Abstract: A roller shaft extends between a pair of frame walls. A feed roller is mounted on the roller shaft for feeding a stack of sheets placed on a feeding tray one by one from an uppermost sheet. A transmission gear is concentrically coupled to one end portion of the roller shaft to be rotated by driving of a driving motor. A boss extends axially inwardly from a center position of the transmission gear. The roller shaft has a flat key portion at the one end portion thereof. The flat key portion has a substantially D-shape in cross section. The flat key portion is coupled to the boss by being received in a non-circular hole of the boss. With this arrangement, an eccentric displacement of the roller shaft relative to the transmission gear is suppressed, and the feed roller is easily detachable from the roller shaft with a simplified operation.

Abstract: An automatic document feeder comprising a reversing device and a discharge device is disclosed. The reversing device and the discharge device are disposed such that the distance in the horizontal direction from an original document reading position in the automatic document feeder to the discharge device is longer than the distance in the horizontal direction from the original document reading position to the reversing device. This configuration allows the use of original documents whose length in the transport direction is short, and also shortens the transport path in the automatic document feeder as well as the amount of time needed to read an original document. Furthermore, this configuration increases the visibility of original documents discharged to the discharge tray by the discharge device because the discharge device is disposed relatively far away from the original document reading position.

Abstract translation: 公开了一种包括反转装置和放电装置的自动送纸器。 反转装置和排出装置被布置成使得从自动送稿器中的原稿读取位置到排出装置的水平方向上的距离比从原始文件读取位置到反转的水平方向的距离长 设备。 该配置允许使用在传送方向上的长度短的原始文档，并且还缩短自动文档馈送器中的传送路径以及读取原始文档所需的时间量。 此外，由于排出装置设置得比原始文件读取位置相对较远，所以这种配置增加了通过排出装置排放到排出托盘的原始文档的可视性。
