Abstract
This invention relates to a coupling condition detecting device for element rows of a slide fastener. A chain stopping means for stopping a chain at a detecting position of coupling right and left elements adjacent an upstream end of a space in the chain is disposed downstream along a chain carrying direction. A detecting portion having a mechanical detecting means for detecting presence/absence of a deviation in coupling of the elements is provided at the detecting position. The detecting portion has an element position detection member movable between a normal first contact position where the detection member does not contact any elements and an abnormal second contact position where it contacts an element. When the detection member exists at the first contact position when the chain is stopped, it is determined that the coupling is normal and when the detection member exists at the second contact position, it is determined that the coupling is abnormal.
