    • An ink supplying container is disclosed. In the ink supplying container, when the internal pressure of an ink container is made a positive pressure which is higher than atmospheric pressure so that nozzles of a recording head are cleaned and recovered by discharging a small amount of ink, a volume control unit restrains a flexible member of the ink container from expanding. When the internal pressure of the ink container is made a negative pressure optimal for printing which is lower than the atmospheric pressure so that a letter and/or an image is printed on a recording medium by the recording head, the volume control unit does not restrain the flexible member from expanding, and the volume of the ink container is maintained at almost the same volume as that at the time when the internal pressure of the ink container is made the positive pressure.
    • 公开了一种供墨容器。 在供墨容器中,当墨水容器的内部压力成为高于大气压力的正压时,通过排放少量的墨水来清洁和回收记录头的喷嘴,音量控制单元限制 墨水容器的柔性部件膨胀。 当墨水容器的内部压力被制成为低于大气压力的打印最佳的负压时,由记录头将字母和/或图像印在记录介质上,音量控制单元不会抑制 柔性构件膨胀,并且油墨容器的体积保持在与油墨容器的内部压力为正压时几乎相同的体积。
