摘要

Projection device of continuous development with optical compensation by multiple objectives characterized by comprising two bands of film, usually normal, of equal length, whose automatic projection is uninterrupted; these two bands of film-one of which is rolled while the other is developed-that parade with preference horizontally, in two corridors of suitable form, of window corresponding to a double image, arranged in front of two border projection lanterns, are projected alternatively on the screen by means of the multi-objective crown common to these two lanterns and to these two aisles and rotating between them; and means capable of simultaneously rotating jagged drums that scratch the two bands of film -whose development causes by suitable organs, the rotation of the multi-objective crown and that of an anti-flashing device- and the discs supporting the bands.
