ABSTRACT:
A plurality of different stitch patterns are stored in a first static memory. A second static memory memorizes a combination of these different patterns in a predetermined sequence. A third static memory stores basic needle position signals each specific to the patterns stored in the first memory. Calculating means utilize signals derived from the second memory and the third memory to determine values for adjusting the swinging amplitude of the sewing needle with a common variation rate and for setting a common basic needle position.
