Abstract
Stitching data for embroidery patterns and identification data are stored in ROM of the embroidery ROM card. Stitching data for stitching patterns except embroidery patterns, such as figure patterns or point marks, are stored in ROM of another ROM card. If the card key is operated, it is determined whether the embroidery device is installed on the sewing machine or not, whether a ROM card is installed in the sewing machine or not, and whether the installed ROM card is a ROM card for embroidery or not. If at least either one of the embroidery device or a ROM card is not installed on the sewing machine, or the installed ROM card is not a ROM card for embroidery, warning is given to an operator.
