ABSTRACT:
An automatic original feeding apparatus includes an original reading portion, a first feeder disposed upstream of the original reading portion, and a second feeder capable of receiving two originals simultaneously. The second feeder is disposed downstream of the original reading portion, for turning up and resupplying the two originals one after another to the original reading portion. The apparatus also includes a third feeder for directing the two originals resupplied to the original reading portion to a discharge portion. The apparatus also includes a detector for detecting delay in conveyance of a succeeding original. A controller in the apparatus delays feeding of a succeeding original when the delay in conveyance is detected and introduces the succeeding original into the second feeder, after a preceding original in the second feeder is discharged from the second feeder.
