A large gear 12 is rotated in a direction A through a pulley 7, belt 8, pulley 9, worm 10, and gear 11. A lever 16 rotates counterclockwise through a pin 15 to draw a pin 19 into a cut part 102 and a lever 201 is rotated clockwise to close the holder 200. At the same time, a wire lever 39 turnes in a direction E to draw a wire 30 in a direction F, and the holder 29 is drawn in a direction through pulleys 33 and 31 to drawn a disk guide 3 united to the hook holder 29 in a direction G as well; and the disk is fitted to an adapter 54 and pressed against a turntable 4 to stop a motor 6, and the disk 1 is rotated by another motor 55.
