従来から、帯状のラベル連続体やタグなどの印刷用紙に各種の情報を印刷して表示するための印刷用紙用プリンターにおいて、一般的には印刷用紙をロール状に巻いてプリンター内の用紙供給部に装填し、この用紙供給部から移送路上を用紙印刷部に向かって帯状に繰り出すようにしている。　とくに、印刷用紙として、例えば各種機器の品番や特定情報を示すための銘板ラベルなどのラベル連続体を用いる場合には、帯状の台紙上にその複数枚を仮着しているラベル片（銘板ラベル）のサイズが比較的小さい場合が多く、移送されてゆくラベル連続体（ラベル片）と用紙印刷部との相対的位置を正確に設定可能として、とくに印刷位置精度を所定範囲内に確保する必要がある。　すなわち、用紙供給部における回転体としてのロール状印刷用紙のガタつき、あるいは移送路への操出し及び用紙印刷部における間欠的な印刷動作にともなう慣性による不安定な回転を減少させ、帯状の印刷用紙に所定の張力を付与し、移送路上の蛇行を防止するとともに、移送の安定性を確保し、用紙印刷部における印刷用紙上の印刷位置を正確に得ることができるようにすることが必要である。　 Conventionally, in a printer for printing paper for printing and displaying various types of information on printing paper such as a continuous strip of labels and tags, the paper supply unit in the printer is generally rolled up in a roll And is fed out from the paper supply unit to the paper printing unit in a strip shape. In particular, as a printing paper, for example, when using a label continuum such as a nameplate label for indicating the product number and specific information of various devices, a label piece (nameplate label) temporarily attached to a strip of backing paper. ) Is relatively small in size, and the relative position between the label continuum (label piece) being transferred and the paper printing section can be set accurately. There is. In other words, the roll-shaped printing paper as a rotating body in the paper supply unit rattles, or the unstable rotation due to inertia caused by the operation to the transfer path and the intermittent printing operation in the paper printing unit is reduced, and the belt-like printing It is necessary to apply a predetermined tension to the paper to prevent meandering on the transfer path, to ensure the stability of the transfer, and to accurately obtain the printing position on the printing paper in the paper printing section. is there. *

The first inclined surface 23c-1 is an inclined surface formed facing the roll supply shaft 25 in a state where the roll supply shaft 25 is mounted. The first inclined surface 23c-1 is in a state where it is in contact with the roll supply shaft 25 or in a state where it can be contacted in a state where the roll supply shaft 25 is mounted. The second inclined surface 23c-2 is an inclined surface facing outward without facing the roll supply shaft 25 side in a state where the roll supply shaft 25 is mounted. The second inclined surface 23c-2 temporarily contacts the roll supply shaft 25 in the process of mounting the roll supply shaft 25. *
バネ架け部２３ｄは、後述する付勢部材２４の一端が架けられる部分である。バネ架け部２３ｄは、軸３０と略平行な方向に軸保持部材２３の中央付近から突出して設けられている。　 The spring hanging portion 23d is a portion where one end of an urging member 24 described later is hung. The spring hanging portion 23 d is provided so as to protrude from the vicinity of the center of the shaft holding member 23 in a direction substantially parallel to the shaft 30. *
付勢部材２４は、ねじりコイルバネであり、コイル形状の部分が軸３０に架けられ、一方の腕部がバネ架け部２３ｄに架けられ、他方の腕部が上流側幅規制板１８に当て付けられている。したがって、付勢部材２４は、軸保持部材２３をロール供給軸２５の軸線に沿った方向において、ロール供給軸２５に近づく向きに付勢する。　この付勢部材２４の作用により、軸保持部材２３は、ロール供給軸２５への摩擦力を与えることができる。　すなわち、付勢部材２４は、軸保持部材２３の供給凹部２３ｂ及び斜面部２３ｃがロール供給軸２５に対して所定の付勢力で接触しており、ロール供給軸２５に印刷用紙５の移送路９への操出し動作に抵抗する負荷を付与可能である。　なお、本実施形態では、ロール供給軸２５よりも突出量が少なく、ロール供給軸２５よりも外径の大きな基部２５ａにも軸保持部材２３が接触している。これにより、ロール保持部材２２に与える負荷をより大きくしている。なお、基部２５ａに軸保持部材２３を接触させなくてもよい。　 The urging member 24 is a torsion coil spring, a coil-shaped portion is hung on the shaft 30, one arm portion is hung on the spring hanger 23d, and the other arm portion is abutted against the upstream side width regulating plate 18. ing. Therefore, the urging member 24 urges the shaft holding member 23 in a direction approaching the roll supply shaft 25 in a direction along the axis of the roll supply shaft 25. The shaft holding member 23 can apply a friction force to the roll supply shaft 25 by the action of the urging member 24. In other words, the biasing member 24 is such that the supply recess 23 b and the inclined surface portion 23 c of the shaft holding member 23 are in contact with the roll supply shaft 25 with a predetermined biasing force, and the transfer path 9 for the printing paper 5 to the roll supply shaft 25. It is possible to apply a load that resists the operation of moving to. In this embodiment, the shaft holding member 23 is also in contact with the base portion 25a that has a smaller protrusion than the roll supply shaft 25 and has a larger outer diameter than the roll supply shaft 25. Thereby, the load given to the roll holding member 22 is further increased. The shaft holding member 23 may not be in contact with the base portion 25a. *
図６に示すロール供給軸２５を装着した状態から、図７に示すロール供給軸２５を取り外した状態に移行するときには、ロール供給軸２５を着脱方向Ｙの方向にそのまま引き出す所定以上の力を加える。そうすると、ロール供給軸２５が第１斜面２３ｃ－１を押すことにより、軸保持部材２３は、付勢部材２４の付勢力に抗して軸保持部材２３によるロール供給軸２５の保持状態を解除する方向に力を作用させる。これにより、作業者は、単に、ロール供給軸２５（ロール保持部材２２）を着脱方向に所定以上の力で引っ張るだけで、ロール保持部材２２を取り外すことができる。　 When shifting from the state in which the roll supply shaft 25 shown in FIG. 6 is mounted to the state in which the roll supply shaft 25 shown in FIG. 7 is removed, a force greater than a predetermined force is applied to pull out the roll supply shaft 25 as it is in the attaching / detaching direction Y. . Then, when the roll supply shaft 25 pushes the first slope 23c-1, the shaft holding member 23 releases the holding state of the roll supply shaft 25 by the shaft holding member 23 against the urging force of the urging member 24. Apply force in the direction. Thereby, the operator can remove the roll holding member 22 simply by pulling the roll supply shaft 25 (roll holding member 22) in the attaching / detaching direction with a predetermined force or more. *
これとは逆に、図７に示すロール供給軸２５を取り外した状態から、図６に示すロール供給軸２５を装着した状態に移行するときには、第２斜面２３ｃ－２に向かってロール供給軸２５を着脱方向Ｙの方向に所定以上の力を加えて押し込む。そうすると、ロール供給軸２５が第２斜面２３ｃ－２を押すことにより、軸保持部材２３は、付勢部材２４の付勢力に抗して左右で対向する供給凹部２３ｂの間隔が開く方向に移動する。そのままロール供給軸２５を押し込むと、ロール供給軸２５が供給凹部２３ｂに嵌り、装着が完了する。このように、作業者は、単にロール供給軸２５（ロール保持部材２２）を着脱方向に所定以上の力で押し込むだけで、ロール保持部材２２を装着することができる。　 On the contrary, when the roll supply shaft 25 shown in FIG. 7 is removed and the roll supply shaft 25 shown in FIG. 6 is attached, the roll supply shaft 25 is directed toward the second inclined surface 23c-2. Is pushed in the direction of the attaching / detaching direction Y by applying a predetermined force or more. Then, when the roll supply shaft 25 pushes the second inclined surface 23c-2, the shaft holding member 23 moves in the direction in which the gap between the supply recesses 23b facing left and right is opened against the urging force of the urging member 24. . When the roll supply shaft 25 is pushed in as it is, the roll supply shaft 25 is fitted into the supply recess 23b, and the mounting is completed. Thus, the operator can mount the roll holding member 22 simply by pushing the roll supply shaft 25 (roll holding member 22) in the attaching / detaching direction with a predetermined force or more. *
したがって、軸保持部材２３及び付勢部材２４により印刷用紙５の繰出し方向Ｘには必要なブレーキ力を確保するとともに、軸保持部材２３における印刷用紙５（ロール供給軸２５）の着脱方向Ｙには、斜面部２３ｃの作用により、比較的弱い抵抗力でその着脱操作を容易にすることができる。　 Therefore, the shaft holding member 23 and the urging member 24 ensure a necessary braking force in the feeding direction X of the printing paper 5 and also in the attaching / detaching direction Y of the printing paper 5 (roll supply shaft 25) on the shaft holding member 23. By the action of the inclined surface portion 23c, the attaching / detaching operation can be facilitated with a relatively weak resistance force. *
ここで、開閉蓋４及び開閉ブラケット１０をプリンター本体２に対して開放した状態では、開閉ブラケット１０とプリンター本体２との間に装填開放口３６が形成されている。本実施形態の軸保持部材２３では、この装填開放口３６から着脱方向Ｙに沿って、斜面部２３ｃの第１斜面２３ｃ－１及び第２斜面２３ｃ－２が形成されている。よって、作業者にとってロール保持部材２２の着脱作業が行いやすくなっている。　 Here, when the opening / closing lid 4 and the opening / closing bracket 10 are opened with respect to the printer main body 2, a loading opening 36 is formed between the opening / closing bracket 10 and the printer main body 2. In the shaft holding member 23 of the present embodiment, the first inclined surface 23c-1 and the second inclined surface 23c-2 of the inclined surface portion 23c are formed from the loading opening 36 along the attaching / detaching direction Y. Therefore, it is easy for the operator to perform the attaching / detaching work of the roll holding member 22. *
こうした構成の印刷用紙用プリンター１及び印刷用紙５の供給軸装置２０において、開閉蓋４及び開閉ブラケット１０を開放した状態で、用紙供給部６における軸保持部材２３にロール保持部材２２を接触して保持可能である。　すなわち、左右一対の外面にそれぞれロール供給軸２５を突出させているロール保持部材２２に印刷用紙５をロール状に保持し、一対の軸保持部材２３によってロール供給軸２５を保持するとともに、付勢部材２４により軸保持部材２３をロール供給軸２５の軸線に沿った方向に付勢することにより、ロール供給軸２５に印刷用紙５の操出し動作に抵抗する負荷を付与しつつ、印刷用紙５を移送路９に帯状に繰り出すことができる。　用紙供給部６（供給軸装置２０）への印刷用紙５の着脱にあたっては、ロール保持部材２２のロール供給軸２５を装填開放口３６から軸保持部材２３に向かって斜め下方に押し込む操作、あるいは軸保持部材２３からロール供給軸２５を斜め上方に引き抜く操作だけでよく、その着脱操作がきわめて簡単である。　 In the printing paper printer 1 and the printing paper 5 supply shaft device 20 configured as described above, the roll holding member 22 is brought into contact with the shaft holding member 23 in the paper supply unit 6 with the opening / closing lid 4 and the opening / closing bracket 10 being opened. It can be held. That is, the printing paper 5 is held in a roll shape on the roll holding member 22 that protrudes the roll supply shaft 25 on the pair of left and right outer surfaces, and the roll supply shaft 25 is held by the pair of shaft holding members 23 and urged. By urging the shaft holding member 23 in the direction along the axis of the roll supply shaft 25 by the member 24, a load that resists the operation of driving the print paper 5 is applied to the roll supply shaft 25, and the printing paper 5 is loaded. It can be fed out to the transfer path 9 in a strip shape. When the printing paper 5 is attached to or detached from the paper supply unit 6 (supply shaft device 20), an operation of pushing the roll supply shaft 25 of the roll holding member 22 obliquely downward from the loading opening 36 toward the shaft holding member 23, or the shaft Only the operation of pulling the roll supply shaft 25 obliquely upward from the holding member 23 is required, and the attaching / detaching operation is extremely simple. *
なお、その幅が異なる印刷用紙５を装填する際には、左右一対の幅規制板（上流側幅規制板１８及び下流側幅規制板１９）を位置調節することになる。しかし、軸保持部材２３及び付勢部材２４は、上流側幅規制板１８に対して取り付けられており、上流側幅規制板１８の位置が変化しても、付勢部材２４が軸保持部材２３に対して与える付勢力に変化はない。よって、上流側幅規制板１８を位置調節しても、印刷用紙５の装填時における径方向及び軸方向のガタつきを、ともに吸収可能であり、印刷用紙５の安定した移送を実現可能である。　 When loading the printing paper 5 having different widths, the position of the pair of left and right width regulating plates (the upstream side width regulating plate 18 and the downstream side width regulating plate 19) is adjusted. However, the shaft holding member 23 and the urging member 24 are attached to the upstream side width regulating plate 18, and the urging member 24 does not move even if the position of the upstream side width regulating plate 18 changes. There is no change in the urging force given to. Therefore, even if the position of the upstream side width regulating plate 18 is adjusted, it is possible to absorb both the radial and axial backlash when the printing paper 5 is loaded, and it is possible to realize a stable transfer of the printing paper 5. . *
以上説明したように、本実施形態によれば、帯状に繰り出される印刷用紙５には、上流側のロール供給軸２５において摩擦による抵抗がかかり、所定レベルの張力が付与されつつ移送路９に移送される。したがって、用紙印刷部７のサーマルヘッド１３及びプラテンローラー１４に対する相対的位置精度を所定範囲内に維持することができ、印刷用紙５のサイズが小さな銘板ラベルのようなものであっても、移送機能を安定化し、印刷位置精度を良好にして印刷することができる。また、印刷用紙５の着脱操作も簡便である。　 As described above, according to the present embodiment, the printing paper 5 fed out in a strip shape is subjected to friction resistance at the upstream roll supply shaft 25 and is transferred to the transfer path 9 while being given a predetermined level of tension. Is done. Therefore, the relative positional accuracy of the paper printing unit 7 with respect to the thermal head 13 and the platen roller 14 can be maintained within a predetermined range, and even if the size of the printing paper 5 is a small nameplate label, the transfer function Can be printed with good printing position accuracy. Also, the operation for attaching and detaching the printing paper 5 is simple. *
