A paper-reversing device includes: a driving roller that rotates in one direction; a plurality of driven rollers that are installed around the driving roller while being kept in contact with the driving roller, and that revolve around the driving roller while rotating on their respective axes following the rotation of the driving roller. There is a paper-sending roller that rotates without contacting the driving roller; a roller supporting plate for supporting the driving roller and the driven rollers; a paper-feeding guide section; a paper-reversing guide section; and a solenoid. Paper, which has been fed to the paper-feeding guide section, is sent to the paper-reversing guide section by being sandwiched between the driving roller and one of the driven rollers. Thereafter, the driven roller is separated from the driving roller and is pressed against the paper-sending roller by the revolution. As a result, the rear end of the paper is sandwiched between the paper-sending roller and the driven roller to be discharged. This paper-sending operation can be carried out simultaneously with the next round of paper-feeding operation of paper by the driving roller and another driven roller. Therefore, it becomes possible to provide a shorter paper interval with respect to the paper-sending operation of paper.
