Claims (1)
ることによって得られる受光素子の出力信号の変化分の
みを積分し、積分値が所要の糸切れ検知用基準レベル以
下となったときに糸切れを検知する光電検出器において
、糸の振動範囲内の２以上の個所を通過する光を投射す
る投光部と、上記各個所を通過する光をそれぞれ受光す
る２以上の受光素子とを備え、２以上の受光素子が並列
接続され、各受光素子の出力信号が１つの積分回路に入
力することを特徴とする糸切れ検知用光電検出器。Integrates only the change in the output signal of the light receiving element obtained when the light projected by the light emitting element is periodically blocked by the vibrating thread, and when the integrated value falls below the required standard level for thread breakage detection. A photoelectric detector for detecting thread breakage includes: a light projector that projects light that passes through two or more locations within the vibration range of the thread; and two or more light receiving elements that receive light that passes through each of the locations. A photoelectric detector for thread breakage detection, characterized in that two or more light receiving elements are connected in parallel, and the output signal of each light receiving element is input to one integrating circuit.
