Abstract
The transport control section performs, in a case where a first motor and a second motor are driven so as to transport a long sheet to the downstream side in a transport direction, prescribed processing that is different from the processing in a case where the deflection amount of the sheet becomes equal to or greater than a reference amount, in a case where the deflection amount of the sheet between a shaft member and a sending roller in the transport direction does not become equal to or greater than the reference amount.
Claims14
A transport device that transports a long medium so as to send the medium downstream in a transport direction by rotating a shaft member on which the long medium is wound in a roll form, the transport device comprising:
- a sending roller that is disposed further downstream in the transport direction than a housing section where the medium wound in a roll form on the shaft member is housed, the sending roller feeding the medium downstream in the transport direction;
- a driving section that generates driving force for rotating the shaft member and the sending roller;
- a detection section that detects a deflection amount of the medium between the shaft member and the sending roller in the transport direction;
- and
- a control section that controls, when transporting the medium downstream in the transport direction, the driving section such that the deflection amount of the medium detected by the detection section becomes equal to or greater than a predetermined reference amount,
- wherein when the driving section is driven so as to transport the medium downstream in the transport direction, the control section performs prescribed processing that is different from when the deflection amount becomes equal to or greater than the predetermined reference amount when the deflection amount of the medium detected by the detection section does not become equal to or greater than the predetermined reference amount.
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.
A recording apparatus comprising:
- a transport device that transports a long medium so as to send the medium downstream in a transport direction by rotating a shaft member on which the long medium is wound in a roll form;
- a recording section that is disposed further downstream in the transport direction than the sending roller and which attaches fluid to the medium;
- and
- a cutting section that is disposed further downstream in the transport direction than the recording section and which cuts the long medium after the fluid is attached to the medium,
- wherein the transport device includes:
- a sending roller that is disposed further downstream in the transport direction than a housing section where the medium wound in a roll form on the shaft member is housed, the sending roller feeding the medium downstream in the transport direction;
- a driving section that generates driving force for rotating the shaft member and the sending roller;
- a detection section that detects a deflection amount of the medium between the shaft member and the sending roller in the transport direction;
- and
- a control section that controls, when transporting the medium downstream in the transport direction, the driving section such that the deflection amount of the medium detected by the detection section becomes equal to or greater than a predetermined reference amount,
- wherein when the driving section is driven so as to transport the medium downstream in the transport direction, the control section performs prescribed processing that is different from when the deflection amount becomes equal to or greater than the predetermined reference amount when the deflection amount of the medium detected by the detection section does not become equal to or greater than the predetermined reference amount.
