  • Transportation Apparatus and Recording Apparatus
    Publication number: 20160136977
    Abstract: 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.
