摘要： A zoom lens includes a cam barrel having bottomed cam grooves formed on an inner peripheral surface thereof, a lens frame guided in an optical axis direction, cam followers, and resilient supports which are resiliently deformable radially. Each bottomed cam groove includes a zoom section, and an accommodation section. Each bottomed cam groove is formed so that a depth of the accommodation section is greater than the zoom section. The resilient bias of each resilient support causes the cam followers to be biased against the bottomed cam grooves wherein the follower pins are fitted in the bottomed cam grooves so that no play occurs when the bottomed cam grooves are in the zoom section. Each resilient support is free from being elastically deformed so that the cam followers are inserted in the bottomed cam grooves with a predetermined amount of play when the bottomed cam grooves are positioned in the accommodation section.
摘要翻译： 变焦透镜包括具有形成在其内周表面上的底部凸轮槽的凸轮筒，沿光轴方向引导的透镜框，凸轮从动件和可径向弹性变形的弹性支撑件。 每个有底凸轮槽包括变焦部分和容纳部分。 每个有底凸轮槽形成为使得容纳部分的深度大于变焦部分。 每个弹性支撑件的弹性偏置导致凸轮从动件偏压到有底的凸轮槽，其中从动销装配在有底的凸轮槽中，使得当有底凸轮槽位于变焦部分时不会发生游隙。 每个弹性支撑件都不会发生弹性变形，使得当有底凸轮槽位于容纳部分中时，凸轮从动件以预定量的游隙插入有底凸轮槽中。

摘要： A lens frame guiding mechanism of a zoom lens includes lens frames having projections which extend radially outwards, wherein a cam follower is formed on each projection; a linear guide barrel; linear guide slots formed on the linear guide barrel parallel to the optical axis, wherein the projections of each lens frame are respectively engaged in the linear guide slots to be slidable therealong; a cam barrel fitted outside the linear guide barrel to be relatively rotatable about the optical axis thereto; and bottomed cam grooves formed on an inner peripheral surface of the cam barrel, in which the cam followers of a corresponding lens frame are respectively engaged. The lens frames are moved in the direction of the optical axis, without rotating about the optical axis, to change a focal length of said zoom lens via rotation of said cam barrel.

摘要： A zoom lens assembling mechanism includes a stationary barrel; a movable barrel; a linear guide barrel; a linear guide mechanism for linearly guiding the linear guide barrel; and at least one lens group which is linearly guided by the linear guide barrel. When the movable barrel is in an operating range, the linear guide barrel is linearly guided via the linear guide mechanism, while the movable barrel moves with the linear guide barrel while relatively rotating, to move the lens group. If the movable barrel is moved forward from a frontmost position of the operating range in order to disassemble an assembly including the movable barrel and the linear guide barrel from the stationary barrel, the linear guide barrel is no longer guided by the linear guide mechanism, and the linear guide barrel moves forward while rotating with the movable barrel to thereby remove the assembly.
