PROBLEM TO BE SOLVED: To rapidly restart sewing by directly moving an embroidery frame from a present position to a sewing restart position without setting an original position when the sewing is restarted even in the case of the interruption of energization to the exciting coils of X, Y stepping motors for moving a cloth holding frame. SOLUTION: When an energization interruption command is input during the sewing (S11), energization to the exciting coils of the X, Y-axis driving motors is interrupted (S12). When a pattern being sewed at present is re-sewed (S15: Yes) in the energization interruption state, the sewing start position of the pattern being sewed at present is stored as the sewing restart position (S16). When the sewing is restarted by the start operation of a start/stop switch (S17: Yes), the amount of movement from the present position to the sewing restart position, which is the count values of X, Y-direction counters, is calculated (S19). Then, a cloth presser plate is moved at once to the sewing restart position, on the basis of the amount of movement. COPYRIGHT: (C)2008,JPO&INPIT
