Abstract
The present invention aims to speed up of processing necessary at the time of switching between different sewing operation modes. Sewing data supply means supplies sewing data having mixed therein data indicative of different sewing operation modes. The sewing machine sews, based on the sewing data, a string-shaped material to a workpiece with different sewing operation modes mixed. A control device for the sewing machine includes a quick shift process means that controls, at a boundary between the different sewing operation modes and depending on a difference between the sewing operation modes immediately preceding and succeeding the boundary, whether to execute a process for shifting to the succeeding sewing operation mode while keeping a main shaft of the sewing machine rotating (rapid process) or to execute the process for shifting to the succeeding sewing operation mode after temporarily stopping the rotation of the main shaft (normal shift process).
