Abstract

Un aparato impresor perfeccionado, provisto con un dispositivo de impacto que comprende un miembro de impacto que puede ser desplazado desde una posición de descanso en la dirección de un portador de registros por medio de un sistema de propulsión electromecánico, comprendiendo el dispositivo de impacto un transductor que suministra, durante el desplazamiento del miembro de impacto, una señal que es una medida de la velocidad del miembro de impacto, estando conectada una salida de señales de dicho transductor con una primera entrada de señales de un comparador que comprende una segunda entrada de señales que está conectada con un dispositivo de señales de referencia y una salida de señales que está conectada con una primera entrada de señales de un dispositivo de accionamiento eléctrico para dicho sistema de propulsión electromecánico del miembro de impacto.
