Claims

[Scope of utility model registration request]

(1) In a moving coil type pickup cartridge in which a microcoil plate formed by forming a spiral pattern of a conductive film on a microsubstrate is directly attached to a regeneration needle, the regeneration needle is formed into an elongated shape and protrudes long above the cantilever. A moving coil type pickup cartridge having a structure in which the micro coil plate is adhesively fixed to a side surface of a portion of the regenerating needle that projects upwardly from the cantilever.

(2) The regenerated needle is a prismatic body, and its - side is fixed to the cantilever in a direction perpendicular to the axis of the cantilever, and the microcoil plate is glued in surface contact with the - side. A moving coil type pickup cartridge according to claim 1, which is a fixed type pickup cartridge.
