Based on the position data stored in the memory and the stitch number data set by the manual input device, a microprocessor connected thereto calculates the position data of the actual stitch forming positions; and a drive mechanism relatively moves the needle and the workpiece according to the position data calculated. Many cell stitch patterns thus formed on the workpiece turns out to be a desired unit stitch pattern such as a letter, symbol and other patterns.
