摘要： An ink tank includes a detector element that optically detects a condition of ink. The ink tank includes a first ink chamber adapted to be opened to an external environment. A second ink chamber communicates with the first ink chamber and includes a bottom surface with protrusions. A third ink chamber is disposed below the second ink chamber relative to a direction of gravity. The ink tank also includes an ink passage by which the second ink chamber communicates with the third ink chamber. An ink outlet communicates with the third ink chamber. The detector element is arranged so as to face at least one of the ink passage and the third ink chamber.

摘要： An ink tank of the foam type which is provided with a detected portion capable of exactly and surely detecting the amount of ink used by the printer or remaining in the ink tank. The ink tank includes a sub ink chamber that is diposed or formed between a main ink chamber and an ink outlet of an ink tank of a foam type. When an amount of air flowing into the sub ink chamber increases, one or more reflecting surfaces of a right-angled prism, which function as ink interfaces, resume their original function of reflecting surfaces, thereby enabling the detection of an ink end. Air bubbles having entered the sub ink chamber are surely led onto the one or more reflecting surfaces by a bubble storage part. At an ink passage having a narrow width, which is defined by the one or more reflecting surfaces, air bubbles are pressed against the one or more reflecting surfaces to be put to a crushed state and in surface contact with the latter. Air bubbles are surely led onto the one or more reflecting surfaces, and are crushed and pressed against the reflecting surfaces. This configuration prevents the one or more reflecting surfaces from being covered with ink retained in spaces among the air bubbles. Therefore, the ink end can be detected surely and exactly.

摘要： An ink cartridge 2 with a waste ink absorbing function includes a division room 70 formed in the interior portion of a cartridge case 30 for storing a waste ink absorbing member 20, and a plastic film 60 forming at least part of the division room 70. By cutting or peeling off the plastic film 60, the waste ink absorbing member 20 stored within can be replaced, which simplifies the replacement of the waste ink absorbing member 20. After replacement, the plastic film 60 may be mounted onto the cartridge case 30. Use of the plastic film is economical when compared with a structure in which a plastic plate is mounted onto a cartridge case. Also, the ink cartridge 2 can be reduced in size and weight as a whole.
