<p>A device for inspecting the grooves of a spiral spacer for carrying optical fiber having spiral grooves formed in the outer peripheral surface thereof, comprising a groove defect detection part having rotating bodies rotated according to the running of the spacer for carrying optical fiber and detecting the groove defect of the spiral grooves for slidable contact from the rotating resistance of the first rotating body and a groove pitch measuring part detecting the groove pitch of the spiral grooves from the rotating angle of the second rotating body and the running speed of the spacer for carrying optical fiber, the groove defect detection part further comprising a linearly extending guide rail, a supporting member slidably installed on the guide rail, the first rotating body rotatably supported on the supporting member, and a load detector connected to the supporting member through a magnetic attracting means moved separately from and closely to the supporting member when a force more than a specified value is applied to the supporting member.</p> |
