Abstract

PURPOSE:To prevent the leakage of ink from a vent hole, by arranging an ink absorber in close vicinity to the outside opening part of the air venting means for communicating the liquid chamber of an ink container with the open air. CONSTITUTION:A recording head 3 and an ink container 4 are mounted on the carriage 2 moving left and right along platen rolls 1, 1. The interior of the ink container 4 is partitioned into a lower liquid chamber 11 and an upper open air communication chamber 12, ink is accumulated in the liquid chamber 11 while an ink absorber 13 is arranged in the open air communication chamber 12. Therefore, even if ink is leaked or exued through an air venting needle 10 by the thermal expansion of air in the liquid chamber 11 or the inclination or vibration of the ink container 4, said ink can be absorbed by the ink absorber 13.

This inkjet recording device guides ink in an ink container to a recording head, and ejects the ink toward a recording material (paper) by driving multiple nozzles provided in the recording head according to a print pattern signal. It is configured. The ink container is generally detachably mounted and replaced with a new container after use. Further, the ink container is provided with an ink outlet for supplying ink to the recording head as well as a vent for maintaining the inside at atmospheric pressure. As a method of providing this ink outlet and vent,
For example, the ink supply needle connected to the recording head and the ventilation needle that communicates with the atmosphere are fixed in the container mounting section, and in conjunction with the container mounting operation, these needles are inserted into the mouth of the container to take out the ink. Methods of forming ports and vents have been proposed.
