摘要： An ink-dot printer comprises a recording paper, at least one needle disposed in one side the recording paper and movable between a rest position remote from the recording paper and a projected position close to the recording paper, a driving mechanism for moving the needle between the rest position and the projected position, a driving control unit electrically connected to the driving mechanism so as to supply a driving control signal for controlling the movement of the needle to the driving mechanism, an ink supply mechanism adapted to supply ink to the distal end portion of the needle on the recording sheet side so that the ink attaches to the distal end portion when the needle is located in the rest position, an electrode disposed in another side of the recording paper and facing the distal end portion of the needle, and voltage control unit for applying between the needle and the electrode an ink flying voltage with respect to the supply of the driving control signal from the driving control unit to the driving mechanism the ink flying voltage generating between the needle and the electrode an ink flying electric field of an intensity such that the ink is drawn from the distal end portion of the needle to the recording paper to form an ink dot on the recording paper as the needle closes to the electrode than in the rest position.
摘要翻译：一种墨点打印机包括记录纸，至少一个针设置在记录纸的一侧，并且可在远离记录纸的静止位置和靠近记录纸的突出位置之间移动;驱动机构，用于在针静止位置和突出位置，驱动控制单元，其电连接到驱动机构，以便提供用于控制针头到驱动机构的运动的驱动控制信号;墨水供应机构，适于向远端供应墨水针在记录纸侧的部分，使得当针位于静止位置时，油墨附着到远端部，设置在记录纸的另一侧并面向针的前端部的电极，以及电压控制单元，用于在针和电极之间施加相对于来自驱动器的驱动控制信号的供给的喷墨电压所述驱动机构在所述针和所述电极之间产生墨水飞溅电压，所述墨水飞溅电场的强度使得所述墨从所述针的远端部分被拉出到所述记录纸上以形成墨点作为针的记录纸比静止位置靠近电极。
