    • An automatic document feeder includes a document stacker for holding documents, a first conveyer for feeding the documents one sheet by one sheet to a platen glass for reading an image on a first side of the conveyed document, a second conveyor for conveying the conveyed document so that the conveyed document is turned over and conveyed to the platen glass again to read an image on the second side, and a discharger for discharging the conveyed document from the platen glass and returning the conveyed document to the document stacker. A third conveyer, located over the platen glass, conveys the conveyed document from at least one of the first conveyor and the second conveyer to the platen glass and conveys the conveyed document from the platen glass to at least one of the first conveyer, the second conveyer, and the discharger. A controller controls the movement of the conveyed document by the first, second, and third conveyers and the discharger, and a next conveyed document following the conveyed document is set to a waiting position on the platen glass when a second circulation is executed by the controller following a first circulation. The next conveyed document is then conveyed to the platen glass through the second conveyer after the second side of the conveyed document is read.
    • 自动进稿器包括用于保存文件的文件堆垛机,用于将文件一张一张地送入稿台玻璃的第一输送机,用于在所输送的文件的第一面上读取图像;第二输送机,用于输送所传送的文件, 输送的文件被翻转并再次传送到稿台玻璃上以读取第二侧上的图像,以及用于将被输送的文件从稿台玻璃中排出并将所传送的文件返回到文件堆垛机的排放器。 位于压板玻璃上方的第三输送机将输送的文件从第一输送机和第二输送机中的至少一个输送到压板玻璃,并将所输送的文件从压板玻璃输送到第一输送机,第二输送机 输送机和排放器。 控制器控制由第一,第二和第三输送机和放电器输送的文件的移动,并且当由控制器执行第二循环时,跟随传送的文件的下一个传送的文件被设置在稿台玻璃上的等待位置 在第一次流通之后。 在读取所传送的文件的第二面之后,下一个传送的文件通过第二传送器传送到稿台玻璃。

    • An automatic document conveying device has a stack tray on which a plurality of documents are stacked; a feeder by which the documents stacked on the stack tray are separated and fed one by one; at least one pair of conveying rollers provided downstream of the feeder; a reading position for reading document information from said separated documents positioned downstream of the at least one pair of conveying rollers; a conveyor provided opposite to the reader for conveying separated documents to the reading position; a discharger positioned downstream of said reading position for discharging documents after said conveyor conveys the documents to the reading position, a conveyance path on which a plurality of documents are sequentially located between the feeder and the reading position; the conveyance path having predetermined stand-by positions provided on the conveyance path at which documents, subsequent to a document positioned at the reading position are stopped; a document detector provided between the at least one pair of conveying rollers and the conveyor; an encoder which generates a pulse signal corresponding to a rotation of the conveyor; and pulse counter for counting the encoding pulses. A document conveyance to the reading position by the conveyor is controlled based on a number of pulses counted by the pulse counters on the basis of a detection timing by the document detector.
