    Abstract: There is disclosed a flexible mounting structure, rigidly supported at only two locations, for providing opposed precision motion of at least two mounting surfaces oppositely disposed upon the mounting structure in response to a force coupled symmetrically applied to the mounting structure. A pair of resilient connecting members, each having one of the two locations for support, and a pair of rigid mounting rails, each rail having at least one of the mounting surfaces disposed thereon, are connected to form a parallelogram whereby the mounting surfaces are substantially parallel. A rotatable shaft is disposed at right angles and adjacent to the rigid mounting rails. A drive tape is connected between the rotatable shaft and each of the rigid mounting rails in such a manner that as the shaft is rotated, each drive tape wraps around the shaft to provide the symmetrical force couple which moves the mounting rails. A cam follower arm is attached to the rotatable shaft and a cam roller bearing attached to the arm rides on a rotatable cam. Optical elements attached to the mounting surfaces transverse a precision path in accordance with the motion of the mounting rails.

    Abstract translation: 公开了一种刚性支撑在仅两个位置处的柔性安装结构，用于响应于对称地施加到安装结构上的力而提供相对设置在安装结构上的至少两个安装表面的相对精密运动。 一对弹性连接构件，每个具有用于支撑的两个位置中的一个，以及一对刚性安装轨道，每个轨道具有设置在其上的至少一个安装表面，以形成平行四边形，由此安装表面基本上 平行。 可旋转的轴以直角设置并与刚性安装轨道相邻。 驱动带以这样的方式连接在可旋转轴和每个刚性安装轨道之间，即当轴旋转时，每个驱动带都绕着轴缠绕以提供移动安装轨的对称的力对。 凸轮从动臂连接到可旋转轴上，并且连接到臂的凸轮滚子轴承骑在可旋转的凸轮上。 根据安装导轨的运动，附接到安装表面的光学元件横向于精密路径。
