A compression spring 193 wound around the armatures A1 and A2 between the bracket 90 and the bracket 94 allows
Each attraction portion 190 is urged to move in a direction away from the electromagnets S1 and S2. As shown in FIGS. 20a and 20b, when both or one of the electromagnets S1 and S2 are excited by a predetermined electric signal, they resist the spring force of the compression spring 193 and attract each armature A1 and A2. The portion 190 is the electromagnet S1,
S2 attracts the locking piece 191, and the locking piece 191 separates from the U-shaped proximal end of the auxiliary needle operating lever 147, and each armature A1, A2 is placed in a non-engaging position. In addition, as shown in FIGS. 20b and 20c, the electromagnet S1,
When one or both of S2 is de-energized, the locking piece 191 is projected toward the proximal U-shaped portion of the secondary needle operating lever 147 based on the spring force of the compression spring 193,
Each armature A1, A2 is placed in an engaged position.

Furthermore, as is clear from FIGS. 18a and 18b, FIGS. 19a to 19c, and FIGS. , A2 hanging piece 19
2 and the secondary needle operating lever 147 is placed at the upper limit position by the action of the cam surface 182b, each armature A1, A2 is temporarily moved to the non-engaged position against the spring force of the compression spring 193. are arranged in a row. In this state, as shown in FIG. 21, the excitation states (ON-OFF states) of the electromagnets S1 and S2 are determined according to various knittings performed by one main needle 4.

For example, in back stitch knitting, when both electromagnets S1 and S2 are excited with the secondary needle operating lever 147 placed at the upper limit position, as shown in FIG.
As shown in FIG. 2, the armatures A1 and A2 are held in the non-engaged position by suction, and as the moving member 181 moves leftward, the secondary needle actuating lever 147 is placed in the lower position. Therefore, the cam contact pin 147a is engaged with the fourth drive cam 143 as shown by the chain line in FIG. Furthermore, when only one electromagnet S1 is energized during the lying down position, one armature A1 is placed in the non-engaged position and the other armature A2 is placed in the engaged position, as shown in FIG. 20b, and the armature A2 is moved. When the auxiliary needle actuating lever 147 is lowered to the intermediate position as the member 181 moves leftward, the U-shaped proximal end of the lever 147 touches the armature A2.
The lever 147 is held in that position. Therefore, the cam contact pin 147a is engaged with the fifth drive cam 144 as shown by the chain line in FIG.

Furthermore, for example, during table knitting, both electromagnets S

As shown in the figure, each armature A1, A2 is placed in the engagement position by the spring force of the compression spring 193, and as the moving member 181 moves leftward, the secondary needle operating lever 14 is moved.
7 is slightly lowered from the upper limit position, the U-shaped proximal end of the auxiliary needle actuating lever 147 engages with the armature A1, and the lever 147 is placed and held in the upper position. Therefore, the cam contact pin 147a separates from the fourth and fifth drive cams 143 and 144, as shown by the solid line in FIG.

Next, regarding the related structure of the electromagnet S3, the shape and structure of the armature A3 attracted by this electromagnet S3 and its supporting structure are shown in FIG.

3 is placed at the upper limit position, and the leaf spring 18
4, the armature A3 is temporarily placed and held at the non-engaging position. In this state, for example, when the electromagnet S3 is energized to move the carriage 8 to the left and perform table stitching, the armature A3 is attracted and held in the disengaged position as shown in FIG. 19b. As the moving member 181 moves to the left, the yarn feeder actuating lever 163 is placed in the lower position. Therefore, as shown by the chain line in FIG. 22, the cam contact pin 163b is engaged with the seventh drive cam 160 on the upper surface of the second cam ring 111. Furthermore, when the carriage 8 is moved to the right and the electromagnet S3 is not energized to perform table stitching, the armature A3 is placed in the engagement position by the spring force of the compression spring 193, as shown in FIG. 19c. As the moving member 181 moves leftward, the U-shaped proximal end of the yarn feeder actuating lever 163 engages with the armature A3, and the yarn feeder actuating lever 163 is disposed at the upper position. Therefore, as shown by the solid line in FIG. 22, the cam contact pin 163b is engaged with the eighth drive cam 161 on the lower surface of the first cam wheel 110.

As shown in FIGS. 3 and 16a and 16b, the electromagnets S7 and S8 are attached to the rear lower surface of the bracket 94. As shown in FIG.
