PURPOSE:To facilitate the regular positioning with a flat damper and to maintain a proper stylus height from the record surface without increasing the length of the cantilever, by forming an oblique center hole to a plate type oscillator and connecting the rear end of a cantilever to said center hole. CONSTITUTION:A plate type magnet 13 is attached to a cantilever 12 by fitting the rear end of the lever 12 into an oblique hole 13a formed at the center of the magnet 13. A supporting pipe 15 is attached to a supporting line 16 led out from the rear end of the lever 12 having a stylus tip 11 at its tip and the magnet 13 at the other end respectively. Then the pipe 15 is put into a center hole 17a of a sleeve 17 via a damper 14. In such a way, the damper 14 is properly compressed by the line 16 to give a vibration fulcrum to the magnet 13, and the magnet 13 is set within a yoke 18 wound by a generating coil 19. Thus it is possible to set the magnet 13 provided at the rear end of the lever 12 between pole pieces of the yoke 18 with no inclination by means of a flat damper 14. |
