Abstract

PURPOSE:To obtain a compact electronic control servo tone arm by forming a thin part at the front or rear part of the horizontal rotating shaft of a tone arm, and by providing a horizontal driving element. CONSTITUTION:The rear end of an arm 1 is inserted into a through hole 24b made in a front swelling part 24a provided atop of a horizontal rotating shaft bearing mem ber 24, and a counter weight 3 is inserted into the rear part 1a of the arm 1. A thin platelike part 24f is formed between the bearing part 24c and swelling part 24a of the horizontal rotating shaft bearing part 24 and in this platelike member 24f, a through hole 24h where a horizontal driving coil 10 is fitted is made; and the horizontal driving coil 10 is fitted in the through hole 24h, and plate or bar-shaped magnets 25 and 26 are fixed on the upper and lower walls 27a and 27b of a vertical rotating shaft bearing member 27 opposite to the horizontal driving coil 10. Thus, the compact constitution of the horizontal driving part of the bearing part of the electro control servo tone arm is realized.
