PURPOSE:To print the making line length in the position according with the measured length by printing on a marking cable in order at a printing part provided on the circumferential surface responding to an electric signal of a rotation amount of a measuring tape role. CONSTITUTION:A length marking device 1 includes a measuring means 3, which has a marking cable 2 between a belt driving part 30A and a guide role 33 for outputting a measured amount of the marking cable 2 as a rotary angle signal 38 and a pulse signal emitting means 4 outputting a pulse signal 4A responding to the rotary angle signal 38 every unit rotary angle. The constitution also includes a printing means 5, which converts this pulse signal 4A into a rotary angle signal 5B while driving a printing roller 20 to stamp a line length mark on the marking cable 2. While measuring the length of the marking cable 2, the line length is printed on the marking cable 2. Thereby, the stamp line length can be printed in the position according with the measured length on the marking cable. |
