At that time, the pin 55 engages with the pin 24 of the activation plate 17 and the spring 2
3, the activation plate 17 is rotated from the solid line shown in FIGS. 2 and 7 to the two-dot chain line shown in FIGS. Therefore, due to the engagement between the pin 17a of the activation plate 17 and the cam hole 28c of the moving member 28, the moving member 28 moves from the state shown in FIG. 11 to the indicated state in FIG. The cutting groove 28a of the moving member 28 corresponds to the lower part of the plate operating shaft 25, and the needle selection plate operating shaft 25
becomes possible to fall. After that, the shaft 22 is lowered, and all needle plate operating shafts 25 are lowered against the elasticity of the leaf spring 26.
The state is shown by the two-dot chain line in FIGS. 2 and 7. Therefore, the tip 25a is separated from the needle selection card 10. Next, if the operation part 52a of the switching plate 52 is removed from the locking part 54a,
The activation plate 17 returns to its original position due to the return elasticity of the spring 23, and the sliding shaft 52 also returns to its original position.

Accordingly, the shaft 22 returns to its original position, and the needle selection plate operating shaft 25 corresponding to the hole 10a, which is the signal for needle selection on the needle selection card 10, returns to the position shown by the solid line in FIGS. 2 and 7 by the leaf spring 26. It engages with the fixing member 29. The needle selection plate 27, which engages with the needle selection plate operating shaft 25 through the vertically elongated hole M, has its needle selection protrusion 27a positioned below the knitting needle 2, as shown in FIG. However, the needle selection plate operating shaft 25, which does not respond to the fogging needle signal 10a of the fogging needle card 10 and is prevented from rising, remains below the position shown by the two-dot chain line in FIGS. When the moving member 28 moves leftward from the state shown in FIG. 11 to the state shown in FIG. 11, it is rotated by the groove 28a. The needle selection plate 2 engages with the needle selection plate operating shaft 25 through the longitudinal hole M by the rotation.

The rotation operation plate 5 is controlled by the switching lever 59 of the carriage 56.
8 in a position where it does not contact the actuating member 4, and the carriage 56
, the knitting needle 2 is moved forward to the needle selection position by the raising cams 61 and 61', and then moved to the needle selection position by the raising cams 61 and 61'.
' and the auxiliary cams 64, 64', when the needle selection protrusion 27a of the needle selection plate 27 is located downward (operating position), its descent is prevented and the needle selection protrusion 27a moves along the needle selection cams 63, 63'. When the protrusion 27a moves backward and reaches the knitting standby position, and the protrusion 27a is not located downward (inactive position), the key needle cams 63, 63' descend.
It will pass through as it is and reach the needle selection position.

Next, in order to perform needle selection while rotating the needle selection card 10 as the carriage 56 slides, first, the cutting lever 59 is
By switching the rotary operation plate 58, the rotation range is limited to a position where the engaging portion 58a of the rotary operation plate 58 is always in contact with the actuating member 4, and the carriage 56 is moved to the first position.
When moving in the direction of arrow A in the figure, the engaging portion 58a engages with the square hole of the actuating member 4, thereby moving the actuating member 4 to the position shown by the two-dot chain line in FIG. 2, the activation plate 17 is rotated as shown by the two-dot chain line in FIG.
After the moving part village 28 moves from the state shown in FIG. 11 to the state shown in FIG. 11 due to the engagement between the shaft 22 and the cam hole 28c, all the needle selection plate actuating shafts 25 are lowered by the shaft 22 and the tips thereof are lowered. 25a is pulled away from the needle selection card 10, and further the activation plate 1
7 rotates, and the engagement between the inclined portion 17 and the pin 33 causes the feed rotary plate 32, the feed plate 34,
The feed pawl wheel 15 is fed by one pitch via the feed pawl 37, and the signal of the needle selection card 10 is converted.

After that, when the carriage 56 is further advanced, the rotary operation plate 58 rotates as shown by the dashed line in FIG. Return to the position shown by the solid line in Figure 7, and needle selection card 10
The needle selection plate 27 is placed in the working position and the non-working position as instructed by. Thereafter, the knitting needles 2 are selected by the needle selection cams 63, 63' in the same manner as described above. This process can be repeated one after another to transfer the needle selection card 10 and select needles. Next, when performing partial needle selection, operate the operating part 48c of the partial needle selection plywood 48 to move the partial needle selection plywood 48 laterally and move the moving shaft 49. Position the crab.

Here, explanation will be given assuming that it is located in the mouth. As mentioned above, the pattern erasing plate S is removed by the engagement between the pin Q and the cam hole 50c.
2 is moved to the position shown by the solid line in FIG. 5, and the other pattern erasing plates 6, , S8, S4, and S5 remain in the inactive position as shown by the two-dot line in FIG. Therefore, the needle selection part 50a is the total needle 2
It is located below the set of T2 in the needle selection mode, and the erasing part 50b is located below all the other knitting needles 2. In this state, assuming that the needle selector plate 27 is now placed in the operating position with the thread aligned as shown by the two-dot chain line in FIG. 5, if the carriage 56 is slid,
All the knitting needles 2 are pressed downward by the needle selection cams 63 and 63', but only the green needle whose lower surface is not supported by the T silk needle selection plate 27 descends, and all other sets of knitting needles 2 are erased. Part 50b
It cannot be lowered because its lower surface is supported by (see Figure 5).

Therefore, only the green needle 2 of the L set is selected. Further, by laterally moving the partial needle selection plywood 48 and moving the moving shaft 49 to any position on the table 6, A to E, the needle selection mode T. An appropriate set can be selected from among the fine needles of ~T5, and only that fine needle can be selected. Since the present invention is configured as detailed above, it is possible to select one of several sets of needle selection modes by simply moving an appropriate one of the plurality of pattern erasing boards, each of which has a needle selection section and an erasing section, to the operating position. It is possible to select only the set of needle selection modes corresponding to that loose needle part, and the other coarse needle selection modes corresponding to that erased part can be made not to be selected, and the needles can be selected over the entire width of the knitted fabric. It is convenient whenever a pattern is desired partially without a pattern, and furthermore, the structure is simple and it can be produced at low cost.
