Claims

[Claims for Utility Model Registration] 1. A stitch forming means including a reciprocating sewing machine needle 5;
a cloth feeding device including a cloth feeding means 6 and a second cloth feeding means 7'3, which can adjust the amount of cloth fed to change the amount of creasing; and a sewing area A~ which is divided into a plurality of continuous sewing areas. a storage means 23 for storing stitch number data and crisscross amount data from the start to the end of sewing corresponding to each sewing area A to F of 1 on the work cloth having F; a first reading means 21 that sequentially reads each data in synchronization with the reciprocating movement of the sewing machine needle 5 from the start to the end of sewing; and a drive means 8 for changing the amount of sew-in, and is suitable for use on a work cloth having a plurality of sewing areas A-F.
In order to command a change in the reading order of each data stored in the storage means 23 in a sewing machine configured to perform sewing by changing the amount of offset in each sewing area from the start to the end of sewing, An operation switch 19 that can be operated by an operator and the first reading means 21 sequentially read each data stored in the storage means 23 from the sewing start to the end in the reverse order starting from the data corresponding to the end of sewing. selectively enabling a second reading means 21 for reading and one of the first and second reading means 21 based on the operation of the operation switch 19; A sewing machine further comprising a control means 21 for supplying data read by the reading means to the driving means 8. 2. The first reading means 21 synchronizes the set-up amount data read from the storage unit 23 with the reciprocating movement of the sewing machine needle 5 in order to interpolate the difference in set-up amount between adjacent sewing areas. The second reading means 21 includes a first means for increasing or decreasing stepwise at a predetermined ratio, and the second reading means 21 reads ratio data based on each data read by the reading means 21 and the first means. a calculation means for calculating the number of stitches corresponding to each sewing area, and a calculation means for calculating the number of stitches data corresponding to each sewing area, and a calculation means for calculating the number of stitches data corresponding to each sewing area, and a calculation means for calculating the number of stitches data read by the reading means. The sewing machine according to claim 1, characterized in that the sewing machine includes means for decreasing or increasing.
