Long medium

A long medium having a first side edge part and a second side edge part comprising:

• a plurality of holes equidistantly provided on a first straight line on the first side edge part in a longitudinal direction;
• at least one mark part provided on at least one of the first side edge part and the second side edge part;
• a plurality of first indicators equidistantly and repeatedly given to correspond with the first straight line;
• and
• a plurality of second indicators repeatedly given on a second straight line different from the first straight line at spacings shorter than spacings of the first indicators, the second indicators are each arranged between two of the first indicators;
• wherein
• rows of the plurality of holes, the plurality of first indicators, and the plurality of second indicators are provided approximately in parallel to each other;
• wherein a number of holes within the plurality of holes sectioned by adjacent ones of the first indicators together form a group, wherein the group comprises the adjacent ones of the first indicators and the number of holes within the plurality of holes between the adjacent ones of the first indicators, wherein a distance between a leading-end mark corresponding to a first one of the first indicators within the group and a trailing-end mark corresponding to a second one of the first indicators within the group indicates a reference length of the long medium, and
• the second indicators are each provided to a side of a corresponding trailing-end mark, and a respective one of the second indicators is positioned gradually closer than a previous one of the second indicators to the leading-end mark corresponding to the first one of the first indicators within the group that pairs up with the trailing-end mark corresponding to the second one of the first indicators within the group, as the long medium runs toward a trailing end.
