The partition wall 86 of the recess 73 and the partition wall 86 of the recess 74 are the same wall. That is, the recess 73 and the recess 74 share the partition wall 86.

  A notch 91 is formed at a portion of the partition wall 86 where the recess 74 and the recess 73 intersect. A portion of the partition wall 86 where the recess 74 and the recess 73 intersect is a portion of the partition wall 86 between the partition wall 83 and the partition wall 88. The notch 91 is formed in a direction that is concave in the Y-axis direction from the end of the partition wall 86 in the −Y-axis direction. For this reason, when the sheet member 72 is joined to the case 71, the recess 73 and the recess 74 communicate with each other through the notch 91. A space surrounded by the notch 91 and the sheet member 72 constitutes a communication path 92 (described later).

  Here, a recess 93 is provided in the recess 73. The recessed portion 93 is provided in a direction that is recessed toward the −X axis direction from the partition wall 83. Moreover, the recessed part 93 is provided in the direction which becomes concave toward the Y-axis direction. An ink supply port 95 is provided in the partition wall 94 that defines the recess 93.

The leg 98 protrudes toward the partition wall 84-Z axis direction. The legs 98 are utilized for positioning and fixing when the tank 10 is disposed in the first housing 51 (FIG. 3).

  As illustrated in FIG. 8, the tank 10 includes an ink storage unit 29 and an air introduction unit 101. The air introduction unit 101 includes a communication path 92, a buffer chamber 77, and an air communication path 102. The air introduction unit 101 is an air flow path between the outside of the tank 10 and the inside of the ink storage unit 29. In FIG. 8, a state in which a part of the tank 10 is cut is shown for easy understanding of the configuration of the atmosphere communication path 102 and the injection portion 45.

  The atmosphere introduction unit 101 communicates with the outside of the tank 10 in the atmosphere communication path 102. Further, the air introduction unit 101 communicates with the inside of the ink storage unit 29 in the communication path 92. The ink container 29 communicates with the outside of the tank 10 through the communication path 92, the buffer chamber 77, and the atmosphere communication path 102. In other words, the ink containing portion 29 is open to the atmosphere via the communication path 92, the buffer chamber 77, and the atmosphere communication path 102.

  The communication path 92 is an atmospheric flow path between the communication port 104 and the communication port 105. In the present embodiment, the communication path 92 is configured as a notch 91 formed in the partition wall 86. For this reason, in this embodiment, the path length of the communication path 92 is equal to the thickness dimension of the partition wall 86. The communication port 104 is defined as an opening formed at an intersection where the inner wall of the ink containing unit 29 and the communication path 92 intersect. In other words, the communication port 104 is a place where the communication path 92 is connected to the ink storage unit 29. The communication port 105 is defined as an opening formed at an intersection where the inner wall of the buffer chamber 77 and the communication path 92 intersect. In other words, the communication port 105 is a place where the communication path 92 is connected to the buffer chamber 77.

  The atmosphere communication path 102 is an atmospheric flow path between the atmosphere opening port 106 and the communication port 107. In the present embodiment, the atmosphere communication path 102 has a configuration including the introduction path 108 formed in the partition wall 87 and the thickness of the partition wall 87. Therefore, in this embodiment, the path length of the atmosphere communication path 102 is equal to the length obtained by adding the path length of the introduction path 108 and the thickness dimension of the partition wall 87. The atmosphere opening 106 is defined as an opening that opens toward the outside of the tank 10 in the atmosphere communication path 102. The communication port 107 is defined as an opening formed at an intersection where the inner wall of the buffer chamber 77 and the atmosphere communication path 102 intersect. In other words, the communication port 107 is a place where the atmosphere communication path 102 is connected to the buffer chamber 77. In this embodiment, the introduction path 108 is provided, but a configuration in which the introduction path 108 is omitted may be employed. In the tank 10 in which the introduction path 108 is omitted, the path length of the atmosphere communication path 102 is equal to the thickness dimension of the partition wall 87.

  The injection part 45 is provided in the partition wall 85. The cylindrical portion 45 </ b> A of the injection portion 45 is provided on the surface of the partition wall 85 facing upward, and protrudes from the partition wall 85 toward the side opposite to the ink containing portion 29 side. An ink introduction port 45B is opened at the upper end of the cylinder portion 45A opposite to the ink containing portion 29 side. On the other hand, an ink injection port 45C is opened at the intersection of the partition wall 85 where the surface on the ink containing portion 29 side and the cylinder portion 45A intersect. The ink injection port 45 </ b> C is an opening that opens toward the ink storage unit 29 in the partition wall 85 of the injection unit 45. The ink injected from the ink introduction port 45B flows from the ink injection port 45C into the ink containing portion 29 via the cylinder portion 45A. The ink injection port 45C corresponds to a liquid injection port.

  The buffer chamber 77 is located at a position in the Z-axis direction of the ink storage unit 29. That is, the buffer chamber 77 is located above the ink storage unit 29. The ink storage portion 29 and the buffer chamber 77 of the ink storage portion 29 are arranged in the vertical direction with the partition wall 86 interposed therebetween. The injection unit 45 is formed above the ink storage unit 29 and is located at a position in the X-axis direction from the buffer chamber 77.

  In the tank 10, the partition wall 83 is located at a position in the X-axis direction from the partition wall 89. For this reason, the partition wall 89 and the partition wall 83 have a step in the X-axis direction. Therefore, the buffer chamber 77 is displaced from the ink storage unit 29 in the −X axis direction.

  As the print head 55 prints, the ink in the ink storage unit 29 is sent to the print head 55 side. For this reason, with the printing by the print head 55, the pressure in the ink accommodating part 29 becomes lower than atmospheric pressure. When the pressure in the ink containing portion 29 becomes lower than the atmospheric pressure, the atmosphere in the buffer chamber 77 is sent into the ink containing portion 29 through the communication path 92. Thereby, the pressure in the ink containing part 29 is easily maintained at atmospheric pressure. The atmosphere flows into the buffer chamber 77 from the atmosphere opening port 106 through the atmosphere communication path 102 and the communication port 107 in this order. As described above, the ink in the tank 10 is supplied to the print head 55. When the ink in the ink storage unit 29 in the tank 10 is consumed and the remaining amount of ink decreases, the operator can inject new ink into the ink storage unit 29 from the injection unit 45.

  In the tank 10, for example, when the posture of the tank 10 changes when the printer 1 is transferred, even if the ink in the ink storage unit 29 flows into the atmosphere introduction unit 101, the ink is supplied to the buffer chamber 77. Easy to fasten. For this reason, in the tank 10, the risk that the ink in the ink containing portion 29 leaks out of the tank 10 from the atmosphere opening 106 can be kept low.

  Here, as described above, in the tank 10, the partition wall 89 and the partition wall 83 have a step in the X-axis direction. That is, the buffer chamber 77 is displaced from the ink storage unit 29 in the −X axis direction. With this configuration, the space forming portion 120 is formed between the partition wall 83 and the housing 6. In a broad sense, the space forming unit 120 is a space defined by the tank 10 and the housing 6. According to this definition, the space between the partition wall 89 of the tank 10 and the housing 6 is also included in the space forming unit 120.

The space forming unit 120, which is an example of a low heat transfer unit, reduces heat conduction from each heat source to the ink storage unit 29. Thereby, in the printer 1, since the low heat transfer unit is disposed between the heat source and the ink storage unit 29, it is possible to suppress the heat from the heat source from being transmitted to the ink in the ink storage unit 29. According to the present embodiment, it is possible to provide the printer 1 in which the influence of the heat source is considered on the ink in the ink storage unit 29.

That is, the cover 401 rotates in the Y-axis direction of the printer 1000.

  As shown in FIG. 17, in the printer 1000, a plurality (four in this example) of tanks 400 are accommodated in the housing 6. In the printer 1000, the plurality of tanks 400 are located on the front 22 side of the printer 1000, that is, on the Y axis direction side of the printer 1000. In the printer 1000, a plurality of tanks 400 are arranged along the X axis. Therefore, in the printer 1000, the X-axis direction is a direction in which the plurality of tanks 400 are arranged.

  The cover 401 is provided with a window portion 25. The window portion 25 is provided on the front surface 22 of the housing 6. The window part 25 has optical transparency. A tank 400 is provided at a position overlapping the window portion 25. For this reason, the worker who uses the printer 1000 can visually recognize the tank 400 through the window portion 25. In the present embodiment, the window portion 25 is provided as an opening formed in the cover 401. And the window part 25 provided as opening is obstruct | occluded with the member 403 which has a light transmittance. For this reason, the operator can visually recognize the visual recognition wall 404 of the tank 400 through the window part 25 which is an opening. Note that a configuration in which the member 403 that closes the window portion 25 is omitted may be employed. Even if the member 403 that closes the window 25 is omitted, the operator can visually recognize the viewing wall 404 of the tank 400 through the window 25 that is an opening.

  In the present embodiment, at least a part of the viewing wall 404 of the tank 400 has light transmittance. The ink in the tank 400 can be visually recognized from the site | part which has the light transmittance of the visual recognition wall 404. FIG. That is, the liquid level in the tank 400 can be visually recognized from the portion of the visual recognition wall 404 having light transmittance. Therefore, the operator can visually recognize the amount of ink in each tank 400 by visually recognizing the four tanks 400 through the window portion 25. That is, in the tank 400, the portion having the light permeability of the visual recognition wall 404 can be used as a visual recognition unit that can visually recognize the amount of ink. Note that a configuration in which the entire viewing wall 404 has light transmittance may be employed.

  In the tank 400 of the printer 1000, the injection unit 45 is provided on the wall 405 as shown in FIG. The wall 405 is inclined when the printer 1000 is used. The wall 405 is inclined in the direction toward the −Y axis direction from the −Z axis direction toward the Z axis direction. For this reason, the wall 405 faces the direction intersecting the vertical direction. The aforementioned viewing wall 404 extends in a direction intersecting the wall 405.

  In the tank 400 of the modified example 7, as shown in FIG. 19, a space is formed above the ink 407 in a state where the ink 407 in the ink containing portion 29 has reached the upper limit mark 48. In the tank 400 of Modification Example 7, the space formed above the ink 407 is configured as a buffer chamber 77. The atmosphere opening 106 is opened in the wall 408 that partitions the buffer chamber 77.

  Also in the tank 400 of the modified example 7, the buffer chamber 77 can constitute the space forming portion 123. In the tank 400 according to the modified example 7, the ink containing portion 29 and the space forming portion 123 are arranged along the Z axis that is the vertical direction of the printer 1000. That is, in the modified example 7, the ink storage unit 29, the space forming unit 123, which is an example of the low heat transfer unit 131, and the heat source 129 can be easily arranged in the vertical direction. Also in the modified example 7, the configuration in which the space forming unit 123 is disposed between the heat source 129 and the ink storage unit 29 can suppress the transfer of heat from the heat source 129 to the ink in the ink storage unit 29.

(Modification 8)
The tank set 410 of the modification 8 is demonstrated. As shown in FIG. 20, the tank set 410 has a configuration in which a buffer unit 411 is added to the tank 400. In the modification 8, about the structure similar to the modification 7, the same code | symbol as the modification 7 is attached | subjected and detailed description is abbreviate | omitted.

  In the tank set 410 of the modified example 8, the tank 400 and the buffer unit 411 communicate with each other through a pipe 128 such as a flexible tube. The buffer unit 411 has a container-shaped air accommodating part 412 that can accommodate air. The ink storage unit 29 of the tank 400 and the buffer unit 411 communicate with each other through a pipe 128. If the tube 128 is formed of a flexible tube or the like, the degree of freedom of arrangement of the buffer unit 411 can be increased, so that the printer 1000 can be easily downsized.

  In the printer 1000 that employs the tank set 410, by arranging the buffer unit 411 between the heat source 129 and the ink storage unit 29, the buffer unit 411 can be a space forming unit 123 that is an example of the low heat transfer unit 131. . In the modification 8, the space forming unit 123 that is an example of the low heat transfer unit 131 is disposed between the heat source 129 and the ink storage unit 29, so that the heat from the heat source 129 is applied to the ink in the ink storage unit 29. It is possible to further reduce the transmission.

  Further, in the tank set 410 of the modified example 8, the tank 400 and the buffer unit 411 are arranged along the Y axis that is the front-rear direction of the printer 1000. That is, in the modification 8, the ink storage part 29, the space forming part 123, which is an example of the low heat transfer part 131, and the heat source 129 are arranged in the front-rear direction. In the printer 1000, the heat source 129 is often arranged on the back side. Therefore, as in Modification 8, the ink storage portion 29 is disposed on the front surface side, and the space forming portion 123 that is an example of the low heat transfer portion 131 is disposed between the ink storage portion 29 and the heat source 129. Therefore, enlargement can be suppressed. Further, in the tank set 410 of the modified example 8, since the degree of freedom of the arrangement of the space forming unit 123 is increased, it is arranged at a position effective for reducing heat conduction among the positions between the heat source 129 and the ink containing unit 29. It's easy to do.

(Modification 9)
In the tank 400 of the modified example 7, the ink containing portion 29 and the space forming portion 123 are arranged in the vertical direction. However, a configuration in which the ink containing portion 29 and the space forming portion 123 are arranged in the front-rear direction can also be employed. A configuration in which the ink containing portion 29 and the space forming portion 123 are arranged in the front-rear direction will be described as a tank 413 of the ninth modification.

  In the tank 413, as shown in FIG. 21, a partition wall 414 is provided inside. The partition wall 414 is one of the walls that partition the ink storage unit 29. A part of the buffer chamber 77 is disposed behind the ink containing portion 29 with the partition wall 414 interposed therebetween. In the tank 413, compared to the tank 400, the buffer chamber 77 can be regarded as being extended to the rear of the ink storage unit 29. By the tank 413, the ink containing portion 29 and the space forming portion 123 can be arranged in the vertical direction and the front-rear direction. Thereby, the space formation part 123 which is an example of the low heat-transfer part 131 can be arrange | positioned between the ink accommodating part 29 and the heat source 129 with respect to both the up-down direction and the front-back direction. For this reason, it is possible to further suppress the heat from the heat source 129 from being transmitted to the ink in the ink containing portion 29.

  In addition, the structure which applied the modification 1-6 mentioned above individually or in combination with respect to each of the modifications 7-9 may also be employ | adopted.
