Projector of films, characterized in that directly, in the crank that activates the mechanism that gives rise to the displacement of the film, a dynamo is coupled, which produces the electrical energy necessary to effect the projection; by means of a toothed wheel, integral with the axis of the crank, which by a transmission chain moves the pinion that gives rise to the advance of the film, from whose axis a wheel is integral, which by belt drives the pulley of the dynamo.
