Abstract
An original feeding apparatus includes a feeder tray for stacking originals, a separating device for separating the originals into a single sheet, and a feeding device for feeding the original to the separating device. The feeding device is raised or lowered between a feeding position where the feeding device contacts an uppermost original stacked on the feeder tray, and a retracted position where the feeding device is separated from the uppermost original. A drive device and a control device are disposed for raising and lowering the feeding device. The control device adjusts a rotating speed of the drive device for raising and lowering the feeding device according to a reading mode, so that the feeding device is lowered at a different speed to touch the uppermost original.
