Ink jet printing head and electronic machine incorporating the same |
摘要 |
An ink jet printing head which is composed of a smaller number of parts than those in a conventional one, which leads to a reduction in the number of assembly steps, enhanced productivity and a reduction in the cost. A piezoelectric element is provided on a diaphragm at the portion corresponding to each pair of adjacent pressure chambers. A piezoelectric element includes an electrode which extends along each pressure chamber. An electronic machine incorporating this ink jet printing head is also provided.
