BUBBLE JET PRINTING DEVICE, PRODUCTION OF SAID DEVICE, AND BUBBLE JET PRINTING HEAD

摘要

PURPOSE: To facilitate the accurate alignment between two parts in a two-part structure by forming an ink supply passage, a nozzle and a heater means integrally. CONSTITUTION: The passages 113, 114 piercing through the opposed surfaces of a semiconductor substrate 130 are formed by using semiconductor manufacturing technique and a part of them is formed into a nozzle for emitting an ink droplet 108 and an integrated BJ printing device having heater means 120 corresponding to the nozzle is constituted. Since this device is an one-part structure, there is no problem in the case of a two-part structure and the device is made long to easily provide a machinery corresponding to the whole width of recording paper.
