Description of the invention ((Principle. First, as described above, the “stitch 9 is fixed by one way that is swung leftward beyond the baseline by the above-mentioned needle swing mechanism with a baseline mechanism. Therefore, when the needle 9 is lowered to two positions on the left and right sides” The baseline position fixed by the baseline mechanism is the right needle down position, while the needle 9 is fixed by the needle swing mechanism 42 with the baseline as the reference point and swings left by one needle swing amount to the left needle drop position. That is, Fig. 60 shows the details of the sutured dense thread part to the middle part in Fig. 54 (3). The right needle drop point & is above the baseline ', unless the baseline is relative to the right needle drop point n. ] And changed a needle swing amount Ηι which can be determined by the needle swing mechanism 42, otherwise the left needle drop point h will be above the left side. However, if the left needle drop point is set to h, the baseline moves K3 to the right, the needle will The amount of swing must ensure that the left needle drop point 112 is Hi + KD. Moreover, when the left needle drop point becomes the next needle drop point η ', its position can be judged by setting the baseline. In other words, since the baseline moves from the needle drop point to the baseline to the right by an amount of K3, the baseline position moved by K3 itself is the needle drop point η3. Similarly, when the right needle drop point η becomes the next left needle drop point ~, the amount of needle swing from the baseline (from the needle drop point to the baseline, move to the right and back ^ is Shi Shi !! # !!,! ^. 3 Furthermore, when the left needle drop point η becomes the next needle drop point, if the baseline moves, the baseline position itself provides the paper size under the needle applicable to the Chinese National Standard (CNS) A4 specification ( 210 X 297) A7 B7 V.
