摘要： A lens barrel including a telescopic cylinder accommodated within a fixed cylinder, and lenses retained in the telescopic cylinder. The lens barrel includes lens retaining frames to retain at least one of the lenses and a lens driving device to drive the lens retaining frames so as to drive the lenses along a longitudinal axis of the telescopic cylinder between a collapsed position in which one portion of the lenses is stored in the fixed cylinder and an extended position in which one portion of the lenses is extended out of the fixed cylinder toward a photographing subject. The lens barrel further includes a retractable lens that is retracted into the fixed cylinder through an opening in a wall of the fixed cylinder when the telescopic cylinder is in the extended position, and a retractable lens retaining frame to retain the retractable lens. The lens barrel includes an impact preventing member so that if the lenses are in the extended position and an external impact is received by the lens barrel, the impact preventing member abuts against one of the lens retaining frames to prevent the lens retaining frames from moving to the collapsed state and contacting the retractable lens retaining frame.
摘要翻译：包括容纳在固定筒内的伸缩筒的镜筒和保持在伸缩筒中的透镜。透镜镜筒包括透镜保持框架以保持至少一个透镜和透镜驱动装置来驱动透镜保持框架，以沿着伸缩筒的纵向轴线在折叠位置之间驱动透镜，其中一部分透镜被存储在固定圆筒中，并且延伸位置，其中透镜的一部分从固定圆柱体朝向拍摄对象延伸。透镜筒还包括可伸缩透镜，当可伸缩滚筒处于伸出位置时，缩回透镜通过固定圆柱体的壁中的开口缩回到固定圆筒中，以及可缩回透镜保持框架以保持可伸缩透镜。镜筒包括防撞构件，使得如果透镜处于伸出位置并且透镜镜筒接收到外部冲击，防撞构件抵靠透镜保持框架中的一个，以防透镜保持框架移动到折叠状态并接触可缩回透镜保持框架。

摘要： A lens barrel includes a telescopic cylinder, at least one movable lens, and a retractable lens. The telescopic cylinder includes at least one movable cylinder that can be accommodated in a fixed cylinder. The movable lens is retained in the movable cylinder. An optical axis of the movable lens determines a reference axis of the lens barrel. The retractable lens can be retracted in a plane perpendicular to the reference axis from a photographing position on the reference axis to a retracted position off the reference axis. In a photographing state, the retractable lens is adjacent to the movable lens, and the movable lens and the retractable lens are coaxially aligned along the reference axis. The retractable lens moves to the reference axis from the retracted position immediately after the movable cylinder of the movable lens reaches a maximum protruded position.
摘要翻译：透镜筒包括伸缩筒，至少一个可移动透镜和可伸缩透镜。伸缩筒包括可容纳在固定筒中的至少一个可动气缸。可移动透镜保持在可动圆筒中。可移动透镜的光轴决定镜筒的基准轴。可缩回透镜可以从垂直于参考轴线的平面从参考轴上的拍摄位置缩回到离基准轴的缩回位置。在拍摄状态下，可伸缩透镜与可移动透镜相邻，并且可移动透镜和可缩回透镜沿参考轴线同轴对准。可伸缩透镜在可移动透镜的可动圆筒的最大突出位置之后立即从缩回位置移动到参考轴。
