達42可由例如步進馬達所構成，而馬達之動力依照可變 15 軸％、偏心凸輪38、移動連桿36之順序傳達，並可使移動 連桿36移動引導構件34。 斜齒輪41與斜齒輪43相咬合，使馬達42之驅動可輸出 至與可變轴39之轴方向垂直之方向防。斜齒輪做後端同 5軸上連結有轴承44、内壓腳升降凸輪辦。即因馬達42 也可作為内壓腳升降凸輪45之驅動源，故内壓腳Μ之升降 係藉由馬達42所傳來之驅動力而進行。 如第5圖〜第7圖所示，内壓腳升降凸輪45以通過旋動 中心為界，一方面，旋動中心至外周面之距離形成大致相 10同之圓弧狀（以下稱為維持部45a);另一方面，旋動中心至 外周面之距離較維持部45a之旋動中心至外周部之距離 大，且為平滑變化之形狀（以下稱為變化部45b)。又如第3 圖及第5圖〜第7圖所示，内壓腳升降凸輪45之一面側上形 成有固定部45c，其係可將内壓腳升降凸輪45固定於可傳達 15馬達42所傳達之驅動力之驅動軸51者。此外，該固定部45c 上形成有向變化部45b之外周緣延伸之突起部45c。 内壓腳升降凸輪45可升降内壓腳上升構件46，其係可 使内壓腳2 9上升至縫製結束後之退避高度位置p 5 (後述) 者’而内壓腳升降凸輪45之外周面抵接於設置於内壓腳上 20升構件46之一端部之圓筒狀滾輪47外周面。即，當内壓腳 升降凸輪45之維持部45a與滾輪47抵接時’内壓腳上升構件 46不會上升(參照第7圖）；但是當内壓腳升降凸輪45之變化 部45b與滾輪47抵接時，内壓腳上升構件46便會上升（參照 第5圖）。即’内壓腳升降凸輪45、内壓腳上升構件46及滾 16 1373538 輪47構成升降驅動機構M2。 内愿腳上升構件46在其中腹部藉由銷48可自由旋動地 安裝於縫幼機外框15上。且内虔腳上升構件处之他端部設

1373538 又，於内壓腳升降凸輪45之上方設置有遮蔽板55，其 係可進出藉由電磁線圈54所保持之内壓腳上升回復腕52之 前端部與突出部45d之間，且構成可防止内壓腳上升回復腕 52接觸突出部45d之移動限制機構M4者。即，為了維持内 5壓腳29的位置而不欲使内壓腳升降凸輪45旋轉時，可將遮 蔽板55移動至内壓腳上升回復腕52之前端部與突出部45d 之間。 在此說明内壓腳29與外壓腳1〇4之位置關係。 如第8圖所示，將内壓腳29在縫製時待機之位置稱為内 10壓腳下位置P4，内壓腳29於縫製結束後退避至上方之位置 稱為内壓腳退避位置P5。又，將外壓腳1〇4在縫製時壓住縫 製物之位置稱為外壓腳下位置，而外壓腳1〇4於縫製結束後 退避後之位置稱為外壓腳上位置。 該等位置關係相對針板101之高度由高排到低為：内壓 15腳退避位置P5、外壓腳上位置、内壓腳下位置P4、外壓腳 下位置。 <縫製時内壓腳之動作> 接著，說明具有上述構成之内壓腳裝置]^之動作。 驅動上軸馬達（省略圖示）使偏心凸輪3旋動時，接續連 20接環4的前端向略垂直於上軸2之軸線的方向（橫越第3連桿 20與第4連桿22之直列方向D2之方向D3)搖動，連結於接續 連接環4之搖動軸聯結器5也向同方向搖動。藉由搖動軸聯 結器5之搖動，搖動輛6也跟著搖動，故以第丨連桿8之—端 部作為搖動支點，第1連桿8之另一端部向略垂直於搖動軸6 18 泉之方向（橫越第3連桿20與第4連桿22之直列方向D2之 1向D3)搖動。隨著第j連桿8之另一端部的搖動，第2連桿 之另一端部向第3連桿2〇與第4連桿22之直列方向D2搖 =連結於第2連桿11另一端部之第3連桿2〇及第4連桿22向 、直列方向（上下方向）D2搖動。隨著第3連桿2〇及第4連桿 之搖動’連結第4連桿22之内壓桿28沿上下方向D1向下方 移動，故内壓腳29也向上下方向移動。 <内壓腳裝置之内壓腳下位置之調節動作> 接著，說明具有上述構成之内壓腳裝置丨中之内壓腳下 位置P4之調節動作。 驅動馬達42時，則馬達42之驅動透過斜齒輪41 、軸承 〇傳達至可動軸39，使可動軸39開始旋動。藉由可動轴39 之旋動，偏心凸輪38也開始旋動，移動連桿36向略垂直於 可動轴39轴線之方向（橫越第3連桿2〇與第4連桿22之直列 方向D2之方向〇3)搖動。藉由移動連桿36之搖動，引導構件 34向橫越第3連桿20與第4連桿22之直列方向D2之方向d3 搖動。 此時，如第9圖所示，以引導構件34之長孔34a連結第3 連桿20與第4連桿22之連結部P3之有肩螺釘幻，由於其螺紋 部分被長孔34a限制住往橫越第3連桿2〇與第4連桿22之直 列方向D2之方向D3之移動，故由搖動所傳來之力無處可 洩；有肩螺釘23沿著長孔34a往上方移動，隨著有肩螺釘23 跟著引導構件34之移動，排成直列互相連結之第3連接部2〇 與第4連接部22兩者之角度θ發生變化；内壓腳連接構件24 1373538 變成略呈〈字形。内壓腳連接構件24變成略呈〈字形時， 内壓腳連接構件24之兩端部間的距離l，換言之，即第3連 接部20之一端部與第4連接部22之另一端部間之距離L會變 短，内壓腳29會沿著上下方向D1移動至上方。藉此可調節 5 内壓腳29之内壓腳下位置P4。 <内壓腳裝置之内壓腳之退避動作> 接著，說明縫製結束後内壓腳29移動至内壓腳退避位 置P5時之動作。 内壓腳高度位置P4之調節係藉由調節各連桿比並使馬 10達42在〇〜180之範圍内旋動而進行；内壓腳29之退避係 藉由使馬達42在180。〜360。之範圍内旋動而進行。 即，調節内壓腳下位置P4時，馬達42在〇。〜18〇。之範 圍内旋動，則内壓腳升降凸輪45之維持部45a會抵接滾輪 47;内壓腳29退避時，馬達42在180。〜360。之範圍内旋動， 15則内壓腳升降凸輪45之變化部45b會抵接滾輪47而連結各 部。 因此，如第5圖〜第7圖所示’由於馬達42在〇。〜18〇。 之範圍内旋動，故維持部45a抵接於滾輪47而内壓腳上升連 桿46不會旋動。因此，内壓腳上升連桿46不會將内壓桿聯 20結器27推至上方，可僅調節内壓腳高度位置P4。然而，縫 製結束後馬達42在180。〜360。之範圍内旋動，則變化部45b 抵接至滾輪47而將内壓腳上升連桿46之一端部壓至下方。 然後，内壓腳上升連桿46以銷48為支點旋動，内壓腳上升 連桿46之另一端部移動至上方，將設置於移動路程上之内 20 壓才干聯結器27推至上方。藉此，内壓腳四可上升至内壓腳 退避位置P5。 <縫初機之電源斷電時内壓腳之升降動作> 接著，說明縫製結束後使内壓腳四升降時之動作。 5 在縫紉機100之電源斷電時内壓腳29位於内壓腳退避 位置之情況下，縫切機100之電源若遭靖，則電磁線圈54 之電源也會被切斷。由於電磁線圈54之電源被切斷時，内 壓聊上升回復腕52會脫離被保持狀態，故内壓腳上升回復 腕52會因螺旋彈簧53所賦予之勢能向前方彈出而推向突出 1〇部4元。而，'藉由内壓腳上升回復腕52抵接突出部45d，内 壓腳上升回復腕52之運動能量傳達至突出部45d，而突出部 45d開始向第5圖之順時針旋轉。 在此，在内壓腳29位於内壓腳退避位置p5之情況下， 内屋腳升降凸輪45之變化部45b抵接滾輪47，由於從内塵腳 15升降凸輪45之旋轉中心至維持部45a之距離與至變化部价 之距離不同，故如第9圖所示，與滾輪47之抵接處由變化部 45b移到維持部453時，與滚輪47之抵接位置會漸漸產生變 化。藉此，突出部45d開始旋轉時，其後即使不施予旋轉力， 内壓腳升降凸輪45也會慢慢地旋轉。然後，如同上述，由 於藉由内壓腳升降凸輪45之旋轉，與滾輪47之抵接位置會 從文化部45b變成維持部45a，故内壓腳上升連桿46會開始 向第6圖之逆時針;5疋轉，而内壓腳29會向内壓腳下位置 下降。本機構係可使前述升降驅動機構動作而使前述内壓 腳向前述内壓腳下位置㈣之移動控制機構。 21 一方面，縫紉機100之電源斷電後欲將内壓腳29維持在 内壓腳退避位置P5時，則將遮蔽板55移動至突出部45d及内 壓腳上升回復腕52之間。藉此，由於電磁線圈54之電源斷 電，即使内壓腳上升回復腕52彈向突出部45d，内壓腳上升 5回復腕52也會撞到遮蔽板55而被限制住往突出部45d之移 動’故内壓腳升降凸輪45不會旋轉，而可將内壓腳29維持 於内壓腳退避位置P5。本機構係可限制前述移動控制機構 對前述升降驅動機構之㈣動作之㈣限制機構。 <第1實施型態之作用效果> 1〇 根據第1實施型態中之_機之内壓腳裝置卜於縫匆 機励之電源斷電時’在可退避至預定位置之外壓腳退避至 前述預定位置之情況下，藉由内壓腳上升回復腕52抵接内 壓腳升降凸輪45之突出部45d而使内壓腳升降凸輪衫旋 轉，可使内壓腳29移動至内壓腳下位置P4，則内壓腳29不 U會妨礙針桿下降而使針桿無法下降，也不會使線無法穿過 車針術。又，^於縫關1⑻之電_電時遮蔽板55限

内壓腳升降凸輪45之變化部45b抵接滾輪47,由於從内壓腳 升降凸輪45之旋轉中心至維持部45a之距離與至變化部45 之距離不同，故如第9圖所示，於與滾輪47之抵接處由變化 部45b變成維持部45a時，與滚輪47之抵接位置慢慢地變 10化。藉此，内壓腳升降凸輪445開始旋轉，其後即使不施予 方疋轉力，内壓腳升降凸輪45也會慢慢地旋轉。然後，如上 所述，由於藉由内壓腳升降凸輪45之旋轉，與滾輪47之抵 接位置可由變化部45b移動至維持部45a，故内壓腳上升連 桿46會開始向第5圖〜第7圖之逆時針方向旋轉，而内壓腳 15 29會向内壓腳下位置p4下降。 另一方面，欲將内壓腳29設定於内壓腳退避位置p5之 情況下，藉由控制裝置90不送出驅動馬達42之訊號，馬達 42會保持停止狀態，内壓腳升降凸輪牦也不會旋轉，可使 内壓腳29維持在内壓腳退避位置p5。 2〇 即，第施型態係一種縫切機之内壓腳裝置，具有可 使前述内壓腳沿車針之上下移動方向升降之升降驅動機 構、及可使前述升降驅動機構動作之驅動機構，且更包括： 記憶機構，係可記憶對應記錄前述内壓腳退避位置及前述 内壓腳下位置與前述驅動機構之驅動量之内壓腳位置資料 24 1373538 者；驅動控制機構’係於前述縫紉機之電源斷電時，可根

That is, when the holding portion 45a of the inner presser foot lifting cam 45 abuts against the roller 47, the inner presser foot raising member 46 does not rise (refer to Fig. 7); however, when the inner presser foot lift cam 45 changes the portion 45b and the roller When the 47 is abutted, the inner presser foot raising member 46 rises (refer to Fig. 5). That is, the inner presser lift cam 45, the inner presser riser 46, and the roller 16 1373538 wheel 47 constitute the lift drive mechanism M2. The inner leg raising member 46 is rotatably attached to the slit machine outer frame 15 by a pin 48 in the abdomen. And the other end portion of the inner leg raising member is disposed at a position below the inner dust leg coupling 27, and the deforming portion 45b of the inner presser foot lifting cam 45 abuts against the roller 47 (4) the other end portion of the presser foot rising member Ascending, the inner presser foot coupler 27 is raised, and the inner presser foot 4 is raised to the original high position P5 (see Fig. 5).

Thereby, the end of one of the inner presser members 46 can be always pulled upward. 15 (4) in the fixed portion & ± protrusion formed in the inner presser foot lifting cam 45 (4), in the direction of the vertical drive axis, a (four) foot μ return wrist 52 is provided, which can be used when the power supply of the rib machine is powered off. The inner presser foot lifting cam 45 is rotated to move the inner presser foot 29 to the inner presser foot position p4@. The inner presser foot is raised to return to the wrist 52-rod member, and the rear end portion thereof is attached to the sewing machine outer punch 15 through a coil spring 53 as an elastic member. The internal presser foot rises and rests the wrist 52 by the power supply of the sewing machine 100 at the same time as the power supply of the machine 100 is simultaneously turned off, and the electromagnetic coil 54 which is simultaneously stopped at the same time acts on the potential energy imparted by the sewing spring 53. , — Keep the screw on the sewing machine~ When the power of the sewing machine is turned off, the internal presser foot rises and the wrist 52 will be disengaged from the held position. The return of the wrist 52 will be pushed by the coil spring 53. Projection portion 45d. That is, the inner presser foot rises and the wrist & spring 53 and the electromagnetic coil 54 constitute the movement control mechanism M3. The red bomb 17 1373538 is further provided with a shielding plate 55 above the inner presser foot lifting cam 45, which can be moved in and out. The inner presser foot held by the electromagnetic coil 54 rises and rests between the front end portion of the wrist 52 and the protruding portion 45d. Further, it constitutes a movement restricting mechanism M4 that can prevent the inner presser from rising and returning the wrist 52 to the protruding portion 45d. That is, in order to maintain the position of the inner presser foot 29 without rotating the inner presser foot lift cam 45, the shutter 55 can be moved between the front end portion of the inner presser foot returning arm 52 and the projecting portion 45d. Here, the positional relationship between the inner presser foot 29 and the outer presser foot 1〇4 will be described. As shown in Fig. 8, the position at which the inner presser 29 is in standby at the time of sewing is referred to as the inner 10 presser foot position P4, and the position at which the inner presser 29 is retracted to the upper side after the sewing is completed is referred to as the inner presser foot retracted position P5. Further, the position at which the outer pressing leg 1〇4 is pressed against the sewing material at the time of sewing is referred to as the outer pressing foot position, and the position at which the outer pressing leg 1〇4 is retracted after the sewing is completed is referred to as the position on the outer pressing foot. The positional relationship with respect to the height of the needle plate 101 from high to low is: internal pressure 15 foot retraction position P5, external pressure foot position, internal pressure foot position P4, external pressure foot position. <Operation of the inner presser during sewing> Next, the operation of the inner presser device having the above configuration will be described. When the upper shaft motor (not shown) is driven to rotate the eccentric cam 3, the distal end of the continuous 20-ring 4 is directed in a direction slightly perpendicular to the axis of the upper shaft 2 (crossing the third link 20 and the fourth link 22) In the direction D3 of the in-line direction D2, the rocking shaft coupling 5 connected to the connecting ring 4 is also rocked in the same direction. By shaking the shaft coupling 5, the rocking device 6 is also rocked, so that the end of the third link 8 is used as the rocking fulcrum, and the other end of the first link 8 is slightly perpendicular to the rocking shaft 6 18 spring. The direction (1 to D3 across the in-line direction D2 of the third link 20 and the fourth link 22) is swung. As the other end of the j-th link 8 is rocked, the other end of the second link is rocked in the in-line direction D2 of the third link 2〇 and the fourth link 22 to be coupled to the other end of the second link 11 The third link 2〇 and the fourth link 22 of the portion are oscillated in the in-line direction (up-and-down direction) D2. As the third link 2〇 and the fourth link are rocked, the inner pressing rod 28 that connects the fourth link 22 moves downward in the vertical direction D1, so that the inner presser 29 moves in the vertical direction. <Adjustment operation of the inner presser foot position of the inner presser device> Next, the adjustment operation of the inner presser foot position P4 in the inner presser device 丨 having the above configuration will be described. When the motor 42 is driven, the drive of the motor 42 is transmitted to the movable shaft 39 through the helical gear 41 and the bearing ,, and the movable shaft 39 starts to rotate. By the rotation of the movable shaft 39, the eccentric cam 38 also starts to rotate, and the moving link 36 is directed in a direction slightly perpendicular to the axis of the movable shaft 39 (crossing the in-line direction of the third link 2〇 and the fourth link 22) Direction of D2 〇 3) Shake. By the rocking of the moving link 36, the guiding member 34 is swung in a direction d3 which traverses the in-line direction D2 of the third link 20 and the fourth link 22. At this time, as shown in Fig. 9, the shoulder screw of the joint portion P3 of the third link 20 and the fourth link 22 is coupled by the long hole 34a of the guide member 34, and the threaded portion is restricted by the long hole 34a. The movement of the third link 2〇 and the fourth link 22 in the direction D3 of the in-line direction D2 is traversed, so that the force transmitted by the shaking is nowhere to be vented; the shoulder screw 23 moves upward along the long hole 34a. With the movement of the shoulder screw 23 following the guiding member 34, the angle θ between the third connecting portion 2〇 and the fourth connecting portion 22 which are arranged in line with each other changes; the inner presser connecting member 24 1373538 becomes slightly <glyph. When the inner presser foot connecting member 24 is slightly "shaped", the distance l between the both end portions of the inner presser foot connecting member 24, in other words, between the one end portion of the third connecting portion 20 and the other end portion of the fourth connecting portion 22 The distance L is shortened, and the inner presser foot 29 is moved upward in the up and down direction D1. Thereby, the inner presser foot position P4 of the inner presser foot 29 can be adjusted. <Retraction operation of the inner presser foot of the inner presser device> Next, the operation when the inner presser foot 29 is moved to the inner presser foot retracted position P5 after the sewing is completed will be described. The adjustment of the inner presser foot height position P4 is performed by adjusting the respective link ratios and rotating the horse 10 to 42 in the range of 〇 to 180; the retraction of the inner presser foot 29 is performed by setting the motor 42 at 180. ~360. Rotate within the range. That is, when the inner pressure foot position P4 is adjusted, the motor 42 is in the cymbal. ~18〇. When the inner circumference is rotated, the holding portion 45a of the inner presser foot lifting cam 45 abuts against the roller 47; when the inner presser 29 is retracted, the motor 42 is at 180. ~360. In the range of rotation, the change portion 45b of the inner presser foot lifting cam 45 abuts against the roller 47 to connect the respective portions. Therefore, as shown in Figs. 5 to 7, the motor 42 is in the crucible. ~18〇. Since the rotation is in the range, the holding portion 45a abuts against the roller 47 and the inner presser foot rising link 46 does not rotate. Therefore, the inner presser foot rising link 46 does not push the inner press bar linker 27 upward, and only the inner presser foot height position P4 can be adjusted. However, the motor 42 is at 180 after the sewing is completed. ~360. When the rotation is within the range, the changing portion 45b abuts against the roller 47 and presses one end portion of the inner presser foot rising link 46 downward. Then, the inner presser foot raising link 46 is pivoted with the pin 48 as a fulcrum, and the other end of the inner presser foot rising link 46 is moved upward, and the inner pressure coupling connector 27 is pushed upward. Thereby, the inner presser foot 4 can be raised to the inner presser foot retracting position P5. <Lifting and lowering operation of the inner presser foot when the power supply of the sewing machine is turned off> Next, the operation of raising and lowering the inner presser foot 4 after the sewing is completed will be described. 5 When the inner presser 29 is in the inner presser retracted position when the power of the sewing machine 100 is turned off, if the power of the slitter 100 is stabilized, the power of the electromagnetic coil 54 is also cut off. When the power supply of the electromagnetic coil 54 is cut off, the internal pressure rises and the return wrist 52 is released from the held state. Therefore, the internal presser foot rises and the wrist 52 is pushed forward by the potential energy given by the coil spring 53 to push forward. Department 4 yuan. On the other hand, the movement energy of the inner presser foot returning to the wrist 52 is transmitted to the projecting portion 45d, and the projecting portion 45d starts to rotate clockwise in Fig. 5 by the inner presser foot returning arm 52 abutting against the projecting portion 45d. Here, when the inner presser foot 29 is located at the inner presser foot retracting position p5, the changing portion 45b of the inner leg lift cam 45 abuts against the roller 47, and the center of rotation of the cam 45 is lifted from the inner dust leg 15 to the maintaining portion 45a. Since the distance is different from the distance to the change price, as shown in Fig. 9, when the contact portion with the roller 47 is moved to the holding portion 453 by the changing portion 45b, the contact position with the roller 47 gradually changes. Thereby, when the protruding portion 45d starts to rotate, the inner presser foot lifting cam 45 is slowly rotated even if the rotational force is not applied thereafter. Then, as described above, since the contact position with the roller 47 is changed from the cultural portion 45b to the maintaining portion 45a by the rotation of the inner presser foot lifting cam 45, the inner presser foot rising link 46 starts to reverse the sixth figure. The hour hand; 5 turns, and the inner presser foot 29 will fall toward the inner presser foot position. This mechanism is a movement control mechanism that can operate the lift drive mechanism to move the inner presser to the inner presser foot position (4). On the other hand, when the internal presser foot 29 is to be maintained at the inner presser foot retracted position P5 after the power of the sewing machine 100 is turned off, the shield plate 55 is moved between the projecting portion 45d and the inner presser foot returning arm 52. Thereby, since the power supply of the electromagnetic coil 54 is de-energized, even if the inner presser foot rises and the return wrist 52 bounces toward the protruding portion 45d, the inner presser foot rises 5 and the return wrist 52 hits the shield plate 55 and is restricted to the projecting portion 45d. The movement "the inner presser foot lifting cam 45 does not rotate, and the inner presser foot 29 can be maintained at the inner presser foot retracting position P5. The mechanism can limit the (four) restriction mechanism of the (four) action of the aforementioned movement control mechanism to the aforementioned movement control mechanism. <Effects and Effects of the First Embodiment> 1) According to the first embodiment, the internal presser device of the machine is in a state where the power is turned off when the power is turned off. When the foot is retracted to the predetermined position, the inner presser foot returning arm 52 abuts against the protruding portion 45d of the inner presser foot lift cam 45, and the inner presser foot lift cam plate rotates, so that the inner presser foot 29 can be moved inside. When the presser foot is in the position P4, the internal presser foot 29 is not U, which will prevent the needle bar from falling, so that the needle bar cannot be lowered, and the wire cannot pass through the bur. Moreover, the electric shielding plate 55 of the slit 1 (8) restricts the internal pressure foot 29 from being rotated in the inner pressing foot retracting position due to the inner pressing of the lifting cam 52 caused by the inner leg rising and returning to the wrist 52. If the tire is pressed, the inner presser foot 29 will not interfere with the installation, and will not touch the pressure frame when it is lowered, and the pressure frame 1〇5 will be damaged. Therefore, it is possible to improve the workability of the power supply after the power is cut off. [Second Embodiment] <Configuration of Inner Presser Device> As shown in Fig. 2 and Fig. 1 and Fig. U, in the second embodiment, 22 1373538 presser device 1G is configured to be controlled. The device 9A controls the lifter of the inner presser foot 29 instead of the movement control mechanism and the movement restricting mechanism in the i-th embodiment. The components other than the control device 90 are the same as those in the first embodiment, and the same reference numerals will be given thereto, and the description thereof will be omitted. As shown in Fig. 11, the control unit 9 has a CPU 91 for performing various processes, a memory % as a memory system memory program, or a material. The memory 92 is processed by the CPU 91, and the data for processing is recorded. The data area 94 is formed by a program area 95 in which the internal delay device performs various operations. 1〇(4) Area 94 The memory has a corresponding recording field foot retraction device p5 and an internal pressure foot position P4 and a motor 42 The internal pressure foot position data of the driving amount is corrected. Specifically, the σ inner pressure foot position data 9 is stored as follows: the rotation angle of the motor 42 required to move the inner pressing foot 29 to the inner pressing foot retracting position, and the internal pressure The foot 29 is moved to the angle of the reel shaft required for the position of the inner presser foot. 15 The 95 area 95 has a drive (4) program 95a, which is based on the position of the presser foot in the data area 94. That is, the control device 90 generates the function of the drive control mechanism by executing the drive control program by the CPU 91. <The lifting operation of the internal presser foot when the power supply of the sewing machine is powered off is turned off. Control of the control device 90 when the foot 29 is raised and lowered. When the foot 29 is set at the internal pressure foot position p4, and the control device 9 detects that the power supply of the sewing machine 1 is turned off, the control device 90 utilizes The electric power of the built-in electric power holding device (for example, a capacitor) causes the rotating shaft of the motor 42 to rotate only 23 1373538 according to the amount of the internal waste position information 94a. The driving force of the motor 42 is transmitted to the inner pressing foot lifting cam through the helical gears 41, 43. 45. The inner presser foot lifting cam 45 can turn clockwise in the fifth to seventh figures and rotate only the angle set by the inner presser foot position data 94a. 5 Here, the inner presser foot 29 is located at the inner dust foot retracting position. In the case of p5, the changing portion 45b of the inner presser foot lifting cam 45 abuts against the roller 47, and the distance from the center of rotation of the inner presser foot lifting cam 45 to the maintaining portion 45a is different from the distance from the changing portion 45. As shown in the figure, when the changing portion 45b is changed to the maintaining portion 45a at the contact portion with the roller 47, the contact position with the roller 47 is gradually reduced. Thereby, the inner presser foot lifting cam 445 starts to rotate, and thereafter, Even if the rotation force is not applied, the inner presser foot lifting cam 45 is also Then, as described above, since the abutment position with the roller 47 is moved to the maintaining portion 45a by the changing portion 45b by the rotation of the inner presser lift cam 45, the inner presser rising link 46 starts. When the inner presser foot 29 is set to the inner presser foot retracted position p5, the inner presser foot 15 is lowered in the counterclockwise direction from the fifth to seventh figures. When the control device 90 does not send the signal of the drive motor 42, the motor 42 is kept in the stopped state, and the inner presser lift cam 不会 does not rotate, so that the inner presser foot 29 can be maintained at the inner presser foot retracted position p5. 2, that is, the first embodiment is an internal presser device of a slitting machine, and has a lifting drive mechanism for lifting and lowering the inner presser foot in the upward movement direction of the needle, and a driving mechanism capable of operating the lifting drive mechanism And further comprising: a memory mechanism capable of memorizing and recording the inner presser foot retracting position and the inner presser foot position and the driving force of the driving mechanism; wherein the driving control mechanism is attached to the sewing machine When the power source is powered off, the driver may be controlled according to the position of the inner presser foot stored in the memory mechanism. <Operation and Effect of Second Embodiment> 5 According to the internal presser device 1G of the sewing machine in the second embodiment, the CPU 91 of the tanning device 90 executes the drive control program 95a. The motor 42 can be based on the internal presser foot. The position data 94a operates the inner presser lift cam 45. When the control device 90 outputs the driving amount corresponding to the internal presser foot retracting position P5 to rotate the rotating shaft of the motor 42, the inner presser foot 29 can be moved to the inner presser foot retracting position 卩5, and the inner 10 presser foot 29 does not It hinders the installation and does not contact the pressure shaft 1〇5 (see Fig. 1) when it is lowered, and the pressure frame 105 is damaged. Further, when the control device 9 rotates the rotation amount corresponding to the internal pressure foot position P4 to rotate the rotation shaft of the motor 42, the inner presser foot 29 can be moved to the inner presser foot position P4, and the inner presser foot 29 does not interfere with the needle bar. The drop does not allow the needle bar to fall, nor does it allow the wire to pass through the needle. 15 Therefore, the workability of the power supply after the power supply of the seven-lift machine can be turned off. Further, the present invention is not limited to the above embodiment. For example, after the power of the sewing machine 100 is turned off, the internal presser foot 29 does not have to be built in the seam cutting machine. The inner presser foot 29 can be moved to the inner presser foot retracting position ^ and the inner presser foot. In the position P4, the presser foot driving member is moved from the outside of the sewing machine, and the internal presser foot 29 is moved by the manual operation of the operator. Thereby, the inner presser foot 29 can be moved to the inner press backing position p5 and the inner presser foot position P4 by manually manipulating the snapping member from the slitting machine_external. Here, when the inner presser foot 29 is moved to the inner presser foot retracting position p5 by operating the inner presser foot driving member, the inner presser foot 29 does not interfere with the mounting, and does not come into contact with the 25 press frame 1 when it is lowered. 5, the pressure frame 1〇5 is damaged. Further, by operating the inner presser foot driving member, the inner presser foot 29 is moved to the inner presser foot position. At 4 o'clock, the inner presser foot 29 does not prevent the needle bar from falling, so that the needle bar cannot be lowered, and the wire cannot pass through the bur 107. Therefore, the work of the sewing machine 100 after the power is turned off can be improved. Further, the number of links, the connection position, and the connection order of the inner presser foot rocking mechanism M1 may be arbitrary, and the mechanism may be freely changed as long as the wheel 12 can be rotated to move the inner presser foot 29 up and down direction D1. In the embodiment, in order to obtain the desired inner presser foot position p4, 10, the necessary information must be memorized in the control device 90, but the operator can also set the driving amount of the motor 42 each time sewing. The inner presser foot lift cam 45 and the inner presser foot lifter 46 are not provided, and the inner presser foot 29 to the inner presser foot retraction position P5 can be moved by eccentrically turning the output shaft of the motor 42. 15 [Simple description of the drawing] Fig. 2 is a side view of the inner presser device.
