Abstract
Abstract A photographic camera for printing two different kinds of data upon one sole image carrier comprises a pre-exposure station in which a mask is printed upon the image carrier. After such pre-exposure the image carrier is moved into the focal plane of two optical systems. The first of said systems projects an image of data located inside the camera (such as data printed or typewritten on a card) on a primarily unexposed area of the image carrier, whereas the second optical system projects an image of data located outside the camera (such as the image of a person) on another primarily unexposed area of the image carrier. The image carrier is subsequently developed in a processing station which itself may also be provided in the camera. Photographic materials of the diffusion transfer reversal type are used advantageously in combination with the camera.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
161 words
A photographic camera for exposing a photographic light-sensitive material simultaneously to different subjects to form images thereof at different locations on such material, which camera comprises a storage station containing a roll of photographic material, at least two exposure stations arranged in succession, one of said stations incorporating masking means adapted to shield at least two areas of the material while the remainder thereof is being exposed to light at that station, the other station having optical projecting means for projecting an image of one subject onto one of said initially shielded areas and an image of at least one other subject onto another of such areas of the photographic material, transport means for delivering predetermined lengths of photographic material from said roll to said exposure stations, severing means actuatable to sever said predetermined lengths of photographic material and web engaging means upstream of said severing means intermittently operable to immobilize the photographic material during the actuation of said severing means.
Claim 2
Dependent Claim
161 words
A photographic camera for exposing a photographic light-sensitive material simultaneously to different subjects to form images thereof at different locations on such material, which camera comprises a storage station containing a roll of photographic material, at least two exposure stations arranged in succession, one of said stations incorporating masking means adapted to shield at least two areas of the material while the remainder thereof is being exposed to light at that station, the other station having optical projecting means for projecting an image of one subject onto one of said initially shielded areas and an image of at least one other subject onto another of such areas of the photographic material, transport means for delivering predetermined lengths of photographic material from said roll to said exposure stations, severing means actuatable to sever said predetermined lengths of photographic material and web engaging means upstream of said severing means intermittently operable to immobilize the photographic material during the actuation of said severing means.
Claim 3
Dependent Claim
33 words
A photographic camera according to claim 1, wherein said first exposure station comprises a light-tight chamber housing a source of light for exposing unmasked areas of a photographic material at said first station.
Claim 4
Dependent Claim
27 words
A photographic camera according to claim 1, wherein said masking means is such as to have a vignetting effect on at least one of the masked areas.
Claim 5
Dependent Claim
40 words
A photographic camera according to claim 1, wherein said photographic material is in roll form and said transporting means serves to transport successive lengths of photographic material from a said roll and successively through said first and second exposure stations.
Claim 6
Dependent Claim
45 words
A photographic camera according to claim 1, and including a holder for holding at least one subject in the form of graphic matter in a position for projection of an image thereof onto a said area of a photographic material at said second exposure station.
Claim 7
Dependent Claim
37 words
A photographic camera according to claim 5 including at least one source of light for reflex-exposing a said area of a photographic material to a subject in the form of graphic matter when present in said holder.
Claim 8
Dependent Claim
48 words
A photographic camera according to claim 1, and incorporating at least one light source for illuminating a subject located at a position spaced forwardly from the camera during projection of an image of such subject onto a said area of a photographic material at said second exposure station.
Claim 9
Dependent Claim
48 words
A photographic camera according to claim 7, wherein said light source for reflex exposing said area of a photographic material, and said light source for illuminating a subject located at a position spaced forwardly from the camera, are connected into an operating circuit for simultaneously operating such sources.
Claim 10
Dependent Claim
21 words
A photographic camera according to claim 1, which has a built-in processing station in order to process the exposed recording material.
Claim 11
Dependent Claim
20 words
A photographic camera according to claim 1 used with a photographic recording material which is a negative diffusion transfer material.
Claim 12
Dependent Claim
51 words
A photographic apparatus according to claim 10 in which means is provided for introducing a sheet of positive diffusion transfer material in order to contact the active layer of the latter with the recording layer of the said negative diffusion transfer material in order to form a sandwich to be developed.
Claim 13
Dependent Claim
23 words
A photographic camera according to claim 11 which is provided with a slot for guiding the processed recording material out of the apparatus.
Claim 14
Dependent Claim
26 words
A photographic camera according to claim 1, in which a telemetering system is provided working in combination with one optical system of the second exposure station.
Claim 15
Dependent Claim
29 words
The camera of claim 1 wherein said web engaging means comprises means for bringing said photographic material into intimate contact with said masking means at said one exposure station.
