    • A document feeder for advancing original documents to the exposure platen of an electrophotographic copier which is capable of operating in either a semiautomatic or fully automatic mode. In the semiautomatic mode, an original to be copied is manually inserted face up into an inlet where it is engaged by the semiautomatic transport assembly inverted and advances to a proper position for copying. After exposure the document is again inverted and guided into a receiving tray overlying the platen. In the automatic mode of operation, a second tray normally maintained in an inoperative position is swung down to a position at which its feed end is adjacent the feeder inlet. Documents to be copied are placed face up as a stack in the second tray, and feed rollers carried by the tray are actuated to advance documents individually from the stack to the inlet. In a preferred embodiment, a driven feed roller is disposed below the retarding roller at a fixed spacing therefrom to feed sheets from the bottom of the stack so that the sheets are collected in the stacking tray in their original order. In the same embodiment, a guide strip having fingers extending between the feed roller and reduced-diameter portions of the retarding roller is resiliently urged into engagement with the feed roller to press the sheet being fed firmly against the roller to ensure reliable feed regardless of sheet thickness.
    • 一种用于将原始文档推送到能够以半自动或全自动模式操作的电子照相复印机的曝光台的文档馈送器。 在半自动模式下,将要复制的原件手动地插入到入口中,其中半自动运输组件被倒置并进入适当位置进行复制。 曝光后,文件再次反转并被引导到覆盖压板的接收盘中。 在自动操作模式中,通常保持在不工作位置的第二托盘向下摆动到其进给端邻近进料器入口的位置。 要复印的文件以堆叠方式放置在第二个托盘中,并且启动由托盘承载的进给辊将文档单独地从堆叠推进到入口。 在优选实施例中,驱动进给辊以与其隔开的固定间隔设置在延迟辊的下方,以从纸堆的底部进给纸张,使得纸张以原始顺序收集在堆垛托盘中。 在相同的实施例中,具有在进给辊和延迟辊的直径减小部分之间延伸的指状件的引导条被弹性地推动成与进给辊接合,以将被牢固地供给辊的片材推压到辊子上,以确保可靠的进给而不管片材 厚度。

    • An improved pick-off device for a copying machine of the type in which the developed image is transferred from the surface of a photoconductor to a sheet of copy paper in which a thin semi-rigid blade having a knife edge at a transversely tapered end thereof is releasably secured to a resiliently restrained element of a clutch assembly mounted at a position at which the knife edge of the blade is resiliently biased into engagement with the photoconductor at a location in the path of the leading edge of a sheet to which an image has been transferred to guide the sheet into a narrow space between the normally stationary clutch element and a continuously driven clutch element. In response to the entry of the sheet into the narrow space the two clutch elements are coupled to cause the restrained element to move with the continuously driven element against the action of the restraining means to carry the sheet away from the photoconductor surface. After a predetermined concomitant rotation of the clutch elements as the leading edge of the copy sheet enters the nip between an upper delivery roller and a lower delivery roller which moves with the continuously driven clutch element, the normally restrained clutch element is advanced relatively to the continuously driven clutch element to release the sheet and to restore the knife edge precisely to its initial position.
    • 一种用于复印机的改进的拾取装置,其中显影图像从感光体的表面转印到复印纸的薄片上,其中具有在其横向锥形端的刀刃的薄的半刚性刀片 可释放地固定到离合器组件的弹性约束元件,该离合器组件安装在刀片的刀刃被弹性偏置成与图像具有的片材的前缘的路径中的位置处的光电导体接合的位置处 被转移以将片材引导到通常静止的离合器元件和连续驱动的离合器元件之间的狭窄空间中。 响应于纸张进入狭窄空间,两个离合器元件被联接以使受限元件随着连续被驱动的元件移动而克服限制装置的作用而将纸张远离光电导体表面运送。 当复印纸的前缘进入预定的伴随旋转的离合器元件进入上部输送辊和下降输送辊之间的辊隙时,其与连续驱动的离合元件一起移动,通常约束的离合器元件相对于连续地前进地前进 驱动的离合器元件以释放片材并将刀刃精确地恢复到其初始位置。

    • A jam detector for use in a plain paper copying machine of the type in which the copy paper to which the image has been transferred from the surface of a photoconductive drum is removed from the drum by a pick-off element which acts on a narrow strip of the copy paper extending rearwardly from the leading edge of the paper along one side edge thereof wherein the leading edge of a narrow or skewed or otherwise misdirected copy paper which misses the pick-off element is engaged by a jam detector element positioned in the path of the paper a predetermined distance inboard of the pick-off element to cause the jam detector element to disable the machine and to illuminate the jam indicating signal light. The arrangement is such that the machine cannot be reset for the next operation until such time as the jammed copy paper is removed from the machine. In an alternate embodiment, the jam detector element directs the sheet which has missed the pick-off element to guides which carry the paper back toward the output rolls of the machine which feed the paper back to the usual delivery location.
    • 用于普通纸复印机的卡纸检测器,其中从感光鼓的表面转印了图像的复印纸通过作用在窄条上的拾取元件从滚筒中移除 复印纸的一个侧边缘从纸张的前边缘向后延伸,其中错过该拾取元件的狭窄或倾斜或其它错误的复印纸的前缘被位于路径中的卡纸检测器元件接合 的纸张在拾取元件的内部预定距离,以使卡纸检测器元件禁用机器并照亮卡纸指示信号光。 这种布置使得机器不能被复位用于下一个操作,直到卡住的复印纸从机器移除为止。 在替代实施例中,卡纸检测器元件将已经错过了拾取元件的纸张引导到将纸张运送到机器的输出辊的引导件上,该纸张将纸送回到通常的输送位置。
