Fig. 5～Fig. 7 is illustrated in each mode state on the described guidance panel 6.On this guidance panel 6, be positioned at the right side of described touch panel 5, be provided with: the power supply to button holing sewing machine M carries out the power switch 30 that ON, OFF use; Execute key 31; Mode switching key 32.On described touch panel 5, be provided with the various information of program number Pr.No that demonstration sends here from control device 7 and parameter Pa etc. and operator to sewing program Pr with make the operated key that parameter Pa sets change usefulness.Therefore, this guidance panel 6 has the function as input unit.

When being in change Licensing Model described later, if by operator's operator scheme switch key 32, then in ON operation each time successively to stitch mode (with reference to Fig. 5) that can automatic sewing, the sewing program change pattern (with reference to Fig. 6) that can change sewing program Pr, can switch the parameter modification pattern (with reference to Fig. 7) that parameter Pa changes of making of sewing program Pr.And, when operation execute key 31 under the state that required mode is presented on the touch panel 5, become the state that in this selected pattern, can carry out various settings.

Wherein, stitch mode is the pattern that automatic sewing was set, can be carried out to operator's opposite joint film-making number.In this stitch mode, as shown in Figure 5, will make display lamp 34a and light, and show the program number Pr.No that sets.In stitch mode, the operator can utilize increasing-and-decreasing key 33a opposite joint film-making number to carry out change setting.Again, this setting makes the sheet number and can count and reduce according to operator's the sheet number of making.In this stitch mode, when operation pedal 4, on processing cloth, form keyhole stitch seam 20 and buttonhole 21 according to the sewing program Pr that sets.

Described sewing program change pattern is the pattern that the operator can select required sewing program Pr.In this sewing program change pattern, as shown in Figure 6, Pr is changed display lamp 34b light, and show the program number Pr.No that sets now.Therefore, increasing-and-decreasing key 33b is operated and can shown program number Pr.No be increased and decreased, be altered to required program number Pr.No, can select by the operator.

Described parameter modification pattern is that the operator can be to the pattern that parameter Pa changes of making of selected sewing program Pr.In this parameter modification pattern, as shown in Figure 7, Pa is changed display lamp 34c light, and show program number Pr.No, the parameter Pa.No set and the setting value of making parameter Pa corresponding with this parameter Pa.No.

And, in this parameter modification pattern, when the operator by increasing-and-decreasing key 33c being operated and when making parameter Pa.No change select required parameter Pa.No, show the setting value corresponding at the downside of parameter Pa.No with this selected parameter Pa.No.Under this state, by the operator increasing-and-decreasing key 33d is operated, just can make the parameter Pa that makes of selection be altered to required numerical value.

Fig. 8 is the block diagram of the control system of expression button holing sewing machine M.Described control device 7 is to accept to send the device that the integral body of the button holing sewing machine M of signal etc. is controlled from the signal of guidance panel 6 and detector described later 51 etc. and subtend drive division.This control device 7 is with the structure of computer 45 as main body, by CPU40, ROM41, RAM42, EEPROM43 (can write and the ROM that deletes electric data), the bus 44 that is connected with these, the formations such as output/input interface 46 that input/output signal is used.

On described output/input interface 46, connecting: drive sewing electric motor 3 usefulness drive circuit 47, drive the drive circuit 48 of swing motor 14 usefulness, drive before and after driving with the used drive circuit 49 of motor 26, driving cutter driving with the drive circuit 50 of solenoid 18 usefulness, whether to installation foot pedal 4 detects the detector 51, described guidance panel 6 of usefulness etc.

In described ROM41, have and a plurality ofly make parameter Pa and utilize guidance panel 6 can write down selectable a plurality of sewing program Pr etc. with reading.In RAM42, storing the various data of pin logarithmic data in making etc.In EEPROM43, can store the operator with rewriting guidance panel 6 is carried out the sewing program Pr of operating and setting and makes parameter Pa, therefore, this EEPROM43 has the function as storage device.Thus, when beginning to make, can reduce sewing program Pr and the manpower that repeats identical change once more and time of making parameter Pa at every turn.

Described programmed protection device 8 is described again.This programmed protection device 8 is to forbid sewing program Pr under certain condition and make the change of parameter Pa and protect the device of usefulness.As shown in Figure 8, pedal 4 has the connector 52 that is electrically connected usefulness with button holing sewing machine M (control device 7), and this connector 52 can be to take off to be installed on the detector of being located on the described sewing machine table 1 51 (shirking).Programmed protection device 8 is made of guidance panel 6, the pedal 4 with connector 52, detector 51, described control device 7 etc.

On the connector 52 of described pedal 4, be provided with the testing circuit 53 that detects usefulness.On described detector 51, be provided with: delivery outlet 54, detect hole 55, with the detection signal delivery outlet 56 of detection signal to control device 7 output usefulness.Under the state that connector 52 is installed on the detector 51, delivery outlet 54 utilizes the detection road 53 of connector 52 by short circuit with detection hole 55.This detector 51, for example, only when power connection, pulse is sent from delivery outlet 54,, whether to detecting that hole 55 is fed back and whether pedal 4 is installed automatically and detected this testing result is sent from detection signal hole 56 to control device 7 as detection signal by 53 pairs of these pulses in detection road.Therefore, detector 51 has the function as checkout gear.

And, control device 7, when power connection (when power switch 30 carries out the ON operation), in the occasion of utilizing 51 pairs of pedals 4 of detector (connector 52) installation (connection) situation on the detector 51 of button holing sewing machine M side to detect (in the occasion that receives the detection signal of expression installment states from detector 51), just set the change prohibited mode for.In this change prohibited mode, make described mode switching key 32 ineffective treatments of described guidance panel 6, remain stitch mode and to sewing program Pr with make parameter Pa and keep regularly.At this moment,, do not switch to sewing program change pattern and parameter modification pattern yet, therefore, just can forbid sewing program Pr and the change of making parameter Pa even mode switching key 32 is operated by the operator.

On the other hand, when power connection, when utilizing detector 51 to detect not installation foot pedal 4, the detection signal of the non-installment state of expression is sent to control device 7, control device 7 is just set the change Licensing Model for.In this change Licensing Model, as mentioned above, make mode switching key 32 validations, and according to by the operator mode switching key 32 being operated, just can carry out switching, the change that allows sewing program Pr and make parameter Pa to sewing program change pattern or parameter modification pattern.And, in this change Licensing Model, forbid stitch mode is changed and forbids the execution of automatic sewing.

Then, also effect and the effect of the button holing sewing machine M of above explanation are described with reference to Fig. 9.The processing sequence that the pattern that (when power switch 30 carries out the ON operation) control device 7 was carried out when the flow table of Fig. 9 was shown in power connection is set.That is, as mentioned above, when power switch 30 carried out the ON operation, the situation of utilizing 51 pairs of detectors whether (connection) pedal 4 (connector 52) is installed detected (step S1).

And, utilizing detector 51 to detect occasion (YES among the step S1) to pedal 4 (connector 52) is installed, utilize control device 7 to set change prohibited mode (step S2) for.On the other hand, utilize detector 51 not detect to be equipped with the occasion (NO among the step S1) of pedal 4 (connector 52), utilizing control device 7 to set change Licensing Model (step S3) for.

Wherein, in the change prohibited mode, as mentioned above, in guidance panel 6, be fixed to stitch mode, utilize operator's operation (operated by foot of pedal 4), make action according to the parameter Pa execution of respectively making of the sewing program Pr that in button holing sewing machine M, sets.This time, with regard in statu quo to being stored in the sewing program Pr among the EEPROM43 and making parameter Pa and set, on processing cloth, according to by make the size that parameter sets (the cutting knife size a) and sawtooth needle gage b, tooth width c, line noose reinforce needle gage etc. and form keyhole stitch seam 20 and buttonhole 21.

And, in this change prohibited mode,, forbid sewing program Pr and the change of making parameter Pa even operator's operator scheme switch key 32 can not carry out the switching to sewing program change pattern or parameter modification pattern.Therefore, in making workshop etc., forbid the operator to sewing program Pr or make parameter Pa optionally (opposite) with gerentocratic intention change, can the parameter Pa that makes that set be kept and can guarantee required sewing quality.Specifically, can prevent that the operator to reduce to the pin number in order enhancing productivity pin number than regulation and to lack and become the big situation of needle gage than regulation.Again, be not limited to like this situation that the pin number is reduced, can also prevent from the parameter Pa that makes of other peoples' relevant with sewing condition button holing sewing machine M is at random changed (for example, strengthening or reduce the needle gage of defined), can prevent to make with the unsuitable parameter Pa that makes.

In contrast, in the change Licensing Model, guidance panel 6 is operated, just can and be made parameter Pa and change sewing program Pr by operator (manager).Therefore, when operator (manager) for example when the kind of making (processing cloth) is replaced etc., to sewing program Pr or make the occasion that parameter Pa changes, in case with the connector 52 of pedal 4 from detector 51 removals, under this state by the power connection ON of the power switch 30 (operation) is become the change Licensing Model, utilize the operation of guidance panel 6, just can be easily to sewing program Pr with make parameter Pa and set change.Be set sewing program Pr after changing and make parameter Pa, just be stored among the EEPROM43.

Again, in this change Licensing Model, owing to forbid stitch mode is changed, become the state that to make, even operate so operator's mistake has been adorned pedal 4, can not begin to make yet, can prevent that the operator is to beginning to make the waste that is shocked and processes cloth, the consumption of useless electric power etc. suddenly.Again, operator (manager) in sewing program Pr or the setting of making parameter Pa after changing, make action in order to carry out, the connector 52 of pedal 4 is installed on the detector 51, in a single day and after making power switch 30 carry out OFF, if once more power switch 30 is carried out the ON operation, just become above-mentioned change prohibited mode, become the state that can make.

Like this, if adopt the button holing sewing machine M of present embodiment, just can effectively prevent to carry out the situation that parameter Pa changes of making not according to Sewing machines manager intention.This occasion is because the change of change prohibited mode and change Licensing Model is with the original pedal that button holing sewing machine had 4 (connector 52), as being to take off that member utilizes and according to having or not of its installation carried out, so can make simple structure.

Again, especially in the present embodiment, in the change Licensing Model, make action, so even, also can prevent to begin suddenly to make in the occasion of the operation of having carried out making beginning mistakenly owing to forbid carrying out.Since be only when power connection, the structure of utilizing the installation of 51 pairs of pedals 4 of detector (connector 52) to detect, so and all the time its situation about detecting is compared, control is oversimplified, with the detection of pedal 4 handled the situation of carrying out as plug-in type compare, can prevent that other control of opposite joint manufacturing etc. from exerting an influence.Remain among the EEPROM43 owing to will set sewing program Pr after changing or make parameter Pa storage, and owing to can be retained to the parameter Pa that makes after in a single day setting next by till the change, so when beginning to make, can reduce the manpower and the time of carrying out identical change again at every turn.Owing to can from a plurality of sewing program Pr, select, just can easily carry out various making so need not carry out complicated setting to required sewing program Pr.
