■■■ About platen, waste ink cartridge, ink absorber ■■■■■■■
The configuration and arrangement of the platen 44, the waste ink cartridge 68, and the ink absorber 60 will be described with reference to FIGS.
First, as shown in FIG. 4, the carriage 40 is configured to be movable between an end on the −X axis direction side and an end on the + X axis direction side in the apparatus main body 12. That is, in the apparatus main body 12, the movement area of the carriage 40 is between the end on the −X axis direction side and the end on the + X axis direction side. In this embodiment, the end on the −X axis direction side in the movement region of the carriage 40 is set to the home position.

  As shown in FIG. 5, a platen 44 is disposed on the lower side of the carriage 40, that is, on the −Z axis direction side in the movement region of the carriage 40. Cap means 52 is provided at the end of the apparatus main body 12 on the −X axis direction side, that is, at the home position side in the movement region of the carriage 40.

  Further, as shown in FIG. 7, a reinforcing member 53 extending in the X-axis direction is attached to an end portion on the + Y-axis direction side of the lower surface of the platen 44. In the present embodiment, the reinforcing member 53 is formed of a highly rigid material, for example, a metal material. The reinforcing member 53 suppresses the bending of the platen 44 in the X-axis direction. Therefore, the distance (gap) between the recording head 42 and the platen 44 in the movement region of the carriage 40 can be maintained at a constant distance.

  On the upper surface of the platen 44, a plurality of ribs 54 that support the paper P are provided at intervals in the X-axis direction and the Y-axis direction. Further, a concave portion 56 as a “liquid receiving portion” is provided in a partial region of the platen 44 in the X-axis direction, and an ink absorber 58 is disposed in the concave portion 56. In the present embodiment, the recess 56 is provided near the end on the −X axis direction side in the X axis direction, which is a direction intersecting the Y axis direction that is the transport direction of the paper P.

  Here, in the printer 10, the paper P that can be recorded includes not only plain paper but also L-size photographic paper, postcards, and the like. The printer 10 according to the present embodiment is configured to perform borderless recording that performs recording on the entire recording surface of a small-sized sheet (hereinafter referred to as “small-sized sheet”) such as L-size photographic paper or a postcard. .

  The lengths of the concave portion 56 and the ink absorber 58 in the present embodiment in the X-axis direction are set to lengths at which the printer 10 can perform borderless recording on small-size paper. That is, the concave portion 56 and the ink absorber 58 are configured to be located in a region that is out of the end portion of the small size paper.

  In this embodiment, the ink absorber 58 is made of a sponge material. In other words, the ink absorber 58 disposed in the recess 56 can absorb and temporarily hold the ink discarded in the area off the edge of the small-size sheet when performing borderless recording.

  A plurality of holes are provided on the bottom surface of the recess 56. The ink absorber 58 includes a plurality of tongue pieces 58a (see FIGS. 8 and 9) extending to the lower side of the platen 44 through the holes. The plurality of tongue pieces 58a are “first liquid holding portions” disposed on the lower side (−Z-axis direction side) of the region where the concave portion 56 of the platen 44 is provided, that is, the region where the ink absorber 58 is disposed. Are in contact with the ink absorber 60.

  The ink absorber 60 is disposed below the platen 44 as shown in FIGS. Further, the ink absorber 60 is provided corresponding to the length of the concave portion 56 (ink absorber 58) in the X-axis direction in FIGS. In the present embodiment, the ink absorber 60 is made of a sponge material like the ink absorber 58.

  In the present embodiment, the ink discarded when borderless recording is performed on a small-size sheet is once absorbed by the ink absorber 58 disposed on the upper surface side of the platen 44, and then the platen 44 via the tongue piece 58a. The ink absorber 60 is guided from the upper side to the lower side and is absorbed and held by the ink absorber 60 in contact with the tongue piece 58a.

  In the present embodiment, since the ink absorber 60 is provided below the concave portion 56 that receives the ink ejected to the area off the edge of the paper P, the concave portion 56 promptly moves to the ink absorber 60. The liquid can be discharged.

  Although not shown, the ink absorber 60 is disposed in a recess provided on the bottom surface of the housing 14 that covers the apparatus main body 12. By disposing the ink absorber 60 in the concave portion, it is possible to prevent the ink absorbed by the ink absorber 60 from leaking into the apparatus main body 12.

  Referring to FIGS. 5 to 7 again, an opening 44a is provided at the end of the platen 44 on the −X axis direction side, and a cap means 52 is provided in the opening 44a. That is, the cap unit 52 is adjacent to the ink absorber 58 disposed on the upper surface side of the platen 44 and the ink absorber 60 disposed on the lower surface side of the platen 44.

  Further, a pump 62 is provided on the −Y axis direction side of the cap means 52 in the apparatus main body 12. The pump 62 is connected to the cap means 52 by a waste ink tube 64.

  The cap means 52 faces the recording head 42 when the carriage 40 is positioned at the home position, and is pressed against a nozzle formation surface (not shown) of the recording head 42 to seal the nozzle formation surface and to supply ink. Drying can be prevented. The cap means 52 is configured to be able to take a sealed state pressed against the recording head 42 and a separated state separated from the recording head 42.

  Further, when the cap unit 52 is in a sealed state with respect to the recording head 42, when the pump 62 is driven, a negative pressure is generated in the cap unit 52 through the waste ink tube 64. With this negative pressure, ink is sucked from the nozzles of the recording head 42 so that clogging of the nozzles and mixing of bubbles can be eliminated.

  Further, a flushing operation is performed at a fixed timing during execution of a recording operation in the printer 10. This flushing operation is an operation in which the carriage 40 is temporarily moved to the home position, and ink is ejected toward the cap means 52 to be discarded.

  Waste ink generated in the cap means 52 is sucked through the waste ink tube 64 by the pump 62. The sucked waste ink is accommodated in a waste ink cartridge 68 as a “second liquid holding unit” connected to a waste ink tube 66 extending from the pump 62.

  Next, the handling of the waste ink tube 66 and the arrangement of the waste ink cartridge 68 on the platen 44 will be described with reference to FIGS. A cartridge mounting portion 70 to which the waste ink cartridge 68 can be attached and detached is provided below the platen 44 (−Z axis direction side). The waste ink cartridge 68 is disposed on the lower side of the platen 44 near the end on the + X axis direction side of the platen 44 while being connected to the cartridge mounting portion 70.

  That is, the waste ink cartridge 68 is arranged in parallel with the ink absorber 60 in the Y-axis direction while being connected to the cartridge mounting portion 70. The waste ink tube 66 has one end connected to the pump 62 and the other end connected to the cartridge mounting portion 70.

  The waste ink tube 66 is routed around the lower side (−Z-axis direction side) of the platen 44. Specifically, the waste ink tube 66 drawn out from the pump 62 extends in the + X-axis direction through the space between the reinforcing member 53 and the ink absorber 60 at the + Y-axis direction end of the platen 44.

  In other words, the end of the platen 44 on the + Y axis direction side extends from the −X axis direction toward the + X axis direction. Then, as shown in FIGS. 6 and 7, the waste ink tube 66 extends between the ink absorber 60 and the cartridge mounting portion 70, that is, the waste ink cartridge 68 in the X-axis direction, and extends toward the −Y-axis direction side. The mounting portion 70 (waste ink cartridge 68) is connected to the cartridge mounting portion 70 at a position facing the ink absorber 60.

  Therefore, when the waste ink cartridge 68 is connected to the cartridge mounting portion 70, the cap means 52 and the waste ink cartridge 68 are in communication with each other via the waste ink tube 66, the pump 62, and the waste ink tube 64. As a result, the ink that has been discarded by the cap means 52 and sent out by the pump 62 can be held in the waste ink cartridge 68.

  In this embodiment, the waste ink tube 64 connecting the pump 62 and the waste ink cartridge 68 passes between the ink absorber 60 and the waste ink cartridge 68 and is located at a position facing the ink absorber 60 in the waste ink cartridge 68. Since it is connected, it is not necessary to secure a region for disposing the waste ink tube 64 outside the waste ink cartridge 68, and the printer 10 can be downsized.

  In this embodiment, the waste ink cartridge 68 and the ink absorber 60 have the following relationship with the platen 44. That is, the ink absorber 60 related to borderless recording and the waste ink cartridge 68 related to nozzle maintenance require a large occupied space inside the apparatus, which becomes a barrier against downsizing of the apparatus. On the other hand, the platen 44 that supports the paper P provided at a position that can face the recording head 42 also requires a large occupied space in the recording surface direction of the paper P, particularly in the paper width direction (X-axis direction). The length depends on the paper size. Therefore, in this embodiment, both the ink absorber 60 and the waste ink cartridge 68 are arranged using such a lower region (region on the −Z axis direction side) of the platen 44.

  More specifically, in this embodiment, the ink absorber 60 and the waste ink cartridge 68 are arranged below the platen 44 in the X-axis direction, which is a direction intersecting the Y-axis direction that is the conveyance direction of the paper P. Arranged. Thus, by using both the ink absorber 60 and the waste ink cartridge 68 in the lower region of the platen 44, the apparatus can be reduced in size while having the waste ink cartridge 68 and the ink absorber 60. .

  In this embodiment, the occupied area of the ink absorber 60 and the occupied area of the waste ink cartridge 68 are arranged so as to overlap in the Z-axis direction that is the apparatus height direction in the apparatus main body 12. Therefore, since the occupation area of the ink absorber 60 and the occupation area of the waste ink cartridge 68 overlap in the vertical direction, not only the recording surface direction of the paper P but also the size in the apparatus height direction can be reduced.

  Further, as shown in FIG. 8, the position of the bottom surface of the ink absorber 60 and the position of the bottom surface of the waste ink cartridge 68 in the Z-axis direction are the same position, that is, on the same plane. That is, although not shown in FIG. 8, the bottom portion 14 a (see FIG. 11) of the housing 14 supports the ink absorber 60 and the waste ink cartridge 68.
