ABSTRACT:
In an automatic pattern generation type sewing machine, a function generating device generates stitch positions using a signal synchronous with the rotation of the armshaft of the sewing machine, a digital signal generating device provides digital signals corresponding to the stitch positions, and a servo driving device, using the digital signals, moves the cloth or the needle, to thereby form a variety of geometrical stitch patterns automatically.
