Abstract: PURPOSE: To provide an effective embroidery data preparing device for sewing machine by enlarging and shrinking only that stitch data part of sewing data which is judged by a data judging part on the basis of the enlarging/reducing ratio stored as the reference. CONSTITUTION: The enlarging/reducing ratio, for example the reduction, is first inputted and a scale key is pushed, followed by pushing of an enlarge/ reduce key and a key 2 to specify enlargement or reduction, and then the numeral corresponding to the specified needle number is inputted from a numeral key in the menu part 11 of a stitch data part. Then, the start key is pushed. Because the number of specify enlargement or reduction is '2', the reducing process is started when the specified needle position is used as reference. Among the sewing data before reduction stored in a main memory RAM the stitch data is judged based upon whether the contents of a control command indicate an idle feed or a sew command by a data judging means from the first one in the leading place of the address, and the X- and Y-feed quantities are calculated by a CPU according to the reduction ratio by reference to the stitch data of the specified needle position, and thus reduction is conducted.
