    • Ribbon tension detecting means (20, 21), which are formed of a plate-like lever body (35) each, are located individually on the upstream side and the downstream side of a platen (7) with respect to its travel. The plate-like lever body (35) has first and second rollers (47, 48) on the upstream and downstream sides with respect to travel of a ribbon, and swings around an axis of rotation of the second roller (48), depending on a tension of the ribbon traveling guided by the rollers (47, 48). If the amount of its swing is not less than or not more than a fixed value, a ribbon feed motor (18) or a ribbon take-up motor (19) is driven. Further, the ribbon tension detecting means (20, 21) are provided with a smoothing member which touches the ink ribbon (13) to remove wrinkles from the ink ribbon (13).

    • A simulation method includes the step of momently measuring a value of each of a strain, a strain speed, and a stress generated in the viscoelastic material, deriving time history data of a viscous drag, the strain speed and the stress, thereby deriving a relationship among the strain, the strain speed, and the viscous drag and setting the product as a product model whose performance is analyzed; inputting the relationship to the product model; and computing a stress and strain of a deviation component by using a deviation main strain and a deviation main strain speed converted from an entire coordinate system into a main strain coordinate system and a main strain speed coordinate system respectively to thereby conduct a simulation in consideration of a change of the viscous drag which occurs in dependence of a variation of the strain and the strain speed.
    • 模拟方法包括以下步骤:简单地测量在粘弹性材料中产生的应变,应变速度和应力中的每一个的值,导出粘滞阻力,应变速度和应力的时间历史数据,从而导出关系 在应变,应变速度和粘滞阻力之间,将产品设置为性能分析的产品模型; 输入与产品型号的关系; 以及通过使用从整个坐标系转换成主应变坐标系和主应变速度坐标系的偏差主应变和偏差主应变速度来分别计算偏差分量的应力和应变,从而进行考虑 根据应变和应变速度的变化而发生的粘性阻力的变化。
