Apparatus for detecting the irregularities on the surface of a linear material. |
| 摘要 |
<p>An apparatus for detecting any irregularities on the surface of a running linear material is proposed which has a light projector and a pair of photoelectric conversion elements. The shadow of the material is cast on the elements. By picking up a difference between the outputs from the elements, any irregularities can be detected.</p> |
