Abstract

PURPOSE:To improve a response frequency of ink jet by setting a connecting part, where ink flows, near the tip end of an injection passage. CONSTITUTION:Somewhat inside the nozzles 14, 15, 16 are set nozzles 18, 19 so that the nozzle 14 at the edge forms a connecting part 20 whose end 21 contacts the atmosphere. also, the part reaching the connecting part 17, 18, 19 is almost made straight, and the corner at the turning point to the connecting part 17, 18, 19 forms almost right angles. After the piezo of the nozzle 14 is driven to inject ink, the drawing is performed with ink being supplied from the connecting part 17, 20 at the same time when surface tension is applied to the corner part of the both sides of the connecting part 17, 20. Ink is returned due to the surface tension at the three points of nozzles 14, 15 and the connecting part 20. Since the returning is performed by the three points compared with the conventional one point method, the returning period is shortened to about one-third, improving the response frequency almost three times shorter than in a conventional method.
