Abstract
Abstract A container for photographic film has a hollow web connecting a film-supplying chamber with a film-collecting chamber. The front wall of the web has a window which exposes one film frame at a time and such frame is held at a fixed distance from the picturetaking objective of the camera by locating surfaces provided on pins forming part of the rear wall of the web or of a plate which is mounted in the web behind the exposed film frame. The pins extend through openings of the front wall of the web and abut against a stop in the camera body. The plate is biased forwardly by springs installed in a recess of the rear wall and has legs which engage abutments of the front wall to arrest the plate in its foremost position when the container is withdrawn from the camera body.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
178 words
For use in a photographic apparatus having a body including a stop portion located at a predetermined distance from the picture-taking objective, a container for photographic film comprising a film-supplying first portion; a film-collecting second portion; a hollow intermediate portion connecting said first and second portions and having a front wall provided with a window arranged to expose a portion of the film in said intermediate portion, said front wall having a plurality of openings adjacent to said windows; a film-guiding plate movably received in said intermediate portion rearwardly of the film frame behind said window, said plate comprising projections extending forwardly through said openings and having at their front ends locating surfaces; and biasing means reacting against one of said container portions and arranged to urge said plate forwardly so that said locating surfaces of said projections abut, under the action of said biasing means, against the stop portion in the body of the photographic apparatus wherein the container is installed whereby the film frame behind said window is held at a fixed distance from the objective.
Claim 2
Dependent Claim
