Abstract

PURPOSE:To simplify the construction, by commonly using a Hall element for generation of horizontal speed detecting control voltage for detection of lead-out position of a tone arm. CONSTITUTION:To plate part 24f of a horizontal turning bearing 24 is made a through-hole 24h where a horizontal driving coil 10 is inserted, the coil 10 is inserted in the hole 24h, and a horizontal speed detecting Hall element 25 is provided on an arm 25a projected from a bearing 24c. A magnet 26a is implanted to the rear arm 1a or the like by opposing to it. A plate or rod magnet 26 opposing to the driving coil 10 is fixed to upper and lower side walls 27a, 27b respectively. Thus, it is not necessary to separately provided a horizontal position detector, allowing simplify the construction.
