摘要： A web of copying material is transported on-edge through an exposure-station web guidance system provided with a masking system which includes stationary and shiftable transverse-edge framing plates. The projected image of a first longitudinal-edge reference line on the copy table supporting the original is brought into register with a corresponding reference line of the masking system. The projection scale is adjusted to cause the format-breadth of the projected image to be at most slightly smaller than the format breadth of the web, but in no event greater. The projected image of the first transverse edge of the original is brought into register with the edge of the stationary framing plate, and then that of the second transverse edge with that of the shiftable framing plate. This registration is effected by sensing infrared-light images of the dark-light transitions associated with the transverse edges of the original. An exposure is performed. Before transporting the exposed section of web out of the exposure station, a cutting mark is provided by a perforator on the shiftable framing plate, and this cutting mark is thereafter detected by a detector on the stationary framing plate and triggers a severing operation.

摘要： A xerographic copier machine capable of producing copies of an original document in a selectable magnification ratio. The machine includes an object mirror and a light source forming a scanning assembly which travels at a uniform velocity under a transparent platen on which the document to be copied is placed, face down. The object mirror reflects the illuminated image of the document toward a relay mirror moving in the same direction but at half the scan velocity, the relay mirror directing the image toward a stationary projection lens, behind which is a reflex mirror. The reflex mirror re-directs the image through the lens onto an image mirror which casts the image onto the photoreceptor surface of a rotating drum. The peripheral velocity of the drum is synchronized with the scan velocity of the scan assembly by an adjustable transmission whereby a latent image of the entire document is formed in the photoreceptor surface. In order to selectively change the magnification ratio, a retractable auxiliary lens is placed in front of the projection lens to alter the focal length of the optics, and the position of the image mirror relative to the drum is shifted to bring the image in focus on the photoreceptor surface. The synchronization transmission is adjusted to change the scan velocity of the assembly to a value appropriate to the selected magnification ratio.
摘要翻译：能够以可选择的放大倍率产生原稿的复印件的静电复印机。机器包括形成扫描组件的物镜和光源，扫描组件在待复印的文件放置在其下的透明压板下以均匀的速度行进。对象镜将文档的照明图像反射向在相同方向上移动但以扫描速度的一半移动的中继镜，继电镜将图像朝向固定投影透镜定向，其后面是反射镜。反射镜将图像通过镜头重新引导到将镜像投影到旋转鼓的感光体表面上的图像镜上。鼓的圆周速度与扫描组件的扫描速度同步，通过可调整的传动，从而整个文件的潜像形成在感光体表面中。为了选择性地改变放大率，将可伸缩的辅助透镜放置在投影透镜的前面以改变光学元件的焦距，并且相对于鼓的图像镜的位置被移动以使图像被聚焦感光体表面。调整同步传输以将组件的扫描速度改变为适合于所选择的倍率的值。

摘要： A multi-mode reproducing apparatus which includes means for copying documents selectively at a plurality of copy image magnifications. An imaging surface is arranged for movement at a given velocity. Optical elements are provided for viewing a document and for projecting an image thereof onto the moving imaging surface. The optical elements include a first stationary lens for projecting the image onto the surface at a first projected image magnification, and a second lens arranged for movement between a first stored position where it is inoperative and a second position where it is operative to project an image of the document onto the surface at a second projected image magnification different from the first magnification.

摘要： A reproduction camera has a carrier for a replaceable objective lens and a carrier for the image plane, both carriers being movable to different distances from a copy holder by electric motors, and an electronic digital computer, which determines the actual distances of the carriers from the holder by counting electrical pulses generated upon incremental movements of the carriers (as by pole passages of the motors, or directly); the desired distances for sharp focus, corrected for T (distance of the objective lens from the objective carrier) and HH'' (distance between principal focal points) are computed on the basis of the desired magnification and the focal length of the selected lens, and are compared with the actual distances; and the motors are controlled as the results of the comparisons of the actual and the desired distances.

摘要： AN AUTOMATIC COPYING MACHINE OPERABLE BETWEEN A REDUCED COPYING MODE AND A FULL SIZE COPYING MODE. IT HAS A TURRET LENS ASSEMBLY MOVABLE BETWEEN DIFFERENT POSITIONS FOR PROJECTING A FULL SIZE OR A REDUCED SIZE IMAGE OF AN ORIGINAL ONTO A COPY SHEET, AND A DRIVE SYSTEM FOR MOVING THE ORIGINAL AND COPY SHEET RESPECTIVELY PAST ILLUMINATING AND EXPOSURE STATIONS AT EQUAL OR UNEQUAL SPEEDS. A RESILIENT OVERTRAVEL OPERATING ASSEMBLY MOVES THE LENS ASSEMBLY BETWEEN POSITIONS AND FIRMLY HOLDS IT IN PLACE. IN THE FULL SIZE COPYING MODE THE COPY SHEET AND ORIGINAL MOVE AT THE SAME SPEED, IN THE REDUCED COPYING MODE THE ORIGINAL MOVES FASTER THAN THE COPY SHEET AND IN PROPORTION TO THE SIZE OF THE REDUCED LIGHT IMAGE. A SINGLE SWITCH CONTROLS THE COPYING MODE. DURING THE REDUCED COPYING MODE, IT TURNS ON EDGE EXPOSURE LAMPS WHICH DISCHARGE UNEXPOSED MARGINAL AREAS WHICH WOULD OTHERWISE FORM DIRTY COPY SHEET EDGES.
