Abstract
A rolled medium holding device includes a first gear mechanismthat is connected to a roll shaft holding the rolled medium and sends-out/rewinds the rolled medium, a second gear mechanismthat is connected to a torque limiterand includes a plurality of torque transmission means, and a gear switching mechanismthat shifts connection between the plurality of torque transmission means and the first gear mechanism by operating the second gear mechanism for applying different back tension to the roll shaft. Accordingly, torque transferred from the torque limiter can be shifted, and whereby back tension in correspondence with a used rolled medium can be easily applied in a simple manner.
