Thereby, the conveyance speed of the web W is controlled to be constant.

  Further, the transport controller 26 calculates the output torque of the transport motor 55 according to the current supplied to the transport motor 55. The output torque of the carry motor 55 can be calculated from the motor characteristics of the carry motor 55 according to the supply current. The unwinding device controller 13 adjusts the braking force of the brake 12 so that the difference between the output torque of the conveyance motor 55 calculated by the conveyance controller 26 and the output torque of the brake 12 becomes a target torque difference corresponding to the target tension of the web W. Adjust the output torque. Thereby, the tension of the web W is controlled to be constant.

  When the printing of the image is finished, the ink circulation controller 29 of the printing apparatus 3 finishes the ink circulation operation by the ink circulation unit 24. Further, the unwinding device 2, the printing device 3, and the winding device 4 end the conveyance of the web W. Specifically, the unwinding device controller 13 stops the brake 12, the transport controller 26 of the printing device 3 stops the transport motor 55, and the winding device controller 93 stops the winding motor 92. Thereby, a series of operation | movement is complete | finished.
