Abstract:
1. A sewing machine that is capable of sewing an embroidery pattern on a work cloth that an embroidery frame is configured to hold, the sewing machine comprising: a transfer device that transfers the embroidery frame detachably attached thereto; a storage device that stores embroidery data that is data for sewing the embroidery pattern and that includes at least coordinate data that indicates a plurality of needle drop positions in relation to a reference position, each of the plurality of needle drop positions being a point where a needle pierces the work cloth; a first selection device that selects first embroidery data from the embroidery data that is stored in the storage device, the first embroidery data being embroidery data for a first pattern that is at least a portion of the embroidery pattern; a first control device that performs sewing of the first pattern on the work cloth by controlling the transfer device based on the first embroidery data that was selected by the first selection device; an image capture device that captures an image of the work cloth onto which a marker that can be affixed onto the work cloth is affixed; a first detection device that detects at least one of a first marker position and a first marker angle based on information for a first image, the first marker position being a position of the marker that has been affixed onto the work cloth in relation to the reference position, the first marker angle being an angle of the marker in relation to a reference direction, and the first image being an image captured by the image capture device of the work cloth on which the first pattern has been sewn by the first control device; a second detection device that detects at least one of a second marker position and a second marker angle based on information for a second image, the second marker position being a position of the marker that has been affixed onto the work cloth in relation to the reference position, the second marker angle being an angle of the marker in relation to the reference direction, the second image being an image captured by the image capture device of the work cloth one of after a position of the work cloth on which the first pattern has been sewn has been changed in relation to the embroidery frame and after a position of the embroidery frame that holds the work cloth on which the first pattern has been sewn has been changed in relation to the transfer device; a difference computation device that computes at least one of a position difference and an angle difference, the position difference being a difference between the first marker position that was detected by the first detection device and the second marker position that was detected by the second detection device, and the angle difference being a difference between the first marker angle that was detected by the first detection device and the second marker angle that was detected by the second detection device; a second selection device that selects second embroidery data from the embroidery data that is stored in the storage device, the second embroidery data being embroidery data for a second pattern that is at least a portion of the embroidery pattern and that is adjacent to the first pattern; a conversion device that converts coordinate data in the second embroidery data based on the at least one of the position difference and the angle difference that was computed by the difference computation device; and a second control device that performs sewing of the second pattern on the work cloth on which the first pattern has been sewn by controlling the transfer device based on the second embroidery data that includes the coordinate data that was converted by the conversion device.
