摘要

Improved film toy projector, of the type comprising a support frame of a driving and transmission optical assembly that animates a film drag system, essentially characterized in that the output shaft of movement is topped by a cylindrical head from whose front emerge diametrically opposed pivots that constitute axial driving means for a tubular bushing containing the cylindrical head and that in its outer mouth has an extension that constitutes an axis by which the tubular bushing freely rotates in a housing provided in a housing and by which he shows solidarity with a drum that accompanies him in his turn; said drum being provided with peripheral lugs of a pitch equal to the passage of the perforations of the film; with the particularity that the drum is provided with two pairs of guide rollers located on the plane not affected by the lugs, which constitute pressure elements of the film when it is tangentially dragged by the drum; a retention stump for a flywheel which fixed to the drum rotates with it and limits the transverse displacement of the film is provided in the drum.
