This embodiment is configured as described above.

Below, a group of knitting needles in a specific range of the active knitting needle section (the 20 knitting needle section at the knitting preparation position I will explain the action.

That is, as shown in FIG. 4, the first rank plate 65 is supported on the moving body 35, and the first switching body 57 is fixed on the movable plate 54 in advance.

Further, the first rank plate 65 on the moving body is set to mesh with the upper gear 63 immediately before the sorting device on the rear side in the sliding direction of the carriage approaches the specific range, and this meshing is Until this is done, it is assumed that the holding portions 61 (A, B) on either the left or right side of the first switching body 57 are in a state in which all the rear actuating bodies 26 are pushed down to the non-driving position C. First, from a state in which the carriage 73 passes through the working knitting needle section and the moving member body 35 is rotating, for example, in the direction of the arrow shown in FIG. When the direction of movement of is changed to the direction opposite to the arrow shown in FIG. Then, a new needle selection operation signal sequence corresponds to the reading section 28 of the rear operating body 26.

Next, the carriage 73 approaches the working knitting needle section, and the first rank plate 65 on the moving body engages the upper gear 63 immediately before the sorting device 84 on the rear side in the sliding direction of the carriage approaches the specific range. The upper gear 64 is connected to the second switching body 5.
Move 7 horizontally.

Along with this lateral movement, the upward movement permitting portion 59B on the right side sequentially allows upward movement of the rear effecting body 26 toward the drive position a, starting from the rearmost actuating body 26 at the end. The rear actuator 26 that is allowed to move upward is divided into a drive position a and an intermediate position by the selection body 11, and only the rear actuator 26 that is divided into the drive position a is moved by the cam piece 3.
Driven by 3.

Furthermore, in synchronization with the driving and non-driving of each of the rear actuating bodies 26, the needle selection portion 7 of each corresponding needle selection body 6 locks or does not lock the reduction knitting needle 2. The 20 knitting needles that are locked are sorted forward, and the 20 knitting needles that are not locked are sorted backwards.

In this way, the right upward movement permitting portion 59B is connected to the rear operating body 2.
By sequentially allowing upward movement from the left end to the right end of the needles 6, a group of knitting needles (12 needles) in a specific range is selected.

After the selection action is completed, as the first switching body 57 continues to move to the right, its intermediate holding portion 61C sequentially pushes down each of the rear operating bodies 26 to the non-driving position C. Since the rear operating body 26 is separated from the selection body 11 and the cam piece 33 of the circulation drive body 31, each needle selection body 6 is placed in the needle selection non-operating position during this time, so that the selection A predetermined number of knitting needle groups following the right side of one specific range of knitting needle groups are not selected.

Next, as the first switching body 57 continues to move to the right, the left upward motion permitting section 59A sequentially permits each rear operating body 26 to move upwardly, thereby causing the right upward motion permitting section 5
By the same action as in the case of 9A, following on the right side of the non-selected knitting needle group (another specific range knitting needle group (12 needles))
A sorting action is performed.

As described above, each rear actuating body 26 is cyclically driven from one end 26 to the other end 26 only when corresponding to the left and right upward movement permitting parts 59A, 59B of the first switching body 57. The knitting needles are sequentially driven and undriven by the body 31, and the non-selected part consisting of a predetermined number of knitting needles is sandwiched in the middle, and each of the 12 knitting needles on the left and right sides is
A selection action is performed in a specific range of three locations on the left and right consisting of the Motoki-ni knitting needle group.

When this knitting needle sorting action is completed, the first rank plate 65 comes off from the upper gear 63 and the upper gear 630 stops rotating, and the first switching body 57 moves to the left holding part 61A.
stops at the position where all the rear effecting bodies 26 are pushed down to the non-drive position C.

Furthermore, when the carriage 73 is folded back and slid to move the moving body 35 in the opposite direction, the first rank plate 65 engages with the upper gear 63 from the opposite side, and the second switching body 57 moves in the reaction direction, and as a result, in the same manner as described above, the knitting needles 2 in the two left and right specific ranges consisting of the 12 knitting needle groups on the left and right respectively move to the opposite end. The items are selected sequentially.

However, in order to perform the knitting needle selection function in a specific range consisting of a group of knitting needles (12 needles) with a smaller number of needle selection cycles than the specific range described above, the first switching body 57 and the first rank plate 6
5 with the second switching body 70 and the second rank plate 71 (this can be done in substantially the same manner as described above).

As detailed above, the present invention includes a plurality of needle selection members,
Targeting a needle selection device that is provided with a plurality of actuating bodies that are classified by a needle selection operation signal of a selection body, a circulating drive body, and a sorting device, the needle selection device is particularly targeted at a needle selection device that is provided with a plurality of actuating bodies that are classified by a needle selection operation signal of a selecting body, a circulating drive body, and a sorting device. The operating portion is displaceable between a drive position driven by the circulation drive body and a non-drive position where it is not driven, and is provided so as to be movable in the arrangement direction of the circulation drive body and replaceable. , and a plurality of switching bodies whose movement allows each of the acting parts to move freely to the drive position in a certain order and change the number of times the moving parts are allowed to move freely, and the moving body is paired with each of the switching bodies, respectively. a plurality of driving bodies that are replaceably provided in connection with the moving body and that are respectively movable with the moving body; The switching body is provided with an interlocking connection body that operatively connects the switching body and the driving body.

Therefore, by replacing the switching body and driving body that have been set in advance with another set of switching bodies and driving bodies, knitting needles in a specific range of continuous knitting needles of the same number as the number of needle selection operation signals in one row of the selection body can be set. It is possible to select needles by changing the number of units, with each group as one unit.

That is, as in the above embodiment (for example, switching between a state in which only a group of knitting needles in one specific range is selected and a state in which each group of knitting needles in two specific ranges is respectively selected), This allows for accurate pattern knitting.
