Claim:
A paper ejector unit which transports a printed paper to an exit slot along a paper path, comprising: the paper path comprising a first path, a second path provided in a lower position than the first path, and a guide provided between the first and second paths and including an inclined face to restrict an upward deflection of the paper when the paper is transported forward to the exit slot; a reversible transportation roller assembly in the middle of the second path, the reversible transportation roller assembly being configured to be rotated forward to transport the paper forward to the exit slot, to be reversely rotated to withdraw the paper having been transported to the exit slot, and to stop rotating to stop transporting the paper; an opening formed downward at a forward back end of the second path, the opening being located and configured so as to guide the paper to loop downwardly for temporary retainment when the reversible transportation roller assembly stops transporting the paper; and a third path branching downward from the second path and provided in the vicinity of a forward upstream side of the reversible transportation roller assembly in order to recover the paper.
