    • An optical mounting apparatus (10) comprises an upper support assembly (12) and a lower post assembly (14). The upper support assembly (12) includes a stage plate (21) mounted on a backing plate or baseplate (22) by a three point suspension mechanism. By locating an optical element mounting region (16) at the corner of a rectangle defined by the three suspension points, a datum point (60) within the region (16) can be rotationally adjusted without simultaneous translational adjustment by manipulating only two of the three suspension points. The baseplate (22) is mounted on a support rod (94) which is slidably received in a casing (70). A lever arm (80) having a surface (98) which engages the support rod (94) can be moved relative to the casing (70) for selectively locking the rod (94) in place.
    • 光学安装装置包括上支架和下支架。 上支撑件包括通过三点悬挂机构安装在支撑板上的上板。 将光学元件安装区域放置在由三个悬挂点限定的矩形的拐角处允许在没有同时平移调节的区域中的参考点通过仅通过操纵两个 三点暂停。 所述基板安装在可滑动地容纳在壳体中的支撑杆上。 具有与支撑杆接合的表面的杠杆臂可相对于壳体移动以选择性地将杆锁定在适当位置。

    • A clear, transparent, rigid plastic sheet is bent into an inverted U-shape to provide a top (40) supported by continuously transparent legs (42, 44). A fresnel lens (50), co-extensive with the top, is secured to the top or actually formed in one of its surfaces to provide a hand-free, self-supporting large area magnifier capable of use in reading a complete printed page with little or no shifting of the magnifier. For various scientific and other purposes, scales, grids, or other reference marks (62) or patterns are carried on transparent elements secured to the bottoms of the legs where they are likewise magnified for counting or measuring or other large area analysis, or study of a full page or document being read.

    • A lens mounting for enabling rapid changes of lenses wherein a lens carrying structure (48) is arranged to be detachably secured to an apertured support structure (25, 30) by virtue of lugs (50) provided on the lens carrying structure (48) engaging between a planar, annular, spring element (32) and a rigid portion or portions (54) of the support structure (25, 30). Owing to the resilience of at least a portion (56) of the spring element (32), the latter biases the lugs (50) against said rigid portions (54), thereby securing the two structures together. In the preferred embodiment, the rigid portions (54) are inwardly extending lugs of a mounting plate (30) engaging with outwardly extending lugs (50) of the lens carrying structure (48). In another embodiment, the spring element (32) and mounting plate (30) are secured to the lens carrying structure (48) and the outwardly extending lugs are provided on the support structure (25).
    • 一种透镜安装件,用于实现透镜的快速变换,其中透镜承载结构(48)被布置成通过设置在透镜承载结构(48)上的凸耳(50)可拆卸地固定到有孔支撑结构(25,30)上, 在平面的,环形的弹簧元件(32)和支撑结构(25,30)的刚性部分或部分(54)之间。 由于弹簧元件(32)的至少一部分(56)的弹性,后者将凸耳(50)偏压抵靠所述刚性部分(54),从而将两个结构固定在一起。 在优选实施例中,刚性部分(54)是与透镜承载结构(48)的向外延伸的凸耳(50)接合的安装板(30)的向内延伸的凸耳。 在另一个实施例中,弹簧元件(32)和安装板(30)固定到透镜承载结构(48),并且向外延伸的凸耳设置在支撑结构(25)上。

    • A camera with two object lenses, one of which is selectively set in a photographing position and the other in a shunting position, has a film positioning surface (4) and two other guiding surfaces (5, 6) with which the end parts of object lenses (2, 3) are in contact in their respective positions along an optical axis. These three surfaces (4, 5, 6) form one unit, while a cavity capable of receiving one of the object lenses (3) is provided between the two surfaces (5, 6). Each of the object lenses (2, 3) is pressed onto the guiding surface (5, 6) by spring means (7, 8) in the photographing position.
