Abstract
Dispositivo proyector de películas cinematográficas provisto con un rodillo impulsor intermitentemente impulsado para la película y un obturador continuamente impulsado para interceptar periódicamente los haces luminosos para la iluminación de un cuadro de película, en que en la transmisión entre el rodillo impulsor y el obturador está provista una rueda dentada como un miembro de acoplamiento que en su circunferencia está provista con dientes dispuestos en un ángulo tal que durante el funcionamiento una fuerza axial es ejercida sobre la rueda dentada y absorbida elásticamente, caracterizado por el hecho de que la rueda dentada está rígidamente montada sobre su eje y está provista, entre su cubo y el borde dentado, con una porción de una elasticidad tal que una fuerza axial de 30kgrs, produce una desviación de por lo menos 1mm.
