MICROFILM CASSETTE AND THE PROJECTION APPARATUS FOR THE VIEWING OF SAME ABSTRACT OF THE DISCLOSURE: The cassette is fitted with two magazines which each have in its center a spool axis or shaft. The width of the cassette being slightly superior to the width of the microfilm. The two magazines are joined by a pair of separate plates, which extend the walls of the magazines so that the film runs between the two plates, the central zone of the two plates being transparent. The width of the interval between the two plates is small, so as to press the film and thus accurately to place its portion to be viewed on the light trajectory. The apparatus for the use of the cassette makes it possible to cause the film to circulate in both directions, and to displace the cassette in the reverse direction.
