Description

美容器具Beauty equipment
　本発明は、肌の美容のために用いる美容器具に関する。 The present invention relates to a beauty instrument used for skin beauty.
　肌の美容を目的とする美容器具の中で、加温されたローラーを肌に押し当てつつ転がして用いる美容器具がある。この美容器具は、ローラーにより押圧される作用と、肌を温める作用との双方の作用により、肌の血行を促進させることができる。上記美容器具は、肌のしわやたるみ、あるいは目元のくま等を改善する目的で用いられる。 Among beauty instruments for the purpose of skin beauty, there are beauty instruments that are used by rolling while pressing a heated roller against the skin. This beauty instrument can promote the blood circulation of the skin by both the action of being pressed by the roller and the action of warming the skin. The beauty instrument is used for the purpose of improving wrinkles and sagging of the skin, or bears around the eyes.
　上記美容器具の例として、特許文献１には、回転可能に設置する肉厚ゲルマニウム製のローラー本体と、ローラー本体を保持する把持部材と、ローラー本体内部に配置したヒーターとを有するローラーマッサージ器が開示されている。 As an example of the beauty tool, Patent Document 1 discloses a roller massager having a roller body made of thick germanium that is rotatably installed, a gripping member that holds the roller body, and a heater disposed inside the roller body. It is disclosed.
　また、近年では、例えば旅行や出張等の外出時に携帯できるような、携帯性に優れた上記美容器具が望まれている。 Also, in recent years, there has been a demand for the above-described beauty equipment with excellent portability that can be carried when going out, for example, on a trip or business trip.
特開２００８－３６２４７号公報JP 2008-36247 A
　しかしながら、特許文献１のローラーマッサージ器は、肌に接触するローラー本体部とヒーターとの間に、パイプ及び保持部材の２つの部材が介在しており、熱容量が大きい。それ故、ローラー本体部を所望の温度まで加温するために比較的大きな電力を必要とするという問題がある。 However, the roller massager of Patent Document 1 has a large heat capacity because two members, a pipe and a holding member, are interposed between the roller main body portion that contacts the skin and the heater. Therefore, there is a problem that relatively large electric power is required to heat the roller main body to a desired temperature.
　一方、携帯性を高める観点からは、小型かつ軽量な美容器具が好ましい。しかしながら、特許文献１のローラーマッサージ器は、比較的大きな電力を必要とするため、電源部の小型化及び軽量化が困難である。それ故、携帯して使用する用途には適さない。 On the other hand, from the viewpoint of improving portability, a small and lightweight beauty device is preferable. However, since the roller massager of patent document 1 requires comparatively big electric power, size reduction and weight reduction of a power supply part are difficult. Therefore, it is not suitable for a portable use.
　本発明は、かかる背景に鑑みてなされたものであり、携帯性に優れた美容器具を提供しようとするものである。 The present invention has been made in view of such a background, and intends to provide a beauty device having excellent portability.
　皮膚に接触させる筒状の側壁部を有するローラーと、
　該ローラーを回転可能に支持するローラー受け部を有するハンドルと、
　該ハンドルに内蔵され、電力を供給するオン状態と電力を遮断するオフ状態とを切り替え可能に構成された電源部と、
　上記側壁部に熱的に接触し、上記オン状態において発熱するシート状発熱体とを有することを特徴とする美容器具にある。 A roller having a cylindrical side wall to be brought into contact with the skin;
A handle having a roller receiver that rotatably supports the roller;
A power supply unit built in the handle and configured to be able to switch between an on state for supplying power and an off state for cutting off power;
A beauty device having a sheet-like heating element that is in thermal contact with the side wall and generates heat in the ON state.
　上記美容器具は、上記側壁部に熱的に接触し、上記オン状態において発熱するシート状発熱体（以下、「発熱体」と省略することがある。）を有している。そのため、上記発熱体からの熱を上記側壁部に効率よく伝達することができ、上記側壁部を比較的低い消費電力で十分に加温することができる。その結果、上記美容器具における電源部の小型化及び軽量化を容易に行うことができ、ひいては美容器具全体の小型化及び軽量化を容易に行うことができる。 The beauty tool has a sheet-like heating element (hereinafter sometimes abbreviated as “heating element”) that is in thermal contact with the side wall and generates heat in the ON state. Therefore, the heat from the heating element can be efficiently transmitted to the side wall, and the side wall can be sufficiently heated with relatively low power consumption. As a result, it is possible to easily reduce the size and weight of the power supply unit in the beauty tool, and thus easily reduce the size and weight of the entire beauty tool.
　以上のように、上記美容器具は、小型化及び軽量化を容易に行うことができる。それ故、上記美容器具は、優れた携帯性を有する。 As described above, the beauty tool can be easily reduced in size and weight. Therefore, the beauty instrument has excellent portability.
実施例における、美容器具の斜視図。The perspective view of the beauty instrument in an Example. 実施例における、美容器具の部品展開図。The components expanded view of the beauty instrument in an Example. 実施例における、美容器具を電源ボタン側から見た平面図。The top view which looked at the beauty instrument in the Example from the power button side. 図３のIV－IV線矢視断面図。FIG. 4 is a sectional view taken along line IV-IV in FIG. 3. 図４のV－V線一部矢視断面図。FIG. 5 is a partial cross-sectional view taken along line VV in FIG. 4. 実施例における、シート状発熱体として用いた発熱フィルムの平面図。The top view of the heat generating film used as a sheet-like heat generating body in an Example.
　上記美容器具において、熱的に接触とは、発熱体の少なくとも一部が側壁部の内表面に直接接触している状態に限らず、発熱体と側壁部との間に熱抵抗の小さいフィルム状部材や高い熱伝導率を有する部材が介在している状態を含む。 In the beauty tool, the thermal contact is not limited to a state in which at least a part of the heating element is in direct contact with the inner surface of the side wall, but a film shape having a low thermal resistance between the heating element and the side wall. This includes a state in which a member or a member having high thermal conductivity is interposed.
　また、上記シート状発熱体は、筒状に巻き回された状態でローラーの内部空間に配置されると共に、発熱体自身の弾性力により側壁部の内表面に向けて付勢されていることが好ましい。この場合には、発熱体が上記弾性力により側壁部側へ押し付けられるため、側壁部等の内表面と発熱体との接触面積がより広くなり易い。そのため、発熱体から側壁部への熱の伝達効率をより向上させることができ、側壁部をより小さな消費電力で十分に加温することができる。それ故、上記美容器具は、より優れた携帯性を有するものとなりやすい。 Further, the sheet-like heating element is disposed in the inner space of the roller in a state of being wound in a cylindrical shape, and is urged toward the inner surface of the side wall portion by the elastic force of the heating element itself. preferable. In this case, since the heating element is pressed against the side wall by the elastic force, the contact area between the inner surface of the side wall or the like and the heating element is likely to be wider. Therefore, the heat transfer efficiency from the heating element to the side wall can be further improved, and the side wall can be sufficiently heated with less power consumption. Therefore, the beauty tool tends to have more excellent portability.
　また、この場合には、発熱体を側壁部側へ押し付けるための構造をローラー内に設ける必要がないため、ローラーの構造をより簡素にすることができる。その結果、上記美容器具全体の生産性をより向上させることができる。 In this case, since it is not necessary to provide a structure for pressing the heating element against the side wall portion in the roller, the structure of the roller can be further simplified. As a result, the productivity of the entire beauty tool can be further improved.
　また、発熱体は側壁部の内表面における略全面と熱的に接触していることが好ましい。この場合には、側壁部の内表面における全面を発熱体からの熱伝達に利用することができる。そのため、発熱体から側壁部への熱の伝達効率がほぼ最大となり、側壁部をより小さな消費電力で十分に加温することができる。その結果、上記美容器具は、より優れた携帯性を有するものとなる。 Further, the heating element is preferably in thermal contact with substantially the entire inner surface of the side wall. In this case, the entire inner surface of the side wall can be used for heat transfer from the heating element. Therefore, the heat transfer efficiency from the heating element to the side wall portion is substantially maximized, and the side wall portion can be sufficiently heated with smaller power consumption. As a result, the beauty tool has better portability.
　また、上記側壁部の両端には端板部が配置されており、端板部はローラーの内部空間側に立設された発熱体規制部を有しており、発熱体規制部と側壁部との間にシート状発熱体の端部が配されていてもよい。この場合には、例えば発熱体の自重や振動等によって発熱体が側壁部から離れる方向に変形しようとする場合に、発熱体の端部が上記発熱体規制部と上記側壁部との間に規制される。これにより、発熱体と側壁部との間に生じる隙間が過度に大きくなることを抑制でき、ひいては側壁部の加温が不十分となることを抑制できる。その結果、上記美容器具は、使用者に優れた美容効果を安定して体感させることができる。 Further, end plate portions are disposed at both ends of the side wall portion, and the end plate portion has a heating element restricting portion erected on the inner space side of the roller, and the heating element restricting portion, the side wall portion, An end portion of the sheet-like heating element may be disposed between the two. In this case, for example, when the heating element tends to be deformed away from the side wall due to its own weight or vibration, the end of the heating element is regulated between the heating element regulation part and the side wall part. Is done. Thereby, it can suppress that the clearance gap produced between a heat generating body and a side wall part becomes large too much, and can suppress that the heating of a side wall part becomes inadequate by extension. As a result, the said beauty instrument can make a user experience the beauty effect excellent in the user stably.
　また、端板部はシート状発熱体と電気的に接続されたローラー側電極をローラーの外側に有しており、ローラー受け部は、電源部と電気的に接続されたハンドル側電極を有しており、ハンドル側電極とローラー側電極とが互いに接触していてもよい。この場合には、発熱体は、ローラー側電極及びハンドル側電極を含む電流経路により、電源部と電気的に接続される。そして、発熱体は、電源部からの電力供給を受けるための配線をローラーの外部まで伸ばす必要がない。それ故、ローラーは、上記配線のねじれ等により回転を規制されることなく、自由に回転することができる。その結果、上記美容器具は、使用者にとってより扱い易いものとなる。 Further, the end plate portion has a roller side electrode electrically connected to the sheet-like heating element on the outside of the roller, and the roller receiving portion has a handle side electrode electrically connected to the power source portion. The handle side electrode and the roller side electrode may be in contact with each other. In this case, the heating element is electrically connected to the power supply unit through a current path including the roller side electrode and the handle side electrode. And a heating element does not need to extend the wiring for receiving the electric power supply from a power supply part to the exterior of a roller. Therefore, the roller can freely rotate without being restricted in rotation by the twist of the wiring or the like. As a result, the beauty tool is easier to handle for the user.
　また、ハンドルは略棒状を呈しており、一対の上記ローラー受け部は上記ハンドルの端部に立設されており、ローラーは、その回転軸をハンドルの長手方向に直交する方向に向けた状態で一対のローラー受け部に支持されていてもよい。この場合には、使用者は、ハンドルを往復移動させることにより、肌を押圧しつつ肌に押し当てたローラーを容易に回転させることができる。 Further, the handle has a substantially rod shape, the pair of roller receiving portions are erected on the end of the handle, and the roller is in a state where its rotation axis is directed in a direction perpendicular to the longitudinal direction of the handle. You may be supported by a pair of roller receiving part. In this case, the user can easily rotate the roller pressed against the skin while pressing the skin by reciprocating the handle.
　また、この場合には、側壁部におけるハンドルに対面する部分、すなわちハンドルが障害となって肌に接触させることができない部分の面積が狭くなり、肌と接触可能な部分の面積を相対的に広くすることができる。そのため、使用者は、ローラーを肌に接触させる際の美容器具の姿勢をより自由に選択することができる。以上の結果、上記美容器具は、使用者にとってより扱い易いものとなる。 Further, in this case, the area of the side wall facing the handle, that is, the area where the handle becomes an obstacle and cannot be brought into contact with the skin is narrowed, and the area of the part that can be contacted with the skin is relatively wide. can do. Therefore, the user can more freely select the posture of the beauty tool when the roller is brought into contact with the skin. As a result, the beauty tool is easier to handle for the user.
　また、一対のローラー受け部はハンドルの長手方向に対して斜め方向に向かって立設されており、ローラーの側壁部の少なくとも一部がハンドルよりも外方まで膨出していてもよい。すなわち、ローラーの回転軸方向から見たときに、一対のローラー受け部がハンドルに対して斜め方向に突出しており、かつ、側壁部の少なくとも一部がハンドルの外表面よりも膨出していてもよい。この場合には、使用者は、側壁部におけるハンドルよりも外方まで膨出した側を肌に向けることにより、より容易にローラーを肌に押し当てることができる。その結果、上記美容器具は、使用者にとってより扱い易いものとなる。 Further, the pair of roller receiving portions may be erected in an oblique direction with respect to the longitudinal direction of the handle, and at least a part of the side wall portion of the roller may bulge outward from the handle. That is, when viewed from the rotation axis direction of the roller, the pair of roller receiving portions protrude obliquely with respect to the handle, and at least a part of the side wall portion bulges from the outer surface of the handle. Good. In this case, the user can more easily press the roller against the skin by directing the side bulging outward from the handle on the side wall to the skin. As a result, the beauty tool is easier to handle for the user.
　また、上記ローラーは、上記オン状態において発光する発光体を内部空間に有しており、側壁部及びシート状発熱体は上記発光体からの光を透過するよう構成されていてもよい。この場合には、使用者は、上記美容器具がオン状態であるか否かを、上記発光体の発光の有無により視覚的に判断することができる。その結果、使用者が上記美容器具を誤ってオン状態にすることを容易に防止でき、誤動作等による電力の浪費を容易に抑制することができる。 Further, the roller may have a light emitter that emits light in the ON state in the internal space, and the side wall portion and the sheet-like heating element may be configured to transmit light from the light emitter. In this case, the user can visually determine whether or not the beauty tool is in an on state based on whether or not the light emitter emits light. As a result, it is possible to easily prevent the user from erroneously turning on the beauty tool, and it is possible to easily suppress the waste of power due to a malfunction or the like.
　また、この場合には、誤動作等による電力の浪費を抑制することができる。そのため、上記美容器具が電力源として電池を使用している場合には、より長時間の連続使用が可能である。それ故、上記美容器具は、より優れた携帯性を有するものとなりやすい。 In this case, power consumption due to malfunctions can be suppressed. For this reason, when the beauty instrument uses a battery as a power source, it can be used continuously for a longer time. Therefore, the beauty tool tends to have more excellent portability.
　上記発光体としては、例えば白熱電球や発光ダイオード素子等が用いられる。消費電力の低減及び美容器具の小型化の観点からは、発光体として発光ダイオード素子を用いることが好ましい。 For example, an incandescent bulb or a light emitting diode element is used as the light emitter. From the viewpoint of reducing power consumption and downsizing the beauty tool, it is preferable to use a light emitting diode element as the light emitter.
　また、上記透過光は、上記側壁部を透過した後に暖色を呈するよう構成されていてもよい。ここで、暖色とは、例えば赤色、朱色、橙色、桃色、黄色などを含み、一般的な感覚として視認することにより温かみを感じる色をいう。この場合には、暖色の透過光を視認することによる心理的な作用により、上記美容器具は肌に接触した上記側壁部の温感をより効果的に使用者に体感させることができ、ひいては優れた美容効果を体感させることができる。 Further, the transmitted light may be configured to exhibit a warm color after passing through the side wall portion. Here, the warm color refers to a color that feels warm when visually recognized as a general sense, including red, vermilion, orange, pink, yellow, and the like. In this case, due to the psychological action by visually recognizing the transmitted light of warm color, the beauty tool can make the user feel the warm feeling of the side wall part in contact with the skin more effectively, and thus excellent. You can feel the beauty effect.
　なお、上記透過光は、最終的に側壁部を透過した後に暖色を呈していればよい。透過光を暖色にする構成としては、例えば、暖色に発光する発光体を用いる構成、側壁部を暖色に着色することにより、側壁部を透過した光を暖色にする構成等がある。 The transmitted light only needs to exhibit a warm color after finally passing through the side wall. As a configuration for making the transmitted light warm, there are, for example, a configuration using a light emitting body that emits a warm color, and a configuration for making the light transmitted through the side wall portion warm by coloring the side wall portion in a warm color.
　上記シート状発熱体は、一対の透明樹脂フィルムと、一対の透明樹脂フィルムに挟まれた透明抵抗膜とを有しており、透明抵抗膜は酸化インジウムスズより構成されていることが好ましい。酸化インジウムスズよりなる透明抵抗膜は、通電時の温度が変動しにくく、一定の温度になり易い。そのため、上記美容器具は、側壁部の加温特性が変動しにくく、安定して優れた性能を示す。 The sheet-like heating element has a pair of transparent resin films and a transparent resistance film sandwiched between the pair of transparent resin films, and the transparent resistance film is preferably made of indium tin oxide. A transparent resistance film made of indium tin oxide is less likely to change in temperature when energized, and is likely to have a constant temperature. For this reason, the beauty tool is not easily changed in the heating characteristics of the side wall portion, and stably exhibits excellent performance.
　また、上記美容器具が発光体を有する場合には、発光体からの光が透明抵抗膜及び一対の透明樹脂フィルムを透過する。そのため、発光体からの光がシート状発熱体による減衰を受けにくい。それ故、透過光の光量が十分に大きくなり、透過光がより視認され易くなる。その結果、使用者は、上記美容器具がオン状態であるか否かの判断をより容易に行うことができる。 Further, when the beauty tool has a light emitter, light from the light emitter passes through the transparent resistance film and the pair of transparent resin films. Therefore, the light from the light emitter is not easily attenuated by the sheet-like heating element. Therefore, the amount of transmitted light becomes sufficiently large, and the transmitted light is more easily visible. As a result, the user can more easily determine whether or not the beauty tool is on.
　また、シート状発熱体としては、上述した構成を有するもの以外に、通電により発熱すると共に、発熱体からの光を側壁部側に透過するよう構成されているものを用いることができる。シート状発熱体としては、例えば、少なくとも一部に透明な部分を有する発熱フィルムや、電熱線等の抵抗体が網状に配置された網状抵抗体等を用いることができる。 Further, as the sheet-like heating element, in addition to the sheet heating element, a sheet heating element that generates heat when energized and transmits light from the heating element to the side wall can be used. As the sheet-like heating element, for example, a heating film having a transparent part at least in part, a mesh resistor in which resistors such as heating wires are arranged in a mesh pattern, or the like can be used.
　また、上記発光体の周囲には、該発光体からの光を拡散する光拡散部材が設けられていてもよい。この場合には、光拡散部材により拡散された光が上記側壁部の全面を透過しやすくなり、上記オン状態において、上記側壁部の略全面が発光した状態となる。そのため、使用者は、透過光をより容易に視認することができ、ひいては上記美容器具がオン状態であるか否かを判断し易くなる。その結果、上記美容器具は、より扱い易いものとなる。 Further, a light diffusing member for diffusing light from the light emitter may be provided around the light emitter. In this case, the light diffused by the light diffusing member is easily transmitted through the entire side wall portion, and in the on state, substantially the entire side wall portion emits light. Therefore, the user can visually recognize the transmitted light more easily, and as a result, it is easy to determine whether or not the beauty tool is in the on state. As a result, the beauty tool becomes easier to handle.
　光拡散部材としては、例えば、光を拡散させる作用を有する光拡散フィルム等を用いることができる。また、ローラーの側壁部やシート状発熱体等が光拡散部材としての機能を有する構成であってもよい。かかる構成としては、例えば、シート状発熱体または側壁部に光を拡散させるためのコーティング層を設ける構成や、光を拡散させる作用を有する樹脂を用いて側壁部等を形成する構成等がある。また、光を拡散させる作用を実現する具体的な手段としては、ハーフミラー等により光を多重に反射させる手段や、微粒子顔料等により光を散乱させる手段などがある。 As the light diffusion member, for example, a light diffusion film having an action of diffusing light can be used. Moreover, the structure which the side wall part of a roller, a sheet-like heat generating body, etc. have a function as a light-diffusion member may be sufficient. Examples of such a configuration include a configuration in which a coating layer for diffusing light is provided on the sheet-like heating element or the side wall portion, a configuration in which the side wall portion is formed using a resin having an action of diffusing light. Specific means for realizing the action of diffusing light include means for reflecting light multiple times with a half mirror and the like, means for scattering light with fine particle pigments and the like.
　また、上記ハンドルは、上記オン状態と上記オフ状態とを切り替えるスイッチ部と、上記オン状態が所定時間継続した場合に上記オン状態から上記オフ状態への切り替えを行うタイマー部とを有する制御部を有していてもよい。この場合には、上記美容器具は、例えば使用者が誤ってスイッチ部を操作した場合等に、上記オン状態が所定時間を越えて継続することがない。それ故、上記美容器具は、誤動作による電力の浪費を低減でき、より長期にわたって使用可能なものとなる。 Further, the handle includes a control unit having a switch unit that switches between the on state and the off state, and a timer unit that switches from the on state to the off state when the on state continues for a predetermined time. You may have. In this case, in the beauty tool, for example, when the user mistakenly operates the switch unit, the ON state does not continue beyond the predetermined time. Therefore, the beauty tool can reduce power consumption due to malfunction and can be used for a longer period of time.
　なお、上記所定時間が過度に長いと電力の浪費を低減する効果が損なわれやすい。その反面、上記所定時間が過度に短いと、美容器具の使用途中でオフ状態に切り替わるおそれがあるため、使用者にとって扱いにくいものとなるおそれがある。そのため、電力の浪費の低減と、使用者の扱い易さとを両立させる観点から、上記所定時間は、例えば５～２０分の範囲とすることができる。 It should be noted that if the predetermined time is excessively long, the effect of reducing power consumption is likely to be impaired. On the other hand, if the predetermined time is excessively short, there is a risk of switching to an off state during use of the beauty tool, which may be difficult for the user to handle. For this reason, the predetermined time can be set in a range of, for example, 5 to 20 minutes from the viewpoint of achieving both reduction of waste of electric power and ease of handling by the user.
　上記美容器具の実施例について、図１～図６を用いて説明する。美容器具１は、図１～図５に示すように、ローラー２と、ハンドル３と、電源部４と、発光体５１と、シート状発熱体としての発熱フィルム６とを有している。ローラー２は、図２及び図５に示すように、皮膚に接触させる筒状の側壁部２１及び側壁部２１の両端に配置される端板部２２を有している。 Examples of the beauty tool will be described with reference to FIGS. As shown in FIGS. 1 to 5, the beauty tool 1 includes a roller 2, a handle 3, a power supply unit 4, a light emitter 51, and a heat generating film 6 as a sheet-shaped heat generator. As shown in FIGS. 2 and 5, the roller 2 has a cylindrical side wall portion 21 to be brought into contact with the skin and end plate portions 22 arranged at both ends of the side wall portion 21.
　図１～図３及び図５に示すように、ハンドル３は、ローラー２を回転可能に支持するローラー受け部３１を有している。図２及び図４に示すように、電源部４はハンドル３に内蔵されており、電力を供給するオン状態と電力を遮断するオフ状態とを切り替え可能に構成されている。図５に示すように、発光体５１は、ローラー２の内部空間２０に配置され、オン状態において発光するよう構成されている。発熱フィルム６は、側壁部２１に熱的に接触し、オン状態において発熱するよう構成されている。また、側壁部２１及び発熱フィルム６は発光体５１からの光を透過するよう構成されており、側壁部２１を透過した透過光が暖色を呈する。以下、詳説する。 As shown in FIG. 1 to FIG. 3 and FIG. 5, the handle 3 has a roller receiving portion 31 that rotatably supports the roller 2. As shown in FIGS. 2 and 4, the power supply unit 4 is built in the handle 3 and can be switched between an on state for supplying power and an off state for interrupting power. As shown in FIG. 5, the light emitter 51 is arranged in the internal space 20 of the roller 2 and is configured to emit light in the ON state. The heat generating film 6 is configured to be in thermal contact with the side wall portion 21 and generate heat in the ON state. Moreover, the side wall part 21 and the heat generating film 6 are configured to transmit light from the light emitter 51, and the transmitted light transmitted through the side wall part 21 exhibits a warm color. The details will be described below.
　図１及び図３に示すように、美容器具１は棒状を呈しており、その一端にローラー２を有している。ローラー２は、ハンドル３に設けられた一対のローラー受け部３１の間において回転可能に支持されている。また、ローラー２の回転軸２３は、美容器具１の長手方向に直交する方向を向いている。 As shown in FIGS. 1 and 3, the beauty tool 1 has a rod shape and has a roller 2 at one end thereof. The roller 2 is rotatably supported between a pair of roller receiving portions 31 provided on the handle 3. Further, the rotation shaft 23 of the roller 2 faces the direction orthogonal to the longitudinal direction of the beauty tool 1.
　なお、以下において、美容器具１の長手方向におけるローラー２側を「前方」といい、ローラー２の反対側を「後方」ということがある。また、ローラー２の回転軸２３が伸びる方向を「側方方向」ということがある。また、前後方向及び側方方向の双方に直交する方向を「上下方向」ということがある。美容器具１の方向に関するこれらの記載は便宜上のものであり、美容器具１を実際に使用する際の向きとは何ら関係がない。 In the following, the roller 2 side in the longitudinal direction of the beauty tool 1 may be referred to as “front”, and the opposite side of the roller 2 may be referred to as “rear”. Further, the direction in which the rotation shaft 23 of the roller 2 extends may be referred to as a “lateral direction”. In addition, a direction orthogonal to both the front-rear direction and the side direction may be referred to as “vertical direction”. These descriptions regarding the direction of the beauty tool 1 are for convenience, and have nothing to do with the direction when the beauty tool 1 is actually used.
　図１及び図３に示すように、ハンドル３は略棒状を呈している。図２及び図４に示すように、ハンドル３の内部には、電源部４及び制御部７が配置されている。電源部４には、電力源として用いられる電池４２が装着される。電池４２は、接点金具４１を介して制御部７に電気的に接続されている。 As shown in FIGS. 1 and 3, the handle 3 has a substantially rod shape.
