上記の各実施形態において、インク筒部46のインク収容室90は、高さ方向にわたって水平断面積がほぼ一定となるように構成されている。これに対して、インク筒部46のインク収容室90は、高さ方向にわたって水平断面積がほぼ一定でなくてもよく、一部に水平断面積が異なる部位を含む構成を有していてもよい。あるいは、インク筒部46のインク収容室90は、一部または全体において、水平断面積が高さ方向に減少または増大していく構成を有していてもよい。インク筒部46は、少なくとも、インクが検出される検出部位の高さ位置において、対応する高さ位置におけるインクタンク43のインク収容室70の水平断面積よりも小さければよい。
上記の各実施形態において、インク筒部46はインク注入部93を備えている。これに対して、インク筒部46は、インク注入部93を備えていなくてもよい。上記の各実施形態において、インク筒部46のインク注入部93にはキャップ部材94が取り付けられている。これに対して、インク注入部93のキャップ部材94は省略されてもよい。上記の各実施形態において、インク筒部46の第3面部83は、インク収容室90におけるインクの液面の位置を外部から視認可能な視認部として構成されている。これに対して、インク筒部46は、第3面部83のような、インクの液面の位置を外部から視認可能に構成されている部位を有していなくてもよい。また、インク筒部46では、視認部である第3面部83に、2つのマーク部95a,95bが設けられている。2つのマーク部95a,95bは、両方とも省略されてもよいし、いずれか一方のみ省略されてもよい。また、インクの液面の上限位置または下限位置を示すマーク部95a,95bの代わりに、インク量を示す目盛りが形成されていてもよい。
上記の各実施形態において、インク筒部46のインク流通部91は、インク筒部46の下端に設けられている。これに対して、インク流通部91は、インク筒部46の下端に設けられていなくてもよい。インク流通部91は、対応するインクタンク43からのインクをインク収容室90へと流入可能な位置に形成されていればよく、インク収容室90のインクが、インクタンク43の方へと流出可能な位置に設けられていることが望ましい。
上記の各実施形態では、端子接続部48および光センサー部106は、複数のインク筒部46のそれぞれに対向するように配置される基板部50を備えている。これに対して、端子接続部48および光センサー部106は、基板部50を備えていなくてもよい。端子接続部48は、各インク筒部46が備える一対の端子ピン96a,96bのそれぞれに対して一つずつ分離して設けられていてもよい。同様に、光センサー部106の発光素子107および受光素子108の組は、複数のインク筒部46のそれぞれに対して一つずつ分離して配置されていてもよい。
上記実施形態のタンクユニット40において、インクタンク43は、他の構成を有していてもよい。インクタンク43は、インク注入部72を備えていなくてもよい。インクタンク43は、大気収容室71を備えていなくてもよいし、大気連通路74を備えていなくてもよい。インクタンク43は、大気収容室71および大気連通路74のいずれか一方のみを備える構成であってもよいし、大気導入部76が直にインク収容室70に接続されている構成であってよい。インクタンク43は、インク収容室70の下端部位70bを有していなくてもよい。インクタンク43において、インク供給部73とインク流通部75とは並列に設けられていなくてもよく、それぞれが別々の方向に突出していてもよい。また、インク供給部73とインク流通部75とが異なる高さ位置に設けられていてもよい。
上記実施形態のタンクユニット40は、同じ容積の同じ形状を有する複数のインクタンク43を備えている。これに対して、タンクユニット40は、容積が異なる複数のインクタンク43を備えていてもよい。また、上記実施形態のタンクユニット40では、複数のインクタンク43は一列に配列されている。これに対して、インクタンク43は一列に配列されていなくてもよい。複数のインクタンク43は、例えば、二列に配列されていてもよいし、それぞれが分散して配置されていてもよい。
上記第4実施形態(図16)では、制御部21は、第1端子ピン110aの下端部110tよりインクの液面が低下し、信号処理部22が閾値以上の抵抗の増大を検出したときに、インクタンク43Aにおけるインク不足を検出している。これに対して、制御部21は、第4実施形態のタンクユニット40Dの構成において、第1端子ピン110aと第2端子ピン110bとの間の抵抗の変化に基づいて、インクタンク43Aに収容されているインク量を検出してもよい。このインク量の検出は、例えば、以下のような構成によって可能である。制御部21は、第1端子ピン110aと第2端子ピン110bとの間の抵抗と、インクタンク43Aのインク収容室70におけるインクの液面の位置と、の間の一意の関係が設定されたマップを不揮発性記憶装置などから予め読み込んでおく。制御部21は、信号処理部22によって第1端子ピン110aと第2端子ピン110bとの間の抵抗を検出したときに、前記のマップを参照して、検出された現在の抵抗に対するインクの液面の位置を取得する。このような構成であれば、インクタンク43Aに収容されているインク量を検出することが可能である。なお、このようなインク量を検出する構成の場合には、インク収容室70において各端子ピン110a,110bが配置されている範囲全体が、本発明における検出部位の下位概念に相当する。インクの検出部によってインク量が検出される構成である場合には、インク筒部46のインク収容室90における水平断面積は、インクの液面の位置が検出されている範囲にわたって、対応するインクタンク43のインク収容室70における水平断面積よりも小さいことが望ましい。
上記の第2実施形態では、インク筒部46Aのインク収容室90は、チューブ103を介して、インクタンク43Bの大気収容室71に接続されている(図13)。これに対して、インク筒部46Aのインク収容室90は、チューブ103を介して、インクタンク43Bのインク収容室70の上方の領域に接続されていてもよい。この構成によれば、ユーザーがインク注入部93からインク筒部46Aにインクを補充する場合に、上限を超えて過剰に注入されたインクを、チューブ103を介して、インクタンク43Aのインク収容室70へと流入させることも可能である。
上記各実施形態では、タンクユニット40は、複数のインクタンク43を備え、インクを消費可能なプリンター10に当該インクを供給可能に構成されている。これに対して、上記各実施形態におけるタンクユニット40の構成は、インク以外の他の液体を消費可能な液体消費装置に当該液体を供給可能なタンクユニットに適用されてもよい。例えば、液体洗剤を噴射する洗剤噴射装置に洗剤を供給する洗剤タンクを備えるタンクユニットに適用されてもよい。なお、プリンター10のように、液体を吐出あるいは噴射して液体を消費する液体消費装置は、液体噴射装置の一実施形態でもある。
