Patent ID: 8777363

Claim:
A transport method that transports a long medium so as to feed the medium downstream in a transport direction by rotating a shaft member on which the long medium is wound in a roll form, wherein a sending roller rotates in order to feed the medium downstream from a housing section where the shaft member is housed, the sending roller being disposed downstream from the housing section, the method comprising: performing rotation control so as to rotate the shaft member and the sending roller such that the deflection amount of the medium between the shaft member and the sending roller in the transport direction becomes equal to or greater than a predetermined reference amount; and performing prescribed control such that, while the shaft member and the sending roller are rotating so as to feed the medium to the downstream side in the transport direction, when the deflection amount of the medium does not become equal to or greater than the reference amount, prescribed processing is performed that is different from when the deflection amount becomes equal to or greater than the reference value, wherein rotation control is performed using a driving section that generates: a first driving force that rotates the sending roller and the shaft member in a first rotational direction so as to transport the medium downstream in the transport direction; and a second driving force that rotates the sending roller and the shaft member in a second rotational direction that is a direction opposite to the first rotational direction, so as to wind the medium on the shaft member.
