Abstract
Stitch data of partial patterns constituting a continuous pattern are stored in a memory in the sewing order with each partial pattern separated from the next. When a trouble occurs, such as a break of the needle thread or the consumption of the bobbin thread, or the user depresses a start/stop switch during sewing of the continuous pattern, the sewing machine is stopped. When the user corrects the trouble and subsequently operates a head search key, sewing is resumed, in response to a starting instruction, from the head of the partial pattern at which the sewing was interrupted.
