先端の把持部５a,５a間でボタン９を把持する。The push button 10 is composed of a long shaft member, and is housed in a hole 3f penetrating from the lower surface recess 3e of the swinging portion 3b of the chuck holder 3 to the side opposite to the protruding side of the chuck 5 so as to be movable in the axial direction. . The tip portion 10a of the push button 10, that is, the chuck side end portion is formed in a wide horizontal trapezoidal shape, and has inclined surfaces 10c, 10c on both side surfaces thereof. A contact portion 5c at the rear end of each chuck 5 slidably contacts each inclined surface 10c. The end face of the tip portion 10a has a recessed portion 1 recessed in the axial direction.
0b, the compression spring 12 is inserted into the recess 10b, and the other end of the compression spring 12 is compressed to the bottom of the recess. Therefore, the compression spring 12 is provided on both chucks 5, 5 with both locking projections 5.
b, 5b and the push button 10 are in a stretched state, and the rear end of the push button 10 is projected from the chuck holder 3 by the urging force of the compression spring 12, and the contact portion 5c of each chuck 5 is pushed by the push button 10. The chucks 5a, 5a of the pair of chucks 5, 5 are rotated and biased in a direction in which the grips 5a, 5a of the pair of chucks 5, 5 come into contact with the inclined surfaces 10c of the chucks 5, and the button between the grips 5a, 5a at the tip of the chuck 5 Hold 9

回動付勢されることになる。Now, let us consider a condition under which the chuck 5 is constantly urged by the urging force of the compression spring 12 in a direction in which the tip end thereof is closed. As shown in FIG. 7, the biasing force of the compression spring 12 acting on the locking projection 5b of the chuck 5 is P 1, and the perpendicular line drawn from the axis O of the pivot pin 11 to the line of action of this biasing force P 1 If the length is a, the moment M acting on the locking protrusion 5b
1 is M 1 = P 1 × a. On the other hand, if the biasing force of the compression spring 12 acting on the contact portion 5c of the chuck 5 is P 2, and the length of the perpendicular line drawn from the axis O of the pivot pin 11 to the line of action of this biasing force P 2 is b, The moment M 2 acting on the contact portion 5c is M 2 = P 2 × b. And the moment M
If the absolute value of 2 is larger than the absolute value of the moment M 1 , that is, if | M 2 |> | M 1 |
Is urged to rotate in the direction in which the tip grip portion 5a is closed. Here, if the inclination angle of the inclined surface 10c of the push button 10 with respect to the push button axial direction is α, then P 2 = P 3
Since × sinα and | P 1 | = | P 3 |, the above equation is | P 2 × b |> | P 1 × a | ∴ | P 1 × b × sinα |> | P 1 × a | ∴sinα> (a / b). Therefore, if the inclination angle α of the push button 10 is designed so that sin α> (a / b), each chuck 5 is rotationally biased by the compression spring 12 in the direction in which the tip grip portion 5a of the chuck 5 is closed. It will be.

Then, the needle bar 17 and the needle 14 are moved up and down manually or by driving an electric motor or the like to sew the button 9 to the cloth.
When the button 9 is completely attached to the cloth, the lever 15 is positioned above and the presser 6 is raised, and the swinging portion 3b of the chuck holder 3 is raised by the biasing force of the spring 13. Then, the push button 10 is pushed to open the pair of chucks 5, 5 to release the button 9. In the case of the two-hole button 9, the button can be attached by the above operation, but in the case of the four-hole button 9, the two holes 9a, 9a on the front side among the holes 9a, ... After threading the thread on the cloth and sewing the button 9 to the cloth as described above, the chuck mechanism 3 is rocked by the rocking mechanism 4 so that the two holes 9a, 9a on the other side are positioned at the vertical movement position of the needle 14. Then, a thread is passed through each hole 9a and the button 9 is sewn to the cloth.
