A release button 18 is located in the center hole of the spring take-up shaft 17 so that the wound spring can be released. If the length of the yarn used is taken up by using the amount of the spring involved, the volume of the spring is increased. From the viewpoint of miniaturization, the amount of winding of the spring is smaller than the length when used. For example, the length of the thread to be used is 20 m, while the winding amount of the spring is 6 m. Therefore, when the yarn is fed out by 6 m, the winding of the spring becomes full, and it is not possible to feed the yarn any further. In such a case, the spring is released. Then, a further 6 m of yarn can be pulled out. When the 12 m yarn is unwound in this way, the 6 m yarn can be wound by the force of the spring, but the remaining 6 m is wound by rotating the spring winding shaft 17. Such a spring mechanism, for example,
As described in Japanese Utility Model Publication No. 55-10067, the structure is well known, and a detailed description of the structure will be omitted.
