向に対する直角方向の位置が調整される。Furthermore, when forming the stitches 3 on the object to be sewn 2, a well-known cloth feeding operation is performed by a cloth feeding device (not shown) in synchronization with the reciprocating movement of the needle 1. This cloth feeding device performs a feeding operation in synchronization with the rotation pulse signal of the sewing machine, and at this time, a motor drive control device (not shown) drives the motor 16 in response to the rotation pulse signal of the sewing machine. and,
As the motor 16 rotates, the cam body 18 attached to the rotating shaft 17 of the motor 16 also rotates, and the cam body 1
The rotation of 8 causes the oscillating body 9 to oscillate. That is, the cam body 18
rotates eccentrically around the rotating shaft 17, and when the contact portion 18a of the cam body 18 is located on the rocking body 9 side, the cam body 1
8 and the rocking body 9 are in a non-contact state, and the end portion 9a of the rocking body 9 swings downward about the support shaft 20 by the urging force of the spring 14. On the other hand, when the detached portion 18b of the cam body 18 is located on the rocking body 9 side, the cam body 18 and the rocking body 9 are in contact, and the rocking body 9 is connected to the spring 14.
The end portion 9a swings upward using the support shaft 20 as a fulcrum against the urging force of. As a result, the contact portion 18a of the cam body 18
When is located on the rocking body 9 side, the rotary wheel 8 and the workpiece 2 are in contact with each other, and the rotary ring 8 is pressed against the workpiece 2 (see FIG. 2). On the other hand, the detachment portion 18 of the cam body 18
When b is located on the rocking body 9 side, the contact state between the rotary wheel 8 and the workpiece 2 is released, and the rotary wheel 8 and the workpiece 2 are separated (see FIG. 3). In this way, the rocking body 9
The swinging is synchronized with the rotation of the sewing machine and also with the cloth feeding operation by the cloth feeding device. Therefore, while the workpiece 2 is moving in the cloth feeding direction, the rotating wheel 8 and the workpiece 2 are separated from each other, and the rotating wheel 8 prevents the workpiece 2 from moving in the cloth feeding direction. You won't be disappointed. Further, while the movement of the workpiece 2 in the cloth feeding direction is in a stopped state, the rotating wheel 8 and the workpiece 2 are in contact with each other, and at this time, the rotation of the cloth section driving wheel 8a causes the workpiece to be sewn. The position of No. 2 in the direction perpendicular to the cloth feeding direction is adjusted.

Therefore, sewing can be performed correctly at the correct position on the object 2 to be sewn. Moreover, unlike the conventional sewing machine, the sewing guide device for the sewing machine does not pull the fabric, which is the object to be sewn 2, during the cloth feeding operation, and does not create resistance during cloth feeding. Therefore, the material to be sewn 2 is properly fed by the cloth feeding operation, the pitch of the stitches 3 is stabilized, wrinkles can be prevented from occurring in the material to be sewn 2, and the sewing finish is improved.
