ABSTRACT:
Stitch patterns are converted into coordinate data by an optical scanner employing a charge coupled device (CCD) which provides multiple PN diodes internally (providing X-direction coordinates), and a pulse motor driven by a predetermined pulse (providing Y-direction coordinates). The coordinate data are stored in random access memory (RAM) via a central processing unit (CPU), thereby eliminating the conventional manual work of inputting data for each stitch point.
