of the locking lever, wherein the clamp arm is coupled under a selective arm and is adapted to be rotated when a disk is loaded, and the sensor lever being provided at its rear portion with a second contact piece to be in contact with the selective arm so that the second contact piece is pushed by the rotating selective arm to move the sensor lever forwardly.
