摘要

Apparatus for film projection of various film systems within the same program, and both for 35 mm bands. As for the 16 mm. That without the need to move the device or change or modify the lens of the base lens, it allows the alternative passage of normal films, anamorphic films (current or future systems) and widescreen films, capable of widening by twenty percent, characterized by having provided in its interior two cores of irregular prisms, of two cousins each, synchronized with each other and coordinated by the double play of a sliding piece and two angled strips, one articulated to the other, and operable by respective external rotary controls, thus being able to regulate the decompression of the anamorphic films from 1 to 1: 2 and up to 1: 3 and make the optical center of the apparatus coincide with the center of the frame, both movements being possible to be combined.
