Abstract

To provide a coating film transfer tool having a simple structure, preventing sound generation, and having a reverse rotation prevention mechanism in which the amount of rewinding of the transfer tape is very small.SOLUTION: The coating film transfer tool includes a rotating member with a reverse rotation prevention claw that engages with the ratchet gear of a core (feeding core or winding core), and an elastic member that is crimped to the outer periphery of the core by self-elastic force and rotates with the core. The rotating member can rotate between the position where the reverse rotation prevention claw engages with the ratchet gear and the position where it does not engage. When the elastic member rotates in the reverse direction with the core, a pressing piece of the elastic member rotates the rotating member, and the reverse rotation prevention claw engages with the ratchet gear. When the elastic member rotates in the normal direction together with the core, the elastic member comes into contact with a stop portion and is stopped after the pressure of the pressing piece of the elastic member to the rotating member is released, or the pressing piece rotates integrally with the rotating member, so that the reverse rotation prevention claw of the rotating member is disengaged or can be disengaged from the ratchet gear.SELECTED DRAWING: Figure 1

Description

本発明は、文字修正用塗膜、接着用の粘着剤塗膜、装飾用塗膜等を被転写体の被転写面に押圧転写するための塗膜転写具の技術分野に属する。 The present invention belongs to the technical field of a coating film transfer tool for press-transferring a character correction coating film, an adhesive coating film for adhesion, a decorative coating film, etc. to the transfer surface of a transfer target.

塗膜転写具では、繰出コアから繰り出された転写テープ上の塗膜を、転写ヘッド先端で被転写体へ転写し、塗膜が無くなった転写テープ（基材テープ）を巻取コアに巻き取ることにより、塗膜転写を行っている。 In the coating film transfer tool, the coating film on the transfer tape unwound from the feeding core is transferred to the transfer target by the tip of the transfer head, and the transfer tape (base material tape) having no coating film is wound around the winding core. As a result, the coating film is transferred.

塗膜転写を終え、前記転写ヘッドを被転写体から持ち上げることにより、被転写体へ転写された塗膜と転写テープ上の塗膜が、前記転写ヘッドの先端で切断される。転写ヘッド先端で切断された転写テープ上の塗膜が、転写ヘッドの先端に留まっていれば、次に転写ヘッド先端を被転写体へ押し当てた位置から、確実に塗膜が被転写体へ転写される。このため、転写ヘッド先端で切断された転写テープ上の塗膜が、転写ヘッドの先端に留まっていれば、使用者が塗膜転写を開始したいと欲した位置から、塗膜転写を確実に開始することができる。しかしながら、塗膜転写具では、前記繰出コアと前記巻取コアを連動回転させる連動回転機構により、転写テープが繰出コア側へ巻き戻されることがある。 By finishing the coating film transfer and lifting the transfer head from the transfer target, the coating film transferred to the transfer target and the coating film on the transfer tape are cut at the tip of the transfer head. If the coating film on the transfer tape cut at the tip of the transfer head stays at the tip of the transfer head, the coating film is surely transferred to the transfer target from the position where the tip of the transfer head is pressed against the transfer target. Transcribed. Therefore, if the coating film on the transfer tape cut at the tip of the transfer head stays at the tip of the transfer head, the coating film transfer can be reliably started from the position where the user wants to start the coating film transfer. can do. However, in the coating film transfer tool, the transfer tape may be rewound to the feeding core side by the interlocking rotation mechanism that interlocks and rotates the feeding core and the winding core.

このような連動回転機構としては、繰出コアと巻取コアのそれぞれと同心円で回転するギア同士を噛合せたものや、繰出コアと巻取コアのそれぞれと同心円で回転するプーリー間にＯリングなどのベルトを掛けまわしたものがある。 Such interlocking rotation mechanisms include gears that rotate concentrically with each of the feeding core and the winding core, and an O-ring between pulleys that rotate concentrically with each of the feeding core and the winding core. There is one with a belt around.

ギア同士を噛合わせた連動回転機構では、ギアのバックラッシュにより、転写テープが繰出コア側へ巻き戻される。ベルトを掛けまわす連動回転機構では、繰出コアと同心円で回転するプーリー（繰出コアのプーリー）が引っ張る側のベルトの張力よりも、繰出コアのプーリーが送り出す側のベルトの張力が小さくなるため、送り出す側のベルトにたるみが生じる。塗膜転写を終え、前記転写ヘッドを被転写体から持ち上げると、ベルトを引っ張る側とベルトを押し出す側のベルト張力差を解消しようとして、繰出コアのプーリーが逆回転する。このように、繰出コアのプーリーが逆回転するので、転写テープが繰出コア側へ巻き戻される。 In the interlocking rotation mechanism in which the gears are meshed with each other, the transfer tape is rewound to the feeding core side due to the backlash of the gears. In the interlocking rotation mechanism that hangs the belt, the tension of the belt on the side where the pulley of the feeding core sends out is smaller than the tension of the belt on the pulling side of the pulley (pulley of the feeding core) that rotates concentrically with the feeding core. There is slack in the belt on the side. When the transfer head is lifted from the transferred body after the coating film transfer is completed, the pulley of the feeding core rotates in the reverse direction in an attempt to eliminate the difference in belt tension between the side that pulls the belt and the side that pushes the belt. In this way, the pulley of the feeding core rotates in the reverse direction, so that the transfer tape is rewound to the feeding core side.

転写テープが繰出コアに巻き戻されると、転写ヘッド先端の転写テープ上に塗膜がないため、使用者が塗膜転写を開始したいと欲した位置から、塗膜転写を開始することがでない。このため、例えば塗膜が修正テープの場合には、修正し始めようとした箇所に、修正テープの塗膜が転写されないことがある。また、塗膜を積層している転写テープの基材テープ表面は、塗膜を容易に剥離できるようにするため、平滑で摩擦係数が小さな面となっている。このため、塗膜が転写ヘッド先端にあるときにくらべて、転写テープが繰出コアに巻き戻されて転写ヘッド先端に塗膜がないときには、使用者が強い力で転写ヘッド先端を被転写体へ押し付けなければ転写テープを引き出すことができなくなる。このため、転写テープが繰出コアに巻き戻されて転写ヘッド先端の転写テープ上に塗膜がないときには、塗膜転写具は使い勝手が悪くなるという問題もある。 When the transfer tape is rewound to the feeding core, there is no coating film on the transfer tape at the tip of the transfer head, so that the coating film transfer cannot be started from the position where the user wants to start the coating film transfer. Therefore, for example, when the coating film is a correction tape, the coating film of the correction tape may not be transferred to the place where the correction is to be started. Further, the surface of the base tape of the transfer tape on which the coating film is laminated is smooth and has a small friction coefficient so that the coating film can be easily peeled off. Therefore, compared to when the coating film is at the tip of the transfer head, when the transfer tape is rewound to the feeding core and there is no coating film at the tip of the transfer head, the user uses a stronger force to move the tip of the transfer head to the transfer target. If you do not press it, you will not be able to pull out the transfer tape. Therefore, when the transfer tape is rewound to the feeding core and there is no coating film on the transfer tape at the tip of the transfer head, there is also a problem that the coating film transfer tool becomes inconvenient to use.

このような問題を解決するために、塗膜転写具には従来から、繰出コアや、繰出コアと連動する巻取コアに逆転防止機構を設けて、転写テープが繰出コアへ巻き戻されることを防止してきた。塗膜転写具の逆転防止機構としては、転写テープの巻き戻し量をできるだけ小さくするために、図７に示すラチェット機構が一般的に用いられてきた。図７に、従来の逆転防止機構を有する塗膜転写具を示す。図７（ａ）は上ケースを取り外した状態の従来の逆転防止機構を有する塗膜転写具の正面図である。図７（ｂ）は、図７（ａ）のＹ－Ｙ断面図である。図７（ｃ）は従来の塗膜転写具の下ケース及び下ケースに設けられたラチェット歯車を示す図であり、図７（ｄ）は、従来の塗膜転写具の巻取コア及び巻取コアに設けられた逆転防止ツメを示す図である。ただし、図７（ｂ）は上ケースを取り付けた状態を示している。 In order to solve such a problem, the coating film transfer tool has conventionally provided a reverse rotation prevention mechanism in the feeding core and the winding core interlocking with the feeding core so that the transfer tape is rewound to the feeding core. I have prevented it. As the reverse rotation prevention mechanism of the coating film transfer tool, the ratchet mechanism shown in FIG. 7 has been generally used in order to reduce the rewinding amount of the transfer tape as much as possible. FIG. 7 shows a coating film transfer tool having a conventional reverse rotation prevention mechanism. FIG. 7A is a front view of a coating film transfer tool having a conventional reverse rotation prevention mechanism with the upper case removed. 7 (b) is a sectional view taken along the line YY of FIG. 7 (a). FIG. 7 (c) is a diagram showing a lower case of the conventional coating film transfer tool and ratchet gears provided in the lower case, and FIG. 7 (d) is a winding core and winding of the conventional coating film transfer tool. It is a figure which shows the reverse rotation prevention claw provided in the core. However, FIG. 7B shows a state in which the upper case is attached.

ラチェット機構は、円周上に連続して設けられた方向性を有するラチェット歯車５Ｃと、ラチェット歯車５Ｃの個々の歯と噛み合う逆転防止ツメ３Ｂで構成されるものである。逆転防止ツメ３Ｂは弾性片の先端に設けられ、弾性片の弾性力によってラチェット歯車５Ｃに押し当てられる。図７に示すように、逆転防止ツメ３Ｂの設けられた巻取コア３が、通常の塗膜転写時に回転する方向である、正転方向へ回転する場合には、ラチェット歯車５Ｃと逆転防止ツメ３Ｂは、逆転防止ツメ３Ｂが先端に設けられた弾性片が弾性変形することにより、逆転防止ツメ３Ｂがラチェット歯車５Ｃの斜面を滑って、ラチェット歯車５Ｃを乗り越えることができる形状となっている。一方、巻取コア３が逆転する場合には、ラチェット歯車５Ｃと逆転防止ツメ３Ｂは、それぞれの接触面を、相手方の接触面に対して対面方向へ押し合う形状となっており、逆転防止ツメ３Ｂはラチェット歯車５Ｃを乗り越えることができない。 The ratchet mechanism is composed of a ratchet gear 5C having a directionality continuously provided on the circumference and a reverse rotation prevention claw 3B that meshes with the individual teeth of the ratchet gear 5C. The reverse rotation prevention claw 3B is provided at the tip of the elastic piece and is pressed against the ratchet gear 5C by the elastic force of the elastic piece. As shown in FIG. 7, when the take-up core 3 provided with the reverse rotation prevention claw 3B rotates in the normal rotation direction, which is the direction of rotation during normal coating film transfer, the ratchet gear 5C and the reverse rotation prevention claw The shape of the 3B is such that the elastic piece provided at the tip of the reverse rotation prevention claw 3B is elastically deformed so that the reverse rotation prevention claw 3B can slide on the slope of the ratchet gear 5C and get over the ratchet gear 5C. On the other hand, when the take-up core 3 reverses, the ratchet gear 5C and the reverse rotation prevention claw 3B have a shape in which their respective contact surfaces are pressed against the contact surface of the other party in the facing direction, and the reverse rotation prevention claws have a shape. 3B cannot get over the ratchet gear 5C.

ラチェット機構では、このようにラチェット機構を設けた回転体が逆転しようとすると、すぐにラチェット歯車と逆転防止ツメが係合して逆転が防止される。また、ラチェット歯車の歯車間隔を調整することにより、ラチェット歯車の逆転量を容易に小さくすることができる。このため、ラチェット機構を塗膜転写具の逆転防止機構として採用することにより、転写テープの巻き戻し量を小さくすることができる。 In the ratchet mechanism, when the rotating body provided with the ratchet mechanism tries to reverse the rotation, the ratchet gear and the reverse rotation prevention claw are immediately engaged to prevent the reverse rotation. Further, by adjusting the gear spacing of the ratchet gear, the reversal amount of the ratchet gear can be easily reduced. Therefore, by adopting the ratchet mechanism as the reverse rotation prevention mechanism of the coating film transfer tool, the rewinding amount of the transfer tape can be reduced.

しかしながら、ラチェット機構を塗膜転写具の逆転防止機構として採用すると、正転時にラチェット音が発生するという問題がある。上記のように、巻取コア３の正転時には、逆転防止ツメがラチェット歯車の個々の歯を乗り越えることによって、巻取コア３が回転する。このとき、逆転防止ツメは弾性片の弾性力により、ラチェット歯車に押し当てられているので、逆転防止ツメがラチェット歯車を乗り越えるたびに、逆転防止ツメはラチェット歯車に打ちつけられる。このため、ラチェット機構を逆転防止機構として使用した塗膜転写具では、塗膜転写時に常に逆転防止機構から音、所謂ラチェット音が発生する。 However, when the ratchet mechanism is adopted as the reverse rotation prevention mechanism of the coating film transfer tool, there is a problem that a ratchet sound is generated at the time of normal rotation. As described above, when the take-up core 3 rotates in the normal direction, the take-up core 3 rotates by the reverse rotation prevention claws overcoming the individual teeth of the ratchet gear. At this time, since the reverse rotation prevention claw is pressed against the ratchet gear by the elastic force of the elastic piece, the reverse rotation prevention claw is struck against the ratchet gear every time the reverse rotation prevention claw gets over the ratchet gear. Therefore, in a coating film transfer tool using the ratchet mechanism as a reverse rotation prevention mechanism, a sound, a so-called ratchet sound, is always generated from the reverse rotation prevention mechanism at the time of coating film transfer.

そこで、このようなラチェット音を対策した塗膜転写具が特許文献１などで提案されている。特許文献１では、ラチェット音の低減を課題として、供給リールの一方に配置された第１枠体部材の内面に、リールの回転軸を中心として環状にラチェット歯が形成された環状突起を設け、第１枠体部材よりもリール側に、リールとともに回転し、リールの回転軸を中心とした周方向に延びるアームの先端に、リールが逆転した場合にラチェット歯と噛み合ってリールの逆転を防止するラチェット爪を有するラチェット爪保持体と、ラチェット爪保持体よりもリール側に、リールとともに回転するラチェットアーム押さえ部を備え、ラチェットアーム押さえ部と第１枠体部材により、該アームにおけるラチェット爪保持体の厚さ方向の移動が制限されている塗膜転写具が提案されている。 Therefore, a coating film transfer tool that copes with such ratchet noise has been proposed in Patent Document 1 and the like. In Patent Document 1, in order to reduce ratchet noise, an annular protrusion having ratchet teeth formed in an annular shape around the rotation axis of the reel is provided on the inner surface of the first frame member arranged on one side of the supply reel. The tip of the arm that rotates with the reel on the reel side of the first frame member and extends in the circumferential direction around the rotation axis of the reel meshes with the ratchet teeth when the reel reverses to prevent the reel from reversing. A ratchet claw holder having a ratchet claw and a ratchet arm holding portion that rotates together with the reel are provided on the reel side of the ratchet claw holding body. A coating transfer tool has been proposed in which the movement of the ratchet in the thickness direction is restricted.

特許文献２では、ギア歯形状を複雑化する必要がなく、ギアの製造が容易な逆転防止機構を備える塗膜転写具の提供を目的として、供給ボビン駆動軸、巻取ボビン駆動軸及び回転連結機構による回転系と連結するロールギアと、ロールギア周りの所定範囲を移動可能に配置されてロールギアと歯合する移動ギアと、ロールギアの逆転方向側に対応して配置されて移動ギアと係止可能な係止突起を有する塗膜転写具が提案されている。 In Patent Document 2, a supply bobbin drive shaft, a take-up bobbin drive shaft, and a rotary connection are provided for the purpose of providing a coating transfer tool provided with a reverse rotation prevention mechanism that does not require complicated gear tooth shape and facilitates gear manufacturing. A roll gear connected to a rotation system by a mechanism, a moving gear that is movably arranged around a predetermined range and meshes with the roll gear, and a moving gear that is arranged corresponding to the reverse direction side of the roll gear and can be locked with the moving gear. A coating transfer tool having a locking projection has been proposed.

また、特許文献３では、ケースおよび供給ギアの形状を単純化するとともに、使用時における音の発生を防止することを課題として、支軸に環装させた圧縮コイルスプリングの上端を押えボタンに係止し、下端をスプリング受けに係止させ、圧縮コイルスプリングの付勢力によりスプリング受けの下面を供給ギアの筒状ボスの上面に圧接させて、供給ギアを逆回転させようとする力が生じた場合に、圧縮コイルスプリングが支軸に巻き締められて、供給ギアの逆回転を防止する塗膜転写具が提案されている。 Further, in Patent Document 3, the upper end of the compression coil spring mounted on the support shaft is engaged with the presser button, with the object of simplifying the shapes of the case and the supply gear and preventing the generation of sound during use. It stopped, the lower end was locked to the spring receiver, and the lower surface of the spring receiver was pressed against the upper surface of the cylindrical boss of the supply gear by the urging force of the compression coil spring, and a force was generated to rotate the supply gear in the reverse direction. In some cases, a coating transfer tool has been proposed in which a compression coil spring is wound around a support shaft to prevent reverse rotation of the supply gear.

特許文献４では、塗膜転写具の使用時の逆転防止機構音の発生を防ぐことを課題として、ケース内側面に形成したラチェットの円周方向で隣り合うラチェット歯の間に貫通した開口を形成し、供給リールに一体に形成した係止爪はラチェット歯を乗り越えて復帰するときに、アームの弾性により静止位置を越えた位置まで移動するが、係止爪の先端部が開口に入る塗膜転写具が提案されている。 In Patent Document 4, an opening penetrating between adjacent ratchet teeth in the circumferential direction of the ratchet formed on the inner surface of the case is formed with an object of preventing the generation of a reverse rotation prevention mechanism sound when the coating film transfer tool is used. However, when the locking claw integrally formed with the supply reel gets over the ratchet teeth and returns, it moves to a position beyond the stationary position due to the elasticity of the arm, but the tip of the locking claw enters the opening. Transfer tools have been proposed.

しかしながら、特許文献１の塗膜転写具では、第１枠体部材、リールとともに回転しアームの先端にリールの逆転を防止するラチェット爪を有するラチェット爪保持体、リールとともに回転するラチェットアーム押さえ部などの多くの追加部品を要するとともに、構造が複雑なものとなっていた。特許文献２の塗膜転写具では、移動ギアが所定範囲を移動することによって、逆転防止機構が作用する構造となっており、転写テープの巻き戻り量を非常に小さくすることが困難であった。引用文献３の塗膜転写具でも、供給ギアの逆回転が開始してから、圧縮コイルスプリングが支軸に巻き締められるまでの間、供給ギアが逆回転するため、転写テープの巻き戻り量を非常に小さくすることが困難であった。また、特許文献４の塗膜転写具では、係止爪の先端部が開口に入って、係止爪とラチェット歯が接触しないようになっているので、係止爪はラチェット歯間に、所謂“がた”のある状態で入る。このため、係止爪の先端部が開口に入った状態から、さらに係止爪は移動可能であり、転写テープの巻き戻り量を非常に小さくすることが困難であった。 However, in the coating film transfer tool of Patent Document 1, a first frame member, a ratchet claw holder having a ratchet claw at the tip of the arm that rotates together with the reel and prevents the reel from reversing, a ratchet arm holding portion that rotates with the reel, and the like. It required many additional parts and the structure was complicated. The coating film transfer tool of Patent Document 2 has a structure in which a reverse rotation prevention mechanism acts by moving a moving gear within a predetermined range, and it is difficult to make the rewinding amount of the transfer tape extremely small. .. Even in the coating film transfer tool of Reference 3, the supply gear rotates in the reverse direction from the start of the reverse rotation of the supply gear until the compression coil spring is wound around the support shaft, so that the amount of rewinding of the transfer tape is increased. It was difficult to make it very small. Further, in the coating film transfer tool of Patent Document 4, the tip of the locking claw enters the opening so that the locking claw and the ratchet tooth do not come into contact with each other. Therefore, the locking claw is placed between the ratchet teeth, so-called. Enter with "ratchet". Therefore, the locking claw can be further moved from the state where the tip of the locking claw is in the opening, and it is difficult to reduce the rewinding amount of the transfer tape very much.

逆転防止機構を、巻出コア又は繰出コアの外周に連続して設けられたラチェット歯車、ラチェット歯車と係合して繰出コアの転写テープを繰出す方向の反対方向への回転（以下、逆転と言う）、又は巻取コアが基材テープを巻取る方向の反対方向への回転（以下、逆転と言う）を防止する逆転防止ツメを有する回動部材、及び自己弾性力によって繰出コア又は巻取コアの外周部に圧着され、繰出コア又は巻取コアとともに回転し、繰出コア又は巻取コアが逆転すると逆転防止ツメがラチェット歯車に係合する方向に回動部材を押圧して回動させる弾性部材で構成にした。このような構成とすることにより、繰出コアの転写テープを繰出す方向へ回転（以下、正転と言う）、又は巻取コアが基材テープを巻取る方向へ回転（以下、正転と言う）する場合には、逆転防止ツメはラチェット歯車に押圧されない。このため、繰出コア又は巻取コアの正転時には、逆転防止ツメはラチェット歯車から離れているか、或いは、ラチェット歯車に接触するとしても、逆転防止ツメがラチェット歯車に対して加える圧力は回動部材のわずかな自重のみとなる。このため、本発明の塗膜転写具では巻取コア又は繰出コアが正転する場合には逆転防止ツメがラチェット歯車を強く打ち付けることがなく、塗膜を転写する場合の逆転防止機構によるラチェット音を防止することができる。したがって、本発明の塗膜転写具では、コアの外周に連続して設けられたラチェット歯車、回動部材、弾性部材の３点のみで構成される簡単な構造で、確実に逆転防止機構による音が発生しない塗膜転写具を提供することができる。また、本発明の逆転防止機構では、巻取コア、又は繰出コアが正転する際の弾性部材の回動量を規制する停止部などを設けることなどにより、簡単に弾性部材の回動量を規制できるので、巻取コア又は繰出コアの正転時にも、逆転防止ツメとラチェット歯車を近接した状態とすることができる。このため、本発明の逆転防止機構では、巻取コア又は繰出コアの逆転時に、弾性部材が回動部材を回動させて、すぐに回動部材の逆転防止ツメがラチェット歯車に係合することができるので、転写テープの巻き戻り量も非常に小さくすることもできる。 The reverse rotation prevention mechanism is engaged with the ratchet gears and ratchet gears continuously provided on the outer periphery of the unwinding core or the feeding core, and the transfer tape of the feeding core is rotated in the direction opposite to the feeding direction (hereinafter referred to as reverse rotation). A rotating member with a reverse rotation prevention claw that prevents the winding core from rotating in the direction opposite to the direction in which the base tape is wound (hereinafter referred to as reverse rotation), and a feeding core or winding by self-elastic force. Elasticity that is crimped to the outer periphery of the core and rotates together with the feeding core or winding core, and when the feeding core or winding core reverses, the reverse rotation prevention claw presses the rotating member in the direction of engaging with the ratchet gear to rotate it. It was made up of members. With such a configuration, the transfer core of the feeding core rotates in the direction of feeding (hereinafter referred to as normal rotation), or the winding core rotates in the direction of winding the base tape (hereinafter referred to as normal rotation). ), The reverse rotation prevention claw is not pressed by the ratchet gear. Therefore, when the feeding core or the winding core rotates in the normal direction, the reverse rotation prevention claw is separated from the ratchet gear, or even if it comes into contact with the ratchet gear, the pressure applied to the ratchet gear by the reverse rotation prevention claw is the rotating member. Only a small amount of its own weight. Therefore, in the coating film transfer tool of the present invention, when the take-up core or the feeding core rotates in the normal direction, the reverse rotation prevention claw does not strongly hit the ratchet gear, and the ratchet sound due to the reverse rotation prevention mechanism when transferring the coating film. Can be prevented. Therefore, the coating film transfer tool of the present invention has a simple structure consisting of only three points, a ratchet gear, a rotating member, and an elastic member, which are continuously provided on the outer periphery of the core, and the sound is surely generated by the reverse rotation prevention mechanism. It is possible to provide a coating film transfer tool that does not generate. Further, in the reverse rotation prevention mechanism of the present invention, the rotation amount of the elastic member can be easily regulated by providing a stop portion for regulating the rotation amount of the elastic member when the take-up core or the feeding core rotates in the normal direction. Therefore, even when the take-up core or the feeding core rotates in the normal direction, the reverse rotation prevention claw and the ratchet gear can be kept close to each other. Therefore, in the reverse rotation prevention mechanism of the present invention, when the winding core or the feeding core is reversed, the elastic member rotates the rotating member, and the reverse rotation prevention claw of the rotating member immediately engages with the ratchet gear. Therefore, the amount of rewinding of the transfer tape can be made very small.

FIG. 1A is a front view with the upper case removed. FIG. 1 (b) is a view taken along the line X of FIG. 1 (a). FIG. 1 (c) is a sectional view taken along the line YY of FIG. 1 (b). FIG. 1D is a bottom view of the coating film transfer tool A. Further, FIG. 1 (e) is an enlarged perspective view showing details of a contact portion between the rotating member 1 and the elastic member 8. However, FIG. 1B shows a state in which the upper case is attached.

塗膜転写具Ａは、下ケース５、上ケース６、塗膜を基材テープＳ上に塗工した転写テ－プＴ、転写テープＴを繰出コア２に巻き回した供給リール、転写テープＴに塗工された塗膜を紙等の被転写体の被転写面に転写するために下ケース５と上ケース６で構成される開口部より突出した転写ヘッド４、塗膜を転写した後の基材テ－プＳを巻取コア３に巻き取った巻取リール、繰出コア２と巻取コア３に設けられたプーリーに掛け回され、繰出コア２の回転を巻取コア３に伝えるベルト７、回動部材１、及び弾性部材８で構成されるものである。 The coating film transfer tool A includes a lower case 5, an upper case 6, a transfer tape T in which a coating film is applied on a base material tape S, a supply reel in which a transfer tape T is wound around a feeding core 2, and a transfer tape T. The transfer head 4 protruding from the opening composed of the lower case 5 and the upper case 6 in order to transfer the coating film applied to the transfer surface to the transfer surface of the transfer body such as paper, after the coating film is transferred. A belt in which the base material tape S is wound around a take-up reel, a take-up core 2 and a pulley provided on the take-up core 3 to transmit the rotation of the take-out core 2 to the take-up core 3. It is composed of 7, a rotating member 1, and an elastic member 8.

塗膜転写具Ａでは、繰出コア２の回転を巻取コア３に伝える伝達方法としてベルト７を使用しているが、ギア等による伝達も可能であり、特に制限はない。また、塗膜転写具Ａでは、繰り出し側と巻き取り側の周速差を吸収するスリップ機構もベルト７と、繰出コア２に設けられたプーリーと巻取コア３に設けられたプーリー間のスベリを利用しているが、スリップリング、コイルスプリング、樹脂バネ等によるスベリ機構も利用可能であり、特にその方法を制限するものではない。 In the coating film transfer tool A, the belt 7 is used as a transmission method for transmitting the rotation of the feeding core 2 to the winding core 3, but transmission by a gear or the like is also possible, and there is no particular limitation. Further, in the coating film transfer tool A, the slip mechanism for absorbing the difference in peripheral speed between the feeding side and the winding side is also a slip mechanism between the belt 7 and the pulley provided in the feeding core 2 and the pulley provided in the winding core 3. However, a slip mechanism using a slip ring, a coil spring, a resin spring, or the like can also be used, and the method is not particularly limited.

塗膜転写具Ａでは、転写ヘッド４の先端部の転写押圧部４Ａで転写テープＴを、紙などの被転写面に押圧しつつ、塗膜転写具Ａを移動させると、転写テープＴから塗膜が被転写面に転写され、転写テープＴが繰出コア２から繰り出される。繰出コア２から転写テープＴが繰り出されることによって、繰出コア２が回転すると繰出コア２のプーリーに掛けまわされたベルト７もプーリーの回転に伴って移動する。ベルト７が移動することによって、繰出コア２の回転が巻取コア３に伝えられ、巻取コア３が回転する。プーリーによって伝えられた回転によって、転写ヘッド４で塗膜が転写された残りの基材テープＳを巻取コア３が巻き取って、転写テープＴが弛むことなく走行する。塗膜転写具Ａでは、巻取コア３が巻き取る基材テープＳの長さが、繰出コア２から繰り出される転写テープＴよりも長くなるように、繰出コアと巻出コアの回転比率が設定されているので、転写テープが弛むことがない。また、基材テープＳの巻き取り長さと転写テープＴの繰り出し長さの差は、巻取コア３のプーリーとベルト７が滑ることによって吸収されるので、転写テープＴが引っ張られて切れることもない。 In the coating film transfer tool A, when the coating film transfer tool A is moved while pressing the transfer tape T against the surface to be transferred such as paper by the transfer pressing portion 4A at the tip of the transfer head 4, the coating film transfer tool A is coated from the transfer tape T. The film is transferred to the surface to be transferred, and the transfer tape T is fed from the feeding core 2. By feeding out the transfer tape T from the feeding core 2, when the feeding core 2 rotates, the belt 7 hung on the pulley of the feeding core 2 also moves with the rotation of the pulley. By moving the belt 7, the rotation of the feeding core 2 is transmitted to the winding core 3, and the winding core 3 rotates. Due to the rotation transmitted by the pulley, the winding core 3 winds up the remaining base material tape S on which the coating film is transferred by the transfer head 4, and the transfer tape T runs without loosening. In the coating film transfer tool A, the rotation ratio of the unwinding core and the unwinding core is set so that the length of the base tape S wound by the winding core 3 is longer than that of the transfer tape T unwound from the feeding core 2. Therefore, the transfer tape does not loosen. Further, since the difference between the winding length of the base tape S and the feeding length of the transfer tape T is absorbed by the sliding of the pulley of the winding core 3 and the belt 7, the transfer tape T may be pulled and cut. do not have.

図２に塗膜転写具Ａの逆転防止機構を示す。塗膜転写具Ａでは逆転防止機構を巻取コア３に設ける。図２（ａ）と図２（ｂ）は、図１（ｂ）のＹ－Ｙ断面図であり、塗膜転写具Ａの逆転防止機構の詳細を示す図である。図２（ａ）は塗膜転写具Ａの巻取コア３が正転している状態、即ち、塗膜転写具Ａで塗膜を転写した残りの基材テープを巻取コア３が巻き取っている状態を示す図であり、図２（ｂ）は塗膜転写具Ａの巻取コア３が逆転している状態、例えば、塗膜転写具Ａの転写ヘッド４で転写テープＴを被転写体に押圧した状態で、転写ヘッド４を塗膜転写方向と逆方向に移動させて、巻取コア３から基材テープが引き出されることによって、巻取コア３が基材テープを巻き取る方向とは反対方向に回転した状態を示す図である。 FIG. 2 shows the reverse rotation prevention mechanism of the coating film transfer tool A. In the coating film transfer tool A, a reverse rotation prevention mechanism is provided in the take-up core 3. 2A and 2B are cross-sectional views taken along the line YY of FIG. 1B, showing details of the reverse rotation prevention mechanism of the coating film transfer tool A. FIG. 2A shows a state in which the winding core 3 of the coating film transfer tool A is rotating in the normal direction, that is, the winding core 3 winds up the remaining base material tape on which the coating film is transferred by the coating film transfer tool A. 2 (b) shows a state in which the winding core 3 of the coating film transfer tool A is reversed, for example, the transfer tape T is transferred by the transfer head 4 of the coating film transfer tool A. While pressed against the body, the transfer head 4 is moved in the direction opposite to the coating film transfer direction, and the base tape is pulled out from the take-up core 3, so that the take-up core 3 winds up the base tape. Is a figure showing a state of being rotated in the opposite direction.

図２（ａ）（ｂ）に示すように、塗膜転写具Ａの逆転防止機構は巻取コア３に一体に設けられたラチェット歯車３Ａ、回動部材１、弾性部材８、及び下ケース５に設けられたストッパ（停止部）５Ａで構成されている。回動部材１はラチェット歯車３Ａと係合する逆転防止ツメ１Ａ、及び下ケース５に設けられた支軸５Ｂに回動可能に軸支される軸受け部１Ｂを有している。弾性部材８は巻取コア３の外周部に圧着される圧着部８Ａと回動部材１を押圧して移動させる押圧片８Ｂを有している。塗膜転写具Ａでは、回動部材１の軸受け部１Ｂを回動可能に軸支する支軸５Ｂを、下ケース５のみに設けたが、回動部材１は必ずしも下ケース５に設けた支軸５Ｂのみで軸支する必要はない。回動部材がスムースに回動して逆転防止機構が正常に動作できるのであれば、回動部材１は下ケース５及び／又は上ケース６に設けた支軸に回動可能に軸支されてもよいし、回動部材１に設けた軸がケース５及び／又は上ケース６に設けた穴に回動可能に軸支されてもよい。また、塗膜転写具Ａでは、ラチェット歯車３Ａを巻取コア３に一体に設けたが、巻取コア３と一体となって回転することができれば、ラチェット歯車３Ａは巻取コア３とは別部品としてもよい。 As shown in FIGS. 2A and 2B, the reverse rotation prevention mechanism of the coating film transfer tool A includes a ratchet gear 3A integrally provided on the winding core 3, a rotating member 1, an elastic member 8, and a lower case 5. It is composed of a stopper (stop portion) 5A provided in the above. The rotating member 1 has a reverse rotation prevention claw 1A that engages with the ratchet gear 3A, and a bearing portion 1B that is rotatably supported by a support shaft 5B provided on the lower case 5. The elastic member 8 has a crimping portion 8A that is crimped to the outer peripheral portion of the winding core 3 and a pressing piece 8B that presses and moves the rotating member 1. In the coating film transfer tool A, a support shaft 5B that rotatably supports the bearing portion 1B of the rotating member 1 is provided only in the lower case 5, but the rotating member 1 is not necessarily provided in the lower case 5. It is not necessary to support the shaft only with the shaft 5B. If the rotating member rotates smoothly and the reverse rotation prevention mechanism can operate normally, the rotating member 1 is rotatably supported by a support shaft provided in the lower case 5 and / or the upper case 6. Alternatively, the shaft provided in the rotating member 1 may be rotatably supported in the holes provided in the case 5 and / or the upper case 6. Further, in the coating film transfer tool A, the ratchet gear 3A is integrally provided with the take-up core 3, but if the ratchet gear 3A can rotate integrally with the take-up core 3, the ratchet gear 3A is separate from the take-up core 3. It may be a part.

塗膜転写具Ａの逆転防止機構では、図２（ｂ）に示すように、巻取コア３が逆転すると、弾性部材８も巻取コア３とともに回転して、弾性部材８の押圧片８Ｂが回動部材１を押圧し、回動部材１の逆転防止ツメ１Ａが、巻取コア３のラチェット歯車３Ａに係合する。逆転防止ツメ１Ａがラチェット歯車３Ａと係合した状態では、図２（ｂ）に示すように、ラチェット歯車３Ａと逆転防止ツメ１Ａの接触する面同士が、相手方の接触面に対して対面方向に押し合う形状となっており、逆転防止ツメ１Ａはラチェット歯車３Ａを乗り越えることができず、巻取コア３の逆転が防止される。 In the reverse rotation prevention mechanism of the coating film transfer tool A, as shown in FIG. 2B, when the winding core 3 is reversed, the elastic member 8 also rotates together with the winding core 3, and the pressing piece 8B of the elastic member 8 is pressed. The rotating member 1 is pressed, and the reverse rotation prevention claw 1A of the rotating member 1 engages with the ratchet gear 3A of the take-up core 3. When the reverse rotation prevention claw 1A is engaged with the ratchet gear 3A, as shown in FIG. 2B, the contact surfaces of the ratchet gear 3A and the reverse rotation prevention claw 1A face each other in the facing direction with respect to the contact surface of the other party. The shape is such that they are pressed against each other, and the reverse rotation prevention claw 1A cannot get over the ratchet gear 3A, so that the reverse rotation of the take-up core 3 is prevented.

一方、図２（ｂ）の状態で、塗膜転写具Ａの転写ヘッド４を被転写面に押圧して、塗膜を転写すると、繰出コア２から転写テープＴが繰り出されることによって、繰出コア２が回転し、繰出コア２の回転がベルト７により巻取コア３に伝えられて、巻取コア３が正転する。巻取コア３が正転すると、弾性部材８も巻取コア３とともに回転して、弾性部材８の押圧片８Ｂが回動部材１を押圧する状態が解除される。押圧片８Ｂの回動部材１への押圧が解除されると同時に、巻取コア３が正転することにより、ラチェット歯車３Ａが正転するので、ラチェット歯車３Ａの斜面が逆転防止ツメ１Ａの斜面を押し上げて、逆転防止ツメ１Ａがラチェット歯車３Ａの外周から遠ざかり、ラチェット歯車３Ａと逆転防止ツメ１Ａの係合が解除されて、塗膜転写具Ａの逆転防止機構は、図２（ａ）の状態となる。 On the other hand, in the state of FIG. 2B, when the transfer head 4 of the coating film transfer tool A is pressed against the surface to be transferred to transfer the coating film, the transfer tape T is fed out from the feed core 2 to feed the feed core. 2 rotates, the rotation of the feeding core 2 is transmitted to the winding core 3 by the belt 7, and the winding core 3 rotates in the normal direction. When the take-up core 3 rotates in the normal direction, the elastic member 8 also rotates together with the take-up core 3, and the state in which the pressing piece 8B of the elastic member 8 presses the rotating member 1 is released. At the same time that the pressing of the pressing piece 8B on the rotating member 1 is released, the take-up core 3 rotates in the normal direction, so that the ratchet gear 3A rotates in the normal direction. Is pushed up, the reverse rotation prevention claw 1A moves away from the outer periphery of the ratchet gear 3A, the engagement between the ratchet gear 3A and the reverse rotation prevention claw 1A is released, and the reverse rotation prevention mechanism of the coating film transfer tool A is shown in FIG. 2A. It becomes a state.

図２（ａ）に示すように、塗膜転写具Ａの逆転防止機構には、弾性部材８が正転した際には押圧片８Ｂと接触して、押圧片８Ｂの回転を停止するストッパ（停止部５Ａ）が設けられている。塗膜転写具Ａではストッパは下ケース５に設けたが、必ずしも下ケースのみに設ける必要はない。ストッパは、下ケース５又は上ケース６のどちらか一方から突出した形状としても良いし、下ケース５と上ケース６の両方の形状を組み合わせた構成としても良い。下ケース５と上ケース６の両方の形状を組み合わせた構成としては、例えばストッパを、下ケース５から突出する円柱と、上ケース６から突出する嵌合ピンで構成し、上ケース６の嵌合ピンを、下ケース５の円柱に設けた嵌合穴に嵌合させた、所謂両持ち構造とすることが好ましい。このような両持ち構造とすることで、ストッパの位置精度が向上できるとともに、ストッパが傾くことを防止できる。 As shown in FIG. 2A, the reverse rotation prevention mechanism of the coating film transfer tool A has a stopper (which stops the rotation of the pressing piece 8B by contacting the pressing piece 8B when the elastic member 8 rotates in the normal direction. A stop portion 5A) is provided. In the coating film transfer tool A, the stopper is provided in the lower case 5, but it is not always necessary to provide the stopper only in the lower case. The stopper may have a shape protruding from either the lower case 5 or the upper case 6, or may have a configuration in which both the shapes of the lower case 5 and the upper case 6 are combined. As a configuration in which both the shapes of the lower case 5 and the upper case 6 are combined, for example, the stopper is composed of a cylinder protruding from the lower case 5 and a fitting pin protruding from the upper case 6, and the upper case 6 is fitted. It is preferable to have a so-called double-sided structure in which the pin is fitted into the fitting hole provided in the cylinder of the lower case 5. By adopting such a double-sided structure, the position accuracy of the stopper can be improved and the stopper can be prevented from tilting.

図２（ａ）に示すように、巻取コア３が正転している状態で、ラチェット歯車３Ａの正転により、ラチェット歯車３Ａの斜面が逆転防止ツメ１Ａの斜面を押し上げて、ラチェット歯車３Ａの外周から遠ざかった回動部材１は、弾性部材８の押圧片８Ｂと接触して、それ以上は巻取コア３（ラチェット歯車３Ａ）から遠ざかれなくなっている。この状態におけるラチェット歯車３Ａの最大外径部を繋いだ円周と、逆転防止ツメ１Ａのラチェット歯車３Ａと係合する形状のうちラチェット歯車３Ａに最も近い位置との最短距離Ｌは、０．５ｍｍ以上１ｍｍ以下であること好ましい。Ｌが０．５ｍｍを下回ると、回動部材１が押圧片８Ｂと接触している状態でも、回動部材１の逆転防止ツメ１Ａがラチェット歯車と接触する恐れがあるので、好ましくない。回動部材１が押圧片８Ｂと接触している状態で、回動部材１の逆転防止ツメ１Ａがラチェット歯車３Ａと接触すると、回動部材１が巻取コア３の摺動抵抗となって、巻取コア３の回転が阻害されることにより、巻取コア３で基材テープが巻き取れなくなる恐れがある。巻取コア３が下ケース５及び／又は上ケース６に回転可能に軸支されている軸支部分のクリアランス、所謂「がた」や、ラチェット歯車の外径の偏芯を考慮すると、前記Ｌは０．５ｍｍ以上が好ましい。一方、Ｌが１ｍｍを超えると、ラチェット歯車３Ａの個々の歯の大きさにもよるが、逆転防止機構の作用が遅れ、転写テープの巻き戻り量が大きくなるおそれがある。 As shown in FIG. 2A, in a state where the take-up core 3 is rotating in the normal direction, the slope of the ratchet gear 3A pushes up the slope of the reverse rotation prevention claw 1A due to the normal rotation of the ratchet gear 3A, and the ratchet gear 3A The rotating member 1 that has moved away from the outer circumference of the wheel comes into contact with the pressing piece 8B of the elastic member 8 and is no longer moved away from the take-up core 3 (ratchet gear 3A). In this state, the shortest distance L between the circumference connecting the maximum outer diameter of the ratchet gear 3A and the position closest to the ratchet gear 3A among the shapes engaged with the ratchet gear 3A of the reverse rotation prevention claw 1A is 0.5 mm. It is preferably 1 mm or less. If L is less than 0.5 mm, the reverse rotation prevention claw 1A of the rotating member 1 may come into contact with the ratchet gear even when the rotating member 1 is in contact with the pressing piece 8B, which is not preferable. When the reversing prevention claw 1A of the rotating member 1 comes into contact with the ratchet gear 3A while the rotating member 1 is in contact with the pressing piece 8B, the rotating member 1 becomes a sliding resistance of the take-up core 3. Since the rotation of the take-up core 3 is hindered, there is a risk that the base tape cannot be taken up by the take-up core 3. Considering the clearance of the shaft support portion in which the take-up core 3 is rotatably supported by the lower case 5 and / or the upper case 6, the so-called “gata”, and the eccentricity of the outer diameter of the ratchet gear, the above L Is preferably 0.5 mm or more. On the other hand, if L exceeds 1 mm, the action of the reverse rotation prevention mechanism may be delayed and the amount of rewinding of the transfer tape may increase, depending on the size of each tooth of the ratchet gear 3A.

塗膜転写具Ａの逆転防止機構では、回動部材１と弾性部材８は連結されておらず、別々に動くことができる。また、巻取コア３が正転している間は、弾性部材８の押圧片８Ｂは回動部材１を押圧していないので、回動部材１は弾性部材８の押圧片８Ｂと接触する位置と、ラチェット歯車３Ａの外周部と接触する位置の間で、自由に回動できる状態となる。したがって、回動部材１に作用する重力が、回動部材１をラチェット歯車３Ａから遠ざける方向に作用する場合には、回動部材１の逆転防止ツメ１Ａはラチェット歯車３Ａと接触しないので、塗膜を転写することによって、巻取コア３が正転しても、逆転防止機構による音、所謂ラチェット音が発生することはない。図２に示すように塗膜転写具Ａでは、図２（ａ）における手前側が重力方向であるため、回動部材１に作用する重力は、回動部材１の逆転防止ツメ１Ａをラチェット歯車３Ａに近づける方向に作用するが、塗膜転写具Ａでは、逆転防止機構による音、所謂ラチェット音は発生しない。塗膜転写具Ａでは、ラチェット歯車３Ａが正転しているとき、逆転防止ツメ１Ａがラチェット歯車にわずかに係合すると、ラチェット歯車３Ａの斜面が逆転防止ツメ１Ａの斜面を押し上げて、逆転防止ツメ１Ａがラチェット歯車３Ａの外周から遠ざかる。ラチェット歯車３Ａから遠ざかった逆転防止ツメ１Ａは再び、自重でラチェット歯車３Ａに近づく。このように、逆転防止ツメ１Ａは、微小な範囲でラチェット歯車３Ａに対して、接近と離脱を繰り返す。逆転防止ツメ１Ａはラチェット歯車３Ａの表面を振動しながら滑るような状態となるが、逆転防止ツメ１Ａがラチェット歯車３Ａを押圧する力は、回動部材１の自重による力のみであり、非常に微小な力であるため、逆転防止ツメ１Ａにより発生する音は、人間には聞き取ることができない。このため、塗膜転写具Ａでは、逆転防止機構による音の発生を防止することができる。 In the reverse rotation prevention mechanism of the coating film transfer tool A, the rotating member 1 and the elastic member 8 are not connected and can move separately. Further, since the pressing piece 8B of the elastic member 8 does not press the rotating member 1 while the winding core 3 is rotating in the normal direction, the rotating member 1 is in contact with the pressing piece 8B of the elastic member 8. And, it is in a state where it can freely rotate between the positions where it comes into contact with the outer peripheral portion of the ratchet gear 3A. Therefore, when the gravity acting on the rotating member 1 acts in the direction of moving the rotating member 1 away from the ratchet gear 3A, the reverse rotation prevention claw 1A of the rotating member 1 does not come into contact with the ratchet gear 3A. By transferring the above, even if the winding core 3 rotates in the normal direction, the sound by the reverse rotation prevention mechanism, that is, the so-called ratchet sound is not generated. As shown in FIG. 2, in the coating film transfer tool A, since the front side in FIG. 2A is in the direction of gravity, the gravity acting on the rotating member 1 causes the reversing prevention claw 1A of the rotating member 1 to be the ratchet gear 3A. However, the coating film transfer tool A does not generate a sound due to the reverse rotation prevention mechanism, that is, a so-called ratchet sound. In the coating film transfer tool A, when the ratchet gear 3A is rotating in the normal direction, when the reverse rotation prevention claw 1A slightly engages with the ratchet gear, the slope of the ratchet gear 3A pushes up the slope of the reverse rotation prevention claw 1A to prevent reverse rotation. The claw 1A moves away from the outer circumference of the ratchet gear 3A. The reverse rotation prevention claw 1A away from the ratchet gear 3A again approaches the ratchet gear 3A by its own weight. In this way, the reverse rotation prevention claw 1A repeatedly approaches and detaches from the ratchet gear 3A in a minute range. The reverse rotation prevention claw 1A is in a state of sliding while vibrating the surface of the ratchet gear 3A, but the force with which the reverse rotation prevention claw 1A presses the ratchet gear 3A is only the force due to the own weight of the rotating member 1, which is very large. Since it is a minute force, the sound generated by the reverse rotation prevention claw 1A cannot be heard by humans. Therefore, in the coating film transfer tool A, it is possible to prevent the generation of sound by the reverse rotation prevention mechanism.

弾性部材８の圧着部８Ａは巻取コア３の外周部に、圧着部８Ａの弾性力によって圧着されているので、巻取コア３が回転すると弾性部材８も巻取コア３と共に回転するが、弾性力はごく弱い力に設定されているので、図２（ａ）に示すように弾性部材８の押圧片８Ｂが、下ケース５に設けられたストッパ（停止部）５Ａに接触して回転することができなくなると、巻取コア３のみが圧着部８Ａと滑りながら回転する。圧着部８Ａが巻取コア３に圧着する好ましい弾性力は、塗膜転写具の転写テープ長、転写テープ幅などにもよるが、一般的な塗膜転写具であれば、トルク値に換算して、１．９６×１０^－４Ｎ・ｍ以上４．９０×１０^－４Ｎ・ｍ以下が好ましい。トルク値が１．９６×１０^－４Ｎ・ｍを下回ると、巻取コアが逆転し始めても、すぐに弾性部材８の押圧片８Ｂが回動部材１を押圧出来ず、逆転防止ツメ１Ａとラチェット歯車３Ａの係合が遅れて、巻取コア３の逆転量が大きくなる恐れがある。一方、トルク値が４．９０×１０^－４Ｎ・ｍを超えると、巻取コア３の正転時に弾性部材８によって巻取コアを回転させるために必要なトルクが大きくなり、使用者が塗膜転写具を使いづらくなる。 Since the crimping portion 8A of the elastic member 8 is crimped to the outer peripheral portion of the winding core 3 by the elastic force of the crimping portion 8A, when the winding core 3 rotates, the elastic member 8 also rotates together with the winding core 3. Since the elastic force is set to a very weak force, as shown in FIG. 2A, the pressing piece 8B of the elastic member 8 comes into contact with the stopper (stop portion) 5A provided in the lower case 5 and rotates. When it becomes impossible, only the take-up core 3 rotates while sliding with the crimping portion 8A. The preferable elastic force that the crimping portion 8A crimps to the take-up core 3 depends on the transfer tape length, transfer tape width, etc. of the coating film transfer tool, but if it is a general coating film transfer tool, it is converted into a torque value. It is preferably 1.96 × 10 ^-4 N ・ m or more and 4.90 × 10 ^-4 N ・ m or less. When the torque value is less than 1.96 × 10 ^-4 N ・ m, even if the take-up core starts to reverse, the pressing piece 8B of the elastic member 8 cannot immediately press the rotating member 1, and the reverse rotation prevention claw 1A is used. The engagement of the ratchet gear 3A may be delayed, and the reversal amount of the take-up core 3 may increase. On the other hand, when the torque value exceeds 4.90 × 10 ^-4 N ・ m, the torque required to rotate the winding core by the elastic member 8 when the winding core 3 rotates in the normal direction increases, and the user applies the coating. It becomes difficult to use the membrane transfer tool.

塗膜転写具Ａの弾性部材８は、コイルスプリングに使用するステンレス鋼線や、ピアノ線などの金属線を曲げて成形したものを、使用することが好ましい。弾性部材８は樹脂を成形したものでも使用可能であるが、圧着部８Ａが巻取コア３に圧着する力の経時安定性を考慮すると、金属線の使用が好ましい。また、図１（ｂ）に示すように、巻取コア３からの弾性部材８の脱落を防止するため、巻取コア３には弾性部材８を装着するための溝が設けられることが、好ましい。 As the elastic member 8 of the coating film transfer tool A, it is preferable to use a stainless steel wire used for a coil spring or a wire formed by bending a metal wire such as a piano wire. Although the elastic member 8 can be made of a molded resin, it is preferable to use a metal wire in consideration of the stability of the force with which the crimping portion 8A crimps to the winding core 3 over time. Further, as shown in FIG. 1 (b), in order to prevent the elastic member 8 from falling off from the take-up core 3, it is preferable that the take-up core 3 is provided with a groove for mounting the elastic member 8. ..

塗膜転写具Ａでは逆転防止機構を巻取コア３側に設けたが、逆転防止機構を繰出コア２側に設けてもよく、巻取コア３と繰出コア２の両方に設けてもよい。巻取コア３と繰出
コア２の両方に逆転防止機構を設けると、転写ヘッド４で引き出す転写テープＴの張力が大きくなって、使用者が塗膜転写具を使いづらくなる他、塗膜の転写不良が発生し易くなるため、逆転防止機構は、繰出コア２側か巻取コア３側のどちらか一方に設けることが好ましい。繰出コア２側に逆転防止機構を設けた場合には、繰出コアが逆転しないために転写テープＴが巻き戻されることを防止できる。巻取コア３側に逆転防止機構を設けた場合には、巻取コアが逆転しないために、転写テープが巻き戻されることが防止でき、また、使用者が間違って、転写ヘッドを被転写面に押圧した状態で、通常の転写方向と反対の方向に塗膜転写具を走行させたとしても、巻取コアから転写後の基材テープＳが引き出されることも防止できる。 In the coating film transfer tool A, the reverse rotation prevention mechanism is provided on the take-up core 3 side, but the reverse rotation prevention mechanism may be provided on the take-out core 2 side, or may be provided on both the take-up core 3 and the take-out core 2. If the reverse rotation prevention mechanism is provided on both the take-up core 3 and the take-out core 2, the tension of the transfer tape T pulled out by the transfer head 4 becomes large, which makes it difficult for the user to use the coating film transfer tool and also transfers the coating film. Since defects are likely to occur, it is preferable to provide the reverse rotation prevention mechanism on either the feeding core 2 side or the winding core 3 side. When the reverse rotation prevention mechanism is provided on the feeding core 2 side, it is possible to prevent the transfer tape T from being rewound because the feeding core does not reverse. When a reverse rotation prevention mechanism is provided on the take-up core 3 side, the take-up core does not reverse, so that the transfer tape can be prevented from being rewound, and the user mistakenly puts the transfer head on the surface to be transferred. Even if the coating film transfer tool is run in a direction opposite to the normal transfer direction while being pressed against, it is possible to prevent the substrate tape S after transfer from being pulled out from the winding core.

図３に、本発明の第２実施形態の塗膜転写具Ｂの逆転防止機構を示す。塗膜転写具Ｂの全体図は省略するが、図２が図１（ｂ）のＹ－Ｙ断面を示すのと同様に、図３も塗膜転写具Ｂの弾性部材８を図１（ｂ）のＹ－Ｙ断面と同じ位置で切り取り、同じ方向から見た断面図である。図３（ａ）は巻取コア３が正転している状態を示す図であり、図３（ｂ）は塗膜転写具Ｂの逆転防止機構が巻取コア３の逆転を防止している状態を示す図である。塗膜転写具Ｂの逆転防止機構以外の構成は、塗膜転写具Ａと同様である。塗膜転写具Ｂの逆転防止機構は、回動部材１の形状が、塗膜転写具Ａとは異なっている。 FIG. 3 shows a reverse rotation prevention mechanism of the coating film transfer tool B according to the second embodiment of the present invention. Although the overall view of the coating film transfer tool B is omitted, FIG. 3 also shows the elastic member 8 of the coating film transfer tool B in FIG. 1 (b), just as FIG. 2 shows the YY cross section of FIG. 1 (b). ) Is cut out at the same position as the YY cross section, and is a cross-sectional view seen from the same direction. FIG. 3A is a diagram showing a state in which the winding core 3 is rotating in the normal direction, and FIG. 3B is a diagram in which the reverse rotation prevention mechanism of the coating film transfer tool B prevents the winding core 3 from rotating in the normal direction. It is a figure which shows the state. The configuration of the coating film transfer tool B other than the reverse rotation prevention mechanism is the same as that of the coating film transfer tool A. The reversal prevention mechanism of the coating film transfer tool B is different in the shape of the rotating member 1 from the coating film transfer tool A.

塗膜転写具Ａでは、弾性部材８の押圧片８Ｂが、回動部材１の逆転防止ツメ１Ａ付近を押圧して、逆転防止ツメ１Ａをラチェット歯車３Ａに係合させる形状であった。これに対して、塗膜転写具Ｂでは、図３に示すように支軸５Ｂから逆転防止ツメ１Ａまでの距離に比べて、支軸５Ｂから押圧片８Ｂが回動部材１を押圧する位置までの距離が短くなるように構成した。このような構成とすることにより、弾性部材８の押圧片８Ｂが回動部材１を押圧する速度よりも、逆転防止ツメ１Ａがラチェット歯車３Ａに係合する速度を早くすることができる。このため、塗膜転写具Ｂでは塗膜転写具Ａに比べて、より確実に巻取コア３の逆転を防止することができる。 In the coating film transfer tool A, the pressing piece 8B of the elastic member 8 presses the vicinity of the reversing prevention claw 1A of the rotating member 1 to engage the reversing prevention claw 1A with the ratchet gear 3A. On the other hand, in the coating film transfer tool B, as shown in FIG. 3, the distance from the support shaft 5B to the position where the pressing piece 8B presses the rotating member 1 is compared with the distance from the support shaft 5B to the reverse rotation prevention claw 1A. It was configured to shorten the distance of. With such a configuration, the speed at which the reverse rotation prevention claw 1A engages with the ratchet gear 3A can be made faster than the speed at which the pressing piece 8B of the elastic member 8 presses the rotating member 1. Therefore, the coating film transfer tool B can more reliably prevent the reversal of the take-up core 3 than the coating film transfer tool A.

図４に、本発明の第３実施形態の塗膜転写具Ｃの逆転防止機構を示す。塗膜転写具Ｃの全体図は省略するが、図２が図１（ｂ）のＹ－Ｙ断面として弾性部材８の中央部分の断面を切り取っていたのに対して、図４は塗膜転写具Ｃの弾性部材８のラチェット歯車３Ａ側と反対側の端面で切り取り、図１（ｂ）のＹ－Ｙ断面と同じ方向から見た断面図である。図４（ａ）は巻取コア３が正転している状態を示す図であり、図４（ｂ）は塗膜転写具Ｃの逆転防止機構が巻取コア３の逆転を防止している状態を示す図である。図４（ｃ）は、回動部材１と弾性部材８の連結部の詳細を示す斜視図である。塗膜転写具Ｃの逆転防止機構以外の構成は、塗膜転写具Ａ、Ｂと同様である。塗膜転写具Ｃの逆転防止機構は、回動部材１と弾性部材８が連結されている点が塗膜転写具Ａ、Ｂとは異なっている。塗膜転写具Ｃでは、弾性部材８の押圧片８Ｂの先端部分が図４（ａ）、（ｂ）の下方向（ラチェット歯車が設けられた平面に対して垂直方向）に、ほぼ直角に折り曲げられた形状の係合片８Ｃが設けられており、この係合片８Ｃが回動部材１に設けられた長穴状の案内穴１Ｃ内に挿入されており、係合片８Ｃは案内穴１Ｃ内を移動可能になっている。このように、係合片８Ｃが案内穴１Ｃ内に挿入されることによって、回動部材１と弾性部材８が連結されているので、回動部材１と弾性部材８は連動して動くようになっている。塗膜転写具Ｃでは、巻取コア３が正転している間は、弾性部材８の係合片８Ｃは巻取コア３とともに、図４において時計回りに回転して、図４（ａ）の状態になる。図４（ａ）の状態になると係合片８Ｃが案内穴１Ｃの右端に接触して、これ以上移動することができないので、巻取コア３が正転している間、弾性部材８と回動部材１は図４（ａ）の状態で維持される。このように、塗膜転写具Ｃでは、巻取コア３が正転している間は、回動部材１の逆転防止ツメ１Ａがラチェット歯車３Ａに全く接触することがないので、塗膜転写具Ａ、Ｂよりもさらに確実に、逆転防止機構による音の発生を防止することができる。図４（ａ）の状態におけるラチェット歯車３Ａの最大外径部を繋いだ円周と、逆転防止ツメ１Ａのラチェット歯車３Ａに最も近い位置との最短距離Ｌは、０．５ｍｍ以上１ｍｍ以下であること好ましいことは、塗膜転写具Ｃでも同様である。塗膜転写具Ｃでは、案内穴１Ｃの寸法を調節することにより、Ｌを０．５ｍｍ以上１ｍｍ以下の範囲とすることができる。 FIG. 4 shows a reverse rotation prevention mechanism of the coating film transfer tool C according to the third embodiment of the present invention. Although the overall view of the coating film transfer tool C is omitted, FIG. 2 shows a cross section of the central portion of the elastic member 8 as the YY cross section of FIG. 1 (b), whereas FIG. 4 shows the coating film transfer. It is a cross-sectional view seen from the same direction as the YY cross section of FIG. 1B, cut out at the end face of the elastic member 8 of the tool C on the side opposite to the ratchet gear 3A side. FIG. 4A is a diagram showing a state in which the winding core 3 is rotating in the normal direction, and FIG. 4B is a diagram in which the reverse rotation prevention mechanism of the coating film transfer tool C prevents the winding core 3 from rotating in the normal direction. It is a figure which shows the state. FIG. 4C is a perspective view showing details of the connecting portion between the rotating member 1 and the elastic member 8. The configuration of the coating film transfer tool C other than the reverse rotation prevention mechanism is the same as that of the coating film transfer tools A and B. The reverse rotation prevention mechanism of the coating film transfer tool C is different from the coating film transfer tools A and B in that the rotating member 1 and the elastic member 8 are connected. In the coating film transfer tool C, the tip portion of the pressing piece 8B of the elastic member 8 is bent at a substantially right angle in the downward direction (perpendicular to the plane provided with the ratchet gear) in FIGS. 4A and 4B. An engaging piece 8C having a formed shape is provided, and the engaging piece 8C is inserted into a long hole-shaped guide hole 1C provided in the rotating member 1, and the engaging piece 8C is a guide hole 1C. It is possible to move inside. By inserting the engaging piece 8C into the guide hole 1C in this way, the rotating member 1 and the elastic member 8 are connected, so that the rotating member 1 and the elastic member 8 move in conjunction with each other. It has become. In the coating film transfer tool C, while the winding core 3 is rotating in the normal direction, the engaging piece 8C of the elastic member 8 rotates clockwise together with the winding core 3 in FIG. 4A. It becomes the state of. In the state shown in FIG. 4A, the engaging piece 8C comes into contact with the right end of the guide hole 1C and cannot move any further. Therefore, while the winding core 3 rotates in the normal direction, it rotates with the elastic member 8. The moving member 1 is maintained in the state shown in FIG. 4 (a). As described above, in the coating film transfer tool C, the reverse rotation prevention claw 1A of the rotating member 1 does not come into contact with the ratchet gear 3A at all while the winding core 3 is rotating in the normal direction. It is possible to prevent the generation of sound by the reverse rotation prevention mechanism more reliably than A and B. The shortest distance L between the circumference connecting the maximum outer diameters of the ratchet gear 3A in the state of FIG. 4A and the position closest to the ratchet gear 3A of the reverse rotation prevention claw 1A is 0.5 mm or more and 1 mm or less. The same is true for the coating film transfer tool C. In the coating film transfer tool C, L can be set to a range of 0.5 mm or more and 1 mm or less by adjusting the dimensions of the guide hole 1C.

塗膜転写具Ｃの逆転防止機構では、図４に示すように、巻取コア３が逆転すると、弾性部材８も巻取コア３とともに回転して、弾性部材８の係合片８Ｃが、回動部材１の案内穴１Ｃ内を移動して、図４（ａ）の状態から図４（ｂ）の状態になる。弾性部材８の係合片８Ｃが回動部材１の案内穴１Ｃ内の右端から左端まで移動することにより、回動部材１の逆転防止ツメ１Ａがラチェット歯車３Ａと係合して、ラチェット歯車３Ａはこれ以上逆転することができなくなり、巻取コア３の逆転を防止することができる。塗膜転写具Ｃでは、案内穴１Ｃを回動部材１に設け、案内穴１Ｃ内を移動する係合片８Ｃを弾性部材８に設けたが、案内穴１Ｃに相当するガイド穴を弾性部材８に設け、係合片８Ｃに相当し、前記ガイド穴内を移動するガイド軸を回動部材１に設けてもよい。弾性部材８を樹脂製の樹脂バネとすれば、弾性部材８にガイド穴を設けることができる。 In the reverse rotation prevention mechanism of the coating film transfer tool C, as shown in FIG. 4, when the winding core 3 is reversed, the elastic member 8 also rotates together with the winding core 3, and the engaging piece 8C of the elastic member 8 rotates. It moves in the guide hole 1C of the moving member 1 and changes from the state of FIG. 4A to the state of FIG. 4B. When the engaging piece 8C of the elastic member 8 moves from the right end to the left end in the guide hole 1C of the rotating member 1, the reverse rotation prevention claw 1A of the rotating member 1 engages with the ratchet gear 3A, and the ratchet gear 3A. Can no longer reverse, and can prevent the take-up core 3 from reversing. In the coating film transfer tool C, the guide hole 1C is provided in the rotating member 1, and the engaging piece 8C that moves in the guide hole 1C is provided in the elastic member 8, but the guide hole corresponding to the guide hole 1C is provided in the elastic member 8. A guide shaft corresponding to the engaging piece 8C and moving in the guide hole may be provided in the rotating member 1. If the elastic member 8 is a resin spring made of resin, a guide hole can be provided in the elastic member 8.

図５に、本発明の第４実施形態の塗膜転写具Ｄの逆転防止機構を示す。塗膜転写具Ｄの全体図は省略するが、図２が図１（ｂ）のＹ－Ｙ断面を示すのと同様に、図５も塗膜転写具Ｄの弾性回動部材９の弾性部材８に相当する部分を図１（ｂ）のＹ－Ｙ断面と同じ位置で切り取り、同じ方向から見た断面図である。図５（ａ）は巻取コア３が正転している状態を示す図であり、図５（ｂ）は塗膜転写具Ｄの逆転防止機構が巻取コア３の逆転を防止している状態を示す図である。塗膜転写具Ｄの逆転防止機構以外の構成は、塗膜転写具Ａ、Ｂ、Ｃと同様である。塗膜転写具Ｄの逆転防止機構は、回動部材１と弾性部材８が一体の部材である弾性回動部材９となっている以外は、塗膜転写具Ａ、Ｂ、Ｃと同様である。塗膜転写具Ｄでは、弾性部材８と回動部材１に相当する部品が一体の成形品となっているが、必ずしも一体成形品とする必要はなく、弾性部材に相当する部分を金属で製作し、回動部材に相当する部分を樹脂で製作して、これらの２以上の部品を嵌合や接着で一体としてもよい。 FIG. 5 shows a reverse rotation prevention mechanism of the coating film transfer tool D according to the fourth embodiment of the present invention. Although the overall view of the coating film transfer tool D is omitted, FIG. 5 also shows the elastic member of the elastic rotating member 9 of the coating film transfer tool D, just as FIG. 2 shows the YY cross section of FIG. 1 (b). 8 is a cross-sectional view of a portion corresponding to 8 cut out at the same position as the YY cross section of FIG. 1 (b) and viewed from the same direction. FIG. 5A is a diagram showing a state in which the winding core 3 is rotating in the normal direction, and FIG. 5B is a diagram in which the reverse rotation prevention mechanism of the coating film transfer tool D prevents the winding core 3 from rotating in the normal direction. It is a figure which shows the state. The configuration of the coating film transfer tool D other than the reverse rotation prevention mechanism is the same as that of the coating film transfer tools A, B, and C. The reverse rotation prevention mechanism of the coating film transfer tool D is the same as that of the coating film transfer tools A, B, and C except that the rotating member 1 and the elastic member 8 are an elastic rotating member 9 which is an integral member. .. In the coating film transfer tool D, the elastic member 8 and the component corresponding to the rotating member 1 are integrally molded products, but it is not always necessary to form an integrally molded product, and the portion corresponding to the elastic member is manufactured of metal. Then, the portion corresponding to the rotating member may be made of resin, and these two or more parts may be integrated by fitting or adhering.

塗膜転写具Ｄでも、塗膜転写具Ｂと同様に、下ケース５に設けられ弾性回動部材９における回動部材１に相当する部分を回動可能に保持する支軸５Ｂが設けられており、逆転防止ツメ９Ａが支軸５Ｂを中心として回動可能となっている。また、塗膜転写具Ｄでも弾性回動部材９の弾性部材８に相当する部分には圧着部９Ｄが設けられ、弾性回動部材９は巻取コア３の外周部に圧着部９Ｄの弾性力によって圧着されている。この弾性力により、巻取コア３が回転すると弾性回動部材９も巻取コア３と共に回転するが、弾性力はごく弱い力に設定されているので、ある一定の外力が弾性回動部材９に作用して弾性回動部材９が回転できなくなると、巻取コア３のみが圧着部９Ｄと滑りながら回転することも塗膜転写具Ａ、Ｂ、Ｃと同様である。塗膜転写具Ｄでも、巻取コア３が逆転すると圧着部９Ｄが巻取コア３とともに逆転し、これによって、弾性回動部材９の押圧片９Ｃが回転して、逆転防止ツメ９Ａをラチェット歯車３Ａ方向へ移動させて、逆転防止ツメ９Ａとラチェット歯車３Ａを係合させるのも、塗膜転写具Ｂと同様である。 Similar to the coating film transfer tool B, the coating film transfer tool D is also provided with a support shaft 5B provided in the lower case 5 to rotatably hold a portion of the elastic rotating member 9 corresponding to the rotating member 1. The reverse rotation prevention claw 9A can rotate around the support shaft 5B. Further, even in the coating film transfer tool D, a crimping portion 9D is provided at a portion corresponding to the elastic member 8 of the elastic rotating member 9, and the elastic rotating member 9 has an elastic force of the crimping portion 9D on the outer peripheral portion of the winding core 3. Is crimped by. When the winding core 3 rotates due to this elastic force, the elastic rotating member 9 also rotates together with the winding core 3, but since the elastic force is set to a very weak force, a certain external force is applied to the elastic rotating member 9. Similar to the coating transfer tools A, B, and C, when the elastic rotating member 9 cannot rotate due to the above-mentioned action, only the winding core 3 rotates while sliding with the crimping portion 9D. Even in the coating film transfer tool D, when the winding core 3 is reversed, the crimping portion 9D is reversed together with the winding core 3, whereby the pressing piece 9C of the elastic rotating member 9 is rotated, and the reverse rotation prevention claw 9A is ratcheted. Similar to the coating film transfer tool B, the ratchet gear 3A is engaged with the reverse rotation prevention claw 9A by moving in the 3A direction.

塗膜転写具Ｄの弾性回動部材９では、逆転防止ツメ９Ａの支軸５Ｂに軸支される付近と押圧片９Ｃが、弾性連結部９Ｂで連結されている点が、塗膜転写具Ａ、Ｂ、Ｃと異なる。弾性連結部９Ｂは、押圧片９Ｃと逆転防止ツメ９Ａよりも弾性変形し易くなっている。塗膜転写具Ｄでは、弾性連結部９Ｂの厚みを押圧片９Ｃよりも薄くするとともに、弾性連結部９Ｂの形状が、図５に示す所謂「コの字」の形状などの、限られた面積の中に多くの変形可能な箇所が存在する形状となるようにして、弾性連結部９Ｂを変形し易くしている。このように、塗膜転写具Ｄでは、弾性連結部９Ｂを変形し易くするために、弾性連結部９Ｂの形状を「コの字」の形状としているが、弾性連結部９Ｂの形状は他の部分よりも変形し易く、かつ、図５（ａ）の状態と図５（ｂ）の状態の間で繰り返し変形し続けても、クリープなどにより破損しない形状であれば、任意の形状を採用可能である。また、弾性回動部材９を一体成形品で製作した場合に、逆転防止機構を正常に作動させるために必要な弾性連結部９Ｂの弾性力と、弾性連結部９Ｂに要求される前記耐クリープ性などの耐久性の両方を同時に満足させることが困難であれば、弾性回動部材９の弾性連結部９Ｂのみを金属薄板や金属線で製作し、その他の部分を樹脂で製作して、これらの部品を嵌合や接着で一体としてもよいし、逆転防止ツメ９Ａのみを樹脂で製作し、その他の部分を金属薄板や金属線で製作してもよい。 In the elastic rotating member 9 of the coating film transfer tool D, the point where the pressing piece 9C is connected to the vicinity of the support shaft 5B of the reverse rotation prevention claw 9A by the elastic connecting portion 9B is the point that the coating film transfer tool A is connected. , B, C are different. The elastic connecting portion 9B is more easily elastically deformed than the pressing piece 9C and the reverse rotation prevention claw 9A. In the coating film transfer tool D, the thickness of the elastic connecting portion 9B is made thinner than that of the pressing piece 9C, and the shape of the elastic connecting portion 9B is a limited area such as the so-called “U” shape shown in FIG. The elastic connecting portion 9B is easily deformed by forming a shape in which many deformable portions exist. As described above, in the coating film transfer tool D, the shape of the elastic connecting portion 9B is a "U" shape in order to facilitate the deformation of the elastic connecting portion 9B, but the shape of the elastic connecting portion 9B is different. Any shape can be adopted as long as it is more easily deformed than the portion and is not damaged by creep even if it is repeatedly deformed between the state of FIG. 5 (a) and the state of FIG. 5 (b). Is. Further, when the elastic rotating member 9 is manufactured as an integrally molded product, the elastic force of the elastic connecting portion 9B required to normally operate the reverse rotation prevention mechanism and the creep resistance required for the elastic connecting portion 9B. If it is difficult to satisfy both of the durability at the same time, only the elastic connecting portion 9B of the elastic rotating member 9 is made of a thin metal plate or a metal wire, and the other parts are made of resin. The parts may be integrated by fitting or bonding, or only the reverse rotation prevention claw 9A may be made of resin, and the other parts may be made of a thin metal plate or a metal wire.

塗膜転写具Ｄでは、巻取コア３が正転すると、弾性回動部材９の圧着部９Ｄは巻取コア３とともに時計回りに回転し、押圧片９Ｃも圧着部９Ｄとともに時計回りに回転する。弾性連結部９Ｂも、押圧片９Ｃと連結されているので、押圧片９Ｃが時計回りに回転すると、押圧片９Ｃとともに時計回りに回転し始める。しかしながら、弾性連結部９Ｂは、端部が支軸５Ｂに回転可能に軸支されているため、押圧片９Ｃと同様の回転運動をすることはできず、弾性変形しながら時計回りに回転する。弾性連結部９Ｂの変形量が大きくなると、弾性連結部９Ｂの弾性力により、押圧片９Ｃを引っ張る力が大きくなる。弾性連結部９Ｂが押圧片９Ｃを引っ張る力が大きくなって、圧着部９Ｄが押圧片９Ｃを引っ張る力が釣り合うと、圧着部９Ｄが巻取コア３の外周部と滑って、弾性連結部９Ｂは、その位置で回転を停止する。図５（ａ）はこの状態を示しており、弾性回動部材９の逆転防止ツメ９Ａも弾性連結部９Ｂを介して、押圧片９Ｃに引っ張られて時計回りに回動するので、逆転防止ツメ９Ａはラチェット歯車３Ａと係合しない状態となっている。このため、塗膜転写具Ｄでも塗膜転写具Ａ、Ｂよりもさらに確実に、逆転防止機構による音の発生を防止することができる。図５（ａ）の状態におけるラチェット歯車３Ａの最大外径部を繋いだ円周と、逆転防止ツメ１Ａのラチェット歯車３Ａに最も近い位置との最短距離Ｌは、０．５ｍｍ以上１ｍｍ以下であること好ましいことは、塗膜転写具Ｄでも同様である。塗膜転写具Ｄでは、弾性連結部９Ｂの弾性力を調整することにより、Ｌを０．５ｍｍ以上１ｍｍ以下の範囲とすることができる。 In the coating film transfer tool D, when the winding core 3 rotates in the normal direction, the crimping portion 9D of the elastic rotating member 9 rotates clockwise together with the winding core 3, and the pressing piece 9C also rotates clockwise together with the crimping portion 9D. .. Since the elastic connecting portion 9B is also connected to the pressing piece 9C, when the pressing piece 9C rotates clockwise, it starts to rotate clockwise together with the pressing piece 9C. However, since the end portion of the elastic connecting portion 9B is rotatably supported by the support shaft 5B, the elastic connecting portion 9B cannot perform the same rotational motion as the pressing piece 9C, and rotates clockwise while elastically deforming. When the amount of deformation of the elastic connecting portion 9B becomes large, the force of pulling the pressing piece 9C becomes large due to the elastic force of the elastic connecting portion 9B. When the force of the elastic connecting portion 9B pulling the pressing piece 9C becomes large and the force of the crimping portion 9D pulling the pressing piece 9C is balanced, the crimping portion 9D slides with the outer peripheral portion of the winding core 3 and the elastic connecting portion 9B becomes. , Stops rotation at that position. FIG. 5A shows this state. Since the reverse rotation prevention claw 9A of the elastic rotating member 9 is also pulled by the pressing piece 9C via the elastic connecting portion 9B and rotates clockwise, the reverse rotation prevention claw 9A is shown. 9A is in a state of not engaging with the ratchet gear 3A. Therefore, the coating film transfer tool D can more reliably prevent the generation of sound by the reverse rotation prevention mechanism than the coating film transfer tools A and B. The shortest distance L between the circumference connecting the maximum outer diameters of the ratchet gear 3A in the state of FIG. 5A and the position closest to the ratchet gear 3A of the reverse rotation prevention claw 1A is 0.5 mm or more and 1 mm or less. The same is true for the coating film transfer tool D. In the coating film transfer tool D, L can be set in the range of 0.5 mm or more and 1 mm or less by adjusting the elastic force of the elastic connecting portion 9B.

塗膜転写具Ｄの逆転防止機構では、巻取コア３が逆転すると、図５（ｂ）に示すように、弾性回動部材９も巻取コア３とともに回転して、弾性回動部材９の圧着部９Ｄが反時計回りに回転し、これによって押圧片９Ｃも反時計回りに回転する。押圧片９Ｃが反時計回りに回転すると、弾性連結部９Ｂは回動しつつ、弾性変形が解除されて、図５（ｂ）の状態となる。逆転防止ツメ９Ａが支軸５Ｂに回動可能に軸支されているため、弾性連結部９Ｂの押圧片９Ｃに近い箇所に比べて、逆転防止ツメ９Ａに近い部分の移動できる距離が短くなっており、この移動量の差を吸収するために、正転時と反対に弾性連結部９Ｂの弾性変形が解除される。弾性連結部９Ｂが回動した分だけ、逆転防止ツメ９Ａも回動し、逆転防止ツメ９Ａがラチェット歯車３Ａに係合して、巻取コア３の逆転が防止される。 In the reverse rotation prevention mechanism of the coating film transfer tool D, when the winding core 3 is reversed, the elastic rotating member 9 also rotates together with the winding core 3 as shown in FIG. 5 (b), and the elastic rotating member 9 The crimping portion 9D rotates counterclockwise, whereby the pressing piece 9C also rotates counterclockwise. When the pressing piece 9C rotates counterclockwise, the elastic connecting portion 9B rotates while the elastic deformation is released, and the state shown in FIG. 5B is obtained. Since the reverse rotation prevention claw 9A is rotatably supported by the support shaft 5B, the movable distance of the portion close to the reverse rotation prevention claw 9A is shorter than that of the elastic connecting portion 9B near the pressing piece 9C. In order to absorb this difference in the amount of movement, the elastic deformation of the elastic connecting portion 9B is released as opposed to the case of normal rotation. The reverse rotation prevention claw 9A also rotates by the amount that the elastic connecting portion 9B rotates, and the reverse rotation prevention claw 9A engages with the ratchet gear 3A to prevent the winding core 3 from reversing.
