PROBLEM TO BE SOLVED: To provide a sewing machine that can perform circle sewing using a circle sewing device, and can suppress the deviation between a pattern at starting the sewing and a pattern at ending the sewing, even though a subject to be sewn is shrunk in the actual sewing.SOLUTION: A newest image data output from an image sensor is obtained (S41) and a marking position recognized in the image is specified (S43). Based on the specified marking position and a marking position as specified in the previous time, an actually moved distance in a subject to be sewn is specified (S44). When there is an error between a scheduled transported distance indicated by a transported distance data and the actually moved distance (S45:YES), one seam is formed after the error is stored (S46). When one pattern is sewn (S48:YES), a transportation data corresponding to a next seam of the pattern is corrected based on the errors accumulated during the sewing of the patterns (S50). The next seam of the pattern is formed based on the corrected transportation data (S47). |
