Alternatively, the knitting needles 2 that have engaged with the support protrusions 15a of the partial needle selection member 15 and are held in the upper position are moved back to the knitting time position, and the needle selection 2 that has descended without engaging with the needle selection protrusions 12a and the support protrusions 15a is moved back. This is a needle selection cam that allows the needle to pass while maintaining its position in the front and back direction.

Note that the actuating rods 10A and 10B can also be operated not by the signal holding member 5 but by a manual operating device such as a button or a lever via the manual operating plate 19.

This embodiment is configured as described above.

The effect will be explained below.

First, the activation plate 9 is manually operated from the solid line shown in FIG. The signal holding member 5 is inserted and wound around the drum 6.

Next, by returning the activation plate 9 to its original position, the actuation rod 10A
, B can be returned to the positions shown by solid lines in FIG. According to the block selection signal 5b, that is, depending on the presence or absence of a hole, the actuating rod 10B is similarly selectively arranged in the two positions shown by the solid line in FIG. 3 and the two-dot chain line. The operating rods 10A and 10B shown by the two-dot chain lines in FIG. The needle selection protrusion 12a is moved to a position where it is not located below the knitting needles 2), and the predetermined needle selection mode indicated by the pattern signal 5a of the signal holding member 5 can be sorted into patterns in which several sets are repeated. The preparation is made and at the same time the operating rod 10B
Only the partial needle selection member 15 that is engaged with R1 at the opening in FIG.
The support protrusion 15a is not located below the knitting needle 2.

In this case, the operating rod 10B in the position shown by the solid line in FIG. 3 is not rotated, and the partial needle selection member 1 engaged with the operating rod 1OB is not rotated.
5 is a knitting needle 2 which is held in a non-erasing position as shown in FIG.
Only 0 pairs can be selected.

That is, for example, as shown in the oral tradition shown in FIG. 5, in this case, only the T3 and T6 groups can be selected, and the others cannot be selected.

Next, when the carriage 16 is slid, the needle selection cam 18 applies a downward action to the pads of the knitting needles 2, and the pattern signal of the signal holding member 5 is applied only to the T3 and 75 sets of knitting needles 2, as shown by the opening in FIG. The height of the pad is generated in the needle selection manner instructed by 5a, and at the same time the pad is selected back and forth.

That is, the knitting needles 2a, which are supported by the needle selection protrusion 12a of the needle selection plate 12 or supported by the support protrusion 15a of the partial needle selection member 15 and cannot be lowered and are held at the upper position, retreat to the knitting time position, and the knitting needles 2a are moved back to the knitting time position, and the knitting needles 2a are held at the upper position, and the knitting needles 2a are held at the upper position because they are supported by the needle selection projections 12a of the needle selection plate 12 or by the support projections 15a of the partial needle selection member 15. Knitting needles 2 that are not supported by the support protrusion 15a of the partial needle selection member 15 in the set of knitting needles 2
Then, the needle selection 2b that is not supported by the needle selection protrusion 12a of the needle selection plate 12 and has descended is allowed to pass while maintaining its front and rear positions, so that only the T3 and 75 sets of knitting needles 2 are sorted and arranged in the front and rear.

Next, when reversing the direction of movement of the carriage 16, the swing plate 17
After activating the actuating member 4 to activate the activation plate 9 and converting the signal of the signal holding member 5 into a new signal, needle selection can be performed in the same manner.

In this way, needle selection for the A part of the signal holding member 5 shown in the first figure is performed for T3 sets and 75 sets of needles 2, and as a result, A1. After obtaining the pattern A2, needle selection for the B part of the signal holding member 5 shown in the first diagram is carried out in the same manner as described above, but as shown in the first diagram, the block selection signal 5b is T.
Since the instruction is to select only the needles of the 1st set, the T4 set, and the T7 set, Bl in the knitted fabric F, 827 as shown in the second diagram.
Obtain R3 pattern.

The needle selection device targeted in the above description can be replaced with another needle selection device.

For example, in this example, a needle selection cam provided on the carriage is used to sort the knitting needles back and forth while giving a downward action to the needles. may be formed into such a shape)
It is also possible to replace the knitting needle with a needle selection device that is equipped with a needle and that once sets the knitting needles at a height difference and then sorts them back and forth using a cam provided on the carriage.

Since the present invention is configured as described above, by combining the pattern signal and the block selection signal provided in the signal holding member,
Since a predetermined pattern can be placed at a predetermined position within the entire knitted fabric, it is possible to place the next part of the pattern on the knitted fabric after finishing knitting the part with the pattern, unlike conventional machines. This is very convenient since it is not necessary to carry out the complicated and troublesome operation of moving and arranging the indicating member for indicating the block of the block selection device after considering the above.
