Abstract

PURPOSE:To attract and hold the record disk to the surface of the turntable, by forming the negative pressure generating part at the necessary position on the surface of the turntable in order to generate the negative pressure. CONSTITUTION:Turntable 10 is fixed to shaft 1 of the vertical player. When record disk R is applied to the player by fitting center hole (r) to center spindle 12 and on the surface of elastic mat 14 of turntable 10, projected edge 15 is formed beteen the record disk and the surface of mat 14 along with the gap, i.e., negative pressure generating part P formed via concave groove 16 and the oblique surface. Under these conditions, the air sucking device is actuated. As a result, negative pressure tank room (a) within casing 13 features the negative pressure since the air is sucked through intake 18 and via air pipe 19 each. Thus disk R is attracted and held on the surface of mat 14 and then turned in a body with turntable 10 to carry out the record reproduction.
