In Figure 18, circular wall 90a forms described case zone 90, described circular wall 90a and described case shell 87 whole formation case shell 87 in the left side.The bobbin 82 that is seated in the described case zone 90 is installed to the axle 90b of described case shell 87 and is had this 90b to support pivotally.The line 99 that extends from described bobbin 82 from the line that is formed on described circular wall 92 by opening 90 from the top hole that is formed on described hollow needle 81 that is fit into by the backflow disease-prevention institutions 92.Described line 99 is from the lower end of described hollow needle 81.The foreign volume that is pulled to sewing box 5 is little dark color around the upper thread 99 on the described bobbin 82.The line hole shape of described hollow needle 51 becomes described line 99 can pass this hollow needle 81.When being drawn out, the lower end of hollow needle carries out sewing operation at the line 99 of length-specific.

Protective element 83 can cover between position and a retracted position at one and move, cover the tip of hollow needles 83 at described covering position protective element 83, and described retracted position place state protective element 83 from cover the position be withdrawn into above so that described hollow needle 81 can pass work fabric 70.Protective element 83 is preserved described work fabric 70 also as a presser feet when sewing.Described protective element 83 comprises a cap 83a and a guiding section 83b, and described guiding section extends upward from the right-hand member of described cap 83a.Described cap 83a and guiding section 83b are formed a part by integral body and form described protective element 83.

Described cap 83a is formed with a pin by hole 83c, and hollow needle 81 can vertically be guided by case shell 86 by the described guiding section 83b of hole 83c. movably by this pin.Described presser feet [84 is inserted between described guiding section 83b. and the case shell 86.Protuberance 83d who protrudes left is arranged on the middle part of described guiding section 83b on above-below direction in Figure 18.Under the state of described protuberance 83d near the upper end of a rib 86d, described protective element 83 is in described covering position, and described rib 86d guides described guiding section 83b on above-below direction.In addition, the tip of described hollow needle 81 is positioned at pin by within the 83c of hole, makes the tip of hollow needle 83 be covered with by the described covering 83a of portion.When described protective element 83 upwards moves with respect to described hollow needle 81, described protective element 83 just is in described retracted position.Therefore, described hollow needle 81 passes described pin by the bottom protrusion of hole 83c from described cap 83a.

Shown in Figure 18 to 20 and 25 to 27, motion forbids that mechanism 85 has the middle part that a motion inhibit element 100 is arranged within the case shell 86 left side and right top and the bottom.Motion inhibit element 100 comprises a vertical hinge portion 100a; A sticking department 100b is arranged on the left side of hinge portion 100a; With an engaging piece 100c, remove pin 43 engagements with lock, and be arranged on the right of described hinge portion 100a.Vertical hinge portion 100a, sticking department 100b and engaging piece 100c overall structure form the structure of an integral body.In motion inhibit element 100, described hinge portion 100a supports described case shell 86 rotationally, rotates around described hinge portion 100a so that parts 100 are forbidden in described motion.Described motion forbids that parts 100 can not move vertically.

Lock part 100b is long on above-below direction.The bottom of lock part 100b is abutting the upper surface of the protuberance 83d that is in the protective element 83 that covers the position substantially, that is, the lower surface of protuberance 83d is abutted by the upper surface of rib 86d.At this state, lock part 100b is between the rib 86e and protuberance 83d in the box body 80.Therefore, protective element 83 is locked in and covers the position, can not move up.Motion stationary apparatus 100 can turn round between a latched position (referring to Figure 25) and a non-locked position (referring to Figure 26), shifts out from the path that moves up and down of the protuberance 83d between rib 86e and 86d at the lock part 100b of described non-locked position place.Therefore, when motion stationary apparatus 100 is in the non-locked position place, be pushed upwardly if protective element 83 overcomes the elastic force of coiling compression spring 84, then protective element 83 can be moved.When sewing box 5 moved to sewing position by swing arm 40 mobile, protective element 83 just was pushed upwardly.At that time, the pin lid is urged needle plate 31d by work fabric 70 (referring to Fig. 8), and described needle plate has the hole that a hollow needle 81 can pass, and this hole is formed on the bracing frame 31.

One is reversed spring 100d and externally is connected to hinge portion 100a.Described motion inhibit element 100 is pushed to latched position pivotally by the described spring 100d that reverses.Be connected to the state of described sewing device main body 2 at described sewing box 5, described motion inhibit element 100 is maintained at latched position.The antetheca of case shell 86 is formed with an opening 86f with respect to described engaging piece 100c.When described motion inhibit element 100 is in latched position, described engaging piece 100c protrudes to the outside from opening 86f.

As shown in figure 27, described opening 86f extends to the lower wall of described case shell 86.The bottom of described engaging piece 100c is formed with a tapered portion 100e, and this tapered portion outwards and be inclined upwardly.As mentioned above, described lock is removed pin 43 and is set to described Rocker arm 40.When described sewing box 5 is connected to described swing arm 40, described lock is removed pin 43 enters described opening 86f and meshes described engaging piece 100c from the bottom tapered portion 100e.As a result, described motion is forbidden that parts 100 overcome and is reversed the motive force that spring unloads 100d and rotate from the latched position to the unlocked position, so that described protective element 83 is unlocked and can moves up in above-mentioned mode.

As mentioned above, be not connected to the state of described sewing device main body 2 at sewing box 5, described motion inhibit element 100 forbids being in protective element 83 the moving from this position of described covering position.When the state that is connected to sewing device main body 2 at described sewing box 5, described protective element 83 is allowed from described covering position and is moved to described retracted position.

Shown in Figure 18 to 20, the described excessive rotation disease-prevention institutions 91 have: a contact 101, and this contact can contact one of flange 82b of described bobbin 82; One is reversed spring 102, and this reverses the described contact 101 of spring 102 compressings and is pressed on the described flange 82b.By being created in frictional force effect between described contact 101 and the described flange 82b, thereby bobbin 82 is prevented from the excessive feeding of crossing the anti-principal vertical line 99 of the component of rotation on the online direction of the supply.Described contact 101 is supported rotationally by the axle 103 that the described case of a vicinity zone 90 is provided with in described case shell 86.Described axle 103 is equipped with one and reverses spring 102.By passing an opening 90d who is formed on circular wall 90a, the tip contact of described contact 101 is arranged in the flange 82b of described case zone 90 bobbins 82.

As Figure 18, shown in 19,21 and 28, the described backflow disease-prevention institutions 92 have two prevention elements that reflux, and they are flat springs 106 of a guide pins 105 and a described guide pins 105.Between described guide pins 105 and described flat spring 106, a line is set by portion 107, this line is a minimum gap by portion 107.The line 99 of pulling out from described bobbin 82 passes through portion 107 through described line.Because described guide finger 105 of contact and flat spring 106, described line 99 has been applied in the friction drag.

The two ends of described guiding 105 are fixed among the sleeve 87c, and described sleeve 87c is formed on to open and covers 87 right part.Thereby flat spring 106 is inserted into described opening and covers the 87 described guide pins 105 that promote to be in to the right with downward-sloping posture.A tiny 105a with minor diameter is formed on the middle part of described guide pins 105.Line is formed by described tiny 105a and flat spring 106 by portion 107.Thereby the described line of process applies a suitable frictional resistance by the line 99 of portion 107, and described line 99 can guarantee that guiding enters described hollow needle 81.

Shown in Figure 18 to 20 and 29, be not connected to the state of described sewing device main body 2 at described sewing box 5, locking mechanism 93 integrally locks described opening and covers 87 and enter case shell 86.Described locking mechanism 93 has the Lock Part 110 that is arranged on case shell 86 the right.Described Lock Part 110 is by with

hinge portion

110a, 110b, and a connecting portion 110c, one is connected that the 110d of portion is whole to be formed the structure of an integral body and form.Described

hinge portion

110a, 110b is supported rotationally by a vertical outrigger shaft.Described Lock Part 110 can be changed its position between latched position (seeing Figure 18) and unlocked position (seeing Figure 19).

Described locking member 110 is conditioned its vertical motion.Lock Part 110 reverses spring 111 by one and is pushed to described latched position.At Figure 18, described connecting portion 110c protrudes to the right from the top of locking member 110.Described connecting portion 110d protrudes to the right from locking member 110 bottoms.Described connecting portion 110c and the described 110d of portion that is connected can be respectively from opening 86g, and 86h protrudes to the left side, described

opening

86g, and 86h is formed on the rear wall of connection dimple 86a and the top of antetheca.

When described sewing box 5 was not connected in the described swing arm 40, described opening covered 87 and is positioned at described closed position.At this state, the connecting portion 110c that is positioned at the described locking member 110 of latched position is engaged to and is connected the 87d of portion, described be connected portion in Figure 18 from top from can open cover 87 antetheca left (inwardly) protrude.Correspondingly, described opening covered 87 and can not be moved up with respect to described case shell 86, and is overally locked to described case shell 86 in described closed position.

When described sewing box 5 was connected to described swing arm 40, as mentioned above, because the connection dimple 86a of described case shell 86 meshes the connecting pin 42 of described swing arm 40, the 110d of the portion that is connected of described locking member 110 is oppressed and moved to connecting pin 42 to the right.Therefore, described Lock Part 110 is switched to unlocked position from latched position.At this state, the connecting portion 110c that is positioned at the described locking member 110 of unlocked position breaks away from from the described 87d of portion that is connected.Locking is disengaged, and covers 87 and can move up with respect to case shell 86 thereby can open.

Usually, can open 87 states in the closed position that cover, sewing box 5 separates from described swing arm 40.Therefore, by after separating just, in described latched position, described opening cover 87 quilts and is overally locked to described case shell 86 at described sewing box 5.If cover the 87 state sewing boxes 5 that are not in described closed position and separate from described swing arm 40 can opening, along with described opening covered 87 release, described locking member 110 just is switched to latched position.Yet,, cover 87 and be rotated to the closed position by the described motive force effect of reversing spring 88 so can open because the tapered portion that is tilted to the left is formed on the left part of the connecting portion 110c of locking member 110.At that time, be connected the 87d of portion and move described locking member 110, so that described opening covered 87 and can be switched to described closed position by the interim compressing of described tapered portion and towards unlocked position.

Hereinafter, with reference to Figure 30 to the 37 pair of sewing operation of carrying out at sewing device 1 be formed on work fabric 70 needle trackings by this sewing operation and be described.

Be connected to the state of sewing device main body 2 at the embroidery frame 4 that has work fabric 70 and sewing box 5, sewing box 5 is moved vertically by box driving mechanism 12.At that time, hollow needle 81, protective element 83 (when protective element 83 during), bobbin 82 and excessively rotate the disease-prevention institutions 91 along with the case shell moves up and down away from work fabric 70.Yet, can open and cover 87 and be fixed on sewing device main body 2, cover 87 hardly along with the backflow disease-prevention institutions in it of the backflow disease-prevention institutions in being arranged on 92 move up and down so that can open.

When sewing box 5 was connected to swing arm 40 and first sewing operation and is performed, as shown in figure 30, a segment length of line 99 was pulled out from the lower end of hollow needle 81.When case shell 86 when this state descends, as shown in figure 31, at first, protective element 83 grips work fabric 70 as a presser feet, this moment, line 99 was positioned on the work fabric 70.Because protective element 83 is gripping described work fabric 70, stops substantially so described protective element 83 becomes.Then, hollow needle 81 thrusts described work fabric 70 with respect to protective element 83 declines.At this moment, in the moment that hollow needle 81 thrusts described work fabric 70, hollow needle 81 is substantially perpendicular to described work fabric 70.The end of hollow needle 81 is positioned at the end of described sewing box 5 in the oscillation center side of swing arm 40.

When hollow needle 81 thrusts elastic film parts 73, from described hollow needle 81 extend and the line 99 that thrusts described work fabric 70 by one because the line confining force that the elasticity of elastic film parts 73 produces maintenance.At this state, when hollow needle 81 (bobbin 82 and excessively the rotation disease-prevention institutions 91) when further descending, line 99 overcomes the opposing that is produced by the excessive rotation disease-prevention institutions 91 and the backflow disease-prevention institutions 92 and leads the power of rubbish line 99 and be drawn out from bobbin 82, and forms a Freezone 75 at the reverse side of work fabric 70.At this moment, half of line 99 that forms described Freezone 75 is positioned within the described hollow needle 81.

The resistance of being led rubbish line 99 by the opposing of the excessive rotation disease-

prevention institutions

91 and 92 generations of the backflow disease-prevention institutions is littler than line confining force.Therefore, when described hollow needle 81 thrusts work fabric 70 and drops to a lower position, the line 99 that extends from hollow needle 81 is not almost led rubbish by the reverse side towards work fabric 70, and line 99 is pulled out from bobbin 82.Therefore, described Freezone 75 forms in reverse side one side of work fabric 70.If the line 99 that extends from hollow needle 81 is maintained between protective element 83 and the work fabric 70, line 99 just can not be by the reverse side tractive towards work fabric 70 before hollow needle thrusts in the work fabric 70.

Then, when described case shell 86 moves up, shown in figure 32, hollow needle 81 rises from the lower position, and the tip of hollow needle 81 is extracted from work fabric 70.Then, the work fabric 70 that keeps by protective element 83 effect that can not be under pressure, protective element 83 is along with hollow needle 81 rises to upper limit position.At this moment, when line 99 is fixedly connected between the backflow disease-prevention institutions 92 that stop at some positions and the work fabric 70, have only hollow needle 81 to rise.The Freezone 75 that is formed on the work fabric reverse side is held, and whole Freezone 75 is exposed.When hollow needle 81 moved on to described upper limit position, the bobbin 82 and the excessive disease-prevention institutions 91 of rotating also moved on to described upper limit position.At that time, line 99 is not moved to described hollow needle 81 from the backflow disease-prevention institutions 92, and the described backflow disease-prevention institutions 92 and the excessive disease-prevention institutions 91 of rotating apply the opposing traction force for line 99.Correspondingly, 99 changes of the line between bobbin 82 and backflow mechanism 92 are loosened.

Then, as shown in figure 33, when work fabric 70 was moved in the horizontal direction, line 99 was involved by the line confining force, because the line 99 that extends from hollow needle has work fabric 70 to keep, so the loose line 99 between the bobbin 82 and the backflow disease-prevention institutions 92 is by the backflow disease-prevention institutions 92 tractives.At that time, the line confining force that is produced by work fabric 70 pulls up much larger than the opposing that is produced by the backflow disease-prevention institutions 92, and making does not have possibility to extract the line 99 that forms Freezone towards hollow needle 81 sides.

After work fabric 70 was moved in the horizontal direction, described case shell 86 descended.As shown in figure 34, protective element 83 is keeping work fabric 70, and hollow needle 81 penetrates into work fabric 70.When hollow needle 81 drops to the lower position from upper limit position, the loose line of residue between the bobbin 82 and the backflow disease-prevention institutions 91 is pulled, and line 99 is drawn out from described bobbin 82 then.The line 99 of pulling out has been applied the power of opposing tractive by the excessive rotation disease-prevention institutions 91 and the backflow disease-prevention institutions 92.As mentioned above, the tractive resistance is more less than the line confining force of work fabric 70.In addition, line 99 can be pressed on the work fabric 70 by protective element 83.Correspondingly, form a new Freezone 75 and can from work fabric 70, not extract previous Freezone 75.

Then, as shown in figure 35, hollow needle 81. and protective element 83 rise.Then, carried out repeatedly as the operation of Figure 33 to 35.As described above, each sewing operation line 99 is all stayed on the work fabric 70 by the elastic reaction of work fabric 70, forms many Freezones 75 in reverse side one side of work fabric 70 by line 99, as shown in figure 36.Therefore, the needle tracking of formation embroidery decorative pattern 76 forms on the surface of work fabric 70.When double-faced adhesive tape 77 is used the reverse side that Freezone 75 is fixed on work fabric 70, pattern fabric 78 shown in Figure 37 just is formed.

Correspondingly, Freezone 75 can not come off, and makes line 99 need do not fixed by the line of other line or previous needle tracking and follow-up needle tracking.The embroidery decorative pattern 76 that forms on work fabric 70 is very stable, and can not decoherence.Pattern fabric 78 can be connected on various things such as the badge by double-faced adhesive tape 77.Except double-faced adhesive tape 77, also can be coated with one deck bonding agent at the reverse side of work fabric 70.Can form a band by sticker, described band can be used for Freezone 75 is fixed on the reverse side of working substance 70.

In the reverse side of work fabric 70, many Freezones 75 are arranged.Correspondingly, when described double-faced adhesive tape 77 is glued to the reverse side of work fabric 77, on double-faced adhesive tape 77, can produce uneven.When work fabric 70 is adhered on the clothes as a badge by described double-faced adhesive tape 77, because clothes is soft, so described badge comes off easily.Yet the adhesion of work fabric 70 is owing to the roughness of double-faced adhesive tape 77 is improved.Described roughness is formed with the double-faced adhesive tape that is used by the Freezone 75 that depends on wire material or every several Freezone 75.

The needle tracking that is formed by hollow needle 81 will be described below.

When hollow needle 81 thrusts described work fabric 70, shown in Figure 38 A, the cut surface 165 of an arc of 169 formation around the center shown in Figure 38 B.With respect to the tip of hollow needle 81, the center 169 of described arc cut surface 165 is positioned at a side opposite with swing arm 40 oscillation centers.At first, the centre substantially on described cutting surface 165 is thrust at the tip of hollow needle 81.Then, described hollow needle 81 moves and passes described work fabric 70 along an arc downwards, thereby forms arc cutting surface 165.Line is remained in the work fabric 70 by arc cutting surface 165.

The oscillation center of the tip of hollow needle 81 and swing arm 40 correspondingly is positioned at the left side and the right (at the bearing of trend of swing arm 40).When some needle tracking is filled up in a zone,, fabric sews by being put the cart before the horse.As shown in figure 39, one of the both direction shown in a in the drawings of preferably sewing (along sewing device main body 2 preceding to the back or the back to one of preceding direction) carry out, this direction is perpendicular to the bearing of trend of swing arm 40.That is, in the relative motion that a certain direction continues, hollow needle 81 and embroidery frame 4 are parallel to the arc shooting direction and move.Therefore, the tangent line in cutting 165 in the middle of the arc is not orthogonal to the orientation on described cutting surface, and this is arranged on the fore-and-aft direction and forms in order.Therefore, many cut surfaces 165 formation in succession one by one.If the bearing of trend at Rocker arm 40 is carried out sewing, line 99 can be by the tip cutting of hollow needle 81 so.

For from the most advanced and sophisticated portable cord 99 of hollow needle 81 as shown in figure 31, the needle tracking position need change with respect to the bearing of trend b of Rocker arm 40 on one of the fore-and-aft direction that 5 degree roughly arrive sewing device main bodys 2.That is, the needle tracking position is moved from the end of hollow needle 81.As described above, embroidery frame driving mechanism 11 is controlled to the cutting of anti-principal vertical line.In order to finish above-mentioned operation, be used for coming a control program of mobile embroidery frame 4 (work fabric 70) to be set up by control sewing device 1 with respect to hollow needle 81, described control program can be stored among the ROM13b of controller 13.The part of control program can be stored in the recording medium, such as a DVD, so that described control program can be by such as game machine 6, and the controller 13 of sewing device 1, personal computer is read.

According to above-mentioned sewing box 5, at the two states that sewing box 5 is connected to described sewing device main body 2 and throws off from described sewing device main body 2, protective element 83 can cover the tip of hollow needle 81 at least.In addition, being in the protective element 83 that covers the position can be forbidden mechanism's 85 effects and be under an embargo and move from this covering position by motion.Correspondingly, particularly, when described sewing box 5 is connected to or when sewing device main body 2 was thrown off, the infringement to clothes that produces owing to hollow needle 81 can be prevented from, described sewing box 5 can be controlled reliably easily.

Hollow needle 81 is provided with regularly, so that the most advanced and sophisticated side part of hollow needle 81 is protruded from described box main body 80.By hollow needle 81 reciprocating motion vertically, hollow needle 81 passes work fabric 70, and sewing operation is performed.In addition, protective element 83 also uses as a presser feet.Therefore, the small-sized sewing box 5 with simple structure can obtain.In addition, reciprocating mechanism can simplify with hollow needle 81 (sewing box 5), thereby helps the miniaturization of sewing device 1.

The structure of sewing box 5 can be done part as described below and change.The structure of protective element 83 becomes, and the position of protective element 83 can cover between position and a retracted position at one and manually change.In this case, protective element 83 can be removed to the presser feet [84 that covers the position compressing.Conventional sewing needle can be used and replace described hollow needle 81.

Excessively the rotation disease-prevention institutions 91 are configured to, and frictional resistance is applied to flange 82b by support for bobbin or other elements or part, are not only obtained by reversing on the flange 82 that contact 101 that spring 102 promotes is pressed against bobbin 82.In the described backflow disease-prevention institutions 92, a dimple can be formed on flat spring 106, provides a line by portion, replaces forming in described guide pins 105 tiny 105a.

Replace to form described opening 86c, described case shell 86 and described opening covers 87 and can be formed by a transparent or semitransparent material one of at least and make the volume residual of line 99 to cover 87 and visually confirmed through case shell 86 and/or described opening.Can line color instruction unit 87b be set at the position beyond the top surface of the lid opened 87 of described box main body 80.As described line color instruction unit, box main body 80 can be included in described box main body 80 in be wound on the color of line 99 of described bobbin 82 identical/similar color partially or even wholly dyes.

Hereinafter, the sequence of operations of above-mentioned sewing device 1 describes with reference to flow process Figure 43 and 44.Illustrate as Fig. 1, suppose that sewing device 1 is connected to described game machine 6 by stube cable, the DVD120 storage data of Figure 42 are installed among the DVD driver 6d of described game machine 6..Game machine 6 is connected to described CRT8 by stube cable.

At first, a kind of embroidery pattern uses the controller 7 selected/editors of game machine 8 to be careful the screen on CRT8 simultaneously.Described embroidery pattern can be chosen/editor, and not with the power supply opening of described sewing device 1.

As shown in figure 43, in the controller of game machine 6, when the power supply of game machine 6 is opened, the control beginning.In initialization (S1) (S represents a step) afterwards, the data among the DVD120 (such as the selected control program of pattern, pattern editor control program, and display control program) are read (S2).Then, in the selected processing of pattern (S3), an embroidery pattern of wanting can choose from the various embroidery patterns that are stored in the described DVD120.In pattern editing and processing (S4), a selected embroidery pattern can be by editor (for example, amplify, reduce, merge, upset).

Selection/the editor of embroidery data is by a predetermined button (S5 of operation control 7; Be) finish.Then, when accepting data (S6 when sewing device 1; Be) time, the pattern data of described selecting/editor's embroidery pattern is sent to described sewing device 1 (S7).After this, flow process turns back to S3.When sewing device 1 can not receive data so that the power supply of sewing device 1 is not opened (S6; In the time of not), flow process is returned S5.

As shown in figure 44, in sewing device 1 controller 13, when power switch 15 is opened, begin control.In initialization (S10) afterwards, sewing device 1 can receive data.Select/(S11 when the edit pattern data send from game machine 6 when described; Be), sewing device 1 receives described pattern data (S12).Then, as described startup/shutdown switch 16 (S13 that is opened; Be), sewing is handled according to the pattern data (S14) of described reception and is carried out.

The beamhouse operation that needed to carry out before sewing operation begins will be described below.

The safety of described sewing device 1 renovate 3 be in shown in Fig. 2 the restoration position state time, the embroidery frame 4 that has a work cloth 70 inserts slit 3f from embroidery frame and inserts described safety and renovate within 3, embroidery frame 4 is by guide element 69 guidings of embroidery frame 4 simultaneously.The coupling part 18a engagement of part 4a and mule carriage 18 is supported at the rear portion of described embroidery frame 4.As mentioned above, embroidery frame 4 mule carriage 18 that can be connected thereto definitely is positioned at swing arm 40 substantially.At this initialization step (S10), mule carriage 18 moves on to this position and standby.Safety head 3 is in restoration position, and embroidery frame 4 protrudes a little from described safety head 3.

After embroidery frame 4 connected to come mule carriage 18, guide element 69 was held, and safety renovates 3 makes it be placed on the sewing position shown in Fig. 3 to front slide.At this state, the sewing box 5 that is holding the line 20 of required color inserts slit 68 from box and inserts within the safety heads 3 and be connected to described swing arm 40.After this preparation process was finished, sewing was handled and can be continued to carry out.

When safety head 3 was in position except that described sewing position, startup/shutdown switch 16 can not be operated, because described startup/shutdown switch 16 is covered with by described safety head 3.When described safety head 3 is switched to described sewing position, described startup/shutdown switch 16 is facing to described switching manipulation 3e, and therefore described startup/shutdown switch 16 can be operated.As described startup/shutdown switch 16 (S13 that is opened; Be), sewing is handled (S14) and is performed.

As shown in figure 42, the pattern data that is stored in each embroidery pattern of described DVD120 comprises the area of the pattern data of several area of the pattern.Described sewing box is changed to the color that each area of the pattern changes line.That is, shown in Figure 44, when startup/shutdown switch 16 is opened (S13; Be) time, sewing is handled (S14) and is performed.According to the pattern data of an area of the pattern, embroidery frame driving mechanism 11 and box driving mechanism 12 are controlled, and area of the pattern is sewed on described work cloth 70.

When an area of the pattern formed, the sewing operation of area of the pattern 5 was finished (S15).When next sewing pattern zone had a kind of different color, sewing box 5 was become other and is accommodated the sewing box 5 that is used for next sewing pattern part color line.In this case, for example, when the change of line is carried out (S16 by the predetermined button of operation control 7; Be) time, line relaxation is handled (S17) and is performed, so that cut off described line and change sewing box 5.

When described sewing box 5 needn't change, handling at the line relaxation of S17 did not need to carry out.That is, when the change of line by order (S16; Not), flow process turns back to S13.Correspondingly, described startup/shutdown switch 16 (S13 that is opened; Be) simultaneously sewing operation be stopped (S15), sewing operation (S14) is begun again.Thereby next pattern part is formed.

Line relaxation is handled and be will be described below.

In the online relaxation processes, after sewing operation was finished, embroidery frame 4 moved to a mobile restriction site from a sewing end position in embroidery frame moving area 38.Then, embroidery frame driving mechanism 11 is controlled to loosen the line 99 between hollow needle 81 and work cloth 70, so that from 82 drag wires of bobbin described in the sewing box 5.Line loosens the ROM13b in the controller 13 that control program is stored in sewing device 1.Line loosens control program and can be stored in other storage mediums, as DVD120, and can be transferred in the sewing device 1.

Figure 45 A illustrate embroidery frame 4 a pattern part by one after just finishing the sewing end position.To 45C, " 0 " expression is positioned at embroidery frame moving area 38 a stitching position of the hollow needle 81 of center substantially at Figure 45 A." X " is illustrated in hollow needle 81 and thrusts a last stitching position in the work cloth 70 at last at an area of the pattern.

Figure 45 B is illustrated in the embroidery frame moving area 38, is moved to the embroidery frame 4 of a mobile limit positions, thereby described hollow needle 81 is by the position that moves to the farthest from described last stitching position of moving of embroidery frame 4.Figure 45 C is illustrated in the moving zone 38 of embroidering frame, with respect to by a frame separation point position shown in the doublet, is moved to the embroidery frame 4 of the mobile limit positions of farthest.

As shown in figure 46, when the LSOR of S17 is handled beginning, determine in step S20 whether the line that is used is decorative pattern zone on being used for.When the line that is used is to be used for last decorative pattern zone (S20; Be), that is to say, that is to say, when all pattern parts of embroidery pattern form, shown in Figure 45 C, the moving limit position of an embroidery frame 4 is calculated (S21), and described moving limit position is the position farthest with respect to the frame separation point position (shown in doublet) of embroidery frame 4.According to the data that calculate, the embroidery frame driving mechanism 11 controlled embroidery frames 4 that make are moved to described moving limit position (S22).

Correspondingly, line 99 is drawn out from the bobbin 82 of sewing box 5.Then, embroidery frame 4 is moved and stops at described embroidery frame separation point position (S23), and the line 99 that is between work cloth 70 and the hollow needle 81 is relaxed.Then, be displayed on CRT8 (S24) separating of the direction of line cutting operation and embroidery frame 4 by game machine 6.When described embroidery frame 44 is moved to described framework apart position, mule carriage 18 just be moved to described foremost position and be positioned at swing arm 40 below.

When the line that is used is not to be used for a last area of the pattern (S20; Not), that is, when all area of the pattern of embroidery pattern did not form, the moving limit position of described embroidery frame 4 is calculated made hollow needle 81 be moved to the position farthest (S25) with respect to a last stitching position.For example, when one of embroidery frame 4 sewing end position is position shown in Figure 45 A, embroidery frame 4 just is moved to a position shown in Figure 45 B according to the data that calculate, and the embroidery frame driving mechanism 11 controlled embroidery frames 4 that make are moved to described moving limit position (S26).

Correspondingly, line 99 is pulled out long enough from the bobbin 82 that is positioned at sewing box 5.Then, embroidery frame 4 turns back to described sewing end position, and (S27) carried out in the motion of embroidery frame 4 on the contrary thus.The line 99 that is between work cloth 70 and the hollow needle 81 is relaxed.Then, embroidery frame 4 forbids that the direction of the warning that separates and line cutting operation is presented at described CRT8 by game machine 6 and goes up (S28).

Work as S22, S23 when S26 and S27 are performed, as mentioned above, is in line 99 line relaxations between hollow needle 81 and the work cloth 70.According to the direction of the line cutting operation that is presented at described CRT8 in S24 and S28, line 99 is cut.Till that time, when the embroidery frame moving area 38 of embroidery frame 4 had described safety head 3 to cover, line 99 can easily manually cut and needn't remove safety head 3 from sewing device main body 2.For example, scissors inserts the inside that seam 3f inserts safety head 3 from embroidery frame.Simultaneously, the inside of safety head 3 is from the visual observation of the safety head 3 made by transparent or trnaslucent materials, and line 99 can easily be used described scissors cut.

Then, when the sewing operation of embroidery pattern is done, that is, and when S21 when S24 has executed, the embroidery frame 4 that is positioned at the embroidery frame separation point position can easily separate from sewing device main body 2 according to the embroidery frame detaching direction that is presented on the described CRT8.When embroidery frame 4 was in described embroidery frame separation point position, described mule carriage 18 was positioned at below the swing arm 40 substantially, and in described embroidery frame separation point position, embroidery frame 4 is moved to the foremost position place in the embroidery frame moving area 38.When the work cloth 70 that is formed with embroidery pattern on it after embroidery frame 4 is removed, as shown in figure 37, double-faced adhesive tape 77 is connected to the reverse side of work cloth 70, therefore a pattern cloth 78 is formed.Pattern fabric 78 can connect various things by double-faced adhesive tape 77.

When the sewing of embroidery pattern is not also finished, that is, after S25 executed to the step of S28, and online cutting is intact, sewing box 5 was changed into other sewing box 5 that accommodates the line of next area of the pattern use.After this, when startup/shutdown switch 16 is opened at S13, carried out again in the processing of S14 and processing afterwards.After sewing operation was done, safety head 3 was moved to described restoration position.Then, embroidery frame 4 can be removed from embroidery frame insertion seam 3f.
