Claim:
1. A transportation apparatus, comprising: a first velocity sensor located at a first position to detect a first transportation velocity of a medium as it is transported in a transportation direction; a second velocity sensor to detect a second transportation velocity of the medium as it is transported in the transportation direction, said second velocity sensor being located at a second position offset from the first position in a spanning direction intersecting the transportation direction; a skew detection section that calculates a velocity difference between the first transportation velocity and the second transportation velocity, and detects a skew state of the medium on the basis of the velocity difference; a skew correction execution section that executes skew correction for the medium on the basis of the skew state detected by the skew detection section; and a transportation section that transports the medium intermittently; wherein the skew correction execution section executes the skew correction on the basis of a tendency of a change in the velocity difference when the medium is transported by the transportation section.
