Both-face automatic original feeding apparatus

摘要

A both-face automatic original feeding apparatus wherein a plurality of originals having images on their first and second surfaces are successively supplied from an original stacking portion to a predetermined position for reading an original, and each original is reversely rotated through a switch-back path after the first surface of the original passes through the predetermined position, thereby supplying the original to the predetermined position again to direct the second surface of the original to the predetermined position. In such a feeding apparatus, there is provided an introduction path for directing the original supplied from the original stacking portion to the predetermined position; a first discharge path for directing the original to the switch-back path after the original passes through the predetermined position; a surface reverse path for directing the original from the switch-back path to the predetermined position after reversing a first surface and a rear surface of the original; and a controller for controlling the apparatus in such a manner that a preceding original is switched back to convey it in the surface reverse path while a succeeding original is being passed through the predetermined position, and, when a trailing end of the succeeding original leaves the predetermined position, a tip end of the preceding original reaches the predetermined position.
