(57) An automatic winder (yarn winding machine) includes a transportation tray 39, a chase portion detecting sensor 74, a yarn quality measuring device, and a yarn quality inspecting section. A yarn supplying bobbin 15 is set in the transportation tray 39. The chase portion detecting sensor 74 detects an unwinding position of the yarn supplying bobbin 15 set in the transportation tray 39. The yarn quality measuring device measures quality of a yarn unwound from the yarn supplying bobbin 15. The yarn quality inspecting section manages the quality of the yarn in accordance with the unwinding position detected by the chase portion detecting sensor 74 and the quality of the yarn measured by the yarn quality measuring device.
