EP0420127A1 — Photograpic film package

Claim 1

Independent Claim 163 words

A photographic film package comprising a spool having wound round it a photographic film and a cartridge rotatably containing the spool carrying the photographic film, said cartridge having a film outlet for taking out and in the photographic film wherein said cartridge has a means for controlling the position thereof when the photographic film package is loaded in a camera such that the aforesaid film outlet is kept in the plane including the exposure stage in the camera and the direction of taking out or in the photographic film in the camera becomes parallel to the winding direction of the photographic film in the camera, and the photographic film has light-sensitive layers having a total layer thickness of not thicker than 30 µm on one side of a transparent support and a back layer containing a hydrophilic polymer having a layer thickness of from 15% to 90% of the total layer thickness of the light-sensitive layers on the other side of the support.

Claim 2

Dependent Claim 163 words

A photographic film package comprising a spool having wound round it a photographic film and a cartridge rotatably containing the spool carrying the photographic film, said cartridge having a film outlet for taking out and in the photographic film wherein said cartridge has a means for controlling the position thereof when the photographic film package is loaded in a camera such that the aforesaid film outlet is kept in the plane including the exposure stage in the camera and the direction of taking out or in the photographic film in the camera becomes parallel to the winding direction of the photographic film in the camera, and the photographic film has light-sensitive layers having a total layer thickness of not thicker than 30 µm on one side of a transparent support and a back layer containing a hydrophilic polymer having a layer thickness of from 15% to 90% of the total layer thickness of the light-sensitive layers on the other side of the support.

Claim 3

Dependent Claim 118 words

A photographic film package for insertion within a cartridge chamber of a camera, said package being of the type having a housing, a film wound on a spool within said housing, and a film port for drawing said film out of said housing and for retracting said film into said housing, the improvement comprising: positioning means on said housing for cooperating with positioning means in said cartridge chamber for fixedly orienting said package within said chamber when said package is placed within said chamber to insure that said film exiting through said port towards an exposure position within said camera exits parallel to the winding direction of said camera so as to exhibit flatness at said exposure position.

Claim 4

Dependent Claim 118 words

A photographic film package for insertion within a cartridge chamber of a camera, said package being of the type having a housing, a film wound on a spool within said housing, and a film port for drawing said film out of said housing and for retracting said film into said housing, the improvement comprising: positioning means on said housing for cooperating with positioning means in said cartridge chamber for fixedly orienting said package within said chamber when said package is placed within said chamber to insure that said film exiting through said port towards an exposure position within said camera exits parallel to the winding direction of said camera so as to exhibit flatness at said exposure position.

Claim 5

Dependent Claim 49 words

The photographic film package of claim 2 wherein said positioning means comprises at least two flat surfaces on the outer surface of said package to mate with corresponding flat surfaces on the inner walls of said cartridge chamber so as to prevent rotation of said package within said chamber.

Claim 6

Dependent Claim 47 words

The photographic film package of claim 2 wherein said positioning means comprises at least one projection on the outside of said package to mate with a corresponding depression on an inside wall of said cartridge chamber so as to prevent rotation of said package within said chamber.

Claim 7

Dependent Claim 40 words

The photographic film package of claim 2 wherein said positioning means comprises the photographic film package of claim 4 wherein said package has two end walls and said at least one projection is on an end wall of said package.

Claim 8

Dependent Claim 70 words

The photographic film package as claimed in claim 2 wherein the improvement further comprises, said film having light-sensitive layers with a total layer thickness of not greater than 30 µm on one side of a transparent support and a back layer containing a hydrophilic polymer having a layer thickness of from 15% to 90% of the total layer thickness of the light-sensitive layes on the other side of the support.
