Abstract: A conveyance unit includes a feeding unit that feeds a medium from a roll, a conveyance roller pair that conveys the medium toward a printing unit, an intermediate roller pair that conveys, toward the conveyance roller pair, the medium fed by the feeding unit, a first driving unit that rotates a first driving roller, and a load changing unit that changes a pressing load acting between a second driving roller and a second driven roller. A control unit can execute a first control that controls the load changing unit such that the pressing load is a first pressing load when the first driving roller is rotated in an intermittent conveyance, and execute a second control that controls the load changing unit such that the pressing load is not generated when the rotation of the first driving roller is stopped in the intermittent conveyance.

Abstract: A printing apparatus includes a conveyance unit, a printing unit, and a control unit. The conveyance unit includes a feeding unit, a conveyance roller pair, a feed driving unit, a first encoder, and a second encoder. The control unit is configured to execute a feed adjustment operation of adjusting tension of the medium fed from the feeding unit by controlling the feed driving unit such that the control unit executes the feed adjustment operation based on an output of the second encoder in a first period from a start of rotation of the conveyance roller pair until a specified time elapses and such that the control unit executes the feed adjustment operation based on an output of the first encoder in a second period after completion of the first period.

Abstract: A medium feeding apparatus includes a feeding roller which feeds a printing medium, a roll holding portion which holds a roll body around which the printing medium is wound, an intermediate roller which pulls out the printing medium from the roll body and feeds the printing medium to the feeding roller, and a controller which synchronizes and controls driving of the feeding roller and the intermediate roller, in which the controller sets a target value in a driving control of the intermediate roller to be greater than a target value in a driving control of the feeding roller, so that tension is not applied to the printing medium between the feeding roller and the intermediate roller, when the feeding roller and the intermediate roller feed the printing medium.

Abstract: A recording apparatus includes an ink discharge part, a first drive part that drives a rotation of a roll body in which the recording medium is wound, a second drive part that drives the conveyance part that conveys the recording medium, and a control part that controls operations of the first drive part and the second drive part. The control part drives the first drive part in a halted state of the second drive part and executes a measurement that measures a relationship between a load and a drive speed when conveying the recording medium and the control part executes the measurement for a single rotation of the roll body. The control part also provides a first measurement mode to execute the single rotation which is divided into plural number.
