  • Patent number: 6868231
    Abstract: Methods and apparatii are provided that use a photosensitive element that is photosensitive to light within a predetermined range of exposure levels to capture images including exposure levels that are outside of the predetermined range of exposure levels. The photosensitive element is exposed to light from a scene. The light from the scene is fractured into concentrated and residual portions with the concentrated portions being directed to form a pattern of concentrated image elements on the photosensitive element when light from the scene is within a first exposure range with the residual portion of the light being directed to form a residual image when light from the scene is within a second exposure range. The light from the scene is adapted also so that the pattern of concentrated image elements is formed in a predefined pattern of concentrated image areas on the photosensitive element.

  • Patent number: 6603931
    Abstract: A camera incorporates a photo film support plate, which supports a back of photo film. The photo film has a magnetic recording area. An opening is formed in the photo film support plate. A magnetic head projects forwards from inside the opening, for recording information to and/or reading information from the magnetic recording area. A head base plate is mounted on a rear face of the photo film support plate to cover the opening, for supporting the magnetic head. Adhesive agent is applied to the periphery of the head base plate, and hardened for securing the head base plate to the photo film support plate. A pair of recesses are formed in a rear face of the head base plate in a vicinity of the periphery. The adhesive agent is disposed to extend from a front face of the head base plate to a surface of the recesses, which enlarge a contact area between the adhesive agent and the head base plate.

  • Patent number: 6522835
    Abstract: A lens-fitted photographic film package with dual lens includes a film-free self-activating shutter mechanism and a detachable cartridge for removing and installing film. A 35-mm film cartridge is attached to a cartridge adapter, and a filmstrip end is inserted and pre-wound into a winding housing including a winding spool therein. As photographs are taken, film is advanced frame-by-frame into the film cartridge, where it may be easily removed from the adapter without rewinding of the film, and replaced by a fresh film cartridge. Thus, the adapter transforms the lens-fitted photographic film package into a reusable package.

    Abstract: A partially assembled one-time-use camera includes a film section that longitudinally extends from a rotatable film winding spool in a film cartridge and that is engaged with a rotatable metering sprocket, and a separate rear cover part that is to be placed over the film section and the film cartridge and is constructed to prevent the film section from retracting out of engagement with the metering sprocket. The film winding spool is rotatable in a film winding direction to wind the film section into the film cartridge. If the film cartridge is allowed to rotate in the film winding direction before the rear cover is placed over the film section and the film cartridge, the film section will retract out of engagement with the metering sprocket. Consequently, a cartridge retention piece is positioned against the film cartridge to prevent the film cartridge from being rotated in the film winding direction.

    Abstract: A hybrid camera of the present invention selectively uses one of a photographic film and an image sensor, to record an object image. The hybrid camera has a photographing optical system, a body, and a film positioner. The film positioner is detachably mounted in the body and defines a position of an exposure area of the photographic film, along an optical axis of the photographing optical system. An accommodation space, which can accommodate the image sensor, is formed in the body by detaching the film positioner. When using the photographic film, the film positioner is mounted in the body such that the position of the exposure area coincides with a position of a focal plane, defined by the photographing optical system. Then, when using the image sensor, the film positioner is detached from the body and the image sensor is placed in the accommodation space, such that a position of a light-receiving area of the image sensor coincides with the position of the focal plane, along the optical axis.

    Abstract: A one-time-use camera comprises a filmstrip having a certain width and a film leader for the filmstrip having another width that is greater than the width of the filmstrip, a film-exposure backframe opening, a pair of parallel film edge guides located apart from each other a distance substantially equal to the width of the filmstrip to guide the filmstrip over the backframe opening, and a pair of leader edge guides located parallel to the film edge guides and apart from each other a distance less than the width of the wider leader, but greater than the distance separating the film edge guides, in order to make the wider leader be bent widthwise at opposite longitudinal edge portions of the wider leader between the film edge guides and the leader edge guides, whereby the wider leader is prevented from having to significantly increase the size of the one-time-use camera.

  • Patent number: 5970257
    Abstract: A camera frame assembly for use with photographic film. The camera frame assembly has a pair of path subenclosures. Each subenclosure has a platen subunit and an intermediate section subunit joined in fixed relation to the platen subunit. The path subenclosures are joined together with the platen subunits in alignment and the intermediate section subunits in alignment, such that the platen subunits form a platen for the photographic film and the intermediate section subunits form an intermediate section overlying the platen.

  • Patent number: 5940650
    Abstract: A windup reel is formed at a step reel which has a small diameter section and a large diameter section. The large diameter section is formed in such a direction as to press a lower edge of photographic film against a guide pin. When a leader section of transported photographic film is wound on the windup reel, the leader section tries to fit the surface of the large diameter section. For this reason, the force is applied to the photographic film so that the photographic film can move toward the large diameter section. The photographic film moves toward the guide pin, and the edge of the photographic film is pressed against the guide pin. Thereby, the photographic film is transported along the guide pin.

  • Patent number: 5937209
    Abstract: A camera comprising a main body part having a backframe opening for exposing successive sections of a filmstrip, a metering sprocket rotatably supported on the main body part proximate the backframe opening and having respective teeth that can project through individual perforations in the filmstrip to engage successive sections of the filmstrip at the backframe opening, and a rear cover part having a plurality of parallel film guide ribs longitudinally extending to guide successive sections of the filmstrip over the backframe opening, is characterized in that one of the film guide ribs includes an integral portion configured to at least partially surround the teeth of the metering sprocket one at a time, in a predetermined location at which each tooth projects from one of the perforations in the filmstrip, to retain a film section at the backframe opening in engagement with the tooth.

  • Patent number: 5897234
    Abstract: A film passage is formed at a rear side of an exposure aperture which is disposed between a cartridge chamber 11 and a film take-up chamber 12. The film passage comprises a passage channel 15 integrally formed with a camera main body and a film support plate covering a rear side of the passage channel. By covering the passage channel with the film support plate, an inside of the slit-like film passage is maintained in light-tight state before attaching the rear cover to the main body. A film take-up chamber cover is attached to the film take-up chamber to constitute a part of a wall thereof. By covering a rear side of the film take-up chamber with the film take-up chamber cover, the inside of the film take-up chamber is maintained in light-tight state before attaching the rear cover to the main body.
