A transport apparatus includes a feed unit as an example of a supply unit which supplies a medium in a transport direction, and a transport unit which transports the medium supplied from the feed unit. The transport unit includes a transport roller (a driving roller) which sends the medium, and a driven roller which nips the medium between the transport roller and the driven roller. The driven roller is movable in the transport direction relative to the transport roller.

A recording apparatus includes a printing unit that performs a recording on a sheet, a third sheet feed unit that mounts a roll body on which the sheet is wound in a roll shape, unwinds the sheet from the roll body, and supplies the sheet to the printing unit, and a pressing portion that presses the roll body mounted on the third sheet feed unit, in which the pressing portion presses the mounted roll body in a direction opposite to a direction of taking out the roll body from the third sheet feed unit.

A base material processing apparatus includes a transport mechanism, a force detection part, a meandering prediction part, a processing part, and a controller. The transport mechanism transports an elongated strip-shaped base material in a longitudinal direction thereof along a transport path aimed by a plurality of rollers of the transport mechanism. The force detection part detects a force applied to a sensing roller in an axial direction of a rotation shaft thereof, the sensing roller being at least one of the plurality of rollers. The controller predicts the meandering state of the base material to output meandering prediction information, based on the force applied to the sensing roller in the axial direction of the rotation shaft thereof. The meandering prediction part corrects the widthwise position of the base material relative to the processing part, based on the meandering prediction information. Thus, the base material processing apparatus is capable of sensing the meandering state of the base material through the use of the existing rollers of the transport mechanism in the processing part, and is capable of correcting the widthwise position of the base material relative to the processing part.
