Abstract
A transport device includes a transport roller configured to transport a roll paper, a winding unit configured to wind the roll paper transported, a tension applying unit configured to apply tension to the medium between the transport roller and the winding unit, and a control unit configured to control the tension applying unit. The control unit is configured to control the tension applying unit to maintain a state where the tension is released, at least during an acceleration period of rotation of the transport roller within a period in which the transport roller applies a transporting force to the roll paper.
Claims8
A medium transport device comprising:
- a transport roller configured to transport a long medium;
- a winding unit configured to wind the medium transported;
- a tension applying unit configured to apply tension to the medium between the transport roller and the winding unit;
- and
- a control unit configured to control the tension applying unit, wherein
- the control unit is configured to control the tension applying unit to maintain a state where the tension is released, at least during an acceleration period of rotation of the transport roller within a period in which the transport roller applies a transporting force to the medium, and
- wherein during a winding operation where the winding unit winds the medium, the control unit is configured to control the tension applying unit to maintain a state where the tension is applied to the medium.
A recording method using a recording device including
- a transport roller configured to transport a long medium,
- a winding unit configured to wind the medium transported,
- a tension applying unit configured to apply tension to the medium between the transport roller and the winding unit, and
- a recording unit configured to perform recording onto the medium,
- the recording method comprising:
- controlling the tension applying unit to maintain a state where the tension is released, at least during an acceleration period of rotation of the transport roller within a period in which the transport roller applies a transporting force to the medium;
- and
- controlling the tension applying unit to maintain a state where the tension is applied to the medium during a winding operation where the winding unit winds the medium.
