打印机的送纸控制方法及打印机
摘要：
一种通过适当控制抽出辊的抽纸动作，从而能够以适当的张力状态输送纸的打印机的送纸控制方法。在卷纸打印机(1)利用送纸辊对(34)进行送纸时，若根据缓冲机构(32)的变位检测到作用于纸(8a)的张力超过了上限值(时点t2)，则在从该时点经过了与进给速度(V(34))对应的动作开始延迟时间(DLS)(第一延迟时间)后的时点(t3)，开始由抽出辊对(33)进行的抽出动作，若张力回到上限值以下，则在同样经过了与进给速度(V(34))对应的动作停止延迟时间(DLE)(第二延迟时间)后的时点(t5)，停止抽出动作。在抽出动作控制中，能够不产生振动和波动地控制张力变动(作用于送纸辊对的负载变动)。
摘要（英）：

The invention provides a paper feeding control method of a printer, which can feed paper with proper tension state though properly controlling paper drawing action of a drawing roller. When a curl-paper printer (1) feeds paper through a paper feeding roller paper (34), if tension applied to paper (8a) is detected to be over an upper value (the time point is t2) according to position change of a buffering mechanism (32), the drawing roller pair (33) begins to draw at a time point (t3) after action starting delay time (DLS) (the first delay time) corresponding to the feeding speed (V(34)) from the time point t2; if the tension is below the upper value, drawing action is stopped at a time point (t5) after action stopping delay time (DLE) (the second delay time) corresponding to the feeding speed (V(34)). In drawing action control process, the tension changed (loading changed applied to the paper feeding roller) can be controlled without generating vibration and fluctuation.
