    • A microfilm camera is provided which has a camera head positioned above an exposure table. The exposure table included a pivotable glass plate and originals to be photographed can be placed beneath the glass plate or on its upper surface. To enable in-focus pictures of originals in either position to be taken, means are provided to vary the distance between the film in the camera head and the glass plate. In one embodiment the exposure table is mounted on four columns each having a lifting cam operated by a common activating handle. In a second embodiment the camera head can be raised or lowered by a handle operated eccentric cam.
    • 提供了一种缩微胶卷相机,其具有位于曝光台上方的相机头。 曝光台包括可枢转的玻璃板,可以将待拍摄的原件放置在玻璃板的下方或其上表面上。 为了使原件的对焦照片在任一位置被拍摄,提供了用于改变照相机头部中的胶片与玻璃板之间的距离的装置。 在一个实施例中,曝光台安装在四列上,每列具有由公共激活手柄操作的提升凸轮。 在第二实施例中,相机头可以由手柄操作的偏心凸轮升高或降低。

    • A focal-plane leaf shutter for photographic cameras, comprises an opening group of leaves and a closing group of leaves, each group having a main leaf which forms a parallelogram linkage with a pair of carrier levers, and secondary leaves. The main leaves serve to define an exposure aperture. The carrier levers are mounted by means of stationary pivot journals on a plate at one short side of the exposure aperture and the main leaves are pivotally connected by means of bearing journals to the free ends of the carrier levers. The secondary leaves are connected with the carrier levers at intervals between the pivot journals and the bearing journals. The two innermost carrier levers forming parallelogram linkages with the main leaves are mounted on a common pivot journal.
    • 一种用于照相机的焦平面叶片,包括叶片的开放组和叶片的封闭组,每组具有与一对载体杆和次叶形成平行四边形连杆的主叶。 主叶用于限定曝光孔径。 承载杆通过固定的枢转轴颈安装在曝光孔的一个短边处的板上,并且主叶片通过轴承轴颈枢转地连接到承载杆的自由端。 次级叶片与枢轴轴颈和轴承轴颈之间的间隔与承载杆连接。 形成与主叶的平行四边形连接的两个最内侧的载体杆安装在共同的枢轴轴颈上。

    • A microfilm camera has a carrier plate for holding a film sheet and a slidable carriage for sliding the carrier plate into and out of an operative position. The carrier plate is secured to the slidable carriage either directly or via a guide bush by means of three retaining screws which form the angles of a triangle which includes the geometric center of the carrier plate. Associated with each retaining screw is a support screw by means of which the distance between the carrier plate and the slidable carriage can be adjusted at each of the angles of the triangle. To enable the adjustment to be made by means of an auto-collimator, the carrier plate may be mirror-coated or the surface thereof which is intended to hold the film sheet.
    • 微缩胶卷相机具有用于保持胶卷片的承载板和用于将载板滑入和移出操作位置的滑动滑架。 承载板通过形成包括承载板的几何中心的三角形的角度的三个固定螺钉直接或经由引导衬套固定到滑动托架。 与每个固定螺钉相关联的是支撑螺钉,通过该支撑螺钉,可以在三角形的每个角度调节承载板和滑动托架之间的距离。 为了能够通过自动准直器进行调整,承载板可以是镜面涂覆的,或者是用于保持膜片的表面。

    • The micro-filming apparatus comprises an object table, a camera head arranged above said table, a frame pivotally mounted on said table, a glass plate and mounting therefor mounted on said frame, said glass plate being capable of movement perpendicularly of the plane of the frame to adjust the distance between the object and the film, setting sliders mounted on said frame movable between first and second positions, a handle attached to said sliders by which movement between said two positions is effected, and coacting means arranged between said sliders and the plate to effect perpendicular movement of said glass plate on movement of said sliders, wherein on movement of said sliders into the first position the lower surface of the glass plate is brought into the picture-taking plane and on movement into the second position the upper surface of the plate is brought into the picture-taking plane.In this manner vertical displacement of the camera head or object table is avoided which occasional photographing of single flat sheets of different thicknesses previously demanded.
    • 该微型成像设备包括一个对象台,一个设置在桌子上方的照相机头,一个可枢转地安装在桌子上的框架,一个安装在所述框架上的玻璃板和安装件,所述玻璃板能够垂直于 框架以调节物体和胶片之间的距离,设置安装在所述框架上的滑块可在第一和第二位置之间移动;附接到所述滑块的手柄,通过该滑块可实现所述两个位置之间的移动;以及联合装置,布置在所述滑块和 板以使所述玻璃板在所述滑块的运动上的垂直运动,其中当所述滑块移动到第一位置时,玻璃板的下表面被带入摄像平面并且在运动到第二位置时,上表面 的盘子被带入摄影机。 以这种方式,避免了相机头或物台的垂直位移,偶尔拍摄先前需要的不同厚度的单张平板。
