Abstract:
A disk player including a carriage mechanism for basically feeding a selected one of the small diameter or large diameter disks to a turntable and a clamping mechanism for compressing the disk to the turntable, the disk player comprising:a selection arm which abuts against the disk and configured to be turned according to its disk diameter; a shift bar which abuts against the disk and configured to be moved in a disk feeding direction; a startup arm which is engaged with the shift bar and which turns the shift bar to be interlocked so as to be movable in the disk feeding direction; inscribed cam means in which the startup arm is coupled with a clamp arm of the clamp mechanism via a cam, thereby restricting turning, the cam means being capable of engagingly locking the startup arm at a different position depending on the scale of the diameter of the disk to be fed; first biasing means for biasing the shift bar in a direction opposite to the disk feeding direction; and second biasing means for biasing the startup arm, thereby holding the arm at a different engagingly locked position of the inscribed cam, characterized in that the disk moving the shift bar to be pushed against a biasing force of the first biasing means turns the selection arm, thereby controlling the startup arm, and the shift bar is restricted by the startup arm held at either of the engagingly locked positions of the inscribed cam, thereby positioning the centers of disks having their different diameters at the same position.
