Description
図1に示すように、印刷装置1Aは略直方体状である。カセット1Bは、印刷装置1Aに対して前側から着脱可能に装着される。印刷装置1Aは、筐体11を有する。筐体11は、前筐体12、後筐体13を備える。後筐体13は、ベースプレート21に対して後側に設けられる(図2参照)。図1、図2に示すように、後筐体13は、それぞれ板状の上部分13U、底部分13B、側部分13R、13Lを有する。上部分13U、底部分13B、及び側部分13R、13Lのそれぞれの前端は、後筐体13の前側に開口部を形成する。ベースプレート21は、後筐体13の開口部に前側から嵌る。後筐体13は、ベースプレート21の後側に設けられたモータ31A、31D(図2、図3参照)を覆う。
図4に示すように、カセット1Bは、把手9A、板9B、及びシャフト32A~32Eを有する。板9Bは、正面視矩形の板状の基部である。把手9Aは、板9Bの前面の左右方向の中心に設けられる。シャフト32A~32Eは、それぞれ、板9Bの後面から後側に向けて延びる。
シャフト32A、32Dは同一構成であり、以下、シャフト32Aを例に挙げて具体的に説明し、シャフト32Dの説明は省略する。図5に示すように、シャフト32Aは、軸4、ナット7A、平ワッシャ7B、7E、7F、波形スプリングワッシャ7C、7D、柱6、ボルト3、回転体5、係合棒8A、8B、コイルばね84A、84B等を有する。
軸4は、後述する回転体5に挿通されて、回転体5の支軸となる部材である。軸4は、板9Bに設けられ、板9Bの後面から後側に延びる(図8参照)。軸4は、挿入部41、軸壁部42、前部突出部43、中央突出部44、及び後部突出部45を有する。挿入部41、軸壁部42、前部突出部43、中央突出部44、及び後部突出部45は、何れも前後方向に延びる略円柱状であり、且つ前後方向に延びる回転中心を有する。軸4の回転中心を「回転中心4X」と定義する。
図7に示すように、柱6は、略円柱形状を有する。柱6は、後面61、前面62、及び側面63を有する。後面61及び前面62は、円柱の底面である。後面61には、ボルト3の頭部3Aが接触する。後面61の中心には、柱6を前後方向に貫通する貫通穴64が設けられる。貫通穴64には、ボルト3のねじ部3Bが挿通される。以下、貫通穴64の中心を通って前後方向に延びる仮想軸を、「基準軸6X」という。基準軸6Xは、柱6を介して軸4の穴45Aにボルト3が螺合された状態で、軸4の回転中心4Xと一致する。
回転体5は、軸4の周りに設けられる。すなわち、軸4の軸方向と、回転体5の軸方向は一致する。同様に、軸4の径方向と回転体5の径方向は一致する。回転体5は、リボンロール20に挿通される。図5、図8に示すように、回転体5は、前部回転体51、中央回転体52、後部回転体53を有する。前部回転体51は、フランジ51A、円筒部51Bを有する。フランジ51Aの径は、リボンロール20のスプール20Aの径よりも大きい。円筒部51Bは、フランジ51Aの後端に設けられる。円筒部51Bは、前後方向に延びる円柱状である。
図5に示すように、板9Bとナット7Aの間には、ワッシャ部7Gが軸4の挿入部41に挿通されて設けられる。ワッシャ部7Gのうち、平ワッシャ7B、7E、7Fは樹脂製であり、波形スプリングワッシャ7C、7Dは金属製である。平ワッシャ7Bは、波形スプリングワッシャ7Cの付勢力により、ナット7Aの後面に押し付けられる。平ワッシャ7E、7Fは、波形スプリングワッシャ7Dの付勢力により、板9Bの前面に押し付けられる。波形スプリングワッシャ7C、7Dは、互いの付勢力により、波形スプリングワッシャ7Cの後面と波形スプリングワッシャ7Dの前面が互いに押し付けられる。
図8に示すように、回転体5は、ナット7A、ワッシャ部7Gにより板9Bに軸支された状態の軸4に取り付けられる。軸4の中央突出部44には、ベアリング4D、止め輪4Fが挿通されている。回転体5は、軸4の後側から挿通される。回転体5に嵌合されたベアリング4Cは、軸4の前部突出部43を受ける。ベアリング4Cの前端が軸4の軸壁部42の後面に接触した状態で、軸4の後部突出部45の後端は回転体5の穴53Bの底面よりも後側に配置される。以下、図8、図9に示すベアリング4Cの前面が軸壁部42の後面に接触する位置を「第一位置」という。穴53Bの底面から後方に突出する後部突出部45の後端に、柱6の溝65Aが嵌合される。ボルト3のねじ部3Bが柱6の貫通穴64を挿通し、後部突出部45の穴45Aに螺合されることで、柱6が軸4に固定される。
図8~図10を参照し、カセット1Bにおけるリボンロール20の取り外しについて説明する。シャフト32A、32Dがリボンロール20に挿通された状態で、リボンロール20がシャフト32A、32Dによって支持されているものとする。シャフト32Aと同一構成であるシャフト32Dの説明は省略する。カセット1Bが印刷装置1Aに装着されている状態(図8参照)から、カセット1Bが印刷装置1Aから前側に引き抜かれる(図9参照)。
カセット1Bは印刷装置1Aに装着されておらず、シャフト32A、32Dにリボンロール20が挿通されておらず、回転体5は第一位置にあるものとする。シャフト32Aと同一構成であるシャフト32Dの説明は省略する。回転体5が第一位置にあるので、支持部材70A、70Bは支持状態である。ユーザは、シャフト32Aの後側からリボンロール20を回転体5に挿通する。支持部材70A、70Bが支持状態であるので、貫通穴20Bの壁面に接触する。支持部材70A、70Bは、回転体5の径方向に弾性変形可能な板バネであるので、ユーザがリボンロール20を更に前側に押し付けると、リボンロール20は支持部材70A、70Bを摺動しながら回転体5の前側に移動する。リボンロール20は、前部回転体51のフランジ51Aの後面に接触して、回転体5に取り付けられる。該時、リボンロール20は、支持部材70A、70Bにより支持されている。
カセット1Bが印刷装置1Aに装着されていない場合におけるシャフト32A、32Dの動作概要について説明する。シャフト32A、32Dにリボンロール20が挿通されているものとする。シャフト32Aと同一構成であるシャフト32Dの説明は省略する。
カセット1Bは、板9B、軸4、回転体5、支持部材70A、70Bを有する。軸4は、板9Bの後面から後側に向けて突出する。軸4は、回転体5に挿通される。回転体5は、インクリボン2が巻回されたリボンロール20に挿通される。回転体5は、軸4周りに回転可能である。回転体5は、軸4に沿って、第一位置と第一位置よりも板9Bから離隔した第二位置との間を前後方向に移動可能である。支持部材70A、70Bは、回転体5に設けられる。支持部材70A、70Bは、回転体5の前後方向の移動に応じて、軸4の径方向に移動可能である。回転体5が第一位置にある場合に、支持部材70A、70Bの一部が回転体5に外接する仮想円柱Cの側面の外側に移動する。支持部材70A、70Bは、リボンロール20に内側から接触してリボンロール20を支持する支持状態となる。回転体5が第二位置にある場合に、支持部材70A、70Bの全体が仮想円柱Cの側面の内側に移動する。支持部材70A、70Bは、リボンロール20から離隔して支持を解除する離隔状態となる。このように、回転体5が板9Bから離隔する方向に移動されることで支持部材70A、70Bによるリボンロール20の支持が解除される。リボンロール20は、板9Bから離隔する方向に移動されて、回転体5から取り外される。支持部材70A、70Bによるリボンロール20の支持を解除する為の回転体5の移動方向5Zと、支持部材70A、70Bによる支持が解除されたリボンロール20が取り外される移動方向2Zとが一致する。故に、カセット1Bに支持されたインクリボン2は、より簡単な操作で取り外される。
