  • Zoom lens barrel
    Patent number: 8422156
    Abstract: A zoom lens barrel includes a fixed frame, a rotary frame, a moving frame that moves in an optical axis direction with the rotary frame, a float key that is restricted from rotating and moves, an inner cam frame that has a cam follower, is rotationally driven by the rotary frame, and moves in the optical axis direction, a guide frame that has a cam follower, and moves in the optical axis direction, an outer cam frame moves in the optical axis direction with the guide frame, and moves relatively with respect to the guide frame, a second group zoom frame that holds a second group lens, has a cam follower, is restricted from rotating around the optical axis, and moves in the optical axis direction, and a first group zoom frame that holds a first group lens, has a cam follower, and moves in the optical axis direction.

  • Lens barrel
    Patent number: 7372638
    Abstract: There is disclosed a lens barrel including a fixed frame, a rotary frame rotatable with respect to the fixed frame to advance or retract in an optical axis direction, and a rectilinear guide frame rotatable relative to the rotary frame to displace integrally with the rotary frame in the optical axis direction. In this structure, a front end portion of the rectilinear guide frame on a subject side in the optical axis direction is exposed from the rotary frame.
