  • Publication number: 20030142418
    Abstract: A lens-holding frame comprises a frame body and a plurality of elastically deformable lens-holding arms. The arms are supported in a cantilever manner by the frame body and they circumscribe a circle having the same diameter as the lens. A positioning member is provided on the frame body along the circumference of the circle so that the positioning member abuts against the circumferential edge of the lens to define the lens holding position. Each arm is provided with a projection that penetrates inside the circle. The projection has a tapered surface, so that when the circumferential edge of the lens is engaged with the projections and the lens is pushed in toward the positioning member, the arms are elastically pushed open and the circumferential edge of the lens rides over the projections, whereby the lens is held.

  • Patent number: 6600607
    Abstract: An zooming adjustment mechanism for an optical system is provided for reducing the length of the optical system along its optical axis, and enable the size down of the optical system. A cam ring is provided for adjusting distances between a first lens and a second lens that are constituting a telescope optical system in a binocular. Each of a first cam groove and a second cam groove includes two grooves. Two first cam grooves and two second cam grooves are formed on an outer circumferential surface at a distance along the circumferential direction. The two first cam grooves and the two second cam grooves are formed on the same area of the circumferential direction about the axis of the cam ring, i.e., the axis of a main shaft direction.

  • Publication number: 20030063382
    Abstract: In an optical viewer instrument with a photographing function, there is provided a telescopic lens system for observing objects, and a digital camera system including a solid-state image sensor and a photographing lens system associated with each other such that an object is formed as a photographed image on the solid-state image sensor through the photographing lens system. A manually-operable focussing mechanism is associated with the telescopic lens system and the photographing lens system such that the object is brought into focus through the telescopic lens system, and such that the object is brought into focus through the photographing lens system. Optical parameters are selected such that predetermined conditions are fulfilled, whereby the focussing of the telescopic lens system and the focusing of the photographing lens system can be suitably and properly performed by the focussing mechanism.

  • Publication number: 20030063189
    Abstract: In an optical viewer instrument with a photographing function, a telescopic lens system for observing an object and a digital camera system for photographing the object are housed in a casing. A manually-operable rotary wheel is rotatably provided in the casing such that a portion of the rotary wheel is exposed to the outside from the casing to bring the object into focus through the telescopic lens system. A display panel unit for displaying the object as a motion picture on a display screen thereof is mounted on the casing so as to be movable between a retracted position, where the display screen of the display panel unit is close to a wall surface of the casing, and a display position, where the display screen of the display panel unit is directed to the ocular-lens-system side of the telescopic lens system. The rotary wheel is arranged such that the exposed portion of the manually-operable rotary wheel is hidden behind the display panel unit when being at the retracted position.
