Ink supply device for use in ink jet printer and ink tank for use in the same device |
摘要 |
An ink supply device includes an ink container connected to an air communication port through a porous member. The ink container is maintained at a negative pressure equivalent to the capillary force of the ink penetrated into the porous member. Since the ink container is in communication with the air through a wide area of the porous member, the ink container can be maintained at a constant negative pressure regardless of the quantity of ink consumed by the recording head.
