Like Fig. 6 and shown in Figure 8, a plurality of connecting wall 370c of portion comprise: the 370c1 of first wall portion (Fig. 8), second 370c2 of wall portion (Fig. 8) and the 3rd wall portion that is the 370c3 of airside wall portion (Fig. 6).Under the situation of assembling print cartridges 30 as box unit 50 (Fig. 3 (A)), the 370c1 of first wall portion can be from outside Visual Confirmation, and second 370c2 of wall portion can be through opening end face housing 54 from outside Visual Confirmation (Fig. 3 (B)).In addition; Form perforated wall portion 370 (Fig. 6) and the 370b of opposed walls portion (Fig. 7) in a plurality of wall portion of liquid accommodating chamber 340, that have the plane vertical with the configuration direction (stacked direction, Y direction) of a plurality of print cartridges 30; Under situation as box unit 50 assembling print cartridges 30, can't be from outside Visual Confirmation.
As shown in Figure 6, the 370c3 of airside wall portion is the wall portion that erects the state of setting with respect to the face that is provided with (by the horizontal plane of X axle and Y axis convention) that print cartridge was set up under the user mode (liquid injection port 304 is towards the state of horizontal direction opening) at print cartridge 30.That is, the 370c3 of airside wall portion be under the user mode of print cartridge 30 from below towards above the wall portion of extending.Under the situation of present embodiment, the 370c3 of airside wall portion is to constitute the wall portion of print cartridge 30 with respect to the mode that mask is set has the angle of approximate vertical under the user mode of print cartridge.
Liquid injection port 304 is arranged at the 370c3 of airside wall portion in the following manner: under the user mode of print cartridge 30; Upper end 304p is towards horizontal direction (X axle positive direction) opening; Under the injection state of print cartridge 30, upper end 304p direction (X axle positive direction) opening on the vertical.Usually, 340 inject under the situation of inks from liquid injection port 304 towards the liquid accommodating chamber the person of utilization, the upper end 304p of liquid injection port 304 situation of direction opening on the vertical is injected liquid accommodating chamber 304 with ink more easily for the person of utilization.Therefore, through liquid injection port 304 being arranged in the above described manner the 370c3 of airside wall portion, can impel the person of utilization when injecting ink, to make print cartridge 30 become the injection state.And,, can easily form and can impel the person of utilization when injecting ink, to make print cartridge 30 become the liquid injection port 304 of injection state through liquid injection port 304 being set at the 370c3 of airside wall portion.Here; So-called " upper end 304p is towards the horizontal direction opening " is meant following relation: under the situation that under user mode, makes smooth paper and upper end 304p butt, the paper of institute's butt and horizontal direction angulation are in greater than 45 ° and in the scope below 90 °.And; So-called " upper end 304p towards vertical on direction opening " is meant following relation: under the situation that makes smooth paper and upper end 304p butt under the injection state, the paper of institute's butt and vertical angulation are in greater than 45 ° and in the scope below 90 °.
As shown in Figure 8, lower limit line LM1 and upper limit line LM2 are from the outstanding overshooting shape of the outer surface of the set 370c1 of wall portion of each line, 370c2, and integrally formed with toner cartridge main body 32.
A-4. the method for implanting of ink:
Fig. 9 is the figure that the few state of the ink surplus of liquid accommodating chamber 340 is shown.In addition, in fact, the liquid-receiver portion 202 of liquid leading-out portion 306 and odd-side 20 is connected via flexible pipe 24, but has omitted the diagram of flexible pipe 24.
As shown in Figure 9, when the ink of liquid accommodating chamber 340 is supplied to printer 12 and when being consumed, ink level descends, ink level arrives lower limit line LM1.Lower limit line LM1 is that to be illustrated in the amount of the ink of liquid accommodating chamber 340 under the user mode of print cartridge 30 few, is used to impel the person of utilization 340 to inject the mark of inks (replenishing ink) towards the liquid accommodating chamber.That is, lower limit line LM2 is used to point out the amount of the ink of the person's of utilization liquid accommodating chamber 340 to reach the mark of the situation of first threshold.Under near ink level arrives lower limit line LM1 the situation, the person of utilization is 340 injection (replenishing) inks towards the liquid accommodating chamber.Like this, liquid accommodating chamber 30 impels the person of utilization 340 to replenish inks towards the liquid accommodating chamber by lower limit line LM1, can prevent that thus printer 12 from not having to print under the state of ink in liquid accommodating chamber 340.Thus, can reduce air (bubble) by the possibility of 340 importing printers 12 from the liquid accommodating chamber.Thus, can prevent the generation (leak source etc.) of the unfavorable condition of printer 12.
When ink is injected in present dynasty liquid accommodating chamber 340, shown in arrow YR, make print cartridge 30 rotations, so that this print cartridge 30 becomes the state of opening above vertical of liquid injection port 304 towards the state of horizontal direction from the opening of liquid injection port 304.Thus, the state of print cartridge 30 is varied to the injection state from user mode.That is, print cartridge 30 can use with the upper end 304p of liquid injection port 304 direction open facing outward different user mode and these two states of injection state.
Figure 10 is used for the ink that injects ink towards print cartridge 30 is injected the figure that operation describes.Figure 10 (A) is illustrated in and makes the state of print cartridge 30 from the ink of print cartridge 30 inside of user mode (liquid injection port 304 is towards the state of horizontal direction opening) when being changed to the injection state under the state after ink level arrives lower limit line LM1.Figure 10 (B) is the figure that illustrates from liquid injection port 304 appearance of 340 injection inks towards the liquid accommodating chamber, and the state after ink level arrives upper limit line LM2 is shown.In addition, Figure 10 (A) and (B) be to observe the figure under the situation of print cartridge 30 from Y axle positive direction side.And at Figure 10 (A) and (B), in fact, the liquid-receiver portion 202 of liquid leading-out portion 306 and odd-side 20 is connected via flexible pipe 24, but has omitted the diagram of flexible pipe 24.In addition, Figure 10 (A) is illustrated in and makes print cartridge 30 become the state after the injection state unloads latch 302 afterwards.
Under user mode (liquid injection port 304 is towards the state of horizontal direction opening); The other end that second stream 350 that comprises air side opening 351 is positioned at than liquid injection port 304 is the position that bottom 304m leans on the below; But; Shown in Figure 10 (A), under the injection state of print cartridge 30 (state of liquid injection port 304 direction opening on the vertical), air side opening 351 is positioned at the position of leaning on the top than bottom 304m.And under the injection state, the upper end 304p of liquid injection port is opening towards the vertical top.And under the injection state, air receiving room 330 and liquid accommodating chamber 340 are along the vertical alignment arrangements, and air receiving room 330 is configured in the position of leaning on the top than liquid accommodating chamber 340.
When the state that under the few state of ink surplus, makes print cartridge is varied under the situation of injection state from user mode (liquid injection port 304 is towards the state of horizontal direction opening), liquid maintaining part 345 suppresses other the part that inks flow out to liquid accommodating chamber 340.That is, divide wall portion 342 and block flowing towards the ink of the direction of leaving from liquid outlet portion 349 (Z axle positive direction).Therefore, under the injection state, can keep the water level higher than other parts in liquid maintaining part 345.In more detail, can be utilized in division wall portion 342 that injection state decurrence reaches the position higher than liquid outlet portion 349 maintains the water level (liquid level) of the ink of liquid maintaining part 345 more than the height of liquid outlet portion 349.Thus, even if under the few situation of ink surplus, the ink in the liquid leading-out portion 306 and the ink continued presence of liquid maintaining part 345 and not the situation of air entrainment become possibility.Therefore, can reduce when injecting ink air (bubble), and flow into the possibility of odd-sides 20 via flexible pipe 24 from liquid outlet portion 349 influent leading-out portions 306.Thus, because air can not flow into record head 17 (Fig. 3) side when injecting ink, therefore can suppress because of sky sprays the leak source that causes, the quality that can suppress to typewrite reduces.
Shown in Figure 10 (B), use the additional operation of carrying out 340 additional inks with container 980 of taking in ink towards the liquid accommodating chamber.Particularly, from replenishing with container 980 ink droplet down to liquid accommodating chamber 340, thereby ink is added to liquid accommodating chamber 340.Upper limit line LM2 is in order to point out the person of utilization to be provided with from the situation that liquid injection port 304 injects inks and in liquid accommodating chamber 340, takes in the ink of enough amounts (liquid level arrives the amount of the degree that liquid injection port 304 and ink can not overflow from liquid injection port 304, second threshold value).Shown in Figure 10 (B), the person of utilization 340 injects inks arrive upper limit line LM2 up to the ink level of liquid accommodating chamber 340 degree towards the liquid accommodating chamber.That is, under the injection state, under the situation of the ink of taking in the degree that ink can not overflow from liquid injection port 304 in liquid accommodating chamber 340, air side opening 351 is positioned at the position of leaning on the top than ink level.Thus, when injecting ink, can prevent that ink is imported into air receiving room 330 via air side opening 351.
Figure 11 is used for the figure that the state to the inner ink of the print cartridge of user mode (liquid injection port 304 is towards the state of horizontal direction opening) 30 describes.Figure 11 illustrates when taking in liquid accommodating chamber 340 under the state of the ink of the degree of ink level arrival upper limit line LM2 under the injection state, has just made the state of print cartridge 30 after the injection state variation becomes user mode.In addition, also this state is called the state after just filling.Print cartridge 30 under the situation of observing from Y axle positive direction side shown in Figure 11.
Shown in figure 11, under the state after just filling, near liquid level (being also referred to as " atmosphere contact liquid level ") LA that atmosphere directly contacts is positioned at air side opening 351.Begin from this state, when being consumed because of the attraction print cartridge 30 inner inks from record head 17, near the ink level the air side opening 351 moves in second stream 350, in second stream 350, forms meniscus.After forming meniscus, the ink in the liquid accommodating chamber 340 is consumed, and the ink level in the liquid accommodating chamber 340 reduces gradually.And then; In the time of near the ink level in the liquid accommodating chamber 340 arrives lower limit line LM1; The person of utilization makes print cartridge 30 be changed to the injection state from user mode (liquid injection port 304 is towards the state of horizontal direction opening), 340 injects (replenishing) inks from liquid injection port 304 towards the liquid accommodating chamber.
Shown in figure 11, under the state after just filling, atmosphere contact liquid level LA is positioned at and highly is the scope of H1～H2.Therefore, even if under the state after just filling, also can be 12 stably supply with ink from print cartridge 30 towards printer.That is, under the state after just filling, the water-head d1a (being also referred to as " initial water potential difference d1a ") that produces because of the difference of the height of the vertical between atmosphere contact liquid level LA and the record head 17 is in and can stably supplies with in the prescribed limit of ink.
A-5. comparative example:
Figure 12 is used for the figure that the liquid injection system 1k to comparative example describes.The ink that Figure 12 illustrates print cartridge 30k is consumed, and the person of utilization is the state after the inner filling ink of print cartridge 30k just.The structure that is print cartridge 30,30k with the difference of embodiment is different, all is the structure same with embodiment and printer 12 (Fig. 1) waits other structure.The print cartridge 30k of comparative example is the state use of equal state with injection state and user mode.Therefore, print cartridge 30k is provided with liquid injection port 304k at second 370c2 of wall portion.And lower limit line LM1 and upper limit line LM2 all are arranged at the 370c1 of first wall portion.
When the inner ink of print cartridge 30k is consumed and the ink level of liquid accommodating chamber 340 arrives under the situation of lower limit line LM1, under the state of print cartridge 30k shown in Figure 12, the person of utilization injects (replenishing) to print cartridge 30k inside with ink from liquid injection port 304k.Consider that the person of utilization 340 injects situation about reaching with the ink of the same quantity of ink of the quantity of ink of being taken in an embodiment towards the liquid accommodating chamber here.That is, consider that the person of utilization is towards the inner situation of injecting ink up to ink level arrival upper limit line LM2 of print cartridge 30k.
For print cartridge 30k, different with the print cartridge 30 of present embodiment, under the injection state, comprise that second stream 350 of air side opening 351 is positioned at the position lower than the bottom 304m of liquid injection port 304k.Therefore, when ink was injected into liquid accommodating chamber 340, ink was imported into air receiving room 330 via second stream 350.Therefore, under the state after just filling, ink also is filled in air receiving room 330, and ink overflows from atmosphere open ports 318.When ink when atmosphere open ports 318 is overflowed, sheet component 316 (Fig. 4, Fig. 6) is soaked by ink and loses the original function of sheet component 316.And under the state after just filling, atmosphere contact liquid level LA is positioned at the position higher than record head 17.Thus, there is the situation that causes ink to spill because of hydraulic pressure from record head 17 from print cartridge 30.That is, initial water potential difference d1k during from stable state water-head d1 significantly squint, can take place can't be from print cartridge 30k towards printer 12 stably supply with ink the state of affairs.
