摘要

A box that can be coupled to an apparatus for viewing cinematographic films, characterized in that it is constituted of a container piece that contains, at one end, a freely rotating cylinder in which an endless cinematographic film is wound; a guide and drag device for directing and dragging said film towards a window made in the opposite end wall to which the winding is, and a reflector element of light beams placed opposite said window to direct the beams towards it, such device of guide and drag being constituted by a combination of partitions and crazy cylinders suitably located to cause the perforations of the film to mesh in the teeth of a toothed driving cylinder, driven by the apparatus to which the cassette is coupled, and thus dragged developing advance towards the window against which it is pressed by two crazy cylinders attached to corresponding springs, then moving towards the winding roll on it, such advance occurring to intermittences so that at each tooth step of the drag cylinder passes a frame in front of the window and in front of the light beam reflected by the refl element ector and a lid part, which fits the container part, in which there is a set of partitions and complementary appendages of the guide device of the film directing it in its development, and winding, and a window in correspondence with the element reflector of the container part.
