  According to the printer 10 of the embodiment described above, the ink pack 310 can be brought into contact with the portion of the main body casing 20 covered by the upper casing 30 by opening and closing the upper casing 30. The degree of freedom of the position to arrange can be improved. Further, since the upper housing 30 is pivotally attached to the main body housing 20 so as to be openable and closable above the printing mechanism unit 50, the upper housing 30 that houses the ink pack 310 is used as a cover for the printing mechanism unit 50. At the same time, by opening and closing the upper housing 30, the printing mechanism unit 50 accommodated in the main body housing 20 can be easily maintained.

  In addition, since each of the ink packs 310 is placed on the inclined plate 381 of the holder 380, the weight of the ink packs 310 extends to the adjacent ink packs 310 while efficiently storing a plurality of ink packs 310. It is possible to prevent this from happening. Further, since the ink pack 310 is held from below through the closed state of the upper housing 30 from the closed state, the ink pack 310 can be prevented from being excessively pressed against the adjacent holder 380 by its own weight.

  Further, by providing the holder auxiliary rib 364 in the lower housing 360, the holder 380 can be reinforced against the force in the direction in which the inclined plate 381 is inclined. Further, by suspending the end auxiliary ribs 374 on the upper housing 370, the ink pack 310 placed on the holder 380 located at the end opposite to the side where the inclined plate 381 is inclined is excessively deformed. Can be suppressed. Further, by suspending the intermediate auxiliary rib 376 on the upper housing 370, it is possible to prevent the upper portion of the ink pack 310 that is not supported by the back surface of the inclined plate 381 of the adjacent holder from being deformed excessively. In addition, since the upper end portion 383 of the inclined plate 381 in the holder 380 is engaged with the engaging portion 373 provided in the upper housing 370, it is possible to suppress the holder 380 from being deformed excessively.

FIG. 14 is an explanatory diagram illustrating a configuration around the printing mechanism unit 50 of the printer 10 according to another embodiment.

  As shown in FIGS. 12, 13, and 14, the supply tube 340 connects the ink supply unit 330 and the carriage 80 of the printing mechanism unit 50, and supplies the ink in the ink pack 310 to the carriage 80. The supply tube 340 extends from the ink supply unit 330 in the direction of the rotation axis 350 substantially horizontally (when the upper housing 30 is closed) (hereinafter referred to as “first horizontal part H1”), and from the first horizontal part H1. A portion (hereinafter referred to as “second horizontal portion H2”) located in a substantially horizontal plane below and extending in a direction substantially orthogonal to the rotation shaft 350, and a portion substantially parallel to the rotation shaft 350 (hereinafter referred to as “third horizontal portion”). H3 ”) are connected in sequence.

  FIG. 15 is an explanatory view showing a cross section of the supply tube 340. FIG. 15A shows a cross section (S1-S1 cross section in FIG. 14) perpendicular to the ink flow direction of the supply tube 340 in the second horizontal portion H2, and FIG. 15B shows the third horizontal portion H3. 14 shows a cross section (S2-S2 cross section in FIG. 14) perpendicular to the ink distribution direction of the supply tube 340. As shown in FIGS. 15A and 15B, the supply tube 340 is provided with four hollow ink flow paths 342 corresponding to the four ink packs 310. As shown in FIG. 15A, in the second horizontal portion H2, the direction of the supply tube 340 around the ink flow direction is such that the four ink flow paths 342 are arranged substantially horizontally (hereinafter referred to as “horizontal”). It is also called “arrangement”. The direction of the supply tube 340 in the first horizontal portion H1 is the same. On the other hand, as shown in FIG. 15B, in the third horizontal portion H3, the direction of the supply tube 340 around the ink distribution direction is such that the four ink flow paths 342 are arranged substantially vertically (hereinafter referred to as “vertical”). It is also called “arrangement”.

  Between the first horizontal portion H1 and the second horizontal portion H2 of the supply tube 340 (in the vicinity of the rotation shaft 350), a portion curved along a vertical semicircular arc (hereinafter referred to as “first curved portion R1”). Is provided. The first horizontal portion H1 and the second horizontal portion H2 are both laterally arranged, and the first curved portion R1 does not have a twist. In addition, a portion curved along a horizontal semicircular arc (hereinafter referred to as “second curved portion R2”) is provided between the second horizontal portion H2 and the third horizontal portion H3. Since the second horizontal portion H2 is laterally arranged, and the third horizontal portion H3 is vertically arranged, the second curved portion R2 has a twist of about 90 degrees. Further, a portion curved along a horizontal semicircular arc (hereinafter referred to as “third curved portion R3”) is provided between the third horizontal portion H3 and the carriage 80.

  As shown in FIGS. 12 and 13, the supply tube 340 follows the operation of opening the upper housing 30 by the deformation of the first bending portion R <b> 1 provided near the rotation shaft 350. Therefore, even in the printer 10 in which the ink supply unit 330 and the printing mechanism unit 50 are connected by the relatively long supply tube 340, the presence of the supply tube 340 is prevented from obstructing the opening and closing of the upper housing 30. .

  The supply tube 340 may have a joint 410 as shown in FIGS. 12 and 13. And the part by the side of the printing mechanism part 50 rather than the coupling 410 of the supply tube 340 is good also as being formed with a comparatively highly flexible material (for example, polyethylene-type elastomer). In this way, it is possible to easily form a non-linear portion such as the first curved portion R1 of the supply tube 340, and it is possible to give the first curved portion R1 good flexibility. In addition, the portion of the supply tube 340 closer to the ink supply unit 330 than the joint 410 may be formed of a material with relatively low flexibility (for example, polypropylene).

  The supply tube 340 is supported by support portions 420 and 430 disposed at two positions across the second bending portion R2. The support parts 420 and 430 are fixed to the main body housing 20 of the printer 10 directly or indirectly. Therefore, the supply tube 340 is supported by the printer 10 main body via the support portions 420 and 430.

  FIG. 16 is an explanatory diagram illustrating a configuration of a support portion 420 according to another embodiment. 16A shows an upper plane of the support portion 420, and FIG. 16B shows a cross section perpendicular to the ink flow direction of the support portion 420 (S3-S3 cross section in FIG. 16A). ing. As shown in FIG. 16B, the support portion 420 includes a long side member 422 arranged in the horizontal direction, a short side member 424 protruding upward from both ends of the cross section of the long side member 422, and the short side member 424. And a floating prevention portion 426 protruding in the horizontal direction from the upper end of the cross section toward the inside. As shown in FIG. 16A, two floating prevention portions 426 are provided for each short side member 424, and the positions along the ink flow direction are the floating portions provided on the two short side members 424. The prevention portions 426 are set alternately so as not to be in the same position. The long side member 422, the short side member 424, and the anti-floating portion 426 form a space having a substantially rectangular cross-sectional shape that houses the supply tube 340, and the supply tube 340 is stored in the space. At this time, the floating prevention unit 426 prevents the supply tube 340 from floating and coming off.

  The support portion 420 further includes a positioning member 428 adjacent to the space side of the short side member 424. In the example of FIG. 16, three sets of positioning members 428 are provided, and the positioning members 428 of each set are arranged at positions facing each other across the supply tube 340. Therefore, the positioning member 428 reduces the internal dimension between the two short side members 424. By the positioning member 428, the supply tube 340 is pressed in the long side direction, and the movement of the supply tube 340 along the ink circulation direction is suppressed. Therefore, the supply tube 340 is prevented from interfering with other parts of the printer 10.

  As shown in FIG. 15, the cross section of the ink flow path 342 of the supply tube 340 is not circular, but has an oval shape that is long in the direction in which the ink flow paths 342 are arranged (the left-right direction in FIG. 15A). . For example, in order to make the supply tube 340 bend easily in the first bending portion R1 and the second bending portion R2 (see FIG. 14), the cross section of the supply tube 340 has a shape in which an ellipse is combined. This is to keep the height small. Here, as shown in FIG. 16B, at the position where the positioning member 428 of the support portion 420 is provided, the supply tube 340 is pushed from the positioning members 428 on both sides, so that the cross section of the ink flow path 342 is circular. And the cross-sectional area of the ink flow path 342 increases. Accordingly, the flow path resistance in the supply tube 340 can be reduced by the positioning member 428 of the support portion 420.

  The configuration of the support portion 430 (see FIG. 14) is the same as the configuration of the support portion 420 shown in FIG. 16, but the support portion 430 can be prevented from moving the supply tube 340 by the support portion 420. The positioning member 428 may not be provided. Further, the direction in which the support part 430 is disposed is the direction in which the support part 420 is rotated by approximately 90 degrees in accordance with the direction of the supply tube 340.

  In addition, since the support parts 420 and 430 are arrange | positioned on both sides of 2nd curved part R2 which has a twist and is easy to generate | occur | produce position shift, it can support the supply tube 340 stably. .
