Description

【０００１】
【発明の属する技術分野】
本発明は、ソーラーセルまたはエレクトロルミネッセンスを使用した時計用表示板の固定構造に関する。
【０００２】
【従来の技術】
モジュール上にエレクトロルミネッセンスを配設した時計用表示板の従来の固定構造を図６に示す。図６（ａ）は従来例の固定構造を示す正面図、図６（ｂ）は図６（ａ）のＡ−Ａ断面を示す拡大部分断面図、図６（ｃ）は図６（ａ）の係合固定部の拡大部分正面図である。以下、従来例を図を用いて説明する。
【０００３】
時計用表示板の従来の固定構造は、例えば、特許文献１のように、モジュール６上にエレクトロルミネッセンス５と時計用表示板４とを表示板固定部材３によって固定する構造である。
【０００４】
前記モジュール６の上面にはモジュール６よりやや小さい周形状からなるエレクトロルミネッセンス５が、両面テープ等の両面が粘着性を有する部材で粘着され、配設されている。
【０００５】
前記表示板固定部材３はリング状の樹脂成形体であり、下面の外周部に突出する前記モジュール６に固定するための突起である４個のフック７、及び表示板固定部材３の上面３ｂよりわずかに低く下方に下がった位置に形成され、上端の内方に突出するフランジ状の上面外周部３ａには前記時計用表示板４を固定するための２組の一対からなるピン状の円柱突部１ａ、１ｂを有している。
【０００６】
前記時計用表示板４には前記表示板固定部材３に配設された円柱突部１ａ、１ｂと係合するため、切欠２ａ、２ｂが円柱突部１ａ、１ｂに対応する位置に配設されている。また、前記一対の円柱突部１ａは、互いの間に隙間を有し、樹脂成形体の弾性を利用して、内側（隙間１０を狭める方向）に向かって弾性変形可能で、時計用表示板の切欠の幅１１と円柱突部の幅１２が等しいか、円柱突部の幅１２が大きくなるように、各部の寸法が設定されている。円柱突部１ｂについても同様であるため、説明は省略する。
【０００７】
つまり、本構造では、前記時計用表示板４の切欠側部８ａと円柱突部１ａが、各々の円柱突部１ａの中心から、対応する各々の切欠側部８ａへ垂線を下ろした箇所である接点９ａで接し、時計用表示板４と表示板固定部材３が係合固定されている。前記時計用表示板４の切欠側部８ｂ（図示せず）と、円柱突部１ｂについても同様であるため、説明は省略する。

【発明が解決しようとする課題】
しかしながら、従来における固定構造では、時計用表示板と表示板固定部材の接点は、表示板固定部材側の接点である円柱突部が円形状であるが故、表示板固定部材の円柱突部の大きさに依存して係合位置が変わる。よって、円柱突部の径を大きくすれば、どうしても時計用表示板の外周部に近い所で時計用表示板と円柱突部が接してしまい、衝撃により容易に時計用表示板が外れ、変形する可能性が高かった。
【００１０】
また、時計用表示板と円柱突部の接点を時計用表示板の内周部に近づけるためには、円柱突部の径を小さくする必要があるが、円柱突部の径を小さくすれば結果として円柱突部の弾性力が弱くなり（作用しにくくなり）、時計用表示板が外れやすくなる。また、円柱突部の径を小さくする事は表示板固定部材、特に円柱突部を成形すること自体が困難になり、結果として表示板固定部材への時計用表示板の取り付け、取り外し作業も困難になった。さらには、表示板固定部材及び時計用表示板の互いの寸法誤差を吸収できず、衝撃により容易に時計用表示板が外れ、変形してしまうこともあった。
【００１１】
本発明は、上記課題を解決し、表示板固定部材及び時計用表示板の互いの寸法誤差を容易に吸収でき、誰にでも簡単な作業にて時計用表示板の位置決めができ、表示板固定部材への時計用表示板の取り付け、取り外し作業が安易にできる時計用表示板の固定構造を提供するものである。さらに、時計用表示板と表示板固定部材の接点を時計用表示板の内周部に近づけ、時計の携帯使用中に起こる衝撃等による時計用表示板の外れ、変形を防止し、併せて表示板固定部材、時計用表示板の加工が容易となる時計用表示板の固定構造を提供するものである。
【００１２】
【課題を解決するための手段】
上記課題を解決するために、本発明の時計用表示板の固定構造は下記記載の構成を採用する。
【００１３】

【００２５】
本発明に係る時計用表示板の固定構造は、前記表示板固定部材が、エレクトロルミネッセンスまたはソーラーセルと同色調の色からなることが好ましい。
【００２６】

【００２７】
また、前記時計用表示板は、切欠側部の外周寄りに凸部を設けても良い。

【００３０】
【発明の実施の形態】
以下に、本発明に係る実施の形態を実施例により説明する。
【００３１】
（実施例１）
図１は本発明の時計用表示板の固定構造を示し、図１（ａ）は固定構造の平面図、図１（ｂ）は図１（ａ）のＢ−Ｂ断面における固定構造の一部を示す拡大部分断面図、図１（ｃ）は図１（ａ）の係合固定部の拡大部分正面図である。以下、図面を用いて説明する。
【００３２】
本実施例における時計用表示板の固定構造は、モジュール２６上にエレクトロルミネッセンス２５と時計用表示板２４とを表示板固定部材２３である補助リングによって固定する構造であって、前記表示板固定部材２３は、下面の外周部に突出する前記モジュール２６に固定するための固定部として、突起である４個のフック２７、及び上端の内方に突出するフランジ状の上面外周部２３ａに前記時計用表示板２４を固定するための２個の柱状部２１ａ、２１ｂを有している。前記時計用表示板２４は、外周部に前記表示板固定部材２３の柱状部２１ａ、２１ｂに係合固定するための２個の切欠２２ａ、２２ｂを有しており、上面に予めエレクトロルミネッセンス２５が配設されているモジュール２６に前記表示板固定部材２３の突起であるフック２７を係合固定させ、前記表示板固定部材２３の柱状部２１ａ、２１ｂに前記時計用表示板２４の切欠２２ａ、２２ｂを各々係合固定させる。
【００３３】
前記モジュール２６の上面には、モジュール２６よりやや小さい周形状からなるエレクトロルミネッセンス２５が、両面テープ等の両面が粘着性を有する部材で粘着され、配設されている。
【００３４】
また、表示板固定部材２３は、外観上目立たなくする目的から、前記エレクトロルミネッセンス２５と同調色であるモスグリーンの色調からなるリング状の樹脂成形体である。そして、前記表示板固定部材２３を前記モジュール２６の外方に配設し、前記表示板固定部材２３に形成されている突起である４個のフック２７によって前記表示板固定部材２３と前記モジュール２６とを係合固定するように構成されている。
【００３５】
さらに、表示板固定部材２３の上面２３ｂよりわずかに低く下方に下がった位置に形成されている前記表示板固定部材２３の上面外周部２３ａの上面には、柱状部２１ａ、２１ｂが各々１２時側と６時側との２箇所に配設されている。また、前記柱状部２１ａ、２１ｂは水平方向の断面が略台形形状をしており、略台形形状は外周部に近づくほど時計用表示板２４の切欠底部３０ａ、３０ｂと平行方向の幅が狭くなっている。前記柱状部２１ａ、２１ｂは、樹脂成形体の弾性を利用して、切欠側部２８ａ、２８ｂ（図示せず）と接した際に圧縮弾性変形が可能になるように、各部の寸法が設定されている。
【００３６】
一方、前記時計用表示板２４は、アクリル、ポリカーボネイト等よりなる薄板状の透明体からなり、目盛り、ペットネーム、数字、模様等の仕様が印刷、塗装等により施されている。
【００３７】
前記時計用表示板２４の外周部には、外方に向かって開口し、かつ前記時計用表示板２４の上面から下面に貫通された切欠２２ａ、２２ｂが、１２時側と６時側の２箇所に各々形成されている。
【００３８】
また、図２に示すように、前記表示板固定部材２３の１２時側の柱状部の幅３９ａは、柱状部において内周部寄りに位置し、また、前記時計用表示板の切欠の幅４０ａと等しいか、あるいはわずかに大きく設定されている。すなわち、３９ａ≧４０ａの関係を満たすように構成されている。６時側の柱状部の幅３９ｂ（図示せず）と時計用表示板の切欠の幅４０ｂ（図示せず）についても同様であるため、説明は省略する。
【００３９】
この結果、柱状部２１ａ、２１ｂが時計用表示板２４の切欠側部２８ａ、２８ｂと接した際に圧縮弾性変形することで係合固定させ、前記時計用表示板２４を固定することができる。さらに、柱状部の幅３９ａ、３９ｂ及び時計用表示板の切欠の幅４０ａ、４０ｂとの寸法のばらつきを吸収することが可能となり、係合固定力が安定する。
【００４０】
さらに、柱状部２１ａと切欠２２ａとの接点２９ａは、柱状部２１ａが切欠側部２８ａと内周部寄りで接するため、切欠側部２８ａの内周部寄りにある。つまり時計用表示板２４の内周部で係合固定できる。柱状部２１ｂ、切欠２２ｂでも同様（接点２９ｂは図示せず）であるため、説明は省略する。
【００４１】
また、前記時計用表示板２４の切欠２２ａの平面形状の例を図３に示したが、図３（ａ）に示すように、前記時計用表示板２４の切欠側部２８ａの外周寄り両側に外方に向かって開口する面取り３１を設けることで、前記表示板固定部材２３の柱状部２１ａを係合固定させる作業を容易、かつ安定させる効果を有している。あるいは図３（ｂ）に示すように、前記切欠側部２８ａの外周寄り両側に凸部３２を設けても良い。この場合、前記凸部３２は時計用表示板２４の外れ防止用ストッパーとしても役立つ。図３（ａ）の場合、切欠の狭い方の幅を、図３（ｂ）の場合、切欠の広い方の幅を時計用表示板の切欠の幅４０ａとする。なお、時計用表示板２４の切欠２２ｂと、表示板固定部材２３の柱状部２１ｂについては、前記時計用表示板２４の切欠２２ａと、表示板固定部材２３の柱状部２１ａの場合と同様であるため、説明は省略する。なおまた、切欠２２ａ、２２ｂの平面形状は図２（ｂ）のようでも問題ないことは言うまでもない。
【００４２】
さらに、図４に時計用表示板２４の切欠２２ａの断面形状の例を示したが、図４（ｃ）に示すように、切欠２２ａのエレクトロルミネッセンスと接する面に向かって開口する両側に面取り３５を設けるか、あるいは図４（ｄ）に示すように、前記切欠２２ａのエレクトロルミネッセンスと接する面に向かって開口する両側に、わずかに広がる斜面３６を設けても良い。この場合は、いずれも切欠の小さい方の幅を４０ａとする。時計用表示板２４の切欠２２ｂの場合も前記と同様のため説明は省略する。これらも同様に、前記表示板固定部材２３の柱状部２１ａ、２１ｂに前記時計用表示板２４の切欠２２ａ、２２ｂを各々係合固定させる作業を容易、かつ安定させる効果を有している。なお、図４（ｂ）に示すように、ストレート形状でも問題ないことは言うまでもない。なおまた、前記図３の構造と、前記図４の構造を併せた構造を有しても何ら問題はない。
【００４３】
また、前記表示板固定部材２３の円柱突部２１ａ、２１ｂと、前記時計用表示板２４の切欠２２ａ、２２ｂとは１２時側と６時側に各々整合する位置に配設されている。
【００４４】
次に、本実施例における時計用表示板２４の取り付け、取り外し方法について説明する。まず、前記表示板固定部材２３の下面側からエレクトロルミネッセンス２５が配設されているモジュール２６を挿入し、位置決めを行いながら前記モジュール２６の外方に前記表示板固定部材２３を配設し、前記表示板固定部材２３に形成されている突起である４個のフック２７によって前記表示板固定部材２３と前記モジュール２６とを係合固定する。この位置決めは、図示しないが、前記表示板固定部材２３に設ける突出部と前記モジュール２６に設ける切欠部の位置を各々整合させれば良く、作業者が目視により極めて容易に、かつ間違いなく行えるものである。
【００４５】
次に、前記表示板固定部材２３の上面２３ｂに前記時計用表示板２４を係合固定する。まず、前記時計用表示板２４を、前記表示板固定部材２３の上面２３ｂに載置する。この位置決めは、前記上面外周部２３ａに形成されている１２時側と６時側との２組の柱状部２１ａ、２１ｂと前記時計用表示板２４に形成されている２つの切欠２２ａ、２２ｂとの位置を各々整合させれば良く、作業者が目視により極めて容易に、かつ間違いなく行えるものである。
【００４６】
次に、前記時計用表示板２４を下方に押圧して、前記２組の柱状部２１ａ、２１ｂを時計用表示板２４の切欠側部２８ａ、２８ｂと接した際に圧縮弾性変形させながら各々軽圧入させることによって、簡単に、表示板固定部材２３と時計用表示板２４とを係合固定することができる。
【００４７】
さらに、図３、図４に示すように、時計用表示板２４の切欠２２ａ、２２ｂに設ける斜面３６、あるいは面取り３１、３５が、切欠２２ａ、２２ｂに前記柱状部２１ａ、２１ｂを各々軽圧入させるときの案内となり、表示板固定部材２３への時計用表示板２４の取り付け、取り外しが容易となり、かつ安定化する。また、柱状部２１ａ、２１ｂは外周部に向かうほど時計用表示板の切欠底部と平行方向の幅が狭くなるので、より取り付けやすい構造となっている。
【００４８】
したがって、本実施例における時計用表示板の固定構造によれば、切欠２２ａ、２２ｂに柱状部２１ａ、２１ｂが圧入された状態で固定されているため、係合された前記時計用表示板２４は、水平方向の外力が負荷されても、固定された状態を保つことができる。また、ピンセット等で前記時計用表示板２４の外周部を上方に押圧して、前記切欠２２ａ、２２ｂと前記柱状部２１ａ、２１ｂとの係合を解除すれば、前記時計用表示板２４は、容易に前記表示板固定部材２３より取り外すことができる。
【００４９】
さらに、本実施例における時計用表示板の固定構造によれば、柱状部の幅３９ａ、３９ｂと、時計用表示板の切欠の幅４０ａ、４０ｂとの寸法のばらつきが吸収され、表示板固定部材２３と時計用表示板２４との位置決め、係合固定力が安定する。また、本実施例における時計用表示板２４には、小さい突起部がないため、外部からの衝撃による変形を防止することができる。
【００５０】
（実施例２）
図５は、本発明の時計用表示板の固定構造を示し、図５（ａ）は固定構造の平面図、図５（ｂ）は、図５（ａ）のＣ−Ｃ断面における固定構造の一部を示す拡大部分断面図である。以下、図面を用いて説明する。
【００５１】
本実施例における時計用表示板の固定構造は、図５に示すように、モジュール２６の上面にソーラーセル３８を配設し、時計用表示板３４の回転防止及び位置ずれ防止をするために、時計用表示板３４に２組の切欠３７ａ、３７ｂ及び表示板固定部材３３である補助リングに２組の柱状部３２ａ、３２ｂを３時側、９時側に各々設けた。その他は前記実施例１と同様であるため、実施例１と同じ構成要素には同じ番号、名称を使用し、説明は省略する。
【００５２】
前記モジュール２６の上面にはモジュール２６よりやや小さい周形状からなるソーラーセル３８が両面テープ等の両面が粘着性を有する部材で粘着され、配設されている。
【００５３】
また、表示板固定部材３３は、外観上目立たなくする目的から、前記ソーラーセル３８と同調色であるダークグレーの色調からなるリング状の樹脂成形体である。そして、前記表示板固定部材３３を前記モジュール２６の外方に配設し、前記表示板固定部材３３に形成されている４個の突起であるフック２７によって前記表示板固定部材３３と前記モジュール２６とを係合固定するように構成されている。
【００５４】
さらに、表示板固定部材３３の上面３３ｂよりわずかに低く、下方に下がった位置に形成されている前記表示板固定部材３３の上面外周部３３ａの上面には、時計用表示板３４を固定するための柱状部２１ａ、２１ｂが各々１２時側と６時側との２箇所に配設されていて、さらに、時計用表示板３４の回転防止及び位置ずれを防止するための柱状部３２ａ、３２ｂが各々３時側と９時側との２箇所に配設されている。前記柱状部２１ａ、２１ｂは、実施例１と同様であるため説明を省略する。
【００５５】
また、前記柱状部３２ａ、３２ｂは、前記柱状部２１ａ、２１ｂと同様に水平方向の断面は略台形形状をしている。また、柱状部２１ａ、２１ｂと切欠底部３０ａ、３０ｂの関係と同様に、柱状部３２ａ、３２ｂは外周部に近づくほど時計用表示板３４の切欠底部３０ｃ、３０ｄと平行方向の幅が狭くなっている。前記柱状部３２ａ、３２ｂも、柱状部２１ａ、２１ｂと同様に樹脂成形体の弾性を利用して、３時側と９時側の前記時計用表示板３４の各切欠側部２８ｃ（図示せず）、２８ｄ（図示せず）と接した際に圧縮弾性変形が可能になるように、各部の寸法が設定されている。
【００５６】
一方、前記時計用表示板３４は、アクリル、ポリカーボネイト等よりなる薄板状の透明体からなり、目盛り、ペットネーム、数字、模様等の仕様が、印刷、塗装等により施されている。
【００５７】
前記時計用表示板３４の上面から下面に貫通された表示板固定部材３３へ固定するための切欠２２ａ、２２ｂが１２時側と６時側との２箇所に各々形成されていて、さらに、時計用表示板３４の回転防止及び位置ずれを防止するための切欠３７ａ、３７ｂが３時側と９時側との２箇所に各々形成されている。
【００５８】
また、前記切欠３７ａ、３７ｂの平面、あるいは断面形状は、実施例１で説明した切欠２２ａ、２２ｂと同様に面取り、または斜面が形成されていることが好ましい。これについては実施例１と同様であるため、詳細な説明を省略する。
【００５９】
また、前記表示板固定部材３３の固定用の柱状部２１ａ、２１ｂと、前記時計用表示板３４の切欠２２ａ、２２ｂとは、１２時側と６時側に各々整合する位置に配設され、同様に、回転防止及び位置ずれ防止用の柱状部３２ａ、３２ｂと、前記時計用表示板３４の切欠３７ａ、３７ｂとは３時側と９時側に各々整合する位置に配設されている。
【００６０】
また、前記表示板固定部材３３の３時側と９時側の柱状部３２ａ、３２ｂの幅は、前記時計用表示板３４の切欠３７ａ、３７ｂの幅と等しいか、あるいはわずかに大きく設定されている。これについても、前記実施例１で説明した前記柱状部２１ａ、２１ｂの幅と、前記切欠２２ａ、２２ｂの幅との関係と同様であるため、説明を省略する。
【００６１】
また、本実施例における時計用表示板３４の取り付け、取り外し方法については、前記実施例１と同様であるため説明を省略する。
【００６２】
以上のように、本実施例によれば、実施例１と同様の効果が得られると共に、回転防止及び位置ずれ防止用の柱状部３２ａ、３２ｂと、切欠３７ａ、３７ｂとを設けることにより、前記時計用表示板３４の固定はもとより、回転防止や位置ずれ防止を確実にすることができる。本発明によれば、表示板固定部材の柱状部と時計用表示板の切欠の接点が時計用表示板の内周部にあるため、係合固定の効果はより顕著である。
【００６３】
なお、上記実施例においては、表示板固定部材３３の柱状部２１ａ、２１ｂ、３２ａ、３２ｂと、前記時計用表示板３４の切欠２２ａ、２２ｂ、３７ａ、３７ｂとについて、１２時側と６時側や、３時側と９時側の各々２箇所に設ける例で説明したが、表示板固定部材の中心を介して略相対する位置に設けてあれば前記の箇所のみならず問題ないことは言うまでもない。さらに、略相対する位置だけでなく、少しずらした位置に設けても問題ない。
【００６４】
なおまた、柱状部２１ａ、２１ｂ、３２ａ、３２ｂは水平方向の断面を略台形形状として説明したが、各々の頂点は角張っていることはもちろん、Ｒ形状を有していても良い。また、水平方向の断面は略台形形状でなく、略三角形形状でも良い。
【００６５】
さらに、上記実施例においては、表示板固定部材として補助リングについて説明したが、表示板の固定構造としては支持枠、中枠等でも良い。
【００６６】
上記実施例においては、モジュール２６に固定するため、表示板固定部材２３及び３３の下方に固定部として突起であるフック２７を設けたが、表示板固定部材２３及び３３の下方の内壁に突起を設け、この突起をモジュール２６の側壁に圧接して固定する方法としても良い。
【００６７】
【発明の効果】
以上のように、本発明による時計用表示板の固定構造によれば、表示板固定部材及び時計用表示板の互いの寸法誤差を容易に吸収できるので、時計用表示板を表示板固定部材に確実に固定することができる。また、誰にでも簡単な作業で時計用表示板の位置決めができ、表示板固定部材と時計用表示板の取り付け、取り外し作業が容易となり、作業性が向上する。さらに、表示板固定部材に配設した柱状部を本発明の構造にすることにより、衝撃による時計用表示板の変形防止や、併せて表示板固定部材、時計用表示板の加工を容易にすることができる。また、固定用柱状部に加えて、回転防止及び位置ずれ防止用の柱状部も有するため、時計用表示板の回転防止及び位置ずれ防止を確実に行うことができる。さらに、時計用表示板と表示板固定部材の接点（係合固定位置）が、時計用表示板の内周部にあるため、係合固定力も大きくすることができる。

Are respectively engaged and fixed.
[0033]
On the upper surface of the module 26, an electroluminescence 25 having a slightly smaller circumferential shape than that of the module 26 is provided by being adhered with a member having an adhesive property on both sides such as a double-sided tape.
[0034]
The display panel fixing member 23 is a ring-shaped resin molded body having a moss-green color tone that is tuned to the electroluminescence 25 for the purpose of making the appearance less noticeable. Then, the display plate fixing member 23 is disposed outside the module 26, and the display plate fixing member 23 and the module 26 are fixed by four hooks 27 which are projections formed on the display plate fixing member 23. Are configured to be engaged and fixed.
[0035]
Further, on the upper surface of the outer peripheral portion 23a of the upper surface of the display plate fixing member 23 which is formed at a position slightly lower and lower than the upper surface 23b of the display plate fixing member 23, columnar portions 21a and 21b are respectively provided on the 12 o'clock side. And 6 o'clock side. The columnar portions 21a and 21b have a substantially trapezoidal cross section in the horizontal direction, and the width of the substantially trapezoidal shape in the direction parallel to the notch bottom portions 30a and 30b of the timepiece display panel 24 becomes narrower toward the outer peripheral portion. ing. The dimensions of each of the columnar portions 21a and 21b are set so that compression elastic deformation is possible when the columnar portions 21a and 21b come into contact with the cutout side portions 28a and 28b (not shown) by using the elasticity of the resin molded body. ing.
[0036]
On the other hand, the timepiece display panel 24 is made of a thin transparent body made of acrylic, polycarbonate, or the like, and is provided with specifications such as scales, pet names, numbers, and patterns by printing, painting, and the like.
[0037]
Notches 22a and 22b, which open outward and penetrate from the upper surface to the lower surface of the timepiece display plate 24, are provided on the outer peripheral portion of the timepiece display plate 24. It is formed in each place.
[0038]
As shown in FIG. 2, the width 39a of the column portion on the 12 o'clock side of the display panel fixing member 23 is located closer to the inner peripheral portion of the column portion, and the width 40a of the notch of the timepiece display plate is set. Equal to or slightly larger. That is, it is configured to satisfy the relationship of 39a ≧ 40a. The same applies to the width 39b (not shown) of the column portion on the 6 o'clock side and the width 40b (not shown) of the notch of the timepiece display panel, and a description thereof will be omitted.
[0039]
As a result, when the columnar portions 21a, 21b come into contact with the notched side portions 28a, 28b of the timepiece display plate 24, they are engaged and fixed by being compressed and elastically deformed, and the timepiece display plate 24 can be fixed.

The provision of the chamfer 31 that opens outward has an effect of facilitating and stabilizing the operation of engaging and fixing the columnar portion 21a of the display panel fixing member 23. Alternatively, as shown in FIG. 3 (b), convex portions 32 may be provided on both sides near the outer periphery of the cutout side portion 28a. In this case, the convex portion 32 also serves as a stopper for preventing the clock display panel 24 from coming off. In the case of FIG. 3A, the width of the narrower notch is defined as the width of the notch 40a of the timepiece display panel, and in the case of FIG. 3B, the wider width of the notch is defined. The notch 22b of the timepiece display plate 24 and the columnar portion 21b of the display plate fixing member 23 are the same as those of the notch 22a of the timepiece display plate 24 and the columnar portion 21a of the display plate fixing member 23. Therefore, description is omitted. In addition, it goes without saying that the planar shape of the notches 22a and 22b does not matter even if it is as shown in FIG.
[0042]
Further, FIG. 4 shows an example of the cross-sectional shape of the notch 22a of the timepiece display panel 24. As shown in FIG. 4C, chamfers 35 are formed on both sides of the notch 22a which open toward the surface in contact with the electroluminescence. Alternatively, as shown in FIG. 4D, a slightly widened slope 36 may be provided on both sides of the notch 22a opening toward the surface in contact with the electroluminescence. In this case, the width of the smaller notch is 40a. The same applies to the case of the notch 22b of the timepiece display panel 24, and a description thereof will be omitted. Similarly, these also have the effect of facilitating and stabilizing the operation of engaging and fixing the notches 22a, 22b of the timepiece display plate 24 to the columnar portions 21a, 21b of the display plate fixing member 23, respectively. Needless to say, as shown in FIG. In addition, there is no problem even if it has a structure combining the structure of FIG. 3 and the structure of FIG.
[0043]
Further, the cylindrical projections 21a and 21b of the display panel fixing member 23 and the notches 22a and 22b of the timepiece display panel 24 are arranged at positions matching the 12 o'clock side and the 6 o'clock side, respectively.
[0044]
Next, a method of attaching and detaching the timepiece display panel 24 in the present embodiment will be described. First, a module 26 provided with the electroluminescence 25 is inserted from the lower surface side of the display panel fixing member 23, and the display panel fixing member 23 is disposed outside the module 26 while performing positioning. The display panel fixing member 23 and the module 26 are engaged and fixed by four hooks 27 which are projections formed on the display panel fixing member 23. Although this positioning is not shown, the position of the projection provided on the display panel fixing member 23 and the position of the notch provided on the module 26 may be aligned with each other. It is.
[0045]
Next, the timepiece display plate 24 is engaged and fixed to the upper surface 23b of the display plate fixing member 23. First, the timepiece display plate 24 is placed on the upper surface 23 b of the display plate fixing member 23. This positioning is performed by two sets of columnar portions 21a and 21b of 12 o'clock side and 6 o'clock side formed on the outer peripheral portion 23a of the upper surface, and two notches 22a and 22b formed on the timepiece display plate 24. Can be adjusted, and the operator can visually and easily perform the operation without fail.
[0046]
Next, the timepiece display plate 24 is pressed downward to lightly compress and elastically deform the two sets of columnar portions 21a and 21b when they come into contact with the cutout side portions 28a and 28b of the timepiece display plate 24. By press-fitting, the display plate fixing member 23 and the timepiece display plate 24 can be easily engaged and fixed.
[0047]
Further, as shown in FIGS. 3 and 4, the slopes 36 or the chamfers 31 and 35 provided in the notches 22a and 22b of the timepiece display panel 24 lightly press the columnar portions 21a and 21b into the notches 22a and 22b. It becomes a guide at the time, and the attachment and detachment of the clock display plate 24 to and from the display plate fixing member 23 become easy and stable. Further, the width of the columnar portions 21a and 21b in the direction parallel to the notch bottom of the timepiece display panel becomes narrower toward the outer peripheral portion, so that the structure is easier to attach.
[0048]
Therefore, according to the structure for fixing the timepiece display plate in the present embodiment, since the columnar portions 21a and 21b are fixed in the notches 22a and 22b in a state of being press-fitted, the engaged timepiece display plate 24 is Even if a horizontal external force is applied, the fixed state can be maintained. When the outer peripheral portion of the timepiece display plate 24 is pressed upward with tweezers or the like to disengage the notches 22a, 22b and the columnar portions 21a, 21b, the timepiece display plate 24 becomes It can be easily removed from the display panel fixing member 23.
[0049]
Furthermore, according to the structure for fixing the timepiece display panel in the present embodiment, the dimensional variation between the width 39a, 39b of the columnar portion and the width 40a, 40b of the notch of the timepiece display plate is absorbed, and the display plate fixing member is absorbed. The positioning and engagement fixing force between the watch 23 and the timepiece display panel 24 are stabilized. In addition, since the timepiece display panel 24 in the present embodiment does not have a small projection, deformation due to an external impact can be prevented.
