　なお、第１洗濯部１００、及び第２洗濯部２００の各々は、洗濯物を洗い運転、すすぎ運転、脱水運転、及び乾燥運転を行うことが可能である。 Note that each of the first washing unit 100 and the second washing unit 200 can perform a washing operation, a rinsing operation, a dehydrating operation, and a drying operation for the laundry.
　次に、図４を参照して、第１洗濯槽１１０、及び第２洗濯槽２１０について説明する。図４は、洗濯機１の模式図である。 Next, the first washing tub 110 and the second washing tub 210 will be described with reference to FIG. FIG. 4 is a schematic diagram of the washing machine 1.
　図４は、第１傾斜角度θ１と、第２傾斜角度θ２とを示す。第１傾斜角度θ１は、水平方向Ａに対する第１回転軸１１４の傾斜角度を示す。第２傾斜角度θ２は、水平方向Ａに対する第２回転軸２１４の傾斜角度を示す。水平方向Ａは、水平面に平行であり、前方に向かう方向を示す。 FIG. 4 shows the first tilt angle θ1 and the second tilt angle θ2. The first tilt angle θ1 indicates the tilt angle of the first rotating shaft 114 with respect to the horizontal direction A. The second tilt angle θ2 indicates the tilt angle of the second rotation shaft 214 with respect to the horizontal direction A. The horizontal direction A is parallel to the horizontal plane and indicates a direction toward the front.
　なお、図４において、水平方向Ａを示す矢印の先端が基端を中心に時計回りに回転する方向を正の方向（図４において「＋」）とする。また、図４において、水平方向Ａを示す矢印の先端が基端を中心に反時計回りに回転する方向を負の方向（図４において「－」）とする。 In FIG. 4, the direction in which the tip of the arrow indicating the horizontal direction A rotates clockwise around the base end is defined as a positive direction (“+” in FIG. 4). In FIG. 4, the direction in which the tip of the arrow indicating the horizontal direction A rotates counterclockwise about the base end is defined as a negative direction (“−” in FIG. 4).
　第１回転軸１１４、及び第２回転軸２１４の各々が水平方向Ａに対して正の方向に傾斜している場合、第１傾斜角度θ１、及び第２傾斜角度θ２の各々は、角度０°よりも大きくなる。 When each of the first rotation shaft 114 and the second rotation shaft 214 is inclined in the positive direction with respect to the horizontal direction A, each of the first inclination angle θ1 and the second inclination angle θ2 has an angle of 0 °. Bigger than.
　これに対し、第１回転軸１１４、及び第２回転軸２１４の各々が水平方向Ａに対して負の方向に傾斜している場合、第１傾斜角度θ１、及び第２傾斜角度θ２の各々は、角度０°よりも小さくなる。 On the other hand, when each of the first rotation shaft 114 and the second rotation shaft 214 is inclined in the negative direction with respect to the horizontal direction A, each of the first inclination angle θ1 and the second inclination angle θ2 is The angle is smaller than 0 °.
　図４に示すように、第１傾斜角度θ１が、第２傾斜角度θ２よりも大きい（第１傾斜角度θ１＞第２傾斜角度θ２）。従って、第２洗濯槽２１０の後部２１５を、第１洗濯槽１１０の後部１１５から離間させて配置することが可能になる。その結果、第１洗濯槽１１０の後部１１５と前記第２洗濯槽２１０の後部２１５との間に第２排水経路部２４０を配置するための第２空間Ｂ２を確保することが可能になる。 As shown in FIG. 4, the first inclination angle θ1 is larger than the second inclination angle θ2 (first inclination angle θ1> second inclination angle θ2). Accordingly, the rear portion 215 of the second washing tub 210 can be disposed apart from the rear portion 115 of the first washing tub 110. As a result, it is possible to secure a second space B2 for arranging the second drainage path portion 240 between the rear portion 115 of the first washing tub 110 and the rear portion 215 of the second washing tub 210.
　また、第１実施形態では、第２空間Ｂ２を確保するために、第１洗濯槽１１０から第２洗濯槽２１０全体を離間させずに、第１洗濯槽１１０から第２洗濯槽２１０の後部２１５のみを離間させる。言い換えれば、第１実施形態では、第２空間Ｂ２を確保するために、第１回転軸１１４と第２回転軸２１４とが互いに平行な状態から、第１回転軸１１４に対して第２回転軸２１４を上方に平行移動せずに、第１回転軸１１４に対する第２回転軸２１４の傾斜角度を変更する。従って、第２回転軸２１４を上方に平行移動する場合に比べて、筐体１０の上下方向の寸法Ｈが増加することを抑制できる。その結果、洗濯機１の筐体１０をコンパクトにすることが可能になる。 Moreover, in 1st Embodiment, in order to ensure 2nd space B2, the rear part 215 of the 2nd washing tub 210 from the 1st washing tub 110 without separating the 2nd washing tub 210 whole from the 1st washing tub 110. Separate only. In other words, in the first embodiment, in order to secure the second space B <b> 2, the first rotation shaft 114 and the second rotation shaft 214 are parallel to each other, so that the second rotation shaft 114 and the second rotation shaft 114 are parallel to each other. The tilt angle of the second rotating shaft 214 with respect to the first rotating shaft 114 is changed without translating 214 upward. Therefore, it is possible to suppress an increase in the dimension H in the vertical direction of the housing 10 as compared to the case where the second rotation shaft 214 is translated upward. As a result, the casing 10 of the washing machine 1 can be made compact.
　続いて、図４を参照して、第１洗濯槽１１０について説明する。 Subsequently, the first washing tub 110 will be described with reference to FIG.
　図４に示すように、第１傾斜角度θ１は、角度０°よりも大きい（第１傾斜角度θ１＞角度０°）。第１実施形態では、第１傾斜角度θ１は、例えば、角度略８°である。従って、第１洗濯槽１１０の第１開口部１１３が水平方向Ａよりも上向きに配置される。その結果、ユーザーが、第１洗濯槽１１０に対して洗濯物を出し入れする第１作業を容易に行うことができる。理由は、ユーザーは、通常、第１洗濯槽１１０を見下ろすようにして第１作業を行うからである。 As shown in FIG. 4, the first inclination angle θ1 is larger than the angle 0 ° (first inclination angle θ1> angle 0 °). In the first embodiment, the first inclination angle θ1 is, for example, an angle of approximately 8 °. Accordingly, the first opening 113 of the first washing tub 110 is disposed upward from the horizontal direction A. As a result, the user can easily perform the first work of putting the laundry in and out of the first washing tub 110. The reason is that the user normally performs the first work while looking down at the first washing tub 110.
　また、第１傾斜角度θ１は、角度０°よりも大きいので、筐体１０の底部１５から第１洗濯槽１１０の前部１１６を離間させて配置することが可能になる。その結果、第１洗濯槽１１０の前部１１６と底部１５との間に第１排水経路部１４０を配置するための第１空間Ｂ１を確保することが可能になる。 Further, since the first inclination angle θ1 is larger than the angle 0 °, the front portion 116 of the first washing tub 110 can be disposed away from the bottom portion 15 of the housing 10. As a result, it is possible to secure the first space B1 for arranging the first drainage path portion 140 between the front portion 116 and the bottom portion 15 of the first washing tub 110.
　続いて、図４を参照して、第２洗濯槽２１０について説明する。 Subsequently, the second washing tub 210 will be described with reference to FIG.
　図４に示すように、第２傾斜角度θ２は、角度０°以下である（第２傾斜角度θ２≦角度０°）。第１実施形態では、第２傾斜角度θ２は、角度略０°である（第２傾斜角度θ２≒角度０°）。従って、第１実施形態では、第２洗濯槽２１０の第２開口部２１３が略水平方向Ａを向くように配置される。その結果、ユーザーが、第２洗濯槽２１０に対して洗濯物を出し入れする第２作業を容易に行うことができる。理由は、ユーザーは、通常、第２洗濯槽２１０と略同じ高さの目線で第２作業を行うからである。 As shown in FIG. 4, the second inclination angle θ2 is 0 ° or less (second inclination angle θ2 ≦ angle 0 °). In the first embodiment, the second inclination angle θ2 is substantially 0 ° (second inclination angle θ2≈angle 0 °). Therefore, in the first embodiment, the second opening 213 of the second washing tub 210 is disposed so as to face the substantially horizontal direction A. As a result, the user can easily perform the second operation of putting the laundry in and out of the second washing tub 210. The reason is that the user usually performs the second work with a line of sight that is substantially the same height as the second washing tub 210.
　また、第２傾斜角度θ２が角度略０°の場合、第２洗濯槽２１０が略水平に設置される。第２洗濯槽２１０が略水平に設置されると、第２洗濯槽２１０の振動を容易にコントロールすることができる。従って、洗濯機１の稼働時に、第２洗濯槽２１０の振動により洗濯機１の上部がぐらつくことを抑制できる。その結果、洗濯機１の稼働時に、洗濯機１の姿勢をより安定させることが可能になる。 Further, when the second inclination angle θ2 is substantially 0 °, the second washing tub 210 is installed substantially horizontally. When the second washing tub 210 is installed substantially horizontally, the vibration of the second washing tub 210 can be easily controlled. Therefore, it is possible to prevent the upper portion of the washing machine 1 from wobbling due to the vibration of the second washing tub 210 when the washing machine 1 is in operation. As a result, the posture of the washing machine 1 can be further stabilized when the washing machine 1 is in operation.
　なお、第２傾斜角度θ２が角度０°よりも小さい場合（第２傾斜角度θ２＜角度０°）、第２洗濯槽２１０の第２開口部２１３が水平方向Ａよりも下向きに配置される。この場合、第２傾斜角度θ２は、例えば、角度－２°で、第２洗濯槽２１０の第２側部２１１が水平方向Ａよりも下向きに傾斜する。従って、第２洗濯槽２１０が洗濯物を洗濯する際、第２洗濯槽２１０内の洗濯物が洗濯物の自重で前方へ移動して第２扉３０に接触する。その結果、第２洗濯槽２１０は、洗濯物を第２扉３０に接触させつつ、第２洗濯槽２１０と共に回転させることができるので、洗濯物の汚れを効果的に落とすことが可能になる。 When the second inclination angle θ2 is smaller than the angle 0 ° (second inclination angle θ2 <angle 0 °), the second opening 213 of the second washing tub 210 is disposed downward from the horizontal direction A. In this case, the second inclination angle θ2 is, for example, an angle of −2 °, and the second side portion 211 of the second washing tub 210 is inclined downward from the horizontal direction A. Accordingly, when the second washing tub 210 is washing the laundry, the laundry in the second washing tub 210 moves forward due to the weight of the laundry and contacts the second door 30. As a result, the second washing tub 210 can be rotated together with the second washing tub 210 while bringing the laundry into contact with the second door 30, so that the laundry can be effectively cleaned.
　なお、第２傾斜角度θ２が角度０°よりも小さい場合、第２扉３０の内面３１に凹凸を形成してもよい。その結果、洗濯物を第２扉３０の凹凸に接触させつつ回転させることができるので、いわゆる洗濯板効果により洗濯物の汚れをより効果的に落とすことが可能になる。 Note that when the second inclination angle θ2 is smaller than the angle 0 °, irregularities may be formed on the inner surface 31 of the second door 30. As a result, the laundry can be rotated while being brought into contact with the unevenness of the second door 30, so that the laundry can be more effectively cleaned by the so-called washing board effect.
　なお、第１実施形態では、第１洗濯槽１１０の第１傾斜角度θ１は角度０°よりも大きいが、本発明はこれに限定されない。第１洗濯槽１１０の第１傾斜角度θ１は角度０°でもよい。その結果、第１洗濯槽１１０の振動を容易にコントロールすることができ、第１洗濯槽１１０の振動を抑制することが可能になる。この場合、第２洗濯槽２１０の第２傾斜角度θ２は、角度０°よりも小さい。この場合、第２洗濯槽２１０の第２傾斜角度θ２は、例えば、角度－２°に設定される。 In addition, in 1st Embodiment, although 1st inclination-angle (theta) 1 of the 1st washing tub 110 is larger than angle 0 degree, this invention is not limited to this. The first inclination angle θ1 of the first washing tub 110 may be an angle of 0 °. As a result, the vibration of the first washing tub 110 can be easily controlled, and the vibration of the first washing tub 110 can be suppressed. In this case, the second inclination angle θ2 of the second washing tub 210 is smaller than the angle 0 °. In this case, the second inclination angle θ2 of the second washing tub 210 is set to an angle of −2 °, for example.
［第２実施形態］
　図５及び図６を参照して、本発明の第２実施形態に係る洗濯機１について説明する。図５は、第２実施形態の洗濯機１の側面図である。図６は、洗濯機１の模式図である。 [Second Embodiment]
With reference to FIG.5 and FIG.6, the washing machine 1 which concerns on 2nd Embodiment of this invention is demonstrated. FIG. 5 is a side view of the washing machine 1 according to the second embodiment. FIG. 6 is a schematic diagram of the washing machine 1.
　第１実施形態では、背面部１３は略フラットな形状に形成される。これに対し、第２実施形態では、背面部１３が凹凸を有する形状に形成される点で第１実施形態と異なる。以下では、主に第１実施形態と異なる点を説明する。 In the first embodiment, the back surface portion 13 is formed in a substantially flat shape. On the other hand, the second embodiment is different from the first embodiment in that the back surface portion 13 is formed in a shape having irregularities. Hereinafter, differences from the first embodiment will be mainly described.
　図５及び図６に示すように、筐体１０は、第１筐体部１０ａと、第２筐体部１０ｂとを有する。第１筐体部１０ａは、筐体１０の下側部分を示す。第１筐体部１０ａは、第１洗濯槽１１０を収容する。第２筐体部１０ｂは、筐体１０の上側部分を示す。第２筐体部１０ｂは、第２洗濯槽２１０を収容する。 As shown in FIGS. 5 and 6, the housing 10 includes a first housing portion 10a and a second housing portion 10b. The first housing part 10 a shows the lower part of the housing 10. The first housing portion 10a houses the first washing tub 110. The second housing part 10 b shows the upper part of the housing 10. The second housing portion 10b accommodates the second washing tub 210.
　背面部１３は、第１洗濯槽１１０及び第２洗濯槽２１０を後方から覆う。背面部１３の上側部分は、背面部１３の下側部分よりも前方へ凹んでいる。 The back surface part 13 covers the 1st washing tub 110 and the 2nd washing tub 210 from back. The upper portion of the back surface portion 13 is recessed forward than the lower portion of the back surface portion 13.
　背面部１３は、第１背面部１３ａと、第２背面部１３ｂとを有する。 The back surface portion 13 has a first back surface portion 13a and a second back surface portion 13b.
　第１背面部１３ａは、背面部１３の下側部分である。第１背面部１３ａは、第１洗濯槽１１０の後方に配置される。 The first back surface portion 13 a is a lower portion of the back surface portion 13. The first back surface portion 13 a is disposed behind the first washing tub 110.
　第２背面部１３ｂは、背面部１３の上側部分である。第２背面部１３ｂは、第２洗濯槽２１０の後方に配置される。第２背面部１３ｂは、第１背面部１３ａよりも前方に位置する。 The second back surface portion 13 b is an upper portion of the back surface portion 13. The second back surface portion 13 b is disposed behind the second washing tub 210. The 2nd back surface part 13b is located ahead of the 1st back surface part 13a.
　背面部１３は、凹み部１３ｃをさらに有する。凹み部１３ｃは、第２背面部１３ｂのうち少なくとも一部に形成される。凹み部１３ｃは、第１背面部１３ａよりも前方に凹む。第２実施形態では、凹み部１３ｃは、第２背面部１３ｂの全部に形成される。従って、第２実施形態では、第２背面部１３ｂの全部が、第１背面部１３ａよりも前方に位置する。 The back surface part 13 further has a recessed part 13c. The recessed portion 13c is formed in at least a part of the second back surface portion 13b. The recessed portion 13c is recessed forward than the first back surface portion 13a. In the second embodiment, the recessed portion 13c is formed on the entire second back surface portion 13b. Therefore, in 2nd Embodiment, all the 2nd back surface parts 13b are located ahead of the 1st back surface part 13a.
　背面部１３に凹み部１３ｃが形成されると、第２筐体部１０ｂの容積が第１筐体部１０ａの容積よりも少なくなる。従って、載置面Ｄに対する第２筐体部１０ｂの投影面積が、載置面Ｄに対する第１筐体部１０ａの投影面積よりも小さくなる。その結果、洗濯機１の下側部分のサイズに比べて上側部分のサイズが小さくなるので、洗濯機１を安定して設置することができる。さらに、洗濯機１の振動に起因して洗濯機１の姿勢が不安定になることを抑制できる。なお、載置面Ｄは、洗濯機１が載置されている面を示す。 If the recessed part 13c is formed in the back surface part 13, the volume of the 2nd housing | casing part 10b will become smaller than the volume of the 1st housing | casing part 10a. Therefore, the projection area of the second housing part 10 b on the placement surface D is smaller than the projection area of the first housing part 10 a on the placement surface D. As a result, since the size of the upper part is smaller than the size of the lower part of the washing machine 1, the washing machine 1 can be installed stably. Furthermore, it is possible to suppress the posture of the washing machine 1 from becoming unstable due to the vibration of the washing machine 1. The placement surface D indicates the surface on which the washing machine 1 is placed.
　背面部１３は、凹み空間Ｃをさらに有する。凹み空間Ｃは、第２背面部１３ｂの後部に位置する空間のうち、第１背面部１３ａよりも前方に位置する部分を示す。凹み空間Ｃは、凹み部１３ｃの後部に位置する。第２背面部１３ｂに対して凹み部１３ｃが形成されることで、凹み空間Ｃが生成される。 The back surface portion 13 further has a recessed space C. The recessed space C indicates a portion located in front of the first back surface portion 13a in the space located in the rear portion of the second back surface portion 13b. The recessed space C is located at the rear portion of the recessed portion 13c. The recessed space C is generated by forming the recessed portion 13c with respect to the second back surface portion 13b.
　凹み空間Ｃには、水栓が配置可能である。水栓は、壁面に設置され、洗濯機１に水を供給する。従って、凹み空間Ｃに水栓を配置することで、水栓が第２背面部１３ｂに接触することを回避しつつ、第１背面部１３ａを壁面に近接させて配置することが可能になる。その結果、洗濯機１を壁面に近接させて配置することが可能になるので、洗濯機１の設置スペースの増加を抑制することが可能になる。 A faucet can be placed in the recessed space C. The faucet is installed on the wall surface and supplies water to the washing machine 1. Therefore, by disposing the faucet in the recessed space C, it is possible to dispose the first back surface portion 13a close to the wall surface while avoiding the faucet from contacting the second back surface portion 13b. As a result, since the washing machine 1 can be disposed close to the wall surface, an increase in the installation space of the washing machine 1 can be suppressed.
　なお、第２実施形態では、凹み部１３ｃは、第２背面部１３ｂの全部に形成される。しかし、凹み部１３ｃは、第２背面部１３ｂの一部に形成されてもよい。例えば、第２背面部１３ｂのうち、水栓と対向する部分にのみ凹み部１３ｃを形成してもよい。 In the second embodiment, the recessed portion 13c is formed on the entire second back surface portion 13b. However, the recessed portion 13c may be formed in a part of the second back surface portion 13b. For example, you may form the recessed part 13c only in the part which opposes a faucet among the 2nd back surface parts 13b.
　次に、図６を参照して、凹み空間Ｃを形成するための原理について説明する。 Next, the principle for forming the recessed space C will be described with reference to FIG.
　図６に示すように、第２洗濯槽２１０の前後方向の寸法β１は、第１洗濯槽１１０の前後方向の寸法α１よりも短い（寸法β１＜寸法α１）。従って、第２洗濯槽２１０の後部２１５が、第１洗濯槽１１０の後部１１５よりも前方に配置される。その結果、第２背面部１３ｂを第１背面部１３ａよりも前方に配置して、凹み空間Ｃを形成することが可能になる。 As shown in FIG. 6, the dimension β1 in the front-rear direction of the second washing tub 210 is shorter than the dimension α1 in the front-rear direction of the first washing tub 110 (dimension β1 <dimension α1). Accordingly, the rear portion 215 of the second washing tub 210 is disposed in front of the rear portion 115 of the first washing tub 110. As a result, it is possible to form the recessed space C by disposing the second back surface portion 13b in front of the first back surface portion 13a.
　第１実施形態では、第２洗濯槽２１０の寸法β２は、第１洗濯槽１１０の寸法α２よりも小さい（寸法β２＜寸法α２）。従って、第２洗濯槽２１０が第１洗濯槽１１０よりも小型である。その結果、より確実に凹み空間Ｃを形成することが可能になる。なお、第１洗濯槽１１０の寸法α２は、詳細には、第１回転軸１１４に沿った第１洗濯槽１１０の寸法を示す。第２洗濯槽２１０の寸法β２は、詳細には、第２回転軸２１４に沿った第２洗濯槽２１０の寸法を示す。 In the first embodiment, the dimension β2 of the second washing tub 210 is smaller than the dimension α2 of the first washing tub 110 (dimension β2 <dimension α2). Therefore, the second washing tub 210 is smaller than the first washing tub 110. As a result, the recessed space C can be more reliably formed. The dimension α2 of the first washing tub 110 indicates the dimension of the first washing tub 110 along the first rotation shaft 114 in detail. Specifically, the dimension β2 of the second washing tub 210 indicates the dimension of the second washing tub 210 along the second rotation axis 214.
　なお、第２洗濯槽２１０の寸法β２は、第１洗濯槽１１０の寸法α２と同じでもよい（寸法β２＝寸法α２）。つまり、第２洗濯槽２１０のサイズが、第１洗濯槽１１０のサイズと同じでもよい。この場合でも、第１傾斜角度θ１が第２傾斜角度θ２よりも大きいので（第１傾斜角度θ１＞第２傾斜角度θ２）、第２洗濯槽２１０の寸法β１を、第１洗濯槽１１０の寸法α１よりも小さくすることが可能である（寸法β１＜寸法α１）。 The dimension β2 of the second washing tub 210 may be the same as the dimension α2 of the first washing tub 110 (dimension β2 = dimension α2). That is, the size of the second washing tub 210 may be the same as the size of the first washing tub 110. Even in this case, since the first inclination angle θ1 is larger than the second inclination angle θ2 (first inclination angle θ1> second inclination angle θ2), the dimension β1 of the second washing tub 210 is set to the dimension of the first washing tub 110. It is possible to make it smaller than α1 (dimension β1 <dimension α1).
［第３実施形態］
　図７を参照して、本発明の第３実施形態に係る洗濯機１について説明する。図７は、第３実施形態の洗濯機１の側面図である。 [Third Embodiment]
With reference to FIG. 7, the washing machine 1 which concerns on 3rd Embodiment of this invention is demonstrated. FIG. 7 is a side view of the washing machine 1 according to the third embodiment.
　第３実施形態は、洗濯機１の側面の凹凸を抑制している点で第２実施形態と異なる。以下では、主に第２実施形態と異なる点を説明する。 The third embodiment is different from the second embodiment in that unevenness on the side surface of the washing machine 1 is suppressed. Hereinafter, differences from the second embodiment will be mainly described.
　図７に示すように、洗濯機１は、一対のカバー部５０をさらに備える。 As shown in FIG. 7, the washing machine 1 further includes a pair of cover portions 50.
　一対のカバー部５０の各々は、平板状の部材である。一対のカバー部５０は、それぞれ、一対の側面部１２に固定される。なお、カバー部５０は側面部１２の部材の一部として一つの部品にて形成しても良い。 Each of the pair of cover parts 50 is a flat member. The pair of cover portions 50 are respectively fixed to the pair of side surface portions 12. Note that the cover unit 50 may be formed as one part as a part of the member of the side surface unit 12.
　一対のカバー部５０は、左右方向に間隔を空けて互いに対向する。以下では、一対のカバー部５０のうちの１つに着目して説明する。 The pair of cover portions 50 face each other with a gap in the left-right direction. Below, it demonstrates paying attention to one of a pair of cover parts 50. FIG.
　カバー部５０は、凹み部１３ｃに対して側方から対向する。カバー部５０は、凹み空間Ｃを側方から覆う。カバー部５０の後部５１は、第１背面部１３ａに沿って、上下方向に延びる。従って、洗濯機１を側方から見て、凹み部１３ｃにより生じた背面部１３の凹凸を、カバー部５０により隠すことが可能である。その結果、洗濯機１を側方から見たときの洗濯機１の美観を向上させることが可能になる。 The cover part 50 faces the recessed part 13c from the side. The cover part 50 covers the recessed space C from the side. The rear portion 51 of the cover portion 50 extends in the vertical direction along the first back surface portion 13a. Therefore, when the washing machine 1 is viewed from the side, the unevenness of the back surface portion 13 caused by the recessed portion 13 c can be hidden by the cover portion 50. As a result, it is possible to improve the beauty of the washing machine 1 when the washing machine 1 is viewed from the side.
　以上、図面（図１～図７）を参照しながら本発明の実施形態について説明した。但し、本発明は、上記の実施形態に限られるものではなく、その要旨を逸脱しない範囲で種々の態様において第４実施形態として実施することが可能である（例えば、（１））。また、上記の実施形態に開示されている複数の構成要素を適宜組み合わせることによって、種々の発明の形成が可能である。例えば、実施形態に示される全構成要素から幾つかの構成要素を削除してもよい。図面は、理解しやすくするために、それぞれの構成要素を主体に模式的に示しており、図示された各構成要素の個数等は、図面作成の都合から実際とは異なる場合もある。また、上記の実施形態で示す各構成要素は一例であって、特に限定されるものではなく、本発明の効果から実質的に逸脱しない範囲で種々の変更が可能である。 The embodiment of the present invention has been described above with reference to the drawings (FIGS. 1 to 7).
