Medium transporting device and recording apparatus

A medium transporting device comprising:

• a curved path in which the medium processed by a processing unit is curved inversely through an inner curved portion and an outer curved portion;
• a plurality of first ribs that extend in a medium transportation direction in a facing area facing the processing unit or on the upstream of the facing area in the medium transportation direction, that are provided at intervals in a width direction intersecting the medium transportation direction, and that form a wave-like shape on the medium, the wave-like shape being formed by a plurality of mountain portions and a plurality of valley portions extending in the medium transportation direction and alternately positioned in the width direction;
• a plurality of second ribs that extend in the medium transportation direction on the outer curved portion and are provided at intervals in the width direction;
• and
• a plurality of third ribs that extend in the medium transportation direction on the inner curved portion and are provided at intervals in the width direction,
• wherein the plurality of second ribs and the plurality of third ribs are disposed at positions in the width direction that correspond to the plurality of mountain portions and the plurality of valley portions of the wave-like shape of the medium that is formed by the plurality of first ribs.
