Abstract

Una cabeza electrostática de escritura que comprende una placa aislante, plana, dotada de pistas conductoras que forman electrodos de escritura y conductores de conexión para estos electrodos de escritura, consistiendo dichos electrodos de escritura en partes extremas mutuamente paralelas de las pistas conductoras que terminen en un borde de la placa caracterizada porque la cabeza consiste en dos placas provistas de un conexionado superficial, comprendiendo el conexionado superficial de cada placa varias franjas conductoras mutuamente paralelas que están situadas a igual distancia unas de otras y que terminan en un borde de la placa, estando conectadas dichas placas entre si de tal manera que sus lados provistos de conexionado superficial estén enfrentados.
