  • Patent number: 6342331
    Abstract: The invention relates to a diffusion transfer type film unit which can produce the same two picture prints at one shot of photographing. The film unit comprises a first sheet and a second sheet. The first sheet includes at least transparent sheet through which exposure is made. The second sheet includes at least photosensitive layer. In one embodiment, two dye image receiving layers are disposed on the first and second sheets separately and a peeling-off layer is disposed between the photosensitive layer and a dye image receiving layer on the second sheet. In another embodiment, two dye image receiving layers are disposed on the same second sheet and a peeling-off layer is disposed therebetween. In both embodiments, the second sheet is capable of being separated into two parts at the interface of the dye image receiving layer and the peeling-off layer. After development, respective picture images on the two dye image receiving layers can be viewed by separating the second sheet into two parts.

  • Publication number: 20010046031
    Abstract: A film image input system is disclosed which can use a film cartridge constructed in such a manner that it requires a small space for storing a developed still photo film and also can protect the film against dust and damage, and also which allows the film cartridge to be mounted into a cartridge mounting part very simply and positively. The film image input system 1 is arranged such that it reproduces the image of the developed still photo film 2 on a video monitor 18. The system uses a film cartridge 6 which comprises a cartridge main body having an outlet opening 7 for sending out the film 2 in the longitudinal direction thereof, a single spool which fixes one end of the film 2 in the longitudinal direction thereof and round which the whole length of the film 2 can be wound, and support means for supporting the spool in such a manner that it can be rotated in both direction.

  • Patent number: 5488445
    Abstract: Standard film packages and telephoto-type film packages and panoramic film packages are produced using the same standardized package bodies which are adapted to photograph full-size frames on 35-mm film. In the factory, each package body is loaded with a photographic film, and indicia of the type of the film package to be produced are provided on the photographic film or a cassette for containing the photographic film, as well as on the film package. When printing a photographic film having been loaded into such a standard film package, substantially the whole area of the full-size frame is printed to make a standard print, whereas printing of photographic films that have been loaded into the telephoto-type film package and the panoramic-type film package is performed such that only a partial area of the full-size frame is printed at different print magnifications which are larger than that used for standard prints.

  • Patent number: 5471265
    Abstract: In a camera, one of a plurality of predetermined print aspect ratios is selected for each scene by manual operation of a print mode selection switch, and mechanically readable data representing the print aspect ratio is thereby recorded on the photographic film for each original frame during photographing. The original frames are recorded at a constant taking aspect ratio in the same size on the photographic film. During printing, the trimming data is read from the photographic film, and a part of the original frame that excludes both lateral sides of the original frame is printed based on the trimming data, so as to make a photographic print having the selected print aspect ratio. The camera is provided with a device for changing the field of view, that cooperates with the print mode selection switch, so as to change the aspect ratio of the field of view in accordance with the selected aspect ratio.

  • Patent number: 5174519
    Abstract: In a film cassette, a spool having a roll of film wound on it is rotatable within a cassette body, but the film leader of this film does not protrude from the cassette body. The roll of film is held between a pair of flanges of the spool or the film roll is pressed by a projecting member and a resilient member disposed on the inner wall of the cassette body. Thus the roll of film, when the spool is rotated, is also rotated together with it. As a result, the film leader is fed outside the cassette. In order to prevent light from entering the cassette from the film withdrawing slot, the film withdrawing slot is closed by a cover member and a mask. Also, by virture of a provision of a film passage extending within the cassette in a curved state or by mounting a projecting portion on the film leader, the interior of the cassette is masked.

  • Patent number: 5083155
    Abstract: A developed photographic film is contained in a cartridge such that the leader end of the photographic film does not protrude from the cartridge, the film being wound on a spool. In one embodiment, the cartridge has a notch formed in the side of a port portion. The photographic film is pushed out of the cartridge by a sprocket accessed to this notch when extra prints are made. In another embodiment, two roll chambers are connected with each other through a bridge portion having an aperture for exposing a picture frame. A further embodiment includes a splice tape connected at one end to the spool, the photographic film being connected to the spool through this splice tape. These respective embodiments can also be used as a container for containing an unexposed photographic film.

  • Patent number: 4174163
    Abstract: A film unit processing means in an auto-process camera, comprising first and second processing rolls or bars, and a frame to support said rolls or bars. In supporting said rolls, bars, or a combination, one above the other by the frame to define a passage therebetween for movement of the film unit therethrough, they are relatively inclined to cross at their centers at a predetermined angle to the plane perpendicular to the plane of advance of the film unit to provide an optimum pressure to process the film unit.
