ABSTRACT:
A sewing machine includes a head on which a needle bar for fixing a needle is mounted, a thread cutting blade mounted in the head so as to be capable of cutting an end of a thread which is threaded so as to be passed through an eye of the needle, and a holder mounted in the head so as to be capable of holding the thread end after the thread end has been cut by the thread cutting blade. The thread cutting blade is positioned so that a first amount of thread from the eye of the needle mounted in the head to the thread end held by the holder equals a second amount of thread by which the thread end is drawn to an underside of a cloth in a stitch formed immediately after start of a sewing operation.
