Abstract

A document feeder includes a mode selector, at least two document sensors, and a feeding determiner. The mode selector receives selection of either a normal mode for feeding documents having the same size or a mixed loading mode for feeding documents having different sizes. The document sensors are arranged at an interval in a width direction of the documents, and detect the documents. The feeding determiner performs, based on results of the detection by the document sensors, a size determination to determine a size of a document being fed and a skew determination to determine whether or not the document being fed is skewed. The feeding determiner performs the skew determination when the normal mode has been selected and performs the size determination when the mixed loading mode has been selected.
