Film units, pack and camera

Claim 2

A film unit adapted for an exposure in photographic apparatus to record a latent image processable by a processing composition, the apparatus having a member cooperable with said film unit after the exposure, said film unit comprising: an image-recording unit including a photosensitive element for recording the latent image and a second element permanently secured to said photosensitive element for facilitating distribution of the processing composition over said photosensitive element to effect processing of the latent image: a container releasably coupled to said image-recording unit for supplying the processing composition to said image-recording unit between said photosensitive and second elements: a carrier securely attached to said container and strippably coupled to said image-recording unit to permit separation of said image-recording unit from said carrier and said container; and a leader strippably coupled to said carrier to permit separation of said leader from said carrier and said container.

Claim 3

A film unit as claimed in claim 1 wherein said image-recording unit defines a plane and is strippable from said carrier in response to movement of said carrier in a direction divergent to said plane.

Claim 4

A film unit as claimed in claim 1 wherein said leader is strippably coupled to said carrier at a predetermined area, wherein one of Said leader and said carrier includes means defining an aperture in said area for receiving the cooperable member of the apparatus, wherein the other of said leader and said carrier includes an imperforate portion overlying said aperture, and wherein stripping of said leader from said carrier is facilitated by the cooperable member extending through said aperture to said imperforate portion.

Claim 5

A film unit as claimed in claim 1 wherein said image-recording unit has an underside, wherein said carrier extends along all of said underside, and further comprising means releasably coupled to said image-recording unit for collecting any excess of the processing composition from between said photosensitive and second elements, said collecting means being securely attached to said carrier for separation with said carrier and said container from said image-recording unit and said leader.

Claim 6

A film unit as claimed in claim 4 wherein said carrier is disposed between said leader and said image-recording unit, said container, and said collecting means, as long as said carrier, leader, and image-recording unit remain coupled during processing to prevent wetting of said leader by the processing composition.

Claim 7

A film unit for recording and processing a latent image, said film unit comprising: an elongate first web member including a trailing end portion having an elongate longitudinal opening therein; a second web member including a leading end portion separably coupled in overlapping relationship to said trailing end portion and at least partially covering said longitudinal opening; and an image-recording unit separably coupled in overlapping relationship to said second web member and including a photosensitive element for recording the latent image and a process element permanently secured in superposed relationship to said photosensitive element to facilitate processing of the latent image.

Claim 8

A film unit for recording and processing a latent image, said film unit comprising: an elongate first web member including a trailing end portion having an elongate longitudinal opening therein; a second web member including a leading end portion separably coupled in overlapping relationship to said trailing end portion and at least partially covering said longitudinal opening; and an image-recording unit separably coupled in overlapping relationship to said second web member and including a photosensitive element for recording the latent image and a process element permanently secured in superposed relationship to said photosensitive element to facilitate processing of the latent image.

Claim 9

A film unit as claimed in claim 6 wherein said leading end portion is separably coupled to said trailing end portion by a plurality of relatively small spots of adhesive material disposed in longitudinally spaced relation to said trailing end portion along opposite sides of said longitudinal opening.

Claim 10

A photographic film unit assemblage comprising: a plurality of film units arranged in stacked relation for sequential exposure, each of said film units including an image-recording unit having a photosensitive element for recording a processable latent image and a process element permanently coupled in superposed relationship to said photosensitive element, a container removably coupled to said image-recording unit and having therein a composition for processing the latent image, and a leader removably coupled to said container and said image-recording unit for transporting said container and said image-recording unit within and from said assemblage, said leader including a leading end portion and a trailing end portion, said leader being removably coupled to said container and said image-recording unit at said trailing end portion; and means for removably coupling one of said film units to another of said film units, said coupling means including means for removably adhering the trailing end portion of the leader of said one film unit to the leading end portion of the leader of said other film unit.

Claim 11

A photographic film unit assemblage comprising: a plurality of film units arranged in stacked relation for sequential exposure, each of said film units including an image-recording unit having a photosensitive element for recording a processable latent image and a process element permanently coupled in superposed relationship to said photosensitive element, a container removably coupled to said image-recording unit and having therein a composition for processing the latent image, and a leader removably coupled to said container and said image-recording unit for transporting said container and said image-recording unit within and from said assemblage, said leader including a leading end portion and a trailing end portion, said leader being removably coupled to said container and said image-recording unit at said trailing end portion; and means for removably coupling one of said film units to another of said film units, said coupling means including means for removably adhering the trailing end portion of the leader of said one film unit to the leading end portion of the leader of said other film unit.
