    摘要： A control device of a transport device includes a control unit configured to control a roll motor for rotating a first rotary shaft on which a medium is held and a transport motor for rotating a first driving roller, a tension detection unit configured to derive, for each tension detection cycle, a detected tension value of a tension applied to a tension adjustment portion of the medium, and a tension F/B unit configured to calculate a tension F/B correction amount by feedback control based on a deviation between a target tension and the detected tension value. The control unit is configured to calculate a driving force by the roll motor based on the tension F/B correction amount, and control the roll motor based on the driving force.

    摘要： A medium feeding apparatus includes a roll holding portion which holds a roll body around which a printing medium is wound, a feeding roller which pulls out the printing medium from the roll body and feeds the printing medium, a roll motor which rotates the roll body held by the roll holding portion, a roll motor control portion which controls the roll motor, and rotation position detecting portions which detect a rotation position of the roll body, the roll motor control portion performs removing looseness of the printing medium pulled out from the roll body by driving the roll motor and rotating the roll body in a rewinding direction, and in the removing, driving of the roll motor is finished on the basis of movement of the rotation position detected by the rotation position detecting portions.

    摘要： A recording apparatus includes: a first driving unit that rotates a roll member; a second driving unit that drives a transport unit that transports a medium of the roll member; and a control unit that executes a first process for measuring a load occurring when transporting the medium while rotating the roll member 1/N rotations in a transport direction of the medium by driving the first driving unit while the second driving unit is stopped, and after executing the first process, executes a second process for rotating the roll member 1/N rotations in a opposite direction as the transport direction by driving the first driving unit while the second driving unit is stopped and then rotating the roll member 1/N rotations in the transport direction by driving the first driving unit and the second driving unit.
