<Configuration of external tank unit>
Next, details of the configuration of the external tank unit 20 will be described.
FIG. 2 is a perspective view showing how the ink tank cartridge 30 is mounted. In FIG. 2, the three cartridge storage cases 40 in which the ink tank cartridges 30 are installed are already attached to the holder 50. Further, the remaining one cartridge storage case 40 in which the ink tank cartridge 30 is installed is in the middle of mounting.

  When installing the ink tank cartridge 30 in the external tank unit 20, the user first holds the ink tank cartridge 30 and moves the ink tank cartridge 30 in the vertical direction (−Z direction, gravity direction) from the top to the bottom. It is installed in the cartridge housing case 40. Thereafter, the user holds the cartridge housing case 40 in which the ink tank cartridge 30 is installed, and this time moves the cartridge housing case 40 in the lateral direction of the arrow R (the + X direction, the direction intersecting the gravity direction). To the holder 50. At this time, by having the grip portion 41 provided in the cartridge housing case 40, the cartridge housing case 40 can be easily mounted on the holder 50 by sliding in the lateral direction.

  On the other hand, when taking out the ink tank cartridge 30 from the external tank unit 20 in order to replace the ink tank cartridge 30, the user holds the grip portion 41 of the cartridge housing case 40 in which the ink tank cartridge 30 is installed, This time, the cartridge housing case 40 is moved in the direction opposite to the arrow R (−X direction) and taken out from the holder 50. Also in this case, the user can easily take out the cartridge housing case 40 from the holder 50 by sliding the cartridge housing case 40 in the lateral direction by having the grip portion 41.

FIG. 3 shows a view of the ink tank cartridge 30 as viewed from below, and FIG. 4 shows a view of the inside of the ink tank cartridge 30 as viewed from below. As shown in FIG. 3, the cartridge case 31 of the ink tank cartridge 30 is configured by a rectangular box-like cardboard. When the user uses the ink tank cartridge 30 for the first time, the opening 31p of the cartridge case 31 is peeled off, and openings are formed on the side surface 31a (+ X direction side) and the bottom surface 31b (−Z direction side) of the cartridge case 31. Used after forming.
The material of the cartridge case 31 is not limited to corrugated cardboard, and may be cardboard or resin, for example.

  As shown in FIG. 4, an ink having a bag-shaped ink pack 32 filled with ink, a connection member 33, and an L-shaped ink supply port pipe 36 is provided in the cartridge case 31 of the ink tank cartridge 30. A supply port member (supply port member) 35 is accommodated. The ink pack 32 is protected in the cartridge case 31 by a cardboard 32a (a part is shown in the figure). An ink supply port member 35 for supplying ink in the ink pack 32 to the printer 1 side is joined to the ink pack 32 by heat welding.

  The ink supply port member 35 has a supply port 37 for communicating with the inside of the ink pack 32 from the outside, and a pair of positioning holes 38. The position of the ink supply port member 35 in the cartridge case 31 is fixed by being partially fitted into a notch 33 a formed in the connection member 33. The connection member 33 also serves as a buffer member that supports the weight of the ink pack 32 in the cartridge case 31. In addition, an opening 33 b is formed at the + X direction end of the connection member 33. The opening 33b is connected to the opening (see FIG. 3) on the side surface 31a after the opening 31p of the cartridge case 31 is peeled off. Accordingly, the supply port 37 of the ink supply port member 35 is opened to the outside through the opening 33 b of the connection member 33 and the opening of the side surface 31 a of the cartridge case 31.

  FIG. 5 is a perspective view for explaining the configuration of the holder 50. As shown in FIG. 5, the holder 50 includes a side wall 50a and side walls 50b (both sides in the Y-axis direction), a back wall 50c (+ X direction side), a bottom wall 50d (−Z direction side), and three partition walls 50e. Thus, four sub-holders 51 are provided. Each sub-holder 51 is mounted with each cartridge housing case 40 in which the ink tank cartridge 30 is installed.

  Each sub-holder 51 is provided with a protrusion 55 that contacts the back wall 50c and protrudes from the bottom wall 50d to the + Z direction side or the −X direction side. An ink supply pipe 56 and a pair of positioning rods 57 projecting to the front side are provided on the front side (−X direction side) of the protrusion 55. The positions of the ink supply pipe 56 and the positioning rod 57 are lower than the position of the surface on the upper side (Z direction side) of the protrusion 55. The ink supply pipe 56 is connected to the corresponding tube 21 communicating from the sub tank unit 17. When the user slides the cartridge housing case 40 in which the ink tank cartridge 30 is installed in the lateral direction and attaches it to the sub holder 51, the ink supply pipe 56 is connected to the ink supply port member 35 provided in the ink tank cartridge 30. The ink in the ink pack 32 is inserted into the supply port 37 and supplied to the sub tank unit 17 through the tube 21. The pair of positioning rods 57 are inserted into the positioning holes 38 of the ink supply port member 35, thereby fixing the mounting position of the cartridge housing case 40.

  Concave portions 58 serving as guide grooves are formed along the X-axis direction on the inner wall surfaces (the surfaces of the side walls 50a and 50b and the surface of the partition wall 50e) on both sides in the Y-axis direction of each sub-holder 51. FIG. 6 is a perspective view showing a state in which the cartridge housing case 40 is mounted on the sub-holder 51. In FIG. 6, the ink tank cartridge 30 installed in the cartridge housing case 40 is omitted. On the outer wall surface (surface of the side walls 40a and 40b) of the cartridge housing case 40, a convex portion 42 is formed along the X-axis direction at a position corresponding to the concave portion 58 of each sub-holder 51. When the user attaches the cartridge housing case 40 to the sub-holder 51, the convex portion 42 of the cartridge housing case 40 is fitted into the concave portion 58 of the sub-holder 51, and the position of the convex portion 42 is subsequently restricted by the concave portion 58. However, it is mounted to the back (+ X direction side) of the sub-holder 51.

  Here, when the user erroneously tries to attach the cartridge storage case 40 to the sub holder 51 from the top of the sub holder 51 in the vertical direction (−Z direction) instead of in the horizontal direction, the following occurs. The convex portion 42 of the cartridge housing case 40 comes into contact with the upper surfaces of the walls (side walls 50a and 50b and the partition wall 50e) on both sides in the Y-axis direction of the sub holder 51, and the user places the cartridge housing case 40 below the contact portion ( -Z direction side) cannot be moved. Even if the cartridge housing case 40 can be moved downward (−Z direction side) from the contact location, the bottom surface of the cartridge housing case 40 comes into contact with the upper surface of the protrusion 55 provided on the sub-holder 51. The user cannot move the cartridge housing case 40 below the contact portion. As a result, when the user misplaces the cartridge housing case 40 with respect to the sub-holder 51, the cartridge housing case 40 contacts the ink supply tube 56 of the sub-holder 51, and the ink supply tube 56 is damaged. Can be prevented.

  Note that a convex portion may be formed on the inner wall surface of each sub-holder 51 instead of the concave portion 58, and a concave portion may be formed on the outer wall surface of the cartridge housing case 40 instead of the convex portion 42. In this case, when the cartridge storage case 40 is to be mounted in the sub-holder 51 in the vertical direction, the bottom of the cartridge storage case 40 comes into contact with the convex portion of the sub-holder 51, and the user moves the cartridge storage case 40 from the contact position. It cannot be moved downward.

  FIG. 7 is an explanatory view showing a state where the ink supply pipe 56 of the holder 50 is inserted into the ink supply port member 35 of the ink tank cartridge 30. In FIG. 7, in order to facilitate the explanation, members necessary for the explanation are mainly described. When the user completely attaches the cartridge housing case 40 in which the ink tank cartridge 30 is installed to the holder 50, the ink supply pipe 56 of the holder 50 is connected to the ink pack 32 as shown in FIG. The ink supply port tube 36 is inserted from the supply port 37 of the port member 35. A check valve (not shown) is provided in a tube extending in the Z-axis direction of the L-shaped ink supply port tube 36. When the ink in the ink pack 32 flows to the sub tank unit 17 through the ink supply port pipe 36 and the tube 21, the check valve is opened. On the other hand, when the ink does not flow to the sub tank unit 17, the check valve is closed to prevent air from the outside from entering the ink pack 32.

  In the embodiment described above, the user moves the ink tank cartridge 30 in the vertical direction and installs the ink tank cartridge 30 in the cartridge storage case 40, and then moves the cartridge storage case 40 in the horizontal direction and attaches it to the holder 50. At this time, since the shape of the ink supply port tube 36 is L-shaped, the ink supply tube 56 can be inserted into the ink supply port tube 36 in the lateral direction, and the ink in the ink pack 32 is transferred to the ink supply tube 56. To the printer 1 side.

  Further, in comparison with the conventional configuration in which the ink tank cartridge is moved in the vertical direction and the ink supply pipe of the holder is inserted into the ink supply port pipe, the cartridge housing case 40 is moved in the horizontal direction and is attached to the holder 50. In the configuration of the embodiment, the ink supply pipe 56 can be easily and reliably inserted into the ink supply port pipe 36. Further, it is possible to avoid breakage of the ink supply tube when the ink tank cartridge is moved in the vertical direction and the ink supply tube is inserted into the ink supply port tube. Furthermore, it is possible to prevent the trouble that the user lifts the ink tank cartridge from the holder and pulls out the ink supply port tube from the ink supply tube during printing, and bubbles enter the printer side from the ink supply tube. Furthermore, even when the ink capacity increases, the user does not need to lift the ink tank cartridge vertically upward.

(Modification 1)
In the embodiment described above, the ink tank cartridge 30 is provided with the L-shaped ink supply port tube 36, but the shape of the ink supply port tube 36 is not limited to the L shape. The ink supply tube 56 of the holder 50 can be inserted into the ink supply port tube 36 by moving the cartridge housing case 40 in the lateral direction, and the ink in the ink tank cartridge 30 can be supplied to the printer 1 side. If so, the ink supply port tube 36 may have any shape.

(Modification 2)
In the above-described embodiment, the user holds the ink tank cartridge 30 in the vertical direction by moving the ink tank cartridge 30 in the hand and installs it in the cartridge storage case 40, and then moves the holder 50 in the horizontal direction by holding the cartridge storage case 40 in the hand. It is attached to. However, a configuration may be adopted in which these operations are not manually performed by the user, but all or a part of these operations are automatically performed by, for example, a mechanical device or the like.
