摘要： 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.
摘要翻译：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。

摘要： An automatic document feeder (ADF) for feeding a document across a platen is attachable to different types of copying machines which have different copying speeds. The ADF has a detector for detecting the copying speed of the copy machine and a controller for adjusting the document feeding speed of the ADF to the copying speed of the copy machine. The controller also controls the feeding speed of the document at a standard speed in a condition which does not lower copying efficiency and at a higher speed in a condition which lowers copying efficiency. A condition which does not lower copying efficiency is feeding documents other than the last document from the platen. A condition which lowers copying efficiency is feeding the first document to the platen and ejection of the last document from the platen.

摘要： A copying machine having a two-in-one copying mode has a pickup roller 65, a separating roller 75, a register roller 90, a conveyor belt 95 and a pinch roller 101. The pickup roller 65 and the separating roller 75 feed a document toward a glass platen 29 one by one to stop the document at a first-out position. The register roller 90 conveys the document fed by the pickup roller 65 and the separating roller 75 onto the glass platen. The conveyor belt 95 conveys the document conveyed by the register roller 90 along the glass platen 29 until a rear end of the document reaches a predetermined switch-back position, then conveys the document in the opposite direction to retreat a predetermined distance, and then conveys the document as well as a succeeding document stopped at the first-out position such that a front end of the document situated on a downstream side of the document conveying direction may be aligned with an exposure reference SP, and then discharges the documents to the downstream side of the document conveying direction after exposure. The pinch roller 101 conveys the documents discharged by the conveyor belt 95 from the glass platen 29 to a discharge section 115.

摘要： A pickup member forwards a document at a forwarding position where the pickup member is brought in contact with a bunch of stacked sheets, and is retracted from the forwarding position after the leading end of the document is forwarded. Before the rear end of the document previously forwarded passes through the pickup member, the pickup member is moved to the forwarding position and positioned thereat for forwarding the following document. A rotative member of a pair of separating members is rotated with a first velocity to transport a document forwarded by the pickup member to a downstream side, and a transport member is rotationally driven with a second velocity to further forward the document transported from the separating member to the downstream side. A pressing member of the pair of separating members presses the document against the rotative member with a first pressing force when the document is transported with the first velocity, and further presses the document with a second pressing force when the document is transported with the second velocity by the transport member whereby the documents being transported are separated.
