Hereinafter, a multifunction peripheral including an ink jet printer (hereinafter abbreviated as “printer”), which is a kind of recording apparatus, will be described with reference to the drawings.
(First embodiment)
As illustrated in FIG. 1, the multifunction machine 11 includes a printer 12 that performs recording on a sheet P that is an example of a medium, and a scanner 13 that is provided in the upper part of the printer 12 in the vertical direction Z. The scanner 13 is provided so as to be able to read an image recorded on a document placed on the placing table 14. The printer 12 includes a rectangular parallelepiped housing 16 having an opening 15 formed therein, and images such as characters and photographs are ejected into the housing 16 by ejecting ink, which is an example of liquid, onto the paper P. A recording unit 17 is provided for recording the above. In addition, let the side in which the opening part 15 is formed in the housing | casing 16 be the front side of the printer 12, and let the opposite side be a back side.

  The recording unit 17 includes a carriage 18 that can reciprocate along a scanning direction X that coincides with the longitudinal direction of the casing 16, and a recording head 19 that is attached to the lower surface of the carriage 18 in the vertical direction Z. That is, the recording unit 17 performs recording over substantially the entire area of the paper P in the scanning direction X by moving the recording head 19 that ejects ink onto the paper P along the scanning direction X by the carriage 18. Do.

  In the housing 16, a paper cassette 20 placed in a state where the paper P is stacked is provided below the opening 15 so that the paper cassette 20 can be inserted into and removed from the housing 16. The opening 15 is provided with a discharge tray 21 that can be pulled out from the opening 15 toward the front of the printer 12. That is, the printer 12 conveys the paper P placed on the paper cassette 20 one by one from the back to the front of the printer 12, and after the recording unit 17 records an image on the paper P, the paper P is directed to the discharge tray 21. Then, the paper P is discharged out of the housing 16 from the opening 15. Here, the transport direction Y in which the paper P is transported coincides with the direction from the back surface to the front surface of the printer 12 and intersects the scanning direction X, which is the moving direction of the carriage 18. In the multifunction machine 11, an operation unit 22 used to operate the scanner 13 and the printer 12 is provided at a position above the opening 15 so as to protrude forward.

  As shown in FIGS. 1 and 2, in one side of the printer 12 in the scanning direction X (the right side in FIGS. 1 and 2), the liquid storage that stores the ink that the recording unit 17 discharges to the paper P is stored. A liquid container mounting part 30 to which the body 40 is mounted is attached. A plurality of liquid containers 40 are mounted on the liquid container mounting part 30 along the transport direction Y, and inks of different colors are stored in the liquid containers 40, respectively. In the present embodiment, four liquid containers 40 are mounted on the liquid container mounting part 30, and the liquid container 40 located on the most downstream side in the transport direction Y has a larger capacity than the other three. Has become. These four liquid containers 40 contain, for example, four colors of ink of cyan, magenta, yellow, and black, and have a large capacity liquid container 40 that is located on the most downstream side in the transport direction Y. Contains black ink which is frequently used.

  Further, the liquid container mounting part 30 is formed with a window part 31 for confirming the remaining amount of ink stored in the liquid container 40. That is, the liquid container 40 constitutes one surface of the liquid container 40, and the liquid container 40 is configured such that the visual recognition surface 41 that can visually recognize the remaining amount of ink stored in the liquid container 40 is exposed from the window portion 31. It is attached to the attachment part 30. A supply tube 23 through which ink flows is connected to the liquid container 40 mounted on the liquid container mounting part 30 in this way. The supply tube 23 has one end connected to the liquid container 40 and the other end connected to the recording unit 17. In other words, the ink stored in the liquid container 40 is supplied to the recording head 19 by the supply tube 23 extending from the liquid container mounting portion 30 through the housing 16. One supply tube 23 is connected to each liquid container 40, but only one supply tube 23 is shown in FIG. 1 for simplification of the drawing.

  As shown in FIG. 2, an opening / closing cover 32 that can be opened and closed vertically is provided on the upper part of the liquid container mounting portion 30 in the vertical direction Z. When the opening / closing cover 32 is opened, the inlet 42 of the liquid container 40 attached to the liquid container attachment part 30 is exposed. The inlet 42 has a cylindrical portion 43 that protrudes in a cylindrical shape upward from the top of the liquid container 40 in the vertical direction Z, and opens in a circular shape at the upper end of the cylindrical portion 43. And a communication port 44 that communicates with each other. The injection port 42 is provided for injecting ink into the liquid container 40.

  A cylindrical blocking member 45 that closes the communication port 44 is detachably provided at the injection port 42. The closing member 45 is a bottomed cap member whose lower part is opened, and has a diameter larger than that of the cylindrical portion 43. The closing member 45 is attached to the injection port 42 so as to cover the cylindrical portion 43 from above. In addition, on the upper part of the liquid container mounting portion 30 exposed by opening the opening / closing cover 32, a mounting portion 33 on which the closing member 45 removed from the inlet 42 can be mounted is formed.

  As shown in FIG. 3, the liquid container 40 is a resin container having a box shape, and is configured as a so-called ink tank that stores ink therein. That is, a liquid storage chamber 46 for storing ink is provided inside the liquid storage body 40. The liquid storage chamber 46 is communicated with the outside of the liquid container 40 by a communication port 44 formed in a cylindrical portion 43 constituting an injection port 42 provided in the upper part of the liquid container 40 in the vertical direction Z. ing. When the ink is injected into the liquid storage chamber 46, the ink is injected through the communication port 44.

  A plurality of plate-like rib members 47 are provided in the liquid storage chamber 46. The ink stored in the liquid storage chamber 46 flows along the rib member 47 when supplied from the liquid storage chamber 46 to the recording unit 17, so that the retention of ink in the liquid storage chamber 46 is suppressed. . The viewing surface 41 (the left surface in FIG. 3) of the liquid container 40 is formed of a transparent or translucent resin so that the remaining amount of ink stored in the liquid storage chamber 46 can be viewed. An upper limit scale 48 indicating the upper limit amount of ink that can be stored in the liquid storage chamber 46 is formed on the viewing surface 41.

  Further, in the vertical direction Z, an air communication hole 49 is formed at a position different from the inlet 42 in the upper part of the liquid container 40. The air communication hole 49 communicates with the first air chamber 50 provided in the liquid container 40. The first air chamber 50 communicates with one end of a meandering path 51 similarly provided in the liquid container 40, and the other end of the meandering path 51 is a second air chamber provided in the liquid container 40. Communicate with 52. Further, the second air chamber 52 communicates with the liquid storage chamber 46. That is, the atmosphere communication hole 49, the first air chamber 50, the meandering path 51, and the second air chamber 52 communicate with the inside of the liquid storage chamber 46 and the outside of the liquid storage chamber 46 (the atmosphere outside the liquid storage body 40). It functions as a communication path 53. The atmosphere communication path 53 suppresses the inside of the liquid storage chamber 46 from becoming negative pressure as the ink stored in the liquid storage chamber 46 is supplied to the recording unit 17. If the pressure in the liquid storage chamber 46 becomes negative, the supply of ink to the recording unit 17 may be delayed. However, if there is a configuration in which the liquid storage chamber 46 communicates with the atmosphere, such a risk is eliminated. In FIG. 3, a sheet member (not shown) is attached to one surface of the liquid container 40 where the inside of the liquid storage chamber 46 and the inside of the atmosphere communication path 53 are exposed by thermocompression bonding.

  As shown in FIG. 4, in the vertical direction Z, a male screw 54 is formed on the outer peripheral surface of the cylindrical portion 43 that protrudes upward from the upper portion of the liquid container 40, while the plug 42 closes the inlet 42. A female screw 55 that can be screwed with the male screw 54 is formed on the inner peripheral surface of the member 45. The male screw 54 and the female screw 55 are spirally formed along the peripheral surfaces of the cylindrical portion 43 and the closing member 45, respectively. That is, when the male screw 54 and the female screw 55 are screwed together, the closing member 45 is mounted in a state of being fastened to the inlet 42. In the present embodiment, when the liquid container 40 is viewed from above, the closing member 45 is attached to the injection port 42 by rotating in the clockwise direction, and is injected into the injection port 42 by rotating in the counterclockwise direction. An external thread 54 and an internal thread 55 are formed so as to be removed from the internal thread. In addition, the screwing here refers to that each other is coupled by the action of a general screw.

  Further, a sealing member 56 made of, for example, an O-ring made of rubber is provided on the inner bottom surface of the closing member 45 that faces the communication port 44 in the vertical direction Z when mounted on the injection port 42. The closing member 45 is configured to seal the injection port 42 with a sealing member 56 in a state where it is attached to the injection port 42. That is, in a state where the closing member 45 is attached to the injection port 42, the sealing member 56 is located between the closing member 45 and the injection port 42, and is located between the inner bottom surface of the closing member 45 and the tip of the cylindrical portion 43. The inlet 42 is sealed by close contact.

Next, the operation of the multi-function device 11 configured as described above will be described with particular attention to the closing member 45 attached to the liquid container 40.
As shown in FIG. 4, the closing member 45 is attached to the injection port 42 by the male screw 54 formed on the cylindrical portion 43 and the female screw 55 formed on the closing member 45 being screwed together to close the injection port 42. doing. Here, for example, the temperature and atmospheric pressure around the liquid container 40 change depending on the transportation of the multifunction machine 11 and the usage environment of the multifunction machine 11, and the outside of the liquid container 40 is more external than the atmospheric pressure in the liquid container chamber 46. The atmospheric pressure may be low. If the air pressure in the liquid storage chamber 46 becomes higher than the air pressure outside the liquid storage chamber 46, it is conceivable that a force directed from the inside of the liquid storage chamber 46 to the outside is generated due to the pressure difference.

  Normally, as shown in the present embodiment, an air communication path 53 that connects the liquid storage chamber 46 and the atmosphere is formed in the liquid container 40 that stores the ink. Since it is provided in order to eliminate the negative pressure in the liquid storage chamber 46 that occurs during supply, the flow resistance is high, and it may not be possible to cope with sudden changes in atmospheric pressure. In addition, when the multifunction machine 11 is shipped, the atmosphere communication hole 49 may be sealed with a sheet member, and the atmosphere communication path 53 may be used while being blocked. Further, in order to prevent the ink stored in the liquid storage chamber 46 from leaking out through the atmosphere communication path 53 due to vibrations when carrying the multifunction machine 11, a configuration is provided in which a cap for closing the atmosphere communication hole 49 is separately provided. Is also known. Therefore, a situation in which the air pressure inside the liquid storage chamber 46 becomes higher than the air pressure outside the liquid container 40 may occur sufficiently.

  Here, when the closing member 45 attached to the inlet 42 of the liquid container 40 is a plug member that is formed of an elastic member such as an elastomer and is attached by being press-fitted into the inlet 42, There is a possibility that the closing member 45 is pushed out of the injection port 42 due to a pressure difference between the inside and outside of the liquid storage chamber 46 and unexpectedly falls off. In this respect, in this embodiment, since the male member 54 and the female screw 55 are screwed together, the closing member 45 is mounted in a state of being fastened to the inlet 42, so that the inside and outside of the liquid storage chamber 46 Even if an atmospheric pressure difference occurs, the possibility that the closing member 45 drops off from the inlet 42 is reduced.

According to the first embodiment, the following effects can be obtained.
(1) When the female screw 55 formed on the closing member 45 and the male screw 54 formed on the cylindrical portion 43 of the injection port 42 are screwed together, the closing member 45 is mounted in a state of being fastened to the injection port 42. The That is, even if the air pressure in the liquid storage chamber 46 that is inside the liquid container 40 is higher than the air pressure outside the liquid container 40, the closing member 45 is mounted in a state of being fastened to the inlet 42. Therefore, the possibility that the closing member 45 is dropped from the inlet 42 due to the pressure difference is reduced. Accordingly, it is possible to suppress the dropout of the closing member 45 that blocks the liquid inlet 42 provided in the liquid container 40 that stores the liquid.

(2) From the sealing member 56 provided on the inner bottom surface of the closing member 45, ink leakage from the injection port 42 can be reduced in a state where the closing member 45 is attached to the injection port 42.
(3) The remaining amount of ink stored in the liquid storage chamber 46 can be confirmed by the visual recognition surface 41 constituting one surface of the liquid storage body 40.

  (4) The upper limit scale 48 formed on the visual recognition surface 41 constituting the liquid container 40 can confirm the upper limit of the ink that can be stored in the liquid storage chamber 46. Therefore, when ink is injected into the liquid storage chamber 46 through the injection port 42, it is possible to prevent the ink from overflowing from the injection port 42 due to excessive ink insertion.

  (5) Due to the mounting portion 33 formed in the liquid container mounting portion 30, it is not necessary to place the closing member 45 removed from the injection port 42 on a floor surface or a desk. For this reason, the risk of smearing the periphery of the multifunction machine 11 with ink droplets adhering to the closing member 45 is reduced.

(Second embodiment)
Next, a second embodiment of the printer 12 included in the multifunction machine 11 will be described. The printer 12 in the second embodiment is different from the first embodiment in the configuration of the liquid container mounting portion 30 and the closing member 45 attached to the liquid container 40, and other configurations are the same as those in the first embodiment. It is the same. Therefore, the description of the portions having the same configuration is omitted.

  As shown in FIGS. 5 and 6, a closing member 45 is detachably provided at the inlet 42 of the liquid container 40 mounted on the liquid container mounting part 30. In the vertical direction Z, a columnar protrusion 60 extending upward is formed on the upper surface of the closing member 45. A large-diameter portion 61 is provided at the distal end portion of the protruding portion 60 so as to have a larger diameter than the proximal end portion in contact with the upper surface of the closing member 45. A holding member 62 that connects the closing member 45 and the liquid container mounting portion 30 is attached to the protrusion 60. The holding member 62 is a strip-like long member having a predetermined length in one direction, and one end in the length direction is attached to the protrusion 60, while the other end is opposite to the one end. Is attached to the upper part of the liquid container mounting part 30. Therefore, the closing member 45 removed from the inlet 42 is held by the holding member 62 so as to be suspended from the liquid container mounting portion 30. Note that the predetermined length of the holding member 62 means that the closing member 45 attached to the injection port 42 of one liquid container 40 has a liquid container 40 different from the one liquid container 40. The length does not reach the entrance 42.

  In addition, a ring portion 63 formed in an annular shape is provided at one end portion of the holding member 62 attached to the protruding portion 60. The holding member 62 is attached to the protruding portion 60 so as to be relatively rotatable by attaching the ring portion 63 with the portion having a smaller diameter on the proximal end side than the large diameter portion 61 of the protruding portion 60 as an axis. . That is, the holding member 62 is provided to be rotatable relative to the closing member 45. Further, since the inner diameter of the ring portion 63 is formed to be smaller than the diameter of the large diameter portion 61 formed at the tip of the projection portion 60, the possibility that the holding member 62 will fall off the projection portion 60 is reduced. Yes. The holding member 62 is made of an elastic material such as a resin, and the ring portion 63 moves over the large-diameter portion 61 while elastically deforming in the direction in which the inner diameter expands, so that the shaft on the proximal end side of the protruding portion 60 It is attached.

Next, the operation of the multi-function device 11 configured as described above will be described with particular attention to the closing member 45 attached to the liquid container 40.
When injecting ink into the liquid container 40, when the liquid container 40 is viewed from above, the closing member 45 attached to the injection port 42 of the liquid container 40 is turned counterclockwise. The blocking member 45 is removed from the inlet 42. Further, when the ink injection into the liquid container 40 is completed, the closing member 45 attached so as to cover the injection port 42 from above is rotated in the clockwise direction so that the closing member 45 is attached to the injection port 42. To do. At this time, the holding member 62 that holds the closing member 45 is attached to the protrusion 60 formed on the closing member 45 so as to be relatively rotatable, and therefore when the closing member 45 is attached to and detached from the inlet 42. There is little possibility that the holding member 62 is twisted with the rotation operation.

According to the second embodiment, in addition to the effects (1) to (5), the following effects can be obtained.
(6) Since the closing member 45 and the liquid container mounting portion 30 are connected by the holding member 62, the possibility of losing the closing member 45 removed from the inlet 42 is reduced.

  (7) It is possible to reduce the possibility that the holding member 62 is twisted with the rotation of the closing member 45 when the closing member 45 is attached to and detached from the injection port 42. That is, it is possible to reduce the possibility of hindering the attaching / detaching operation of the closing member 45 to the injection port 42. In addition, since the possibility that the holding member 62 is twisted is small, it is possible to contribute to extending the life of the holding member 62.

  (8) With the holding member 62 having a predetermined length, for example, the closing member 45 that closes the injection port 42 of the liquid container 40 that stores black ink erroneously stores other color ink such as yellow. Thus, the detachment of the closing member 45 such as being attached to the inlet 42 of the liquid container 40 is suppressed. That is, it is possible to reduce the possibility that ink different from the ink stored in the liquid container 40 is mixed into the liquid container 40 via the closing member 45.

(Third embodiment)
Next, a third embodiment of the printer 12 included in the multifunction machine 11 will be described. The printer 12 in the third embodiment is different from the second embodiment in the configuration of the closing member 45 and the holding member 62 attached to the closing member 45, and the other configurations are the same as those in the second embodiment. Therefore, the description of the portions having the same configuration is omitted.

  As shown in FIG. 7, in the vertical direction Z, the upper surface of the closing member 45 is provided with a columnar protrusion 70 that protrudes upward. A holding member 71 that connects the closing member 45 and the liquid container mounting portion 30 is attached to the protrusion 70. The holding member 71 is a strip-like long member having a predetermined length in one direction, and one end in the length direction is attached to the tip of the protruding portion 70, and is opposite to the one end. The other end is attached to the upper part of the liquid container mounting part 30. Therefore, the closing member 45 removed from the inlet 42 is held by the holding member 71 so as to be suspended from the liquid container mounting portion 30. Note that the predetermined length of the holding member 71 means that the closing member 45 attached to the injection port 42 of one liquid container 40 has a liquid container 40 different from the one liquid container 40. The length does not reach the entrance 42.

  In addition, one end portion of the holding member 71 attached to the tip of the projection 70 is configured as a cap-like attachment 72 that is fitted to the tip of the projection 70 so as to be relatively rotatable from above. That is, the holding member 71 is provided to be rotatable relative to the closing member 45. And the holding member 71 which is this strip-shaped elongate member can be wound around the projection part 70 of the closure member 45 by rotating the attachment part 72 of the one end and the projection part 70 of the closure member 45 relatively. Is provided.

Next, the operation of the multi-function device 11 configured as described above will be described with particular attention to the closing member 45 attached to the liquid container 40.
As shown in FIG. 7, when the closing member 45 is attached to and detached from the inlet 42 of the liquid container 40, the closing member 45 is rotated with respect to the inlet 42. At this time, since the holding member 71 is attached to the closing member 45 so as to be rotatable relative to the closing member 45, the holding member 71 is less likely to be twisted with the rotation of the closing member 45. Further, when the blocking member 45 removed from the injection port 42 is placed on the placement portion 33, the holding member 71 is rotated by rotating the attachment portion 72 of the holding member 71 with respect to the protrusion 70. Wrapped around. The same applies to the closing member 45 attached to the injection port 42, and the holding member 71 is wound around the protruding portion 70 by rotating the mounting portion 72 relative to the protruding portion 70 in that state.

According to the third embodiment, in addition to the effects (1) to (8), the following effects can be obtained.
(9) Since the holding member 71 having a predetermined length can be wound around the protruding portion 70 when the closing member 45 is mounted on the injection port 42 and placed on the placement portion 33, the holding member 71 Can contribute to compactness.
