ABSTRACT:
An original transporting device for transporting an original to an exposure unit of a copying machine which includes a loading tray for loading the originals, a first separation unit, a first transporting unit, a second separation unit, a second transporting unit, a third transporting unit for transporting the original transported by the first transporting unit in a first direction, stopping it at the exposure unit, then transporting it in a second direction and transporting the original transported by the second transporting unit in the second direction to pass through the exposure unit. Finally, an ejection system is included for ejecting the original transported by the third transporting unit from the exposure unit in the second direction on to the loading tray, where the transporting speed of the second transporting unit is higher than the transporting speed of the third transporting unit in the second direction, where the original interval between the previous original and the current original can be rendered closer to accord the maximum ability of the copying machine so that the maximum productivity can be attained.
