发明名称 Method of controlling paper transportation in an apparatus, and an apparatus using the method
摘要 A paper transportation control method for an apparatus enables conveying paper with appropriate tension on the paper by appropriately controlling the paper delivery operation of a delivery roller. When paper is conveyed by the paper feed roller pair 34 of a roll paper printer 1, and the tension on the paper 8a is detected to exceed an upper tension limit based on the displacement of a damping mechanism 32 (time t2), the paper delivery operation of a delivery roller pair 33 starts at a time t3 after a start operation delay time DLS (first delay time) corresponding to the feed rate V(34) passes after time t2. When the tension returns to or below the upper tension limit, the paper delivery operation stops at a time t5 after a stop operation delay time DLE (second delay time) similarly corresponding to the feed rate V(34) passes. Tension fluctuation (change in the load on the paper feed roller) can be controlled without causing chattering or fluttering in paper delivery operation control.
