Transportation apparatus and recording apparatus
A transportation apparatus includes a first velocity sensor that detects a first measure of the transportation velocity of a medium that is transported, and a second velocity sensor that detects a second measure of the transportation velocity of the medium. The first and second velocity sensors are positioned offset from each other in an intersecting direction that intercepts a transportation direction of the medium. A skew detection section calculates a velocity difference from the first and second measures of the transportation velocities, and determines a skew state of the medium on the basis of the velocity difference.
Printing apparatus and conveyance control method
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.
