図1に示すように、プリンター11は、装置本体12と、装置本体12に対して鉛直方向Zの反重力方向側(上方向側)に連結して搭載された画像読取装置としてのスキャナーユニット13と、によって構成されている。装置本体12は、複数の部材で構成されたプリンター11の筐体の一例である装置ケース14によって構成され、この装置ケース14によって囲まれた空間領域内に、用紙Pへインクを噴射する液体噴射部20が備えられる。
図5に示すように、本実施例の移動機構80Aは、外周に螺旋ねじ81aが設けられた回転軸81と、この螺旋ねじ81aに噛み合うラック歯82aおよび所定の間隔を有して立設された2本の柱状部82bが設けられたスライド部材82と、を有している。また、移動機構80Aは、リンク機構を構成する棒状のリンク部材83,84,85を有している。すなわち、装置ケース14などに固定された固定軸J1を中心に回動するリンク部材84と、同じく装置ケース14などに固定された固定軸J2を中心に回動するリンク部材85とを備えている。固定軸J1,J2は前後方向において所定の間隔をあけて設けられる。さらに、リンク部材84の一端に設けられた回転軸84aとリンク部材85の一端に設けられた回転軸85aとにおいて連結されたリンク部材83を備えている。回転軸84a,85aは、リンク部材83を前後方向に移動したとき、リンク部材84とリンク部材85とが互いに平行な状態を維持しながら回動する位置に設けられている。
図6に示すように、本実施例の移動機構80Bは、回転軸16Jを中心にして前面カバー16と一体で回転するとともに、回転軸16Jとは反対側の端部に丸ピン16Pが設けられたレバー部材16Lと、前端部において丸ピン16Pと係合する係合孔72Hが設けられたタンクホルダー72Bとを有している。
図7に示すように、本実施例の移動機構80Cは、インクタンク75を少なくともその前後方向において保持する幅方向Xから見て略L字形状のタンクホルダー72Cと、上面に複数のコロ71Rが設けられたホルダー支持台71Cとを有している。そして、タンクホルダー72Cは、コロを介してホルダー支持台71C上に載置され、ユーザーが、タンクホルダー72Cの前方に設けられた取手72Tを把持して容易にホルダー支持台71Cに沿って前後に移動可能とされている。なお、タンクホルダー72Cの下面には略三角形状の係合溝72Kが設けられ、この係合溝72Kに対してホルダー支持台71Cの上面から変位可能に突設された略三角形状の係合爪71Kが進入することによって、タンクホルダー72Cの後方への移動を許容しつつ、前方へ引き出される移動量を規制する。
図8に示すように、本実施例の移動機構80Dは、例えば、前面カバー16と一体で形成されるなどにより前面カバー16の回転軸16Jを中心にして前面カバー16と一体で回転するタンクホルダー72Dと、一部が円弧形状で形成されたインクタンク75と、を有している。インクタンク75の形状は、回転軸16Jを中心として回転したとき、前面カバー16が覆う開口部から前方への移動が可能な形状(ここでは略扇形形状)で形成されている。
図9に示すように、本実施例の移動機構80Eは、ケース壁部14aに設けられた鉛直方向に軸線を有する回転軸37を中心に回転する回転部72Rが形成されたタンクホルダー72Eを有している。また、ホルダー支持台71は、回転軸37を中心とするタンクホルダー72Eの回転を妨げることない状態で設けられている。
ユーザーは、例えば、インクの消費によってインクタンク75内に収容されたインクの残量が少なくなったことを、閉じられた状態の前面カバー16の透視領域16Tを介して視認すると、移動機構を動作させる。すなわち、前面カバー16を回転させたり、あるいは前面カバー16を回転させた後にタンクホルダー72を移動させたりすることによってインクタンク75を後方から前方へ移動させる。これにより、インクタンク75は、前面カバー16が回転されることによって開放された開口部から前方に飛び出し、インクタンク75の注入口77を含む第1の部分は、例えば注入口77が開口部を介して視認できる状態でプリンター11の装置ケース14外に位置する。なお、ここでは、注入口77が視認できる状態とは、注入口77からインクの注入が可能な状態である。
(1)プリンター11において、前面カバー16を開蓋状態にすれば、例えば注入口77がインクの注入作業が容易な位置に変位するように、インクタンク75の第1の部分を移動させることができるので、注入口77からインク室75S内へインクを容易に流入させることができる。また、前面カバー16を閉蓋状態とすることによってインクタンク75への埃の堆積が抑制される。
(4)プリンター11において、比較的簡単な構造によって実現可能である回転移動によって、注入口77をインクの注入作業が容易な位置に変位させることが可能となる。

図15に示すように、本実施例の保持構造は、タンクケース79において、インクタンク75を、タンクケース79の幅方向Xの一方の開口端部において回転自在に軸支された回転軸75Jを中心に、鉛直方向を軸線として水平方向に回転移動つまり揺動可能に保持する。従ってタンクケース79は幅方向Xにおいて、揺動するインクタンク75がタンクケース79とは干渉しない長さを有して形成されている。
ユーザーは、例えば、インクの消費によってタンクケース79に収納されたインクタンク75内のインク残量が少なくなったことを、ラベル76の上部表面75aまたは下部表面75b(図3参照)を透して視認すると、インクタンク75を移動させる。すなわち、インクタンク75をタンクケース79から直線移動や回転移動によって後方から前方へ移動させる。これにより、インクタンク75の注入口77を含む第1の部分はタンクケース79外へ飛び出し、例えば上方から視認できる状態に露出させる。
(7)タンクユニット70において、タンクケース79に対して注入口77を含む第1の部分を変位させることによって、注入口77をインクの注入作業が容易な位置に変位させることができるので、注入口77からインク室75S内へインクを容易に流入させることができる。
(10)タンクユニット70において、インクタンク75を、比較的簡単な構造によって実現可能である回転によって移動させることによって、注入口77をインクの注入作業が容易な位置に変位させることが可能となる。
次に、第3実施形態の液体収容体について説明する。なお、第3実施形態の説明において、上記第1実施形態のプリンター11および第2実施形態のタンクユニット70と同じ構成要素については同符号を付し、それらについての説明は適宜省略する。
図16(a)に示すように、本実施例の変位構造は、インクタンク75において、注入口77を含む第1の部分としての変位部77hが、第1の部分とは異なる第2の部分としてのタンク本体部75hに対して排出方向Yに沿ってスライド可能に取り付けられている。そして、変位部77hとタンク本体部75hとの間には、注入口77からタンク本体部75h内に設けられたインク室75Sへのインクの流動を可能とするチューブの一例である連結チューブ97が接続されている。
図18(a)に示すように、本実施例の変位構造は、注入口77を含む第1の部分としての変位部77hが、第1の部分とは異なる第2の部分であるタンク本体部75hに対して伸長するように変位する。すなわち、変位部77hは、互いに相対移動可能な複数(ここでは3つ)の部材で構成され、この複数の部材、すなわち第1部材77a、第2部材77b、および第3部材77cを、インクタンク75において注入口77を含む第1の部分として有している。
図19(a)に示すように、本実施例の変位構造は、インクタンク75において、注入口77を含む第1の部分としての変位部77hが、第1の部分とは異なる第2の部分としてのタンク本体部75hに対して、注入口77が露出しない状態で取り付けられている。なお、本実施例では、変位部77hは、タンク本体部75hの排出方向Y側となる前側面に取り付けられている。
ユーザーは、例えば、インクタンク75内のインク残量が少ないことを、ラベル76の上部表面75aまたは下部表面75b(図3参照)を透して視認すると、注入口77を変位させる。すなわち、注入口77を直線移動や回転移動などによって移動させる。この移動によって、注入口77はインクの注入が可能な状態に露出するとともに、インクの注入が容易な位置に変位する。
(15)注入口77をインクの注入作業が容易な位置に変位させることができるので、インクタンク75において、注入口77からインク室75S内へインクを容易に流入させることができる。
・上記第3実施形態において、一つのインクタンク75に複数の注入口77が設けられるようにしてもよい。換言すれば、一つのインクタンク75に複数のインク室75Sが設けられるようにしてもよい。
(19)プリンター11において、複数の注入口77A,77Bを装置ケース14外へ位置させるので、複数の注入口77A,77Bをインクの注入作業が容易な位置に変位させることができる。
(20)タンクユニット70において、注入口77が複数設けられていても、複数の注入口77A,77Bをタンクケース79の外部へ移動させるので、インクの注入作業が容易な位置に変位させることができる。
・上記第2実施形態のタンクユニット70において、インクタンク75の注入口77は、インクが注入可能な位置であれば、必ずしもタンクケース79外へ移動するまで変位しなくても差し支えない。すなわち、上記第2実施形態では、注入口77の少なくとも一部がタンクケース79外へ移動した状態も、タンクケース79外へ移動した状態に含まれる。
・上記第2実施形態のタンクユニット70において、インクタンク75は、注入口77がインクを注入しない非注入時(通常使用状態)において必ずしもタンクケース79内に位置しなくてもよい。すなわち、インクタンク75の保持構造は、注入口77をタンクケース79に対して相対的に移動させ、インクの注入が困難な位置からインクの注入が容易な位置へ変位させる構成であってもよい。
