  • Patent number: 6543614
    Abstract: A lens housing container for housing a plurality of lenses, comprising a long carrier tape having a supporting portion for supporting one ring-shaped surface of the flange portion of the lens, and a plurality of lens housing portions; and a long cover tape to be stuck on the carrier tape so as to cover the lens housed in the lens housing portion, wherein the supporting portion supports the one ring-shaped surface of the flange portion of the lens, so as not to come into contact with the one lens surface of the lens, the lens housing portion houses the lens so that a part of the other lens surface of the lens is projected from or is flush with the upper surface of the carrier tape, the cover tape restrains the lens housed in the lens housing portion from moving in the optical axis direction.

  • Patent number: 5079575
    Abstract: When a lens system is focussed at a fixed length, what range of an object is clearly photographed is determined by the focal length and F number of the lens. In order that a zoom lens which requires no focussing operation is mounted on the beginners' camera to make the focussing range as wide as possible, the focussing position need be deviated as the focal length f varies as zooming takes place. If F number is selected in the range of F.gtoreq.2.8.times.10.sup.-3 .times.f.sup.2, a performance camera can be realized with a zoom lens including a wide angle and having a variable power ratio of the order of 2.

  • Patent number: 4699489
    Abstract: A film winding member for a camera includes a lower disposed portion of widened diameter for initial contact with the leading end of the film. Both the widened diameter portion and the relatively narrower remainder of the film winding member present uninterruptedly smooth and continuous surfaces about which the film is operatively wound. The peripheral surface of the film winding member is formed of a material having a coefficient of sliding friction or at least 1.5, and preferably of silicone rubber having such a coefficient of sliding friction.
