Abstract
PURPOSE: To reduce the inertial mass of the tone arm, by turning the tone arm horizontally and vertically by one driving means, in the electric servo for the tone arm.
CONSTITUTION: Tone arm 1 is turned horizontally around axis Y-Y' of horizontal turning shaft 4 and is turned vertically around axis X-X'. At the tip of arm driving shaft 5, driving coils 6 and 6a are arranged on coil supporting plate 7, and ring magnet 11 is provided. The tone arm is turned vertically when currents in the same direction are flowed to both coils, and the tone arm is turned horizontally when currents in directions opposite to each other are flowed to them.
