  • Patent number: 6863454
    Abstract: A combination of a camera body with a lens, shutter and shutter operating control with an attachable, removeable film cartridge having an unexposed film spool region and an exposed film spool region and a bridging portion between those regions. An opening in the cartridge permits light from the lens to pass through the opening to the film at the bridging portion. A door closes the opening of the cartridge and the door is openable with the cartridge installed in or attached to the camera body. Cooperating elements on the camera body and the cartridge open the door or close the door with the door being openable when the cartridge is fully engaged with the camera body. There is a detented connection of the film cartridge in the camera body.

  • Patent number: 6542699
    Abstract: A camera is provided with an object lens, an aperture and a guiding device for an image-recording medium. The camera includes a device for providing generally scattered or white light to be incident on a first portion of the image-recording medium and a light adjusting device for varying the dissipation of the white or scatted light across the aperture of the camera in relation to the exposure time across the aperture. The camera also includes a lens system with an object lens and an additional focusing device with a focal length in a first area being infinite and in a second area being a relatively short focusing light on the image close to the lens system, for example, on the plate held in front of the lens system. A light enhancement device is also provided for increasing the light on the first portion of the image-recording medium.
