A partition arm for detecting that the original has been circulated once; a rotation direction detection means for detecting the rotation direction of the partition arm; and a stack of originals is stacked on the document mounting table based on the detection output of the rotation direction detection means. An automatic document feeder comprising: determination means for determining whether the amount of documents is appropriate and whether or not the document circulation operation has been properly completed. (2) The rotational direction detection means rotates in conjunction with the partition arm, and has a side surface facing a rotating plate formed such that the density changes along the rotational direction, and detects a change in the density of the rotating plate. 2. The automatic document feeder according to claim 1, wherein the rotational direction of the partition arm is detected based on the direction.
