In an embroidery data display apparatus, four pattern names &ldquo;A01&rdquo;, &ldquo;A05&rdquo;, &ldquo;A10&rdquo; and &ldquo;A17&rdquo;, for example, from which an embroidery pattern actually used for embroidering may be selected, are designated from a plurality of pattern names displayed on a CRT display, and pattern display data for the designated pattern names are generated in a time-sharing manner with background processing that is effected for minute time intervals &agr; parallel with main processing. The pattern display data thus generated are successively displayed on a display upon completion of each set of data. When it is confirmed that the displayed pattern is the embroidery pattern to be actually used for embroidering, a stop key provided in a keyboard is operated to generate a stop command, which is accepted by the main processing even during generation of pattern display data, so that the pattern display data generating operations can be immediately terminated.

Embroidery pattern display apparatus

An embroidery data process using a computer to extract stitch points from embroidery data and display the contours of an embroidery pattern to the user based on those stitch points. After the stitch points are extracted from the sewing data, an orthogonal coordinate system is defined by setting the first stitch point as the origin and the line formed from the first to the second stitch points as the X-axis. Then, using the first stitch point as the origin, the X components of the second and third stitch points are compared. If the X component of the second point is larger than that of the third, the second stitch point is determined to be a contour point. By continuing this process, all the contour points can be accurately extracted from the sewing data and displayed for the user. Also, to collect only the contour points, half stitch needle locations are detected. For example, for an array (Qi) of odd locations, the stitch point Qi+1 is determined to be the half stitch when a sign of the Y component of Qi+1 on an orthogonal coordinate system is in coincidence with a sign of the Y component of the stitch point in an array of even locations. The coordinate system is defined by setting Qi as the origin and the line formed from Qi to Qi+2 as the X-axis.

Embroidery data processing for extracting contour of an embroidery

A sewing machine control device that is capable of controlling a plurality of sewing machines, and that includes a display unit having a screen; an operability determination unit that determines operable ones of the plurality of sewing machines; and a window displaying unit that displays, on the screen of the display unit, a window for each operable sewing machine.

Sewing machine control device with display for displaying control

Disclosed is a sewing system including a plurality of sewing machines and a controlling device which is electrically connected with the plurality of sewing machines for transmitting control commands to the plurality of sewing machines. The controlling device includes a memory device which stores identification data for identifying each of the plurality of sewing machines, a data registering device, which is used for registering arbitrarily registered data in relation to the identification data stored in the memory device for identifying each of the plurality of sewing machines, and a displaying device having a display screen. The controlling device displays the arbitrarily registered data on the display screen for identifying each of the plurality of sewing machines, and the control commands are transmitted to sewing machines identified by the arbitrarily registered data displayed by the displaying device.
