CPU44 (S33 when being not detected by the operation of selection end key：It is no) processing is returned to S31.CPU44 is detecting selection section During the operation of any key when sewing machine function sets key and sewing during away from setting key, stopping in sewing machine function setting key (S32：It is), whether the key for judging to detect selection operation in S32 is pitch setting key (S34).CPU44 is being not detected by choosing Select (S34 when pitch sets the operation of key：It is no), whether the key for judging to detect selection operation in S32 is sewing machine when stopping Function setting key (S35).CPU44 (S35 when detecting the operation of sewing machine function setting key when selection stops：It is), aobvious Show shown in portion 11 stopping when function setting screen 110A (reference picture 9) (S36).CPU44 is stitched when being not detected by selection stopping (S35 when machine function of threading sets the operation of key：It is no), function setting screen 110B (reference pictures when sewing is shown on display part 11 10)(S41).Function setting screen 110B is sewing machine function setting screen when function setting screen 110A and sewing during stopping One of 110.

Reference picture 9, Figure 10 illustrate sewing machine function setting screen 110.Sewing machine function setting screen 110 can stop Shi Gongneng setting screens 110A (reference picture 9) and switched between function setting screen 110B (reference picture 10) during sewing.Seam Machine function of threading setting screen 110 includes multiple function keys 112, voltage and shows bar 151 and grade display part 161.CPU44 is in display During stopping during function setting screen 110A, display is " during stopping " (reference picture 9) at switch key 111；The function when showing sewing During setting screen 110B, display is " during sewing " (reference picture 10) at switch key 111.Switch key 111 shows that currently chooses sets The classification of mould-fixed.In the following description, the opening of stepless switch 71 is that stepless switch 71 has reached and CPU44 is performed seam The state of the operational ton for machine function of threading.The closed mode of stepless switch 71 is that stepless switch 71 not up to makes CPU44 perform sewing The state of the operational ton of machine function.As shown in figure 9, function setting screen 110A function key 112 stopped with sewing when stopping The various sewing machine functions that CPU44 can be performed in journey are corresponding.Function setting screen 110A function key 112 during with stopping Corresponding sewing machine function is, for example, that pin correction sewing, tangent line, presser feet lift (alternatively up and down), presser feet and lifted (on temporary transient Rise), bottom line counter resets, half pin correction, backstitch correction, close.The correction sewing of one pin is opened when stepless switch 71 turns into During state, CPU44 drives main motor 13 and work feed motor 23 and the function of only sewing a pin.Tangent line is when stepless switch 71 turns into During opening, CPU44 driving tangent mechanisms and cut off the function of upper thread and bottom line.It is whenever nothing that presser feet, which lifts (alternatively up and down), When level switch 71 turns into opening, CPU44 control presser feets lift electromagnetic component 67 and are alternately performed depression bar 18 and presser feet 17 The function of raising and lowering.It is the CPU44 control presser feets only when stepless switch 71 is opening that presser feet, which is lifted and (temporarily risen), The function of lifting electromagnetic component 67 and make depression bar 18 and presser feet 17 increase.Bottom line counter resets are opened when stepless switch 71 turns into When opening state, CPU44 makes the function of counter resets.Counter calculates the surplus for the bottom line for being wound in peg or spindle.The knot of counter Structure is known, therefore is omitted the description.The correction of half pin is that CPU44 is alternately performed when stepless switch 71 turns into opening The function of the raising and lowering of shank 7.The correction of half pin is the function of the action for the half that CPU44 performs pin correction sewing. Seam correction is that CPU44 drives main motor 13 and work feed motor 23 to convey cloth forwards when stepless switch 71 turns into opening Material 100 and the function of only sewing a pin.Closing is when stepless switch 71 is opening, CPU44 not to be distributed and is held yet The function of capable sewing machine function.Function setting screen 110A function key during stopping shown by operator from display part 11 The key of the desired sewing machine function corresponding with the operational ton of stepless switch 71 is selected in 112.CPU detects the operation of selection key (S36)。

As shown in Figure 10, function setting screen 110B function key 112 and CPU44 institutes energy in sewing operation process during sewing The sewing machine function of enough performing is corresponding.The sewing machine work(that function setting screen 110B function key 112 is corresponding during with sewing Can include as an example stage portion track (unlatching/closing switch), stage portion track (temporarily opening), backstitch, tangent line and Close.Stage portion track (unlatching/closing switching) is the CPU44 alternating cut banks when stepless switch 71 turns into opening The function of the opening and closing of rank portion gesture function.As shown in figure 4, in sewing cloth 100, presser feet 17 crosses stage portion 103 And it is moved to thick thing portion 102 from thin thing portion 101.The cloth thickness of cloth 100 detected by CPU44 is changed into more than defined threshold.Platform Rank portion gesture function is that CPU44 drives cloth conveying teeth 34 by thin thing with movement locus, becomes in cloth thickness when cloth thickness is less than defined threshold During to be more than defined threshold, CPU44 presses the function that thick thing drives cloth conveying teeth 34 with movement locus.With being driven by thin thing with movement locus Dynamic to compare, when being driven by thick thing with movement locus, drive shaft 24 starts the evening on opportunity rotated.Therefore, opened for cloth conveying teeth 34 Begin to horizontal direction act when cloth conveying teeth 34 above-below direction position, with by thin thing with movement locus drive compared with, by thickness It is higher when thing is driven with movement locus.Therefore, sewing machine 1 thick thing portion 102 can be firmly clamped in cloth conveying teeth 34 and presser feet 17 it Between and convey thick thing portion 102 in the horizontal direction, cloth conveying teeth 34 can be reduced relative to the possibility that cloth 100 skids.Stage portion Track (temporarily opening) is the function that CPU44 makes stage portion gesture function to open only when stepless switch 71 is opening. Backstitch is that CPU44 drives main motor 13 and work feed motor 23 to convey cloth forwards when stepless switch 71 turns into opening 100 and the function that is sewed.Identical function during function setting screen 110A when tangent line and closing are with stopping.Operator is certainly Select to want the operation with stepless switch 71 in function setting screen 110B function key 112 during sewing shown by display part 11 Measure the key of corresponding sewing machine function.CPU detects the operation (S41) of selection key.Function setting screen 110A and sewing during stopping Shi Gongneng setting screens 110B has determination key 113 and end key 114.Determination key 113 is directed to by selected by function key 112 The function of selecting, determines that stepless switch 71 turns into the key of operational ton of opening.End key 114 is to terminate to set sewing machine function Determine the key that the sewing machine function in picture 110 is set.

Return to the explanation of setting mode treatment.As shown in fig. 7, function setting screen 110A is shown when will stop in S36 After on display part 11, CPU44 detects magnitude of voltage V (S37) corresponding with the operational ton of stepless switch 71.Operator is while see Examine voltage and show bar 151 and grade display part 161, while operation stepless switch 71 makes up to desired operational ton.CPU44 bases Judge whether to detect the operation (S38) of selection end key 114 in the output of touch panel 16.CPU44 is being not detected by (the S38 during operation of selection end key 114：It is no), the output based on touch panel 16 and judging whether detects selection and determined The operation (S39) of key 113.CPU44 (S39 when being not detected by the operation of selection determination key 113：It is no) processing is returned to S36. CPU44 (S39 when detecting the operation of selection determination key 113：It is), generation makes the function that selection operation is detected in S36 Data are as the first correspondence obtained from sewing machine function corresponding to key 112 is corresponding with the magnitude of voltage V detected in S37 Data 95 (reference picture 11), and (S40) is stored in storage device 49.CPU44 makes processing return to S36.For example, working as CPU44 During the operation for the function key 112 for detecting selection one pin correction sewing, the function key 112 that a pin just is corrected into sewing is confounded black and white Color is shown (S36, reference picture 9).(S37), the operational ton of stepless switch 71 when operator operates stepless switch 71 Change.CPU44 changes the position of the right-hand member 154 of operational ton display part 153 and progress according to the operational ton of stepless switch 71 Display.Operator can confirm the operational ton of stepless switch 71 by the position of the right-hand member 154 of operational ton display part 153.Behaviour Author determines to perform the operational ton that pin correction is sewed on one side while confirm the position of the right-hand member 154 of operational ton display part 153, Then (the S39 of determination key 113 is selected：It is).For example, operator occasionally wants to be set as that the operational ton in stepless switch 71 shows from grade Show and pin correction sewing is performed when the 2nd grade in portion 161 enters 3 grade.In this case, as shown in figure 9, operator grasps Make stepless switch 71 so that then the right-hand member 154 of operational ton display part 153 selects determination key 113 positioned at the upside of the 3rd grade. CPU44 is judged as detecting the operation (S39 of selection determination key 113：It is).As shown in figure 11, CPU44 generation make the 3rd grade with I.e. on magnitude of voltage V V3≤V≤V5 scope magnitude of voltage with as sewing machine function a pin correct sewing it is corresponding Obtained from data as the first corresponding data 95, and be stored in storage device 49 (S40).When operator is with same operation It is determined that when performing the operational ton of other each sewing machine functions, CPU44 makes each sewing machine function corresponding with magnitude of voltage and as One corresponding data 95, and (S37~S40) is stored in storage device 49 successively.CPU44 is detecting selection end key 114 (S38 during operation：It is) processing is returned to S31.

After function setting screen 110B during sewing is shown on display part 11 in S41, CPU44 perform S42~ S45.S42~S45 is processing same with S37~S40 respectively, therefore is omitted the description.

For example, when CPU44 detects the operation for the function key 112 that selection is backstitched, just the function key 112 backstitched is overturned Black-white colors are shown (S41, reference picture 10).For example, operator occasionally wants to be set as the operational ton in stepless switch 71 Perform and backstitch when entering 4 grade from the 3rd grade of grade display part 161.As shown in Figure 10, operator's operation stepless switch 71 cause the right-hand member 154 of operational ton display part 153 to be located at the upside of the 4th grade, then select determination key 113.CPU44 is judged as Detect the operation (S44 of selection determination key 113：It is).As shown in figure 11, CPU44 generations make magnitude of voltage V more than 4th grade The magnitude of voltage of namely V4≤V≤V5 scope and as sewing machine function backstitch it is corresponding obtained from data as first Corresponding data 95, and (S45) is stored in storage device 49.When operator determines to perform other each sewing machines with same operation During the operational ton of function, CPU44 makes each sewing machine function corresponding with magnitude of voltage and deposited as the first corresponding data 95, and successively It is stored in storage device 49 (S41~S45).CPU44 (S43 when detecting the operation of selection end key 114：It is) return processing Return to S31.

As shown in Figure 7, Figure 8, CPU44 detects (S34 when selection pitch sets the operation of key in S34：It is), in display Pitch setting screen 120 (reference picture 12), determination key 121 and end key 122 (S46) are shown in portion 11.The explanation section of reference picture 12 Away from setting screen 120.Pitch setting screen 120 be with pitch variation amount [%] be the longitudinal axis, using the operational ton of stepless switch 71 as The curve map of transverse axis.Storage device 49 is stored with the pitch (hereinafter referred to as benchmark pitch) as benchmark.In the present embodiment, As an example, its direction for conveying cloth 100 of benchmark pitch is rear, and pitch is 2mm.Benchmark pitch is pitch variation amount 100%.Therefore, it is 4mm that pitch variation amount 200%, which represents pitch,.Negative pitch variation amount represents to convey cloth 100 forwards. For example, the direction that pitch variation amount -100% represents conveying cloth 100 is front, pitch is 2mm.The operation of stepless switch 71 Measure each operational ton of the scope of the grade 1~4 of 1~4 corresponding grade display part 161.That is, 1~4 point of the operational ton of stepless switch 71 The magnitude of voltage V of each grade of the grade 1~4 of other corresponding grade display part 161 scope.Corresponding V1≤V ＜ the V2 of operational ton 1.Together Sample, the corresponding V2≤V ＜ V3 of operational ton 2, the corresponding V3≤V ＜ V4 of operational ton 3, the corresponding V4≤V of operational ton 4≤V5.Operator passes through The desired position of pitch setting screen 120 is specified, can be set as making the desired operational ton of stepless switch 71 and desired Pitch variation amount is corresponding.Determination key 121 is the setting to the operational ton of stepless switch 71 and the corresponding relation of pitch variation amount Make the key of determination.End key 122 is the key for terminating to set the pitch in pitch setting screen 120.

Return to the explanation of setting mode treatment (reference picture 8).Outputs of the CPU44 based on touch panel 16 and judge whether inspection The operation (S47) of selection end key 122 is measured.CPU44 (S47 when being not detected by the operation of selection end key 122：It is no), Output based on touch panel 16 and judge whether to detect the instruction (S48) of specified pitch variation amount.Specify pitch variation The instruction of amount refer to longitudinal direction line 129A in the curve map of constant pitch setting screen 120 (reference picture 12), 129B, 129C, The operation of the position at least one line in 129D.Longitudinal direction line 129A~129D represents the operational ton of stepless switch 71 respectively 1~4.CPU44 (S48 when being not detected by the instruction of specified pitch variation amount：It is no), judge whether to detect selection determination key 121 operation (S49).CPU44 (S49 when being not detected by the operation of selection determination key 121：It is no), processing is returned to S47. CPU44 (S48 when detecting the instruction of specified pitch variation amount：Be), detect instruction position (longitudinal direction line 129A, On 129B, 129C, 129D) display such as asterisk (S50).CPU44 makes processing return to S47.CPU44 is detecting selection determination (the S49 during operation of key 121：It is), generation makes the pitch variation amount obtained in S48 and the voltage corresponding to the pitch variation amount Data obtained from value V is corresponding are stored in storage device 49 (S51) as the second corresponding data 96 (reference picture 15). CPU44 makes processing return to S47.

As shown in figure 13, for example, when operator indicates section on the operational ton 1 (on longitudinal direction line 129A) of stepless switch 71 (S48 during away from the position that variable quantity is 100%：It is), pitch variation amounts of the CPU44 on longitudinal direction line 129A is 100% position Put display asterisk 123A (S50).Then, when operator indicates on the operational ton 4 (on longitudinal direction line 129D) of stepless switch 71 When pitch variation amount is 40% position, star is shown on the position of pitch variation amounts 40% of the CPU44 on longitudinal direction line 129D Number 123B, and show line segment 124A (S50) obtained from link asterisk 123A and asterisk 123B.Operator is by confirming longitudinal direction Line 129A, 129B, 129C, 129D and line segment 124A intersection point, and confirm the operational ton and pitch variation amount of stepless switch 71 Corresponding relation.(the S49 when operator selects determination key 121：It is).As shown in figure 15, CPU44 generates one group and is used as the second correspondence The pitch of data 96 sets 1 (S51).As shown in figure 13, longitudinal direction line 129A, 129B, 129C, 129D and line segment 124A intersection point The pitch variation amount at place is respectively 100%, 80%, 60%, 40%.CPU44 envoy is away from variable quantity 100% and V1≤V ＜ V2, section Divide away from variable quantity 80% and V2≤V ＜ V3, pitch variation amount 60% with V3≤V ＜ V4, pitch variation amount 40% and V4≤V≤V5 Data are not obtained accordingly.Therefore, CPU44 makes the magnitude of voltage V and pitch phase in the grade 1~4 of the operational ton of stepless switch 71 Correspondence, generation Figure 15 pitch setting 1.CPU44 makes processing return to S47.

As shown in figure 14, for example, operator indicates that pitch becomes in the operational ton 1 (on longitudinal direction line 129A) of stepless switch 71 Change amount is 100% position, and the position that pitch variation amount is -100% is indicated on operational ton 4 (on longitudinal direction line 129D). Pitch variation amounts of the CPU44 on longitudinal direction line 129A is 100% position display asterisk 123A, on longitudinal direction line 129D Pitch variation amount is -100% position display asterisk 123C.CPU44 displays link line obtained from each asterisk 123A, 123C Section (S50).When operator further indicates the position that pitch variation amount is -40% on operational ton 2 (on longitudinal direction line 129B) When, pitch variation amounts of the CPU44 on longitudinal direction line 129B is -40% position display asterisk 123D, and shows link asterisk Line segment 124B obtained from 123A, 123D and link line segment 124C (S50) obtained from asterisk 123D, 123C.CPU44, which is eliminated, to be connected Tie line segment (S50) obtained from asterisk 123A, 123C.The pitch of longitudinal direction line 129A, 129B and line segment 124B point of intersection becomes Change amount is respectively 100%, -40%, the pitch variation amount difference of longitudinal direction line 129C, 129D and line segment 124C point of intersection For -70%, -100%.As operator's selection determination key 121 (S49：It is) when, CPU44 generation pitches setting 2, and be stored in In storage device 49 (S51).Pitch setting 2 is to set 1 one group of second different corresponding datas 96 from pitch.Specifically, save It is envoy away from variable quantity 100% and V1≤V ＜ V2, pitch variation amount -40% and V2≤V ＜ V3, pitch variation away from setting 2 One group second pair obtained from amount -70% is corresponding with V3≤V ＜ V4, pitch variation amount -100% and V4≤V≤V5 difference Answer data 96.Pitch as shown in figure 15 sets 1, pitch setting 2, and storage device 49 can store multiple pitches settings.
