Abstract
According to an automatic document feeder of a multifunction peripheral according to the present invention, two tilt sensors are provided in the middle of a document conveyance path to detect a tilt degree of a document being conveyed along the document conveyance path. Here, for example, if the positional deviation representing the tilt degree of the document is greater than a predetermined threshold value ΔLs, the conveyance of the document is stopped. On the other hand, if this is not the case, the conveyance of the document is continued. In addition, the threshold value is set in accordance with the width dimension of the document, and in particular, the larger the width dimension, the smaller the threshold value.
