Abstract
Abstract A drop-in cassette for photographic roll film wherein the intermediate section which is located behind the film gate when the cassette is inserted into a camera body carries one or more elastic flaps which engage a first internal surface of the camera body to thereby urge an exposed surface of the intermediate section against another internal surface of the camera body and to thus insure that the cassette is maintained in an optimum position with respect to the film gate, with respect to the parts of the film transporting mechanism, and/or with respect to a feeler which bears against the front side of film in the intermediate section and penetrates into an oncoming perforation of the moving film during film transport to thereby initiate a termination of the film transport at the exact moment when the foremost unexposed film frame is in accurate register with the film gate. The flap or flaps may engage and be deformed by a portion of the camera body, by a portion of the movable cover of the camera body or by a portion of the film gate.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
138 words
A container for a supply of photographic roll film for use in photographic apparatus of the type having a chamber for reception of the container and bounded by a plurality of internal surfaces, said container comprising a casing including a first section for the storage of unexposed film and a second section for the storage of exposed film whereby a portion of said supply of film extends between said sections and is located in a predetermined plane, said casing further having an exposed surface which is at least substantially normal to said plane and said container further comprising at least one elastic portion arranged to engage and to be deformed by one of said internal surfaces of a photographic apparatus whose chamber receives said container and to thereby urge said exposed surface against another of said internal surfaces.
Claim 2
Dependent Claim
138 words
A container for a supply of photographic roll film for use in photographic apparatus of the type having a chamber for reception of the container and bounded by a plurality of internal surfaces, said container comprising a casing including a first section for the storage of unexposed film and a second section for the storage of exposed film whereby a portion of said supply of film extends between said sections and is located in a predetermined plane, said casing further having an exposed surface which is at least substantially normal to said plane and said container further comprising at least one elastic portion arranged to engage and to be deformed by one of said internal surfaces of a photographic apparatus whose chamber receives said container and to thereby urge said exposed surface against another of said internal surfaces.
Claim 3
Dependent Claim
45 words
A container as defined in claim 1, wherein said casing further comprises an intermediate section extending between said first and second sections, said exposed surface being provided on said intermediate section and said portion of said supply of film being confined in said intermediate section.
Claim 4
Dependent Claim
32 words
A container as defined in claim 1, wherein said casing has two substantially parallel outer sides and said exposed surface forms part of or is parallel to one of said outer sides.
Claim 5
Dependent Claim
20 words
A container as defined in claim 1, wherein said elastic portion is a projection which is integral with said casing.
Claim 6
Dependent Claim
33 words
A container as defined in claim 1, wherein said supply of film as a row of perforations adjacent to one marginal portion thereof, said exposed surface being adjacent to said one marginal portion.
Claim 7
Dependent Claim
51 words
A container as defined in claim 1, wherein said casing has two substantially parallel exposed surfaces and said elastic portion is provided in the region of one of said exposed surfaces to bias the other of said exposed surfaces against said other internal surface while engaging with said one internal surface.
Claim 8
Dependent Claim
61 words
A container as defined in claim 6 for use in a photographic apparatus having a film gate including parallel first and second outer faces which respectively constitute said one and said other internal surface, said supply of film having a row of perforations adjacent to one marginal portion thereof and said other exposed surface being adjacent to said one marginal portion.
Claim 9
Dependent Claim
33 words
A container as defined in claim 7, wherein said casing has two substantially parallel outer sides and each of said exposed surfaces is parallel with or forms part of a different outer side.
Claim 10
Dependent Claim
40 words
A container as defined in claim 7, wherein said casing further comprises an intermediate section for said portion of photographic film, Said intermediate section having two substantially parallel panels and said exposed surfaces constituting the inner surfaces of said panels.
Claim 11
Dependent Claim
58 words
A container as defined in claim 1 for use in a photographic apparatus having a film gate including parallel first and second outer faces one of which constitutes said other internal surface, said supply of film having a row of perforations adjacent to one marginal portion thereof and said exposed surface being adjacent to said one marginal portion.
Claim 12
Dependent Claim
79 words
A container as defined in claim 10, wherein said casing further comprises an intermediate section for said portion of photographic film and said section includes a panel having an inner surface constituting said exposed surface and a outer surface, said elastic portion being provided in the region of said outer surface and being arranged to bias said inner surface against said one outer face of the film gate while engaging with and being deformed by said one internal surface.
