It should be noted that the ink tank 15 in FIG. 3 is shown in the "first posture state" described later in FIG.

As shown in FIG. 3, an indicator 155 indicating the amount of ink in the ink containing chamber 33 is formed on the front side of the ink tank 15 in the front-rear direction. An ink inlet 21 for injecting ink into the ink containing chamber (into the liquid containing chamber) is arranged on the inclined surface on the upper front side of the ink tank 15 . A tank cap 22 is detachably attached to the ink inlet 21 . In this embodiment, an ink containing chamber 33 for containing ink is arranged above the ink tank 15 in the direction of gravity, and a buffer space 34 for temporarily containing ink is arranged below the ink tank 15 . . The ink injection port 21 communicates with the ink containing chamber 33 and receives injection of ink from the outside of the ink tank 15 . The ink tank 15 and the ink inlet 21 respectively constitute a liquid storage container (liquid storage member) and a liquid injection section according to the present invention. The ink storage chamber 33 and the buffer space 34 constitute the liquid storage chamber and the air communication chamber, respectively, in the present invention.

The ink containing chamber 33 and the buffer space 34 communicate with each other via a communication channel 35 . In this embodiment, the ink containing chamber 33 and the buffer space 34 share a portion of the bottom surface of the ink containing chamber 33 so as to serve as the ceiling surface of the buffer space 34 . It can be said that the bottom surface of the ink containing chamber 33 and the ceiling surface of the buffer space 34 constitute a partition wall 36 that partitions the ink containing chamber 33 and the buffer space 34 .

As shown in FIG. 3, the communication channel 35 is arranged on the lower front side of the ink tank 15 . In the first posture of the ink tank 15 , one end of the communication channel 35 is connected to the bottom surface of the ink containing chamber 33 and the other end of the communication channel 35 is connected to the bottom surface of the buffer space 34 . Further, in the ink tank 15 of this embodiment, the ink storage chamber 33, the buffer space 34, and the communication flow path 35 are integrally formed.

The ink outflow portion 141 communicates with the ink containing chamber 33 to flow out and supply the ink to the recording head 13 .

In the ink tank 15 of the present embodiment, when the air in the ink storage chamber 33 expands due to atmospheric pressure fluctuations or temperature changes, the ink pushed out by the expanded air is buffered in the same manner as the ink tank described in Patent Document 1. It can be stored in the space 34 . With such a configuration, it is possible to prevent the ink, which is pushed out by the expanded air and flows back through the atmosphere communication channel 23 , from leaking from the atmosphere opening 24 .

FIG. 4 is a schematic diagram showing a cross section of the ink tank 15 in this embodiment. 4A is a schematic diagram showing the ink tank 15 in the second posture, and FIG. 4B is a schematic diagram showing the ink tank 15 in the first posture. 4(c) is a cross-sectional view taken along line α-α of FIG. 4(b). In this embodiment, the ink tank 15 is detachable from the recording apparatus 11, and can be changed between a first posture state and a second posture state before and after detachment. Note that, in this embodiment, the ink outflow portion 141 is connected to the ink flow path 14 even after attachment/detachment.

FIG. 4(a) shows the second posture state, which is the posture of the ink tank 15 when ink is injected. The second posture refers to a posture in which the ink tank 15 is arranged so that the buffer space 34 and the ink containing chamber 33 are aligned in the horizontal direction. Furthermore, when the ink tank 15 is in the second position, the ink inlet 21 and the communication channel 35 are positioned above the ink tank 15, and the ink outflow portion 141 is positioned below the ink tank 15. . After the ink tank 15 is detached from the recording apparatus 11, the ink tank 15 is tilted so that the communication channel 35 and the ink inlet 21 are on the upper side (upper side in the Y-axis direction). Ink can then be injected into the ink tank 15 after the tank cap 22 is removed. In the second posture state, even if ink is injected from the ink inlet 21, the communication channel 35 is always positioned above the liquid surface of the ink 19 in the ink containing chamber 33. Therefore, the ink 19 flows through the communication channel 35. does not flow into the buffer space 34 through the After ink is injected, the ink inlet 21 of the ink tank 15 is closed with a tank cap 22 .

In this embodiment, when ink is injected, in the second posture (see FIG. 4A), the liquid surface in the ink tank 15 exceeds the height position (Zh) of the ejection port formation surface of the head. If the height position is not high, ink can be injected into the ink tank 15 without providing an opening/closing valve in the ink flow passage 14 . That is, in the second posture, even when the ink inlet 21 is open, there is a head difference necessary to maintain the negative pressure in the head, and the risk of ink leaking from the head is reduced.

Further, when an on-off valve is provided in the ink flow passage 14, it is not necessary to consider the position of the ink tank (water head difference) at the time of ink injection, and the leakage of ink at the time of ink injection can be reduced more reliably.

FIG. 4(b) shows a first attitude state, which is the attitude of the ink tank 15 when it is attached to the recording apparatus 11 after ink is injected. The first posture refers to a posture in which the buffer space 34 is positioned below the ink containing chamber 33 in the direction of gravity. The ink tank 15 of this embodiment is attached to the recording apparatus 11 in the first posture state. At this time, since the ink inlet 21 of the ink tank 15 is sealed by the tank cap 22 , air does not enter the ink tank 15 through the ink inlet 21 . In the first posture, one end of the communication channel 35 is connected to the bottom side of the ink containing chamber 33 and the other end is connected to the bottom side of the buffer space 34 . The communication channel 35 and the opening 32 are arranged on the lower front side of the ink tank 15 (the front side in the Y-axis direction), and the atmosphere opening 24 is arranged on the upper rear side of the ink tank 15 (the Z-axis direction is upper side).

Further, as shown in FIG. 4C, in the first posture state, the opening 32 of the communication channel 35 in the buffer space 34 is formed on the bottom surface of the buffer space 34 toward the upper side in the direction of gravity. there is With this configuration, a meniscus is formed at the opening 32 of the communication channel 35 , so that the ink in the ink containing chamber 33 does not flow out to the buffer space 34 ahead of the opening 32 .

FIG. 5 is a schematic cross-sectional view showing the ink-filled state of the ink tank 15 and the recording head 13 in the recording apparatus 11 of this embodiment. The tube 51 communicates from the ink outflow portion 141 of the ink tank 15 to the recording head 13 and is used to flow out and supply the ink 19 in the ink containing chamber 33 to the recording head 13 . In this embodiment, the ink outflow portion 141 and the tube 51 constitute the ink flow path 14 . Also, the tube 51 constitutes the second communication flow path of the present invention.

FIG. 5A shows a state in which the ink in the ink containing chamber 33 is filled up to the inside of the recording head 13 through the ink flow path 14 . When the ink of the recording head 13 is ejected from the ejection section 131 in the state in which the ink is filled as shown in FIG. can be done.

In FIG. 5(a), the arrow indicates the direction of gravity, and "height" in the description of FIGS. 5 and 8 means the height in the direction of gravity.

Let Zh be the height of the ejection port formation surface, which is the surface on which the ejection portions 131 are arranged in parallel, and Z0 be the lowest position in the ink flow path 14, which is the flow path connecting the ink outflow portion 141 and the recording head 13. do. In this embodiment, the ink outflow portion 141 is provided at the same height as the bottom surface of the ink containing chamber 33 (the partition wall surface of the partition wall 36).

Furthermore, the height of the position of the opening 32 in the communication channel 35 is Z1. At this time, the height Z1 corresponds to the liquid surface height of the ink at which gas-liquid exchange between the ink and the atmosphere occurs as the ink is consumed by the recording head 13 .

As described above, the buffer space 34 is located below the ink containing chamber 33 in the direction of gravity, so the position (Z1) of the opening 32 is below the height (Zh) of the ejection port forming surface of the recording head 13. placed in With such a configuration, the printing apparatus 11 of the present embodiment can generate a water head difference between Zh and Z1, and can maintain a favorable negative pressure inside the printing head 13 . In addition, in the recording apparatus 11 of the present embodiment, a meniscus is also formed in the ejection port (ejection portion 131) to prevent the ink from flowing back into the ink containing chamber 33 due to air entering from the ejection port.

FIG. 5B shows a state in which the air in the ink containing chamber 33 expands due to atmospheric pressure fluctuations and temperature changes, and the ink 19 in the ink containing chamber 33 is pushed out into the buffer space 34 . The height Z2 of the ink surface in the buffer space 34 corresponds to the height at which gas-liquid exchange between the ink and the atmosphere is performed.

The height Z2 of the ink liquid surface is arranged below the height (Zh) of the ejection opening formation surface of the recording head 13 . Therefore, even if the ink 19 is pushed out into the buffer space 34 , the negative pressure in the printhead 13 does not immediately reverse to positive pressure, and the ink hardly leaks out from the printhead 13 .

Also, if the height (Z2) of the ink liquid surface in the buffer space 34 is limited to the position (Z0) of the partition wall surface, which is the surface of the partition wall 36, it is always lower than the height of the ejection port formation surface of the recording head 13. Therefore, the negative pressure in the recording head can be stably maintained.

Further, if the height (Z2) of the ink surface in the buffer space 34 is limited to below the position (Z0) of the partition wall, and the lowest position in the ink flow path 14 is also set above the position (Z0) of the partition wall, , the ink flow path 14 is always positioned higher than the level of the ink surface (Z2). Therefore, even if air enters the ink flow path 14, the negative pressure inside the print head can be maintained satisfactorily. With such a configuration, the printing apparatus 11 of the present embodiment can maintain a favorable negative pressure inside the printing head 13 even when ink is stored in the buffer space 34 .

As described above, the ink tank 15 of this embodiment has the first posture in which the buffer space 34 is positioned below the ink containing chamber 33 in the direction of gravity, and the first posture in which the buffer space 34 and the ink containing chamber 33 are arranged in parallel in the horizontal direction. and a second posture to move. With such a configuration, the recording apparatus 11 of the present embodiment does not communicate air from the ink inlet 21 while the negative pressure of the recording head 13 is well maintained. Therefore, even with the configuration in which the ink tank 15 is provided with the ink inlet 21, ink leakage to the outside can be suppressed when ink is injected.
