8 and the signal reading members 14.14a interlocked via each reading/scanning member 10.10a have a click action.

Sometimes, each of the signal reading members 14.14a is arranged at different positions in the front and back in the vicinity of the reading parts 18, 18a at each inner end thereof, for example, in the vicinity of the reading part 18 on the right side. Afterwards, the vicinity of the left side reading part lea is placed in front, and the above-mentioned cross line 17 is drawn on the front face of the right side part, and the above-mentioned cross line 17a is also drawn on the rear face of the left side part (the operator In order to reduce the reading error between the right and left sides even if the height of the stitches changes to some extent), the pitch related to the gauge of the number of stitches on the side of the movement direction of each signal reading member 14.14a Abbreviation - Add the display line (display part) 56°56a that indicates the stitch length, for example, if the general stitch number gauge is 40 stitches, 80771771 to 1
Since it changes within the range of 80wn, the length pitch of the first stitch (3,
25 mm), draw the slightly thinner display line 56 at a position left and right away from the central intersection (reading part 18° 18a) of each cross line 17.17a, intersecting the horizontal line of each cross line. .

When using this device, the signal display member 5 displaying the desired knitting work type 6 to be knitted is wound around the sprocket wheel 9, and then the gauge of the number of stitches per stitch and the number of rows per row is determined by trial knitting or by experience. Based on the determination, the stage feed pitch of the signal display member 5 is determined, and the length value of the number of stitches (40 stitches) corresponding to the predetermined movement amount ratio is determined by the number 52 of the display scale 51. The dial 44 is rotated as shown in (at this time, the operating shaft 47 is of course lowered).

From this point, each knitting needle indicating member 19 is moved by each bundle 21 on both sides (hereinafter, only one number is shown), and each knitting needle indicating portion 20 is arranged so as to be closest to each other at the center in the longitudinal direction of the needle bed 1. Then (Fig. 7), all the knitting needles 2 on the needle bed 1 are pushed and displaced against the action of the spring 3, and each knitting needle butt reaches a lower position where no knitting movement is applied by the cam of the carriage. At this time, the reading section 18 of each signal reading member 14 is adjusted so that it coincides with the intersection P between the base line 0-0' of the knitting work pattern 6 and the center line.

Specifically, the signal reading member 14, which can be moved independently by pushing down the operating shaft 47 and the distance between the trochanter 35 and the disk 32, is operated by a finger rest engraved on the member 14. Each reading section 18 is moved to the original position until it coincides with the intersection point P, and then the operating shaft 47 is returned.

Next, the respective knitting needle indicating members 19 are moved by each bundle 21, and the reading section 18 of each signal reading member 14 interlocked therewith is located at the position of the left and right outer points 0, 0' of the base line 0-0'. When the knitting needles are moved until they approach or match at the outer position, the respective knitting needle designating portions 20 are read by the reading unit 18 to indicate the knitting needles 2 of the number of stitches included in the outer line of the knitting work pattern 6 between the base line 〇 and 〇′. The pressure on the knitting needles 2 is released, and the elastic force of the needles 3 returns them to their original upper positions, and the knitting needles 2 that are unnecessary for other knitting
Continuing to press on point a, the knitting needle 2 corresponding to the position 0.0' of the above-mentioned outline line is clearly indicated by the upper and lower steps of each knitting needle butt.

As described above, the number of knitting needles 2 necessary for set-up is automatically determined, so knitting yarn is supplied to these knitting needles 2 to proceed with the set-up operation, and then the leash course is knitted by sliding the carriage. Each time the work is done, the sprocket wheel 9 rotates, and the wheel 9 feeds the signal display member 5 in stages at a constant feeding pitch that matches the pitch in the direction of the number of stages.
At that time, if the outlines of each reading section 18 and the knitting work pattern 6 do not match, each time the bundle 21 interlocks the knitting needle instruction member 19 and the signal reading member 14 so that the reading section 18 always matches the outline. Perform the following operations.

In this way, the respective knitting needle indicating portions 20 are interlocked to clearly indicate the knitting needle 2 corresponding to the position of the above-mentioned outline line with the upper and lower steps of the knitting needle butt, and this is the end of the group of knitting needles that should participate in the formation of the knitted fabric. It clearly appears as a knitting needle in the section (Fig. 8).

At this time, when the signal display member 5 is advanced, the intersection of the reading portions 18 as shown by the solid line in FIG. 9 points to the outline of the knitting work pattern 6, If the state changes as shown in , it is easy to understand that the change in the position of the outline line is so slight that it does not come far from the display line (display part) 56, that is, the change in the knitting width. - It's so small that it's less than the length of the eye.
It is clearly understood that this does not require any operation of increasing or decreasing the number of knitting needles.

Therefore, only when the change in the position of the outline approaches or exceeds the display line 56, the bundle operation is proceeded to confirm the increase or decrease in the number of knitting needles.

Therefore, when the position of the outline line changes, it is not necessary to unnecessarily repeat the operation of the bundle 21 just because the position has changed, and it is easy to determine whether or not the bundle operation is necessary using the display line 56 as a guide. The molding operation can be carried out quickly.

Therefore, the knitting needles that have been lowered to the lower position by the pressure of each of the knitting needle indicating portions 20, that is, the knitting needles 2a that do not need to participate in the formation of the knitted fabric, are not moved back to their expected knitting position. Even if the hook remains in the position behind the sinker, the knitting yarn will not get caught in the hook, so knitting work type 6
There is no problem in forming a knitted fabric that follows the pattern (If there is an increase or decrease in the knitting needles, you can knit a fabric in the desired shape by simply increasing or decreasing the stitches as necessary.) can do.

As explained above, the present invention particularly refers to the left and right outlines of the knitted work type on the signal display member, and is provided with a pair of signal reading members equipped with reading parts that read the positions of the left and right outlines separately. and a pair of knitting needle indicating members that indicate the knitting needles on the needle bed corresponding to the positions of the left and right outline lines in relation to the reading movement thereof, further comprising: Since the member is provided with a display section that displays at least approximately the length of the stitch at intervals from each reading section on the side in the movement direction, each knitting section is determined based on the approximate length of the stitch on the display section. Accurately grasp the amount of change in the position of the outline of the knitting work pattern for each row feed, judge whether the amount of change affects the increase or decrease of the knitting needles, and eliminate waste when the amount of change is minute. By omitting the operation of signal reading instructions, the molding operation can proceed easily and quickly.

Furthermore, since the reading portions and the display portions are provided in the reading portions arranged at different positions before and after each of the signal reading members, the display portions on the sides of the reading portions in the moving direction are mutually connected to each other. For example, the left and right reading parts can be precisely aligned with the center line of the knitting work pattern without worrying that the reading parts cannot be aligned accurately due to interference, and the setting operation at the beginning of molding can be performed. It has excellent practical effects, such as being able to very clearly indicate which knitting needles are needed for the set-up and which ones are not, without causing any hindrance to the process, allowing for more accurate forming operations. have.
