摘要

PROBLEM TO BE SOLVED: To provide a feeding device of a roll-shaped recording medium, a printing device of the roll-shaped recording medium, a remaining amount derivation device of the roll-shaped recording medium, a remaining amount derivation method of the roll-shaped recording medium, and a program, in which the remaining amount of the roll-shaped recording medium is properly derived by a simple method while preventing damage to the roll-shaped recording medium.SOLUTION: A feeding device 1 of a roll-shaped recording medium includes: holding means 8 for rotatably holding the roll-shaped recording medium; first unrolling control means for rotating a rotating shaft of the holding means 8 by a first rotational speed and unrolling the roll-shaped recording medium when a first condition is satisfied; second unrolling control means for stopping unrolling, or rotating the rotating shaft of the holding means 8 in the second rotational speed and unrolling the roll-shaped recording medium when a second condition is satisfied; transfer means for transferring the unrolled roll-shaped recording medium; and derivation means for deriving the remaining amount of the roll-shaped recording medium on the basis of an elapsed time after the first condition is satisfied before the first condition is satisfied next, or the elapsed time after the second condition is satisfied before the first condition is satisfied next.
