Claims

[Scope of utility model registration request]

In the pick-up arm of a record player; an annular iron piece held at the top of the horizontal rotating part of the pick-up arm; an annular permanent magnet held above the iron piece and facing the same at a predetermined distance; A fishing line-shaped string extends vertically through the center hole of both the permanent magnet and the annular iron piece, and has its upper and lower ends fixed;
Its lower end is fixed to the center of the support base that fixes the pick-up arm to the chassis of the record player, and its upper end is fixed to the center of the magnetic holder above the horizontal rotating part, and the upper and lower ends of the string The intermediate portion is located within the area of magnetic attraction between the permanent magnet and the iron piece, and the horizontal rotating part is supported in a suspended state by the balance between the magnetic attraction and the twisting resistance of the string, and is connected to the outside and the pick-up itself. A pick-up arm having a non-contact rotation mechanism capable of maintaining a stable non-contact rotation state against internal vibrations.
