Description

【０００１】
【発明の属する技術分野】
この発明は、コンベヤ用部材の取付構造に関し、さらに詳しくは、食品等を搬送するコンベヤに用いる部材の取付構造に関する。
【０００２】
【従来の技術】
従来、食品等を搬送するコンベア１００において、コンベヤ本体１０１を所定の高さに支える脚１０２を同コンベア本体１０１に対して移動可能に取り付ける方法としては、図１１にて示すもののように、コンベア本体１０１の左右両側に設けられるフレ−ム１０１ａの側面に沿って適宜な間隔を置いてネジ孔１０４ａを穿設し、適宜な位置に有るネジ孔１０４ａに合わせて、脚１０２の上端に設けた取付金具１０５をあてがい、上記ネジ孔１０４ａにネジ１０４ｂ挿通して締結する取付構造が一般的であった（図１２）。
上記したように左右の両フレ−ム１０１ａに穿設された多数のネジ孔１０４ａは、脚１０２の取付位置を必要に応じて変更するためのものである。例えば食品業界等では、加工ラインのレイアウトを頻繁に変更するため、その際に脚１０３の取付位置を任意に変更できることが重宝がられている。
【発明が解決しようとする課題】
【０００３】
しかしながら、最近において、ＨＡＣＣＰ（危害分析、重要管理点）による食品加工プロセス管理が浸透し、その手法を導入する企業が増加する中で、食品を搬送するコンベアもその管理の範囲に含まれるようになっている。
上記したＨＡＣＣＰの主旨によれば、図１１，１２にて示したコンベヤ１００のように、コンベア本体１０１の左右両フレ−ム１０１ａに沿って多数のネジ孔１０４ａが設けてある場合、このネジ孔１０４ａに汚物や雑菌が溜まり易くなるため、衛生的に好ましい構造とはいえない。
【０００４】
また、従来の食品用コンベアの中には、上記したコンベア１００にて用いた脚１０２を取り付けるためのネジ孔１０４ａが衛生的に好ましくないことを理由として、ステンレス板等からなるフレ−ムの側面部を２枚の板材により単に挟持してネジ止めすることにより、脚の支持を行なう構造のものが提案されている。
しかし、このような脚の支持構造は、板状のフレ−ム本体の側面部を２枚の取付板により挟持して締め付けただけのものであるため、左右の脚の位置を正確に定めることが出来ない上、脚の支持部に何らかの負荷が加わった場合に、２枚の取付板が横方向へ簡単に移動してしまったり、さらには、上記取付板がフレ−ムから抜け落ちてしまう可能性があった。
【０００５】
本発明が解決しようとする課題は、上記した如く特に食品を搬送するコンベアの本体を支える脚等の取付部材を同コンベア本体のフレ−ムに対してずれや抜け等の支障を生じることなく移動可能に支持すると共に、食品のカスや汚物、雑菌等の溜まり易い構造を合理的に回避し得るコンベア用部材の取付構造を提供することにある。
【０００６】
【課題を解決するための手段】
上記した課題を解決するために、本発明は、コンベヤ本体を構成するフレ−ムの全長方向にわたって略平板状の部材取付部を形成し、この部材取付部の全長方向に適宜な間隔をおいて配置した複数の取付位置に、略板状の取付部材を着脱可能に取り付ける構造であって、上記フレ−ムに形成した部材取付部の取付位置の表面と裏面とに、略板状の取付部材と当て板とをあてがい、これらの間にて上記フレ−ムの部材取付部の取付位置を挟持し、この取付位置の挟持範囲には、一方の面が所定形状に突出し、且つ他方の面が上記突出部分の形状と合致する形状に窪む主嵌合部を形成し、この主嵌合部をフレ−ムの部材取付部の各取付位置に形成し、上記取付部材及び当て板の少なくとも一方に、上記各主嵌合部と同形の従嵌合部を形成し、この取付部材及び当て板をフレ−ムの部材取付部の各取付位置に設けた主嵌合部の凸側及び凹側の一方若しくは双方に嵌係合し、且つ、上記フレ−ムの部材取付部の取付位置を挟持する取付部材と当て板とにおける挟持範囲から外れる部位の間を着脱可能な締め付け手段により締め付けて成るものである。
【０００７】
コンベア本体を構成する左右両フレ−ムの部材取付部には、その全長方向に適宜な間隔を置いて取付位置を配置してある。これらの各取付位置には、一方の面が所定形状に突出し、他方の面が上記突出部分の形状と合致する形状に窪む主嵌合部を形成してある。一方、フレ−ムに対して取付固定する取付部材と当て板の少なくとも一方には、上記主嵌合部と形状一致した状態で嵌合する従嵌合部が形成してある。尚、上記した取付部材とは、コンベアを支える脚等をフレ−ムの部材取付部の任意の取付位置に対して取付固定するものである。
上記した取付部材と当て板とを、上記部材取付部の取付位置の表面と裏面とにあてがい、同取付位置を挟持する形で装着する。この際、上記取付部材、及び当て板の少なくとも一方に設けた従嵌合部が、上記部材取付部の取付位置に形成した主嵌合部の凸側及び凹側と合致した状態で嵌合し、この嵌合構造により、取付部材と当て板とをフレームの部材取付部の取付位置に対してずれない様に位置決めすることができる。
【０００８】
そして、取付部材と当て板の挟持範囲から外れる部位を着脱可能な締め付け手段により締め付けることで、上記嵌合関係を保ちつつ、取付部材と当て板とがフレ−ムに対して強固に取付られる。また、フレ−ムの部材取付部に沿っては上記したような主嵌合部が複数個並んで配置してあるので、取付部材を移動する際には、締め付け手段を弛めて取り外すことにより、フレ−ム上の位置にある取付位置に取付部材を移動することができる。
【０００９】
請求項２記載の取付構造は、フレ−ムの部材取付部の各取付位置に、各々複数個の主嵌合部を形成すると共に、これら取付位置を挟持する取付部材及び当て板の少なくとも一方に、上記主嵌合部に対応して嵌係合する複数個の従嵌合部を形成してなるものである。
この場合、フレ−ムの部材取付部の取付位置に取付部材を取付固定する際に、取付部材及び当て板の少なくとも一方に設けた複数個の従嵌合部がフレ−ムの部材取付部の各取付位置に複数個ずつ設けられる主嵌合部に対応して嵌合する。このため、上記した如くフレ−ムを挟持する形で取り付けられる取付部材と当て板とが、複数個の主嵌合部と従嵌合部との嵌合関係を介してフレ−ムの部材取付部の取付位置に圧着されることになる。
【００１０】
【発明の施の形態】
以下、本発明の一実施例を図面に基づいて説明する。
図１乃至図４にて示すコンベアＡは、食品等を搬送するものである。尚、食品等を搬送するコンベアには、ベルトコンベアタイプやネット状のベルトを装備するネットコンベア等があるが、本実施例は、ネットコンベアタイプのものである。
ベルトコンベアＡのコンベア本体ａは、左右両側に沿って一対のフレーム１ａ，１ｂを配設し、該両フレーム１ａ，１ｂの間に連結材（図示せず）を横架することにより、同フレ−ム１ａ，１ｂの間が平面視において平行するように支持してある。
【００１１】
また、上記フレ−ム１ａ，１ｂの両端部には、左右一対となる折り返し用のスプロケット２ａ，２ｂを同軸上に設け、このスプロケット２ａ，２ｂ間にステンレス鋼線等を網組みして無端状の網ベルト３を架け渡してある。網ベルト３は、その左右両側縁部に沿って無端状のチェーン３ａを沿設し、この左右両チェーン３ａを上記スプロケット２ａ，２ｂ間に掛け回してある。
【００１２】
上記網ベルトは、左右の両チェーン３ａをフレ−ム１ａ，１ｂ内側の上縁（往路側）に沿って直線的にスライドするようにガイドしてある。これにより、網ベルト３は、フレ−ム１ａ，１ｂの往路側にて水平に保持され、食品等を載せて搬送する搬送面ａ１を構成する。また、上記フレ−ム１ａ，１ｂの下流側の一側部には、駆動モータ４ａを具備する駆動機構４を設け、この駆動機構４により上記下流側のスプロケット２ｂを回転駆動するように構成してある（図１）。
上記したように構成したコンベア本体ａは、両端よりの左右両側部には脚５を各々取り付け、合計４本の脚５により所定の高さにて水平状態に自立せしめている。
【００１３】
コンベア本体ａ両側のフレ−ム１ａ，１ｂは、帯状のステンレス鋼板等を断面略Ｌ形に折り曲げ成形し、各々のフレ−ム側面に沿って板状の部材取付部１ｃを形成してある。そして、フレ−ム１ａ，１ｂの側面部を構成する部材取付部１ｃに沿っては、定間隔を置いて円形の主嵌合部６を並設してある（図３）。主嵌合部６は、プレス成形、所謂エンボス加工することにより、フレ−ム１ａ，１ｂの部材取付部１ｃの表面が円形に窪み、裏面が円形に突出するように形成してある。本実施例の主嵌合部６の場合、外形を円形にした窪み６ｂを凹設してある（図４）。また、上記した主嵌合部６を設けた各箇所は、それぞれ後述する取付部材７の取付位置ｃとなる。上記主嵌合部６の窪み６ｂの内面は外周部を除く部分を平面状に形成してある。
【００１４】
一方、主嵌合部６の裏面、即ち凸部６ａは、上記窪み６ｂを形成すると同時に押し出されて形成される。即ち、凸部６ａの外形は、上記窪み６ｂの内部と略形状一致する状態で嵌合するようになっている。尚、上記した凸部６ａ及び６ｂの外周部位は、これらがガタつくことなく嵌係合するように、適宜なテーパーと丸みを設けてある。尚、上記主嵌合部６同士の間隔及び設置位置は、左右のフレ−ム１ａ，１ｂの間で一致するように設定してある。換言すると、各取付位置ｃは左右のフレ−ム１ａ，１ｂの間で一致する。
【００１５】
一方、各脚５の上端には取付部材７を取付固定してある。取付部材７は、比較的肉厚のステンレス鋼板を用いて形成し、その下端側を脚５の上端部に溶接もしくはネジ止め等により取付固定する。また、取付部材７の中間部には止めネジ９ｂを挿通するネジ孔９ａを２個並べて穿設してある。
図４にて示すように、上記取付部材７を装着する取付位置ｃの裏面側には、当て板１０をあてがってある。上記当て板１０は、上述した取付部材７との間にフレ−ム１ａ，１ｂの取付位置ｃを挟持するものであり、上記取付部材７の両ネジ孔９ａの下部から上の範囲をカバーできる程度の板材として形成してある。
【００１６】
当て板１０の下部には、上記取付部材７の両ネジ孔９ａと重なり合うネジ孔１０ａを穿設する。また、同当て板１０の上部寄りの中央には、上記取付部材７に設けた主嵌合部６と嵌合する従嵌合部８を形成してある。従嵌合部８は取付部材７に設けた主嵌合部６と形状一致した状態で嵌合するように全く同形な凸部８ａと窪み８ｂを形成してあり、同従嵌合部８の窪み８ｂを取付部７の主嵌合部６の凸部に重ね合わせるように嵌合した状態において、上記両ネジ孔１０ａと取付部材７のネジ孔９ａとが一致するように構成してある（図４）。また、上記両ネジ孔１０ａ，９ａとの間にはフレ−ム１ａ，１ｂと略同じ厚さのスペーサー１１を介在する。このスペーサー１１には、上記両ネジ孔１０ａ，９０ａと同じ間隔にて通孔１１ａを穿設してある。
【００１７】
上記した当て板１０は、脚５上部の取付部材７を任意の取付位置ｃに表側からあてがった状態を維持しつつ、同取付位置ｃの裏面側にあてて取付位置ｃの主嵌合部６と従嵌合部８とを重ね合わせて嵌係合する。そして、当て板１０の下部と取付部材７との間にスペーサー１１を挿入した状態で各部材を重ね合わせ、重なり合ったネジ孔９ａ，１０ａ，１１ａに止めネジ９ｂを挿入し、裏側に突出したネジ先端部にナット９ｃを螺合して締め付ける。
【００１８】
上記したように、取付部材７と当て板１０とにより、フレ−ム１ａ，１ｂの取付位置ｃを挟むように重ね合わせて止めネジ９ｂを締め付けると、主従両嵌合部６，８が嵌係合した状態を維持しつつ、取付部材７と当て板１０とによって、フレ−ム１ａ，１ｂの取付位置ｃの挟持範囲ｄを強固に挟持する(図３)。これにより、脚５上部の取付部材７をフレ−ム１ａ，１ｂの所望する取付位置ｃに対して強固に取付固定することができ、従来のもののように取付部材がずれたり、抜けたりする不具合も解消できる。
尚、上記した主従両嵌合部６，８は、上記した挟持範囲ｄの略中央に形成し、また、止めネジ９ｂを挿通するネジ孔９ａ，１０ａは、上記挟持範囲ｄの範囲外に穿設する。本実施例のネジ孔９ａ，１０ａは、フレ−ム１ａ，１ｂの取付位置ｃにおける下端縁の直ぐ下に穿設し、両止めネジ９ｂによる締め付け力が上記挟持範囲ｄを効果的に締め付けるようにしてある。
【００１９】
前記したように、フレ−ム１ａ，１ｂに沿っては、主嵌合部を複数個並べて配置してあるので、脚５の取付位置を変更したい場合には、上記止めネジ９ｂ及びナット９ｃを弛めることにより、それまで使用していた取付位置ｃから取付部材７と当て板１０を取り外すか、嵌合部６，８の凹凸がはずれる程度まで緩めて、新たな取付位置ｃに上記した要領で取付部材７と当て板１０を移して取付ければよい。
【００２０】
次に、図５にて示す実施例について説明する。
上述した実施例では、止めネジ９ｂを挿通する部位に生じる間隙にスペーサー１１を介在した状態で取付部材７と当て板１０とを締め付けていた。
図５にて示す実施例では、上記止めネジ９ｂを挿通する部位と、挟持範囲ｄとの境界部を断面クランク状に屈曲することにより、当て板１０における止めネジ９ｂを挿通する部位を取付部材７の内面に直接的に接触した状態にて止めネジ９ｂを締め付けるように構成してある。上記した取付構造においては、取付部材と当て板との間に介在させるスペーサーを省略することができる。
【００２１】
図６にて示した実施例は、当て板２１０の一側を横方向へ延長することにより、同当て板２１０の幅の中に２個の従嵌合部を形成したものである。この取付構造は、装着状態において、上記当て板２１０に設けた２個の従嵌合部（図示せず）が、フレ−ム１ａ，１ｂの取付位置ｃにて定間隔を置いて並ぶ２個の主嵌合部６に嵌係合した状態で当て板２１０と取付部材７を締め付けることができる。この取付構造により、取付部材７の回転方向のがた付きを防止し、フレ−ム１ａ，１ｂに対して脚５を確実に取付固定できる。
【００２２】
図７(ａ)にて示した実施例は、原動機やスイッチ等（図示せず）を取付支持する比較的大きな取付部材２０７をフレ−ム１ａ，１ｂに対して取付固定する構造であって、フレ−ム１ａ，１ｂの部材取付部１ｃの３カ所の取付位置ｃにわたって被嵌する取付部材２０７を具備する。上記取付部材２０７に対応する当て板２１０は、３個の従嵌合部（図示せず）を前記したものと同様に所定の間隔を置いて並設してある。
図７（ｂ）は、上記した取付部材２０７を利用して駆動機構２０７ａを設置する場合を示し、上記取付部材２０７と、別の取付部材２０７'とを２枚並べた状態でフレ−ム１ａ，１ｂに取付固定し、これら両取付部材２０７，２０７'を利用して、上記駆動機構２０７ａを設置してある。
上記取付部材２０７，２０７'をフレ−ム１ａ，１ｂに取り付け固定する際には、当て板２１０の各従嵌合部をフレ−ム１ａ，１ｂの各取り付け位置ｃに形成した主嵌合部６に嵌係合し、上記当て板２１０とフレ−ム１ａ，１ｂとの挟持範囲ｄの直下に４本の止めネジ９ｂを挿通して締め付けてある。上記したように本発明の取り付け構造は、脚の取付部材に限定するものではなく、上記した取付部材２０７のように、原動機やスイッチ類等を取付支持する部材に応用してもよい。
【００２３】
次に図８にて示す実施例について説明する。この取付構造は、脚５の上端部に取付固定した取付部材３０７と対面する当て板３１０の上部に、比較的小径な従嵌合部８'を所定の間隔を置いて設けたものである。また、フレ−ム１ａ，１ｂの部材取付部１ｃには、上記した従嵌合部８'と同形な主嵌合部６'を上記従嵌合部８'と同じ間隔で形成してある。上記したように、本発明の主従両嵌合部６'，８'は、略半球形にエンボス加工してあり、取付部材３０７と当て板３１０とによりフレ−ム１ａ，１ｂの部材取付部１ｃを挟持する際に、上記主嵌合部６'の凸部６ａ'が当て板３１０に形成した従嵌合部８'の窪み８ｂ'内に合致した状態で嵌係合するように構成してある。また、上記取付構造において、フレ−ム１ａ，１ｂの部材取付部１ｃに沿って形成する主嵌合部６'の間隔を上記当て板３１０の従嵌合部８'の間隔と一致させることは言うまでもない。
【００２４】
尚、上述した各実施例においては、フレ−ム１ａ，１ｂの部材取付部１ｃと当て板とに主嵌合部と従嵌合部とを形成し、フレ−ム１ａ，１ｂに取付部材を取付固定する際に、上記主嵌合部と従嵌合部とを嵌係合するように構成した。
しかし、本発明は、図９にて示すように、フレ−ム１ａ，１ｂの部材取付部１ｃに主嵌合部４０６を形成すると共に、当て板４１０に従嵌合部４０８を形成し、さらに、取付部材４０７に上記従嵌合部４０６と同形な従嵌合部４０７'を形成し、これら主従３個の嵌合部４０６，４０８，４０７'を三重に重ね合わせて嵌係合した状態で止めネジ９ｂにより締め付けることにより、フレ−ム１ａ，１ｂに対する取付部材４０７の固定をより強固に行なうことができ、取付部材４０７の横移動も効果的に防止し得る。
【００２５】
また、上記した各実施例では、主従両嵌合部をフレ−ム１ａ，１ｂの外側から内側へ向けて突出するように形成したが、主従両嵌合部は、図１０にて示すように、縦嵌合部５０８，５０６，５０７'がフレ−ム１ａ，１ｂの内側から外側へ向けて突出するように形成してもよい。さらに、上記した各実施例では、主従両嵌合部を円形若しくは半球形に形成した。しかし、主従両嵌合部は、形状一致した状態で嵌合する形状であれば形状や大きさを限定するものではなく、円形や半球形以外の形状、例えば各角部を幾分丸めて形成した四角形や六角形等に形成してもよい（図示せず）。
さらに、上記各実施例は、フレ−ムの取付位置を挟持する取付部材と当て板とにおける挟持範囲から外れる部位の間を締め付ける締め付け手段としてネジの螺合を用いたが、本発明にて用いる締め付け手段は、ネジの螺合関係に限定するものではなく、取付部材と当て板との間を着脱可能に締め付けることができれば既存のどのような締め付け手段をもちいてもよい。例えばクランプ金具やスプリングを用いた挟持金具、リベット等を使用してもよい。
【００２６】
【発明の効果】
本発明は以上説明したように、コンベア本体を構成するフレ−ムの部材取付部に適宜間隔を置いて取付位置を配置し、これらの取付位置に、一方の面が所定形状に突出し、他方の面が上記突出部分の形状と合致する形状に窪む主嵌合部を形成してある。また、取付部材と当て板の少なくとも一方には、上記主嵌合部と嵌合する従嵌合部が形成してある。よって、上記取付部材と当て板とによりフレ−ムの取付位置の表裏両面から挟持すると、取付部材、及び当て板の少なくとも一方に設けた従嵌合部は取付部に形成した主嵌合部の凸側若しくは凹側と合致した状態で嵌係合する。そして、この嵌合関係に基づいて、脚取付部材等の取付部材をフレ−ムの取付位置に対して正確に位置決めすることができる。
【００２７】
また、取付部材と当て板とは、フレ−ム取付位置の挟持範囲から外れる部位を着脱可能な締め付け手段、例えばネジ等により締め付けることで、上記した主従両嵌合部の嵌合関係を保ちつつ、取付部材と当て板とによって、フレ−ムの被嵌合部を強固に挟持する。これにより、取付部材がずれたり、抜けたりする不具合を防止すると共に、同取付部材と当て板とをフレ−ム上における所望の取付位置に対して確実に取付固定することができる。
さらに、上記したフレ−ムに沿っては、主嵌合部を複数個並べて配置してあるので、取付部材を移動する際には、ネジ等の締め付け手段を弛めて取り外すことにより、フレ−ム上にある任意の取付位置に取付部材と当て板を移動し、上記した要領で取付固定することが可能である。
【００２８】
また、フレ−ムの取付位置と取付部材及び当て板の位置決めとして、主嵌合部と従嵌合部との嵌係合を利用しているので、上記した如く取付部材の取付を正確に設定し得ると共に、従来の食品用コンベアのように、フレ−ムに沿って多数のネジ孔を開ける必要がなくなり、これにより、食品のカスや汚物、雑菌等がネジ孔に溜まってコンベアが不衛生になる不具合を回避し得る。
さらに、フレ−ムの取付位置を挟持する取付部材と当て板とは、フレ−ムの取付位置を挟持する挟持範囲から外れる位置を利用して締め付けているので、例えば締め付け手段としてネジを使用した場合でも、フレ−ムに沿って位置決め用のネジ孔を多数穿設する必要がなくなるので、上述したように、フレ−ムに開けたネジ孔に食品のカスや雑菌等が溜まって不衛生になることを防止し得る。
また、取付け手段としてネジを使用した場合、そのネジを全て取り外さなくとも取付部材を移動させることができるので、脚等の位置変更を速やかにできる。
【００２９】
請求項２記載の取付構造は、上記フレ−ムの部材取付部に適宜間隔を置いて配置した各取付位置に、各々複数個の主嵌合部を形成すると共に、これら取付位置を挟持する取付部材及び当て板の少なくとも一方に、上記主嵌合部に対応して嵌係合する複数個の従嵌合部を形成して成る。
よって、フレ−ムの取付位置に取付部材を取付固定する際に、複数の主嵌合部と、従嵌合部とが嵌合した状態で締め付けることができるので、上記嵌合関係による位置決め機能や、ずれ防止機能をより一層向上することができる。

BACKGROUND OF THE INVENTION
The present invention relates to an attachment structure for a conveyor member, and more particularly to an attachment structure for a member used in a conveyor for conveying food or the like.
[0002]
[Prior art]
Conventionally, in a conveyor 100 for transporting food or the like, as a method for movably attaching a leg 102 that supports the conveyor body 101 to a predetermined height, as shown in FIG. The screw holes 104a are formed at appropriate intervals along the side surfaces of the frame 101a provided on the left and right sides of the 101, and the mounting provided on the upper end of the leg 102 in accordance with the screw holes 104a at appropriate positions. A mounting structure in which the metal fitting 105 is applied and the screw 104b is inserted into the screw hole 104a and fastened is generally used (FIG. 12).
As described above, the numerous screw holes 104a drilled in the left and right frames 101a are for changing the mounting position of the legs 102 as necessary. For example, in the food industry and the like, since the layout of the processing line is frequently changed, it is useful that the attachment position of the leg 103 can be arbitrarily changed at that time.
[Problems to be solved by the invention]
[0003]
However, recently, as food processing process management by HACCP (hazard analysis, critical control point) has permeated and the number of companies introducing the method has increased, conveyors that transport food are also included in the scope of management. It has become.
According to the gist of the HACCP described above, when a large number of screw holes 104a are provided along the left and right frames 101a of the conveyor body 101 as in the conveyor 100 shown in FIGS. Since filth and germs easily accumulate in 104a, it cannot be said to be a hygienic preferred structure.
[0004]
Moreover, in the conventional food conveyor, the side surface of the frame made of a stainless steel plate or the like because the screw hole 104a for attaching the leg 102 used in the conveyor 100 is not hygienic. There has been proposed a structure in which a leg is supported by simply sandwiching a part between two plate members and screwing the part.
However, such a leg support structure is simply a structure in which the side portion of the plate-shaped frame body is sandwiched and tightened by two mounting plates, so that the positions of the left and right legs are accurately determined. In addition, when some load is applied to the leg support, the two mounting plates can easily move in the horizontal direction, and the mounting plate can fall out of the frame. There was sex.
[0005]
As described above, the problem to be solved by the present invention is to move a mounting member such as a leg that supports a main body of a conveyor that conveys food without causing any troubles such as displacement and disconnection with respect to the frame of the main body of the conveyor. An object of the present invention is to provide a conveyor member mounting structure capable of supporting such a structure and rationally avoiding a structure in which food residue, dirt, germs, and the like easily accumulate.
[0006]
[Means for Solving the Problems]
