Description

【０００１】
【発明の属する技術分野】
本発明は、無数の連続気孔を有する多孔質体よりなる印字体を備えた連続捺印可能な印判であって、更に詳しくは、捺印動作と連動して回動する蓋体を一体的に備えた印判に関するものである。
【０００２】
【従来の技術】
従来より、多孔質体からなる印字体にインキを含浸させた連続捺印可能な印判は広く知られている。この種の印判は通常、未使用時においては印面を閉塞状態とするための印面キャップを装着して、印面にゴミや傷がついたり、印面から滲み出るインキにより他物が汚れるのを防止している。そして、使用時には印面キャップを取り外して捺印し、捺印を終えたら再度印面キャップを装着していたが、この印面キャップの着脱作業は使用者にとっては非常に煩わしいものであり、印面キャップを紛失してしまう恐れもあった。
【０００３】
そこで、このような問題を解決した印判として、例えば実公昭５３−４４４８８号に開示されたものがある。この印判は、脚枠体の外周を上方より覆う外枠体を下方に押圧することにより、前記外枠体と連結されて前記脚枠体内に配設された印判主体が下降し、それに連動して前記脚枠体に枢着された蓋体が回動して、前記印判主体の下端に設けられた印字体の印面が開放状態となるもので、これにより捺印することができる。一方、捺印終了後は前記外枠体への押圧を解くことにより、前記外枠体と前記脚枠体の間に配設された弾発部材の弾発力により前記外枠体と前記印判主体が上昇し、それに連動して前記蓋体が開蓋時と逆方向に回動して印面を閉塞するものである。このように、一連の捺印動作と連動して回動する蓋体を一体的に備えた印判は、蓋体が分離不可能となっているので別体の印面キャップを着脱する印判のように印面キャップを紛失する恐れはなく、使用時における印面キャップの着脱作業も不要である。又、蓋体が外れる心配もないので、携帯にも便利である。
【０００４】
【発明が解決しようとする課題】
ところが、前記したような従来の蓋体を一体的に備えた印判は、捺印のたびに蓋体が回動して開閉するために素早い連続捺印がしにくく、伝票などに連続的に捺印する際には非常に不便であった。
【０００５】
又、前記したような従来の蓋体を一体的に備えた印判は印判主体を容易に着脱できる構成ではなく、印判全体を分解しなければ印判主体を取外すことはできなかった。このため、例えば、印字体の老朽化や印面に傷がついたことより鮮明捺印ができなくなるというような、印判主体だけを新品に交換すれば解消できるような不具合が起きたとしても、使用者は印判主体を取外して交換することは困難なので同種の印判を再度購入するしかなく、このことは使用者にとって不都合な点となっていた。
【０００６】
更に、従来の蓋体を一体的に備えた印判に組み付けられている印判主体は、通常、蓋体を一体的に備えた印判専用に設計されたものであったため、他の種類の印判に組み付けられる印判主体を蓋体を一体的に備えた印判に流用したり、蓋体を一体的に備えた印判に組み付けられる印判主体を他の種類の印判に流用することができず、部品の共通化が図れなかった。
【０００７】
そこで、本発明は前記した不具合を解消して、素早い連続捺印がしやすく、又、使用者が印判主体の着脱を容易に行えるようにして、印判主体を他の種類の印判に組み付けられるものと共通化できるようにした蓋体を一体的に備えた印判を提供することを目的とする。
【０００８】
【課題を解決するための手段】
本発明は前記課題を解決するために、上下端面が開口し側面に窓部２を有する脚枠体１と、前記脚枠体１内に昇降自在に設けられる内装体４と、前記脚枠体１の外周を上方より覆い前記内装体４と連動して昇降する外枠体２３と、前記内装体４の下端に着脱自在に取付けられ下端に印字体１３を備えてなる印判主体１２と、前記脚枠体１の窓部２側に枢着され前記内装体４の昇降に連動して回動する蓋体１７と、前記内装体４を常時上方に付勢して前記印字体１３の印面を前記脚枠体１の下端開口より上方に位置させて前記蓋体１７を閉蓋状態とする弾発部材３２とを備えた印判において、前記内装体４の上部を中空状の筒部７として、前記外枠体２３の上部に前記筒部７内に収まるカム部３９Ａを有する偏心カム３９を回転自在に設け、前記筒部７の一側に前記カム部３９Ａが常時当接する弾性フック片３３を設け、前記内装体４を下降させて前記蓋体１７が開蓋状態にある時に前記偏心カム３９を回転させると、前記弾性フック片３３が外方に撓んで前記脚枠体１の上端内面１Ａと係合し、前記内装体４を上昇不可能にロックすることを特徴とする印判である。
【０００９】
又、前記偏心カム３９に上下方向に貫通する貫通孔４１を設け、該貫通孔４１に下端が前記印判主体１２の上面に当接する押し棒４５を昇降自在に設け、この押し棒４５を下降させると印判主体１２が下方に押し出されるようにする。
【００１０】
【発明の実施の形態】
以下、本発明の好ましい一実施の形態を図１〜図７にて詳細に説明する。１は上下端面が開口した円筒状をしたプラスチック製の脚枠体で、側面には後述する蓋体１７の側板部１８と形状が合致する窓部２を設けてあり、該窓部２の開口縁対向位置には一対の軸受部３、３を設けてある。
【００１１】
４はプラスチック製の内装体で、下端に印字体１３を備えた印判主体１２が着脱自在に取付けられる円形の印判取付部５と、印判取付部５の上端に対向して設けられる一対の側壁部６、６と、側壁部６、６の上端に設けられ上下端面が開口した円形中空状の筒部７とからなる。そして、印判取付部５の上端面中央には円形の貫通孔８を設けてあり、側壁部６、６の対向位置には該側壁部6の中間よりやや上方を上端９Ａとして、該上端９Ａから側壁部６の下方角部近傍の下端９Ｂまで下方に緩やかに湾曲して延びる略ノ字状の一対の案内孔９、９を設けてある。又、筒部７の一側面には該筒部７を断面Ｃ字状とする切欠部１０を設けてあり、筒部７の側面上方対向位置には一対の係止孔１１、１１を設けてある。
【００１２】
尚、本実施の形態では、切欠部１０は側壁部６、６の２点間の中間に位置する部分に設けてあり、係止孔１１、１１は側壁部６、６と同側に設けてあるが、切欠部１０を設ける位置は特に限定されるものではない。又、係止孔１１、１１も一対とすることに限定されるものではなく、例えば、筒部７の側面に切欠部１０を避けて周方向に９０°間隔で３ヶ所に設けても良い。
【００１３】
この内装体４は、筒部７を上向きにして側壁部６、６間に形成された空間と脚枠体１の窓部２が連通状態となり、かつ、案内孔９、９の下端９Ｂ、９Ｂが窓部２側に向くようにして脚枠体１内に昇降自在に設けてあり、筒部７は脚枠体１の上端開口より突出して、脚枠体１の上端開口内で昇降自在となっている。そして、図２に示すように脚枠体１の上端内面１Ａと側壁部６、６の上端が当接した時、内装体４は脚枠体１内の最上部に位置することとなり、この時、印判取付部５に装着された印判主体１２の印字体１３の印面は脚枠体1の下端開口より上方に位置するものとしている。
【００１４】
印判主体１２は、連続気孔を有する多孔質ゴムよりなる印字体１３と該印字体１３の上面に接触する図示しないインキ吸蔵体を主筒部１４の下方で受金１５により保持してなり、下端には印字体１３の印面が露呈している。又、主筒部１４の上方には前記インキ吸蔵体にインキを供給するための図示しないインキカートリッジを着脱自在に取付けてあり、主筒部１４の上端にはそのインキカートリッジの着脱を行うための摘み部１６が露呈している。この印判主体１２は印面を下向きにして摘み部１６の上面が印判取付部５の上端内面に当接するように印判取付部５内に圧入嵌合により着脱自在に取付けられている。このような構成の印判主体１２は、例えば、公知の連続捺印可能な印判や筆記具後端に印判を備えた印判付筆記具等に組み付けられる印判主体（例えば、特開平９−３９３５３号や特開平１０−１７５３５９号に開示された印判部３）をそのまま流用することができる。
【００１５】
１７はプラスチック製の蓋体で、脚枠体１の窓部２に合致する形状の側板部１８と、該側板部１８の下部内側面に設けられた円形の閉塞部１９と、側板部１８の上部で二股状に分かれて内側に屈曲した一対の連結部２０、２０とからなる。そして、側板部１８の側縁には脚枠体１の一対の軸受部３、３に対応する一対の軸２１、２１を設けてあり、連結部２０、２０の側縁には前記軸２１、２１と同方向に突出する一対の案内突起２２、２２を設けてある。
【００１６】
この蓋体１７は、脚枠体１内に内装体４が配設された状態で窓部２側から連結部２０、２０を側壁部６、６間の空間に挿入し、案内突起２２、２２を案内孔９、９に内側より嵌入して、更に軸２１、２１を軸受部３、３に位置させた状態で、内装体４と連結される。尚、案内突起２２、２２を案内孔９、９に嵌入する時、連結部２０、２０は二股状となっているため内側に撓むことができるので、この作業はスムーズに行うことができる。
【００１７】
そして、図２に示すように内装体４が脚枠体１内の最上部に位置する時、案内突起２２、２２は案内孔９、９の下端９Ｂ、９Ｂに位置するものとしており、この時、蓋体１７は閉蓋状態となって、側板部１８は窓部２を閉塞し、閉塞部１９は印字体１３の印面を閉塞するものである。
【００１８】
２３は下端面が開口した円筒状をしたプラスチック製の外枠体で、脚枠体１よりも大径のものである。そして、外枠体２３の上端中央には凹部２４を設けてあり、外枠体２３の上端内部であって凹部２４の外周には環状溝２５が形成されている。又、図６に示すように凹部２４の底面２６の中央には開口部２７を設けてあり、底面２６の外周縁には内装体４の筒部７に設けた一対の係止孔１１、１１に対応する一対の係止爪２８、２８を垂下して設けてある。更に、外枠体２３の側面には蓋体１７の側板部１８が出没可能な大きさの切欠部２９を設けてあり、該切欠部２９の上方開口縁対向位置には一対のレール３０、３０を、切欠部２９の上端開口縁には突起３１をそれぞれ設けてある。
【００１９】
この外枠体２３は、脚枠体１の上端外面と外枠体２３の環状溝２５の間に弾発部材３２を介在させた状態で内装体４と連結されるもので、脚枠体１の上方外周で内装体４と連動して昇降するものである。尚、本実施の形態では、弾発部材３２としてコイルスプリングを使用している。そして、外枠体２３の組み付けは、まず、外枠体２３の環状溝２５に弾発部材３２の一端を支持させ、一方で、脚枠体１内の内装体４を最上部に位置させて脚枠体１の上端開口より筒部７を完全に突出させる。その状態で、外枠体２３の下端開口より筒部７を挿入し、外枠体２３の一対の係止爪２８、２８を筒部７の一対の係止孔１１、１１に係止させる。この時、側板部１８が切欠部２９と同位置になるように位置合わせをする。これにより、外枠体２３は脚枠体１の上方外周を覆った状態で内装体４と連結され、筒部７の突出量に対応して脚枠体１の外周で昇降自在となる。尚、外枠体２３を内装体４に連結させる際、筒部７の上端面と外枠体２３の底面２６の当接部分に接着剤を着けることにより、外枠体２３と内装体４の連結状態をより強固なものとすることができる。
【００２０】
そして、外枠体２３を内装体４に連結させた時、一端が環状溝２５にて支持された弾発部材３２の他端が脚枠体１の上端外面にて支持され、外枠体２３は弾発部材３２の弾発力により常時上方に付勢されるので、外枠体２３と連結状態にある内装体４も常時上方に付勢され、内装体４は常時脚枠体１内の最上部に位置することとなる。従って、蓋体１７は常時は閉蓋状態となり、印字体１３の印面は常時は脚枠体１の下端開口より上方に位置して閉塞部１９により閉塞される。
【００２１】
又、外枠体２３を内装体４に連結させた時、脚枠体１の軸受部３、３に位置している蓋体１７の軸２１、２１は、外枠体２３の切欠部２９近傍の内側面と軸受部３、３により回動自在に挟持された状態となって軸受部３、３より離脱できなくなるので、これにより蓋体１７は分離不可能となって脚枠体１に確実に枢着された状態となる。つまり、外枠体２３を内装体４に連結させる前では、蓋体１７の軸２１、２１は脚枠体１の軸受部３、３に単に載置しただけで軸受部３、３より離脱してしまう状態にあるので、蓋体１７の枢着は完了していないものであり、外枠体２３を内装体４に連結させた時に、蓋体１７の枢着が完了する。
【００２２】
３３は弾力性を有するプラスチック製の弾性フック片で、内側面上端には内方に突出する突出部３４を設けてあり、該突出部３４より下方の外側面には外方に突出した係合部３５を設けてある。又、弾性フック片３３の下端には該弾性フック片３３と周縁で直角をなして連続する円形の固定板３６を設けてあり、この固定板３６の周縁であって弾性フック片３３の対向位置には支え片３７を設けてある。更に、固定板３６の中心には円形の貫通孔３８を設けてある。
【００２３】
この弾性フック片３３は内装体４と外枠体２３を連結する前に内装体４の筒部７の切欠部１０側に設けられるもので、固定板３６を筒部７の下端内周面に圧入嵌合することにより設けられる。そして、弾性フック片３３が切欠部１０と平行な直立状態にある時、係合部３５は切欠部１０内に位置するものとなり、前記凹部２４の底面２６と脚枠体１の上端外面が当接した時、係合部３５の上端は脚枠体１の上端内面１Ａより僅かに下方に位置するものとなる。又、支え片３７は筒部７内で固定板３６が傾くのを防いで、固定板３６をスムーズに圧入嵌合できるようにしたり、弾性フック片３３を確実に撓ませるようにするものであり、この支え片３７の外側面と筒部７の内側面を接着剤により接着することにより、弾性フック片３３を確実に分離しないように筒部７に設けることができる。尚、この支え片３７は必ずしも設ける必要はない。
【００２４】
３９はプラスチック製の偏心カムで、図７に示すように円形のカム部３９Ａと、カム部３９Ａの上面の中心から外れた位置に設けられた円柱状の連結軸４０からなるものである。又、連結軸４０の中心位置には上下方向に貫通する貫通孔４１を設けてある。尚、カム部３９Ａの外径は前記筒部７の内径より小さく、カム部３９Ａは筒部７内に収まる大きさのものである。
【００２５】
この偏心カム３９は内装体４と外枠体２３を連結する前に外枠体２３に回転自在に組み付けられるもので、外枠体２３の下端開口より連結軸４０を上向きにして挿入して該連結軸４０を外枠体２３の開口部２７を介して凹部２４内に突出させ、その突出させた連結軸４０を、凹部２４内に収まる上端が開口した断面凹状の回転体４２の底面中心に上下貫通して設けられた連結孔４３に圧入嵌合することにより、回転体４２と連結した状態で組み付けられる。従って、この偏心カム３９は回転体４２と連動して連結軸４０を軸にして回転するものである。尚、本実施の形態では図１及び図７に示すように偏心カム３９の連結軸４０の外側面に縦リブ４３を設ける一方、回転体４２の連結孔４３の内側面に縦リブ４３と係合する縦溝４４を設け、回転体４２の回転を偏心カム３９に確実に伝えるようにしてある。そして、偏心カム３９を組み付けた外枠体２３を、筒部７に弾性フック片３３を設けた状態の内装体４に連結させた時、カム部３９Ａは筒部７内に収まって該筒部７内で回転自在となり、カム部３９Ａの外周面は弾性フック片３３の突出部３４に常時当接するものとなる。又、カム部３９Ａの外周面と突出部３４との当接位置において、連結軸４０からカム部３９Ａの外周面までの寸法が最小となっている時、弾性フック片３３は直立状態となって係合部３５は切欠部１０内に位置するものとなる。
【００２６】
４５はプラスチック製の押し棒で、偏心カム３９の貫通孔４１に昇降自在に設けられるもので、上端には円形の押圧部４６を設けてある。この押し棒４５は、その下端を回転体４２の上端開口より貫通孔４１に挿入して、固定板３６の貫通孔３８と、内装体４の側壁部６、６の間と、印判取付部５の貫通孔８を貫通しているもので、更に押し棒４５の外周面に設けた環状爪４７は貫通孔４１を貫通して偏心カム３９の下方に位置するものとしてある。これにより、環状爪４７は偏心カム３９の下面と係合するので、押し棒４５は上方に抜け止め状に組み付けらたものとなっている。
【００２７】
そして、押し棒４５の環状爪４７とカム部３９Ａの下面が係合する時、押し棒４５は最上部に位置することとなり、押し棒４５が最上部に位置する時、押し棒４５の下端は貫通孔８内に位置して印判取付部５に装着された印判主体１２の摘み部１６の上面に当接するものとしてある。又、押し棒４５が最上部に位置する時、押圧部４６は回転体４２の上端開口部に位置して回転体４２の底面との間に空間が形成されるものとしており、押し棒４５はその空間分、即ち、押圧部４６が回転体４２の底面に当接するまで下降可能となっている。
【００２８】
４８は外枠体２３の上端に着脱自在かつ回転自在に嵌着されるプラスチック製の外装キャップであり、該外装キャップ４８を取外すことにより、回転体４２とこの回転体４２の上端開口部に位置する押圧部４６が露呈するものとしてある。又、外装キャップ４８の内周面対向位置には一対のリブ４９、４９を、回転体４２の外周面上端の対向位置には一対の溝５０、５０をそれぞれ設けてあり、外装キャップ４８を外枠体２３に嵌着する際にリブ４９、４９と溝５０、５０を係合させてある。よって、この外装キャップ４８を回転操作するとそれに連動して回転体４２が回転し、回転体４２に連結された偏心カム３９が回転することとなる。
【００２９】
５１はプラスチック製のロック部材である。このロック部材５１は、内面に外枠体２３のレール３０、３０に対応する一対のレール溝５２、５２を設けてあり、該レール溝５２、５２に外枠体２３のレール３０、３０を摺動自在に係止させることにより、外枠体２３に摺動自在に取付けらている。そして、ロック部材５１の下端内面には、該ロック部材５１が最下部に位置する時に蓋体１７の側板部１８と当接する当接部５３を設けてある。
【００３０】
そして、このロック部材５１が図２に示すように最下部に位置する時、当接部５３が蓋体１７の側板部１８に当接して、内装体４は下降不可能にロックされる。これは、外枠体２３を下方に押圧すると外枠体２３と連結された内装体４が脚枠体１内を下降して、これに連動して蓋体１７の案内突起２２、２２が案内孔９、９に沿って上端９Ａ、９Ａの方向に移動して脚枠体１に枢着された蓋体１７が側板部１８方向に回動しようとするが、当接部５３が側板部１８に当接していると蓋体１７は側板部１８方向への回動が阻止されるため、内装体４の下降も阻止されるからである。このように内装体４を下降不可能にロックしておけば、蓋体１７を確実に閉蓋状態に保持して印字体１３の印面を確実に閉塞状態に保持することができるので、保管時や携帯時等の未使用時において衣服や他物へのインキ汚れを防止することができる。一方、図３に示すようにロック部材５１を上方に摺動させて当接部５３と側板部１８の当接を解くことによりロックを解除して、内装体４を下降可能とすることができる。
【００３１】
尚、ロック部材５１の内面には、内装体４を下降不可能にロックしている時に突起３１と係合する係合溝５４と、そのロックを解除して内装体４を下降可能としている時に突起３１と係合する係合溝５５をそれぞれ設けてあるので、ロック部材５１はそれぞれの状態において確実に位置決めされる。よって、使用者の意に反してロック部材５１の位置が変わることはない。
【００３２】
次に、前記した本実施の形態における印判にて捺印する場合は、ロック部材５１を上方に摺動させて当接部５５と側板部１８の当接を解いた後、外枠体２３を弾発部材３２の弾発力に抗して印面方向に押圧して下降させて、内装体４を脚枠体１内で下降させることにより捺印することができる。即ち、外枠体２３を弾発部材３２の弾発力に抗して印面方向に押圧して下降させると内装体４が脚枠体１内で下降し、それに連動して蓋体１７の案内突起２２、２２は案内孔９、９に沿って上端９Ａ、９Ａの方向に移動を開始し、蓋体１７は側板部１８の方向に回動を始める。そして、外枠体２３を更に下降させて図３に示すように凹部２４の底面２６と脚枠体１の上端外面が当接すると、外枠体２３と内装体４はこれ以上下降できなくなり、最下部まで下降したこととなる。この時、案内突起２２、２２は案内孔９、９の上端９Ａ、９Ａに位置して蓋体１７は開蓋状態となり、印字体１３の印面は開放されて脚枠体１の下端開口にて露呈するので、これにより捺印することができる。
【００３３】
一方、捺印終了後は、外枠体２３への押圧を解くことにより外枠体２３が弾発部材３２の弾発力により上昇し、これにより内装体４も脚枠体１内を上昇するので、それに連動して蓋体１７の案内突起２２、２２は案内孔９、９に沿って下端９Ｂ、９Ｂの方向に移動し、蓋体１７は開蓋時とは逆方向に回動する。そして、図２に示すように側壁部６、６の上端が脚枠体１の上端内面１Ａに当接した時、内装体４は脚枠体１内の最上部に位置して上昇不可能となり、案内突起２２、２２は案内孔９、９の下端９Ｂ、９Ｂに位置して蓋体１７は閉蓋状態となって、閉塞部１９が印字体１３の印面を閉塞する。
【００３４】
又、図３に示すように蓋体１７を開蓋状態としている時に外装キャップ４８を一方向に回転操作すると蓋体１７を開蓋状態に保持することができる。即ち、蓋体１７を開蓋状態としている時に外装キャップ４８を一方向に回転操作すると、回転体４２が回転すると共にそれと連動して偏心カム３９が回転し、カム部３９Ａは弾性フック片３３の突出部３４に当接した状態で筒部７内を回転する。この時、偏心カム３９はカム部３９Ａの上面に偏心させて設けた連結軸４０を軸として回転するので、この回転により、カム部３９Ａの外周面と弾性フック片３３の突出部３４との当接箇所における連結軸４０からカム部３９Ａの外周面までの寸法は変化することとなり、その寸法が長くなるにつれて、カム部３９Ａの外周面と常時当接している突出部３４は外方に押圧され、その押圧により直立状態にあった弾性フック片３３は外方に撓む。そして、連結軸４０からカム部３９Ａの外周面までの寸法が最長となった時、図４に示すように筒部７の切欠部１０内に位置していた係合部３５は切欠部１０より外方に完全に突出して脚枠体１の上端内面１Ａの下方に位置し、この状態で蓋体１７を開蓋状態としている押圧力を解くと、外枠体２３と内装体４は弾発部材３２の弾発力により上昇しようとするが、図４に示すように係合部３５は脚枠体１の上端内面１Ａと係合するため、内装体４は上昇不可能にロックされる。これにより、蓋体１７を開蓋状態に保持することができ、印字体１３の印面を脚枠体１の下端開口にて常時露呈した状態にすることができるので、素早い連続捺印も行いやすいものとなる。
【００３５】
一方、蓋体１７を閉蓋状態とするには、内装体４を上昇不可能にロックする時とは逆方向に外装キャップ４８を回転操作して偏心カム３９を回転させて、内装体４のロックを解除すれば良く、弾性フック片３３の突出部３４が位置する箇所における連結軸４０からカム部３９Ａの外周面までの寸法が最短となった時、外方に撓んでいた弾性フック片３３は図３に示すように元の位置まで復元して係合部３５は切欠部１０内に位置し、係合部３５と脚枠体１の上端内面１Ａとの係合が解かれて、内装体４のロックは解除される。これにより、内装体４は上昇可能となり、蓋体１７を閉蓋状態とすることができる。
【００３６】
尚、本実施の形態では、図７に示すようにカム部３９Ａの上面中央に径方向に延びる段部５６を設ける一方、偏心カム３９を外枠体２３に組み付けた際にカム部３９Ａの上面と対向する凹部２４の底面２６に前記段部５６と係合する規制リブ５７を垂下して設けてある。よって、偏心カム３９の回転は、内装体４が上昇不可能にロックされる位置とそのロックが解除される位置でそれぞれ規制されるので、使用者は内装体４が上昇不可能にロックされる位置と、そのロックが解除される位置の把握がしやすいものとなっている。
【００３７】
次に、印判主体１２の着脱方法について説明する。印判主体１２の着脱は図４に示すように蓋体１７を開蓋状態として内装体４を上昇不可能にロックした状態で行うものであり、内装体４を上昇不可能にロックした後、外装キャップ４８を取外して回転体４２の上端開口部にて露呈している押し棒４５の押圧部４６を下方に押圧して、押圧部４６が回転体４２の底面に当接するまで押し棒４５を下降させる。すると、押し棒４５の下端が摘み部１６を下方に押圧して印判主体１２を下方に押し出して、図５に示すように印判主体１２の受金１５が脚枠体１の下端開口より突出した状態となる。この突出した受金１５の外周面を摘んで印判主体１２を引き出すことにより、印判主体１２を印判取付部５から取外すことができる。
【００３８】
一方、印判主体１２を取付ける場合は、蓋体１７を開蓋状態として内装体４を上昇不可能にロックした状態で印判主体１２を印判取付部５内に圧入嵌合すれば良く、摘み部１６の上面が印判取付部５の上端内面に当接することにより、印判主体１２の取付けが完了する。尚、印判主体１２を印判取付部５内に圧入嵌合する際、押し棒４５は印判主体１２により押し上げられて上昇し、印判主体１２の取付けが完了した時、押し棒４５の環状爪４７が偏心カム３９の下面に当接して、押し棒４５は最上部に位置する。
【００３９】
以上が本発明の好ましい一実施の形態である。尚、前記した一実施の形態では、筒部７に設けた弾性フック片３３は筒部７とは別体の弾力性を有するプラスチック成形品としていたが、この弾性フック片は筒部７に一体成形により設けることもできる。例えば、図８に示すように、プラスチック製の内装体４の筒部７の側面に２本のスリット７’、７’を設け、そのスリット７’、７’の間を弾力性を持つ弾性フック片３３’とし、図９に示すようにその弾性フック片３３’の上端を係合部３５’とし、その弾性フック片３３’の内側面上部に内方に突出して偏心カム３９の外周面と常時当接する突出部３４’を設けても良い。このような構成の場合、蓋体１７を開蓋状態としている時に、偏心カム３９の回転によりカム部３９Ａの外周面に当接している突出部３４’が外方に押圧されて弾性フック片３３’が外方に撓むと、該弾性フック片３３’の係合部３５’が筒部７の外側面より外方に突出して、この状態で外枠体２３と内装体４が弾発部材３２の弾発力により上昇しようとすると係合部３５’が脚枠体１の上端内面１Ａと係合するので、内装体４は上昇不可能にロックされる。
【００４０】
又、前記した一実施の形態では、外枠体２３の上端に外装キャップ４８を着脱自在かつ回転自在に設け、この外装キャップ４８を回転操作することにより回転体４２を回転させて偏心カム３９を回転させるものとしていたが、外装キャップ４８は外枠体２３に対して着脱自在とするだけで回転自在とせず、偏心カム３９を回転させる際には外装キャップ４８を取外して回転体４２を回転操作するものとしても良い。
【００４１】
【発明の効果】
以上の通り、本発明の印判では、蓋体を開蓋状態として偏心カムを回転させることにより内装体を上昇不可能にロックすることができるので、蓋体を確実に開蓋状態に保持することができる。よって、捺印時に蓋体を開蓋状態に保持しておけば、印字体の印面を脚枠体の下端開口にて常時露呈した状態としておくことができるので、素早い連続捺印も非常に行いやすいものとなる。
【００４２】
又、蓋体を開蓋状態に保持した状態で押し棒を下方に押圧して下降させることにより、内装体の下端に着脱自在に取付けられた印判主体を下方に押し出して脚枠体の下端開口より突出させることができるので、印判主体の取外し作業は蓋体を開蓋状態としたままで簡単に行うことができ、印判主体を取付ける際も、内装体を上昇不可能にロックして蓋体を開蓋状態に保持しておくことができるので、印判主体の取付け作業も簡単に行うことができる。
【００４３】
更に、本発明の印判では印判主体を従来のように専用設計としなくても、他の種類の印判に組み付けられる印判主体をそのまま流用することが可能なので、これにより部品の共通化が図れるようになる。

BACKGROUND OF THE INVENTION
The present invention is a stamp capable of continuous printing provided with a printing body made of a porous body having an infinite number of continuous pores, and more specifically, integrally provided with a lid that rotates in conjunction with a printing operation. It is related to seals.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, a stamp that can be continuously printed by impregnating ink into a printing body made of a porous material has been widely known. This type of stamp is usually fitted with a seal cap to keep the seal surface closed when not in use to prevent dirt or scratches on the seal surface or contamination of other objects by ink oozing from the seal surface. ing. And, when using it, the stamp cap was removed and stamped, and after the stamping was finished, the stamp cap was attached again, but this stamp cap was very troublesome for the user, and the stamp cap was lost. There was also a fear.
[0003]
Therefore, as a seal that solves such a problem, there is one disclosed in Japanese Utility Model Publication No. 53-44488, for example. In this stamp, the outer frame body that covers the outer periphery of the leg frame body from above is pressed downward, so that the stamp main body that is connected to the outer frame body and disposed in the leg frame body is lowered and interlocked therewith. Thus, the lid pivotally attached to the leg frame is rotated, and the printing surface of the printing body provided at the lower end of the main body of the stamp is opened, so that printing can be performed. On the other hand, after the stamping is finished, the outer frame body and the stamp main body are released by the elastic force of the elastic member disposed between the outer frame body and the leg frame body by releasing the pressure on the outer frame body. In conjunction with this, the lid rotates in the direction opposite to that when the lid is opened to close the marking surface. In this way, a stamp that is integrally provided with a lid that rotates in conjunction with a series of stamping operations cannot be separated, so the stamp surface is like a stamp that attaches or removes a separate stamp cap. There is no risk of losing the cap, and it is not necessary to attach or remove the stamp cap during use. Moreover, since there is no fear that the lid body will come off, it is convenient to carry.
[0004]
[Problems to be solved by the invention]
However, the above-mentioned stamps integrally provided with the lid body are difficult to perform quick continuous printing because the lid body rotates and opens and closes every time it is stamped. It was very inconvenient.
[0005]
Further, the conventional stamp integrally provided with the lid as described above is not configured so that the main body of the stamp can be easily attached and detached, and the main body of the stamp cannot be removed without disassembling the entire stamp. For this reason, for example, even if a problem that can be solved by replacing only the main stamper with a new one, such as aging of the printed body or the fact that the stamp surface is damaged, it becomes impossible to clear the stamp, the user Since it is difficult to remove and replace the stamp body, it is necessary to purchase the same kind of stamp again, which is inconvenient for the user.
[0006]
In addition, the stamp main body assembled to a stamp with a conventional lid is usually designed exclusively for stamps with an integral lid, so it can be assembled with other types of stamps. Can not be used for stamps with integrated lids, or used for stamps with integrated lids for other types of stamps. Could not be planned.
[0007]
Therefore, the present invention eliminates the above-mentioned problems, facilitates quick continuous stamping, and allows the user to easily attach and detach the stamp main body so that the stamp main body can be assembled to other types of stamps. An object of the present invention is to provide a stamp that is integrally provided with a lid that can be shared.

When the dimension from the connecting shaft 40 to the outer peripheral surface of the cam portion 39A is minimum at the contact position between the outer peripheral surface of the cam portion 39A and the protruding portion 34, the elastic hook piece 33 is in an upright state. The engaging part 35 is located in the notch part 10.
[0026]
Reference numeral 45 denotes a plastic push rod which is provided in the through hole 41 of the eccentric cam 39 so as to be movable up and down. A circular pressing portion 46 is provided at the upper end. The lower end of the push rod 45 is inserted into the through hole 41 from the upper end opening of the rotating body 42, and between the through hole 38 of the fixing plate 36, the side wall portions 6 and 6 of the interior body 4, and the stamp attachment portion 5. Further, an annular claw 47 provided on the outer peripheral surface of the push rod 45 passes through the through hole 41 and is positioned below the eccentric cam 39. As a result, the annular pawl 47 engages with the lower surface of the eccentric cam 39, so that the push bar 45 is assembled upward in a retaining shape.
[0027]
When the annular claw 47 of the push bar 45 and the lower surface of the cam portion 39A are engaged, the push bar 45 is positioned at the uppermost position. When the push bar 45 is positioned at the uppermost position, the lower end of the push bar 45 is It is assumed that it is in contact with the upper surface of the knob portion 16 of the stamp main body 12 that is located in the through hole 8 and is attached to the stamp mounting portion 5. In addition, when the push bar 45 is located at the uppermost part, the pressing part 46 is located at the upper end opening of the rotating body 42 and a space is formed between the bottom surface of the rotating body 42. The space can be lowered until the pressing portion 46 comes into contact with the bottom surface of the rotating body 42.
[0028]
A plastic outer cap 48 is detachably and rotatably fitted to the upper end of the outer frame body 23. By removing the outer cap 48, the rotary body 42 and the upper end opening of the rotary body 42 are positioned. The pressing part 46 to be exposed is assumed to be exposed.

Therefore, when this exterior cap 48 is operated to rotate, the rotating body 42 rotates in conjunction with it, and the eccentric cam 39 connected to the rotating body 42 rotates.
[0029]
Reference numeral 51 denotes a plastic locking member. The lock member 51 is provided with a pair of rail grooves 52 and 52 corresponding to the rails 30 and 30 of the outer frame body 23 on the inner surface, and the rails 30 and 30 of the outer frame body 23 are slid into the rail grooves 52 and 52. By being movably locked, the outer frame body 23 is slidably attached. A contact portion 53 that contacts the side plate portion 18 of the lid 17 when the lock member 51 is located at the lowermost portion is provided on the inner surface of the lower end of the lock member 51.
[0030]
When the lock member 51 is positioned at the lowermost position as shown in FIG. 2, the contact portion 53 contacts the side plate portion 18 of the lid body 17, and the interior body 4 is locked so as not to be lowered. This is because when the outer frame body 23 is pressed downward, the interior body 4 connected to the outer frame body 23 is lowered in the leg frame body 1, and the guide protrusions 22, 22 of the lid body 17 are guided in conjunction with this. The lid 17 that is pivotally attached to the leg frame 1 by moving in the direction of the upper ends 9A and 9A along the holes 9 and 9 tries to rotate in the direction of the side plate 18, but the abutment 53 is the side plate 18. This is because the lid body 17 is prevented from rotating in the direction of the side plate portion 18 and thus the lowering of the interior body 4 is also prevented. If the interior body 4 is locked in such a manner that it cannot be lowered, the lid body 17 can be reliably held in the closed state and the printing surface of the printing body 13 can be reliably held in the closed state. Ink stains on clothes and other items can be prevented when not in use, such as when being carried or carried. On the other hand, as shown in FIG. 3, the lock member 51 is slid upward to release the contact between the contact portion 53 and the side plate portion 18, thereby releasing the lock and allowing the interior body 4 to be lowered. .
[0031]
The inner surface of the lock member 51 has an engagement groove 54 that engages with the protrusion 31 when the interior body 4 is locked so as not to be lowered, and when the interior body 4 can be lowered by releasing the lock. Since the engagement grooves 55 that engage with the protrusions 31 are provided, the lock member 51 is reliably positioned in each state. Therefore, the position of the lock member 51 does not change against the user's will.
[0032]
Next, in the case of printing with the stamp in the above-described embodiment, after the lock member 51 is slid upward to release the contact between the contact portion 55 and the side plate portion 18, the outer frame body 23 is elastically moved. Printing can be performed by pressing and lowering the inner body 4 in the leg frame 1 by pressing and lowering in the direction of the marking surface against the elastic force of the emitting member 32. That is, when the outer frame body 23 is pressed and lowered in the direction of the marking surface against the elastic force of the elastic member 32, the interior body 4 descends in the leg frame body 1, and the lid 17 is guided in conjunction therewith. The protrusions 22 and 22 start to move along the guide holes 9 and 9 toward the upper ends 9 A and 9 A, and the lid 17 starts rotating in the direction of the side plate portion 18. Then, when the outer frame body 23 is further lowered and the bottom surface 26 of the recess 24 and the upper end outer surface of the leg frame body 1 come into contact with each other as shown in FIG. 3, the outer frame body 23 and the interior body 4 can no longer be lowered. It will descend to the bottom. At this time, the guide protrusions 22 and 22 are positioned at the upper ends 9A and 9A of the guide holes 9 and 9 so that the lid body 17 is in an open state, the printing surface of the printing body 13 is opened, and the lower end opening of the leg frame body 1 is opened.
