Abstract

PURPOSE:To make light the mass of cartridge and to perform the reproduction with high fidelity, by removing the magnetic pole piece from a power generating mechanism of a cartridge. CONSTITUTION:An armature 2 is supported by a main body 1 of cartridge. The armature 2 is provided with the first leg 5a leading to axial direction of a cunti- lever 3, the second and third legs 5b, 5c orthogonal to the leg 5a. Each leg is made of material with high magnetic permeability, and it is magnetically coupled each other. Since a magnetic means 17 is opposingly located to the armature 2 and no magnetic pole piece is used, the mass of the cartridge can be made light.
