Abstract
A transport device includes a first driving roller configured to contact an outer circumferential surface of a roll body on which a medium is wound, and apply rotational torque to the roll body, a second driving roller configured to unwind the medium from the roll body, a first drive unit configured to drive the first driving roller, a second drive unit configured to drive the second driving roller, and a control unit configured to control the first drive unit and the second drive unit. The control unit controls the first drive unit, based on a magnitude of a load current flowing in the second drive unit.
