Abstract

PURPOSE:To adhere a record disc closingly, by providing an external circumferential circular ring step and a central step contacted with a record disc on the upper surface of a turntable, and circular ring grooves, radial grooves and through-holes linked with suction holes between both the steps. CONSTITUTION:A plurality of circular grooves 10a and radial grooves 10b are formed on the upper surface of a turntable 10, an external circumference of a record disc 13 is brought into contact with an external circumference side circular ring step 10f and the center part is brought into contact with a center step 10c. A plurality of through-holes 10d prolonged to a rotating shaft 12 are formed around the step 10c, and a circular groove 14a is formed on the upper surface of a sucking adaptor 14 so that the groove can be opposed to the lower end opening of the through-holes 10d. The record disc 13 is placed on the turntable 10 and a suction pump is operated, then the air in the grooves 10a and 10c moves to the center and is discharged from the through-hole 10d through the circular ring groove 14a and suction holes 14b and the record disc 13 is sucked on the turntable 10.
