リンタ用紙送り機構に関づる。DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a paper set for a printer, and more particularly to a printer paper feeding mechanism suitable for a cash register (ECR) or a point of sale (PO5).
従来の受取証（レシート）を発行する形式のプリンタ用
紙送り機構は、−取引毎に用紙を切断させる必要があり
、第１図のごとくロール紙１をローラ２で送りながら印
字ヘッド５、プラテン４の部分で印字し、その後カッタ
５部分で切断される構造になっていたので、用紙の先端
が前記機構の一部分にでも当り、そこで用紙が止まった
場合、ローラ２により新しい用紙が送り出されて来るた
めに、用紙送り機構の内部で用紙が目づまりを起こしや
すい欠点があった。Conventional printer paper feeding mechanisms that issue receipts require the paper to be cut for each transaction. Since the paper was designed to be printed in one section and then cut by the cutter 5, if the leading edge of the paper hit a part of the mechanism and the paper stopped there, a new paper would be sent out by the roller 2. Another drawback is that paper tends to become clogged inside the paper feed mechanism.
本発明の目的は、用紙の初期設定時の操作性を損うこと
なく、用紙の目づまりの起きＫくいプリンタ用紙送り機
構を提供することにある。SUMMARY OF THE INVENTION An object of the present invention is to provide a printer paper feeding mechanism that is less likely to cause clogging of paper without impairing operability during initial paper setting.

せるスイッチを設けたことを特徴とするものである。The present invention provides a printer comprising a mechanism for printing on roll paper and a mechanism for cutting the printed recording paper for each transaction, including a main roller for paper feeding, a sub-roller for initializing the paper, and the main roller. This is characterized by the provision of a switch that causes the sub rollers to operate in opposite phases.
以下、本発明の一実施例を第２〜第４図により説明する
。An embodiment of the present invention will be described below with reference to FIGS. 2 to 4.
第２図は用紙の初期設定時の準備段階としてロール紙を
用紙送りの端に準備した状態であり第３図は初期設定中
で用紙を自動送りしており第４図は、通常使用状態を表
わしている。Figure 2 shows a state in which roll paper is prepared at the end of the paper feed as a preparation stage for initial paper settings, Figure 3 shows paper being automatically fed during initial settings, and Figure 4 shows normal usage. ing.
用紙の初期設定時の準備段階として、第２図のごとくロ

ぐ。As a preparation step for initial setting of paper, the leading end 1' of the roll paper 1 is prepared inside the paper feeding sub roller 2-1 as shown in FIG. In the preparation stage, the operation changeover switches 6 for the sub roller 2-1 and the main roller 2-2 are turned off, so that the sub roller 2-1 is released and the main roller 22-2 is not released.
上記準備が完了後、スイッチ６をオンすることにより、
第５図のごとく副ローラ２−１が非解放、主ローラ２−
２が解放となり、副ローラ２−１でロール紙１は送り出
され、先端１′は印字ヘッド３とプラテン４０間を通り
、解放状態。After the above preparations are completed, by turning on switch 6,
As shown in Fig. 5, the sub roller 2-1 is not released, and the main roller 2-1 is not released.
2 is released, the roll paper 1 is sent out by the sub roller 2-1, the leading edge 1' passes between the print head 3 and the platen 40, and is in the released state.
の主ロー２２−２を全く抵抗を受けずに通り抜け、最後
にカッタ部５を過ぎたところでスイッチ６をオフとする
と同時に、用紙の自動送りを中止させる。The paper passes through the main row 22-2 of the paper without any resistance, and finally, when it passes the cutter section 5, the switch 6 is turned off, and at the same time, the automatic feeding of the paper is stopped.
第４図は、用紙の初期設定を完了した後の状態で、通常
使用時である。本状態では、副ロー２２−１は解放、主
ローラ２−２が非解放となっており、用紙送りは主ロー
２２−２により用紙送り機構内を引張る構造となってい
る。FIG. 4 shows the state after the initial setting of the paper is completed and is in normal use. In this state, the auxiliary roller 22-1 is released, the main roller 2-2 is not released, and the paper is fed by pulling the inside of the paper feeding mechanism by the main roller 22-2.
本実施例によれば、用紙の初期設定は簡゛単な操作によ
る自動送りが出来、又通常使用時は引張る構造のため、
途中で用紙が少々引掛っても強制的に引張られて、目づ
まりを起こしずらくなると云う効果がある。According to this embodiment, the initial setting of paper can be automatically fed with a simple operation, and the structure is such that it is pulled during normal use.
Even if the paper gets caught in the middle, it will be forcibly pulled, making it less likely to become clogged.
本発明によれば、用紙の初期設定時には、簡単に自動設
定ができるので、操作性は良好であり、又通常使用時は
用紙送り機構の出口で用紙を引張りだす方式となってい
るため、用紙の目づまりを防ぐ効果がある。According to the present invention, it is easy to automatically set the paper at the time of initial setting, so the operability is good.Also, during normal use, the paper is pulled out at the exit of the paper feed mechanism, so the paper can be easily set automatically. It has the effect of preventing clogging.
