This invention discloses a paper eject passageway auto-switching device, which is installed in an information processing machine, suitable for automatically switching between two eject passageways for paper sheets from the processing unit. The paper eject passageway auto-switching device includes: a first paper eject passageway and a second eject passageway. The first paper eject passageway has a first guide vane provided with a guide surface capable of guiding paper sheets from the processing unit to move along the first paper eject passageway, and a first outlet portion through which paper sheets leave the information processing machine. The second paper eject passageway has a branched opening having its width smaller than that of the first guide vane, a second guide vane, and a second outlet portion. The second guide vane has a guide surface capable of guiding paper sheets from the branched opening into the second paper eject passageway. Paper sheets leave the information processing machine through the second outlet portion. The branched opening is located on the guide surface of the first guide vane, paper sheets of widths larger than that of the branched opening are guided to enter the first paper eject passageway and paper sheets of widths smaller than that of the branched opening are guided to enter the second paper eject passageway.
