Sewing machine and computer-readable medium storing sewing machine control program

A sewing machine that is included in a sewing system that, using a plurality of the sewing machines, performs sewing of a single embroidery pattern on a work cloth that is held by an embroidery frame, the sewing machine comprising:

• a transfer device that includes a carriage to which the embroidery frame can be attached and that is adapted to transfer the carriage;
• a sewing device that moves a needle bar, to a bottom end of which a needle is attached, up and down;
• an image capture device that is adapted to capture at least one image of at least one marker that is positioned in a marker area, the marker area being on at least one of the embroidery frame that is attached to the carriage and the work cloth that is held by the embroidery frame;
• a condition acquisition device that acquires a pattern condition that is a condition for specifying at least one partial pattern among a plurality of partial patterns that form the embroidery pattern as a whole, the at least one partial pattern being allocated to the sewing machine;
• a data acquisition device that acquires pattern data that are data for sewing the at least one partial pattern that is specified by the pattern condition and that is allocated to the sewing machine;
• a computation device that computes, as a positioning condition, at least one of a reference position and a reference angle of the at least one marker in relation to the carriage, based on image data that are generated by the image capture device;
• a correction device that, based on the positioning condition that is computed by the computation device, sets a position and an angle of the partial pattern in relation to the carriage and corrects the pattern data that are acquired by the data acquisition device;
• and
• a sewing control device that performs sewing of the partial pattern by controlling the transfer device and the sewing device in accordance with the pattern data that are corrected by the correction device.

A non-transitory computer-readable medium storing a control program executable on a sewing machine that is included in a sewing system that, using a plurality of the sewing machines, performs sewing of a single embroidery pattern on a work cloth that is held by an embroidery frame, the program comprising instructions that cause a controller of the sewing machine to perform the steps of:

• acquiring a pattern condition and a setting condition, the pattern condition being a condition for specifying at least one partial pattern among a plurality of partial patterns that form the embroidery pattern as a whole, the at least one partial pattern being allocated to the sewing machine, and the setting condition being a condition for specifying a position and an angle of the embroidery pattern in relation to at least one marker;
• acquiring pattern data that are data for sewing the at least one partial pattern that is specified by the pattern condition and that is allocated to the sewing machine;
• computing, as a positioning condition, based on image data that are generated by an image capture device that captures at least one image of at least one marker that is positioned in a marker area, at least one of a reference position and a reference angle of the at least one marker, in relation to a carriage to which the embroidery frame is removably attached, the marker area being on at least one of the embroidery frame that is attached to the carriage and the work cloth that is held by the embroidery frame;
• setting a position and an angle of the partial pattern in relation to the carriage, based on the positioning condition and the setting condition, and correcting the pattern data;
• and
• performing the sewing of the partial pattern by controlling a transfer device and a sewing device in accordance with the corrected pattern data, the transfer device including the carriage and being adapted to transfer the carriage, and the sewing device that being adapted to move a needle bar, to a bottom end of which a needle is attached, up and down.
