摘要： A button-hole earn is mounted on a pattern selection cam shaft for mounting a pattern selection cam, the pattern selection cam shaft provided independently of a pattern cam shaft provided with a needle swing cam group. The rotation of a sewing machine main shaft causes rotation of a drive gear which in turn rotates a first follower gear in engagement with the drive gear and a second follower gear engaged with the first follower gear. Thus, the rotation of the first follower gear causes rotation of the needle swing cam group whereas the rotation of the second follower gear causes rotation of the button-hole cam. Thus, a pattern selected among a plurality of patterns by a pattern selection dial is generated to form button-hole stitches selected by the pattern selection dial.
摘要翻译：在图案选择凸轮轴上安装钮扣孔，用于安装图形选择凸轮，图案选择凸轮轴独立于设置有针摆动凸轮组的图案凸轮轴设置。缝纫机主轴的旋转引起驱动齿轮的旋转，驱动齿轮又使与驱动齿轮啮合的第一从动齿轮和与第一从动齿轮啮合的第二从动齿轮旋转。因此，第一从动齿轮的旋转引起针摆动凸轮组的旋转，而第二从动齿轮的旋转引起按钮孔凸轮的旋转。因此，生成通过图案选择盘从多个图案中选择的图案，以形成由图案选择转盘选择的按钮孔针迹。
