Abstract

Abstract A camera and photographic method performed by the camera adapted to employ a film assemblage including a plurality of selfdeveloping film units enclosed within a container having an exposure aperture in the forward wall thereof. A film unit is exposed within the container, moved, leading end foremost, from the container through one of a pair of slots at one end of the container and between a pair of pressure applying members for distributing a processing liquid within the film unit to form an image therein; and is then returned to the container through the other slot to a position behind the other film units in which the processed film units is oriented in substantially the same way as originally oriented prior to exposure. The camera includes a compact housing for enclosing the film container and pressure applying members and, following exposure, the film unit is moved in opposite directions outwardly from the film container and housing during distribution of the processing liquid by the pressure-applying members in the opposite direction and then past and to the rear of the pressure-applying members into the housing and film container wherein processing of the film unit, i.e., image formation, is continued toward completion. During exposure, subsequent movement during processing and then return movement into the film container, a film unit is maintained in a generally planar configuration. The camera includes an extensible enclosure for the film units during movement thereof; film engagement members within the enclosure for returning the film unit to the film container following completion of its outward motion; and a door at its opposite end which may be opened to remove a processed film assemblage from the film container through a withdrawal opening at the end thereof to permit viewing of a processed film unit. A film unit may be reintroduced into the film container through the withdrawal opening and the door includes a member for properly locating such a film unit within the container so that it does not interfere with introduction of succeeding units into the container.

The method of producing a plurality of visible photographic images utilizing a film assemblage including a container and a plurality of film units located within a forward portion of said container, each of said film units including at least a photosensitive image-recording layer, said method comprising the steps of: exposing the photosensitive image-recording layer of a film unit of a film assemblage to actinic radiation to form an image in said layer; while maintaining at least an end portion of said film assemblage in an enclosure free of actinic radiation, withdrawing the exposed film unit entirely from the container of said film assemblage at said end thereof anD distributing a processing composition within said film unit to initiate formation of a visible image in said film unit; automatically moving said film unit to a position wherein it may be moved into said container; thereafter introducing said film unit into said container at said end while moving said film unit in a direction substantially opposite to the direction of withdrawal, to a position behind any film unit not previously withdrawn from said container for processing; and during withdrawal, processing and introduction of said film unit, temporarily expanding and reducing the volume of said enclosure as required to accommodate said film unit outside of said container.
Claim 54
Independent Claim 214 words
The method of producing a plurality of visible photographic images utilizing a film assemblage including a container and a plurality of film units located within a forward portion of said container, each of said film units including at least a photosensitive image-recording layer, said method comprising the steps of: exposing the photosensitive image-recording layer of a film unit of a film assemblage to actinic radiation to form an image in said layer; while maintaining at least an end portion of said film assemblage in an enclosure free of actinic radiation, withdrawing the exposed film unit entirely from the container of said film assemblage at said end thereof anD distributing a processing composition within said film unit to initiate formation of a visible image in said film unit; automatically moving said film unit to a position wherein it may be moved into said container; thereafter introducing said film unit into said container at said end while moving said film unit in a direction substantially opposite to the direction of withdrawal, to a position behind any film unit not previously withdrawn from said container for processing; and during withdrawal, processing and introduction of said film unit, temporarily expanding and reducing the volume of said enclosure as required to accommodate said film unit outside of said container.
Claim 55
Dependent Claim 50 words
A photographic method as defined in claim 47 wherein a film unit is introduced completely into said container in two steps, said film unit being moved part way into said container during said first step and being moved completely into said container during introductory movement of a succeeding film unit.
Claim 56
Dependent Claim 26 words
A photographic method as defined in claim 47 wherein a processed film unit is withdrawn from said container at the opposite end of said film assemblage.
Claim 57
Dependent Claim 38 words
A photographic method as defined in claim 49 wherein said processed film unit withdrawn from said container at said opposite end is reintroduced into said container behind any film units not previously withdrawn from said container for processing.
Claim 58
Dependent Claim 31 words
A photographic method as defined in claim 50 wherein said processed film unit withdrawn from said container is reintroduced into said container forwardly of all processed film units within said container.
Claim 59
Dependent Claim 32 words
A photographic method as defined in claim 51 wherein said film unit is introduced into said container in said second direction to the rear of all processed film units within said container.
Claim 60
Dependent Claim 28 words
A photographic method as defined in claim 47 wherein each succedding film unit is introduced in said second direction into said container forwardly of the preceding film unit.
Claim 61
Dependent Claim 28 words
A photographic method as defined in claim 47 wherein each succeeding film units is introduced in said second direction into said container rearwardly of the preceding film unit.
