Reference numerals 19 and 19' designate limiting members that limit the range of movement of the operating member 15, one end of which is a bending elastic part 19a, 19'a so that it can be located within the movement range of the pin 15b, and the intermediate part of which is used for the carriage 14. Insertion holes 19b and 19'b are bored through which the pin 14b fixed to the pin 14b is inserted, so that this limiting member can move only in the left and right direction, and a U-shaped notch 19c is formed at the other end.
, 19'c.

Reference numeral 20 denotes a switching lever which is pivotally connected to the carriage 14 about a shaft 21.

The pin 20a fixed to the switching lever 20 and the carriage 1
A spring 23 is hung between the switch lever 20 and a pin 22 fixed to the switch lever 20, so that the switch lever 20 receives elastic force in either direction when the switch lever 20 swings.

20b and 20'b are a pair of pins fixed to the switching lever 20, which project downward from the insertion hole 14c formed in the carriage 14, and the pin 20b is inserted into and engaged with the U-shaped notch 19c of the restriction member 19. However, the pin 20'b is inserted into and engaged with the U-shaped notch 19'c of the limiting member 19.

Therefore, when the switching lever 20 is in the position shown by the solid line in FIG.
5b, the range of movement of the operating member 15 is limited to a position where it can engage with the operating member 4, that is, an operating position.

Further, the switching lever 20 is moved to the position shown by the two-dot chain line in FIG. 3, and the limiting member 19 is moved to the right position, the limiting member 19' is moved to the left position (as shown by the two-dot chain line in FIG. 3), and the operating member is moved to the position shown by the two-dot chain line in FIG. 15 is rotated and retracted by the elasticity of the panel 18 to a non-operating position where it does not engage with the operating member 4 and does not operate the attached mechanism.

Note that when the limiting members 19 and 19' are in the positions shown by the solid lines and broken lines in FIG. It is configured.

This embodiment is constructed as described above, and its operation will be explained below.

First, when the switching lever 20 is placed at the position shown by the solid line in FIG. 3, the limiting members 19, 19 are placed at the positions shown by the solid line and broken line in FIG. 3 via the pins 20b, 20'b.

Assuming that the operating member 15 is now shown by the solid line in FIGS. 1 and 3, if the carriage 14 is moved in the direction of arrow B in FIG. As the carriage 14 advances, the actuating member 4
is gradually moved in the same direction as the advancing direction of the carriage 14 from the forward position shown by the solid line against the spring 11, and the actuating member 4 is supported and pivoted by the supporting member 8, so that
Due to the action of the shaft 10 and pin 9 of the support member 8, the support member 8 moves backward to the right while remaining parallel to the longitudinal direction of the needle bed 1.

At this time, the operating member 15 rotates about the shaft 16 in the counterclockwise direction in FIGS. reaches the rear position indicated by the two-dot chain line.

If the carriage 14 is further advanced, the left protrusion T of the operating member 15 will be disengaged from the square hole 5 of the operating member 4, and the right protrusion will mesh only with the square hole 5 adjacent to the right, and the operating member 15 will be moved by the spring 18.
Due to the elasticity of the spring 11 and the return elasticity of the spring 11 which attempts to return the actuating member 4 to the forward position, the actuating member 4 is rotated counterclockwise in FIGS. The limiting member 19 reaches the position indicated by the dashed line in FIG.
The pin 15b comes into contact with the bending elastic portion 19'a of '.

In this state, the projection T of the operating member 15 is
When the carriage 14 is moved in the direction opposite to the direction of the arrow B in FIG. 1, the right protrusion T immediately comes into contact with the left end of the square hole 5, and the carriage moves as the carriage moves. The member 4 is moved to the rear left position indicated by the dashed line in FIG.

That is, the actuating member 4 moves at the turn of the movement of the carriage 14.

By moving the operating member 4 back and forth, the bending plate 6 and the operating shaft 7 are
is moved back and forth to operate a needle selection device, which is an example of an attached mechanism.

That is, the needle selection card 12 is transferred, and a desired one of the plurality of needle selection plates 13 arranged side by side is moved to a needle selection preparation position in response to a signal from the needle selection card 12.

Next, when moving the carriage 14 without operating the operating member 4 to perform knitting or the like, the switching lever 20 is rotated about the shaft 21 from the position shown by the solid line in FIG. 3 to the position shown by the two-dot chain line. Then, the spring 23 holds the position, and the pin 20
b moves the limiting member 19 to the right through the U-shaped notch 19c, and the pin 20b moves the limiting member 19' to the left via the U-shaped notch 19'c. Move from the position shown by the broken line to the position shown by the two-dot chain line.

Accordingly, the operating member 15 is rotated by the elasticity of the spring 18 to the position shown by the two-dot chain line in FIG. 3, and the tip 15a thereof does not engage with the operating member 4 and becomes a non-operating position in which the attached mechanism is not operated.

Therefore, even if the carriage 14 is moved, the attached mechanism will not be activated.

As described in detail above, the present invention is provided with a limiting member that holds the operating member to actuate the attached mechanism by limiting the movement range of the operating member, and the operating member is always in elastic contact with the limiting member and A simple mechanism in which the movement range of the operating member can be changed by moving the limiting member allows the operating member to be retracted to an inactive position where the attached mechanism cannot be operated, thereby activating unnecessary devices. When only the carriage is moved, it can be moved easily, and the mechanism is easy to manufacture and can be manufactured at low cost.
