ABSTRACT:
The present disclosure relates to a control device to control a sewing machine which executes a sewing operation using a bobbin thread wound on a bobbin and a needle thread by the drive of the sewing machine motor. The control device includes a sewing restarting unit that restarts the sewing operation after stopping the sewing machine motor in response to a detection of bobbin thread scarcity by a bobbin thread remaining amount detection unit. A permitted sewing amount is preset for the sewing operation restarted after stopping the sewing machine motor and when an actual amount of sewing performed after the stop of the sewing machine motor reaches the permitted sewing amount, information is given by the control device.
