Latest Patents
Soga holds a patent for a "Method and device for supplying ink to a print head." This invention features a main ink chamber with a through-hole that contains a capillary member. An intermediate ink chamber is strategically placed on the side wall of the main ink chamber. A path connects the main ink chamber and the intermediate ink chamber, ensuring efficient ink flow. The design includes a second meniscus forming member in a joint port to prevent ink leakage. During print mode, ink flows from the main ink chamber to the joint port through the meniscus forming member. Air bubbles that mix with the ink are directed along the slanting upper wall of the path by buoyant force, accumulating in the upper part of the intermediate ink chamber. When the ink level in the main ink chamber reaches zero, air bubbles are introduced into the intermediate ink chamber, quickly reducing the liquid level and indicating that the ink is used up.
