摘要： A printer includes a supply shaft wound with unused film including contrast agent, a winding shaft wound with used film including used contrast agent, rotation-speed detector for detecting a rotation speed of the supply shaft, and remaining-amount detector for determining an amount of unused film from the detected rotation speed detected. In the printer, the remaining amount of unused film such as ink film, roll paper or the like can be determined accurately.
