摘要

Film guide for projection apparatus, comprising a centering window for delimiting the edges of the image and the position of the film. This window has two frames arranged consecutively in the direction of the light, one acting as a support for the edges of the film and defining the plane of the centering window, and the other one presenting a protuberance in the direction of the support plane of the first frame thus making the film plane. The protuberance also limits the opening of the second frame.
