プリンタ1は、発行口EJ側を上に向けた状態(横置き)で使用してもよいし、発行口EJ側を横に向けた状態(縦保持)で使用してもよい。プリンタ1を縦保持で使用する場合、プリンタ1の底面に設けられたベルトフック(図示せず)を作業者のベルトに引っかけてもよいし、プリンタ1に装着されたショルダーベルト(図示せず)を作業者の肩に掛けてもよい。
以下の説明において参照される断面図は、プリンタ1を平面に置いたときに、当該平面に直交し、かつ、前後方向に沿った平面でプリンタ1を切断したときの断面を示している。
本体ケース2の一面には、図3に示すように、開口2aが形成されている。
この開口2a内には、収容室6が設けられている。収容室6は、ロール紙Rを収容する空間である。
収容室6の内部には、用紙ガイド6aが設けられている。用紙ガイド6aは、ロール紙Rの両側面に接触した状態でロール紙Rを回転可能に支持することにより、収容室6から繰り出される連続紙Pの搬送をガイドするように構成される。用紙ガイド6aは、ロール紙Rの幅方向に沿って移動可能である。
台紙PMの裏面(第2面の一例)には、所定間隔毎に位置検出マークMが形成されている。位置検出マークMは、ラベルPLの基準位置を示すマークである。
ラベルPLの印字面の裏面は、粘着部である。粘着部は、粘着剤によって被覆されている。台紙PMのラベル貼付面にラベルPLの粘着部が貼り付くことにより、ラベルPLが台紙PMに仮着される。
センサ12aは、ラベルPLの基準位置(すなわち、台紙PMの位置検出マークM)を検出するセンサである。センサ12aは、例えば、反射型の光センサである。
センサ12bは、例えば、ラベルPLの有無(換言すると、台紙PMにおいてラベルPLが仮着されている部分と仮着されていない部分)を検出するセンサである。センサ12bは、例えば、透過型の光センサである。
剥離ユニット4の前後方向の一端は、プリンタ1の内部の連続発行位置(第2位置の一例)と、プリンタ1の外部の剥離発行位置との間を移動可能である。剥離ユニット4の詳細は後述する。
フロントカバー5は、表示部15と、操作ボタン16a,16bと、電源ボタン17と、カバー開放用ボタン18と、一対の解除レバー19と、カッタ20とを備えている。

本実施形態の剥離ユニットの構成について説明する。図5は、図2のプリンタの剥離ユニット、及び、その周囲の要部の拡大斜視図である。図6は、図5の剥離ユニットの要部の側面図である。図7は、図5の剥離ユニットの全体斜視図である。図8は、図7の剥離ユニットの分解斜視図である。
一対の台紙押さえ部8は、軸部4bの両端に設けられている。
剥離ローラ4aの長さは、軸部4bの全長よりも短い。剥離ローラ4aは、一対の台紙押さえ部8の間(つまり、軸部4bの略中央)に設けられている。剥離ローラ4aは、軸部4bにより回動自在に軸支されている。
剥離発行状態において、剥離ローラ4aは、プラテンローラ10に対してサーマルヘッド28から離間した側に位置する。剥離ローラ4aは、台紙PMを介して、プラテンローラ10側に押される。これにより、ラベルPLが剥離した台紙PMは、プラテンローラ10と剥離ローラ4aとによって挟持される。このとき、剥離ローラ4aは、プラテンローラ10に従動回転する。
台紙押さえ部8の後方端には、突起8dが形成されている。突起8dは、剥離ローラ4aより後方RRに突出している。
なお、図7~図8では、リブ8aの図示は省略している。
各支持部4cの上部には、庇部4cpが形成されている。庇部4cpは、各支持部4cの側面から外側に向かって延びている。
各支持部4cの前方(FR)には、図7に示すように、ガイドレール孔(長孔)4chが形成されている。ガイドレール孔(長孔)4chは、支持部4cの前後方向に沿って延在している。ガイドレール孔4chは、剥離ユニット4の前後方向の移動を案内し、かつ、規制する孔である。
なお、本実施形態では、一対の支持部4cに対応する一対のシャフト42を設ける例を示すが、シャフト42は、支持部4cと一体であってもよい。
揺動軸は、シャフト42に限られるものではない。揺動軸は、軸として作用する部材(例えば、突起など)であれば、どのようなものでもよい。
板バネ4daは、図6に示すように、支持部4cの外側側面において、支持部4cの後方RRに固定される。各板バネ4daは、支持部4cの後方RRから前方FRに向かって湾曲状に延在し、かつ、終端部で浮遊している。
本実施形態のプリンタの内部構造について説明する。図9は、剥離発行状態における図1のプリンタの断面図である。図10は、図9の要部拡大図である。図11は、ユニット押さえ部の作用を説明するための図9の要部拡大図である。
サーマルヘッド28のうち回路基板36と対向しない面(以下「印字面」という)は、開閉カバー3が閉鎖状態のときに、プラテンローラ10に対向し、かつ、台紙PM及びラベルPLの搬送経路を向いている。サーマルヘッド28の印字面には、複数の発熱抵抗体(発熱素子)が設けられている。複数の発熱抵抗体は、連続紙Pの幅方向に沿って並んでいる。各発熱抵抗体は、通電により発熱する。
本実施形態の支持台41について説明する。図12は、連続発行位置に設定された剥離ユニットと支持台とを示す斜視図である。図13は、図12の剥離ユニット及び支持台の側面図である。図14は、図13の剥離ユニット及び支持台の関係の説明図である。
各リブ8aは、台紙押さえ部8の前方端から前方(FR)及び下方に突出している。
第1の取付片41baは、台座部41aの幅方向(つまり、プリンタ1の横方向)において外側に位置する。
第2の取付片41bbは、台座部41aの幅方向において内側に位置し、かつ、第1の取付片41baに対向する。
第1の取付片41baと第2の取付片41bbとの間の横方向の間隙には、支持部4cが挟み込まれている。
また、コイルバネ44は、ガイドレール孔4chの前方端を支点にして、剥離ユニット4の前方端がサーマルヘッド28から離間する方向(以下、「第1回転方向」という)の付勢力を剥離ユニット4に与える。
つまり、コイルバネ44は、剥離ユニット4に対して、後方RRにスライドさせる付勢力と、第1回転方向に揺動させる付勢力とを与える。
第1の爪部4cjは、ガイドレール孔4chの上方に設けられている。
第2の爪部4ckは、ガイドレール孔4chの下方に設けられている。
第1の突出部41be及び第2の突出部41bfは、第1の取付片41baにおける第2の取付片41bbとの対向面に設けられている。
ガイド面45は、剥離ユニット4を前後方向に案内する面である。剥離ユニット4が前後方向にスライドしている間、第1の爪部4cjはガイド面45に摺動する。これにより、剥離ユニット4が前後方向に案内される。
第1のストッパ46は、剥離ユニット4の揺動端位置(第2位置の一例)を規定する部材である。揺動した剥離ユニット4は、第1の爪部4cjが第1のストッパ46に当接する揺動端位置で停止する。
規制面47は、剥離ユニット4が連続発行位置に戻ることを規制する面である。剥離ユニット4が第1回転方向とは反対の第2回転方向に揺動する(つまり、剥離ローラ4aがサーマルヘッド28に近接する方向に移動する)と、第1の爪部4cjは規制面47に摺動する。これにより、剥離ユニット4が連続発行位置に戻ることが規制される。
本実施形態の連続発行位置及び剥離発行位置について説明する。
本実施形態の連続発行位置と剥離発行位置との間の移動について説明する。図15~図20は、それぞれ、図5の剥離ユニットを剥離発行位置に設定する際の剥離ユニット及び開閉カバーの状態を示したプリンタの要部断面図である。
第1回転方向に揺動した剥離ユニット4は、揺動端位置で停止する。揺動端位置で停止した剥離ユニット4の前方端は、開閉カバー3の揺動軌跡内にある。
剥離ユニット4が揺動端位置にある場合、発行口EJが開放される。これにより、ロール紙Rを容易に装填することができる。
本実施形態の台紙押さえ部の作用について説明する。図21~図23は、図6の台紙押さえ部の作用の説明図である。
台紙PMは発行口EJ1の方向に押し出されているので、剥離ピン11に巻き付く。剥離ピン11は、剥離発行状態において、第1搬送位置P1と第2搬送位置P2との間で、台紙PMの搬送経路とラベルPLの搬送経路とを分岐させる。つまり、剥離ローラ4aが剥離発行位置にあるときに、ラベルPLが台紙PMから剥離可能である。このとき、剥離ピン11は、第1搬送位置P1と第2搬送位置P2との間で台紙PMの裏面を支持する。これにより、第1搬送位置P1と第2搬送位置P2との間における台紙PMの弛みを防止することができる。
このように、台紙押さえ部8は、第1搬送位置P1と第2搬送位置P2との間における台紙PMの弛みを防止する弛み防止機構として機能する。
本実施形態の連続発行状態及び剥離発行状態について説明する。図24は、本実施形態の連続発行状態で動作するプリンタの断面図である。図25は、本実施形態の剥離発行状態で動作するプリンタの断面図である。図26は、本実施形態の押さえ部が設けられていない場合の剥離ローラの近傍の拡大図である。図27は、本実施形態の剥離発行状態における剥離ローラの近傍の拡大図である。
一方、印字が行われたラベルPLの搬送経路は、剥離ピン11の位置で、台紙PMの搬送経路と分岐する。こにより、印字が行われたラベルPLは、剥離ピン11の位置で、1枚毎に台紙PMから剥離される。つまり、剥離発行状態では、ラベルPLが1枚毎に発行される。したがって、剥離発行状態は、対象物がプリンタ1の近くにある場合に特に適している。
また、剥離ローラ4aは、剥離発行位置にあるときに、台紙PMの搬送経路上の第2搬送位置P2において、プラテンローラ10に対向し、かつ、台紙PMに当接しながらプラテンローラ10に従動回転するように構成される。
換言すると、剥離ローラ4aは、剥離発行位置にあるときに、台紙PMの搬送経路のうち、剥離ピン11が台紙PMの裏面(図27において、台紙PMの下方の面)に当接する位置と台紙PMの発行口EJ1(図27において、サーマルヘッド28とプラテンローラ10とが対向する第1搬送位置P1を基準として後方RRに設けられた発行口EJ1)との間で、台紙PMの表面(図27において、台紙PMの上方の面)に当接しながらプラテンローラ10に従動回転する。
本実施形態の変形例について説明する。
本実施形態の変形例1について説明する。変形例1では、台紙押さえ部の形状の変形例について説明する。
図28は、変形例1の連続発行位置に設定された剥離ユニットと支持台とを示す斜視図である。図29は、変形例1の剥離ローラの第1例の近傍の拡大図である。図30は、変形例1の剥離ローラの第2例の近傍の拡大図である。
この場合、図20に示すように剥離ユニット4が剥離発行位置に設定されると、第2リブは、図22のリブ8aと同様に、弛んだ台紙PMに接触し、かつ、プラテンローラ10と台紙PMとの間隔が狭まるように、台紙PMを下方に押さえる。
本実施形態の変形例2について説明する。変形例2では、プラテンローラ10及び剥離ピン11の前方の空間(つまり、第1搬送位置P1と剥離ピン11との間)における台紙の弛みを防止する例について説明する。
図31は、変形例2のスペーサの作用を説明するための図9の要部拡大図である。
図27では、台紙PMから剥離されたラベルPLの搬送方向(第2の方向D2)が上方向である例について説明したが、第2の方向D2はこれに限られない。
第2の方向D2は、第1の方向D1を基準として、剥離ローラ4aから離間する方向(つまり、プリンタ1の前方FRへ傾斜する方向)であれば、どのような方向でもよい。
