<P>PROBLEM TO BE SOLVED: To provide a device and a method capable of detecting existence of an obstacle ahead in the advancing direction of a linear body, and applicable to linear bodies having various shapes or materials. <P>SOLUTION: In this measuring device, the flexure degree of the linear body 1 can be detected by a sensor 7 when the tip of the linear body 1 is brought into contact with the obstacle and a compressing force P is operated to the linear body 1 in the longitudinal axis direction. The detected flexure degree of the linear body 1 is converted into a compression force P in the longitudinal axis direction operating to the linear body 1, based on the previously determined correlative relationship between the flexure degree and the compression force. Thus, the existence of the obstacle ahead of the advancing direction of the linear body 1 can be detected by increase of the compression force. Furthermore, since the same measuring device can be applied to linear bodies 1 having various shapes and materials, high cost-performance can be obtained. <P>COPYRIGHT: (C)2008,JPO&INPIT |
