<;P>;PROBLEM TO BE SOLVED: To provide a highly-accurate compressive force measuring device capable of quantifying a technique of a skilled operator, and transferring it to an unexperienced operator. <;P>;SOLUTION: This compressive force measuring device is equipped with a body 1 including a line sensor 7 for detecting the height h of a bend of a linear body 2, a semiconductor memory 9 integrated into the body 1 and storing a conversion table for converting a detection result by the line sensor 7 into a compressive force F, and a compressive force signal generation part 11 for generating a compressive force signal showing the compressive force F based on the detection result by the line sensor 7 and the conversion table stored in the semiconductor memory 9. Hereby, since the semiconductor memory 9 storing the conversion table is integrated into the body 1, the compressive force can be measured highly accurately, even when mechanical accuracy of the body 1 is low. <;P>;COPYRIGHT: (C)2008,JPO&INPIT
