ABSTRACT:
A system is disclosed in which an information carrying member with multiple pieces of pattern information recorded thereon to control a stitch forming instrumentality is rotated intermittently by a step motor in forward and reverse directions according to a sequence predetermined for each stitch pattern. Each group of pattern information corresponding to each of the stitch patterns is recorded individually within a plurality of defined regions on the information carrying member, whose intermittent rotation effected at a rate of a small angle per step enables a scanning member to make a reciprocation relatively to the information carrying member within a preselected region, thereby sequentially picking up the pattern information related to placement of the stitches required for generating a desired stitch pattern.
