摘要： A thread winder unit, which is capable of winding thread of spools set on spool bars, is removably attached to a machine body. The sewing machine includes a feed motor for feeding the thread during sewing, an upper thread state detecting sensor disposed between the feed motor and the thread winder unit for detecting tensed thread, and a CPU for controlling thread winding operations based on a signal from the upper thread state detecting sensor. The sewing machine intermittently drives the feed motor in a reverse direction to that in the sewing to feed the thread toward the thread winder unit, every time the upper thread state detecting sensor detects the tensed thread, and the thread winder unit winds the fed thread around the spool. The CPU, recognizing the thread wound by a given amount, stops winding.
