摘要： An electrophotographic copying machine has a flash lamp for applying a flash of light to a document to be copied. The copying machine also includes a sensor for detecting whether the flash lamp is energized or not. When there is no signal indicating that the flash lamp is energized even in the presence of a command to energize the flash lamp, a control circuit determines that the flash lamp has failed to emit light at a predetermined exposure timing, and produces an output signal to effect a predetermined operation upon non-energization of the flash lamp. An arrangement for effecting such a predetermined operation may for example be a switch of an erase lamp, a control circuit for controlling operation of a copy counter, a switch of a motor for driving image developing rollers, a control circuit for controlling a developing bias, a switch of an image transfer charger, a control circuit for controlling a separator finger for changing feed paths of travel of an image transfer sheet, a control circuit for controlling a shutter to cover an image transfer charger, or a switch for driving rollers which feed an image transfer sheet.

摘要： A movable document handling system, or module, is utilized on a modified standard office copier. When the document handling module is moved away from the platen glass area, the document handling module equipment is disabled and the office copier may be used as a standard copier. When, however, the document handling module is moved over the platen glass, other optics and document handling apparatus are now energized and the standard office copier is now converted into a large document copier. A fold mirror in a first position directs reflected light from the large input document through the standard platen glass for 100% size copying. The fold mirror can be repositioned to reflect the reflected light toward a reduction mirror assembly which then directs the light through the standard platen glass for reduced size copying. The reduction mirror assembly is capable of being repositioned to provide various predetermined amounts of optical reduction.
摘要翻译：可移动文件处理系统或模块被用于经修改的标准办公复印机。当文件处理模块远离稿台玻璃区域时，文档处理模块设备被禁用，办公室复印机可以用作标准复印机。然而，当文件处理模块移动到稿台玻璃上时，其他光学元件和文件处理装置现在被通电，并且标准办公复印机现在被转换成大型文件复印机。第一位置的折叠反射镜通过标准稿台玻璃引导来自大输入文档的反射光，以进行100％的复印。折叠镜可以重新定位以将反射光反射到还原反射镜组件，然后引导光通过标准稿台玻璃以减小尺寸复印。还原反射镜组件能够重新定位以提供各种预定量的光学还原。

摘要： An image forming apparatus is disclosed that provides dual-page copies of a document that are free of offset. The apparatus includes a fixed scale that provides a scanning start position for the first page of the document, and a movable scale that provides a scanning end position for the second page of the document. The document is placed on a document table with a first edge of the document positioned with respect to the fixed scale. An operator controls the positioning of the movable scale to indicate the second edge of the document. The copy operation is controlled based on a prescribed range for the pages of the document that is defined by the position of the fixed and movable scales.

摘要： When directing a slit-like image information light to an imaging lens through a condensing lens, the refractive power of the condensing lens is made to differ between the lengthwise direction and the slit width direction of the slit light beam, whereby the light is effectively received without the read image being deteriorated. Also, when a convergent light transmitting member array is used as the imaging lens, the refractive power of the condensing lens is made to differ between the lengthwise direction of the array and a direction orthogonal to the lengthwise direction of the array, whereby the light is effectively received without the read image being deteriorated.

摘要： In an electrophotographic copier, adjustments are made to synchronize copy sheet gating optics start of scan, and document conveyor registration. The adjustment to the copy sheet gating is effected by making a copy with the optics assembly inactivated, determining the length of undeveloped area adjacent to the leading or trailing edge of the copy, and adjusting the start of scan as a function of the determined length. The start of scan of the optics assembly is effected by positioning a test master document with dark portions adjacent to its leading and trailing edges, making a copy of the test master document, determining the length of undeveloped area adjacent to the leading or trailing edge of the copy, and adjusting the start of scan as a function of the determined length. The adjustment of the document conveyor registration is effected by feeding the test master document to the document glass, making a copy of the test master document, determining the length of undeveloped area adjacent to the leading or trailing edge of the copy, and adjusting the document conveyor as a function of the determined length. The determining steps may be done by visual inspection or by an optical sensor. The adjusting may be done manually, either electronically or mechanically. In the alternative, the adjusting may be done automatically in response to the optical sensor.

摘要： A photocopying device which is to be attached to a conventional photocopying machine, gives to the machine the capability of copying from bound books. The device has a V-shaped book rest for supporting a book in an open condition and a scanning head with a light source. The device can be mounted on a photocopying machine so that light from the scanning head is reflected from a page of the book back to the drum of the photocopying machine, along the same route as is taken by light travelling to the drum during conventional operation, without the device.

摘要： The present invention is directed towards an optical scanning system for an electrophotograhic printing machine wherein a lens control system is provided to enable lens movement independent of lens movement which occurs during magnification changes. The lens carriage is adapted to be independently driven in one or two directions dependent on the mode of operation selected by the operator and under the control of a system controller which analyzes the inputs which determine lens position (open platen or document feeder mode, output copy size, magnification).

摘要： A vacuum fluorescent lamp has a novel planar construction permitting it to be closely positioned to an object plane and hence, used as an efficient illuminator. The lamp is constructed so that the lamp surface interfacing the object plane is optically transparent so as to permit illumination to reach a scan illumination strip. The lamp surface opposite the interface surface has an optical window formed therein which permits light rays reflected from the document to exit the lamp along an optical path extending through the lamp.

摘要： Disclosed is a copying machine using the same unit for commonly executing exposure and cleaning, while providing a copy of the original by causing the photoconductor to rotate through two revolutions. The copying machine sequentially executes operations including uniformly charging a photoconductor during its first revolution, image exposure via an exposure unit, forming a electrostatic latent image on the photoconductor, making the electrostatic latent visible via a developer unit and subsequent transfer of the developed image onto a copy paper, and cleaning of the residual toner from the photoconductor using the same developer unit during the second revolution of the photoconductor.The copying machine executes image exposure using an image exposure unit during the first revolution of the photoconductor and also executes an optical discharge by commonly using the image exposure unit at the same position during the second revolution of the photoconductor.
