  • Patent number: 5721610
    Abstract: A film image pickup device uses a cartridge in which film is fed out of the cartridge by causing a spool around which the film is wound to rotate. The film image pickup device includes a drive roller and a driven roller that are located near the film outlet of the cartridge and that are used for the conveyance of the film. The drive roller and driven roller are constructed such that either roller can come into contact with or retract from the other roller. Either of the drive roller and the driven roller has a barrel-shaped cross-sectional configuration while the other has a bobbin-shaped cross-sectional configuration, to impart a curvature to the film as it is pulled out of the cartridge.

  • Patent number: 5677759
    Abstract: The present invention is a film housing device comprising a film housing member that houses developed film; a driving mechanism that feeds the film housed in said housing member to a position outside the housing member where the film may be visually observed by the naked eye; and an operating member to operate said drive mechanism. Using said construction, when the operating member of the film housing device is operated, the drive mechanism operates and the developed film is fed to a position outside the housing member where the film may be visually observed by the naked eye. Therefore, the photographic content of the film may be confirmed with the naked eye using only the film housing device where it is not necessary to connect the device to a film reading device such as film scanner.

  • Patent number: 5056903
    Abstract: A lens barrel for a waterproof or dustproof camera which can assure maintenance of a reliable liquid-tight or airtight condition between a movable lens barrel member and a fixed lens barrel member with a structure of a comparatively small size. The lens barrel comprises a fixed lens barrel member provided on a camera body, a movable lens barrel member mounted for movement on the fixed member between a position advanced outwardly from the camera body and another position retracted in the camera body, and a bellows member secured at an end thereof to an inner periphery of a rear portion of the movable member and at the other thereof to an inner periphery of a rear portion of the fixed member. The bellows member is folded back at an intermediate portion thereof between the movable member and the fixed member in such a manner as to surround a rear end of the movable member, and the folded back portion moves as the movable member is moved between the retracted position and the advanced position.
