ABSTRACT:
A sewing machine includes an embroidery frame moving device detachably attachable to a sewing machine body and a control device. An embroidery sewing operation is executable when the embroidery frame moving device is attached to the body, and a normal sewing operation is executable when the moving device is detached from the body. The control device controls the sewing machine in a first stage under only a normal sewing mode in which the normal sewing operation is executed. The first stage ends when a detector detects the embroidery frame moving device initially attached to the body. The control device further controls the sewing machine in a second stage under either the normal sewing mode or an embroidery sewing mode in which the embroidery sewing operation is executed. The second stage starts after the detector has detected the embroidery frame moving device attached to the body.
