ABSTRACT:
An automatic document feeder includes an input tray, a transfer path, a roller assembly, an ejecting tray, a light emitter, a light receiver, a comparator and a discriminating unit. The light emitter successively emits multiple light beams of different intensities to the document. When the multiple light beams penetrating through the document are received by the light receiver, the light receiver outputs corresponding voltage signals. The discriminating unit is electrically connected to the light receiver for discriminating document types according to the voltage levels of the voltage signals.
