Abstract
Abstract A photographic camera is adapted to receive a film container which supports a filmstrip having a normally curled leader extending from the film container. As the film container is loaded in the camera, means on the camera deflects successive longitudinal edge portions of the curled leader into a substantially straight line, incrementally uncurling the film leader, and guides the uncurled leader, straightened edge portions first, into a film passageway in the camera.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
81 words
In photographic apparatus adapted to receive a film container supporting a filmstrip having a normally curled leader extending from the container, the improvement comprising: means defining a film passageway adapted to receive a substantially uncurled film leader longitudinal edge first as a film container is moved into said photographic apparatus; and means, effective upon movement of the film container into said photographic apparatus, for substantially uncurling the film leader and for guiding the uncurled leader longitudinal edge first toward said passageway.
Claim 2
Dependent Claim
81 words
In photographic apparatus adapted to receive a film container supporting a filmstrip having a normally curled leader extending from the container, the improvement comprising: means defining a film passageway adapted to receive a substantially uncurled film leader longitudinal edge first as a film container is moved into said photographic apparatus; and means, effective upon movement of the film container into said photographic apparatus, for substantially uncurling the film leader and for guiding the uncurled leader longitudinal edge first toward said passageway.
Claim 3
Dependent Claim
43 words
The improvement as recited in claim 1, wherein said uncurling means includes means located to extend across a longitudinal edge of the film leader as the film container is moved into said photographic apparatus, for deflecting the longitudinal edge to uncurl the leader.
Claim 4
Dependent Claim
90 words
In photographic apparatus adapted to receive a film container supporting a filmstrip having a normally curled leader extending from the container, the improvement comprising: means defining a film passageway adapted to receive a substantially uncurled film leader longitudinal edge first as a film container is moved into said photographic apparatus; and means, effective upon moving the film container into said photographic apparatus, for substantially uncurling successive longitudinal edge portions of the film leader to incrementally uncurl the leader and for guiding the leader, uncurled edge portions first, toward said passageway.
Claim 5
Dependent Claim
90 words
In photographic apparatus adapted to receive a film container supporting a filmstrip having a normally curled leader extending from the container, the improvement comprising: means defining a film passageway adapted to receive a substantially uncurled film leader longitudinal edge first as a film container is moved into said photographic apparatus; and means, effective upon moving the film container into said photographic apparatus, for substantially uncurling successive longitudinal edge portions of the film leader to incrementally uncurl the leader and for guiding the leader, uncurled edge portions first, toward said passageway.
Claim 6
Dependent Claim
29 words
The improvement as recited in claim 3, wherein said uncurling means is adapted to uncurl successive longitudinal edge portions of the film leader increasingly distant from the film container.
Claim 7
Dependent Claim
90 words
In photographic apparatus adapted to receive a film container supporting a filmstrip having a normally curled leader extending from the container, the improvement comprising: means defining a film passageway adapted to receive a substantially uncurled film leader longitudinal edge first as a film container is moved into said photographic apparatus; and means, effective upon moving the film container into said photographic apparatus, for substantially straightening successive longitudinal edge portions of the film leader to incrementally uncurl the leader and for guiding the leader, straightened edge portions first, into said passageway.
Claim 8
Dependent Claim
90 words
In photographic apparatus adapted to receive a film container supporting a filmstrip having a normally curled leader extending from the container, the improvement comprising: means defining a film passageway adapted to receive a substantially uncurled film leader longitudinal edge first as a film container is moved into said photographic apparatus; and means, effective upon moving the film container into said photographic apparatus, for substantially straightening successive longitudinal edge portions of the film leader to incrementally uncurl the leader and for guiding the leader, straightened edge portions first, into said passageway.
Claim 9
Dependent Claim
46 words
The improvement as recited in claim 5, wherein said straightening means includes a substantially straight member for deflecting into a substantially straight line successive longitudinal edge portions of the film leader increasingly distant from the film container as the container is moved into said photographic apparatus.
Claim 10
Dependent Claim
43 words
The improvement as recited in claim 6, wherein said straight member is inclined at an oblique angle with the successive edge portions of the film leader and extends across the successive edge portions as the film container is moved into said photographic apparatus.
Claim 11
Dependent Claim
120 words
In photographic apparatus adapted to receive a film container supporting a filmstrip having with a normally curled leader extending from the container, the improvement comprising: means defining a film passageway adapted to receive a substantially uncurled film leader longitudinal edge first as a film container is moved into said photographic apparatus; elongate means, inclined at an oblique angle with successive longitudinal edge portions of the film leader increasingly distant from the film container as the container is moved into said photographic apparatus, and effective upon said movement of the container, for deflecting the successive edge portions into a substantially straight line to incrementally uncurl the leader; and means for guiding the uncurled leader, straightened edge portions first, into said passageway.
Claim 12
Dependent Claim
120 words
In photographic apparatus adapted to receive a film container supporting a filmstrip having with a normally curled leader extending from the container, the improvement comprising: means defining a film passageway adapted to receive a substantially uncurled film leader longitudinal edge first as a film container is moved into said photographic apparatus; elongate means, inclined at an oblique angle with successive longitudinal edge portions of the film leader increasingly distant from the film container as the container is moved into said photographic apparatus, and effective upon said movement of the container, for deflecting the successive edge portions into a substantially straight line to incrementally uncurl the leader; and means for guiding the uncurled leader, straightened edge portions first, into said passageway.
Claim 13
Dependent Claim
56 words
The improvement as recited in claim 8, wherein said guiding means includes a substantially flat surface defining an access to said film passageway for receiving the uncurled leader, straightened edge portions first, and said elongate means includes a substantially straight edge-defining member adjacent said flat surface for deflecting the respective edge portions onto said flat surface.
Claim 14
Dependent Claim
24 words
The improvement as recited in claim 9, wherein said flat surface is adapted to support the uncurled leader to prevent the leader from re-curling.
