  • Patent number: 5677843
    Abstract: All embroidery data in a flash memory card are copied to a RAM, and file numbers of the embroidery data copied to the RAM are displayed on a LCD. When the user selects the embroidery data to be erased, the data are erased from the RAM and the LCD. When the selection of the data to be erased is over and an end key is pressed, the flash memory card is initialized, and thereafter the remaining embroidery data left on the RAM are copied to the flash memory card. Accordingly, the operation of rewriting the data in the flash memory card is completed at one time, with the result that the rewriting time required for the erasing of plural embroidery data can be greatly reduced.

  • Patent number: 5576968
    Abstract: An embroidery data creating system capable of creating embroidery data that enables an operator having no knowledge of stitch characteristics to form an embroidered pattern having a beautiful appearance. The operator scans an original picture with an image scanner to obtain image data and coordinates of points defining a closed embroidering region are extracted from the image data. An end point, e.g., the lowermost point among the points specified by the extracted coordinates, is specified, the rightmost point and the leftmost point among the points specified by the extracted coordinates are determined, a stitching direction is determined on the basis of the greatest distance of the distance between the rightmost point and a boundary line passing through the end point and perpendicular to the embroidering direction and the distance between the leftmost point and the boundary line, and embroidery data is created on the basis of the stitching direction and the coordinates of the boundary points.

  • Patent number: 5563795
    Abstract: An original picture of a pattern is scanned with an image scanner to obtain bitmap image data. A border line defining the original picture is extracted. A closed region enclosed by the border line is subjected to a linearizing process. Shape-defining line data is produced for the closed region and stitch data for entirely covering the closed region with zigzag stitches when the closed region can completely be linearized by a number of sequential pixel deleting cycles not greater than a given number. Border line data is produced and stitch data for entirely covering the closed region with satin stitches is automatically produced when the closed region could not be completely linearized by the number of sequential pixel deleting cycles within the given number. Thus, stitch data for satisfactorily embroidering a pattern consisting of a plurality of partial patterns respectively having different widths can be readily and automatically produced from the original picture of the pattern.

  • Patent number: 5558032
    Abstract: In an embroidery data preparing device for preparing embroidery seam data on the basis of an original picture pattern for embroidery, a plurality of desired different sizes are selected for the same pattern to be embroidered and stitch and the sizes are stored in a memory device. An original picture pattern is read out by an image scanner to obtain the original picture data and then outline data are extracted from the original picture data. The outline data are divided into a plurality of blocks, for closed areas, to obtain intermediate embroidery data. The intermediate embroidery data are enlarged or reduced at a magnifying power corresponding to each desired pattern size and embroidery seam data are obtained for each desired pattern size on the basis of the enlarged or reduced intermediate embroidery data to thereby collectively prepare the embroidery seam data for the plurality of different pattern sizes.
