換えることも可能である。The solenoid stopper 31 is rotatably supported by a solenoid holder 39. When the solenoid 35 is excited at the start of the thread cutting operation, the control cam 27 is activated.
Although it is rotated to a position where it can be prevented from rotating, it is held by the torsion spring 37 at the position shown in FIG. 1 where it does not contact the convex portion 27A of the control cam 27 in the sewing state. The pressing spring 25 constitutes a spring means for elastically disposing the thread cutting blade drive cam 21 at a fixed position in the axial direction, and includes a solenoid stopper 31 and a solenoid 35.

コロ19とが軸線方向で係合する状態となる。The layout of the members shown in FIG. 1 is in the sewing operation or in the stopped state. First, when the thread cutting operation is instructed, the solenoid 35 is excited to rotate the solenoid stopper 31 to a position where it can come into contact with the outer peripheral projection 27A of the control cam 27. The control cam 27, which started to rotate together with the drive shaft 3 and the thread cutting blade drive cam 21 at the same time as the excitation of the solenoid 35, has the convex portion 27A of the control cam 27.
When it comes into contact with 1, it stops at the position shown in FIG.
From this point of time, the drive shaft 3 and the thread cutting blade drive cam 21 continue to rotate, and the inclined surface of the convex actuating cam 27B of the control cam 27 which is stopped is changed to the concave portion 21C of the thread cutting blade drive cam 21.
While climbing as shown in FIG. 4, the thread cutting blade drive cam 21
Starts to move to the left in the axial direction against the pressing force of the pressing spring 25, and finally, as shown in FIG. 6, it is provided on the drive cam 21A of the thread cutting blade drive cam 21 and the swing arm 15. The roller 19 and the roller 19 are engaged with each other in the axial direction.

方向位置に復帰する。From this state, the drive shaft 3 and the thread cutting blade drive cam 21 continue to rotate, and as shown in FIGS. 7A and 7B, the swing arm 15 is driven by the drive cam with which the roller 19 abuts. According to the cam lift of 21A, the thread cutting movable blade 1 is rotated and reciprocated through the angular roller 13, the transmission arm 7, the connecting rod 9, the holder 5, and the like. During the rotary reciprocating motion, the thread cutting movable blade 1 cuts the upper thread and the lower thread by the cooperation of the thread cutting fixed blade 45 to end the thread cutting operation. After this thread cutting, the thread cutting movable blade 1 is linked with the holder 5 9
The force of the pulling spring 43 urged to return to the rotational position in the sewing state.

される。It should be noted that, while the thread cutting movable blade 1 makes a rotational reciprocating motion by the cam lift of the drive cam 21A, the thread cutting blade drive cam 21 is pushed by the load resistance given by the roller 19 to the drive cam 21A. The pressing force of 25 is invalidated, and a fixed state occurs in the axial direction. If the thread cutting blade drive cam 21 continues to rotate in this state, the recess 21
The convex actuating cam 27B of the control cam 27 is pushed to C by the push spring 33.
As shown in FIG. 8, it falls due to the axial pressing force of. At this time, the control cam 27 moves to the left in the axial direction and contacts the thread cutting blade drive cam 21. At this point, the contact state between the solenoid stopper 31 and the convex portion 27A of the control cam 27 is released.

Swinging arm 15 that reciprocates by the cam lift of
The stopper 41 works in conjunction with the projection 27C of the control cam 27.
Since it rotates to a position where it comes into contact with, the rotation is stopped again. The control cam 27 remains rotated until the end of thread cutting. Immediately after the roller 19 provided on the rocking arm 15 receives the action of the maximum cam lift of the drive cam 21A (immediately after the thread cutting movable blade 1 and the thread cutting fixed blade 45 cut the upper thread and the lower thread), The fixed state of the thread cutting blade drive cam 21 in the axial direction is released when the load resistance of the roller 19 to the drive cam 21A disappears.

Due to the axial pressing force of 5, the thread cutting blade drive cam 21 and the control cam 27 resist the pressing force of the pressing spring 33, and
It is pushed back to the state position as shown in. Further, the solenoid 35 finishes its excitation until the pushing spring 25 moves the thread cutting blade drive cam 21 and the control cam 27 to the sewing state position from the start of the excitation against the pushing force. At this point, the thread cutting operation by all the members ends.
