A drive transferring unit includes a first roller, a second roller, a first clutch, a second clutch, a transferring section, and a control section. The first roller includes a first shaft section. The second roller includes a second shaft section. The first clutch switches between enabling transfer of a driving force to the first shaft section and interrupting transfer thereof. The second clutch switches between enabling transfer of the driving force to the second shaft section and interrupting transfer thereof. The transferring section transfers the driving force from one of the first roller and the second roller to the other. The control section selects between first control in which the first clutch is in the on state and the second clutch is in the off state and second control in which the second clutch is in the on state and the first clutch is in the off state.

An image processing apparatus includes a selection unit, a determination unit, and a control unit to set candidates to be selected by the selection unit. If determination unit determines that there is not a set of a size and an orientation of a document of which the orientation cannot be correctly determined, the control unit sets, as selection unit selection candidates, candidates of sets of sizes and orientations of a plurality of documents. If the determination unit determines that there is a set of a size and an orientation of a document of which the orientation cannot be correctly determined, the control unit sets, as selection unit selection candidates, candidates obtained by excluding the set of the size and the orientation of the document of which the orientation cannot be correctly determined from the candidates of the sets of the sizes and the orientations of the plurality of documents.
