Abstract
A transport device includes a transport belt configured to alternately repeat a transport operation of transporting a medium and a non-transport operation of not transporting the medium, a detection mechanism configured to detect a movement amount of the transport belt in the transport operation, and a control section configured to determine a magnitude of tension of the transport belt based on a vibration state of the transport belt when the transport operation ends, the vibration state being detected by the detection mechanism.
Claims7
A transport device comprising:
- a transport belt configured to alternately repeat a transport operation of transporting a medium along a transport direction and a non-transport operation of not transporting the medium;
- a detection mechanism configured to detect a movement amount of the transport belt in the transport operation and to detect a residual vibration of the transport belt by detecting a speed of the transport belt in a plus side and a minus side along the transport direction after applying to the transport belt a force or acceleration to vibrate the transport belt;
- and
- a control section configured to determine a magnitude of tension of the transport belt based on the residual vibration of the transport belt when the transport operation ends.
A transport device comprising:

- a detection mechanism configured to detect a movement amount of the transport belt in the transport operation and to detect a residual vibration of the transport belt by detecting a speed of the transport belt in a plus side and a minus side along the transport direction after applying to the transport belt a force or acceleration to vibrate the transport belt;
- a drive roller that is provided downstream of the detection mechanism in a transport direction in which the medium is transported, and that rotationally moves the transport belt;
- and
- a control section configured to determine a magnitude of tension of the transport belt based on the residual vibration between a plus side speed of the transport belt and a minus side speed of the transport belt detected by the detection mechanism.
A recording apparatus comprising:
- a recording section configured to record on a medium;
- a transport belt configured to alternately repeat a transport operation of transporting the medium along a transport direction and a non-transport operation of not transporting the medium;
