When moving in the direction, the test piece 1 is pulled in the arrow D direction.
Therefore, the marked line 2 moves from the initial position while the length of the marked line 2 is being expanded, so that the standard tracking device 8 also moves in the arrow mark E direction in response to the movement. Further, since the vertical width of the image 2A also changes with the extension of the vertical width of the marked line 2, the vertical component photoelectric converters (P, Q) of the light receiving block 10 detect this change rate and respond to this change. Therefore, the light receiving block 10 (P,
Image output from Q) is sent to the motor M, the shield plates (5, 6) are opened relatively to block light from other than the image 2A, and the image changes with the extension of the vertical width of the marked line 2. 2A is projected on the light receiving block 10. In this way, the tensile test is performed, and the distance between the marked lines 2 between the upper marked line 2 and the lower marked line 2 is measured.
