記載の織機の緯糸検出器。[Scope of Claim for Utility Model Registration] (1) A photoelectric reflection type weft yarn detector for a drum-type weft length measuring and storage device having a light emitter and a light receiver, which detects the incident angle of the detected light on the light receiving surface side of the light receiver. A weft detector for a loom, characterized in that it is provided with a pinhole that limits incident light and is set at the same angle as the loom. (2) Claim No. 1, characterized in that the pinhole is configured to converge toward the tip.
A weft detector for a loom as described in (1). (3) The incident light regulating portion defining and forming the pinhole is formed of a cylindrical body, and is formed as a flange-like member protruding from the inner wall surface of the cylindrical body toward the center. A weft detector for a loom according to claim (1) or (2).
