Reference numeral 30 is a drive arm pivotally attached to a carriage 21, which will be described later, and the rear part 30a is always pulled by a panel 32, and is ejected to the position shown by the two-dot chain line in FIG.

Therefore, the tip 30b of the drive arm 30 is pressed against the drive plate 28.

However, since the elasticity of the spring 32 is weaker than the elasticity of the operating shaft spring 17, the drive plate 28 does not retreat, but when the carriage 31 moves backward, the drive arm 30 rotates due to the frictional engagement between the drive arm 30 and the drive plate 28. Drive plate 2 at the position shown by the two-dot chain line in Figure 9.
8 is rotated to the position shown by the two-dot chain line, and the actuating shaft 13 is rotated, and then the driving plate 28 is returned to its original position by the elasticity of the actuating shaft spring 17, and the driving arm 30 reaches the position shown by the one-dot chain line.

The carriage 31 engages with the butt of the knitting needle 2 to give a lowering action, and the knitting needle 2 that engages with the needle selection recess 7b of the needle selection plate 7 and descends is passed through as it is, and the needle selection convex part of the needle selection plate 7 is passed through. A needle selection cam mechanism is provided for retracting the knitting needles 2 that are engaged with the knitting needles 7a and held in the upper position to the knitting waiting position.

This embodiment is configured as described above.

The effect will be explained below.

First, if a suitable manual operating member 18 is lowered from the position shown by the solid line in FIG. The signal board 21 is laterally moved to the right in FIG. 6 and becomes the state shown by the two-dot chain line.

Accordingly, the lowering plate 23 with the pin 23a inserted into the cam hole 21b of the signal plate 21 is lowered as shown by the two-dot chain line in FIG. 6, and the needle selection plate operating rod 8 is lowered.

In this case, the needle selection plate operating rod 8 is connected to the concave portion 11 of the operating rod rotating plate 11.
It is not in a position where it can engage with the plate spring 12, but remains in a position where it is pushed down against the elasticity of the leaf spring 12.

Next, the carriage 31 moves in the direction of arrow A in FIG. 9, then reverses and moves in the direction of arrow A, and then reverses and moves in the direction of arrow A.
If an attempt is made to move in the opposite direction, the drive arm 30 rotates due to the frictional action as described above, and the drive plate 28 retreats to the position shown by the two-dot chain line in FIG. It rotates to the position shown by the two-dot chain line in FIG. 1, and the operating shaft 13 rotates.

During this time, the rotating rod 14 rotates from the state shown by the two-dot chain line in FIG. 3 to the state shown by the solid line, and the rotating rod 14 and the operating rod rotating plate 1
The actuating rod rotating plate 1 due to the engagement with the cam hole 1lb of 1
1 is moved laterally from the position shown by the two-dot chain line to the position shown by the solid line in FIG.

In this position, the recess 11a of the operating rod rotating plate 11 is located below the needle selector plate operating rod 8, and the first
The needle selection plate operating rod 8 that has returned to the illustrated position and lowered is located in the recess 1.
1a.

Thereafter, when the carriage 31 moves forward and the drive arm 30 rotates to the position shown by the dashed line in FIG. , the rotating rod 14 returns to the position shown by the two-dot chain line in FIG.
The operating rod rotating plate 11 returns to the position shown by the two-dot chain line in FIG.
As the manual operation member 18 descends, the needle selection plate operating rod 8 inserted into the recess 11a is rotated.

Therefore, the needle selection plate 7 engaged with the needle selection plate actuating rod 8 moves laterally by half the pitch of the knitting needle row question interval, and the needle selection convex portion 7a is located below the knitting needles 2, and the needle selection plate 7 is not rotated. The needle selection plate 7 engaged with the operating rod 8 has the needle selection convex portion 7a located in the middle of the rows of knitting needles 2,
The needle selection recess 7b is located in the middle of the knitting needles 2.

If the carriage 31 is further advanced in this state, the needle selection cam mechanism applies a downward action to the butt of the knitting needle 2, and the knitting needle 2 that has been lowered by engaging the needle selection recess 7b of the needle selection plate 7 maintains the needle selection position. The knitting needles that are engaged with the needle selection protrusions 7a of the needle selection plate T and held at the upper position are moved back to the knitting waiting position, and after the carriage 31 passes, the knitting needles 2 are selected back and forth. .

Next, when attempting to select a needle by moving laterally in the needle selection mode, the bending portion 13a of the operating shaft 13 is rotated, the needle selection plate operating rod 8 is lowered all at once, and then the moving knob 24 is rotated. is rotated, and the sliding plate 19 is slid in the left-right direction by the meshing engagement between the gear portion 24a and the rack 25.

For example, if the lowered descending plate 23 (sixth, first
23P in Figure 0) is moved above the adjacent needle selection plate operating rod 8D.

Therefore, when the bent portion 13a of the operating shaft 13 is returned to the position shown by the solid line in FIG.
moves from the position shown by the one-dot chain line at the opening in FIG. 2 to the position shown by the two-dot chain line, and the knitting needle 2b adjacent to the knitting needle 2a selected in FIG. 2A is in a state of being selected.

Therefore, if the carriage 31 is then moved forward, the needle selection mode can be moved in the lateral direction and the needle selection can be performed.

As described in detail above, the present invention moves the connecting member together with the manual operation member in the direction in which the needle selector plate operating rods are arranged, and changes the engagement relationship between the connecting member and the needle selector plate operating rod. Since it is possible to move the pattern to a desired position in the knitted fabric in the same manner as it is, it has the effect of knitting.

Furthermore, in the device of the present invention, the number of needle selection plate operating rods may be the same as the number of needle selection plates, and the movement of the pattern can be achieved simply by appropriately setting the shape of the connecting member.
