ABSTRACT:
A sewing machine includes a detection device that detects whether a feed distance by which the piece of work cloth is shifted by a feed dog in the back-and-forth or right-and-left direction has reached a predetermined distance, a counting device that counts a number of forward feed stitches and a number of backward feed stitches which are sewn when the piece of work cloth is shifted backward and forward, respectively, by the predetermined feed distance detected by the detection device or a number of leftward feed stitches and a number of rightward feed stitches which are sewn when the piece of work cloth is shifted leftward and rightward, respectively, by the predetermined feed distance, and a correction value setting device that sets a correction value to correct the feed distance based on a result of the counting of the number of stitches by the counting device.
