Abstract
A sewing machine includes a needle plate with a cutout part, and a guide plate connected to a bottom side of the needle plate and extending substantially across the cutout part. The guide plate includes a pair of slide rails, an opening substantially corresponding in position to a bobbin case, and a curved thread guide slot having one end communicated with the opening and another end extending to one of the slide rails. A slide cover covers the cutout part and is slidable along the slide rails. A cutter is disposed at the lateral edge proximate to one of the slide rails. A lower thread guide extends along one of the slide rails from another end of the thread guide slot toward the cutter for guiding a lower thread from the bobbin case to extend to the cutter.
