Title:
PICKUP CARTRIDGE
Document Type and Number:
Japanese Patent JPS62173601
Kind Code:
A
Abstract:

PURPOSE: To make noiseless reproducing possible by coating surfaces of a stylus tip and a cantilever with a conductive material and using a conductive adhesive.

CONSTITUTION: Surfaces of a stylus tip 2 and a cantilever 1 are coated with a conductive material and a conductive adhesive 15 is used to connect electrically individual parts. Since the electric charge charged on a record is migrated from the stylus tip 2 to the earth through the cantilever 1, a wire 6, a supporting pipe 7, and a sleeve 8, the electric charge charged on the record disk is not discharged at a high voltage and has not an influence upon a signal output path. Though the surface of the stylus tip 2 is coated with the conductive material, the electric charge on the record disk is migrated to the cantilever 1 with a slight potential because the distance from the surface of the record to that of the cantilever 1 is very short, and the influence upon the signal output path is reduced.
