【発明の属する技術分野】
本発明は、感光材料を処理する感光材料処理装置の複数の処理液槽に、収納容器内に収容された異なる種類の固形処理剤を各対応する処理液槽に所定量投下して補給する感光材料処理用固形処理剤補給装置に関する。
【0002】
【従来の技術】
ハロゲン化銀写真感光材料(以下感光材料とも称す)は、露光後に、現像液、漂白液、定着液、安定化液等の処理液による処理工程により処理される。この処理は通常自動現像機で行われ、その場合は補充液補充方式が一般に用いられ、処理槽内の各処理液の活性度を一定に保つようにコントロールされている。
【0003】
補充液補充方式の場合、感光材料からの溶出物による処理液の希釈、蒸発量の補充および消費成分の補充を目的としており、液体補充の結果、通常オーバーフロー液が多量に排出されている。
【0004】
感光材料の処理を商業的に実施するには、コストおよび人手作業の軽減、公害負荷の低減、処理装置のコンパクト化、更には商品価値の向上のため、できるだけ少量の処理液で、安定かつ優れた処理性能を得ることが要求される。
【0005】
この要望に応える方法として、WO92/20013号公報には、殆ど全ての処理剤成分を固形処理剤化し、直接処理槽に投入する方法が開示されている。
【0006】
しかし、この方法では、感光材料の処理量を検知して、複数の各処理槽内の処理液に、所定量の異なる固形処理剤を個々に制御して補充しているため、各固形処理剤の投入量、投入タイミングを制御する制御装置が複雑になり、故障する確率が上がり、さらに装置の大きさも大きくなってしまうという問題がある。また複数の収納容器内に収容された異なる各固形処理剤の消費量が著しく異なるため、収納容器内の固形処理剤残量に差異があり、各収納容器を個別に消費済み毎に交換する保守操作が煩わしくなる。従ってこれらの問題を解決する固形処理剤補給装置の技術開発が急務である。
【0007】
【発明が解決しようとする課題】
この発明は、下記の問題点を解消することを目的とするものである。
【0008】
・従来は収納容器を装填するときに上ユニットが回動するために、耐久性がない。
【0009】
・収納容器の装填時に、収納容器開口部と装着部との密着性が損なわれないようにする必要がある。
【0010】
・ネガフィルム用とペーパー用の収納容器の誤装填、あるいは装填方向の誤挿入を簡単な構造で防止する必要がある。
【0011】
・処理液槽側からのガスが収納容器内に侵入すると、固形処理剤が膨潤する等の問題がある。
【0012】
・収納容器の装填時に、収納容器開口部から外気が侵入して、収納容器内の固形処理剤が膨潤する。
【0013】
【課題を解決するための手段】
上記目的を達成する本発明の感光材料処理用固形処理剤補給装置は、複数の固形処理剤を投入するユニット化した処理剤投入部を備え、この処理剤投入部に複数の固形処理剤を収納した収納容器を装填可能に構成し、前記処理剤投入部から固形処理剤を処理液槽に投入して溶解し処理液の補充を行う感光材料処理用固形処理剤補給装置であり、前記補給装置は、前記処理剤投入部のハウジングに固定され前記収納容器の処理剤投入側を保持する投入側装填ユニットと、前記ハウジングに固定され収納容器の処理剤非投入側を保持して前記処理剤投入側へ付勢する押圧側装填ユニットとを有し、かつ前記押圧側装填ユニットに、ガイド溝部と、このガイド溝部に連続して回転可能に保持する保持凹部とを設け、所定の収納容器の処理剤非投入側の両側部に突出して設けられた支持ピンのみが前記ガイド溝部から保持凹部に装填可能に構成したことを特徴とするものである(請求項1)。
【0014】
また、本発明の感光材料処理用固形処理剤補給装置は、前記押圧側装填ユニットに、前記収納容器の処理剤投入側を投入側へ付勢するセット方向付勢手段を備えたことを特徴とするものである(請求項2)。
【0017】
さらに、本発明の感光材料処理用固形処理剤補給装置は、前記投入側装填ユニットに、前記収納容器のそれぞれの投入開口部に対向して固形処理剤を投入するガイド口を有する投入ガイド開口部を設け、この投入ガイド開口部のガイド口の周辺を覆う収納容器パッキンを設けたことを特徴とするものである(請求項)。
【0019】
【発明の実施の形態】
次に、本発明の一実施形態を添付図面に基づいて説明するが、本発明は、これに限定されるものではない。
【0020】
本発明の自動現像機(以下、単に自現機ともいう)の一例を図面に基づいて説明する。図1(a)は、自現機APと写真焼付機Bとを一体的に構成したハロゲン化銀写真感光材料処理装置(プリンタープロセッサ)の正面側全体構成図である。
【0021】
図1(a)において、写真焼付機Bの左下部には、未露光のハロゲン化銀写真感光材料である印画紙(カラーペーパー)をロール状に収納したマガジンMaがセットされる。マガジンMa内の印画紙は、送りローラR1により所定長さが引き出され、カッター部Ctにより所定のサイズに切断され、シート状印画紙pとなる。このシート状印画紙pは、送りローラR2によって搬送され、回動する搬送ベルトBe及び搬送ベルトBeの下方に設けられているバキューム手段Vに吸引されながら露光位置まで移動し、停止、待機する。
【0022】
ネガキャリアNe上にセットされたネガフィルムに対して光源部La、レンズLe、シャッタStにより、原画の画像を露光される。露光が終了すると、シート状印画紙pは搬送ベルトBeにより再び搬送され、さらに送りローラR3,R4及び複数対の送りローラR5により搬送され、自現機AP内に導入される。
【0023】
自現機APでは、シート状印画紙pは、処理液槽であるそれぞれ発色現像槽1A、漂白定着槽1B、安定槽1C,1D,1E内(実質的に3槽構成の処理槽1)をローラ搬送手段(参照記号ナシ)により順次搬送され、それぞれ、発色現像処理、漂白定着処理、安定化処理がなされる。前記各処理がなされたシート状印画紙pは、乾燥部6において乾燥されて機外に排出される。
【0024】
また、シート状印画紙pはカットされた状態で自現機AP内に導かれるものであるが、帯状で自現機AP内に導かれるものであってもよい。
【0025】
また、本願発明に係る自現機APは、写真焼付機Bと一体的に構成しても、自現機AP単体だけでもよいことは言うまでもない。また、本発明の説明として、発色現像槽1A、漂白定着槽1B、安定槽1C,1D,1Eを有する実質的に3槽構成の処理槽1を有する自現機APについて行うが、これに限られるものではなく、露光済みのネガフィルムを処理する発色現像槽、漂白槽、定着槽、安定槽を有する実質的に4槽または、それ以上の処理槽を有する構成の自現機であっても本発明は適用できるものである。
【0026】
図1(b)は自現機APの平面構成図である。上記発色現像槽1A、漂白定着槽1B、安定槽1Eの各処理槽には、補助タンク2A,2B,2C,2D,2Eが連設されている。該補助タンク2A,2B,2Eには、固形処理剤補給装置(以下、補給装置と称す)30から固形処理剤が供給される。40は、前記補給装置30に着脱可能に装着する固形処理剤収納容器(カートリッジ、以下、収納容器と称す)である。
【0027】
51は、前記発色現像槽1A、安定槽1Eに補充水を供給する補充水タンクである。
【0028】
図2(a)はシート状印画紙現像処理用の自現機APの構成図である。自現機APでは、シート状印画紙pは、発色現像槽1A、漂白定着槽1B、安定槽1C,1D,1E内の各処理液(CD,BF,SR1〜3)により処理されたのち乾燥部6で乾燥される。液面レベルとして漂白定着槽1Bに対し、安定槽1C,1D,1Eが順次高くなっている。従って1Eからのオーバーフロー液は重力により1D,1C,1Bと流れこむような構造(カウンターカレント方式)となっている。51は補充水タンク、52は給水ポンプ、53は送水管、54は補充水供給制御手段である。56は印画紙の処理量を検知する処理量情報検出手段、57は前記処理量情報に基づき所定量の固形処理剤を適時補給する固形処理剤供給制御手段である。30Pは自現機APに固形処理剤を補給する補給装置である。
【0029】
図2(b)はネガフィルム現像処理用の自現機ANの構成図である。該自現機ANでは、ネガフィルムfは、処理液槽である発色現像槽1NA、漂白槽1NB、定着槽1NC,1ND、安定槽1NE,1NF,1NG内の各処理液(CD,BF,SR1〜3)により処理されたのち乾燥部6で乾燥される。上記発色現像槽1NA、漂白槽1NB、定着槽1ND、安定槽1NGの各処理液槽には、それぞれ固形処理剤を供給する補給装置30が設けてある。30Nは自現機ANに固形処理剤を補給する補給装置である。なお、前記自現機APと同じ機能を有する部分には、図2(a)と同一符号を付してある。
【0030】
図3は、図1の自現機APのZ−Z断面における処理槽である発色現像槽1Aと補助タンク(溶解槽)2Aと補給装置30の断面図である。漂白定着槽1Bおよび安定槽1Eもほぼ同一構造をなすから、以下発色現像槽1Aを代表して説明する。
【0031】
なお、図には、構成をわかりやすくするために、感光材料を搬送する搬送手段等は省略してある。また、本例においては、固形処理剤として錠剤型固形処理剤Jを用いた場合について説明するが、顆粒状固形処理剤にも適用可能である。
【0032】
感光材料(p又はf)を処理する処理槽1Aは、該処理槽1Aを形成する仕切壁21の外側に一体的に設けた補助タンク(溶解槽)2Aを有する。処理槽1Aと補助タンク2Aとは連通窓21Aが形成された仕切壁21により仕切られており、処理液は流通できるようになっている。補助タンク2A内にはフィルタ22、ヒータ25、温度センサ26、液面センサ27が設けてある。このフィルタ22の中は、補助タンク2Aの下方壁を貫通して設けられた循環パイプ23Aを介して循環ポンプ24(循環手段)の吸引側に連通している。前記循環ポンプ24の吐出側に連通した循環パイプ23Bの他端は処理槽1の外壁を貫通し、該処理槽1に連通している。この様な構成により、循環ポンプ24が作動すると処理液は補助タンク2Aから吸い込まれ、処理槽1Aに吐出されて、処理液は処理槽1A内の処理液と混じり合い、再び補助タンク2Aへと入り循環を繰り返すことになる。11はオーバーフロー管、12は廃液タンクである。
【0033】
前記補助タンク2Aに補充水Wを供給する補充水供給手段50は、補充水タンク51、給水ポンプ52、送水管53A,53Bから構成されていて、補充水供給制御手段54により適時適量の補充水Wを補給する。
【0034】
補給装置30は、処理量情報検出手段56、固形処理剤供給制御手段57(以上図3参照)、錠剤型固形処理剤Jを収容する収納容器40、補給装置30から構成されている。該補給装置30はモータMにより駆動される。自現機APの上部カバー102の上面の一部には、蓋104が揺動自在に蝶合されていて、該蓋104を図示一点鎖線a方向に開放して、前記収納容器40を装填または交換して錠剤型固形処理剤Jの補充を行う。
【0035】
図4は収納容器40を構成する各部品の斜視図であり、図5は一部破断面を含む収納容器40の斜視図であり、図6は(a)は一部破断面を含む収納容器40の平面図、図6(b)は側面図、図6(c)はA−A断面拡大図である。

図7(a)はネガカラーフィルム現像処理用の自現機ANの各処理槽に補給する固形処理剤(JN1〜JN4)を収容する収納容器40Nの正面断面図、図7(b)はカラー印画紙現像処理用の自現機APの処理槽に補給する固形処理剤(JP1〜JP3)を収容する収納容器40Pの正面断面図である。
【0037】
図8(a)は蓋部材(処理剤投入側部材)42の斜視図、図8(b)〜(d)は蓋部材42の開閉操作を示す部分断面図である。
【0038】
収納容器40Nは、カラーネガフィルムの処理、すなわち、発色現像、漂白、定着、安定化の各処理毎に錠剤に固形化した固形処理剤JN1、JN2、JN3、JN4を収納する収納容器である。収納容器40Pは、カラー印画紙の処理、すなわち、発色現像、漂白定着、安定化の各処理毎に錠剤に固形化した固形処理剤JP1、JP2、JP3を収納する収納容器である。
【0039】
なお、収納容器40Nは、カラーネガフィルム100本分を処理することができる量の固形処理剤JN1〜JN4を収納するものである(発色現像用の固形処理剤JN1は10錠、漂白用の固形処理剤JN2は10錠、定着用の固形処理剤JN3は40錠、安定化用の固形処理剤JN4は1錠を収納する)。また、収納容器40Pは、発色現像用の固形処理剤JP1を20錠、漂白定着用の固形処理剤JP2を40錠、安定化用の固形処理剤JP3を5錠収納する。
【0040】
収納容器40は、先端側(蓋部材42が設けられる側であり、図6(a)において左側)及び後端側(キャップ部材43が設けられる側であり、図6(a)において右側)が開放された中空であって筒状の容器本体41と、容器本体41の先端側を覆うことができ開閉可能な蓋部材4と、容器本体41の後端側を覆うキャップ部材(処理剤非投入側部材)43とを有している。これら容器本体41、蓋部材42、及びキャップ部材43は、例えば、PE(ポリエチレン)、PP(ポリプロピレン)、ABS(アクリルブタジエンスチレン)などによって樹脂成形されるが、本実施の形態では、固形処理剤J1〜J4の成分を鑑み、PE或いはPPが好ましく用いられ、さらに、収納容器は薄肉深物であるため、PE、PP材料は高流動性のものが好ましい。
【0041】
容器本体41の内側には、仕切部材として仕切壁411A、411B、411C、411Dが一体的に設けられており、これらの仕切壁411(A〜D)及び容器本体41の外壁によって、容器本体41内を、実質的に5つの収納室412A、412B、412C、412D、412Eを構成している。すなわち、これら仕切壁411(A〜D)は、容器本体41内の上面(図6(b)において上側の面)から底面(図6(b)において下側の面)まで連なった平板状を呈しており、換言すると、上面及び底面と仕切壁411(A〜D)とが結合されており、各収納室412(A〜E)を互いに連通しないように構成されている。さらに、この仕切壁411(A〜D)は、後述する投入開口部414A、414B、414C、414Dより突出するように構成されている。なお、仕切壁411Bの肉厚は、他の仕切壁411A、411C、411Dの肉厚よりも厚くなっている。また、収納室412(A〜E)の後端側は開放されているが、キャップ部材43によってその開放されている部分が覆われている。また、収納室412Eの後端側は開放しないように、容器本体41の樹脂成形時に形成されている。
【0042】
各収納室412(A〜E)は、固形処理剤Jを縦列状態に収納することができる。これら5つの収納室412(A〜E)のうち4つの収納室412A、412C、412D、412Eに固形処理剤JN1、JN2、JN3、JN4を収納し、収納室412Bは固形処理剤Jを収納しない収納室(以下、空室ということもある)となっている。これは、現像用の固形処理剤JN1に、定着用の固形処理剤JN2の成分が混ざると、現像性能に多大な悪影響を与えるため、空室を設けることにより、収納室412Aと収納室412Cとの間の距離を設け、固形処理剤JN2の収納或いは排出時に発生する固形処理剤JN2の成分を含んだ粉が入り込む(所謂、コンタミ)を防止するためである。
【0043】
カラー印画紙現像処理用の自現機APの処理槽に補給する固形処理剤(JP1〜JP3)を収容する収納容器40Pは、前記収納容器40Nと同一形状である。収納容器40Pには、図7(b)に示すように、発色現像用の固形処理剤JP1を収納する収納室412Aと、漂白定着用の固形処理剤JP2を収納する収納室412Cととの間に、空室412Bを設けた。
【0044】
なお、本実施の形態では、収納室412(A〜E)は、容器本体41の先端側から後端側までの長さが、固形処理剤Jを10錠分収納できるだけの長さを有している。この場合、収納室412(A〜E)は、定着用の固形処理剤JN3を40錠も収納するため、その内部をさらに4つの分室に区切るように、3つの区切壁413が設けられている。この区切壁413は、固形処理剤JN3と接触することが可能な長さだけ容器本体41内の上面及び底面から突出するように設けられ(上面から底面まで連なってはいない)、固形処理剤JN3を縦列で収納可能な程度の区切りでよいが、仕切壁411(A〜D)と同様に上面から底面まで連なった平板状であってもよい。また、この区切壁413は、投入開口部414(A〜E)から突出しないように設けているが、突出するように設けてもよい。また、収納室125は、固形処理剤JNを1錠分収納する長さを有していればよいが、固形処理剤JNを3錠分収納できるだけの長さを有している。これは、後段において説明するが、本実施の形態の収納容器は、カラーネガフィルムを処理するための固形処理剤JNを収納するものであるが、カラーペーパーを処理するための固形処理剤JPを収納する収納容器40Pと兼用するために、固形処理剤JNを5錠分収納するだけの長さを有している。
【0045】
また、各収納室412(A〜E)内には、各収納室412(A〜E)の内面との接触面積を減らし、固形処理剤JNの収納或いは排出を容易に行い、かつ、収納している固形処理剤JNが各収納室412(A〜E)の内面に密着を防ぐために、容器本体41内の上面、底面、各仕切壁411(A〜D)、及び、区切壁413それぞれに、容器本体41の先端側から後端側へと伸びるリブ(符号なし)が設けられている。
【0046】
これら各収納室412(A〜E)は、容器本体41の先端側に投入開口部414(A〜E)が設けられており、この投入開口部414(A〜E)から固形処理剤JNを収納或いは排出することができる。また、これら投入開口部414(A〜E)の周囲には(容器本体41の先端側)、投入開口部414(A〜E)を囲むように平面状のフランジ部415が設けられている。このフランジ部415の両側端部415A,415Bは、後述する蓋部材42の係合部421A,421Bと係合するよう構成されている。さらに、このフランジ部415の上端部には後述する蓋部材42の第1係止部426を係止する被係止部としての係止切欠416が設けられている。また、収納室412(A〜E)の後端側の開放に対しては、後述するキャップ部材43が嵌合するように構成されている。
【0047】
蓋部材42は、投入開口部414(A〜E)に対してスライドすることにより、投入開口部414(A〜E)を覆い、かつ、開閉することが可能な部材である。蓋部材42をスライドさせるために、容器本体41のフランジ部415の両側端部415A,415Bと係合するコの字状の係合部421が、蓋部材42の両側端側(スライドする方向と直交する方向における両端側)に設けられている。このコの字状の係合部421は、上端側(閉める方向に対して上流端側)より下端側(閉める方向に対して下流端側)の方が、コの字状の間隙が広がるように構成されている。さらに、係合部421には、蓋部材42をフランジ部415の両側端部415A,415Bに係合させる際の作業を容易に行わせるため、蓋部材42のスライド方向の一端側(本実施の形態では、下端側)において切り欠き428が設けられている(図8(a)参照)。また、この蓋部材42が投入開口部414(A〜E)と対向する面には、仕切壁411(A〜D)の投入開口部414(A〜E)から突出した部分と嵌合する嵌合部である溝部422(A〜D)が設けられている。さらに、蓋部材42が投入開口部414(A〜E)と対向する面には、蓋部材42が下がり過ぎずに投入開口部414(A〜E)を覆う位置で停止させるために、蓋部材42の上端に、フランジ部415の係止切欠416によって係止される第1係止部426と、蓋部材42が容易に上がらない(開かない)ようにフランジ部415の下端面(符号なし)によって係止される第2係止部427とが設けられている。なお、蓋部材42の両側面に設けられた操作部材429は、蓋部材42を上方へスライドさせる際に、第2係止部427によるフランジ部415の下端面への係止状態を解除するため、さらに、蓋部材42をスライドさせるための操作が行われるために設けられている。
【0048】
キャップ部材43は、開閉されている容器本体41の後端側を覆う、すなわち、収納室412(A〜E)の後端側を覆う部材である。収納室412(A〜E)に収納される固形処理剤JNから生じる粉塵などが他の固形処理剤を収納する収納室に侵入しない(所謂コンタミ防止)ために、容器本体41の後端に対向するキャップ部材43の内壁には、仕切壁411(A〜D)と嵌合する嵌合溝431〜433が設けられている。さらに、このキャップ部材43の内壁の周囲には、収納室412(A〜E)内の固形処理剤JNから生じる粉塵などが収納容器40から出ないように、容器本体41の外壁(この場合は容器本体41の後端側であるので、収納室412(A〜E)の周囲である)と嵌合する嵌合溝434が設けられている。なお、図1に示すように、各収納室412(A〜E)それぞれに相当するキャップ部材43の内面に突起(符号なし)が設けることにより、キャップ部材43の内面と固形処理剤JNとが密着することを防止している。
【0049】
次に、この収納容器40の組み立て及び固形処理剤JNの収納について説明する。先ず、キャップ部材43の内面の嵌合溝431(A〜C)が、それぞれ容器本体41の仕切壁411(A〜D)と容器本体41の外壁とを嵌合させるようにして、容器本体41の後端側にキャップ部材43を取り付け、開放されていた容器本体41の後端側を覆う。このとき、キャップ部材43と容器本体41とに跨ってシール部材35を捲着させることにより、容器本体41の後端側から固形処理剤JNの粉塵が外部に漏れ出すことを完全に防止している。次いで、発色現像用の固形処理剤JN1を収納室412Aに10錠、漂白用の固形処理剤JN2を収納室412Cに10錠、定着用の固形処理剤JN3を4列の収納室412Dに40錠(各分室に10錠ずつ)、安定化用の固形処理剤JN4を収納室412Eに1錠を、それぞれ投入開口部414(A〜E)から縦列に収納する。
【0050】
そして、蓋部材42の係合部421A,421Bを容器本体41のフランジ部415の両側端部415A,415Bに係合させ、案内させながら、蓋部材42を容器本体41の上方からスライドさせることにより、蓋部材42が投入開口部414(A〜E)を覆う。このとき、蓋部材42の溝部422(A〜D)は、仕切壁411(A〜D)の投入開口部414(A〜E)より突出した部分と嵌合しながら蓋部材42がスライドし、蓋部材42が投入開口部414(A〜E)を覆ったときには溝部422(A〜D)が仕切壁411(A〜D)の突出した部分と嵌合している状態を維持している。なお、このような蓋部材42をスライドさせるときには、蓋部材42の両側面に設けられた操作部材429を操作することにより行われる。
【0051】
この蓋部材42の取り付けについて、図8(b)、(c)で説明する。蓋部材42はフランジ部415の面に対して傾いた状態で、フランジ部415の上端側に押し当てる。このとき、コの字状の係合部421A,421Bには切り欠き428が設けられているので、この切り欠き428の部分を押し当てるようにする。そして、蓋部材42を立てながら下方向へ、係合部をフランジ部415の両側端部415A,415Bに係合、案内させながらスライドさせる。このように、コの字状の係合部421A,421Bに切り欠き428を設けることにより、狭い間隙しか有していない係合部421A,421Bであっても、係合部421A,421Bと両側端部415A,415Bとを掛合させる際の空間を広げているので、蓋部材42の取り付け作業を容易に行うことができる。特に、本実施の形態では、係合部421のコの字状の間隙を上端側より下端側の方が広がるように構成しているので、さらに取り付け作業の容易化を図ることができる。
【0052】
そして、蓋部材42が投入開口部414(A〜E)を完全に覆ったとき、蓋部材42の第1係止部426がフランジ部415の係止切欠416によって係止されることにより、これ以上下方向にスライドできないようになる。さらにこのとき、蓋部材42の第2係止部427がフランジ部415の下端面に係止されることにより、誤って蓋部材42が上方向にスライドしないように、所謂、ロック状態にしている。
【0053】
固形処理剤JNが収納された収納容器(容器本体41の外壁の上面側)にメーカー名や収納される固形処理剤Jの種類を表すラベルが粘着される。このラベルは、収納容器40のリサイクルなどを考慮して、容器本体41(好ましくは、さらに蓋部材42及びキャップ部材43)と同じ材質とする。すなわち、ラベル44が粘着される部材である容器本体41とラベル44とを同じ材質とすることで、産業廃棄物として廃棄されることなくリサイクルすることができ、しかも、リサイクルする際にはこれらを剥がすことなく利用でき、リサイクル作業の効率化を図ることができる。
【0054】
次に、収納容器40から固形処理剤JNの排出について説明する。この場合、蓋部材42を上方向へスライドさせればよいが、第2係止部427がフランジ部415の下端面に係止されているので、直上方向へスライドできない。そのために、図8(c)に示すように、操作部材429を一旦先端側の方向(矢示の方向)へ押すことにより、蓋部材42を撓ませて第2係止部427と下端面との係止状態を解除する。このとき、係合部421のコの字状の間隙を上端側より下端側の方が広がるように構成しているので、この解除を容易に行うことができる。そして、第2係止部427と下端面との係止状態を解除した状態で、操作部材429を上方向へ押し上げることにより、蓋部材42を上方向へスライドさせて、投入開口部414(A〜E)を開放し、投入開口部414(A〜E)から各固形処理剤JN1〜JN4を排出する。
【0055】
このように、各収納室412A,412C,412D,412Eに固形処理剤JN1〜JN4を収納している状態のときには、仕切壁411(A〜D)の投入開口部414(A〜E)より突出している部分と、蓋部材42の溝部422(A〜D)とが、嵌合しているので、例えば、収納容器40の運搬等で収納している固形処理剤JNから粉が発生したとしても、嵌合部分で遮断され、隣接する収納室に粉が入り込むことがなく、コンタミを防止することができる。なお、全ての収納室412(A〜E)の間の仕切壁411(A〜D)に、投入開口部414(A〜E)より突出する部分を設けたが、コンタミで処理性能に大きな支障を来す発色現像用に、漂白用或いは定着用の粉が入ることがないように、少なくとも、発色現像用の固形処理剤JN1を収納する収納室412Aと、漂白用の固形処理剤JN2を収納する収納室412Cとの間の仕切壁411A(あるいは、空室412Bを設けているので仕切壁411B)に、投入開口部414A、414Cより突出する部分を設ければよい。
【0056】
また、漂白用の固形処理剤JN2を収納する収納室412Cの投入開口部414Cを、該投入開口部414Cの一方側に隣接した発色現像用(異なる種類)の固形処理剤JN1を収納する収納室412Aの投入開口部414Aまでの距離が、他方に隣接した定着用(異なる種類)の固形処理剤JN3を収納する収納室412Dの投入開口部414Dまでの距離よりも長くなるように配置したので、コンタミを防止し、しかも、収納容器40をコンパクトに構成することができる。また、漂白用の固形処理剤JN2を収納する収納室412Cと、該収納室412Cに隣接した発色現像用(異なる種類)の固形処理剤JN1を収納する収納室412Aとの間に、固形処理剤を収容しない空室412Bが設けられたので、収納室412Aと収納室412Cとの間の距離を長くとることができ、コンタミを防止することができる。
【0057】
また、キャップ部材43の内面に設けられた嵌合溝431A〜431Cが、仕切壁411(A〜D)、さらに、容器本体41の外壁と嵌合し、容器本体41の後端側の開放を覆うので、容器本体41の後端側からのコンタミ、さらに、外部への粉塵の排出を防止できる。
【0058】
収納容器40は、蓋部材42を下向きにして、補給装置30の装着部にほぼ垂直に取り付けられる。
【0059】
容器本体41に外壁両側面には、収納容器40を補給装置30に装着して係止するための突起部材(支持ピン)418、419が一体に突設されている。蓋部材42に近い方の2個の突起部材418は、補給装置30の下方の装着部に設けたカム溝に嵌入され、位置決め固定される。この収納容器40の補給装置30への装着時に、蓋部材42は、図8に示すように、開放状態となる。この収納容器40の装着時に、キャップ部材43に近い方の2個の突起部材419は、補給装置30の上方の上支持部310に設けたガイド溝部312Aに嵌入され、保持凹部312Bにおいて位置決め固定される。
【0060】
図9は、収納容器40を補給装置30に装着する操作を示す斜視図、図10は収納容器40を補給装置30に装着した補給状態を示す正面図である。
【0061】
補給装置30は、収納容器40のキャップ部材43側を支持する上支持部(押圧側装填ユニット)310と、収納容器40の蓋部材42側を支持し収納容器40内の複数の固形処理剤を受容する装着部(投入側装填ユニット)320と、受容した固形処理剤を複数の処理液槽に投入する処理剤投入部330とから成る。
【0062】
上支持部310は、支柱311、支持部材312、押圧手段(セット方向付勢手段)313とから成る。支柱311は基板300に直立固定されている。支持部材312は支柱311の上部に固定されている。支持部材312の内側には、収納容器40の突起部材419を導入可能にするガイド溝部312Aと、ガイド溝部312Aの末端の保持凹部312Bとが穿設されている。押圧部材313は、収納容器40が上支持部310に装着されたとき、収納容器40の上部のキャップ部材43を押圧する。押圧部材313は、板バネまたはコイルバネに支持されたローラ、または板バネ等の付勢手段である。
【0063】
装着部320の上本体(上ハウジング)321には、収納容器40内の複数の固形処理剤を受容する投入ガイド開口部322が穿設されている。投入ガイド開口部322は複数の仕切壁(リブ)323により仕切られて、複数の開口分室を形成している。これらの複数の開口分室は、前記の容器本体41の収納室412(A〜E)にそれぞれ対応している。
【0064】
図12に示すように、複数の仕切壁323のうち、特に、容器本体41の収納室412Bと412Cとを仕切る仕切壁411Bに対向する仕切壁323Bは、他の仕切壁411より容器本体41側に突出していて、収納容器40を装着部320に装填したとき、容器本体41の仕切壁411Bの先端部に近接又は当接している。このように仕切壁323Bと仕切壁411Bを近接又は当接することにより、上方の容器本体41の収納室412(A〜E)のうち特に収納室412Bと412C内に収納された固形処理剤の粉末や小塊が、投入ガイド開口部322の対応する開口分室に隣接する開口分室内に混入することが防止される(コンタミを防止)。
【0065】
投入ガイド開口部322の上面の周辺には、収納容器パッキン327が貼着されている。収納容器40を装填部320に装填した状態では、収納容器パッキン327は容器本体41のフランジ部415に密接して、開口状態の収納容器40内に外気が侵入することを防止する。このように気密化することにより、外気、特に高湿な外気の収納容器40内への侵入による固形処理剤の膨潤が防止される。
【0066】
また、上本体321の両側壁の内側には、溝カム部324が穿設されている。溝カム部324には、収納容器40を装着部320に装着操作するとき、収納容器40の突起部418が挿入、嵌合し、蓋部材42を移動させて開放可能にする。また、収納容器40を装着部320から装脱操作するとき、収納容器40の開口部を蓋部材42により閉止させる。
【0067】
装着部320に収納容器40を装着させる操作過程を以下に示す。
【0068】
(1)蓋部材42が下側になるようにして収納容器40を把持し、突起部419を支持部材312の溝部312Aに沿わせて斜め下方から斜め上向き方向に挿入する(図9の▲1▼方向)。左右2箇所に設けられた溝部312Aは、溝幅が異なるように穿設され、左右2箇所の突起部419の各外径も、溝部312Aに合致するように設定されているから、収納容器40を逆向きに挿入することはできないようになっている(誤装填防止)。
【0069】
(2)突起部419を凹部312Bに嵌装させたのち、収納容器40を凹部312Bを中心にして揺動させると(図9の▲2▼方向)、蓋部材42の両端の操作部材429が係止部材に当接して進行が妨げられて停止し、さらに収納容器40を移動させると、容器本体41のみが移動して、投入開口部414(A〜E)が次第に開放される。
【0070】
(3)容器本体41のフランジ部415がストッパに当接すると、収納容器40の蓋部材42の近傍の突起部418が溝カム部324に嵌入して、凹部325に落ち込み、板バネ(ガイド方向付勢手段)326により押圧された状態で停止する。このとき投入開口部414(A〜E)は全開状態になり、容器本体41内の固形処理剤Jは、装着部320の開口部322内に落下する。
【0071】
図11は装着部320及び処理剤投入部330の回転軸直角方向の断面図、図12は装着部320及び処理剤投入部330の回転軸平行方向の縦断面図である。
【0072】
装着部320の下方の処理剤投入部330は、下本体(下ハウジング)331、ドラム部材333及び駆動手段等から構成されている。下本体331の下部にはシャッター手段340が揺動可能に支持されている。
【0073】
下本体331の下方には、固形処理剤Jを投下して補給する開口部(処理剤投入口)332が穿設されている。開口部332は補給時以外はシャッター手段340により閉鎖されている。シャッター部材341は下本体331の下面の円筒面に沿って揺動される。シャッター部材341の内側の凹部には、押圧部材342、弾性部材343、バネ344が収容されている。押圧部材342の上面に貼着された弾性部材343は、バネ344により付勢されて下本体331の下方の開口部332を圧着、封鎖する。シャッター部材341の他方には、複数の仕切壁を有する貫通する開口部345が穿設されていて、固形処理剤Jを通過、落下可能にしている。開口部345には、8列の固形処理剤を整列して落下させるための仕切り壁が設けてある。
【0074】
シャッター部材341は揺動板346と一体化されている。揺動板346は後述のドラム部材333を駆動回転させる回転軸に回転可能に支持され、他端はクランク347に接続している。クランク347は駆動源により回転する偏心円板348に接続して偏心移動し、揺動板346及びシャッター部材341を揺動させる。このシャッター部材341の揺動により、開口部332は開閉される。
【0075】
シャッター部材341は偏心揺動機構により、固形処理剤補給時にのみ開口部332を開放状態になし、補給時以外には、開口部332を閉止状態に保持する。補給時以外に、シャッター部材341により開口部332を閉止状態にすることにより、補給装置30の下方の処理槽から上昇する処理液蒸気の装置本体内への進入を防止し、防湿効果を高める。
【0076】
下本体331の両側面には、それぞれ回転軸334が軸受336を介して回転可能に支持されている。回転軸334の一方の軸端には、歯車335が固定されている。歯車335は図10に示す駆動源及び駆動伝達歯車列により回転される。
【0077】
各回転軸334の内側には、切り欠き円板状の凸カップリング部334Kが突出している。この凸カップリング部334Kはドラム部材333の両端面に穿設された凹カップリング部333Kに嵌合して、ドラム部材333に駆動回転を伝達する。
【0078】
ドラム部材333は複数(図示8個)の円筒部から成る。これらの円筒部は中心部のボスと半径方向のピンとにより位置決めされて一体化される。
【0079】
図13(a)はドラム部材333の側面図、図13(b)はドラム部材333の斜視図である。図14はドラム部材333のA−A,B−B,C−C,D−D,E−E,F−F,G−G,H−H各断面図である。
【0080】
ドラム部材333には、収納容器40の8列の分室に対応して、8列の円筒部材が角度位相をずらせて設けてある。各円筒部材には、1個の固形処理剤Jを受容可能な固形処理剤受容部(ポケット部)333A,333B,333C,333D,333E,333F,333G,333Hが回転方向に角度位相をずらせて穿設されている。
【0081】
自現機ANの補給装置30N内に装着されるドラム部材333の8列の円筒部材のうち、第1列のポケット部333Aには、発色現像用の固形処理剤JN1が投入される。第2列のポケット部333Bは空室、第3列のポケット部333Cには、漂白用の固形処理剤JN2が投入される。第4〜7列のポケット部部333D,333E,333F,333Gには、定着用の固形処理剤JN3が投入される。第8列のポケット部333Hには、安定化用の固形処理剤JN4が投入される。
【0082】
自現機APの補給装置30P内に装着されるドラム部材333の8列の円筒部材のうち、第1列及び第2列のポケット部333A,333Bには、発色現像用の固形処理剤JP1が投入される。第3列のポケット部333Cは空室、第4〜7列のポケット部333D,333E,333F,333Gには、漂白定着用の固形処理剤JP2が投入される。第8列のポケット部333Hには、安定化用の固形処理剤JP3が投入される。
【0083】
これらの固形処理剤のうち、特にコンタミを防止しなければならない固形処理剤JN1とJN2とは、空室333Bを介して離間しているが、各ポケット部を仕切る仕切り壁部の先端部と、上ハウジング321、下ハウジング331の内壁との隙間から固形処理剤の粉末が侵入して混合する恐れがある。
【0084】
同様にして、特にコンタミを防止しなければならない固形処理剤JP1とJPN2とは、空室333Cを介して離間しているが、各ポケット部を仕切る仕切り壁部の先端部と、上ハウジング321、下ハウジング331の内壁との隙間から固形処理剤の粉末が侵入して混合する恐れがある。
【0085】
収納容器40Nと収納容器40Pとは同一形状であるから、第2列のポケット部333Bと第3列のポケット部333Cとの間の仕切り壁の先端部にジグザグ状の突起部333Zを形成し、、上ハウジング321及び下ハウジング331の内壁の先端部に突起部333Zに係合する突起部を形成して、凹凸係合の迷路構造に構成した。この凹凸係合と空室の存在とにより、固形処理剤JN1とJN2との混入、又は固形処理剤JP1とJP2との混入が確実に防止され、かつ、ドラム部材333の回転は支障なく行われる。なお、上記の凹凸係合の迷路構造は、他の仕切り壁にも設けることが可能である。
【0086】
また、ドラム部材333の8列のポケット部333(A〜H)を仕切るフランジ部の外周面と、上ハウジング321、下ハウジング331の内壁との間に、微小な隙間を設けた。この隙間は、0.2〜0.3mmに設定されている。この隙間が少ないと、この隙間に混入した固形処理剤の粉末がドラム部材333の回転を阻害する。この隙間が多いと、隣接するポケット部から固形処理剤の粉末が侵入する。
【0087】
図15及び図16はドラム部材333のポケット部333Aから固形処理剤Jが投下される過程を示す補給装置30の断面図である。即ち、図15は収納容器40内の固形処理剤Jをドラム部材333のポケット部333Aに投入した状態の補給装置30の断面図であり、図16はドラム部材333のポケット部333Aから固形処理剤Jを処理液槽に投下する状態の補給装置30の断面図である。
【0088】
固形処理剤Jの補給開始信号により、駆動手段により図10に示す偏心円板348が回転され、クランク347が揺動板346を回転軸334を中心にして揺動運動させる。揺動板346と一体をなすシャッター部材341は揺動されて、シャッター部材341の開口部345が下ハウジング331の下部の開口部(処理剤投下口)332に合致したとき、シャッター部材341の揺動が停止する。
【0089】
シャッター部材341の揺動運動終了後に、ドラム部材333が他の駆動手段により図示の矢印方向に回転され、固形処理剤がドラム333内に受容されて回転搬送され、開口部332とシャッター部材341の開口部345とを通過して落下し、下方の処理槽内に補給される。
【0090】
ドラム部材333の回転による固形処理剤補給過程を以下に説明する。
【0091】
(1)収納容器40が補給装置30の装着部に装着されて、前記蓋部材42が自動的に開けられて、投入開口部414(A〜E)を開放状態にされたとき、容器本体41内の先頭の固形処理剤JN1〜JN4は、停止状態のドラム部材333の外周面に当接して初期の停止状態に保持される。
【0092】
(2)ドラム部材333の回転開始により、先ず、容器本体41内の投入開口部414(A〜E)から、第1列のポケット部333Aに固形処理剤JN1が、次いで第3列のポケット部333Cに固形処理剤JN2が、さらに第4列ないし第7列の各ポケット部部333D〜333Gに固形処理剤JN3が、さらに第8列のポケット部333Hに固形処理剤JN4が、それぞれ順次投入される。
【0093】
(3)引き続き、ドラム部材333の回転により、ポケット部333A,333B,333C,333D〜333G,333Hが下本体331の下方の開口部332に一致した位置に達したとき、前記ポケット部にそれぞれ収容された4種の固形処理剤JNI,JN2,JN3,JN4が順次落下して、下方の開口部332及びシャッター部材341の開口部345を通過して、下方の処理槽内に補給される。
【0094】
(4)このようにして、ドラム部材333の1回転により、発色現像用固形処理剤JN1(1錠)、漂白用固形処理剤JN2(1錠)、定着用固形処理剤JN3(4錠)、安定用固形処理剤JN4(1錠)が補給される。
【0095】
なお、上述の実施の形態は、錠剤型固形処理剤の補給装置であり、収納容器内の固形処理剤をドラム部材333の1回転で所定量を供給し、さらに収納容器を一括交換可能にしたものであるが、本発明の固形処理剤補給装置は、複数の小粒子状固形処理剤や顆粒状固形処理剤の定量補給にも適用可能である。
【0096】
【発明の効果】
以上説明したように、本発明の感光材料処理用固形処理剤補給装置は、以下の優れた効果を奏する。
【0097】
(1)処理剤投入部は、投入側装填ユニットと押圧側装填ユニットをハウジングに固定する構造であり、収納容器を支点にして回動して装填するために、処理剤投入部の耐久性が向上する(請求項1)。
【0098】
(2)収納容器の倒れが防止され、かつ収納容器の密着性が向上する(請求項2)。
【0099】
(3)ネガフィルム用とペーパー用の収納容器の誤装填、あるいは収納容器の装填方向の誤挿入はガイド溝部と支持ピンにより防止することができる(請求項3)。
【0100】
(4)収納容器を装着部に装填するとき、付勢手段により収納容器を投入開口部に圧接することにより、収納容器と装着部は確実に密接されて定置される(請求項4)。
【0101】
(5)処理槽側からのガスが収納容器内に侵入することを防止され、固形処理剤が膨潤しない(請求項5)。
【0102】

BACKGROUND OF THE INVENTION
The present invention provides a photosensitive material for supplying a predetermined amount of different types of solid processing agents stored in storage containers to a plurality of processing solution tanks of a photosensitive material processing apparatus for processing photosensitive materials. The present invention relates to a solid processing agent supply device for material processing.
[0002]
[Prior art]
A silver halide photographic light-sensitive material (hereinafter also referred to as a light-sensitive material) is processed by a processing step using a processing solution such as a developer, a bleaching solution, a fixing solution, or a stabilizing solution after exposure. This processing is usually performed by an automatic developing machine. In this case, a replenisher replenishing method is generally used, and the activity of each processing solution in the processing tank is controlled to be kept constant.
[0003]
In the replenisher replenishing method, the purpose is to dilute the processing liquid with the eluate from the photosensitive material, replenish the evaporation amount, and replenish the consumption components. As a result of the liquid replenishment, usually a large amount of overflow liquid is discharged.
[0004]
In order to carry out the processing of photosensitive materials in a commercial manner, it is stable and excellent with as little processing solution as possible in order to reduce cost and manpower, reduce pollution load, make processing equipment more compact, and improve product value. It is required to obtain high processing performance.
[0005]
As a method for meeting this demand, WO92 / 20013 discloses a method in which almost all the processing agent components are converted into solid processing agents and directly charged into a processing tank.
[0006]
However, in this method, the processing amount of the photosensitive material is detected, and a predetermined amount of different solid processing agents are individually controlled and replenished to the processing liquid in each of the plurality of processing tanks. There is a problem that the control device for controlling the amount and timing of charging becomes complicated, the probability of failure increases, and the size of the device also increases. In addition, because the consumption of different solid processing agents stored in multiple storage containers is significantly different, there is a difference in the remaining amount of solid processing agents in the storage containers, and maintenance is required to replace each storage container individually for each consumption. Operation becomes troublesome. Accordingly, there is an urgent need to develop a technology for replenishing a solid processing agent that solves these problems.
[0007]
[Problems to be solved by the invention]
An object of the present invention is to solve the following problems.
[0008]
-Conventionally, since the upper unit rotates when loading the storage container, it is not durable.
[0009]
-When loading the storage container, it is necessary to prevent the adhesion between the storage container opening and the mounting part from being impaired.
[0010]
-It is necessary to prevent erroneous loading of storage containers for negative film and paper, or erroneous insertion in the loading direction with a simple structure.
[0011]
-When the gas from the processing liquid tank enters the storage container, there is a problem that the solid processing agent swells.
[0012]
When the storage container is loaded, outside air enters from the opening of the storage container and the solid processing agent in the storage container swells.

At this time, by sticking the sealing member 35 across the cap member 43 and the container main body 41, it is possible to completely prevent the dust of the solid processing agent JN from leaking to the outside from the rear end side of the container main body 41. Yes. Next, 10 tablets of solid processing agent JN1 for color development in storage chamber 412A, 10 tablets of solid processing agent JN2 for bleaching in storage chamber 412C, and 40 tablets of solid processing agent JN3 for fixing in 4 rows of storage chambers 412D (10 tablets in each compartment), 1 tablet of the solid processing agent JN4 for stabilization is stored in the storage chamber 412E in a column from the input openings 414 (A to E).
[0050]
Then, by engaging and guiding the engaging portions 421A and 421B of the lid member 42 with both side end portions 415A and 415B of the flange portion 415 of the container body 41, the lid member 42 is slid from above the container body 41. The lid member 42 covers the input openings 414 (A to E). At this time, the groove portion 422 (A to D) of the lid member 42 slides while the lid member 42 slides while fitting with the portion protruding from the input opening 414 (A to E) of the partition wall 411 (A to D), When the lid member 42 covers the input opening 414 (A to E), the groove 422 (A to D) is kept in a state of being fitted to the protruding portion of the partition wall 411 (A to D). In addition, when sliding such a cover member 42, it is performed by operating the operation member 429 provided in the both sides | surfaces of the cover member 42. FIG.
[0051]
The attachment of the lid member 42 will be described with reference to FIGS. The lid member 42 is pressed against the upper end side of the flange portion 415 while being inclined with respect to the surface of the flange portion 415. At this time, since the notches 428 are provided in the U-shaped engaging portions 421A and 421B, the portions of the notches 428 are pressed against each other. Then, the engaging part is slid while engaging and guiding the both side end parts 415A and 415B of the flange part 415 in the downward direction while raising the lid member 42. As described above, by providing the notches 428 in the U-shaped engaging portions 421A and 421B, even if the engaging portions 421A and 421B have only a narrow gap, the engaging portions 421A and 421B and the both sides Since the space for engaging the end portions 415A and 415B is widened, the attaching operation of the lid member 42 can be easily performed. In particular, in the present embodiment, the U-shaped gap of the engaging portion 421 is configured so that the lower end side is wider than the upper end side, so that the mounting operation can be further facilitated.
[0052]
When the lid member 42 completely covers the input opening 414 (A to E), the first latching portion 426 of the lid member 42 is latched by the latching notch 416 of the flange portion 415. It will not be possible to slide downward. Further, at this time, the second locking portion 427 of the lid member 42 is locked to the lower end surface of the flange portion 415, so that the lid member 42 is in a so-called locked state so that the lid member 42 is not accidentally slid upward. .
[0053]
A label indicating the manufacturer name and the type of the solid processing agent J to be stored is adhered to the storage container (the upper surface side of the outer wall of the container body 41) in which the solid processing agent JN is stored. This label is made of the same material as the container body 41 (preferably, the lid member 42 and the cap member 43) in consideration of recycling of the storage container 40 and the like. That is, by making the container main body 41 and the label 44, which are members to which the label 44 adheres, the same material, it can be recycled without being discarded as industrial waste. It can be used without peeling off, and the efficiency of recycling work can be improved.
[0054]
Next, discharge of the solid processing agent JN from the storage container 40 will be described. In this case, the lid member 42 may be slid upward. However, since the second locking portion 427 is locked to the lower end surface of the flange portion 415, it cannot be slid directly upward. For this purpose, as shown in FIG. 8C, the operation member 429 is once pushed in the direction toward the distal end (in the direction indicated by the arrow) to bend the lid member 42, and the second locking portion 427 and the lower end surface. Release the locked state. At this time, since the U-shaped gap of the engaging portion 421 is configured so that the lower end side is wider than the upper end side, this release can be easily performed. Then, in a state where the locking state between the second locking portion 427 and the lower end surface is released, the operation member 429 is pushed upward to slide the lid member 42 upward, so that the input opening 414 (A To E), and the solid processing agents JN1 to JN4 are discharged from the input openings 414 (A to E).
[0055]
As described above, when the solid processing agents JN1 to JN4 are stored in the storage chambers 412A, 412C, 412D, and 412E, the storage chambers 412A, 412C, 412D, and 412E protrude from the input openings 414 (A to E) of the partition walls 411 (A to D). And the groove portion 422 (A to D) of the lid member 42 are fitted to each other. For example, even if powder is generated from the solid processing agent JN stored by transporting the storage container 40 or the like. , It is blocked at the fitting portion, and powder does not enter the adjacent storage chamber, and contamination can be prevented. Although the partition walls 411 (A to D) between all the storage chambers 412 (A to E) are provided with portions that protrude from the input openings 414 (A to E), the contamination greatly affects processing performance. In order to prevent bleaching or fixing powder from entering, the storage chamber 412A for storing the color developing solid processing agent JN1 and the bleaching solid processing agent JN2 are stored. The partition wall 411A (or the partition wall 411B because the empty chamber 412B is provided) between the storage chamber 412C and the storage chamber 412C to be provided may be provided with a portion protruding from the input openings 414A and 414C.
[0056]
In addition, a loading opening 414C of the storage chamber 412C for storing the solid processing agent JN2 for bleaching is used as a storage chamber for storing the color processing (different types) solid processing agent JN1 adjacent to one side of the charging opening 414C. Since the distance to the input opening 414A of 412A is longer than the distance to the input opening 414D of the storage chamber 412D that stores the fixing (different kind) solid processing agent JN3 adjacent to the other, Contamination can be prevented and the storage container 40 can be made compact. Further, a solid processing agent is placed between the storage chamber 412C for storing the bleaching solid processing agent JN2 and the storage chamber 412A for storing the color developing (different kind) solid processing agent JN1 adjacent to the storage chamber 412C. Since the vacant room 412B that does not contain the space is provided, the distance between the storage room 412A and the storage room 412C can be increased, and contamination can be prevented.
[0057]
Further, the fitting grooves 431A to 431C provided on the inner surface of the cap member 43 are fitted to the partition walls 411 (A to D) and the outer wall of the container body 41 to open the rear end side of the container body 41.

FIG. 9 is a perspective view illustrating an operation of mounting the storage container 40 to the replenishing device 30, and FIG. 10 is a front view illustrating a replenishment state in which the storage container 40 is mounted to the replenishing device 30.
[0061]
The replenishing device 30 supports an upper support portion (pressing side loading unit) 310 that supports the cap member 43 side of the storage container 40 and a plurality of solid processing agents in the storage container 40 that support the lid member 42 side of the storage container 40. It comprises a receiving portion (input side loading unit) 320 for receiving and a processing agent input portion 330 for supplying the received solid processing agent into a plurality of processing liquid tanks.
[0062]
The upper support portion 310 includes a column 311, a support member 312, and a pressing unit (set direction biasing unit) 313. The column 311 is fixed upright on the substrate 300. The support member 312 is fixed to the upper part of the column 311. Inside the support member 312, a guide groove 312A that allows the protrusion member 419 of the storage container 40 to be introduced, and a holding recess 312B at the end of the guide groove 312A are formed. The pressing member 313 presses the cap member 43 at the top of the storage container 40 when the storage container 40 is mounted on the upper support portion 310. The pressing member 313 is a roller supported by a leaf spring or a coil spring, or an urging means such as a leaf spring.
[0063]
An upper guide body (upper housing) 321 of the mounting portion 320 is provided with an input guide opening 322 for receiving a plurality of solid processing agents in the storage container 40. The charging guide opening 322 is partitioned by a plurality of partition walls (ribs) 323 to form a plurality of opening compartments. The plurality of opening compartments correspond to the storage chambers 412 (A to E) of the container body 41, respectively.
[0064]
As shown in FIG. 12, among the plurality of partition walls 323, in particular, the partition wall 323 B facing the partition wall 411 B that partitions the storage chambers 412 B and 412 C of the container body 41 is closer to the container body 41 than the other partition walls 411. When the storage container 40 is loaded in the mounting part 320, the container 40 is close to or in contact with the tip of the partition wall 411B of the container body 41. In this way, by bringing the partition wall 323B and the partition wall 411B close to or in contact with each other, the powder of the solid processing agent stored in the storage chambers 412B and 412C among the storage chambers 412 (A to E) of the upper container body 41 in particular. Or small lumps are prevented from entering the opening compartment adjacent to the corresponding opening compartment of the charging guide opening 322 (contamination is prevented).
[0065]
A storage container packing 327 is attached to the periphery of the upper surface of the charging guide opening 322. In a state where the storage container 40 is loaded in the loading unit 320, the storage container packing 327 is in close contact with the flange portion 415 of the container main body 41 to prevent outside air from entering the open storage container 40. By being airtight in this manner, swelling of the solid processing agent due to intrusion of outside air, particularly high humidity outside air, into the storage container 40 is prevented.
[0066]
Further, a groove cam portion 324 is formed inside the both side walls of the upper main body 321. When the storage container 40 is mounted on the mounting section 320, the groove cam section 324 is inserted and fitted with the projection 418 of the storage container 40, and the lid member 42 is moved to be opened. Further, when the storage container 40 is removed from the mounting portion 320, the opening of the storage container 40 is closed by the lid member 42.
[0067]
An operation process for mounting the storage container 40 on the mounting portion 320 will be described below.
[0068]

The groove portions 312A provided at the two left and right locations are formed so as to have different groove widths, and the outer diameters of the projection portions 419 at the two left and right locations are set to match the groove portions 312A. Cannot be inserted in the opposite direction (preventing misloading).
[0069]
(2) After fitting the protrusion 419 into the recess 312B and then swinging the storage container 40 about the recess 312B (direction (2) in FIG. 9), the operation members 429 at both ends of the lid member 42 are moved. When the storage container 40 is moved by stopping the movement by contacting the locking member and stopped, only the container body 41 is moved, and the input openings 414 (A to E) are gradually opened.
[0070]
(3) When the flange portion 415 of the container body 41 comes into contact with the stopper, the projection 418 near the lid member 42 of the storage container 40 is fitted into the groove cam portion 324 and falls into the recess 325, and the leaf spring (guide direction) The urging unit 326 stops in a state of being pressed. At this time, the input openings 414 (A to E) are fully opened, and the solid processing agent J in the container main body 41 falls into the openings 322 of the mounting part 320.
[0071]
11 is a cross-sectional view of the mounting unit 320 and the processing agent charging unit 330 in the direction perpendicular to the rotation axis, and FIG. 12 is a vertical cross-sectional view of the mounting unit 320 and the processing agent charging unit 330 in the direction parallel to the rotation axis.
[0072]
The processing agent charging unit 330 below the mounting unit 320 includes a lower main body (lower housing) 331, a drum member 333, driving means, and the like. A shutter unit 340 is swingably supported at the lower portion of the lower main body 331.
[0073]
Below the lower main body 331, an opening (processing agent charging port) 332 for dropping and replenishing the solid processing agent J is formed. The opening 332 is closed by shutter means 340 except during replenishment. The shutter member 341 is swung along the cylindrical surface of the lower surface of the lower main body 331. A pressing member 342, an elastic member 343, and a spring 344 are accommodated in the concave portion inside the shutter member 341. The elastic member 343 attached to the upper surface of the pressing member 342 is urged by the spring 344 to crimp and seal the opening 332 below the lower main body 331. On the other side of the shutter member 341, a through opening 345 having a plurality of partition walls is formed so that the solid processing agent J can pass through and fall. The opening 345 is provided with partition walls for aligning and dropping the eight rows of solid processing agents.
[0074]
The shutter member 341 is integrated with the swing plate 346. The swing plate 346 is rotatably supported by a rotating shaft that drives and rotates a drum member 333 described later, and the other end is connected to a crank 347. The crank 347 is connected to an eccentric disk 348 that is rotated by a drive source and moves eccentrically, thereby causing the rocking plate 346 and the shutter member 341 to rock. The opening 332 is opened and closed by the swing of the shutter member 341.
[0075]
The shutter member 341 uses an eccentric swing mechanism to open the opening 332 only when the solid processing agent is replenished, and holds the opening 332 closed when not supplying. In addition to the time of replenishment, the opening 332 is closed by the shutter member 341, thereby preventing the processing liquid vapor rising from the treatment tank below the replenishing device 30 from entering the apparatus main body and enhancing the moisture-proof effect.
[0076]
Rotating shafts 334 are rotatably supported on both side surfaces of the lower main body 331 via bearings 336, respectively. A gear 335 is fixed to one end of the rotary shaft 334. The gear 335 is rotated by a drive source and a drive transmission gear train shown in FIG.
[0077]
A notch disk-like convex coupling portion 334K protrudes inside each rotating shaft 334. The convex coupling portion 334K is fitted into a concave coupling portion 333K formed in both end surfaces of the drum member 333, and transmits driving rotation to the drum member 333.
[0078]
The drum member 333 includes a plurality of (eight illustrated) cylindrical portions. These cylindrical portions are positioned and integrated by a central boss and a radial pin.
[0079]
FIG. 13A is a side view of the drum member 333, and FIG. 13B is a perspective view of the drum member 333. FIG. 14 is a cross-sectional view of the drum member 333 taken along the lines AA, BB, CC, DD, EE, FF, GG, and HH.
[0080]
The drum member 333 is provided with eight rows of cylindrical members that are out of phase with respect to the eight rows of compartments of the storage container 40. In each cylindrical member, solid processing agent receiving portions (pocket portions) 333A, 333B, 333C, 333D, 333E, 333F, 333G, and 333H that can receive one solid processing agent J are shifted in angular phase in the rotation direction. It has been drilled.
[0081]
Of the eight rows of cylindrical members of the drum member 333 mounted in the replenishing device 30N of the automatic machine AN, the solid processing agent JN1 for color development is charged into the first row of pocket portions 333A. The second row of pocket portions 333B is vacant, and the third row of pocket portions 333C is charged with the solid processing agent JN2 for bleaching. The solid processing agent JN3 for fixing is put into the pocket portions 333D, 333E, 333F, and 333G in the fourth to seventh rows. A solid processing agent JN4 for stabilization is charged into the pocket portion 333H in the eighth row.
[0082]
Of the eight rows of cylindrical members of the drum member 333 mounted in the replenishing device 30P of the actual machine AP, the first and second rows of pocket portions 333A and 333B contain a solid processing agent JP1 for color development. It is thrown. The third row of pocket portions 333C is empty, and the fourth to seventh rows of pocket portions 333D, 333E, 333F, and 333G are charged with a solid processing agent JP2 for bleach-fixing. A solid processing agent JP3 for stabilization is charged into the pocket portion 333H in the eighth row.
[0083]
Among these solid processing agents, the solid processing agents JN1 and JN2 that must particularly prevent contamination are spaced apart through the empty chamber 333B, but the front end portion of the partition wall that partitions each pocket portion, There is a risk that the powder of the solid processing agent may enter and mix from the gap between the inner wall of the upper housing 321 and the lower housing 331.
[0084]
Similarly, the solid processing agents JP1 and JPN2, which must be prevented from contamination, are spaced apart through the empty chamber 333C, but the front end portion of the partition wall that partitions each pocket portion, the upper housing 321, and the like. There is a possibility that the powder of the solid processing agent may enter through the gap with the inner wall of the lower housing 331 and mix.
[0085]
Since the storage container 40N and the storage container 40P have the same shape, a zigzag protrusion 333Z is formed at the tip of the partition wall between the second row of pocket portions 333B and the third row of pocket portions 333C. The protrusions that engage with the protrusions 333Z are formed at the front end portions of the inner walls of the upper housing 321 and the lower housing 331, thereby forming a labyrinth structure with uneven engagement. Due to the uneven engagement and the presence of the vacancy, mixing of the solid processing agents JN1 and JN2 or mixing of the solid processing agents JP1 and JP2 is reliably prevented, and the drum member 333 can be rotated without any trouble. . Note that the above-described labyrinth engagement maze structure can also be provided on other partition walls.
[0086]
Further, a minute gap is provided between the outer peripheral surface of the flange portion that partitions the eight rows of pocket portions 333 (A to H) of the drum member 333 and the inner walls of the upper housing 321 and the lower housing 331. This gap is set to 0.2 to 0.3 mm. When the gap is small, the solid processing agent powder mixed in the gap inhibits the rotation of the drum member 333. If this gap is large, the powder of the solid processing agent enters from the adjacent pocket portion.
[0087]
15 and 16 are cross-sectional views of the replenishing device 30 showing a process in which the solid processing agent J is dropped from the pocket portion 333A of the drum member 333. 15 is a cross-sectional view of the replenishing device 30 in a state in which the solid processing agent J in the storage container 40 is charged into the pocket portion 333A of the drum member 333, and FIG. 16 is a solid processing agent from the pocket portion 333A of the drum member 333. It is sectional drawing of the replenishment apparatus 30 of the state which drops J to a process liquid tank.
[0088]
In response to the supply start signal of the solid processing agent J, the eccentric disk 348 shown in FIG. 10 is rotated by the driving means, and the crank 347 swings the swing plate 346 around the rotation shaft 334. When the shutter member 341 integrated with the swing plate 346 is swung, and the opening 345 of the shutter member 341 matches the opening (processing agent dropping port) 332 of the lower housing 331, the shutter member 341 swings. The movement stops.
[0089]
After the end of the swinging motion of the shutter member 341, the drum member 333 is rotated in the direction of the arrow shown in the figure by other driving means, and the solid processing agent is received in the drum 333 and rotated and conveyed, and the opening 332 and the shutter member 341 are moved. It falls through the opening 345 and is replenished into the lower processing tank.
