ABSTRACT:
A data preparing apparatus is provided for an embroidery sewing machine. The data preparing apparatus comprises a first memory means for storing outline data of an embroidery pattern to embroider. First, a designating means designates a stitch-forming direction so as to embroider within the outline represented by the outline data. Based on the outline data and the stitch-forming direction, a first computing means divides the outline of the embroidery pattern into multiple closed areas by a segment extending in the stitch-forming direction and computes outline data of the divided closed areas. Subsequently, based on the closed-area outline data computed by the first computing means and the stitch-forming direction, a second computing means computes needle location data or block data that is related to needle location. The needle location data or the block data is stored in a second memory means. Each of the closed areas is thus embroidered in the stitch-forming direction. By providing the closed-area outline data, the needle location data or the block data can automatically be prepared. This automatic data preparing apparatus saves the manual designation of the closed areas by an operator, and reduces time required for preparing the data. Even an unexperienced operator easily prepares the data.
