Abstract
Abstract Multiple sewing data which are required for a sewing operation based on a desired pattern and are prepared by a programming device are stored in a card equipped with an integrated circuit capable of reading and writing such data. A stitch forming device and a work fabric feeding device are actuated on the basis of the data, thereby forming stitches on a work fabric.
