摘要： The size of patterns printed by an ink jet system printer including an ink liquid issuing nozzle, a charging electrode and deflection electrodes is temperature dependent. When the ink liquid temperature increases, viscosity of the ink liquid reduces and hence a flow rate of the ink liquid increases. This causes both mass and a flying rate of an ink droplet emitted from the nozzle to increase. Therefore, a deflection amount becomes smaller and hence the printed pattern size becomes smaller than that of ordinary desired. A temperature senser is provided on an ink conduit adjacent to the nozzle, for detecting the ink liquid temperature and generating detecting signals. A voltage level of video signals applied to the charging electrode or a voltage level applied to the deflection electrodes is varied in accordance with the detecting signals in order to stabilize the size of the printed pattern. When the ink liquid temperature increases, the voltage level of the video signals applied to the charging electrode or the voltage level applied to the deflection electrodes is compensatively increased.
摘要翻译： 由包括油墨发出喷嘴，充电电极和偏转电极的喷墨系统打印机印刷的图案的尺寸是温度依赖性的。 当油墨液体温度升高时，油墨液体的粘度降低，因此油墨液体的流量增加。 这导致质量和从喷嘴发射的墨滴的飞行速率增加。 因此，偏转量变小，印刷图案尺寸变得比普通要求的尺寸小。 温度传感器设置在与喷嘴相邻的墨水导管上，用于检测墨液温度并产生检测信号。 根据检测信号，施加到充电电极的视频信号的电压电平或施加到偏转电极的电压电平是变化的，以便稳定印刷图案的尺寸。 当墨液温度升高时，施加到充电电极的视频信号的电压电平或施加到偏转电极的电压电平被补偿地增加。

摘要： In an ink jet system printer wherein ink droplets are emitted from a nozzle toward a recording paper, objectionable ink dust is formed and diffused in various directions after the ink droplets impinge upon the recording paper. When the diffused ink dust attaches to a unit such as deflection means, the system may operate erroneously. An electrode is arranged in a position suited for minimizing the deleterious effects of diffused ink dust from the ink jet system printer by the use of an electrostatic attraction force or an electrostatic repulsion force.

摘要： A pair of deflection electrodes at least one of which is grooved are provided to confront with each other in an ink jet system printer in order to deflect charged ink droplets emitted from a nozzle as they pass through a high voltage electric field established therebetween. Objectionable ink mist, which is unavoidably formed and diffused in various directions after the ink droplets impinge upon a recording paper or a beam gutter, attached to the grooved deflection electrode gathers and forms an ink drop, which is collected in an indent formed in the grooved deflection electrode. This precludes erroneous breaking down of the system and ensures stability of the high voltage electric field established between the pair of deflection electrodes.

摘要： A plate shaped slim electrode is mounted on a carriage which supports an ink issuing unit and a charging tunnel, and is driven to travel in the lateral direction. A cylinder shaped rotary deflection electrode is rotatably mounted on the body of an ink jet system printer in a direction parallel to the travelling direction of the carriage. In a preferred form, a slit opening is formed in the center of the plate shaped slim electrode. The plate shaped slim electrode is maintained at the ground potential, whereas the rotary deflection electrode is connected to a high voltage source to establish a high voltage electric field between the plate shaped slim electrode and the rotary deflection electrode.
