    摘要: A method for controlling a computerized sewing machine which enables designs or patterns of modified length with respect to the standard value of each original design or pattern available to be sewn while retaining the density of stitches and the general shape of the original design. Algorithms are utilized indicating, for each block of stitches included in the original design or pattern, the number of times that this block is to be sewn to obtain the design of modified length. The microprocessor sewing machine using the method of the invention includes means requiring the microprocessor to read ongoing instructions repeatedly for at least certain blocks among the block of stitches for the basic design or pattern.

    摘要: A method and apparatus, for use with a sewing machine, for modifying stitching data representing a pattern that the sewing machine is to sew. The stitching data includes non-stitching feed data, in accordance with which the sewing machine feeds a needle without sewing from an origin position to a sewing start position, and seam data including information defining feeding directions and feed amounts per stitch, in accordance with which the sewing machine sews the pattern. A data identifying device identifies the seam data of the stitching data. A seam data changing device converts, in accordance with an enlargement/reduction ratio stored in a storage device of the sewing machine, the seam data identified by the data identifying device into new seam data representing a new pattern which is an enlarged version of the original pattern enlarged or reduced relative to the sewing start position, without modifying the non-stitching feed data. A non-stitching feed data creating device creates new non-stitching feed data. Also, a center determining or calculating device determines or calculates the center of the new pattern, so that the seam data changing device converts the seam data with reference to this center.
