    • A sheet feeding apparatus has a forwarding device for successively forwarding a plurality of sheets accommodated in a state of stacked layer one by one. The forwarding device is movable between a sheet forwarding position where the forwarding device is brought in contact with the leading end of a sheet for forwarding the sheet and a retracted position where the forwarding device is separated away from the sheet. The apparatus includes a transport device for receiving a sheet forwarded by the forwarding device and transporting the sheet in a predetermined direction of transport. The apparatus also includes a control device for controlling a timing of movement of the forwarding device, wherein the control device forwards a sheet by positioning the forwarding device at a forwarding position and moves the forwarding device to a retracted position after the leading end of the sheet is forwarded by the forwarding device, and further start moving the forwarding device to the forwarding position for forwarding the following sheet before the rear end of the sheet previously forwarded passes through the forwarding device, and the forwarding device is positioned at the forwarding position after the rear end of the sheet previously forwarded has passed through the forwarding device.
    • 片材进给装置具有转发装置,用于逐层地依次转发多个堆叠状态的片材。 转发装置可以在转发装置与用于转发纸张的纸张的前端接触的纸张转送位置和转印装置与纸张分离的缩回位置之间移动。 该装置包括用于接收由转发装置转发的纸张并沿预定的运输方向运送纸张的运输装置。 该装置还包括用于控制转发装置的移动定时的控制装置,其中控制装置通过将转发装置定位在转发位置来转发纸张,并且在纸张的前端之后将转发装置移动到缩回位置 由转发装置转发,并且进一步开始将转发装置移动到转发位置,用于在先前转发的片段的后端通过转发装置之前转发下一个片段,并且转发装置位于转发装置之后的转发位置 先前转发的纸张的后端已经通过转发装置。

    • An automatic document feeder having a pick-up roller for feeding a document out of a tray, a conveyer belt for conveying and stopping the document on a platen and ejecting the document from the platen, and a register roller for stopping the document fed by the pick-up roller once and feeding the document onto the platen. A driving mechanism for driving the belt and the register roller is connected with the belt and the register roller with no clutches in-between. The driving mechanism is driven by pulses, and the document conveying amount is controlled by detecting the number of pulses. In the automatic document feeder, if two successive documents are of a size smaller than a half of the platen, the two documents are set on the platen side by side, and a next document is fed out of the tray. If a latter document of two successive documents is of a size larger than a half of the platen, feeding of a next document is inhibited. Further, if two successive documents are of a size smaller than the platen, the documents are fed successively and intermittently to a pre-step position where the leading edge of a document is positioned at an intermediate reference point which is located substantially in the center of the platen and then to a scanning position where the leading edge of a document is positioned at a scanning reference point which is located in a downstream portion of the platen, and a next document is fed to an entrance of the platen.
    • 一种自动进稿器,具有用于将文件从托盘送出的拾取辊,用于将文件传送和停止在压板上并将文档从压板上排出的输送带,以及用于停止由纸张供给的原稿的记录辊 拾取辊一次,并将文件送到压板上。 用于驱动皮带和对准辊的驱动机构与皮带和对准辊连接,其间没有离合器。 驱动机构由脉冲驱动,文件传送量通过检测脉冲数来控制。 在自动进稿器中,如果两个连续文件的尺寸小于平板的一半,则将这两个文档并排设置在稿台上,并将下一个文档从托盘中送出。 如果两个连续文件的后一个文件的尺寸大于压纸卷的一半,则禁止进给下一个文件。 此外,如果两个连续的文档的尺寸小于压板,则将文档依次和间歇地进给到文档的前边缘位于基本位于文档的中心的中间参考点的前置位置 压板,然后到扫描位置,其中文件的前缘位于位于压板的下游部分的扫描参考点处,并且下一个文档被馈送到压板的入口。

    • A document feeding apparatus includes a device for successively forwarding sheets accommodated in a state of stacked layer one by one; a transporter for receiving a sheet forwarded by the forwarding device and forwarding the sheet in a predetermined transport direction; a detector for detecting a sheet being transported by the transporter; and a controller for controlling operation of the transporter based on a result of a detection conducted by the detector, wherein the controller positions a rear end of a preceding sheet by transporting the sheet for a predetermined distance after the rear end of the sheet is detected by the detector, and positions a leading end of a following sheet at a predetermined position by transporting the following sheet for the predetermined distance after the leading end of the following sheet is detected by the detector, whereby the rear end of the preceding sheet and the leading end of the following sheet correspond with each other, and thereafter, the two sheets are forwarded simultaneously.
    • 文件馈送装置包括:一个接一个地依次转发以层叠状态容纳的片材的装置; 用于接收由所述转发装置转发的片材并沿预定的传送方向转发所述片材的传送器; 用于检测由所述运送器运输的片材的检测器; 以及控制器,用于基于由检测器进行的检测结果来控制运送器的操作,其中控制器通过在纸张的后端之后传送纸张预定距离来定位前一张纸的后端, 检测器,并且通过在检测器检测到后续片材的前端之后,通过传送后续片材预定距离来将后续片材的前端定位在预定位置,由此前一片材的后端和引线 下面的表格的结尾彼此对应,然后两张纸同时转发。
