PURPOSE:To suck and fix a record disk to/on a disc body by sucking air through the center hole of the record disc. CONSTITUTION:The disc body 12 is set up on a turntable 1 by inserting a center spindle 9 into the center hole 13 of the disc body 12. A record 3 is put on the disc body 12 and then suction adaptor 23 is set up on the upper surface of a label part 4 of the record 3. If air is sucked to reduce pressure under said state, air sealed by the record 3 passes through an air room 16, a suction valve 19 and the gap between the center spindle inserting hole 10 of the record 3 and the center spindle 9 to be sucked into a case 24. Consequently said space is made negative pessure, and the record is fixed by sucking to/on the disc body 12. |
