[Figure 14] This is a schematic diagram of the micro-machined surface according to the first to third embodiments. [Modes for carrying out the invention]

[0009] (First Embodiment) First, we will describe the outline of an inkjet recording apparatus as an example of a liquid ejection apparatus according to the present invention. Figure 1 is a schematic diagram of the inkjet recording apparatus according to this embodiment.

[0010] The inkjet recording device 1 (hereinafter referred to as recording device 1) is equipped with a paper feed roller (not shown), and the recording media loaded in the paper feed tray A are fed one by one by the paper feed roller. The fed recording media are placed between the transport roller 7 and the pinch roller 8 and transported in the +Y direction in the figure. The back surface of the transported recording media is supported by the platen 3, and the distance between the nozzle (not shown) of the recording head 4, which is the liquid ejection head, and the recording media, which is the liquid ejection medium, is maintained at a constant or predetermined distance. In this state, ink, which is a liquid containing a colorant, is ejected from the nozzle of the recording head 4 onto the recording media, thereby recording onto the non-recording medium.

[0011] The recording head 4 has nozzles for discharging ink which is a liquid, and is mounted on the carriage 2. The carriage 2 reciprocates in the X direction on the carriage rail 101 by drive means such as a motor. The recording head 4 discharges ink droplets while moving in the main scanning direction together with the carriage 2, and records an image for one band on the recording medium on the platen 3. When an image for one band is recorded, the recording medium is conveyed in the conveyance direction by a predetermined amount by the conveyance roller 7 (intermittent conveyance operation). By repeating this recording operation for one band and the intermittent conveyance operation, an image is recorded on the recording medium based on the image data. The recording medium on which the recording by the recording head 4 has been completed is fed between a paper discharge roller (not shown) and a platen, and is discharged to the paper discharge tray 9.

[0012] Further, the recording apparatus 1 is provided with ink tanks 6 which are a plurality of independent liquid storage containers corresponding to the colors of the ink discharged from the recording head 4. The ink tanks 6 and the recording head 4 are connected via joints (not shown) by tubes 5 (see FIG. 3) corresponding to the colors of the ink respectively. Thereby, it becomes possible to individually supply the ink of the color stored in each ink tank 6 to the nozzles of the recording head 4 corresponding to each ink color.

[0013] The recording apparatus 1 is provided with a cap portion 10 that covers the surface on which the nozzles of the recording head 4 are formed. The cap portion 10 is formed of a flexible material, and is configured to be movable between a capping position that covers the ink discharge portion 81 of the recording head 4 and a separation position that does not cover the ink discharge portion 81. The cap portion 10 is connected to a pump (not shown). When the pump is driven in a state where the cap portion 10 is in the capping position, the inside of the cap portion 10 becomes negative pressure and ink is sucked from the recording head 4. Thereby, the ink discharge performance of the recording head 4 is restored. Also, by positioning the cap portion 10 in the capping position in a standby state where the recording head 4 is not performing a recording operation, the time during which the nozzles of the recording head 4 are exposed to the atmosphere is reduced, and it also has the role of suppressing ink discharge failure due to drying of the nozzles.

[0014] As shown in FIG. 2, the recording apparatus 1 is covered by a housing 100. Openings 103a, 103b, 103c, and 103d are provided in the housing 100 corresponding to the arrangement positions of the ink tanks 6, and through these openings, the user can visually recognize the ink tanks 6 from the front. This enables the user to visually confirm the remaining amount of ink stored in the ink tanks 6. The ink tank 6 in the present embodiment can be filled with ink from an ink filling port 17 (see FIG. 4) which is a liquid injection part, and the ink filling port 17 is closed by a plug member 102. The plug member 102 is configured to be movable between a closed position covering the ink filling port 17 and an open position opening the ink filling port 17.

[0015] The recording apparatus 1 is provided with a cover 101, and the cover 101 is configured to be rotatable between a closed position covering the interior of the apparatus and an open position opening the interior of the apparatus. When the user fills the ink tank 6 with ink, the cover 101 and the plug member 102 are moved to the open position, and ink is filled with the ink filling port 17 being open.

[0016] FIG. 3 is a diagram showing the configuration of the ink supply unit. FIG. 3(a) is a perspective view of the ink supply unit, and FIG. 3(b) is a front view of the ink supply unit as viewed from the Y direction. The recording apparatus 1 is provided with four ink tanks 6B, 6C, 6M, and 6Y corresponding to black, cyan, magenta, and yellow inks, and each color ink is stored in each ink tank 6. The number of ink tanks 6 and the colors of the inks do not have to be the four colors described above, and the number of ink colors and the number of ink tanks 6 do not have to be four. Also, a plurality of ink tanks 6 storing the same color ink may be provided. Each ink tank 6 is mounted on the recording apparatus 1 in a posture such that the ink filling port 17 faces upward.

[0017] Each ink tank 6 is connected to the recording head 4 via a tube 5, as described above. The tube 5 extends in the X direction as shown in Figure 3, bends midway, and connects to the recording head 4. The bend in the tube 5 moves along with the movement of the recording head 4. The tube guide plate 15 guides the position of the tube 5 when the recording head 4 moves. A tube guide sheet 14 is placed at the points where the tube 5 comes into contact with the housing 100 or the tube guide plate 15 when it moves along with the recording head 4, thereby reducing friction on the tube 5 and reducing wear on the tube 5. One end of the tube guide sheet 14 is fixed to the tube guide plate 15, and the other end is fixed to the recording head 2, so that the tube guide sheet 14 can move along with the tube 5 as the recording head 4 moves back and forth.

[0018] Furthermore, the multiple tubes 5 extending from each ink tank 6 are held together by a holder slider 11, a first tube holder 12, and a second tube holder 13. The first tube holder 12 reduces contact between the tube 5 and the aforementioned tube guide sheet 14. The second tube holder 13 plays a role in fixing the ends of the tubes 5 by clamping them between itself and the tube guide plate 15.

[0019] Figure 4 is a perspective view of the ink tank 6. The ink tank 6 is a five-sided integrally molded product, and an ink chamber, which is a storage section for ink, is formed by welding a film 24 to the tank opening. The ink tank 6 is made of transparent or translucent resin, and the ink contained in the ink chamber and the ink level can be seen from the viewing surface 16, allowing the remaining ink level to be visually checked.

[0020] The visible surface 16 of the ink tank 6 has a lower limit scale 16a and an upper limit scale 16b protruding from it, as an example of a scale. The lower limit scale 16a is a scale indicating the minimum amount of ink to be injected into the ink chamber. The upper limit scale 16b is a scale indicating the maximum amount of ink that can be injected from the ink inlet 17 and contained in the ink chamber. In addition to the above-mentioned scales 16a and 16b, other scales may also be provided, or only one of them may be provided.

[0021] Figure 5 is a perspective view showing the opening and closing of the stopper member 102, and Figure 6 is a YZ cross-sectional view showing the opening and closing of the stopper member 102. As described above, the stopper member 102 is a member that can move between an open position that opens the ink injection port 17 and a closed position that closes the ink injection port 17. The stopper member 102 is held by a retaining member 105, and the retaining member 105 is further rotatably supported by a pivot shaft 104b provided on the housing 104. As a result, the retaining member 105 is positioned relative to the housing 104 and rotates between an open position that opens the ink injection port 17 and a closed position that closes the ink injection port 17.

[0022] The housing 104 is fixed in position relative to the ink tank 6 by the engagement of the mating portion 104a with the rib 18 provided on the ink tank 6, which will be described later.

[0023] Figure 7 is a YZ cross-sectional view of the ink injection container being inserted into and removed from the ink tank 6. The ink inlet 17 of the ink tank 6 is configured so that the ink injection container 50, which is a liquid injection container, can be inserted in the approximately Z direction, which intersects the XY direction. When a user injects ink from the ink injection container into the ink tank 6, they insert the ink injection container 50 into the ink inlet 17 as shown in Figure 5(a), and inject ink from the ink injection container 50 into the ink tank 6. After the injection of ink from the ink injection container 50 into the ink tank 6 is complete, they remove the ink injection container 50 from the ink inlet 17 as shown in Figure 5(b).

[0024] Figure 8 is a perspective view of the area around the ink inlet 17 of the ink tank 6. When ink is injected into the ink tank 6 using the ink injection container 50, there is a risk that ink may spill from the ink injection container 50 or the ink inlet 17, staining the side of the ink tank 6. In particular, if spilled ink adheres to the viewing surface 16 of the ink tank 6, it will obstruct the user's ability to see the amount of ink in the ink tank 6. Furthermore, if the recording device 1 is subjected to an impact or its posture changes while ink has spilled on the side of the ink tank 6, there is a possibility that ink may splatter and adhere to surrounding parts of the ink tank 6, potentially staining the user's hands if they touch them. As described above, in order to prevent ink from adhering to the viewing surface 16 of the ink tank 6 and its surrounding parts, measures must be taken to prevent the spread of ink spilled from the ink inlet 17 and the ink injection container 50.

[0025] In this embodiment, an ink-holding member 20 made of an absorbent material capable of absorbing liquid is arranged near the ink inlet 17 of the ink tank 6, as shown in Figure 6(a). In addition, arc-shaped projections called ribs 18, 19a, and 19b are provided around the ink inlet 17, and a linear projection called rib 26 is provided extending from the ink inlet 17 toward the ink-holding member 20. The rib 18 has an arc shape with an opening 18a in the portion facing the ink-holding member 20.

[0026] Ribs 19a and 19b are configured to be lower in height in the Z direction than rib 18, and rib 19a has an opening 191a similar to the opening 18a of rib 18. Rib 19a is also connected to rib 19c which extends from the opening 191a toward the ink holding member 20. Rib 19b also has an arc shape with an opening in the part facing the ink holding member 20. Ribs 19a and 19b, and the aforementioned rib 26, are in contact with the ink holding member 20. As described above, the formation of ribs around the ink injection port 17 forms an ink guide path 21, which is a liquid guide section, and an ink holding path 25. It is desirable that the heights of ribs 19a, 19b, and 19c are such that they do not obstruct the mating of rib 18 with mating section 104a.

[0027] The flow of ink into the ink guide channel 21 will be explained using Figure 6(b). When a user injects ink into the ink tank 6, they remove the ink injection container 50 from the ink inlet 17 as shown in Figure 5(b). At this time, ink may adhere to the outer surface 22 of the ink inlet 17. The ink adhering to the outer surface 22 of the ink inlet 17 falls downward due to gravity. The fallen ink enters the ink guide channel 21, and as the amount of ink flowing into the ink guide channel 21 increases, the ink flows along the rib 18 and flows toward the opening 18a as indicated by the arrow.

[0028] The ink that reaches the opening 18a then travels along the rib 26 and, upon reaching the ink holding member 20, is absorbed and held by the ink holding member 20. At this time, the rib 19c prevents the ink from diffusing in the X direction, ensuring that the ink is reliably guided to the ink holding member 20. This allows the ink to be moved from the ink injection port side (liquid injection part side) to the ink holding member 20.

[0029] If ink overflows from the ink guide channel 21, the ink that has exceeded the rib 18 flows into the ink holding channel 25, as shown by the arrow in Figure 6(c), and the incoming ink is held in place by capillary force. As the ink held in the ink holding channel 25 dries over time, even if ink overflows from the ink guide channel 21 again, the ink will be held in the ink holding channel 25, and the diffusion of the ink outside the ink holding channel 25 will be suppressed. In this way, in the ink tank 6, the ink holding member 20 and the ink holding channel 25 function as liquid holding means, suppressing the diffusion of ink.

[0030] With the above configuration, ink adhering to the outer surface 22 of the ink injection port 17 is guided to and held in the ink holding member 20 by the ink guide path 21. Furthermore, even if ink overflows from the ink guide path 21, the ink is held in the ink holding path 25. This prevents the spilled ink from spreading, and because the ink is held in the ink holding member 20, it also prevents ink from scattering when the posture of the recording device 1 changes. In addition, since the volume of the ink holding member 20 can be reduced by the amount of ink that can be held in the ink holding path 25, the ink holding member 20 can be made smaller.

[0031] Furthermore, two or more ink holding passages 25 may be provided by adding additional ribs outside of ribs 19a and 19b. Also, in this embodiment, it is possible to hold ink in the gap between rib 19a and rib 18, so even if only rib 19a is provided and rib 19b is not provided, it is possible to hold ink that overflows from the ink guidance passage 21. However, by increasing the number of ink holding passages 25, it becomes possible to hold more ink compared to the state in Figure 6 where there is only one ink holding passage 25. This makes it possible to cope even when the amount of ink overflowing from the ink guidance passage 21 increases, and the effect of suppressing ink diffusion can be enhanced compared to when there is only one ink holding passage 25.

[0032] Furthermore, the rib 18 may be extended so that the opening 18a contacts the ink holding member 20, as shown in Figure 9(a). This makes it possible to guide ink from the ink guide path 21 to the ink holding member 20 even when the rib 26 shown in Figure 6 is not provided.

[0033] Furthermore, in this embodiment, the ribs 19a and 19b provided around the rib 18 are made in an arc shape, bringing the ink holding passage 25 closer to the rib 18 and creating a structure that allows ink overflowing from the ink guide passage 21 to quickly flow into the ink holding passage 25. However, the shape of the ink holding passage 25 does not have to be an arc shape; any shape that surrounds the outside of the rib 18 can hold the ink overflowing from the ink guide passage 21. For example, the ink holding passage 25 may be constructed by providing ribs 19a and 19b in a rectangular shape as shown in Figure 9(b), or it may be in a shape other than a rectangle.

[0034] (Second Embodiment) The second embodiment will be described below, but the same configuration as the first embodiment described above will be omitted from the explanation.

[0035] Figure 10 is a perspective view of the area around the ink inlet 17 of the ink tank 6 in this embodiment, and Figure 11 is an enlarged cross-sectional view of the ink tank 6 cut in the YZ plane including the ink inlet 17. In this embodiment, an arc-shaped groove 23 is provided around the rib 18. A rib 201 extending to the ink holding member 20 is provided near the opening of the groove 23, and further guides the ink guided to the opening 18a by the ink guide path 21 to the ink holding member 20. When the ink guided to the ink holding member 20 by the rib 201 reaches the ink holding member 20, the ink is absorbed and held by the ink holding member 20.

[0036] Furthermore, in this embodiment, as in the first embodiment, if ink overflows from the ink guide path 21, the overflowing ink flows into the groove 23, and the ink is held in the groove 23 by capillary force. With this configuration, the ink that flows into the ink guide path 21 is guided to and held in the ink holding member 20 or the ink holding path 25, thereby suppressing the widespread diffusion of the ink.

[0037] In this embodiment, two grooves 23 are provided, but there may be two or more grooves 23, or there may be just one. Increasing the number of grooves 23 increases the amount of ink that can be held in the grooves, so it can handle an increase in the amount of ink overflowing from the ink guide path 21. Furthermore, it is possible to reduce the volume of the ink holding member 20 by the amount of ink that can be held in the grooves 23, thus enabling miniaturization of the ink holding member 20.

[0038] Furthermore, in this embodiment as in the first embodiment, the rib 18 may extend so that the opening 18a contacts the ink holding member 20. Also, the shape of the groove 23 does not have to be an arc shape; it may be a shape that can surround the rib 18, and may be formed as a rectangle or other shape.

[0039] (Third embodiment) The third embodiment will be described below, but the same configuration as in the first and second embodiments will not be described.

[0040] Figure 12 is a perspective view of the ink tank 6 in this embodiment, and Figure 13 is a magnified perspective view of the area around the ink inlet 17 in the ink tank 6. Figure 12(a) is an external perspective view of the ink tank 6, and Figure 12(b) is a perspective view of the ink tank 6 before the film 24 is welded to it. In this embodiment, the rib 18 has an opening 18b in the X direction and an opening 18a in the portion facing the ink holding member 20. The film 24 is welded to the end of the rib 18 that constitutes the opening 18b, and the opening 18b is closed. As a result, the rib 18 and the film 24 form an ink guide path 21.

[0041] If the ink tank 6 does not form an ink chamber by welding a thin film, the ink guide path 21 may be formed by bonding the member forming the side of the ink tank 6 to the opening 18b. In other words, if a member forms the side of the ink tank 6, the ink guide path 21 can be formed by bonding or welding a part of it to the opening 18b.

[0042] Thus, even if the portion of the rib 18 other than the opening 18a does not continuously surround the ink injection port 17, it is still possible to configure the ink guide path 21. The ink that flows into the ink guide path 21 is guided to the ink holding member 20 by the rib 18 and rib 26, as in the first embodiment, and is absorbed and held by the ink holding member 20.

[0043] In this embodiment, the film 24 is also welded to the ends of the ribs 19a and 19b in the X direction, which are formed on the outside of the rib 18, and the ink holding passage 25 is formed by the ribs 19a, 19b and the film 24. Even if the ink that has flowed into the ink guide passage 21 overflows in the +Y direction, the ink will flow into the ink holding passage 25 and be held there.

[0044] With the above configuration, the ink that flows into the ink guide path 21 is guided to and held in the ink holding member 20 or the ink holding path 25, thereby suppressing the widespread diffusion of ink. Furthermore, compared to the case where the entire area around the ink injection port 17 is surrounded by ribs 18, it is possible to reduce the width of the ink tank 6 in the X direction.

[0045] Furthermore, in this embodiment as well, the rib 18 may be extended so that the opening 18a contacts the ink holding member 20, similar to the first and second embodiments.

[0046] In this embodiment, the width of the ink tank 6 in the X direction is reduced, which reduces the dimensions of the ink holding member 20 in the X direction. However, the absorption capacity can be ensured by increasing the thickness of the ink holding member 20 in the Z direction.

[0047] In any embodiment, the ink guide path 21 may also have a finely textured surface, as shown in Figure 14, which is formed by arranging multiple cylinders 30 with diameters, heights, and pitches of several tens of micrometers. By making the surface of the ink guide path 21 a finely textured surface, the capillary force of the textured surface improves the wettability, making it easier to guide the ink. Furthermore, even if a finely textured surface is formed on the inside of the rib 18 (the side facing the outer surface 22 of the ink supply port 17), the ink adhering to the rib 18 will move more easily along the ink guide path 21 due to capillary force. In addition, the ink guide path 21 may be inclined downwards as it approaches the ink holding member 20 to facilitate the guidance of the ink to the ink holding member 20.

[0048] In all embodiments, the ink holding member 20 is provided at a position spaced apart from the ink injection port 17, allowing the ink holding member 20 to have a simple shape. For example, if the ink holding member 20 is provided so as to surround the ink injection port 17, the ink holding member 20 must be arranged around the ink injection port 17 in a shape that avoids the port, which can result in a complex shape. On the other hand, in the configurations of the first to third embodiments, the ink holding member 20 only needs to be positioned in the direction in which the ink is guided by the ink guide path 21, so it is not necessary to position the ink holding member 20 so as to surround the ink injection port 17. Therefore, the shape of the ink holding member 20 is not affected by the shape of the ink injection port 17, and it can be configured in a simple shape such as a rectangle.

[0049] In all embodiments, the ink holding member 20 has a shape in which the side surface in the Y direction is recessed inward. This prevents interference between the mating portion 104a and the ink holding member 20 when the housing 104 and the ink tank 6 are mated together as shown in Figure 6, allowing the housing 104 and the ink tank 6 to be mated together smoothly. Furthermore, in this embodiment, the ink holding member 20 has recesses on both sides of its side surface in the Y direction, making it symmetrical with respect to the X axis, which prevents interference with the mating portion 104a due to differences in the orientation of the ink holding member 20. However, the recesses of the ink holding member 20 only need to be provided at the mating location with the mating portion 104a, and do not need to be provided on both sides of the side surface in the Y direction.

[0050] Furthermore, in any embodiment, the opening 18a of the rib 18 and the opening 191a of the rib 19 do not necessarily have to be located behind the ink injection port 17 in the Y direction. For example, the openings of the ribs may be located in front of the ink injection port 17 in the Y direction, or the openings of the ribs may be located in other directions. In that case, the ink holding member 20 may be placed opposite the openings 18a and 191a, and the ink may be guided to the ink holding member 20 by the ink guide path 21. [Explanation of Symbols]
