，５Ａ，５Ｂ，３５を配設し、受光器４の受光量
に基づいて緯糸検知回路１４，４４により緯糸の
検知を行うようにした織機の光電式緯糸検知装置
において、前記緯糸検知回路１４，４４とは別に
、前記受光器４の受光量を所定レベルと比較しそ
のレベルの範囲外のときに異常信号を出力する異
常検知回路１８，４５を設けたことを特徴とする
織機の光電式緯糸検知装置。 A translucent cover 5 is placed in front of the emitter 3 and receiver 4.
, 5A, 5B, 35, and the weft detection circuits 14, 44 detect the weft based on the amount of light received by the light receiver 4. 44, the photoelectric weft of a loom is characterized in that an abnormality detection circuit 18, 45 is provided which compares the amount of light received by the light receiver 4 with a predetermined level and outputs an abnormal signal when the amount of light received by the light receiver 4 is outside the range of that level. Detection device.
