Abstract

PURPOSE: To make the center of the modulated groove of a record disk coincident with the center of a turntable, by providing a center pin with elasticity in its outer circumferential direction by cutting grooves in the axial direction of the center pin.
CONSTITUTION: The nearly half upper part of a center pin 5 is divided into four elastic pieces 9, which each have elasticity in the outer circumferential direction of the center pin 5. When pressure is applied from the outer circumference, the elastic piece 9 deforms toward the center to decrease the diameter, so even if the center pin 5 is eccentric and warped, each elastic piece 9 absorbs their errors, so that the center of the center pin 5 is coincident with the center of the modulated groove of a record disk.
