摘要

Device for projecting on a screen of information in continuous succession, characterized in that it comprises a non-deformable frame constituted by two parallel beams, mounted rigidly by two connecting flanges perpendicular to the beams; a rectangular transparent plate, which forms a body with the frame arranged between the longitudinal members, with fixing means on the connecting flanges; and a film on which the texts that parade before the plate inscribe, avoiding their contact.
