A relatively long coil holding member in the form of a coil must be provided, and when the yarn holding member is attached to the yarn supporting plate, the yarn supporting member is provided by notching the yarn supporting plate, and the coil-shaped end portion is provided. Since it is pierced and fixed to the thread support plate, the structure for holding the thread extending from the thread spool becomes complicated and the production cost becomes high.

Further, in this spool stand, the thread holding member is provided near the thread spool, and the thread extending from the thread spool is directly
In other words, in order to hold the thread without threading it in the guide hole, every time the thread is changed, the thread extending from the thread spool to be used must be threaded in the guide hole. Since it is necessary to hang the thread, it is complicated, and the thread changing operation becomes very troublesome.

In the spool stand disclosed in Japanese Utility Model Publication No. 60-6050, a thread stopper having a pair of thread stoppers is provided, and a plurality of thread holders are formed on the pair of thread stoppers, respectively. Since a plurality of engaging claws and the like for attachment to the second guide member are also formed on the thread stopper, the structure for holding the thread extending from the thread spool is very complicated and the production cost is high. become. Also, as in the above-mentioned publication, the guide hole must be threaded with both hands and threaded, which is complicated. In addition, since the guide member is formed in a strip shape and has low strength, there is a problem that, for example, when an operator places a hand near the end of the guide member set in the horizontal direction, the guide member is easily broken.

From 2 the thread can be hooked on the guide portion 21 very easily. Since the thread holding section 30 has the substantially inverted T-shaped mounting section 31, the O-ring 32 can be easily mounted on the mounting section 31.

Since the square tube member 41 of the leg portion 6 is hollow, the weight of the spool stand 1 can be further reduced, and various parts such as spare parts, The members can be stored.

A modification of the above embodiment will be described. 1) Only the guide member 3 may be arranged alone near the sewing machine, that is, the guide member 3 may be used without the support member 2 or the like. 2] In the guide member 3, a plurality of thread holding mechanisms 5 may be provided on the band plate member in which the plurality of guide portions 21 are omitted.

3) Instead of the O-ring 32, various ring-shaped rubber bodies can be applied. 4) Instead of the arrow mark “←”, the direction indicator may be various figures. For example, in FIG. 7, an arrow including a thread hooking procedure described below the thread holding mechanism 5 may be used as the direction indicating unit. In this case, the threading procedure can be understood more clearly. Further, the direction indicator may be provided with a sticker of a graphic such as an arrow mark or a sticker on which the sticker is printed.

5] The cross-sectional shape of the rectangular cylindrical member 41 and the connecting cylindrical portions 42 and 43 to which the upper and lower ends of the rectangular cylindrical member 41 are inserted and connected are various polygons such as a triangular shape, a rectangular shape, and a base shape.

According to the spool stand of the eighth aspect, the same effect as that of the seventh aspect is obtained, but since the guide member extends in the length direction thereof and the thick portion is provided between the guide portion and the thread holding portion. The strength of the guide member can be increased. For example, even if an operator places his / her hand near the end of the guide member set in the horizontal direction, the guide member is unlikely to break, and the thread extending from the guide portion is not easily broken. Since the middle part can be pressed against the thick part with a finger, it becomes easy to carry out the work of holding the yarn extending from the thread spool in the yarn holding part.

According to the spool stand of the ninth aspect, the same effect as that of the eighth aspect is obtained, but since the guide portion has the thread introduction opening facing the opposite side to the thick portion, it extends from the thread spool of the support portion. Even when the yarn is held with one hand, the yarn can be hooked from the yarn introduction opening to the guide portion very easily.

According to the spool stand of claim 10,
The same effect as in claim 8 or 9 is achieved, but since the guide member has a plurality of guide portions and a plurality of thread holding portions corresponding to these guide portions, the plurality of guide portions guide the yarn extending from the thread spool. In addition, the yarn can be held by the yarn holding portion.

According to the spool stand of claim 11,
The same effect as any one of claims 4 to 10 is obtained, but the thread holding section has a substantially inverted T-shaped mounting section in a side view, and between the elastic member mounted on the mounting section and the thread holding section. The structure for holding the thread extending from the thread spool can be simplified because the thread is held by the thread, and the elastic member made of a ring-shaped rubber body or the like can be easily mounted on the mounting section of the thread holding section. Is possible, and the production cost can be reduced.

According to the spool stand of the twelfth aspect,
An effect similar to that of the eleventh aspect is obtained, but since the elastic member is an O-ring, an existing O-ring can be applied as the elastic member, which is very advantageous in cost.
