摘要： PURPOSE:To perform readjustment positioning highly accurately, by repositioning a moving table on a carrier so that a positional error caused during the movement of the carrier is compensated by a measuring stage. CONSTITUTION:For example, when a moving table 26b is sent by a measuring stage 47a and a light shielding plate 27 comes to a position, where a specified amount of light is shielded with respect to a light sensor 53, the moving table 26b is stopped. The position of the moving table is precisely determined with respect to the light sensor 53. The light sensor 53 is arranged at the same position as the light sensor at a set stage, i.e., at the position, where the tip of an optical fiber to be measured is suitably aligned with an output end 57 and an input end 58 on the side of a measuring device. Therefore, the position deviation of the moving table 26, which is caused by the positional error between a carrier 25b and a guide rail 55, can be compensated. That error is caused during the movement of the carrier 25b from the set stage 46 to the measuring stage 47a.
摘要翻译：目的：通过在载体上重新定位移动台，使载体运动过程中产生的位置误差由测量台补偿，可以高精度地进行重新调整定位。构成：例如，当测量台47a发送移动台26b并且遮光板27到达相对于光传感器53屏蔽规定量的光的位置时，移动台26b停止。移动台的位置相对于光传感器53精确地确定。光传感器53被布置在与光传感器相同的位置处于设定阶段，即在光纤的尖端到被测量与测量装置一侧的输出端57和输入端58适当地对准。因此，可以补偿由载体25b和导轨55之间的位置误差引起的移动台26的位置偏差。在载体25b从固定台46移动到测量台47a的过程中引起该误差。
