ABSTRACT:
A sewing machine is provided with an automatic anti-loosening-stitcher mode selector switch for activating and deactivating the anti-loosening-stitcher mode in which anti-loosening-stitches are formed after the completion of a stitch pattern, and an automatic thread-cutter mode selector switch for activating and deactivating the thread-cutter mode in which threads are cut after the completion of a stitch pattern. When only the automatic thread-cutter mode selector switch is operated to set the thread-cutter activated mode, a CPU sets automatically both the anti-loosening-stitcher activated mode and the thread-cutter activated mode to form anti-loosening-stitches after the completion of a stitch pattern before cutting the threads so that stitches forming the end portion of the stitch pattern are prevented from loosening.
