    • PURPOSE: An ink tank, a cartridge equipping the ink tank and a printer using the cartridge are provided to detect liquid existence even when using a sort of ink dispersing a coloring agent. CONSTITUTION: An ink tank(7) has an air hole(120) inletting air and a receiving chamber(340) containing an absorber(320) as a material generating floating pressure. The receiving chamber and a liquid storage(360) are connected each other through only a channel(400) of a partition(380) formed near the lower ink tank. Many ribs(420) protruded to the ink tank are formed on an upper wall(7U) of the tank, and an air buffer chamber(440) is formed between the upper face of the absorber and the upper wall. The absorber keeps regular amount of floating pressure to a print head since air is supplied as the absorber even when ink is consumed by the printing head. After all ink is consumed by the absorber, ink of the liquid storage is supplied. Therefore, the liquid storage equips a prism of an ink detector informing a user of the replacement time of ink.
    • 目的:提供墨水盒,装有墨水盒的墨盒和使用墨盒的打印机,以便即使使用一种分散着色剂的墨水也可以检测液体存在。 构成:墨水罐(7)具有空气孔(120)和空气孔,容纳室(340)包含作为产生浮动压力的材料的吸收器(320)。 接收室和液体储存器(360)仅通过形成在下部墨水罐附近的分隔件(380)的通道(400)彼此连接。 在罐的上壁(7U)上形成有突出到墨罐的许多肋(420),并且在吸收体的上表面和上壁之间形成空气缓冲室(440)。 吸收器保持规定量的浮动压力到打印头,因为即使当墨水被打印头消耗时,空气也作为吸收剂供应。 在吸收器消耗所有油墨之后,供应液体储存器的油墨。 因此,液体储存装置将墨水检测器的棱镜通知用户墨水的更换时间。
