    • A lens barrel having an image blur prevention system including an image blur prevention optical system to prevent image blur, and an image blur prevention optical system drive mechanism to move the image blur prevention optical system within a plane that is generally perpendicular to the optical axis of a main optical system. The image blur prevention optical system drive mechanism is arranged around the image blur prevention optical system to most efficiently use the space in the lens barrel. A power transfer shaft, which is connected to a focusing system in the lens barrel, is arranged in parallel to the image blur prevention optical system, and the focusing system is located in front of the image blur prevention optical system so that it does not interfere with the image blur prevention optical system drive mechanism arranged around the image blur prevention optical system. By efficiently using the space in the lens barrel, the assembly and disassembly of the lens barrel is simplified. Further, by preserving space for the image blur prevention optical system, a large lens size may be maintained.
    • 一种具有防止图像模糊的图像模糊防止系统的图像模糊防止系统的镜筒,以及防止图像模糊防止光学系统的驱动机构,其将图像模糊防止光学系统移动到大致垂直于 主要的光学系统。 图像防止光学系统驱动机构设置在图像模糊防止光学系统周围,以最有效地使用镜筒中的空间。 连接到镜筒中的聚焦系统的传送轴与图像防止光学系统平行地布置,并且聚焦系统位于图像防止光学系统的前面,使得其不会干扰 其中图像防止光学系统驱动机构设置在图像防止光学系统周围。 通过有效地使用镜筒中的空间,可以简化镜筒的组装和拆卸。 此外,通过保留图像模糊防止光学系统的空间,可以保持大的透镜尺寸。

    • A lens barrel having a first moving barrel, second moving barrel, and a third moving barrel. The first moving barrel has first cam grooves configured corresponding to a focusing operation and holds an optical system used in a focusing operation. The second moving barrel has second cam grooves and is provided in relation to the first moving barrel. The third moving barrel has third cam grooves configured corresponding to a zoom operation and can move relative to a fixed barrel. The second cam grooves correct a position of said optical system corresponding to a drive operation of the third cam grooves.
    • 镜筒具有第一移动镜筒,第二移动镜筒和第三移动镜筒。 第一移动筒具有对应于聚焦操作配置的第一凸轮槽,并且保持用于聚焦操作的光学系统。 第二移动筒具有第二凸轮槽,并且相对于第一移动筒设置。 第三移动筒具有对应于变焦操作构造的第三凸轮槽,并且可相对于固定筒移动。 第二凸轮槽对应于第三凸轮槽的驱动操作校正所述光学系统的位置。
