  • Patent number: 5930543
    Abstract: An aperture selection mechanism for camera lens includes an aperture strip and a disk selection knob. The aperture strip has two or more different sizes of apertures equally spaced from each other and being sequenced by size. Turning the selection knob, the aperture strip will be moved and one of the apertures will be positioned in the light path of the camera lens. Two or more apertures may be moved to the light path of camera lens one at a time so that the camera can produce better quality of photo and image. The structure is simple, low cost and easy to use.

  • Patent number: 5930544
    Abstract: A lens movement mechanism for digital camera includes a lens set which has a composite lens and a Charged Couple Device built therein, a first movement member for turning the lens set angularly left or right, and a second movement member for turning the lens set angularly up or down. The first movement member includes a bracket piovtly holding the lens set and a gear set for turning the bracket and the lens set left or right angularly. The second movement member includes a slant block with a slope surface contact with a rear end of the lens set so that when the slant block is moved transversely, the lens set will be tilted up or down angularly. Therefore the lens set may be turned left or right, up or down smoothly and precisely without a user's hand moving the lens set directly. The lens may be prevented from hand smearing. Higher photo quality may be achieved.

  • Patent number: 5907730
    Abstract: A moveable lens apparatus for digital camera includes a CCD lens set, a first motion mechanism having a bracket pivotally holding the lens set and a first gear set for driving the bracket and the lens set to rotate left or right angularly, and a second motion mechanism having a guide slidably engageable with a rear end of the lens set, a gear rack vertically attached to the guide and a second gear set for driving the gear rack and the guide up or down so that the lens set may be swung pivotally up or down. The first and second gear set may be actuated manually or by motors. The lens set thus may be moved and rotated smoothly and precisely without a user's hand directly touching the lens set.

  • Patent number: 5815759
    Abstract: An extended adjusting mechanism for the lens set of an imaging system, which utilizes motion connection means between the main body and the lens set of the imaging system to enlarge the view scope of the imaging system, comprises the lens set for viewing and recording and a connection carrier located at one side of the main body. The connection carrier, which is a carrier for the lens set, further comprises a base connected rotationally to the main body and a dumb-bell connection as a motion junction means between the base and the lens set.
