PROBLEM TO BE SOLVED: To provide a mono gauge that uses a printable plastic material for improving inherent disadvantages caused by a material and a manufacturing method and can measure a length, an inner diameter, and outer shape of an object with a gauge.SOLUTION: In a tabular material where scale is printed, the outer shape thereof has a shape that becomes a rectangle and whose corner parts become arcs, and the inner shape thereof has an intersection, a semicircle connecting isosceles extension lines, and a substantially ellipse formed of a semicircle at the intersection. A portable mono gauge in which the inner shape and the outer shape are easily removable in the same shape can measure an inner diameter, an outer diameter and a length of an object with the single gauge. |
