Further, the needle selection rod 75 corresponding to the reader 27 in the second rotational position is prevented from moving downward integrally with the main body 67 due to the engagement with the flat portion 30 at the tip thereof, so that the main body 67 cannot be pressed down. Accordingly, it is retracted into the main body 67 and is held in an upper inactive position based on the engagement between the engagement protrusion 83 of the release plate 78 and the locking piece 75c of the needle selection rod 75.

When the pressing force on the main body 67 is released, the support member 88 holds the main body 67 in the standby position shown by the chain line in Fig. 3 and the solid line in Fig. 4. In this way, the needle arrangement signal of the needle selection card 17 is transmitted to the adjustable needle selector via the reader 27, and the needle selection rod 75 protrudes to the active position corresponding to the signal hole portion, and the needle selection rod 75 retracts to the inactive position corresponding to the non-hole portion. When the needle selection rod 75 engages with the flat portion 30 of the reader 27 and retracts to the inactive position, as is clear from Fig. 3, both 75,
Since the engagement position of 30 is behind the vertical straight line perpendicular to the rotation shaft 26, a clockwise moment acts on the reader 27, and there is no risk of a load being applied to the non-perforated portion on the needle selection card 17.

Next, insert the main body 67 of the adjustable needle selection tool into the needle selection tool insertion hole 1.
After taking it out from 0, the needle operation guide piece 84 is aligned with both ends of the template 93 and placed near the rear end on the groove plate 5, and both needle operation guide pieces 84 are joined on the groove plate 5. Then, the needle selection rod 75 at the operating position is engaged with the butt 2a of the knitting needle 2 placed at the knitting preparation position on the needle bed 1, and the needle groove engaging portion 7 of each needle selection rod 75 is engaged.
5a is engaged with the needle groove 5a. In this state, by moving the main body 67 forward to the knitting needle selection position, the knitting needles 2 can be easily and reliably sorted into the front needle selection position and the rear knitting preparation position. After first inserting the main body 67 of the universal needle selection tool into the needle selection tool insertion hole 10 and putting it in a standby state, for example, by sliding the carriage 40 from the right position to the left position in FIG. Pattern knitting can be performed based on the needle selection described above. At the same time,
The engagement piece 40a of the carriage 40 engages with the engagement portion 46 of the detection lever 43, and the detection lever 43 is rotated back and forth.

That is, as shown in FIG.
3, the first actuating plate 50 and the second actuating plate 61 are moved down together with the roller 51 by the action of the cam surface 47, and the notch 64 of the second actuating plate 61 moves the actuating shaft 37 downward. is rotated clockwise in FIG. 5, all the readers 27 are removed from the needle selection card 17, and are rotated to the second rotation position. Thereafter, only the first actuating plate 50 is moved downward, and with the extending portion 57b of the feed lever 57 pressed against the boss portion 20a of the ratchet wheel 20 by the spring force of the coiled spring 58, the claw portion 57a is latched. The ratchet wheel 20 is engaged with the root of the teeth of the etching wheel 20, rotates by one pitch, and is held in the rotated position by the cooperation of the leaf spring 23 and the gear 19. And this ratchet wheel 20
The needle selection card 17 is stage-advanced based on the rotation, and each reader 27 faces a new knitting needle arrangement signal.

When the detection lever 43 moves backward, only the second actuating plate 61 is moved upward together with the roller 51 by the action of the cam surface 47, and then the first and second actuating plates 50,
61 are moved upward in one piece. Then, when the second actuating plate 61 moves upward, the actuating shaft 37 is rotated back, and each reader 27 is sorted into the first or second rotating position based on the new knitting needle arrangement signal. Further, as the first actuating plate 50 moves upward, the claw portion 57a of the feed lever 57 is disengaged from the teeth of the ratchet wheel 20. Then, a new knitting needle arrangement signal is transmitted to the needle selection rod 75 of the needle selection tool main body 67 by the above-described pushing operation of the universal needle selection tool main body 67, and after the knitting needles 2 are selected by the needle selection rod 75, the carriage 40 By sliding to the right, you can knit the second row of patterns.

Therefore, by repeatedly pressing down the flexible needle selector, selecting the knitting needles 2 with the needle selector, and sliding the carriage 40 in one direction in that order, it is possible to reliably knit the unit pattern. In particular, the needle selection tool main body 6 can be inserted into the needle selection tool insertion hole 10 while it is on standby.
The needle selection card 1 is inserted from the front through the relief part 71a of 7.
The feeding status of the needle selection card 17 can be confirmed by visually observing the mark 17b of 7. In addition, in this embodiment, since the needle guide piece 84 is configured to hang down to a position slightly higher than the lower end of the needle selection rod 75 at the operating position, it is possible to accidentally insert the needle selection tool main body 67 when sorting knitting needles 2, etc. Even when pressed onto the groove plate 5, the needle selection rod 75 at the operating position is not erroneously retracted, and the needle selection rod 75, once selected, can be prevented from moving inadvertently. Furthermore, if it is desired to repeatedly display the unit pattern continuously, the templates 93 are installed in parallel on the groove plate 5 as shown by the chain lines in FIG. The knitting needles 2 can be sorted by the needle selection tool main body 67.

Another Example Next, another example of the indicator member will be described with reference to FIGS. 11 and 12. This indicator member 93 is made of a synthetic resin material, and has two needle grooves 5a adjacent to each other.
A substrate portion 96 having a substantially square planar shape that can cover a part of the needle groove 5a, and the needle selection tool main body 6.
A guide portion 97 is formed to protrude from the upper surface of the base plate portion 96 in order to guide the needle operation guide piece 84 of No. 7 onto the groove plate 5.
A pair of protrusions 98 are formed to protrude forward from the lower surface of the base plate 96 so as to extend in the front-rear direction at substantially the same intervals as the pitches of the needle grooves 5a.
It is composed of. A substantially V-shaped guide groove 97a is formed on the upper surface of the guide portion 97, the bottom of which slopes forward, and the ridgeline of the guide portion 97 converges at the bottom of the groove. In addition, a pair of protrusions 98
The width of the distal end is narrower than that of the proximal end, and the width of the needle groove 5 is narrower than that of the proximal end.
Both protrusions 98 are bent against their own elasticity when attached to a.

Therefore, when knitting is performed by repeatedly and continuously displaying unit patterns using this instruction member 93 based on the knitting needle arrangement signal of the needle selection card 17, the knitting needles 24
A plurality of indicating members 93 (for example, three) are attached near the rear end of the groove plate 5 at regular intervals. At the time of this installation, the proximal ends of the pair of protrusions 98 are engaged with the two adjacent needle grooves 5a with their tips raised, and then the tips of the protrusions 98 are engaged with the needle grooves 5a. When the tip is bent outward against its own elasticity, the groove plate 5 is clamped by its restoring force. In this state, the substrate portion 96 is attached to the groove plate 5.
By engaging with the upper surface of each indicator member 93, each indicator member 93 can be easily attached to the groove plate 5.

After sorting the needle selection rod 75 of the needle selection tool main body 67 into the working position and the non-working position as described above,
By engaging the needle guide piece 84 of the main body 67 with the guide groove 97a of the indicating member 93 and moving the main body 67 forward along the guide groove 97a as shown by the chain line in FIG. The guide piece 84 is joined to the upper surface of the groove plate 5, and the needle groove engaging portion 75a of the needle selection rod 75 in the operating position engages with the needle groove 5a.
The needle selection rod 75 reliably engages with the butt 2a of the knitting needle 2 at the knitting preparation position, and the knitting needle 2 can be moved to the needle selection position.

Effects As detailed above, this device has a pair of left and right parts on both left and right sides of the universal needle selection tool, the lower ends of which hang down to a slightly higher position than the lower end of the needle selection rod at the operating position, and which are joined to the upper surface of the groove plate. By providing the needle handling guide piece, when selecting knitting needles, a large number of needle selection rods sorted into a lower working position and an upper non-working position can be accurately corresponded to the butts of a predetermined group of knitting needles. These needle selection rods can be reliably guided to each vat, and the excellent effect of preventing the possibility that the selection state of the needle selection rods will be erroneously released is achieved.
