As shown in the organization chart in Figure 15, side A from the left end,
They are set and connected in the order of F, H, E, A, F, H, E, A, F, and constitute the heald body 3 together with the pattern dial 5. Then, among the dial numbers 5a, 5b, 5c, . . . . When the weft thread 8 is passed through the spaces between the threads 7 and 7, a cloth 9 with a pattern as shown in Fig. 15 is woven. 6"-"8"-
"4"
- Fabrics 9 with various patterns can be woven by passing the weft threads 8 between the warp threads 7...7 while setting the dial numbers in the number set section in the order of a predetermined pattern such as "2". It's getting old.

[Problem that the invention attempts to solve]

However, in the conventional loom toy mentioned above, the dial numbers from "1" to "8" had to be set in the number setting section by turning the heald body 3 by hand each time, which caused the following problems. It was hot.

(1) It is troublesome to turn the heald body 3 and set a predetermined dial number in the number setting section each time the weft thread 8 is passed between the warp threads 7...7, and it is difficult for children who do not understand numbers to operate it. It may not be possible.

(2) For example, "4" - "2" - "8" - "6" - "8"
−
If you are weaving fabric using a dial number pattern of ``2'', even if you currently set the number ``8'' in the number set section, is this ``8'' just before ``6''? , or "2"
Sometimes I forget if it was just before that.

The present invention has been made for the purpose of solving the above-mentioned conventional problems.
