    • An automatic document conveyor for an image processing machine having an endless belt with a driven roller and a follower roller. The endless belt mechanism includes a front frame and a rear frame which are coupled together a distance apart in the direction substantially perpendicular to the longitudinal direction of the endless belt. First and second movable frames are coupled to first ends of each of the front frame and the rear frame and support the follower roller. A third movable frame is coupled to the second end of the front frame. The driven roller is supported by the third movable frame and the second end of the rear frame, and a drive source is coupled to the end of the driven roller adjacent the rear frame. Springs urge the three movable frames in directions tensioning the endless belt. The first and second movable frames can be moved against their springs to release the tension of the follower roller on the endless belt. The third movable frame can be moved against its spring to release the tension of the driven roller on the endless belt while retaining the coupling of the endless belt with the drive source.
    • 一种用于图像处理机的自动文件输送机,具有带有从动辊和从动辊的循环带。 环形带机构包括前框架和后框架,它们在与环形带的纵向方向基本垂直的方向上分开连接在一起。 第一和第二可移动框架联接到前框架和后框架中的每一个的第一端并支撑从动辊。 第三可移动框架联接到前框架的第二端。 从动辊由第三可移动框架和后框架的第二端支撑,并且驱动源联接到邻近后框架的从动辊的端部。 弹簧在张紧环形带的方向上推动三个可动框架。 第一和第二可移动框架可以抵靠其弹簧移动以释放随动辊在环形带上的张力。 第三可移动框架可以抵靠其弹簧移动以释放从动辊在环形带上的张力,同时保持环形带与驱动源的联接。

    • In a paper transport device, a first roller serving as a separation roller is situated underneath a second roller serving as a document feed roller, together forming a roller pair. A rotary shaft of the separation roller is biased upward toward the document feed roller by means of an elastic element. One end of the rotary shaft is connected to a drive shaft via a coupler while a connecting bar is joined to the other end of the rotary shaft obliquely from above. An extreme end of the connecting bar opposite to the rotary shaft is attached to a support plate fixed to a main body of the paper transport device in such a way that the connecting bar can swing about pivot pin fixed to the support plate. In the paper transport device thus constructed, one end of the rotary shaft fitted to the coupler acts as a point of support, allowing the other end of the rotary shaft to move downward overwhelming an upward-lifting force of the elastic element when forced downward by the connecting bar. In this construction, the separation roller can be separated from and brought into contact with the document feed roller.
    • 在纸传送装置中,用作分离辊的第一辊位于用作原稿进给辊的第二辊的下方,一起形成辊对。 分离辊的旋转轴通过弹性元件朝着原稿供给辊向上偏置。 旋转轴的一端通过联轴器连接到驱动轴,而连接杆从上方倾斜地连接到旋转轴的另一端。 与旋转轴相对的连接杆的末端连接到固定到纸张传送装置的主体的支撑板上,使得连接杆能够围绕固定到支撑板的枢轴销摆动。 在这样构成的纸张输送装置中,装配在联轴器上的旋转轴的一端作为支撑点,使得当被强制向下时,旋转轴的另一端向下移动,弹性元件向上的力向下移动, 连接条。 在这种结构中,分离辊可以与送纸辊分离并与其接触。

    • An automatic document feeder for an image processing machine. The document feeder includes a main frame to be pivotally mounted on the image processing machine, a paper feeding unit, a paper discharging unit, and a conveyer belt for conveying papers from the paper feeding unit, across the image processing machine for image processing, to the paper discharging unit for discharge. A document discharging tray is positioned above the conveyer belt for receipt and stacking of papers discharged from a discharge port of the paper discharging unit. In the direction of document discharge, the document discharging tray has an ascending inclination, followed by a descending inclination. The ascending inclination and the descending inclination define a vertex spaced from the discharge port in the document discharging direction by more than one-half the length of the maximum-length document to be processed by the image processing machine.
    • 一种图像处理机的自动送纸器。 文件进给器包括可转动地安装在图像处理机上的主框架,送纸单元,排纸单元和输送带,用于将纸张从供纸单元传送到图像处理机用于图像处理,到 出纸单元。 文件排出托盘位于输送带上方,用于接收和堆放从排纸单元的排出口排出的纸张。 在文件排出的方向上,文件排出托盘具有上升的倾斜度,随后是下降的倾斜度。 上升倾斜和下降倾斜定义了在文件排出方向上与排出口间隔开的顶点超过由图像处理机处理的最大长度文档的长度的一半以上。
