。 A detection needle is provided at the tip of a lever that is movable in the vertical direction near the front of the fabric at the end of the fabric, so that it can be freely displaced in the weaving direction, and at a predetermined timing, one end of the detection needle is brought into contact between the front and the back of the fabric. In a device for detecting the presence or absence of a weft thread after weft insertion, an analog sensor is attached to the lever at a position corresponding to the rear end of the detection needle, and the detection needle is urged by a spring in a steady state, The rear end of the detection needle corresponds to the analog sensor,
Furthermore, the weft thread detection device is characterized in that the output end of the analog sensor is connected to a comparator that compares the output signal of the analog sensor with a reference threshold value.
