様発生機構。[Claims for Utility Model Registration] (1) A drive shaft rotatably supported within the sewing machine frame, and a cam follower whose one end is removably supported on the outer periphery of a pattern cam that is linked to the rotation of the drive shaft. and a needle bar support that is caused to swing in a width direction via a connecting rod when one end of the cam follower is engaged with the pattern cam, the needle bar support body is configured to rotate at a reduced speed in conjunction with the rotation of the drive shaft. a first pattern cam that is attached to the first pattern cam; a second pattern cam that is attached coaxially with the first pattern cam; and a first cam that is made to engage and disengage from the first pattern cam by operating a pattern selection section; a second pattern cam that is engaged with and disengaged from the follower and the second pattern cam;
1. A pattern generating mechanism for a zigzag sewing machine, comprising: a cam follower; and an engaging portion for engaging the first cam follower and the second cam follower. (2) The driving means for the second pattern cam is the driving means for the second pattern cam.
an elongator operating claw that is driven by an elongator operating cam provided on the pattern cam; an engaging/disengaging means that intermittently drives the second pattern cam by rotation of the elongator operating claw; and a rotation angle of the elongator operating claw. The pattern generating mechanism for a zigzag sewing machine according to claim 1, further comprising an adjusting means for adjusting the amount of rotation of the second pattern cam.
