A multi-needle sewing machine includes a plurality of needle bars having lower ends to which needles are attached, respectively, a needle bar selecting unit selectively switching one of the needle bars to a needle location, a stitch number obtaining unit and an allotting unit. An embroidery pattern including a plurality of partial patterns is sewn by the use of needle threads of colors differing per partial pattern, while the needle bars are selectively switched. The stitch number obtaining unit obtains the number of stitches necessary for sewing the partial patterns for every partial pattern. The allotting unit allots the needle threads to the needle bars so that the needle bars are prevented from being one-sided in the number of stitches, based on the obtained number of stitches, in order that one of the needle bars to be used for the sewing of each partial pattern may be determined.

Sewing data of multiple sewing targets stored in RAM of a sewing sequence determining apparatus is acquired. Permutations or combinations of the sewing targets are created as sewing sequence candidates. A number of needle bars N provided at a multi-needle sewing machine is acquired. An optimal thread replacement count is initialized. A thread replacement count is calculated for each of sewing sequence candidates, in the case where sewing operations are carried out by the multi-needle sewing machine equipped with N needle bars on the sewing targets in accordance with the sewing sequence candidates. A sewing sequence candidate of the fewest thread replacement count is determined to be an optimal sewing sequence candidate. The optimal sewing sequence candidate is displayed on a liquid crystal display and announced. Determination of sewing sequences at the time of carrying out sewing operations with respect to multiple sewing targets is easily achieved.

Apparatus for determining sewing sequences, program for determining sewing sequences recorded on computer-readable recording medium, and sewing machine

An embroidery data creation apparatus and program acquires closed region data of a target unit pattern with a sewing order specified by a unit pattern counter and position data of a sewing endpoint of a preceding unit pattern to be sewn immediately prior to this target unit pattern. Based on the closed region data and the position data of the sewing endpoint, it is determined whether a sewing endpoint of the preceding unit pattern is present in a sewing region of the target unit pattern. If it is determined that the sewing endpoint is present in the sewing region of the target unit pattern, thread-cutting operation at this sewing endpoint is set not to be performed. On the other hand, if it is determined that the sewing endpoint is not present in the sewing region of the target unit pattern, thread-cutting operation at this sewing endpoint is set to be performed or withheld.

Embroidery data creation apparatus and embroidery data creation program

A multi-needle type embroidery sewing machine and a computer-readable storage medium including a computer program for the multi-needle type embroidery sewing machine that may enable convenient selection and replacement of thread information. The multi-needle type embroidery sewing machine may include a plurality of needle bars, a needle bar thread information storage device, a needle bar selection device that enables the selection of a suite of needle bars selected from the plurality of needle bars, and a control device for changing needle bar thread information that corresponds to a needle bar in the selected suite of needle bars.

When a user specifies, as an embroidery sewing condition, an embroidery pattern that can be sewn with thread spools set for needle bars, embroidery data on an embroidery pattern and needle bar thread information on a thread set for a needle bar are read and stored in a RAM. Embroidery thread information included in embroidery data is read out in a sequential order, and embroidery thread information and specified thread information are compared with each other. An embroidery pattern having embroidery data of which all of the embroidery thread information is coincident with the specified thread information is extracted as an embroidery pattern that satisfies the embroidery sewing condition. The extracted embroidery pattern is then displayed on a liquid crystal display.

Embroidery data processing apparatus, embroidery data processing program recorded on computer-readable recording medium, and sewing machine

A complex data processing device that processes embroidery data representing an embroidery pattern to be formed on fabric by a sewing machine capable of embroidering and print data representing print pattern to be printed on the fabric by a printer. The complex data processing device includes a data acquiring unit that acquires the embroidery data and the print data, an overlapped region detecting unit that detects an overlapped region at which an embroidery region represented by the embroidery data and a printing region represented by the print data overlap based on the embroidery data and the print data acquired by the data acquiring unit, and a data modifying unit that deletes data corresponding to the overlapped region detected by the overlapped region detecting unit from at least one of the embroidery data and the print data.

There is provided a embroidery data processing device, which includes an extracting system that extracts at least one embroidery region from embroidery data that has a stitch attribute corresponding to at least one predetermined setting, and a print data generating system that generates print data for the at least one embroidery region extracted by the extracting system based on the embroidery data of the at least one embroidery region extracted by the extracting system.

Embroidery data processing device

In an embroidery data processing apparatus, each time an editing action is executed with respect to an embroidery pattern to be edited, the name of the editing action is stored to an edit history memory. When a certain key is operated to effect retrospective and repetitive editing control, the names of the executed editing actions stored in the edit history memory are displayed on a CRT display and, if a mouse is operated so that one of the editing actions, for example, 'ENLARGE', that is three steps before the current state is directly designated by a marker M, and a 'RETURN' key is operated, embroidery data in the state before execution of the designated editing action can be obtained instantly. After new processing, such as addition or deletion of editing action, is effected, editing actions, such as 'LATERAL MIRROR' and '90% CLOCKWISE ROTATE', that follow the designated editing action are automatically re-executed.

Embroidery data processing apparatus

A sewing machine according to the invention has a display for displaying sewing data as an image corresponding to the sewing positions on a material. A material mover is controlled to move the material relative to a head without causing a needle to vertically move, and thereby the stitch position defined by the head is moved to an arbitrary point indicated on the image on the display. As a result, the material can be moved quite quickly compared with a case where the material is moved stitch by stitch. In addition, since the position to which the stitch position is moved can be confirmed on the screen, designation of that point is performed quite easily.

Sewing machine having display means

Contour data representing the contour of an embroidering area to be covered up with stitches formed by an embroidery machine is read from a contour data storage means and the contour of the embroidering area is displayed on a display on the basis of the contour data. A desired stitching direction for at least one point in the embroidering area is specified by the operator. The embroidering area is divided into a plurality of embroidering sections by dividing line segments parallel to the specified desired stitching direction. A reference point is set for each embroidering section. Each embroidering section is divided into blocks so that the respective contours of all the blocks are convex, and then embroidery data is produced.
