PURPOSE:To simplify the taking in and out compact disk to a compact disk storage case by providing a notched form stretching from the inner peripheral surface of the disk hole to the outside. CONSTITUTION:The proper number of notched forms 4 are notched in the inner peripheral surface of a hole 2 for positioning disk. Then, one of pieces 1 becomes smooth by detached from others while remaining one part. In that case, at the time of entering along a taper part 5 in the setting process to a player driving shaft 6, the one piece 1 of the part moves upward and downward and set with no resistance even when there is a rack. Thus, the clearance between the disk hole 2 and the driving shaft 6 is minimized, eccentricity is cancelled, and a signal is read more faithfully so that the reliability of the player in improved. |
