Abstract

DISPOSITIVO E ARRASTRE DE PELICULA CON SECUENCIA DE IMAGENES SUCESIVAS EN MAQUINAS FOTOGRAFICAS. CONSTA DE UN DISCO OBTURADOR MOVIDO MEDIANTE UNOS EMGRANAJES CONICOS Y UN EJE, DE FORMA SINCRONIZADA CON EL ARRASTRE DE LA PELICULA, LA CUAL CORRE A TRAVES DE CUATRO CARRETES MOVIDA POR UN SISTEMA DE ENGRANAJES, UNO DE LOS CUALES TIENE UN ARCO CIRCULAR SIN DIENTES PARA ASEGURAR LA DETENCION DEL ARRASTRE CUANDO EL OBTURADOR ESTA ABIERTO EN CADA POSICION. TANTO EL DISCO OBTURADOR COMO LOS ENGRANAJES DE ARRASTRE DE LA PELICULA SE MUEVEN POR UNA CORREA DENTADA IMPULSADA, A SU VEZ, POR UN MOTOR ELECTRICO ACCIONADO POR UN INTERRUPTOR. EXISTEN DIVERSAS VARIANTES CONSTRUCTIVAS.
