Abstract
PURPOSE: To facilitate the fitting adjustment at a machine production time by measuring the gap between the needle and the sword point quantitatively by an optical method.
CONSTITUTION: A uniform-intensity light is projected from light radiation side optical fiber 4. The passing light quantity having a certain relation to the value of gap g is incident onto light receiving-side optical fiber 5. Then, if receiving quantities for various values of gap g are previously found, gap g can be measured by measuring the receiving light quantity which incident onto light receiving-side optical fiber 5. However, light radiattion and light receiving optical fibers 4 an 5 have center axes arranged in parallel in one plane orthogonal to needle 2, and are supported by one attachment 6.
