When processing cloth 17 is not configured in assigned position corresponding with " 2 " on cloth pushing table 18 (with reference to Fig. 7 A), the detection signal of optical sensor 32 becomes disconnection (being judged as "No" in step S12).In step S9, control device 9 shows " mistake " this information on the display part 54a of guidance panel 6.In step S10, whether control device 9 decision operation persons have carried out making operation to reset switch 53.If the operator has carried out making operation (being judged as "Yes" in step S10) to reset switch 53,, in step S11, control device 9 rises presser feet 25, returns to step S1 and processes.
Like this, for example, in the time of processing cloth 17 as the operator to the order misjudgment in circulation slit die formula and be configured on wrong position, 9 of control device forbid that sewing moves and report to the police.Therefore, can prevent in advance that the sewing mistake of carrying out tack keyhole seam in the position that should carry out round end keyhole seam or carrying out round end keyhole seam in the position that should carry out tack keyhole seam from occurring.Especially, not there will be in the tack keyhole seam position that does not form buttonhole and form the situation of buttonhole, thereby the phenomenon of the processing cloth 17 of can avoiding waste.
According to such present embodiment, when testing result and the kind of keyhole seam of optical sensor 32 are not corresponding, control device 9 is forbidden the sewing action.Therefore, in predefined order, carrying out the circulation slit die formula of sewing action, can prevent from advance, because of the operator, wrong causing of the configuration appearance of processing cloth 17 is sewn into to the problem on processing cloth 17 by the keyhole of other kinds.
Especially, because the optical sensor 32 that has adopted in the present embodiment reflection-type is used as detector, so can form simply detector and can detect reliably processing cloth 17 whether at the ad-hoc location of cloth pushing table 18.
Because by installing component 31, by optical sensor 32, the mode with position changeable is set on cloth pushing table 18, thus can detect as required the optional position on cloth pushing table 18, and applicable to shape and size (size) different various processing clothes.Now, because the installing hole 18b for fixedly mounting parts 31 forms in the left-right symmetry position of cloth pushing table 18, thus also optical sensor 32 can be transformed to the left side of cloth pushing table 18, applicable to the processing symmetrical situation of cloth (female suit etc.).
In addition, the invention is not restricted to above-mentioned embodiment, it also can do following remodeling, expansion.
Above-mentioned embodiment is exemplified with in circulation slit die formula, repeatedly processing cloth 17 being carried out to the situation of above-mentioned buttonhole stitch 29,29,30 sewing, but is not limited to this.In other words, program is once only carried out in the sewing action that the present invention also carries out a plurality of keyholes seams applicable to the order to set.In other pattern (separately slit die formula etc.), as long as the corresponding relation of clearly processing in advance between the kind of the position of cloth and keyhole seam just can be implemented as described above.Also be not limited to above-mentioned two types with regard to the kind of keyhole seam, also can comprise the various types of keyhole seams such as tack keyhole seam that form buttonhole.
