Film Chamber Detail Patents (Class 396/538)
  • Patent number: 7929858
    Abstract: An image-capturing element that receives light of a subject image entering within a camera body through an interchangeable photographic lens is packaged and is mounted at the camera body via a holder. A camera-side mounting surface and a holder-side mounting surface are machined in advance and formed respectively relative to the mounting surface for the photographic lens formed at the camera body and the light-receiving surface of the image-capturing element. By mounting the image-capturing apparatus with the camera-side mounting surface and the holder-side mounting surface placed in contact with each other at the camera body using screws, the light-receiving surface is aligned with the image-forming position of the photographic lens.

  • Patent number: 7463822
    Abstract: A camera assembly includes an endcap assembly for closing off the bottom end of a second film chamber, which is sized to selectively receive a roll of film or a secondary film cartridge housing a roll of film. The endcap assembly can include a movable shutter blade enclosed between two plates. The endcap assembly can be removably secured to the camera assembly. At least a portion of the endcap assembly can be formed with the camera assembly. Embodiments further relate to a method of loading such cameras, especially in the daylight. The method involves bringing a sleeve into light-tight engagement with the endcap assembly and then inserting a winding rod through the sleeve and the endcap assembly and into a second film chamber of the camera. The winding rod can then be used to wind film out of a cassette in the first chamber and into a roll in the second chamber.

  • Patent number: 6512893
    Abstract: A camera of the kind using a cartridge with the cartridge accommodated inside a cartridge chamber is required to ensure that the lid of the cartridge chamber is openable only when film has been rewound into the cartridge. To meet this requirement, there is a known method for unlocking the cartridge chamber lid only when the film has been rewound. However, in the event of some accident, it might become impossible to rewind the film to make the cartridge chamber lid no longer unlockable. To solve this problem, a camera according to the invention disclosed is arranged to make the cartridge chamber lid unlockable in response to a specific operation performed differently from an ordinary photo-taking operation.

  • Patent number: 6507712
    Abstract: A camera in which a magazine can be loaded into a magazine chamber in the direction along a winding shaft thereof in a state in which a film leader is wound thereon. During such magazine loading, the film leader is inserted along the outer periphery of a film guide disposed in the magazine chamber. After the magazine has been loaded, the film leader is temporarily rewound into the magazine. Then, it is fed toward a spool chamber. The film leader that has reached the spool chamber is advanced by the spool and film loading is completed. By employing such a loading mechanism, it is possible to provide a camera incorporating a film loading mechanism with a simple structure which is capable of reliable film loading and making it possible, in cameras using 135-type film magazine, to load a magazine in the axial direction thereof.

  • Patent number: 6371666
    Abstract: A hook of a cartridge-chamber lid is engaged with one end of an engagement lever to be kept in a closed position. The other end of the engagement lever is engaged with an intermediate lever attached to an upper face of a cartridge chamber. When a photo film is wound up, a winding-up lock mechanism comprising an urging gear, a lever member and a winding-up lock member prevents the intermediate lever from rotating, namely prevents the engagement lever from swinging to lock the cartridge-chamber lid. When the photo film is rewound, a rewinding lock mechanism comprising an urging gear, a lever member, a rewinding lock member and a torsion spring prevents the intermediate lever from rotating, namely prevents the engagement lever from swinging to lock the cartridge-chamber lid.
