Description

【０００１】
【産業上の利用分野】
本発明は、文字修正用塗膜、装飾用着色塗膜、接着用粘着膜等の粘着性を有する転写膜を紙等の被転写面に押圧転写させる場合に用いられる膜転写ローラーであって、詳しくは、可撓性を備えた基材の一側面を押圧しながら転動させて、当該基材の他側面に設けられている転写膜を被転写面に転写する転動部を備えている膜転写ローラーに関する。
【０００２】
【従来の技術】
従来、この種の膜転写ローラーとしては、転動部の押圧周面が、回転軸芯方向両端部に亘って平滑な円周面に形成されていて、例えば、特開平６−２８６９２７号公報に示すように、他側面に転写膜が設けられている可撓性を備えた基材が繰り出しコアに巻付けられている場合、この繰り出しコアから引き出された基材の一側面を転動部で押圧しながら転写膜を被転写面に押し付け、そのまま転動部を転写方向下手側に移動して、被転写面に対する転写膜の接着力により基材を繰り出しコアから転写膜と共に転動部側に引き出すとともに、この基材の一側面と転動部の押圧周面との摩擦力で転動部を転動させながら、転写膜を被転写面に転写するように構成したものがある。
【０００３】
【発明が解決しようとする課題】
一般に、この種の膜転写ローラーにより押圧転写される転写膜が設けられた基材の前記他側面には、弱い押圧力で転動部を転動させても転写膜を被転写面に容易に押圧転写できるようにするために、シリコーン樹脂等からなる離型剤を塗布してあり、基材に対する転写膜の剥離性を向上させてある。
【０００４】
従って、転写膜を被転写面に転写する際、転動部で押圧される部位の基材部分に転写膜が存在しない状態、例えば、前回の転写膜の転写時に、転動部で押圧される部位よりも上手側の転写膜が剥離されてしまった状態では、図１２に示すように、被転写面Ａと基材１の他側面とが直接接当することとなるが、基材１の他側面には前述の如く離型剤が塗布してあるために摩擦係数が低く、特に、被転写面Ａが紙の様に比較的滑り易い素材のものから構成されている場合は、基材１が被転写面Ａに対してスリップし易くなるので、転動部０３を転写方向下手側に移動させても、転写膜を基材１と共に転動部０３で押圧される部位まで引き出し難くなる。そのため、転写膜の被転写面Ａに対する転写不良を発生する問題があった。
本発明は、上記実情に鑑みてなされたものであって、転写ローラーの合理的な改良により、使用開始時に、転動部で押圧される部位の基材部分に転写膜が存在しないときでも、従来に比べて転写膜の転写不良が発生することを抑制することができる転写ローラーを提供することを目的とする。
【０００５】
【課題を解決するための手段】
上記目的を達成するための本発明の第１の特徴構成は、可撓性を備えた基材の一側面を押圧しながら転動させて、当該基材の他側面に設けられている転写膜を被転写面に転写する転動部を備えている膜転写ローラーであって、前記転動部の少なくとも回転軸芯方向両端部の一端側に、当該転動部の押圧周面から径方向外方に向かって前記基材の厚みと前記転写膜の厚みの和よりも大に突出して、被転写面との接当に伴って前記転動部に回転力を付与する突出部を、前記転動部の押圧周面の円周方向に沿って連続的又は断続的に設けてあるとともに、前記突出部が、前記転写膜と前記被転写面との押圧接当を許容する状態まで弾性変形自在に構成されている点にある。
本発明の第２の特徴構成は、前記突出部が前記転動部の回転軸芯方向両端部に設けられているとともに、両突出部の相対向面が、前記基材の前記転動部の回転軸芯方向への移動を規制する規制面に構成されている点にある。
【０００６】
【作用】
本発明の第１特徴構成による場合は、突出部が転動部の押圧周面の円周方向に沿って連続的又は断続的に設けられているので、転動部で押圧される部位の基材部分に転写膜が存在しないときでも、基材の一側面を転動部で被転写面側に押圧して転写方向下手に移動させると、突出部が被転写面に接当しながら回転し、転動部に回転力が付与されて転動部が転動するとともに、この転動状態の転動部の押圧周面と基材の一側面との摩擦力で、転写膜が存在しない基材部分が転動部の回転方向下手側に送り出されるので、転動部で押圧される部位の基材部分と被転写面との間でスリップが発生することを抑制することができ、もって、転動部で押圧される部位の基材部分に転写膜を引き出すことができ、また、転写膜が被転写面に押圧転写されている状態でも突出部と被転写面とが接当するので、この状態でも転動部を基材を介することなく直接転動させることができる。
【０００７】
しかも、突出部の突出代を基材の厚みと転写膜の厚みの和より大に構成することにより、突出部の突出代を基材の厚み以上で、かつ、基材の厚みと転写膜の厚みの和以下に構成する場合に比べて、突出部の最大突出代の寸法精度をラフにでき、もって、突出部の製作の容易化を図ることができるとともに、基材及び転写膜を、転動部の押圧周面と突出部の先端との間の突出代内に位置させることができる。
本発明の第２特徴構成による場合は、基材が蛇行しても、転動部では基材の該転動部の回転軸芯方向への移動が規制されているので、基材が転動部の押圧周面から転動部の回転軸芯方向にはみ出すことがない又は殆どない。
【０００８】
【発明の効果】
本発明の第１特徴構成では、使用開始時に、転動部で押圧される部位の基材部分に転写膜が存在しないときでも、転動部の転動により当該基材部分を転動部の回転方向下手側に送り出し、回転方向上手側の転写膜が存在する基材部分を転動部に移動させることができるので、従来に比べて転写膜の転写不良が発生することを抑制することができるとともに、転写膜が欠落していない通常の膜転写時においても、前記転動部の押圧周面と基材との間での摩擦力と、突出部と被転写面との間での摩擦力によって、転動部が基材と一体的に回動するから、転動部の押圧周面と基材との間での摩擦力のみによって転動部を回転させる場合に比して、基材の転動部からの送り出し移動をスムーズに行うことができる。
【０００９】
しかも、突出部が弾性変形しない限り転写膜は当該被転写部分に押圧接当されることがないので、転動部で押圧される部位の基材部分の転写膜が、取扱いの不注意で被転写面の被転写部分等に転写されることを抑制できる。
本発明の第２特徴構成では、転動部からの基材のはみ出しに起因する、転写膜の転写不良の発生を抑制することができる。
【００１０】
【実施例】
〔第１実施例〕
図１〜図４は本発明の膜転写ローラー１０の概念図を示し、当該転写ローラー１０は、可撓性を備えた基材としてのテープ１の一側面を押圧しながら転動させ、当該テープ１の他側面に設けられている文字修正用塗膜、装飾用着色塗膜、接着用粘着膜等の粘着性を有する転写膜２を紙等の被転写面Ａに押圧転写する円筒状の合成樹脂又は天然樹脂製の転動部３を備え、前記テープ１と転写膜２とから構成される未使用の転写リボンＲを巻き付けて収納保持する収納部１１が設けられている膜転写具に、少なくとも転動部３の一部を外部に露出させた状態で回転自在に組付けられるとともに、その組付け状態では、前記転動部３の露出部分に、収納部１１から繰り出し供給された転写リボンＲが転写膜２側を外向きにして巻き掛けられて使用される。
前記膜転写ローラー１０は、合成樹脂製の筒軸４と、当該筒軸４に外嵌保持される円筒状の合成樹脂又は天然樹脂製の前記転動部３とから構成されていて、前記転動部３の回転軸芯Ｐ方向両端部の外周縁には、テープ１の一側面を押圧する転動部３の押圧周面３Ａから径方向外方に向かって、当該転動部３で転写膜２を被転写面Ａに転写可能なテープ１の厚みｔ１と転写膜２の厚みｔ２の和よりも大に突出する突出代Ｔを備えた突出部５が、円周方向に沿って環状に連続的に形成されている。
【００１１】
前記両突出部５の各々の横断面形状は対称な直角三角形状に形成されていて、当該両突出部５の転動部３の回転軸芯Ｐ方向両端面に連なる面がほぼ平行に構成されているとともに、両突出部５の回転軸芯Ｐ方向での相対向面５ａが、転動部３の押圧周面３Ａの径方向外方側ほど離間する傾斜面に構成されている。
前記両突出部５のうち、両傾斜面５ａの基端部分での対向間隔寸法、つまり、回転軸芯Ｐ方向における転動部３の押圧周面３Ａの幅Ｗ１は、テープ１の幅Ｗ２と同一寸法となるように構成され、テープ１が転動部３の押圧周面３Ａに位置する状態では、当該テープ１の一側面側の幅方向端縁が、両突出部５の傾斜面５ａに接当して、当該テープ１の回転軸芯Ｐ方向への移動が規制される。つまり、前記両傾斜面５ａが、テープ１の転動部３の回転軸芯Ｐ方向への移動を規制する規制面に構成される。
【００１２】
前記両突出部５を被転写面Ａに押圧接当したとき、当該両突出部５の接当部分は押圧力によって、転動部３の押圧周面３Ａから径方向外方に向かう突出代Ｔ１が、少なくともテープ１の厚みｔ１となるまで、互いに回転軸芯Ｐに沿う離間方向及び半径方向回転軸芯Ｐ側に弾性変形自在に構成され、転写膜２と被転写面Ａとの押圧接当、及び、テープ１と被転写面Ａとの押圧接当を共に許容できるように構成されている。
【００１３】
更に、前記転動部３の押圧周面３Ａで押圧される部位のテープ１部分に転写膜２が存在するとき（図１、図２に示す状態）、前記突出部５を被転写面Ａに押圧し、かつ、転写膜２と被転写面Ａとを押圧接当させた状態で転写方向下手側に移動操作すると、両突出部５の被転写面Ａとの接当に伴って転動部３に回転力が付与されて該転動部３は転動し、使用済転写リボンＲが転動部３とテープ１の一側面との摩擦力と、転写リボンＲの被転写面Ａに対する転写膜２の粘着力による固着とにより転動部３の転動方向下手側に送り出されるとともに、未使用の転写リボンＲが収納部１１側から転動部３に引き出される。
【００１４】
また、前記転動部３の押圧周面３Ａで押圧される部位のテープ１部分に転写膜２が存在しないとき（図３、図４に示す状態）、前記転動部３を被転写面Ａに押圧し、かつ、テープ１と被転写面Ａとを押圧接当させた状態で転写方向下手側に移動操作すると、両突出部５の被転写面Ａとの接当に伴って転動部３に回転力が付与されて該転動部３は転動し、転写膜２が存在しないテープ１部分が転動部３とテープ１の一側面との摩擦力により転動部３の転動方向下手側に送り出されるとともに、転写膜２が存在する未使用の転写リボンＲが収納部１１側から転動部３に引き出される。
【００１５】
尚、前記両突出部５の弾性変形部分の押圧力が解除されると、当該弾性変形部分は弾性的に復元する。
また、前記筒軸４の一方の端部には、当該筒軸４の外周面から径方向外方に張り出す環状の鍔部６が一体形成されている。
前記転動部３及び突出部５は、エラストマー、アクリロニトリルブタジエンゴム（ＮＢＲ）、又は、シリコーンゴム等の合成樹脂材料、或いは、天然ゴム等の天然樹脂材料から成形されているとともに、前記筒軸４及び鍔部６は、ポリアセタール、ポリプロピレン等の合成樹脂材料から成形されている。
次に、当該実施例の膜転写ローラー１０を組付けた前記膜転写具の一例として、接着用粘着膜（転写膜の一例）２を被転写面Ａに押圧転写する接着用粘着膜転写具を図５〜図８に基づいて説明する。
【００１６】
前記接着用粘着膜転写具は、厚さｔ１が０．０２５ｍｍで幅Ｗ２が８ｍｍの合成樹脂製テープ１の他側面に、接着用粘着膜２を０．０２ｍｍの厚さｔ２で塗布して構成された転写リボンＲが、転写膜２側を外向きにしてパンケーキ状に巻き付けられている合成樹脂製の円筒状の繰り出しコア（収納部の一例）１１と、前記膜転写ローラー１０と、当該膜転写ローラー１０の転動部３で転写膜２を被転写面Ａに転写したのちの使用済転写リボンＲを巻き取る合成樹脂製の円筒状の巻き取りコア１２とを、平板状の保持部材１３に各々回転自在に組付けて構成された転写リボンカセットＣＡを、後述する転写具ケースＣ内に着脱自在に装着して構成されている。
【００１７】
尚、前記被転写面Ａに押圧転写された転写膜２は、テープ１の他側面に塗布してあるシリコーン系の離型剤により、テープ１から剥離可能となっている。
また、前記接着用粘着膜転写具に用いられる前記膜転写ローラー１０の突出部５の突出代Ｔは０．１５ｍｍに構成され、かつ、突出部５の回転軸芯Ｐ方向での幅は０．７５ｍｍに構成されているとともに、回転軸芯Ｐ方向における転動部３の押圧周面３Ａの幅Ｗ１は８ｍｍに構成されている。
図５〜図７に示すように、前記各コア１１，１２は、そのリボン幅方向一端側に一体形成してある円筒状の回転軸１１Ａ，１２Ａを一体形成してあり、更に、これら回転軸１１Ａ，１２Ａには、保持部材１３に対する取付け用の環状溝を形成する鍔部１１ａ，１２ａを各々一体形成してある。
【００１８】
前記繰り出しコア１１の内周面には、転写具ケースＣ内に設けられている繰り出しコア用筒軸２１の外周面に一体形成してある係合突起２１ａに一体回転状態で係合する複数のリブ１１ｂを一体形成してあり、前記巻き取りコア１２の内周面には、前記転写具ケースＣ内に設けられている巻き取りコア用筒軸２３の外周面に形成してある凹凸面に一体回転状態で係合する突条を備えた４本の係止体１２ｂを一体形成してある。
図５に示すように、前記保持部材１３は、各コア１１，１２の鍔部１１ａ，１２ａと当該各コア１１，１２の一端面との間の環状溝、及び、膜転写ローラー１０の鍔部６と転動部３の一端面との間の環状溝に係入して、当該各コア１１，１２及び膜転写ローラー１０を片持ち姿勢で回転自在に遊嵌保持する繰り出しコア用保持孔１４と巻き取りコア用保持孔１５及び膜転写ローラー用保持孔１６を夫々円形状に貫通形成してある。
【００１９】
前記各保持孔１４，１５，１６には、各コア１１，１２及び膜転写ローラー１０の保持部材１３の外周縁側からの係脱を許容する繰り出しコア用案内通路１７、巻き取りコア用案内通路１８、膜転写ローラー用案内通路１９が、各保持孔１４，１５，１６と保持部材１３の外周縁のうちの一側縁とに亘ってほぼ平行状態で切り欠き形成してあり、各保持孔１４，１５，１６を保持部材１３の外周縁に対して同一方向に開口形成してある。
図６〜図８に示すように、前記転写具ケースＣは、リボン幅方向から接合可能な状態で合成樹脂材料により一体成形された本体ケース部材Ｃ１と蓋ケース部材Ｃ２とからなり、当該両ケース部材Ｃ１，Ｃ２の板状連設部分を肉薄に形成して揺動自在なヒンジ２０を構成するとともに、これらケース部材Ｃ１，Ｃ２を当該ヒンジ２０を介して開閉自在に構成してある。
【００２０】
前記一方の本体ケース部材Ｃ１内には、転写具ケースＣに転写リボンカセットＣＡを装着したとき、繰り出しコア１１のリブ１１ｂが係合する係合突起２１ａを備えた繰り出しコア用筒軸２１を回転のみ自在に外嵌保持する繰り出しコア用支軸２２と、巻き取りコア１２の係止体１２ｂの突条が係合する凹凸面を備えた巻き取りコア用筒軸２３を回転のみ自在に外嵌保持する巻き取りコア用支軸２４、及び、膜転写ローラー１０の筒軸４を回転自在に外嵌保持する膜転写ローラー用支軸２５を一体形成してある。
図６に示すように、前記繰り出し用筒軸２１には大径ギア２６が一体形成されているとともに、前記巻き取りコア用筒軸２３には小径ギア２７が一体形成されていて、これら両ギア２６，２７同士の噛合と、巻き取りコア用筒軸２３の凹凸面と係止体１２ｂの突条との噛合とで、繰り出しコア１１の回転と巻き取りコア１２の回転とを連動させ、転写具ケースＣ内に装填した転写リボンカセットＣＡの転写リボンＲの繰り出しにともなって繰り出しコア１１が回転すると、使用済の転写リボンＲが巻き取りコア１２に巻き取られるようギア連動機構２８を構成してあり、当該ギア連動機構２８は、転写リボンＲの繰り出しコア１１に対する巻き付け径が小さくなっても、繰り出しコア１１からのリボン繰り出し速度よりも巻き取りコア１２によるリボン巻き取り速度が速くなるよう両ギア２６，２７のギア径が設定されていて、使用済の転写リボンＲを巻き取りコア１２に確実に巻き取ることができるように構成してある。
【００２１】
尚、リボン繰り出し速度とリボン巻き取り速度との速度差により、前記転写リボンＲに過大な張力が作用した場合、巻き取りコア用筒軸２３の凹凸面と巻き取りコア１２の係止体１２ｂの突条とに一定以上の噛合力が生じ、係止体１２ｂが噛合解除方向（巻き取りコア１２の直径方向外方側）に弾性変形して、凹凸面と突条との噛合が解除されて巻き取りコア用筒軸２３と巻き取りコア１２との間の動力伝達が解除され、リボン繰り出し速度とリボン巻き取り速度との速度差が断続的に吸収されるように構成してある。
前記接着用粘着膜転写具は、図８に示すように、転写具ケースＣを把持した状態で転写リボンＲの転写膜２を被転写面Ａに押圧接当すると、前述の如く膜転写ローラー１０の両突出部５の接当部分が弾性変形して、転写膜２と被転写面Ａとが押圧接当するとともに、当該膜転写ローラー１０を、転写具ケースＣの移動操作により転写膜２の転写方向下手側に移動すると、被転写面Ａとの接当に伴って両突出部５を介して転動部３に回転力が付与され、転動部３も転動しながら転写膜２が被転写面Ａに転写される。
【００２２】
また、例えば、前回の転写膜２の転写時に、転動部３で押圧される部位よりも上手側の転写膜膜２が剥離されてしまい、転動部３で押圧される部位のテープ１部分に転写膜２が存在しないときでも、テープ１が被転写面Ａに押圧接当するまで両突出部５の接当部分を押圧力で弾性変形させて、膜転写ローラー１０を転写膜２の転写方向に移動すると、被転写面Ａとの接当に伴って両突出部５を介して転動部３に回転力が付与されて転動部３が転動するので、当該転動部３の押圧周面３Ａとテープ１の一側面との摩擦力により、転写膜２が存在しないテープ１部分が転動部３の回転方向下手側に送り出され、繰り出しコア１１側から転写膜２が存在するテープ１部分が引き出されてくる。
〔第２実施例〕
図９は、第１実施例の膜転写ローラーの別実施例を示し、前記転動部３の回転軸芯Ｐ方向両端部に、テープ１の厚みｔ１と転写膜２の厚みｔ２の和よりも大に突出する最大突出代Ｔを備えた回転軸芯Ｐ方向視で弧状の突出部５を、前記転動部３の押圧周面３Ａの円周方向に沿って連続的に形成されている。
【００２３】
その他の構成は第１実施例と同一である。

[Industrial application fields]
The present invention is a film transfer roller used when a transfer film having adhesive properties such as a character correcting coating film, a decorative colored coating film, an adhesive film for adhesion, and the like is pressed and transferred to a transfer surface such as paper, Specifically, it includes a rolling portion that rolls while pressing one side surface of a flexible base material and transfers a transfer film provided on the other side surface of the base material to the transfer surface. The present invention relates to a film transfer roller.
[0002]
[Prior art]
Conventionally, as this type of film transfer roller, the pressing peripheral surface of the rolling portion has been formed into a smooth circumferential surface across both ends in the direction of the rotation axis. For example, in JP-A-6-286927 As shown, when a flexible base material provided with a transfer film on the other side surface is wound around the feeding core, one side surface of the base material drawn from the feeding core is moved by the rolling part. Press the transfer film against the surface to be transferred while pressing, move the rolling part to the lower side in the transfer direction, and feed the substrate by the adhesive force of the transfer film to the surface to be transferred. There is a structure in which the transfer film is transferred to the surface to be transferred while the rolling portion is rolled by the frictional force between one side surface of the substrate and the pressing peripheral surface of the rolling portion.
[0003]
[Problems to be solved by the invention]
In general, on the other side of the base material provided with a transfer film that is pressed and transferred by this type of film transfer roller, the transfer film can be easily applied to the transfer surface even if the rolling part rolls with a weak pressing force. In order to be able to perform pressure transfer, a release agent made of silicone resin or the like is applied to improve the peelability of the transfer film from the substrate.
[0004]
Therefore, when the transfer film is transferred to the transfer surface, the transfer film is not pressed on the base portion of the portion pressed by the rolling part, for example, the transfer part is pressed at the previous transfer film transfer. In a state where the transfer film on the upper side than the part has been peeled off, the transfer surface A and the other side surface of the substrate 1 are in direct contact with each other as shown in FIG. Since the release agent is applied to the other side surface as described above, the coefficient of friction is low. In particular, when the transfer surface A is made of a relatively slippery material such as paper, 1 easily slips with respect to the transfer surface A, and even if the rolling part 03 is moved to the lower side in the transfer direction, it is difficult to pull out the transfer film together with the substrate 1 to the part pressed by the rolling part 03. . For this reason, there is a problem in that a transfer failure occurs on the transfer surface A of the transfer film.
The present invention has been made in view of the above circumstances, and due to a rational improvement of the transfer roller, even when there is no transfer film on the base portion of the portion pressed by the rolling portion at the start of use, It is an object of the present invention to provide a transfer roller capable of suppressing the occurrence of transfer failure of a transfer film as compared with the conventional case.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, the first feature of the present invention is that a transfer film provided on the other side surface of the substrate is rolled while pressing one side surface of the flexible substrate. A film transfer roller provided with a rolling part for transferring the film to the transfer surface, at least one end of the rolling part at both ends in the rotational axis direction, and radially outward from the pressing circumferential surface of the rolling part. A protrusion projecting larger than the sum of the thickness of the base material and the thickness of the transfer film toward the surface and imparting a rotational force to the rolling section in contact with the transfer surface. It is provided continuously or intermittently along the circumferential direction of the pressing peripheral surface of the moving portion, and is elastically deformable until the protruding portion allows the pressing contact between the transfer film and the transferred surface. It is in the point which is comprised.
According to a second characteristic configuration of the present invention, the projecting portions are provided at both ends of the rolling portion in the rotation axis direction, and opposing surfaces of both projecting portions are formed on the rolling portion of the base material. It is in the point comprised by the control surface which controls the movement to a rotating shaft core direction.
[0006]
[Action]
In the case of the first characteristic configuration of the present invention, the projecting portion is provided continuously or intermittently along the circumferential direction of the pressing peripheral surface of the rolling portion. Even when there is no transfer film on the material part, if one side of the substrate is pressed to the transfer surface side by the rolling part and moved downward in the transfer direction, the protrusion rotates while contacting the transfer surface. In addition, a rotational force is applied to the rolling part to cause the rolling part to roll, and the transfer film does not exist due to the frictional force between the pressing peripheral surface of the rolling part in this rolling state and one side surface of the substrate. Since the material portion is sent to the lower side in the rotation direction of the rolling portion, it is possible to suppress the occurrence of slip between the base material portion of the portion pressed by the rolling portion and the transfer surface, can withdraw transfer film to the substrate portion of the site to be pressed by the rolling unit, also rolling Utsushimaku is pressed transferred to the transferred surface Since Setto and a collision detecting portion and the transferred surface in that state, it can also be directly rolled without using the base rolling portion in this state.
[0007]
In addition, by configuring the protrusion margin of the protruding portion to be greater than the sum of the thickness of the substrate and the transfer film, the protrusion margin of the protruding portion is greater than or equal to the thickness of the substrate, and the thickness of the substrate and the transfer film Compared to the case where the thickness is equal to or less than the sum of the thicknesses, the dimensional accuracy of the maximum protrusion allowance of the protrusion can be roughened, and thus the protrusion can be easily manufactured and the substrate and the transfer film can be transferred. It can be located in the protrusion margin between the press surrounding surface of a moving part, and the front-end | tip of a protrusion part.
In the case of the second characteristic configuration of the present invention, even if the base material meanders, the movement of the base material in the direction of the rotation axis of the base material is restricted in the rolling part. There is almost no protrusion from the pressing peripheral surface of the part in the direction of the axis of rotation of the rolling part.
[0008]
【The invention's effect】
In the first characteristic configuration of the present invention, at the start of use, even when there is no transfer film on the base material portion of the portion that is pressed by the rolling portion, the base portion is moved by the rolling portion. feeding the rotational direction downstream side, since the substrate portion where the transfer film in the rotational direction upstream side is present can be moved to the rolling unit, it is possible to suppress the transfer failure of the transfer film as compared with the conventional occurs The friction force between the pressing peripheral surface of the rolling part and the substrate and the friction between the protruding part and the transferred surface can be obtained even during normal film transfer in which the transfer film is not missing. Since the rolling part rotates integrally with the base material due to the force, the base is compared with the case where the rolling part is rotated only by the frictional force between the pressing peripheral surface of the rolling part and the base material. The feeding movement from the rolling part of the material can be performed smoothly.
[0009]
In addition, since the transfer film is not pressed against the transferred portion unless the protruding portion is elastically deformed, the transfer film on the base portion of the portion pressed by the rolling portion is covered with careless care. Transfer to a transfer target portion or the like on the transfer surface can be suppressed.
In the second characteristic configuration of the present invention, it is possible to suppress the occurrence of transfer failure of the transfer film due to the protrusion of the base material from the rolling portion.

【Example】
[First embodiment]
1 to 4 are conceptual diagrams of a film transfer roller 10 according to the present invention. The transfer roller 10 rolls while pressing one side of a tape 1 as a base material having flexibility, and the tape 1. Cylindrical composition that press-transfers a transfer film 2 having adhesive properties such as a character correction coating film, a decorative colored coating film, and an adhesive film for adhesion, which is provided on the other side surface, onto a transfer surface A such as paper. A film transfer tool including a rolling part 3 made of resin or natural resin and provided with a storage part 11 for winding and storing and holding an unused transfer ribbon R composed of the tape 1 and the transfer film 2, The transfer ribbon is rotatably assembled with at least a part of the rolling part 3 exposed to the outside. In the assembled state, the transfer ribbon fed out and supplied from the storage part 11 to the exposed part of the rolling part 3 R is used with the transfer film 2 facing outwards That.
The film transfer roller 10 includes a cylindrical shaft 4 made of synthetic resin and the rolling portion 3 made of a cylindrical synthetic resin or natural resin that is fitted and held on the cylindrical shaft 4. On the outer peripheral edges of both ends of the moving part 3 in the rotation axis P direction, transfer is performed by the rolling part 3 from the pressing peripheral surface 3A of the rolling part 3 that presses one side surface of the tape 1 outward in the radial direction. A protrusion 5 having a protrusion margin T that protrudes larger than the sum of the thickness t1 of the tape 1 and the thickness t2 of the transfer film 2 capable of transferring the film 2 to the transfer surface A is annularly formed along the circumferential direction. It is formed continuously.
[0011]
The cross-sectional shape of each of the projecting parts 5 is formed in a symmetrical right triangle shape, and the surfaces of the projecting parts 5 connected to both end surfaces in the direction of the rotation axis P of the rolling part 3 are substantially parallel. In addition, the opposing surfaces 5 a in the direction of the rotation axis P of both projecting portions 5 are configured to be inclined surfaces that are separated toward the radially outer side of the pressing circumferential surface 3 A of the rolling portion 3.
Of the two protrusions 5, the opposing spacing dimension at the base end portions of both inclined surfaces 5 a, that is, the width W 1 of the pressing circumferential surface 3 A of the rolling portion 3 in the direction of the rotation axis P is the width W 2 of the tape 1. When the tape 1 is configured to have the same dimensions and the tape 1 is positioned on the pressing peripheral surface 3 </ b> A of the rolling portion 3, the width direction edge on one side of the tape 1 is formed on the inclined surfaces 5 a of both projecting portions 5. The contact of the tape 1 in the direction of the rotation axis P is restricted. That is, both the inclined surfaces 5 a are configured as a regulating surface that regulates the movement of the rolling portion 3 of the tape 1 in the direction of the rotation axis P.
[0012]
When the projecting portions 5 are pressed against the transfer surface A, the projecting allowance T1 of the contacting portions of the projecting portions 5 is directed radially outward from the pressing peripheral surface 3A of the rolling portion 3 by the pressing force. Until the thickness t1 of the tape 1 reaches at least the thickness t1 of the tape 1, it is configured to be elastically deformable in the separation direction and the radial direction rotation axis P side along the rotation axis P, and press contact between the transfer film 2 and the transfer surface A , And the press contact between the tape 1 and the transfer surface A can be allowed together.
[0013]
Further, when the transfer film 2 exists on the portion of the tape 1 that is pressed by the pressing peripheral surface 3A of the rolling portion 3 (the state shown in FIGS. 1 and 2), the protruding portion 5 is placed on the transfer surface A. When the pressing operation is performed and the transfer film 2 and the transfer surface A are pressed against each other and moved to the lower side in the transfer direction, the rolling portion is brought into contact with the transfer surface A of both protrusions 5. 3 is applied with a rotational force, and the rolling part 3 rolls, and the used transfer ribbon R transfers the frictional force between the rolling part 3 and one side surface of the tape 1 and the transfer surface A of the transfer ribbon R to the transfer surface A. The film 2 is fed to the lower side in the rolling direction of the rolling unit 3 due to the adhesion due to the adhesive force, and the unused transfer ribbon R is pulled out from the storage unit 11 side to the rolling unit 3.
[0014]
When the transfer film 2 is not present on the portion of the tape 1 that is pressed by the pressing peripheral surface 3A of the rolling part 3 (the state shown in FIGS. 3 and 4), the rolling part 3 is placed on the surface A to be transferred. When the tape 1 and the transfer surface A are pressed against each other and moved to the lower side in the transfer direction, the rolling portion is brought into contact with the transfer surface A of both protrusions 5. Rotating force is applied to 3 and the rolling portion 3 rolls, and the portion of the tape 1 where the transfer film 2 does not exist rolls the rolling portion 3 due to the frictional force between the rolling portion 3 and one side surface of the tape 1. In addition to being sent out to the lower side in the direction, the unused transfer ribbon R on which the transfer film 2 exists is drawn out from the storage unit 11 side to the rolling unit 3.
[0015]
In addition, when the pressing force of the elastically deforming portions of the two protrusions 5 is released, the elastically deforming portions are elastically restored.
Further, an annular flange 6 that projects radially outward from the outer peripheral surface of the cylindrical shaft 4 is integrally formed at one end of the cylindrical shaft 4.
The rolling part 3 and the protruding part 5 are molded from a synthetic resin material such as elastomer, acrylonitrile butadiene rubber (NBR), or silicone rubber, or a natural resin material such as natural rubber, and the cylindrical shaft 4 And the collar part 6 is shape | molded from synthetic resin materials, such as a polyacetal and a polypropylene.
Next, as an example of the film transfer tool assembled with the film transfer roller 10 of the embodiment, an adhesive film transfer tool for adhesive that presses and transfers an adhesive film (an example of a transfer film) 2 to the transfer surface A is provided. This will be described with reference to FIGS.
[0016]
The adhesive pressure-sensitive adhesive film transfer tool is configured by applying the adhesive pressure-sensitive adhesive film 2 with a thickness t2 of 0.02 mm to the other side of the synthetic resin tape 1 having a thickness t1 of 0.025 mm and a width W2 of 8 mm. The transferred transfer ribbon R is a cylindrical feeding core (an example of a storage unit) 11 made of a synthetic resin wound in a pancake shape with the transfer film 2 side facing outward, the film transfer roller 10, A cylindrical take-up core 12 made of a synthetic resin that takes up the used transfer ribbon R after the transfer film 2 is transferred to the transfer surface A by the rolling part 3 of the film transfer roller 10, and a flat holding member The transfer ribbon cassette CA, which is configured to be rotatably assembled to each other, is detachably mounted in a transfer tool case C described later.
[0017]
The transfer film 2 pressed and transferred to the transfer surface A can be peeled off from the tape 1 by a silicone release agent applied to the other side surface of the tape 1.
The protrusion T of the protrusion 5 of the film transfer roller 10 used in the adhesive film transfer tool for adhesion is configured to be 0.15 mm, and the width of the protrusion 5 in the direction of the rotation axis P is 0. The width W1 of the pressing circumferential surface 3A of the rolling part 3 in the direction of the rotation axis P is 8 mm.
As shown in FIGS. 5 to 7, the cores 11 and 12 are integrally formed with cylindrical rotating shafts 11 </ b> A and 12 </ b> A that are integrally formed on one end side in the ribbon width direction. 11A and 12A are integrally formed with flanges 11a and 12a that form an annular groove for attachment to the holding member 13, respectively.
[0018]
A plurality of engaging protrusions 21a integrally formed on the outer peripheral surface of the feeding core cylinder shaft 21 provided in the transfer tool case C are engaged with the inner peripheral surface of the feeding core 11 in an integrally rotated state. Ribs 11b are integrally formed, and an uneven surface formed on the outer peripheral surface of the take-up core cylinder shaft 23 provided in the transfer tool case C is formed on the inner peripheral surface of the take-up core 12. Four locking bodies 12b having protrusions engaged in an integrally rotating state are integrally formed.
As shown in FIG. 5, the holding member 13 includes an annular groove between the flanges 11 a and 12 a of the cores 11 and 12 and one end surface of the cores 11 and 12, and a flange of the film transfer roller 10. A feeding core holding hole 14 that engages in an annular groove between 6 and one end face of the rolling part 3 to freely loosely hold the cores 11 and 12 and the film transfer roller 10 in a cantilevered manner. The winding core holding hole 15 and the film transfer roller holding hole 16 are formed in a circular shape.
[0019]
The holding holes 14, 15, 16 have a feeding core guide passage 17 and a winding core guide passage 18 that allow the cores 11, 12 and the film transfer roller 10 to be engaged and disengaged from the outer peripheral edge side. The film transfer roller guide passage 19 is cut out in a substantially parallel state across each holding hole 14, 15, 16 and one side edge of the outer peripheral edge of the holding member 13. , 15 and 16 are formed in the same direction with respect to the outer peripheral edge of the holding member 13.
As shown in FIGS. 6 to 8, the transfer tool case C is composed of a main body case member C1 and a lid case member C2 which are integrally formed of a synthetic resin material in a state that can be joined from the ribbon width direction. The plate-like continuous portions of the members C1 and C2 are formed thin to constitute a swingable hinge 20, and the case members C1 and C2 are configured to be openable and closable via the hinge 20.
[0020]
In the one main body case member C1, when the transfer ribbon cassette CA is mounted on the transfer tool case C, the feeding core cylinder shaft 21 provided with the engaging projection 21a with which the rib 11b of the feeding core 11 is engaged is rotated. The take-up core support shaft 22 that is externally fitted and held only freely, and the take-up core cylinder shaft 23 that is provided with an uneven surface with which the protrusion of the locking body 12b of the take-up core 12 engages can be fitted only freely. A take-up core support shaft 24 to be held and a film transfer roller support shaft 25 to rotatably fit and hold the cylindrical shaft 4 of the film transfer roller 10 are integrally formed.
As shown in FIG. 6, a large-diameter gear 26 is integrally formed with the feeding cylinder shaft 21, and a small-diameter gear 27 is integrally formed with the winding core cylinder shaft 23. The rotation of the take-up core 11 and the rotation of the take-up core 12 are interlocked with each other by the meshing between 26 and 27 and the meshing of the concavo-convex surface of the take-up core cylinder shaft 23 and the protrusion of the locking body 12b The gear interlocking mechanism 28 is configured so that the used transfer ribbon R is wound around the take-up core 12 when the feed core 11 rotates as the transfer ribbon R of the transfer ribbon cassette CA loaded in the tool case C is fed. The gear interlocking mechanism 28 causes the winding core 12 to move faster than the ribbon feeding speed from the feeding core 11 even when the winding diameter of the transfer ribbon R around the feeding core 11 decreases. That the gear diameter of the both gears 26, 27 so that the ribbon take-up speed is increased is set, and are configured to be able to take reliably around the winding core 12 of the transfer ribbon R spent.
[0021]
When an excessive tension is applied to the transfer ribbon R due to the difference between the ribbon feeding speed and the ribbon winding speed, the uneven surface of the winding core cylinder shaft 23 and the locking body 12b of the winding core 12 A certain level of meshing force is generated on the ridge, and the locking body 12b is elastically deformed in the meshing release direction (diameter outward of the winding core 12), and the meshing between the concavo-convex surface and the ridge is released. The power transmission between the winding core cylinder shaft 23 and the winding core 12 is released, and the speed difference between the ribbon feeding speed and the ribbon winding speed is intermittently absorbed.
As shown in FIG. 8, when the transfer film 2 of the transfer ribbon R is pressed against the transfer surface A while holding the transfer tool case C as shown in FIG. The contact portions of the two protrusions 5 are elastically deformed so that the transfer film 2 and the transfer surface A are pressed against each other, and the transfer roller case 10 is moved by moving the transfer tool case C. When it moves to the lower side in the transfer direction, a rotational force is applied to the rolling part 3 via both protrusions 5 in contact with the transfer surface A, and the transfer film 2 is also rolled while the rolling part 3 rolls. It is transferred to the transfer surface A.
[0022]
Further, for example, when the transfer film 2 is transferred last time, the transfer film film 2 on the upper side of the portion pressed by the rolling portion 3 is peeled off, and the portion of the tape 1 at the portion pressed by the rolling portion 3 is removed. Even when the transfer film 2 is not present, the contact portions of both protrusions 5 are elastically deformed by pressing force until the tape 1 is pressed against the transfer surface A, and the film transfer roller 10 is transferred to the transfer film 2. When moving in the direction, a rotational force is applied to the rolling part 3 via both protrusions 5 with the contact with the transfer surface A, so that the rolling part 3 rolls. Due to the frictional force between the pressing peripheral surface 3A and one side surface of the tape 1, the portion of the tape 1 where the transfer film 2 does not exist is sent to the lower side in the rotational direction of the rolling part 3, and the transfer film 2 exists from the feeding core 11 side. tape 1 part is that we pulled out.
