摘要： The invention provides an image reader provided with an automatic document feeder which has a switchback path and can perform a both-faces processing operation, and which makes it possible to simplify the control of a switchback operation and handle a long-sized document sheet without making the diameter of a feed roller large and making the switchback path unnecessarily long. An automatic document feeder of the invention comprises a feed path for feeding a document sheet drawn out from a paper feed stacker to an image reading portion facing a feed roller, a switchback path c for making a document sheet which has been processed at the image reading portion switchback, a pair of switchback rollers which are provided so as to make a document sheet switchback in the switchback path and are able to turn forward and backward, and a paper discharge path for discharging a document sheet being in the switchback path onto a paper discharge stacker. Here, the switchback path c is provided in a casing below the paper discharge stacker and the casing has an opening formed in it so that the fore end of a document sheet guided into the switchback path projects from the casing. Further, the pair of switchback rollers are disposed at the downstream side in the switchback path so that the fore end and the rear end of a document made to switchback do not overlap each other through the feed roller.
摘要翻译：本发明提供了一种具有自动文件进给器的图像读取器，其具有转折路径并且可以执行双面处理操作，并且这使得可以简化转向操作的控制并且处理长尺寸的文档片而不进行进料辊的直径很大，使得回转路径不必要地长。本发明的自动文件进给器包括用于将从进纸堆垛机引出的文档片材馈送到面向进给辊的图像读取部分的进给路径，用于制作在图像读取处理过的文档片材的转折路径c 一对转向辊，其设置成使折返路径中的文件纸张回转并能够前后转动;以及纸张排出路径，用于将位于转回路径中的文件纸张排出到纸张上放电堆垛机这里，转向路径c设置在排纸堆叠器下方的壳体中，并且壳体具有形成在其中的开口，使得引导回转路径的文件纸张的前端从壳体突出。此外，一对回转辊设置在转向路径中的下游侧，使得通过进给辊不能重叠的文件的前端和后端被翻转。
