Description of the invention (7) In this state, after pulling the operation lever 11 downward (direction of arrow C in the figure), as described above, the pre-pulling section 13 Slope right and move down in Figure 1. The line T is also induced to move simultaneously by the lifter 15. After the lifter 15 stops before exceeding the needles 2 and 3 of the sewing machine, the thread T is formed to be closed between the mounting substrate i3a of the pretension portion 13 and the pretension disk 13b. The tension is held with sufficient force to protrude. The state before the thread hole of sewing machine needle 2. At approximately the same time as the operation of the above-mentioned pre-tensioning portion 13 and the lifter 15, the threading shaft 21 rotates while descending, and the threading hook 25 gradually approaches the thread hole 2a of the sewing machine needle 2. When the wire T is formed to protrude before the wire hole 2a, by further rotation of the threading shaft 21, the threading hook 25 passes through the wire hole 2a, and the wire T is pulled by its hook-type tip and drawn into the wire hole 2a to form a coil. At this time, the leading end of the 'thread catching hook 26 is connected to the lower end of the sewing machine needle 2, and since it is bendable, it does not affect the bending of the sewing machine needle 2 as shown in Fig. 4b. After releasing the hand of the operation lever 11 in this state, the operation lever 11 rises as if returning. The threading shaft 21 gradually rises while rotating in the opposite direction, and with this movement, as shown in Fig. 4c, the threading hook 25 pulls the thread T away. At this time, the thread catching hook 26a is also separated from the sewing machine needle 2 and returned to the original shape. In addition, at approximately the same time, the space between the mounting substrate 13a and the pre-pulling plate 13b is opened, and the pre-pulling portion 13 and the lift rod 15 leave the line T and move diagonally upward to the original position. T is detached by the threading hook 25 by its own weight, but is caught by the thread catching hook 26a which is hung at an angle below the threading hook 25. Furthermore, the threading shaft 21 rotates and rises back to the original paper size. The Chinese national standard (CNS) A4 specification (210 X 297 mm) is applicable. — II · ---- Please read the precautions on the back before filling in this page ) Order ——line—t 10 Printed by the Consumers ’Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, and printed description of the invention (the standby position, the line catch hook 26a also returned to the original position, the line T was cut by a certain length The wire end passes through the wire hole 2a (Figure 4d). ------------- Installation—— (Please read the precautions on the back before filling this page) Also, the wire catch hook 26a, Since only the thread T is hung and not fixed, sewing can be started without the operation of removing by the thread catching hook 26a. If the thread T is pulled out from the thread hole according to the above threader device 10, the threading hook 25 is detached The thread is captured by the thread catching hook 26a. With the movement of the thread catching hook 26a back to the original position, since the wire end is pulled out from the wire hole, the wire end will not be detached on the way out. It can be sure Pull out through the thread hole. As a result, threading can be performed more simply and reliably. In addition, The elastic member 26 of the wire catching hook 26a is attached to the hook actuating plate 22 to constitute the threading hook actuating device 20, and the wire catching hook 26a is located below the threading hook 25 and is positioned in the front, so the edge follows the threading hook 25 The moving edge can reliably capture the thread T detached by the threading hook 25. Further, since the thread catching hook 26a is located directly below the threading hook 25 and is set so that its tip end is slightly near the tip of the threading hook 25 The front position, when the threading hook 25 pulls out the thread, it is finally connected to the sewing machine needle 2, but because it is a part of the elastic member, the side of the thread catching hook 26a retreating does not affect the sewing machine needle 2. In addition, The cutter 12 provided at a predetermined position under the side of the sewing machine arm 1 a can cut the thread T at the position where the thread is pulled out by the winding plate.
