Abstract

PURPOSE: To eliminate the loss at the lead-in and return of a tone arm by providing a rack which is linearly moved forward and backward by a drive gear driven by a turntable shaft and controlling a control cam with this.
CONSTITUTION: A drive gear 152 is provided to the center gear 151 of a turntable shaft 3 and rack 181 provided to a slider 177 is linearly driven by this. On the other hand, a control cam 29 which performs horizontal turning controlling of the tone arm is disposed to the axial center 6. This control cam 29 is rotated forward or backward by the reciprocating movement of the rack 181, whereby the tone arm is controlled of its horizontal turning. Since this enable the rotating center of the control cam 29 to be perfectly aligned to the swing angle center of the tone arm, its mechancial deviation from the tone arm at the lead-in and return may be eliminated and the angular speed of the control cam may be held always constant.
