摘要

A zigzag sewing machine including a sewing mechanism; a first storage device that stores pattern data that include attribute data and stitch data; a pattern selection section that sequentially selects optional pattern data stored in the first storage device; a second storage device that stores pattern data that have been selected by the pattern selection section as an arranged combinational pattern; a command data insertion section that inserts and adds pause data at an optional position midway of a pattern data string stored in the second storage device; a pause command section that reads out the pause data and that supplies the pause signal to the sewing machine drive unit; and a display device that displays the combinational pattern, the display device further displaying a pause symbol at a position in the combinational pattern where the pause symbol has been inserted and added.

主权项

1. A zigzag sewing machine that sews a combinational pattern, the zigzag sewing machine comprising:
a sewing mechanism that is driven by a sewing machine drive unit, the sewing mechanism forming a stitch pattern by a left-right swing of a vertically reciprocating needle bar mounted with a needle at a lower end thereof and by a forward-rearward feed of a feed dog; a first storage device that stores a plurality of pieces of pattern data including attribute data related to a pattern type and stitch data that controls the left-right swing of the needle bar and the forward-rearward feed of the feed dog; a pattern selection section that sequentially selects optional pattern data from the plurality of pieces of pattern data stored in the first storage device; a second storage device that stores a plurality of pieces of pattern data that have been selected by the pattern selection section as an arranged combinational pattern; a command data insertion section that inserts and adds pause data at an optional position midway of a pattern data string constituting the combinational pattern stored in the second storage device; a pause command section that reads out a pause data that has been inserted and added with the command data insertion section and that supplies the pause signal to the sewing machine drive unit; and a display device that displays the combinational pattern corresponding to the pattern data selected with the pattern selection section, the display device further displaying a pause symbol, the pause symbol corresponding to the pause data that has been inserted and added with the command data insertion section, at a position in the combinational pattern where the pause symbol has been inserted and added.
