In step B4, the numerical value (numerical value display part P7 go up show numerical value) of judging the data items of current selection whether with+key P8 and-key P9 changed, if do not change then enter step B6.If changed numerical value, then in step B5, upgrade value data corresponding to the data items of selecting, and the displaying contents of change numerical value display part P7, enter step B6.
In step B6, judge whether to have operated data setting switch P 6,, return steps A 5 if operated then in step B7, upgrade reformed data value.If judging does not have operating data configuration switch P6, then return step B2 in step B6.
According to the Sewing machines 100 of the above embodiment of the invention, can set " left cut mouth gap correction value " on request (1c), practicable make otch R about evenly alignment, outward appearance has the buttonhole stitch M of feeling of high class.
Therefore, shrink even cutter mechanism produces sealing after the position of opening buttonhole hole P produces deviation or carries out eyelet, also can be neatly by set " left cut mouth gap correction value " (1c) make otch R about evenly align.
In addition and since set " left cut mouth gap correction value " (1c) can make otch R about evenly alignment, so even the different dress material of thickness also can process the buttonhole stitch M of goodlooking buttonhole.
Shown in Fig. 9 (a), about the otch R of the linearity of buttonhole hole P, go up at the different dress material Y (sewn object) of thickness and to carry out buttonhole stitch M.Shown in Fig. 9 (b), the thickness W1 on otch R right side is thicker than the thickness W2 in otch R left side, about otch R difference in height is arranged.And Fig. 9 (b) is the cutaway view of the buttonhole stitch M that sees from A-A ' direction (Fig. 9 (a) go up shown in).
Shown in Fig. 9 (b), tilt to otch R at the suture X of the thick latasuture system that difference in height dress material Y is arranged, simultaneously, the length a that makes that the length b of inclination compares in the thin side that difference in height dress material Y is arranged grows.And, owing to tilt, can see the inboard, seem that the amplitude of the S2 of latasuture portion is longer, can not get the good buttonhole stitch M of outward appearance.Yet the Sewing machines 100 of present embodiment can (1c) press set value with " left cut mouth gap correction value " and set, and evenly aligns about can be otch R having on the dress material Y of difference in height also.
Shown in Fig. 9 (c), if the eedle of decline 25 can not be guaranteed and otch R between enough compressed gaps, then can produce and interfere with the end of otch R.If particularly the thick side with the dress material Y with difference in height produces interference, can make eedle 25 to the descent direction bending, produce bad phenomenon such as bent needle, bouncing pilotage.Yet the Sewing machines 100 of present embodiment can (1c) be pressed set value with " left cut mouth gap correction value " and set, and can prevent the interference of the end of eedle 25 and otch R, and can reliably prevent bad phenomenon such as bent needle, bouncing pilotage.
And the present invention is not limited only to the foregoing description, can carry out suitable change.
For example, the spectrum data that stores in RAM3 is not limited to content shown in Figure 3, also can store as Figure 10 or content shown in Figure 11.
Spectrum data shown in Figure 10, be for data items " 6 ", and " latasuture portion right cut mouth gap correction value " to gap (1s) correction value between the otch R that becomes buttonhole hole (button hole) and the S2 of latasuture portion set, and comes evenly aliging about otch R.At this moment, " latasuture portion right cut mouth gap correction value " just becomes the compressed gap data.
In addition, as shown in figure 11, for data items " 5 ", set " latasuture portion right cut mouth gap " as gap between the otch R of buttonhole hole (button hole) and the S2 of latasuture portion, for data items " 6 ", set " latasuture portion left cut mouth gap " as gap between otch R and the S1 of latasuture portion.Can distinguish the gap of setting individually between the S1 of left and right sides latasuture portion, S2 and the otch R with this, make otch R about evenly the alignment.At this moment, " latasuture portion right cut mouth gap " and " latasuture portion left cut mouth gap " just becomes the compressed gap data.
In addition, being provided with RAM3 as the storing mechanism that stores spectrum data, also can be the outside Storage Media of picture EEPROM (EEEPROM (Electrically Erasable Programmable Read Only Memo)) or floppy disc.
Method of operating on the quantity of spectrum data, the number of data items, the guidance panel etc. can be carried out suitable change.
In addition, the foregoing description is to have stored a plurality of spectrum datas, and selects one of them to make stitch data, but also can store a plurality of stitch data in storing mechanism.Perhaps, also can store a plurality of spectrum datas and corresponding to the stitch data of each spectrum data.In this case, can be once having selected spectrum data just can automatically specify stitch data.
In addition, as the shape of button hole, being not limited only to buttonhole hole P, also can be other shapes such as finedraw.
In addition, in the scope that does not exceed aim of the present invention, certainly, also can carry out suitable change for concrete thin portion structure.
