Abstract:
1. A medium transport device comprising: a medium transport pathway that inverts a medium that is supplied from a processing unit that forms an image on the medium, and is configured to transport the medium to the processing unit again after the medium is inverted; a discharge unit that discharges the medium that is supplied from the processing unit; a first supply unit that supplies a first medium; a first convergence unit at which the first supply unit and the medium transport pathway converge; a second supply unit that supplies a second medium; a second convergence unit that is positioned further downstream than the first convergence unit, and at which the second supply unit and the medium transport pathway converge; a first transport roller that has a first driving roller and a first driven roller that is associated with the first driving roller, and that is provided in the first convergence unit; a second transport roller that has a second driving roller and a second driven roller that is associated with the second driving roller, and that is provided in the second convergence unit; and wherein the first transport roller and the second transport roller are separated, wherein the first driving roller forms a bent portion of the medium transport pathway to invert the medium, wherein the first driving roller inverts the medium supplied from the first supply unit, wherein the second driving roller transports the medium from the first transport roller to the processing unit.
