Claims (1)

[Scope of utility model registration request] On the sewing surface of the sewing machine, which has a sewing section formed by a sewing machine needle and a material presser foot, and a detection member for the front end of the fabric to be sewn is arranged on one side of the sewing section, the air is ejected from the sewing section forward of the sewing section in the fabric traveling direction. an air injection member for straightly advancing the sewing thread loop, the mouth of which faces directly toward the sewing section; a cutter that is perpendicular to the sewn fabric and for cutting the connecting portion of the sewing thread loop in the same fabric; a member for detecting the forward and backward ends of the fabric; Fabric conveying members that can be raised and lowered toward the sewing surface are arranged in the above-mentioned order and substantially in a straight line, and a suction holding and cutting section for the empty thread ring is arranged behind the sewing section in the direction of fabric movement. The suction holding/cutting section includes a pressing piece that faces the sewing section and is movable up and down, and is equipped with a cutter upper blade for cutting the thread empty ring suction section, and is supported by a spring and a pressing stopper in correspondence with the pressing piece. and a support piece that can be raised and lowered and has a lower cutter blade that corresponds to the upper cutter blade, and is located on the rear side of the pressing piece and the support piece and is arranged in parallel so as to be raised and lowered, and its suction opening directly faces the sewing part. 1. An automatic suture thread loop suction device comprising: a thread loop suction member having an orthogonal suction path;
