Abstract

PURPOSE: To obtain sufficient motional feedback effect by a compact structure, by connection turning an electromagnetic means and a detecting means while using a turning shaft of a tone-arm as a fulcrum.
CONSTITUTION: A horizontal detecting coil 22 and a horizontal drive coil 23 are mounted to both sides of a connecting portion material 19 suspension installed to a lower end of a horizontal turning shaft 10 for a tone-arm 1, a coil 22 constitutes a horizontal speed detector 28 with a yoke 24 and a magnet 25 to detect the speed of a horizontal drive motor 29, and braking is applied to the motor 29, thus preventing resonance at low ranges in the horizontal direction, etc. The coil 23 forms the horizontal drive motor 29 with a yoke 26 and magnets 27a, 27b, and is provided with various kinds of control functions of lead-in, lead-out, return, inside force denial, etc. besides the revolution of the arm 1 in the horizontal direction through the turning shaft 10. Thus, sufficient motional feedback effect can simply be obtained.
