摘要： An improved electrophotographic copying apparatus is described, which permits, during automatic copying of a desired number of copies from the same original document, the setting of the number of repeated uses of the same latent electrostatic image, thus obviating the lowering and unevenness of image quality of the copies. In another embodiment of the improved electrophotographic copying apparatus, the timing of the formation of successive latent images of the same original document is controlled in accordance with the total number of copies to be made of the same original document so that the number of repeated uses of each respective latent image is made approximately equal. Also, in the latter embodiment, a signal indicating the timing for the exchange of successive original documents is generated at the time of formation of the last electrostatic image from the prior original document.

摘要： A variable magnification optical system focusses an image of a portion of an original document on a platen through a variable aperture or slit onto a rotating photoconductive drum. Various members of the optical system or the document are moved at a speed corresponding to the surface speed of the drum to scan the document and form an electrostatic image thereof on the drum. The slit is defined by a fixed aperture plate and a movable aperture plate disposed upstream of the fixed aperture plate in the direction of rotation of the drum. A variable transmission connected between an exposure knob and the movable aperture plate transmits rotation of the knob to the movable aperture plate at a rate corresponding to the magnification. In addition, a side edge of the document is aligned at the same position for all magnifications. The movable aperture plate is formed with a curved edge facing the fixed aperture plate, the center of the curved edge being aligned with the center of the image at all magnifications. As end plate is positioned by a sheet feed mechanism to prevent image formation on a portion of the drum in which the image would not be transferred to an undersized copy sheet.

摘要： A large number of copies of a small original document such as a card are made quickly by forming electrostatic images of the document circumferentially spaced from each other on the periphery of a rotating photoconductive drum. The electrostatic images are repeatedly developed and the resulting toner images are transferred to respective copy sheets to form copies. In this manner, a number of copies equal to the number of electrostatic images on the drum are produced for each revolution of the drum. However, due to unavoidable discharge of the electrostatic images the same can only be developed a predetermined number of times if acceptable copies are to be produced. The present apparatus therefore comprises an automatic means for forming new electrostatic images when the original electrostatic images have been developed the predetermined number of times. The automatic means may be in the form of a counter, a timer or a voltage sensor. An indicator is energized when the last required set of electrostatic images has been formed so that the original document may be removed from the apparatus. The developing means is de-energized after the last required developing operation has been completed.
摘要翻译：通过在旋转的感光鼓的周边上形成周向彼此间隔的文件的静电图像，快速地制作大量的诸如卡片的小原件的副本。重复显影静电图像，并将所得到的调色剂图像转印到相应的复印纸上以形成副本。以这种方式，对于滚筒的每转都产生等于滚筒上的静电图像数量的多个拷贝。然而，由于不可避免的静电图像的放电，如果要生产可接受的拷贝，则只能发展预定次数。因此，本装置包括当原始静电图像已经显影预定次数时形成新的静电图像的自动装置。自动装置可以是计数器，定时器或电压传感器的形式。当形成最后所需的静电图像集时，指示器被激活，使得原始文件可以从设备中移除。显影装置在最后所需的显影操作完成之后被断电。

摘要： For producing a plurality of copies of an original document which has a length less than one-half a maximum document length which can be accomodated by the apparatus, a plurality of electrostatic images are formed on a rotating photoconductive drum by alternately forming an image on one image space and letting one or more image spaces pass before forming the next image. Development and transfer of the electrostatic images are effected during a last imaging revolution of the drum and may be further effected during subsequent revolutions of the drum for repeated development and transfer using the same electrostatic images. The number of electrostatic images formed on the drum is computed as a function of the length of the original document and the number of copies to be made to minimize the number of revolutions of the drum required to produce the copies and thereby maximize the copying speed. The number of electrostatic images formed is not necessarily the maximum number which can be formed on the drum.
摘要翻译：为了生产长度小于可由装置容纳的最大文件长度的一半的原始文件的多个副本，通过在一个图像上交替地形成图像，在旋转的感光鼓上形成多个静电图像图像空间，并在形成下一个图像之前让一个或多个图像空间通过。静电图像的显影和转印在滚筒的最后成像旋转期间进行，并且可以在滚筒的后续转动期间进一步实现，以便使用相同的静电图像反复显影和转印。根据原始文件的长度和要制作的副本的数量来计算形成在鼓上的静电图像的数量，以使产生复印件所需的转鼓的转数最小化，从而使复印速度最大化。形成的静电图像的数量不一定是可以在滚筒上形成的最大数量。

摘要： An electrophotographic copying machine capable of making a two-dimensional copy either from a two-dimensional or three-dimensional object is provided. In accordance with the present invention, if a three-dimensional object has portions which cannot be brought into contact with the top surface of the contact glass plate of the copying machine, adjusting means adjusts the focal distance to the location of such non-contact portions. The adjusting means may be any element of the optical system which is constructed to be shiftable to change the focal distance to a point of interest above the contact glass plate. Alternatively, the adjusting means may include a new element additional to the optical system.

摘要： The entire surface of a photoconductive drum is developed with a toner substance after imaging, and a copy sheet is fed into contact with the drum for transfer of the toner image thereto. If the copy sheet is smaller than the maximum image area of the drum, toner from the portion of the drum outside of the edges of the copy sheet will be transferred to transfer and separating rollers and the like to contaminate the same if not removed. The invention provides a brush which slidably contacts the exposed back surface of the copy sheet and the portion of the drum outside the edges of the copy sheet to remove the toner from this portion prior to separating the copy sheet from the drum.

摘要： A plurality of images of the same original document are formed at equal spacing on the circumference of a photoconductive drum. After all of the images are completely formed, the images are developed a number of times, and the resulting toner images are transferred to copy sheets after each developing step. The method comprises forming an image on one section of the drum and then rotating the drum by a plurality of image spaces before forming an image on another section. The number of image spaces skipped is determined by the number of images to be formed in such a manner that the images will be formed only once during a predetermined number of rotations of the drum.

摘要： The exposure process and apparatus are for use with electrophotographic copying machines of the type in which a photosensitive surface is moved at a constant rate at any magnification selected. Upon changing from a magnification of unity to a magnification of .beta., a lens means arrangement which may be of any type, e.g., a customary lens, a variable focus lens, a lens of in-prism or in-mirror construction, is displaced, in a direction perpendicular to the optical axis thereof at unity magnification, by a distance which is determined in accordance with .beta. and another factor so that the same position for placement of an original to be copied on a holder such as a glass plate, can be maintained as the magnification is varied.

摘要： An original feeding system having a rotary drum provided with sheet original hold-down claws for clamping the leading edge of the sheet original against the surface of the periphery of the rotary drum and with a control mechanism for keeping the claws in clamping engagement with the sheet and releasing the claws from clamping engaging therewith. A belt drive is provided for feeding the copy sheet by holding same between the rotary drum and the belt. The rotary drum is adapted to be stopped in its rotation before it completes one revolution, while the belt drive continues to be driven to feed the sheet original, which is subjected to the frictional force exerted by the belt and slides along the surface of the rotary drum. Therefore, it is possible to feed a sheet original having a length larger than the circumferential length of the rotary drum.
