Abstract:
1. A medium carrying device, comprising: a first carrying part that carries a medium to a first position; a second carrying part that is positioned on a downstream side of the first carrying part; a medium carrying detection part that detects stoppage of carrying the medium; a slack detection unit that is positioned between the first carrying part and the second carrying part and includes a sensor that is configured to detect presence of a slack in the medium after a medium carrying operation of both of the first carrying part and the second carrying part has stopped but before resuming the medium carrying operation of the first and second carrying parts; and a controller that: stops the medium carrying operation of both of the first carrying part and the second carrying part based on the detection of the stoppage of carrying the medium by the medium carrying detection part, while the first carrying part and the second carrying part are operated to carry the medium, for resuming the carrying of the medium thereafter, determines which one of the first carrying part and the second carrying part should resume the medium carrying operation first based on the presence of the slack in the medium that is detected by the sensor of the slack detection unit after the medium carrying operation of both of the first carrying part and the second carrying part has stopped but before resuming the medium carrying operation of the first and second carrying parts, and resumes the medium carrying operation of a determined one of the first carrying part and the second carrying part, wherein the controller controls the slack detection unit to detect the presence of the slack in the medium while the medium carrying operation of both of the first carrying part and the second carrying part has stopped as a result of the detection of the stoppage of carrying the medium by the medium carrying detection part.
