All of the butts are introduced into the back butt guide passage 18 for knitting the back stitches without being affected by the action of knitting, so that knitting of flat knitting can be performed.

Next, a case will be described in which so-called garter stitch, in which front stitches and back stitches are knitted alternately in each row, is performed without using the signal card 124.

First, move the switching cam 126 on the carriage 6 to the third position.
The main needle 2 within the knitting section on the needle bed 1 is placed in the knitting preparation position, and the main needle 2 outside the knitting section on the needle bed 1 is placed on the underside of the carriage 6. It is arranged at a position corresponding to the needle rest passage 19. Next, a pair of cam pieces (not shown) are placed on the rear edge of the needle bed 1 so as to correspond to the two main needles 2 located outside of the two main needles 2 at both left and right ends of the knitting section. do. Next, when the operation piece 154 is rotated and placed in the position shown in FIG. 11a, the second sensing member 136 and the needle sensing member 137 are moved to the position shown in FIG. It is placed in the non-sensing position shown in b. Meanwhile, the first sensing member 135 is placed at the sensing position shown in FIG. 11d.

In this state, when the direction switching plate 72 is placed at the rear switching position shown in FIG. 6, the rotating member 84 is rotated via the pin 84a, and one end of the rotating member 84 is turned to It is separated from one sensing piece 141. When each of the cam wheels 30 to 32 is rotated, the butt 2a of the rightmost main needle 2 in the knitting section is introduced into the butt operating body 12. Also, drive cam 1
34 low cam portion 134a is the arrangement changing member 130
When facing the cam follower piece 133 of the leaf spring 138
Due to the spring force, the first sensing member 135 and the repositioning member 130 are placed in the lower position shown in FIG. 4, and the first sensing piece 141 projects into the needle rest passage 19. Therefore, the switching plate 96 is placed at the rear position (second position) shown in FIGS. 4 and 5.

In this way, the rotating member 84 is connected to the first sensing piece 141.
In the state where the main needle 2 is separated from the main needle 2, the same cam selection state as in the case where the butt 2a of the main needle 2 is not detected by the needle sensing member 137 is set.
Through the cooperation of the rightmost main needle 2 and the counter needle 48, the front stitch can be knitted, and by continuing to rotate each cam wheel 30 to 32 in this state, the carriage 6 is moved to the left. Accordingly, it is possible to knit one row of front rows.

On the other hand, after the above-mentioned knitting is completed, when the linking pin 86 of the rotating member 84 shown in FIG. 3 engages with the left cam piece (not shown) on the needle bed 1, the rotating member 84 is It is rotated in a predetermined direction, and the end of the first sensing piece 141 is covered by the rotating member 84, and the direction switching plate 72 is moved forward via the pin 84a. As a result, the arrangement position of the rotary lever 80 is changed, and the biasing direction of the shaft 65 by the coiled spring 81 is switched to the right. When each of the cam wheels 30 to 32 is subsequently rotated, the carriage 6 is now moved to the right, and the butt 2a of the main needle 2 at the leftmost end of the knitting section is introduced into the butt operating body 12. Then, the lower cam portion 134a of the drive cam 134
3, the downward movement of the first sensing piece 141 is blocked by the rotating member 84, so the spring force of the wire spring 131 causes the position changing member 130 to be separated from the upper surface of the carriage 6, creating a wide space between them. A gap is formed.

In this case, since the switching plate 96 is moved to the forward position through the gap, the same drive cam selection state as when the butt 2a of the main needle 2 is detected by the needle sensing member 137 is set. Therefore, the back stitch can be knitted using the leftmost main needle 2, and then the carriage 6 is moved to the right by rotating each cam ring 30 to 32, and the back stitch is knitted to the next row of the front row of the one row. You can knit a row of back stitches.

After this knitting is completed, the rotating member 84
When the linking pin 86 engages with the right cam piece (not shown) on the needle bed 1, the rotating member 84 is rotated in a predetermined direction by the cam action, and the end thereof is separated from the first sensing piece 141. They are separated, and the first sensing piece 141 is allowed to move downward. As a result, the above-mentioned front knitting state can be set again, and as the carriage 6 moves leftward, one row of front knitting can be performed again on the next row of the one row of back rows. can.

It should be noted that the present invention is not limited to the above-mentioned embodiments, and the configuration of each part can be arbitrarily changed and embodied without departing from the spirit of the invention.

Effects of the Invention As detailed above, the present invention eliminates the need to sort the knitting needles on the needle bed by hand or with a manual handle plate in advance to separate front stitches and back stitches, and as the carriage moves, This provides an excellent effect in that the needle selection operation and knitting operation can be performed automatically and continuously.
