Description

【０００１】
【発明の属する技術分野】
本発明は、不正規な再利用を防止したレンズ付きフイルムユニットに関するものである。
【０００２】
【従来の技術】
予め写真フイルムが装填され、簡単な撮影機構を備えたレンズ付きフイルムユニットが各種販売されている。使用済みのレンズ付きフイルムユニットは製造メーカーによって回収され、構成部品ごとにリユース、あるいはリサイクルされている。
【０００３】
リサイクルすることを前提として製造されているレンズ付きフイルムユニットは、ユーザやメーカ以外の業者によるフイルムの詰め替えを防止するために、ファインダや撮影機構が組み込まれた本体基部と、この本体基部の背面を覆う後カバーとを強固に数ヶ所溶着結合している。このため、本体基部から後カバーを無理に取り外したときには、本体基部と後カバーとが破損し、遮光性能が損なわれるようにしている。
【０００４】
ところで、本体基部と後カバーとをインパルス溶着により溶着結合するには、例えば、本体基部に後カバーに向けて突出させた突出片を設けるとともに、後カバーにこの突出片が貫通する開口を設け、開口から突出した突出片を溶融することにより行う。（例えば、特許文献１参照）
【０００５】
【特許文献１】特願２００１−１４８７３４号明細書
【０００６】
【発明が解決しようとする課題】
しかしながら、上記のようなレンズ付きフイルムユニットでは、本体基部と後カバーとを溶着結合する溶着結合部がユニット表面に露呈しているため、この溶着結合部をカッターなどで削り剥がすことにより、容易に本体基部から後カバーを取り外せてしまうという欠点があった。
【０００７】
本発明は、上記背景を考慮したもので、本体基部と後カバーとの溶着結合部をユニット内部に設けて、フイルムの詰め替えを防止することができるレンズ付きフイルムユニット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】
上記目的を達成するために、本発明のレンズ付きフイルムユニットは、露光開口の両端にカートリッジ室及びフイルムロール室が形成された本体基部と、この本体基部の後面に取り付けられる後カバーとを有し、前記露光開口と後カバーとの間に写真フイルムを給送するためのフイルム通路が形成されたものであり、一方の端部にカギ型の係止爪が形成され、この係止爪を前記後カバーに形成された開口から挿入して、前記本体基部と係合させることにより、前記後カバーを前記本体基部との間で挟み込んで固定する取付部材を備え、この取付部材は、透明な樹脂で形成されており、前記係止爪は、前記本体基部との係合により前記本体基部内面と当接し、外部から照射され、且つ透明な樹脂内部を透過するレーザ光によって前記本体基部とレーザ溶着される溶着面と、この溶着面に前記レーザ光を反射するための反射面とが設けられることを特徴とする。
【０００９】
前記取付部材には、前記後カバーに当接して前記係合爪の挿入量を規制するストッパと、前記後カバーに形成された開口とは異なる開口から挿入して本体基部の凹部に進入することにより前記取付部材を所定位置に位置決めする位置決め片とが一体に設けられており、更に、前記ストッパと前記後カバーとが接触する接触面と、前記位置決め片と前記本体基部とが接触する接触面とが、それぞれ前記レーザ光によって溶着されることを特徴とする。また、前記開口は前記フイルム通路の上下付近に形成しておくのが、目的を達成するうえでより効果的である。
【００１０】
【発明の実施の形態】
図１は、本発明のレンズ付きフイルムユニットを分解して示す斜視図である。このレンズ付きフイルムユニットは、ユニット本体１０と、このユニット本体１０の外周を帯状に被覆するラベル４９（図４参照）から構成される。このユニット本体１０は、前カバー１１、後カバー１２、本体基部１３及び取付部材１４，１５から構成される。
【００１１】
本体基部１３の両端側には、図示しないフイルムカートリッジを収納するためのカートリッジ室２０と、未露光の写真フイルムがロール状に巻かれたフイルムロールが収納されるフイルムロール室２１とが形成されている。これらフイルムカートリッジ室２０及びフイルムロール室２１の間には、露光開口２３が形成されている。この露光開口２３の上下には、露光済みの写真フイルムを所定方向に給送し、且つ写真フイルムの巻き取り時の巻き取りズレを防止するためのガイドレール２５，２６が形成されている。なお、本体基部１３には、図示しない撮影機構や、フイルム巻取り機構等が組み込まれるが、周知であるため詳細は省略する。
【００１２】
後カバー１２は、本体基部１３との間に形成されるフイルム通路２６（図２参照）内部を光密に保持するために設けられている。この後カバー１２には取付部材１４，１５を組み付けるための取付部３０，３１が形成されている。図２に示すように、取付部３０は、後カバー１２の後面側に形成された凹部３０ａにスリット状の第１開口３０ｂ及び第２開口３０ｃが形成された構成となっている。なお、後カバー１２を本体基部１３に組み付けると、第２開口３０ｃがガイドレール２５に形成されたレール溝２５ａの前面に位置し、ガイドレール２５の当接面２５ｂ及び２５ｃが、後カバー１２の当接面１２ａ及び１２ｂと当接するようになっている。なお、取付部３０についてのみ説明したが、取付部３１は同一の構成となるため説明は省略する。
【００１３】
取付部材１４，１５は上述したように、後カバー１２を本体基部１３の所定位置に組み付け固定するために設けられている。この取付部材１４，１５は、例えば透明なプラスチック部材により形成されている。なお、取付部材１４，１５の構成は同一であるため、以下では取付部材１４の説明を行う。この取付部材１４は、ストッパ３２、位置決め片３３及び係止爪３４が一体に形成された構成となっている。ストッパ３２は、係止爪３４がユニット本体１０の内部に挿入される挿入量を規制するために設けられている。ストッパ３２が後カバー１２の取付部３０の凹部３０ａに挿入されるとともに、ストッパ３２の当接面３２ａ〜３２ｃは後カバー１２の当接面１２ｃ〜１２ｅに当接する。また、位置決め片３３は、取付部材１４を後カバー１２及び本体基部１３の所定位置に位置決めするために設けられている。位置決め片３３が後カバー１２の第２開口３０ｃ及びガイドレール２５のレール溝２５ａに挿入されるとともに、この位置決め片３３の先端面（当接面）３３ａはガイドレールのレール溝２５ａの底面（当接面）２５ｄに当接する。このように、取付部材１４のストッパ３２及び位置決め片３３と当接する、後カバー１２及び本体基部１３の当接面は、外部から照射され取付部材１４内部を透過するレーザ光により溶着される溶着面でもある。

係止爪３４は、本体基部１３の所定位置に形成された係合部１３ａと係合させるために設けられている。この係止爪３４には、取付部材１４の内部を透過するレーザ光を反射させるための反射面３４ａ， ３４ｂが形成される。係止爪３４が本体基部１３の係合部１３ａに係合されるとともに、係止爪３４の当接面３４ｃは係合部１３ａの当接面２５ｅに当接する。この当接面２５ｅは、外部から照射され取付部材１４内部を透過するレーザ光により本体基部１３と溶着される溶着面でもある。
【００１５】
次に、上記構成による作用について説明する。撮影機構やフイルム巻取機構が組み付けられた本体基部１３に前カバー１１が組み付けられた後に、カートリッジ室２０及びフイルムロール室２１にカートリッジ本体から引き出されてロール状に巻かれた写真フイルム４０が装填される。この後、後カバー１２を本体基部１３に組み付けるとともに、ガイドレール２５の当接面２５ｂ及び２５ｃが後カバー１２の当接面１２ａ及び１２ｂに当接される。
【００１６】
後カバー１２が本体基部１３に組み付けられた後に、取付部材１４を後カバー１２の凹部３０ａから組み付ける。このとき、取付部材１４の係止爪３４が本体基部１３の係合部１３ａと係合して、係止爪３４の当接面３４ｃは係合部１３ａの当接面２５ｅに当接する。また、位置決め片３３が後カバー１２の第２開口３１ｃ及びガイドレール２５のレール溝２５ａに挿入され、位置決め片３３の先端面（当接面）３３ａはこのレール溝２５ａの底面（当接面）２５ｄに当接する。更に、ストッパ３２が後カバー１２の凹部３０ａに挿入され、ストッパ３２の当接面３２ａ〜３２ｃは後カバー１２の当接面１２ｃ〜１２ｅに当接する。次に、図３に示すように、ユニット本体１０の背面からレーザ光を照射する。このとき、このレーザ光は取付部材１４内部を透過して、且つ反射面３４ａ， ３４ｂで反射して係合部１３ａの当接面２５ｅに達するとともに、この当接面２５ｅを溶融する。この当接面２５ｅの溶融により係止爪３４の当接面３４ｃと、係合部１３ａの当接面２５ｅとが溶着する。同様に、取付部材１４内部を透過したレーザ光がレール溝２５ａの底面（当接面）２５ｄを溶融して、位置決め片３３の先端面（当接面）３３ａと、レール溝２５ａの底面（当接面）２５ｄとが溶着する。また、後カバー１２の当接面１２ｃ〜１２ｅを溶融して、ストッパ３２の当接面３２ａ〜３２ｃと、後カバー１２の当接面１２ｃ〜１２ｅとが溶着する。
【００１７】
上記のようにして、取付部材１４を用いて、本体基部１３と後カバー１２とを組み付けて固定し、この取付部材１４と本体基部１３及び後カバーとの溶着結合部をレーザ溶着によりユニット本体１０内部に設けるようにしたから、本体基部１３から後カバー１２を取り外すことが困難になる。また、この溶着結合部はフイルム通路２６上方に配置されているが、位置決め片３３が後カバー１２の第２開口３０ｃ及びガイドレール２５のレール溝２５ａに挿入され、後カバー１２が本体基部１３の所定位置で固定されることで、外光がフイルム通路２６内に侵入して装填した写真フイルム４０が感光してしまうことはない。これにより、本体基部１３から後カバー１２を無理に取り剥がした場合には、取付部材１４は不定形に割れてしまうので、フイルム通路２６内の遮光が困難になり、不正規な再使用を防止することができる。
【００１８】
溶着が終了したユニット本体１０には、図４に示すように、取付部材１４，１５などをカバーするようにしてラベル４９が貼り付けられ、レンズ付きフイルムユニット５０が完成する。ラベル４９を貼り付けることにより、取付部材１４， １５が外部に露呈されないので、レンズ付きフイルムユニット５０の外観デザインを損なうことがない。
【００１９】
上記実施形態では、取付部材１４， １５は、ストッパ３２、位置決め片３３及び係止爪３４から構成されるが、これら形状は適宜形状にしてもよい。また、これら形状に応じて、後カバー１２及び本体基部１３の形状も適宜とする。
【００２０】
上記実施形態では、当接面は平らであるが、楔面にして強力にレーザ溶着させてもよい。
【００２１】
上記実施形態では、反射面３４ａ， ３４ｂに照射されたレーザ光の一部は、これらの反射面３４ａ， ３４ｂをすり抜けてしまうが、レーザ光をより多く反射させるために反射面３４ａ， ３４ｂに例えば蒸着を施してレーザ光の反射効率を上げるようにしてもよい。
