发明名称 LIQUID TANK AND LIQUID DISCHARGING RECORDER WHERE THE LIQUID TANK IS TO BE MOUNTED
摘要 PROBLEM TO BE SOLVED: To stably supply a lot of ink per unit time without decreasing the reliability of ink storage in an ink tank which has an ink storage chamber and an absorber chamber. SOLUTION: The ink tank 1 has the ink storage chamber 7 for directly holding the ink 6, and the absorber chamber 5 which stores absorbing members 4a and 4b for absorbing and holding the ink 6. Both chambers are divided by a partition 8, and a communication part 9 for making both chambers communicate with each other is formed in the partition 8. The ink storage chamber 7 is substantially sealed except the communication part 9. An ink supply port 3 and an atmosphere communication opening 2 are formed in the absorber chamber 5. An ink introduction passage 14 is formed by a groove which extends from the communication part 9 to a position separated by only a predetermined distance from the ink supply port 3 at a bottom face of the ink tank 1.
