Reference numeral 30 denotes a left-right moving plate, which stands up an operating pin 30a, brings it into contact with the cam portion 28a of the operating cam 28, and causes the operating pin 30a to move left and right depending on the uneven shape of the cam portion 28a.

Reference numeral 31 denotes a connecting link which is rotated in conjunction with the left and right moving plate 30 to rotate left and right cam operating plates 32 and 33.

Reference numeral 34 indicates a path changing cam, which is an example of various cams for knitting provided on the back surface of the carriage 15, and is arranged symmetrically on the left and right, and by taking two positions (the position shown by the solid line and the position shown by the two-dot chain line in Fig. 3) at the front and rear. The butt passage of knitting needles 2 is changed so that a pattern can be knitted.

The passage changing cam 34 assumes a forward position when the operating pin 30a of the left-right moving plate 30 contacts the concave portion of the operating cam 28, and the operating pin 30a of the left-right moving plate 30 contacts the convex portion of the operating cam 28.

In addition, it is also possible to provide a needle selection instruction mechanism as an attached mechanism on the carriage, and in that case, a counting mechanism and a forming instruction mechanism will be provided on the main body.

The operation of the above configuration will be explained below.

First, the needle selection instruction card 4 is wound around the drum 5 of the needle selection instruction mechanism 3 in preparation for obtaining a predetermined needle selection mode, and then the carriage 15 is slid to the right from the state shown by the solid line in FIG.
(turn the sliding direction of the carriage from left to right) and
The rotating member 16 engages with the small square hole 12b of the attached mechanism operating device from the state shown by the solid line in FIG.
the attached mechanism actuator to the first position.
The figure is moved from the solid line to the two-dot chain line.

Therefore, the actuating member 8 is rotated via the protrusion 8a of the actuating member 8 to the position shown by the two-dot chain line in FIG. , the needle selection instruction card 4 is sent, the signal is converted, and the actuating rod 6 is then moved back to the position shown by the solid line by returning the attached mechanism actuating device from the position shown by the two-dot chain line to the position shown by the solid line. The needles are sorted into two positions, upper and lower, and only the operating rod 6 in the lower position is moved by the movement of the moving member 7, so that the needle selection plate 9 is selectively arranged according to a predetermined needle selection mode.

Further, in the initial stage of the rotation of the rotary member 16, that is, while the rotary member 16 moves from the position shown by the solid line 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. 2, and moves the front-rear moving plate 22 forward via the spring 23.

Therefore, the pawl plate 26 engages with the pawls 29a of the model wheel 29 formed at the lower part of the operating cam 28, and rotates the operating cam 28 to one of the pawls 29a.

Therefore, due to the cam shape of the operating cam 28, in the state shown by the solid line in FIG. When the operating pin 30a comes into contact with the convex portion by rotating, the left-right moving plate 30 is positioned to the left,
The left and right cam operation plates 32 and 33 are moved to the position shown by the two-dot chain line in FIG. 3, and the path changing cam 34 is moved to take the rear position as shown by the two-dot chain line in FIG.

Therefore, the path changing cam 34 can be moved to the front position or the rear position according to the shape of the cam portion 28a of the operation cam 28.

After that, when the carriage 15 is moved, the knitting needles 2 are selected by a needle selection cam (not shown) provided on the carriage 15, and introduced into a predetermined butt passage to knit a pattern. .

Furthermore, when folding back the carriage 15, the attached mechanism actuating device 12
is operated to operate the needle selection instruction mechanism 3, and the rotating member 16 operates the cam operating mechanism 20 to sequentially knit a pattern.

Since the present invention is configured as described above, when the carriage sliding on the needle bed is turned back at an arbitrary position, the mechanism attached on the main body and the mechanism attached on the carriage can be automatically operated. Since the needle selection instructing mechanism and forming instructing mechanism, which are suitable to be provided, and the cam operating mechanism, which is suitable to be provided on the carriage, can be operated when the carriage is turned back at any position, it is necessary to operate the needle selection instructing mechanism and forming instructing mechanism in the pre-knitting stage. These mechanisms, which must be operated beforehand, can be operated reliably, and the pattern knitting of a hand knitting machine can be automated, which is extremely convenient.
