PROBLEM TO BE SOLVED: To simultaneously measure a pulled-out length of a sheet material in parallel with work for pulling out the sheet material from a roll body, to perform the length measurement within a narrow space, and to bring the measuring instrument in a compactly housed and collected state when preserving or carrying a measuring instrument.SOLUTION: A pulled-out length measuring instrument A is configured to measure a pulled-out length when pulling out a rolled sheet material B from a roll body (b) for a required length and cutting the sheet material B away. The pulled-out length measuring instrument A comprises: an instrument body 1 in which the roll body (b) is supported in a rotatable manner; and a measuring implement 2 which is mounted in the instrument body 1 and brought into contact with the sheet material B pulled out from the roll body (b) to measure, integrate and display the pulled-out length of the sheet material B. |
