Abstract: An original handling apparatus is provided with a conveyor, a setting circuit and a control system. The conveyor conveys an original in plural modes in which an original is scanned. The conveyor is operated in a first convey mode in which an original is fed to and stopped at a first position on a platen. After the scan is completed, the scanned original is fed to and stopped at a second position on the platen, and a next original is fed to and stopped at the first position on the platen. In the second convey mode, the original is fed to and stopped at the first position on the platen, and after scan is completed, the original is discharged from the first position. A next original is then fed to and stopped at the first position on the platen. The setting circuit sets either the first or second convey modes.
