Abstract

PURPOSE:To arrange so that ink inside a tank may be completely used by arranging plural ink-impregnated members having varying capillary capacity in such a way that the capillary capacity gradually increases to the nearest member to the ink supply port. CONSTITUTION:When the ink is consumed completely, the ink in a porous member 62 flows into a printer head body through an ink guide groove 12b of an ink supply guide arm and a thin groove 45 of a tank bottom stepped part 44. At that time, the moving quantity of the ink in the porous member is negligible and therefore, almost no ink blocking occurs, because the ink movement is in the thickness direction of a plate-like porous member 62. Furthermore, if the ink is exhausted, a differential in the internal pressures of a porous member 61 and the porous member 62 generates immediately due to the difference of an average nozzle diameter. Thus the uninterrupted ink supply equivalent to an ink consumption from the porous member 61 to the porous member 62 results.

This structure uses the appropriate capillary force of the ink-impregnating member to supply an appropriate amount of ink to the printer head, and also prevents unintentional ink from flowing out from the tank's air port or ink supply hole. Holding everything can be easily realized.

用できないまま残ることになる。When using ink from an ink tank with such a structure, the capillary force within the ink-impregnated member near the ink supply port located far from the ink supply port of the ink tank increases as the ink is consumed, and the resulting ink This is the pressure difference between the ink and the ink located far from the supply port. However, as is noticeable with porous materials, ink-impregnated members generally experience a state in which the amount of ink impregnated decreases, fluid resistance increases, and the ink path becomes disrupted at various locations, making it difficult for ink to flow. become. Therefore, if the ink becomes difficult to flow before a pressure difference sufficient to move the ink is generated, the ink in the area far from the ink supply port remains unusable.

When JS is written, ink fragmentation rarely occurs. Furthermore, when the ink in the porous member 62 is consumed, a pressure difference between the ink in the porous member 61 and the porous member 62 immediately occurs due to the difference in average pore diameter, and the same amount of ink as the consumed amount is transferred to the porous member. The porous member 62 is replenished from the member 61 . At this time, the movement of the ink within the porous member 61 is also in the thickness direction, so that the ink is hardly divided. In this way, almost all of the ink in the porous member 61 is consumed while keeping fl equal to the state before use of the ink amount in the porous member 62, and after that, almost all of the ink is consumed VC.

上記のように、不実施例の構成をとることにより、イン
クタンク内のインク全はとんど残すことなく使用するこ
とができる。As described above, by adopting the configuration of the non-embodiment, all of the ink in the ink tank can be used without leaving anything behind.

きくなる状態を作り出すことができる。Is Figure 5 another example of non-invention? FIG. The other members except the porous member 60 have the same structure as the ink tank of the previous embodiment. The porous member 60 has a front portion and a rear portion having different thicknesses, and when the tank body 40 is filled, the front portion is compressed by the tank lid 50. For this reason, even if the porous material has a uniform average pore diameter, when the tank is filled with light, the average pore diameter will be small in the front part near the ink supply port, and the average pore diameter will become larger continuously as you move toward the rear VC. can create a state.

々に前方へと使い切られて行くことになる。The effect of the non-example is equivalent to arranging the porous members of this example so that the average pore diameter gradually increases from the front to the rear of thin plate-shaped porous ink tanks with slightly different average pore diameters. Therefore, it can be considered in the same way as the case of the above embodiment. Therefore, ink is consumed from the rear of the porous member φ, which is located far from the ink supply port, and is gradually used up toward the front.

このように、本実施例においては、−個の多孔質部材の

ため、構成が単純になるという効果金持つ。In this way, in this embodiment, a state in which the average pore diameters in the porous members are different can be created by using only - number of porous members, which has the advantage of simplifying the configuration.

Different capillary forces '41. It is composed of several parts, and is arranged so that the capillary force increases as it approaches the ink supply port, so all the ink in the tank can be used without leaving it, and the ink tank is stable. It has the effect of long life.
