Abstract
Description
前記収容部内に設けられ、ロール体の両側面に当接する一対の当接面を有し、ロール体をガイドするガイド部と、
前記当接面から内側方向に突出する第1位置と、前記当接面から内側方向に突出しない第2位置との間で移動可能であって、第2位置から第1位置に向けて付勢されており、第1位置においてロール体を回転可能に保持する保持部と、
前記保持部の動きに連動して変位する変位部と、
を備え、
前記変位部の少なくとも一部は、前記保持部が第1位置にある場合と第2位置にある場合とで異なる位置に変位していることが判別可能となるように、前記開口から見て露出している、
プリンタである。
以下、実施形態に係るプリンタについて、図1および図2を参照して説明する。
図1は、実施形態に係るプリンタ1について、開閉部3が開放状態である場合を示す斜視図である。図2は、実施形態に係るプリンタ1について、開閉部3が閉鎖状態である場合を示す斜視図である。
図1において、プリンタ1の底面は略長方形をなしており、その長辺に沿った方向を前後方向と定義する。すなわち、搬送方向下流側のプラテンローラ5が設けられている側を前方(FR)と定義し、その反対側の搬送方向上流側を後方(RR)と定義する。当該前後方向を基準として、右側(RH)、左側(LH)、上側(UP)および下側(LO)を定義する。なお、以下の説明では適宜、右側(RH)の方向または左側(LH)の方向を横方向といい、上側(UP)の方向または下側(LO)の方向を上下方向という。
以下の説明においてロール紙Rの「挿入方向」とは、例えば、下向き、又は、下向きよりも少し後方に傾斜した斜め下の方向である。
本実施形態のプリンタ1では、プラテンローラ5の回転によってロール紙Rから連続紙Pが繰り出されるが、収容部8には、連続紙Pが繰り出された後にプラテンローラ5に至るまでの搬送経路を形成する空間も含まれる。
開閉部3が閉鎖されて印字が行われているときには、ロール紙Rから繰り出される連続紙Pがプラテンローラ5によって搬送されつつ、プラテンローラ5とサーマルヘッド6の間で挟持される。このとき、サーマルヘッド6は、上記付勢力によってプラテンローラ5に押し付けられ、それによって印字に適したヘッド圧が生成される。
次に、ロール体保持機構10の構成について、図3~8を参照して説明する。
図3は、本実施形態に係るロール体保持機構10の斜視図である。
図4Aは、実施形態に係るロール体保持機構10に含まれる移動機構20のハウジングとロック部材の係合が維持されている状態を示す平面図である。図4Bは、実施形態に係るロール体保持機構10に含まれる移動機構20のハウジングとロック部材の係合が解除されている状態を示す平面図である。
図5は、本実施形態に係るロール体保持機構10のロール保持ユニットの分解斜視図である。図6は、本実施形態に係るロール体保持機構10のガイド部の部分斜視図である。図7は、本実施形態に係るロール体保持機構10の一部を一方の側面から側面図である。図8は、本実施形態に係るロール体保持機構10の一部を他方の側面から側面図である。
ガイド部12L,12Rは、プリンタ1の前後方向に延びた板状の部材であり、ロール紙Rの側面Rsに当接する当接面12s(図7参照)を有し、ロール紙Rの幅方向の移動を規制する。ロール保持ユニット14L,14Rは、ガイド部12L,12Rに対する相対位置を変更可能に設けられている。
移動機構20は、ハウジング21内に一対のラック22L,22Rおよびピニオン24を有する。ガイド部12Lとラック22Lは、一体で横方向に移動可能となるようにハウジング21の背面から締結部材220Lによって連結されている。ガイド部12Rとラック22Rは、一体で横方向に移動可能となるようにハウジング21の背面から締結部材220Rによって連結されている。
なお、図3は、ガイド部12L,12Rの横方向の移動が制限されていない状態を示している。
ガイド部12L,12Rを所望の位置に設定した後に操作部161に対する操作を停止した場合、コイルばね18の付勢力によって再びロック部材16の係合部163とハウジング21の係合部211が係合し、ガイド部12Lの横方向の移動が制限される。
ロール保持ユニット14L,14Rは、それぞれロール紙Rを保持する保持部1432L,1432Rを備えているが、以下の説明において共通して言及するときには、適宜、単に保持部1432という。
揺動部材143は、一方の端に設けられる筒状部1431(2箇所)と、他方の端に設けられる保持部1432と、筒状部1431と保持部1432を連結する胴部1433とを有し、揺動軸143Cの回りを揺動する。保持部1432は、揺動部材143の揺動に伴ってガイド部12Rの当接面12sから内側方向に突出する突出位置と当接面12sから内側方向に突出しない非突出位置の間で揺動可能に設けられ、突出位置でロール紙Rを回転可能に保持する。
突出位置および非突出位置は、それぞれ第1位置および第2位置の例である。
変位部145は、揺動部材143の揺動に連動して変位する。変位部145は、揺動部材143の揺動による保持部1432の位置の変化が収容部8の開口8bを通してユーザが確認できるようにするために設けられている。
揺動部材143は、捩りばね144に付勢された状態で、その胴部1433がストッパ1410Cに当接している。胴部1433がストッパ1410Cに当接した状態では、揺動部材143の保持部1432が板状本体部141の開口1410Aから、ガイド部12Lのロール紙Rに対する当接面12sよりも内側に突出した突出位置となっている。ロール紙Rを収容部8に挿入してロール体保持機構10に保持させるときには、ロール紙Rの外周面および側面Rsが保持部1432に当接し、それによって保持部1432が捩りばね144の付勢力に抗して図5の回転方向d2の向きに揺動する。その結果、保持部1432は、当接面12sよりも内側に突出しない非突出位置まで揺動する。
ロール保持ユニット14Rとガイド部12Rの取付態様については後述する。
図6を参照すると、ガイド部12Rには、矩形形状のロール保持ユニット14Rを受け入れるために実質的に矩形形状の開口120が形成されている。開口120の周縁部には、ロール保持ユニット14Rの取付部1412,1414を取り付けるために他の部分よりも薄肉の薄肉部122,124が形成されている。
開口120の周縁部には、内側に向けて突出する第1凸部126(2箇所)および第2凸部127(2箇所)が形成されている。
ガイド部12Rの頂部には、U字状の溝で構成された係合部125が形成されている。係合部125は、保持部1432が突出位置である場合に変位部145の端部1452と係合する。
ガイド部12Rにロール保持ユニット14Rが取り付けられた状態では、ロール保持ユニット14Rの取付爪1412Bが薄肉部124の一方の面に係合し、ロール保持ユニット14Rの取付爪1412C(2箇所)が薄肉部124の他方の面に係合する。ロール保持ユニット14Rの取付爪1414Bが薄肉部122の一方の面に係合し、ロール保持ユニット14Rの取付爪1414C(2箇所)が薄肉部122の他方の面に係合する。つまり、取付爪1412B,1412Cが薄肉部124をその両側から挟持し、取付爪1414B,1414Cが薄肉部122をその両側から挟持する構成になっている。
なお、可撓腕部1412A,1414Aが撓むことで各爪が薄肉部122,124から離脱可能であるため、ロール保持ユニット14L,14Rは、それぞれガイド部12L,12Rに対して着脱可能となっている。
次に、図9および10を参照してロール体保持機構10の動作について説明する。
図9Aはロール紙Rがロール体保持機構10に保持されていない場合のロール体保持機構10の概略正面図を示し、図9Bはロール紙Rがロール体保持機構10に保持されている場合のロール体保持機構10の概略正面図を示す。図10Aはロール紙Rがロール体保持機構10に保持されていない場合の変位部145の端部1452の位置を示し、図10Bはロール紙Rがロール体保持機構10に保持されている場合の変位部145の端部1452の位置を示す。
上述した実施形態では、ガイド部12Rの基準面に対する端部1452Rの相対的な位置関係が認識できるようにするための変位部145の構成の一例を示したが、その限りではない。
例えば図11Aに示す変形例では、以下のように変位部の端部1452Aが設定される。すなわち、保持部1432が突出位置にあるときに端部1452Aがガイド部12Aの裏面12Awと接触し、若しくは裏面12Awに最も近付く。保持部1432が非突出位置にあるときに端部1452Aがガイド部12Aの裏面12Awと接触しないか、若しくは裏面12Awから最も遠ざかる。
例えば図11Bに示す変形例では、保持部1432が突出位置にあるときに端部1452Bがガイド部12Bの係合部12Bvと係合し、保持部1432が非突出位置にあるときに端部1452Bがガイド部12Bの係合部12Bvと係合しないように、変位部の端部1452Bが設定される。
