Description

【０００１】
【発明の属する技術分野】
この発明は、封印装置及び封印部材に係わり、特に、タクシーメータ等の封印を行うための封印装置及びその封印装置に用いられる封印部材に関する。
【０００２】
【従来の技術】
従来、上述した封印装置として、図８乃至図１０に示すタクシーメータが提案されている。図８は、タクシーの料金演算を行うための制御基板等を搭載したタクシーメータ（＝対象機器）を収納するメータケース１００（＝筐体）の部分斜視図である。同図に示すように、メータケース１００は、開口部１０１が形成されている。この開口部１０１の内周壁には凸部１０２が突設されている。
【０００３】
また図９は、上記メータケース１００を封印する封印部材２００の斜視図である。同図に示すように、封印部材２００は、弾性部材からなり、メータケース１００の開口部１０１に突設された凸部１０２と係合する凹部２０１が、その外周面に沿って形成されている。そして、この封印部材２００は、図１０に示すように、メータケース１００の凸部１０２に凹部２０１を係合させることで、メータケース１００の開口部１０１に取着されるように構成されている。
【０００４】
次に、メータケース１００に取着された封印部材２００の封印解除手順を以下説明する。まず最初に、先端の鋭い例えば千枚通し３００で、封印部材２００の天面２０２を突き刺す。そして、千枚通し３００を天面２０２に突き刺した状態でこじることにより、凸部１０２と凹部２０１との係合を外し、封印を解除している。
【０００５】
以上のように、封印部材２００の天面２０２を千枚通し３００で突き刺して破壊しないと、封印を解除できないようにすることにより、メータケース１００内に収納された制御基板等の交換が不正に行われないようにしている。
【０００６】
【発明が解決しようとする課題】
しかしながら、上述した封印装置は、千枚通し３００により封印部材２００を強引にこじることにより、封印解除を行っている。このため、凸部１０２の摩耗が繰り返され、ついにはメータケース１００は、その凸部１０２と封印部材２００の凹部２０１との係合ができなくなり、封印ができなくなるという事態が発生する恐れがある。
【０００７】
また、千枚通し３００により封印部材２００を強引にこじる際に、本体壁１０３を支点に千枚通し３００をこじったりすると本体壁１０３に傷が付いてしまうという問題があった。さらに、千枚通し３００を突き刺しすぎた場合には、メータケース１００内部の制御基板４００等を傷つけてしまうという問題もあった。
【０００８】
そこで、本発明は、上記のような問題点に着目し、筐体自体や、該筐体に収納された対象機器を傷つけずに、封印解除を行うことができる封印装置及びその封印装置に用いられる封印部材を提供することを課題とする。
【０００９】
【課題を解決するための手段】
上記課題を解決するためになされた請求項１記載の発明は、対象機器を内面上に搭載して収容する筐体と、前記対象機器と対向して前記筐体に設けられた開口部を覆う被破壊部、該被破壊部に連接されて前記開口部を通して該筐体内に挿入される係合部及び該係合部に設けられて前記筐体の開口部内周と係合する係合手段を有する封印部材と、を備えた封印装置であって、前記被破壊部が、前記係合手段と係合する前記筐体の開口部内周側の端部から前記係合手段の係合解除方向に沿って延在して設けられ、かつ前記係合部を挟んで設けられた左右脆弱部を有していることを特徴とする封印装置に存する。
【００１０】
請求項１記載の発明によれば、筐体が、対象機器を内面上に搭載して収容している。封印部材が、対象機器と対向して筐体に設けられた開口部を覆う被破壊部、該被破壊部に連接されて開口部を通して該筐体内に挿入される係合部及び該係合部に設けられて筐体の開口部内周と係合する係合手段を有している。さらに、封印部材の被破壊部において、左右脆弱部が、係合手段と係合する筐体の開口部内周側の端部から係合手段の係合解除方向に沿って延在して設けられ、かつ係合部を挟んで設けられている。
【００１１】
以上の構成により、左右脆弱部間の被破壊部を、例えばマイナスドライバー等により筐体側に押すと、被破壊部の端部から左右脆弱部がせん断破壊する。このため、左右脆弱部間の破壊面が、係合部を中心とした係合手段側と反対側に曲げられ、左右脆弱部間の破壊面と連接された係合部に設けられた係合手段も前記反対側に曲げられる。この結果、筐体と係合手段とをこすりあわせることなく、筐体との係合を解除することができる。
【００１２】
請求項２記載の発明は、対象機器を内面上に搭載して収容する筐体と、前記対象機器と対向して前記筐体に設けられた開口部を覆う被破壊部、該被破壊部に連接されて前記開口部を通して該筐体内に挿入される係合部及び該係合部に設けられて前記筐体の開口部内周と係合する係合手段を有する封印部材と、を備えた封印装置であって、前記被破壊部が、前記係合手段の係合解除方向に沿って延在して設けられ、かつ前記係合部を挟んで設けられた左右脆弱部と、前記係合手段側の前記左右脆弱部間を結ぶ脆弱部とを有していることを特徴とする封印装置に存する。
【００１３】
請求項２記載の発明によれば、筐体が、対象機器を内面上に搭載して収容している。封印部材が、対象機器と対向して筐体に設けられた開口部を覆う被破壊部、該被破壊部に連接されて開口部を通して該筐体内に挿入される係合部及び該係合部に設けられて筐体の開口部内周と係合する係合手段を有する。さらに、封印部材の被破壊部が、係合手段の係合解除方向に沿って延在して設けられ、かつ係合部を挟んで設けられた左右脆弱部と、係合手段側の左右脆弱部間を結ぶ脆弱部とを有する。
【００１４】
以上の構成により、左右脆弱部間であり、かつ脆弱部より係合手段側と反対側の被破壊部を、例えばマイナスドライバー等により筐体側に押すと、脆弱部及び左右脆弱部がせん断破壊する。このため、脆弱部より係合手段側と反対側であり、かつ左右脆弱部間の破壊面が、係合手段側と反対側に曲げられ、左右脆弱部間の破壊面と連接された係合部に設けられた係合手段も前記反対側に曲げられる。この結果、筐体と係合手段とをこすりあわせることなく、筐体との係合を解除することができる。
【００１５】
請求項３記載の発明は、請求項１又は、２記載の封印装置であって、前記筐体は、前記左右脆弱部を中心とした前記左右脆弱部間側と反対側の被破壊部を支持する支持部を有することを特徴とする封印装置に存する。
【００１６】
請求項３記載の発明によれば、筐体内の支持部が、左右脆弱部を中心とした左右脆弱部間と反対側の被破壊部を支持する。従って、左右脆弱部間の破壊部を、例えばマイナスドライバー等により筐体側に押したとき、その力が左右脆弱部を中心とした左右脆弱間側と反対側の支持部により支持される。このため、押す力が効果的に、左右脆弱部のせん断破壊に使われる。
【００１７】
請求項４記載の発明は、請求項１〜３何れか１項記載の封印装置であって、前記被破壊部は、前記筐体側の面と相対する面上の前記左右脆弱部間に、凸状の入込防止片が設けられていることを特徴とする封印装置に存する。
【００１８】
請求項４記載の発明によれば、凸状の入込防止片が、被破壊部の筐体側の面と相対する面上であって、かつ左右脆弱間に設けられている。以上の構成によれば、封印を解除するためにマイナスドライバー等で、被破壊部の筐体側の面と相対する面上を押したとき、マイナスドライバーが、凸状の入込防止片と当接して、筐体側内部に入り込むことを防止することができる。
【００１９】
請求項５記載の発明は、請求項１〜４何れか１項記載の封印装置であって、前記被破壊部は、前記筐体側の面であって、前記左右脆弱部上に、凸状の破壊停止片が設けられていることを特徴とする封印装置に存する。
【００２０】
請求項５記載の発明によれば、凸状の破壊停止片が、被破壊部の筐体側の面であって、かつ左右脆弱部上に設けられている。以上の構成によれば、左右脆弱部のせん断破壊が、その左右脆弱部上に設けられた凸状の破壊停止片で停止する。従って、左右脆弱部が破壊停止片まで破壊した状態で、左右脆弱部間の被破壊部に連接された係合部が筐体内部の対象機器と接しないようにすれば、対象機器が傷つくことがない。
【００２１】
請求項６記載の発明は、請求項１〜５何れか１項記載の封印装置であって、前記被破壊部は、前記筐体側の面と相対する面に貼付される封印シール周縁の少なくとも一部に、凸状の剥がれ防止片が設けられていることを特徴とする封印装置に存する。
【００２２】
請求項６記載の発明によれば、凸状の剥がれ防止片が、被破壊部の筐体側の面と相対する面に貼付される封印シール周縁の少なくとも一部に、設けられている。従って、封印シールを被破壊部の筐体側と相対する面に貼付したとき、剥がれ防止片によって封印シールを剥がしにくくすることができる。
【００２３】
請求項７記載の発明は、筐体の内面上に搭載して収容された対象機器と対向して前記筐体に設けられた開口部を覆う被破壊部と、該被破壊部に連接されて前記開口部を通して該筐体内に挿入される係合部と、該係合部に設けられて前記筐体の開口部内周と係合する係合手段と、を備えた封印部材であって、前記被破壊部が、前記係合手段と係合する前記筐体の開口部内周側の端部から前記係合手段の係合解除方向に沿って延在して設けられ、かつ前記係合部を挟んで設けられた左右脆弱部を有していることを特徴とする封印部材に存する。
【００２４】
請求項７記載の発明によれば、封印部材が、筐体の内面上に搭載して収容された対象機器と対向して前記筐体に設けられた開口部を覆う被破壊部、該被破壊部に連接されて開口部を通して該筐体内に挿入される係合部及び該係合部に設けられて筐体の開口部内周と係合する係合手段を有している。さらに、封印部材の被破壊部において、左右脆弱部が、係合手段と係合する筐体の開口部内周側の端部から係合手段の係合解除方向に沿って延在して設けられ、かつ係合部を挟んで設けられている。以上の構成により、筐体と係合手段とをこすりあわせることなく、筐体との係合を解除することができる。
【００２５】
請求項８記載の発明は、筐体の内面上に搭載して収容された対象機器と対向して前記筐体に設けられた開口部を覆う被破壊部と、該被破壊部に連接されて前記開口部を通して該筐体内に挿入される係合部と、該係合部に設けられて前記筐体の開口部内周と係合する係合手段と、を備えた封印部材であって、前記被破壊部が、前記係合手段の係合解除方向に沿って延在して設けられ、かつ前記係合部を挟んで設けられた左右脆弱部と、前記係合手段側の前記左右脆弱部間を結ぶ脆弱部とを有していることを特徴とする封印部材に存する。
【００２６】
請求項８記載の発明によれば、封印部材が、筐体の内面上に搭載して収容された対象機器と対向して前記筐体に設けられた開口部を覆う被破壊部、該被破壊部に連接されて開口部を通して該筐体内に挿入される係合部及び該係合部に設けられて筐体の開口部内周と係合する係合手段を有する。さらに、封印部材の被破壊部が、係合手段の係合解除方向に沿って延在して設けられ、かつ係合部を挟んで設けられた左右脆弱部と、係合手段側の左右脆弱部間を結ぶ脆弱部とを有する。以上の構成により、筐体と係合手段とをこすりあわせることなく、筐体との係合を解除することができる。
【００２７】
【発明の実施の形態】
以下、この発明の一実施の形態を図面を参照して説明する。
図１及び図２は、本発明の封印部材の一実施の形態である封印蓋を示す斜視図及び天面図である。同図において、封印蓋１０は、被破壊部１１と、該被破壊部１１から懸垂して連接された係合部１２及び１３とから構成されている。この係合部１２及び１３には、矢印Ｙａ及びＹｂ方向に向かって延びる係合爪１２ａ及び１３ａ（＝係合手段）が各々設けられている。
【００２８】
被破壊部１１には、他の部分より脆弱な２つの左右破壊溝１１Ｌ及び１１Ｒ（＝左右脆弱部）が設けられている。この左右破壊溝１１Ｌ及び１１Ｒは、係合部１２を中心とした係合爪１２ａ側、すなわち矢印Ｙａ側の端部１１ａから、係合部１２との連接部分１１ｂ（図２参照）を挟んで延在している。
【００２９】
また、被破壊部１１の表面側（すなわち、メータケース２０側の面と相対する面）には、左右破壊溝１１Ｌ及び１１Ｒ間の端部１１ａに沿って、凸状の入込防止リブ１１ｃ（＝入込防止片）が設けられている。一方、被破壊部１１の裏面側（すなわち、メータケース２０側の面）には、左右破壊溝１１Ｌ及び１１Ｒ上に、凸状の破壊停止リブ１１ｄ（＝破壊停止片）が設けられている。
【００３０】
なお、図１中引用符号１１ｅは、被破壊部１１の表面側に貼付される封印シール（図示せず）の剥がれ防止のために設けられた凸状の剥がれ防止リブ（＝剥がれ防止片）である。この剥がれ防止リブ１１ｅにより、不正に封印シールの張り替えが行われることを防止している。
【００３１】
図３は、例えばタクシーの料金演算を行うための制御基板等を有するタクシーメータ（＝対象機器）を収納する筐体のメータケース２０の部分斜視図である。メータケースは、略長方形の開口部２１を有し、該開口部２１内には、前記封印蓋１０の係合爪１２ａ及び１３ａと係合する凸部２２及び２３が設けられている。また、メータケース２０には、封印蓋１０と係合した状態で、左破壊溝１１Ｌ及び右破壊溝１１Ｒを各々中心とした左右破壊溝間１１ｆ（図１参照）と反対側の被破壊部１１である被支持部１１ｇを支持する支持部２４及び２５が設けられている。
【００３２】
以下、上述した構成のメータケース２０に封印蓋１０を封印する封印動作及び、その封印を解除するための封印解除動作について説明する。まず、最初に封印動作について説明する。タクシーメータ等が事業所で検定され合格すると、封印蓋１０の被破壊部１１の表面側に、事業所名などが記載された封印シール（図示せず）が貼付される。
【００３３】
そして、図４の封印装置の断面図に示すように、封印蓋１０の係合爪１２ａ及び１３ａを、開口部２１の凸部２２及び２３に係合させて、メータケース２０を封印蓋１０によって封印する。このとき、図５に示すように、メータケース２０に設けられた凸部２２及び２３により、被破壊部１１の側面が隠されるため、被破壊部１１の側面をペンチ等により引っ張ったりして、封印蓋１０による封印の解除を不正に行うことを防止している。
【００３４】
次に封印解除動作について説明する。まず、被破壊部１１の左右破壊溝間１１ｆを、例えばマイナスドライバー３０によって、メータケース２０側に押す。左右破壊溝間１１ｆがケース２０側に押されると、左右破壊溝１１Ｌ及び１１Ｒには、その左右破壊溝間１１ｆ側に、矢印Ｙｄ方向（図１参照）の力が加わる。
【００３５】
一方、被支持部１１ｇは、支持部２４及び２５により支持されている。従って、左右破壊溝１１Ｌ及び１１Ｒには、その被支持部１１ｇ側に、矢印Ｙｕ方向（図１参照）の力が加わる。これらの力により、他の部分により薄く、すなわち脆弱に形成された左右破壊溝１１Ｌ及び１１Ｒは、端部１１ａからせん断破壊する。
【００３６】
上述したように、被支持部１１ｇを支持する支持部２４及び２５をメータケース２０に設けることにより、支持部２４及び２５が左右破壊溝間１１ｆを押す力を受けて、矢印Ｙｕ方向の力となる。このため、左右破壊溝１１Ｌ及び１１Ｒを押す力が効果的に、左右破壊溝１１Ｌ及び１１Ｒのせん断破壊に使用され、容易に左右破壊溝１１Ｌ及び１１Ｒをせん断することができる。
【００３７】
また、左右破壊溝１１Ｌ及び１１Ｒのせん断破壊は、破壊停止リブ１１ｄまで進むと停止する。このとき、図６に示すように、左右破壊溝間１１ｆは、破壊停止リブ１１ｄを支点として、係合部１２を中心とした係合爪１２ａ側と反対側、すなわち矢印Ｙ１方向に曲げられる。この結果、係合爪１２ａと凸部２３との係合が解除される。
【００３８】
その後、封印蓋１０を矢印Ｙ２方向にずらして外せば、係合爪１３ａと凸部２２との係合が解除され、封印を解除することができる。このようにすれば、メータケース２０の凸部２２及び２３と、係合爪１２ａ及び１３ａとをこすりあわせることなく、メータケース２０との係合を解除することができるので、メータケース２０を傷つけずに、封印解除を行うことができる。
【００３９】
上述した破壊停止リブ１１ｄは、左右破壊溝１１Ｌ及び１１Ｒが、破壊停止リブ１１ｄまで破壊して、破壊停止リブ１１ｄを支点にして左右破壊溝間１１ｆが矢印Ｙ１方向に曲がった状態であっても、係合部１２がメータケース２０内部の制御基板４０等と接しない位置に設けられている。このようにすることにより、左右破壊溝１１Ｌ及び１１Ｒを矢印Ｙ１側に曲げても、制御基板４０等が傷つくことがない。
【００４０】
さらに、図６に示すように、凸状の入込防止リブ１１ｃは、マイナスドライバー３０と当接して、マイナスドライバー３０がメータケース２０内部に入り込むことを防止している。このため、ケース２０内部に収納された制御基板４０等を、マイナスドライバー３０により傷つけずに済む。
【００４１】
なお、上述した実施形態では、被破壊部１１に、矢印Ｙａ側の端部から、連接部分１１ｂを挟んで延在する左右破壊溝１１Ｌ及び、１１Ｒを設け、左右破壊溝１１Ｌ及び、１１Ｒをせん断破壊するこにより、係合爪１２ａの係合解除を行っていた。
【００４２】
しかしながら、例えば図７の封印蓋の天面図に示すように、被破壊部１１と係合部１２との連接部分１１ｂが被破壊部１１の端部１１ａに設けられいない場合は、連接部分１１ｂを挟んで、端部１１ａに向かって延在する左右破壊溝１１Ｌ及び１１Ｒと、係合部１２より矢印Ｙａ側の左右破壊溝間１１ｆを結ぶ破壊溝１１ｈを設けるようにしても良い。この場合、マイナスドライバーを使って、左右破壊溝１１Ｌ及び１１Ｒと、破壊溝１１ｈをせん断破壊すれば、上述した実施形態と同様に、係合爪１２ａの係合が解除される。
【００４３】
また、上述した実施の形態では、対象機器としてタクシーメータを例にして説明していたが、封印を行う必要のある対象機器であれば、これに限られるものでなく、例えばタコグラフや、ガスメータであってもよい。
【００４４】
さらに、上述した実施の形態では、被破壊部１１に溝を形成することにより、他の部分より脆弱な左右脆弱部を形成していたが、例えば、ミシン目を形成することにより左右脆弱部を形成するようにしても良い。
【００４５】
【発明の効果】
以上説明したように、請求項１、２、７及び８記載の発明によれば、筐体と係合手段とをこすりあわせることなく、筐体との係合を解除することができるので、筐体を傷つけずに、封印解除を行うことができる封印装置及び、この封印装置に用いられる封印部材を得ることができる。
【００４６】
請求項３記載の発明によれば、左右脆弱部間の破壊部を、例えばマイナスドライバー等により筐体側に押したとき、その力が左右脆弱部を中心とした左右脆弱間側と反対側の支持部により支持される。このため、押す力が効果的に、左右脆弱部のせん断破壊に使われるので、封印解除時の左右脆弱部のせん断破壊を容易に行える封印装置を得ることができる。
【００４７】
請求項４記載の発明によれば、封印を解除するためにマイナスドライバー等で、被破壊部の筐体側の面と相対する面上を押したとき、マイナスドライバーが、凸状の入込防止片と当接して、筐体側内部に入り込むことを防止することができるので、筐体内部に収納された対象機器を傷つけずに、封印解除を行うことができる封印装置を得ることができる。
【００４８】
請求項５記載の発明によれば、左右脆弱部が破壊停止片まで破壊した状態で、左右脆弱部間の被破壊部に連接された係合部が筐体内部の対象機器と接しないようにすれば、対象機器が傷つくことがないので、筐体内部に収納された対象機器を傷つけずに、封印解除を行うことができる封印装置を得ることができる。
【００４９】
請求項６記載の発明によれば、封印シールを被破壊部の筐体側と相対する面に貼付したとき、剥がれ防止片によって封印シールを剥がしにくくすることができるので、不正に封印シールが剥がされるのを防止することができる封印装置を得ることができる。

BACKGROUND OF THE INVENTION
The present invention relates to a sealing device and a sealing member, and more particularly, to a sealing device for sealing a taximeter or the like and a sealing member used in the sealing device.
[0002]
[Prior art]
Conventionally, taximeters shown in FIGS. 8 to 10 have been proposed as the above-described sealing device. FIG. 8 is a partial perspective view of a meter case 100 (= housing) that houses a taxi meter (= target device) equipped with a control board for performing taxi fare calculation. As shown in the figure, the meter case 100 has an opening 101 formed therein. A projecting portion 102 protrudes from the inner peripheral wall of the opening 101.
[0003]
FIG. 9 is a perspective view of a sealing member 200 that seals the meter case 100. As shown in the figure, the sealing member 200 is made of an elastic member, and a concave portion 201 that engages with a convex portion 102 protruding from the opening 101 of the meter case 100 is formed along the outer peripheral surface thereof. . And this sealing member 200 is comprised so that it may attach to the opening part 101 of the meter case 100 by engaging the recessed part 201 with the convex part 102 of the meter case 100, as shown in FIG. .
[0004]
Next, a procedure for releasing the sealing of the sealing member 200 attached to the meter case 100 will be described below. First, the top surface 202 of the sealing member 200 is pierced with, for example, a thousand sheets 300 having a sharp tip. Then, by prying the stirrer 300 with the top surface 202 pierced, the engagement between the convex portion 102 and the concave portion 201 is released, and the seal is released.
[0005]
As described above, if the top surface 202 of the sealing member 200 is not punctured and broken by the 300 sheets, the sealing can not be released, so that the control board or the like housed in the meter case 100 can be exchanged illegally. I am trying not to.
[0006]
[Problems to be solved by the invention]
However, the above-described sealing device releases the seal by forcibly pulling the sealing member 200 with the awl 300. For this reason, the wear of the convex portion 102 is repeated, and finally the meter case 100 may not be able to engage with the concave portion 201 of the sealing member 200 and the seal case 200 may be unable to be sealed. .
[0007]
In addition, when the sealing member 200 is forcibly squeezed by the stirrer 300, if the stirrer 300 is squeezed with the main body wall 103 as a fulcrum, there is a problem that the main body wall 103 is damaged. Furthermore, when the stirrer 300 is pierced too much, there is a problem that the control board 400 or the like inside the meter case 100 is damaged.
[0008]
Therefore, the present invention pays attention to the problems as described above, and is used for a sealing device that can release a seal without damaging the housing itself or a target device stored in the housing, and the sealing device. It is an object of the present invention to provide a sealing member.
[0009]
