Abstract
In a recording medium transporting mechanism, a flange member is attached on either side of a roll paper and the flange member has a diameter smaller than a maximum outer diameter of a roll paper. Support rollers support a corresponding one of the flange members in a rotatable manner. The support rollers are moveable along the axis of rotation of the roll paper. The sum of an outer diameter of corresponding one of the flange members and the support rollers is greater than a maximum outer diameter of the roll paper. A rewinding roller of at least a length equivalent to a distance between both sets of support rollers when the sets of support rollers are farthest apart is engaged with a support roller within the set of support rollers and can rotate the flange member in a rewinding direction over a desired amount of continuous time.
