    • PURPOSE:To surely supply even a curled medium by providing a supplying roller for supplying stacked mediums so that it can freely float along the direction in which the mediums are stacked up, in compliance with the condition of the medium. CONSTITUTION:A medium 9 set in a device is supplied to the gate part by a supplying roller 3 driven through an electromagnetic clutch 1 by the power from a passbook-printing unit. In this case, the supplying roller 3 is composed of independent rollers 3a connected to each other by joint shafts 11, the respective rollers 3a are elastically supported by springs 12 attached to a base plate 10, and the respective rollers 3a can be displaced only downward in their places. By this constitution, when the medium 9 is curled, the supplying roller 3 can supply the medium 9 positively, because the rollers 3a are displaced downward in compliance with the curl.
