たことを特徴とする緯糸検知装置。 In a waterjet type loom, there is a feeler head that is provided integrally with the reed and detects the weft when the reed moves forward, an amplifier that linearly amplifies the yarn signal from this feeler head, and a 2-bit or more digital signal that converts the yarn signal from this amplifier into a 2-bit or more digital loom. An analog/digital converter for converting into a signal, and determining whether at least a part of each digital signal from the analog/digital converter falls within a certain range each time the reed moves forward. 1. A weft yarn detection device characterized by comprising: determination means for determining the presence or absence of a weft yarn.
