1. A document reading apparatus comprising:
a stacking portion on which a plurality of documents are stacked;
a feeding unit configured to feed the plurality of documents in a feeding direction one by one from an uppermost one of the plurality of documents stacked on the stacking portion;
a reading unit configured to read the documents fed by the feeding unit;
a drive source configured to drive the feeding unit; and
a control unit configured to execute a mode in which the plurality of documents having different sizes are fed by the feeding unit and read by the reading unit, the plurality of documents being stacked on the stacking portion such that a document having a smaller width in a width direction orthogonal to the feeding direction is disposed higher, the control unit being configured to control the drive source in the mode such that the feeding unit feeds a first document at a first feeding speed, and the feeding unit feeds a second document following the first document at a second feeding speed higher than the first feeding speed in a case where a width of the first document is larger than a predetermined width.
