  • Patent number: 10982366
    Abstract: A sewing machine includes a controller and a thread cutter which cuts an upper thread passed through a sewing needle and which has a fixed knife, a moving knife, and a driving source to drive the moving knife. The moving knife cuts the upper thread by guiding the upper thread. The moving knife has a through-hole into which the sewing needle is loosely insertable and includes a thread cutting portion in an inner edge portion of the through-hole. By controlling the driving source, the controller makes a stitch point of a first stitch of the sewing needle with respect to the through-hole of the moving knife, and moves the moving knife to a position where the fixed knife and the moving knife cut a sewing start end portion of the upper thread after a stitch point of a second stitch of the sewing needle.
