PURPOSE:To prevent parasitic motion by supporting a weight member in a housing freely floatably, and by fixing this housing at an adequate position in a pickup system. CONSTITUTION:Near the center of the inside bottom part 10A of a main body 10, a bar body 12 is stood and the nearly plane bottom part 10A is applied with lubricating oil 14, through which an annular weight member 13 is supported. The weight member has about 200mg-5g weight and about 1cm diameter. A fixing device 15 of an adhesive tape is provided at the outside bottom part 10B of the main body 10 and stuck, for example, to the top surface, etc., of a head shell. Consequently, the weight member sets itself in motion repulsing parasitic motion to absorb energy, which corresponds to the speed of the parasitic motion, by its motion proportional to the speed. Since the energy of the parasitic motion varies a little with stylus force, the weight member is varied necessarily corresponding the stylus force. |
