長する像2Aを常時捕捉する。Additionally, as the vertical width of the marker m2 increases, the vertical width of the image 2A also changes, so the vertical component photoelectric converters (P, Q) of the light receiving block 10 detect this rate of change, and in order to cope with this change, the vertical width of the image 2A changes. The output signal from the light receiving block 10 (P, Q) is sent to the motor M, and the shield plates (5, 6) are relatively opened to constantly capture the image 2A whose vertical width is expanded.
このようにして、引張試験が行われ、上部の標線2と下
部の標線2との標線間距離が測定せしめられる。In this manner, a tensile test is performed, and the distance between the upper and lower gauge lines 2 is measured.
