    • The present invention relates to a sheet conveying apparatus for conveying a sheet in recirculation. The apparatus comprises a feed tray, a feed mechanism, a recirculation conveying mechanism for conveying the sheet fed by the feed mechanism to return it to the feed tray. The recirculation conveying mechanism includes a discharge tray on which the plurality of sheets are temporally discharged and accumulated and a moving mechanism for moving the sheets accumulated on the discharge tray to the feed tray. The apparatus further comprises a feed sensor detecting whether or not any sheets present on the feed tray. The sheets discharged on the discharge tray are moved to the feed tray by the moving mechanism when all sheets on the feed tray are fed and the feed sensor detects none of the sheet.
    • 本发明涉及一种用于在再循环中输送片材的片材输送装置。 该装置包括进料盘,进料机构,再循环输送机构,用于输送由进料机构供给的纸张以将其返回进料盘。 再循环输送机构包括:排出托盘,多个纸张在其上被排出和累积;以及移动机构,用于将堆积在排出托盘上的纸张移动到进给托盘。 所述装置还包括进给传感器,检测进纸托盘中是否存在任何纸张。 当进给托盘上的所有纸张进给时,排出托盘上排出的纸张通过移动机构移动到进纸盘,进给传感器检测不到纸张。

    • 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。
