This embodiment is configured as described above.

The following is the knitting and replacement of the knitting yarns 8A to D, and the thread opening hole 2.
The effect of switching to 0 will be explained.

That is, as shown in FIGS. 2, 3, and 5, the knitting yarn 8A (others 8B to 8D may be used) is inserted into the yarn opening 20, and the knitting yarn 25 is inserted through the fixed yarn opening 24, and the knitting needles are inserted. By introducing the batts No. 2 into both the front and rear knitting paths Pi and P2 from each needle selection knitting preparation position, two-color simultaneous knitting can be performed according to a known method.

Further, by using the thread opening 20 and the rear knitting passage P2, well-known plain knitting, tuck knitting, pull-up knitting, etc. based on plain knitting can be performed.

Therefore, in order to replace the knitting yarns 8A to 8D with each knitting and replace them in the yarn openings 20, for example, the knitting yarns 8
To replace knitting yarn A with knitting yarn 8B, the carriage 10 is slid over the positions of the knitting yarn stoppers 6A-D to the opposite side for each predetermined course of the knitting (it is not necessary to move the carriage 10 Even if the entire yarn does not cross over to the opposite side, it is sufficient if the knitting yarn exchange yarn opening 16 crosses over to the opposite side).

As a result, the remaining three knitting yarns 8B, 8C, and 8D that have not been inserted through the yarn opening 20 are introduced from the opening groove 14, and then pass through the front side of the knitting yarn journal piece 18 and come into contact with the knitting yarn guide roller 23. (See Figure 7).

On the other hand, the thread 8A that has been inserted into the thread opening 20 is first deflected forward by the inclined surface of the knitting thread guide portion 19A of the protruding piece 19 at a portion immediately below the knitting thread stopper 6B, and then at the upright end. It is pulled out to the front side of the edge 19B (see Figures 6A and 6B).
Then, as the yarn opening 20 passes beyond the position of the knitting yarn stopper 6B, the portion of the knitting yarn 8A that is inserted through the yarn opening 20 is separated from the lower sloped edge 20B of the standing edge 19B. It comes off smoothly and immediately moves inside the introduction groove 21 to the entrance side thereof and comes into contact with the knitting yarn guide roller 23.

(See No. 7).

Next, as shown in FIG. 7, operate the operation button 9B to place the corresponding knitting yarn stopper 6B in the selected position, and also disable the knitting yarn stopper 6A that has been in the selected position. Can be retracted to selected position.

Subsequently, the carriage 10 is folded back and the knitting yarn stopper 6A-
By sliding the knitting yarn 8B back to the working knitting needle section side through the position D, the knitting yarn 8B selected at the selective position is captured by the knitting yarn journal piece 18 and introduced into the inlet 21 (FIG. 8A).
and FIG. 1), and then the knitting yarn 8B is made of
Due to the inclination of the tapered surface 22A and the rotation of the guide body 22, the yarn is smoothly and quickly guided into the thread opening 20 through the opening 20A (first
(See figure), before the yarn opening 20 reaches the end of the knitted fabric, the knitting yarn 8B is completely inserted into the yarn opening 20 over the upright edge 19B of the protruding piece 19.

(See Figure 9A and Figure 1). On the other hand, the other knitting yarn 8A is deflected forward from the lower side of the knitting yarn journal piece 18, and escapes to the outside of the carriage from the entrance through the opening groove 14 together with the other two knitting yarns 8C and 8D ( Figure 8 A-B and Figure 9 A-
(See B).

With the above steps, the knitting yarn exchange and replacement operation is completed.

Furthermore, the exchange and replacement of the other knitting yarns 8C and 8D can be performed in exactly the same manner.

In this case, by sliding the carriage 10 within the active knitting needle section after exchanging or replacing the knitting yarn, the knitting as described above can be performed. Yarn 8B (other knitting yarns 8A, 8G, 8
The same applies to D) is the tapered surface 22 of the dielectric 22.
Due to the inclination of A and the upright portion 19C of the protruding piece 19, the thread is held securely in the thread opening 20 and will not escape from the thread opening 20 into the introduction groove 21 in front.

Furthermore, since the guide body 22 rotates, the knitting yarn 8B is always fed out very smoothly and easily.

In addition, the yarn opening 20 can be used as a yarn opening for replacing knitting yarn as described above, and can also be used as a so-called ground yarn opening with the knitting yarn inserted through it at all times (the rear knitting passage P2 is mainly used (Applicable to knitting such as plain knitting and tuck knitting), in this case, the knitting yarns 8A-D are attached to the knitting yarn restraining body 6A in advance.
If the yarn is inserted into the thread opening 20 through the threads 6A to 6D, remove it from the knitting thread restraints 6A to 6D, and turn it from the lower side of the knitting thread guide 19A of the protruding piece 19 to its tip side. Just move it to the top.

(See Figures 10A and 11).

As a result, the knitting yarn replacement yarn opening 16 can be used in the same way as a normal yarn opening that is not replaced, and the knitting yarn inserted through the yarn opening 20 is inserted into the raised portion 1 of the protruding piece 19.
