Abstract
A sewing machine capable of preventing formation of no first stitch (skipping stitch), which is readily caused immediately after the sewing machine starts to operate, is obtained. This sewing machine comprises a first detector detecting that a thread engaging part of a balance is located in the vicinity of a forward movement starting point leftward beyond a thread receiving opening of a thread guide plate and an indicator operating on the basis of a detection signal received from the first detector. Thus, the operator can recognize that the thread engaging part of the balance is located in the vicinity of the forward movement starting point leftward beyond the thread receiving opening of the thread guide plate through the indicator. When the operator moves the balance to a position for turning on the indicator, guides a needle thread and thereafter operates the sewing machine, therefore, the thread engaging part of the balance reliably captures and pulls the needle thread also immediately after the sewing machine starts to operate. Consequently, formation of no first stitch (skipping stitch), which is readily caused immediately after the sewing machine starts to operate, is prevented.
