所に設けられている。One end of a support body 12 is pivotally attached to the slide body 8 by a short shaft 13, and the support plate 12 is counterclockwise in FIG. 2 (arrow A direction) by a spring member 14 wound around the pivotal attachment portion. Since it is biased to rotate, the projecting engagement portion 15 provided toward the threading base 6 side is pressed against the surface of the threading base 6. On the other end of the support plate 12, a threading guide 17 is rotatably supported by a short shaft 16. The threading guide has a V-shaped engaging lever 18 at the upper end.
Is formed, a protruding locking portion 19 is formed at a position substantially the same as the protruding engaging portion 15 of the support plate 12 toward the threading base 6 side, and further slightly below the locking portion. A small protrusion 20 is provided at the position of, and an expansion spring 22 is provided between the bent portion 21 of the support plate 12 on the rear surface above the short shaft 16 and at the lower end. A lateral positioning portion 23 (see FIG. 4) brought into contact with the side surface of the trunk of the needle 3 and the thread hole 4 of the needle
The thread receiving portion 24 formed at the tip toward the pressing operation portion at the other end
25 by means of the spring 26, the fourth on the front side in FIGS.
In the figure, the thread insertion piece 27 is always pressed in the direction of arrow C.
A thin elastic member that guides the side surface of the lateral positioning portion 23 to contact the needle 3 and hooks the thread protruding ring inserted into the thread hole from one side of the needle to hook the thread onto the needle. A hook-shaped thread pull-out piece 28 drawn out to the other side, and a thread guide slanted portion extending laterally at the lowermost end and at the back.
A protrusion 32 in which 31 is formed and a thread groove 33 for placing the thread across the path through which the thread receiving portion 24 formed at the tip of the thread insertion piece 27 passes when the thread insertion piece 27 is pushed out are provided. There is. Further, the sliding body 8 is lowered by an operation to move the threading derivative.
When the tip of the thread insertion piece 27 attached to the lower end of 17 reaches the position where it coincides with the thread hole of the needle, the locking piece provided on the sliding body 8
A switch 35 that is pressed by the 34 and turned on is provided at an appropriate position on the arm machine frame.

の糸穴４への挿入可能な状態にセットされる。Since the present invention has the above-mentioned structure, when the sewing machine is stopped near the top dead center of the needle bar, the operating portion 9 of the threading device is lowered (in the direction of arrow B in FIG. 2). The sliding body 8 is lowered on the threading base 6, and the support 12 pivotally attached to the sliding body 6 and the threading guide 17 are also lowered. When the projecting engagement portion 15 and the projecting locking portion 19 that are pressed down against the threading device 6 from the support and the threading guide are disengaged from the threading platform 6, the spring member 14 and the expansion spring 22 act. Further, it rotates counterclockwise and abuts against the side portion of the needle bar 2 so that the descending contact with the stopper pin 37 is stopped. When the threading guide 17 is lowered to this position, the side surface of the lateral positioning member 23 of the threading guide 17 is brought into contact with the side portion of the needle 3 by sandwiching the needle 3 with the pull-out piece 28, and the thread inserting piece 27 is removed. The needle is set so that it can be inserted into the thread hole 4.

糸穴４に挿入せしめられる。When the sliding body 8 is lowered in this state, the switch 35 arranged on the arm machine frame is pressed by the locking piece 34 of the smooth surface portion 10 to be turned on. When the switch 35 is pressed, it causes the lighting device 36 to light up and sends a threadable signal to the operator. When the operator confirms that the signal has been output, he presses the pressing operation section 25 of the threading device, and the tip of the thread insertion piece holds the thread and inserts it into the thread hole 4 of the needle.
この後糸通し誘導体17を針から外すと前記引き出片28の
フック部に糸が掛けられて糸は完全に針に通される。After that, when the threading guide 17 is removed from the needle, the thread is hooked on the hook portion of the pull-out piece 28 and the thread is completely passed through the needle.
（効果） 本考案は以上の如き構造及び作用をなすものであるか
ら、糸通し装置が糸掛け操作部９の操作により下降せし
められて針の糸穴４に対して糸挿入片27が適正な位置に
なると点灯装置が点灯されるので操作者は点灯を確認し

糸穴に的確に挿入されて糸を通すことが出来るものであ
り、実用的効果大なものである。(Effect) Since the present invention has the above-described structure and operation, the threading device is lowered by the operation of the threading operation section 9 and the thread insertion piece 27 is properly inserted into the thread hole 4 of the needle. When the position is reached, the lighting device is turned on, so if the operator confirms the lighting and then presses the pressing operation part 25 of the thread insertion piece 27, the tip end is accurately inserted into the thread hole of the needle and the thread can be threaded. It has a large practical effect.
尚、前記点灯装置をブザー等音声発信装置に換えても同
様の効果を有することは云うまでもない。Needless to say, the same effect can be obtained by replacing the lighting device with a voice transmitting device such as a buzzer.
