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.

The detection unit includes a support, an arm supported by the support swingably around a swing shaft, and a sensor for detecting a displacement of the arm relative to the support. The arm includes contactors. The movement mechanism keeps the contactors away from a feed plane during a feed phase of a sheet panel, and moves the contactors to the feed plane and then moves the contactors from the feed plane during a pause phase of the sheet panel. The defect detecting device further includes a determination part configured to determine whether a defect in bag making is present based on data from the sensor.

A printing apparatus includes a plurality of set units to set rolled print media, a conveyance unit to convey the print media, a printing unit, a detection unit, and display units.
