Abstract
A sewing machine includes an embroidery data memory unit, a suspension timing selecting unit, and a suspension control unit. The embroidery data memory unit stores embroidery data, and accepts a planned suspension timing, a sewing suspending instruction, and a sewing resuming instruction. The suspension timing selecting unit selects a discontinuous operation that breaks the continuity of seams within the predetermined range before and after the planned suspension timing from the embroidery data. The suspension control unit maintains the deactivation of a sewing-machine motor until the suspending instruction or the resuming instruction is input when the selected discontinuous operation by the suspension timing selecting unit comes during the sewing of embroidery pattern.

- a control unit controlling the frame driving unit and the sewing-machine motor,
- wherein the control unit comprises:
- an input unit accepting, regardless of an advancement of sewing, input of a fixed planned suspension timing, a suspending instruction of sewing, and a sewing resuming instruction;
- an embroidery data memory unit storing embroidery data which describes an operation procedure for forming an embroidery pattern;
- a suspension timing selecting unit selecting an operation which breaks a continuity of seams within a predetermined range before and after the planned suspension timing accepted by the input unit;
- and
- a suspension control unit maintaining, when operation which breaks a continuity of seams re-selected by the suspension timing selecting unit comes, a deactivation of the sewing-machine motor until the suspending instruction or the resuming instruction is input, during the sewing of the embroidery pattern.
