Abstract

PURPOSE: To turn an arm up to an arbitrary position and stop without providing brake or the like by turning the manget fitted to the arm shaft together with the arm shaft based on the rotating megnetic field by two coils.
CONSTITUTION: An arm 9 is provided to an arm shaft 6 vertically turnably by pivot support and horizontally turnably together with the arm shaft 6. An approximately cruciform stator core 10 is fixed to the bottom of an arm fixing base 4 and is wound with coils L1,L'1, L2, L'2, which are then connected to volume controls VR1, VR2. At the volume controls VR1, VR2 are operated, a yoke 11 and magnet 13 turn together with the arm shaft 6, thereby enabling the arm 9 to be turned up to a desired position on the record disc.
