20110128634 | Lens Barrel, Camera and Information Device - A cam locus of the cam surface on the image plane side of the first group cam groove of the rotating cylinder has an angle to a flat surface where the optical axis crosses perpendicularly. When the cam follower engages with the cam surface on the image plane side, an impact force is dispersed into the optical axis direction and the rotating direction of the rotating cylinder, and a load on the cam follower and male helicoid is reduced. When the first group lens system is pressed by a light load, the cam follower of the first group lens movement frame engages with the cam surface on the image plane side, and an angle of the cam surface is equal to an angle of a force occurring in the rotating direction. Therefore, the rotating cylinder does not rotate easily, and returns to its previous position when the load is removed. | 06-02-2011 |
20120093495 | LENS BARREL - A lens barrel that reinforces a connecting part between a movable lens barrel and a fixed barrel, without requiring a new drive source, is disclosed. The lens barrel includes: a rotary barrel fitted in a fixed barrel; a cam mechanism for connecting the rotary barrel and the fixed barrel; and a ring member. The fixed barrel includes an engagement section and a rotary drive mechanism for revolving the ring member. The rotary drive mechanism locates the ring member to an engagement-enabling position when a connection by the cam mechanism reaches a predetermined position, directing the connection from a first end to a second end of an idle revolving area, the first end continuing to an advancement/retreat movement area; and to a release position, when the connection by the cam mechanism is located at the first end of the idle revolving area. | 04-19-2012 |
20130088791 | LENS BARREL - A lens barrel includes a plurality of lens groups including a retractable lens group, a plurality of lens retaining frames to respectively retain the plurality of lens groups, a movable lens barrel to retain the plurality of lens retaining frames therein, and a lens retaining frame driving device to drive the lens retaining frames via the movable lens barrel. The lens retaining frames, the movable lens barrel and the lens retaining frame driving device move the plurality of lens groups between a collapsed state and a photographing state. The plurality of lens retaining frames includes a retractable lens retaining frame to movably retain the retractable lens group so as to position the plurality of lens groups on a photographing axis in the photographing state and to retract the retractable lens group to a housing located outside an inside diameter position of the movable lens barrel in the collapsed state. The retractable lens retaining frame is movable between a position on the photographing axis and a position inside the housing at least by moving in a direction inclined relative to the photographing axis and moving in a direction orthogonal to the photographing axis. | 04-11-2013 |
