Ink jet recording apparatus |
| 摘要 |
Grooves 21 are formed in the side of an ink supply needle 17 opposite a filter 19 in order to induce the movement of ink using capillary attraction, and so that the grooves 21 ensure that ink can flow along a path to a recording head regardless of whether an air bubble is present.
