Abstract

A device 21, for optoelectrically detecting a portion 20 on a sliding clasp fastener chain 13 while it is moving along, comprises means for generating a signal in response to a reduction in the amount of light caused by the portion 20 switching means 23 for generating a signal in response to reception of the signal, and control means 25 for stopping motor 24. The pulses received by the phototransistor 28 as a result of the fastener portions interrupting the light 26 are insufficient to actuate a thyristor 31. This is actuated when the portion 20 intervenes, the portion being adhesive tape holding down the fastener element ends. <IMAGE>
