Description

  The present invention relates to a recording apparatus, a platen that is a component of the recording apparatus, and a liquid ejecting apparatus. Here, the liquid ejecting apparatus uses an ink jet recording head, and is not limited to a recording apparatus such as a printer, a copying machine, and a facsimile machine that records ink on a recording medium by discharging ink from the recording head. The term “liquid” is used to include a device for ejecting a liquid corresponding to the application from a liquid ejecting head corresponding to the recording head to an ejecting medium corresponding to a recording medium and attaching the liquid to the ejecting medium.

  As the liquid ejecting head, in addition to the recording head, for example, a color material ejecting head used for manufacturing a color filter such as a liquid crystal display, an electrode material (conductive paste) used for forming an electrode such as an organic EL display or a surface emitting display (FED). ) A jet head, a bioorganic jet head used for biochip production, a sample jet head as a precision pipette, and the like.

  An ink jet recording apparatus includes a recording head mounted on a carriage that reciprocates in a main scanning direction, and a recording medium feeding unit that intermittently feeds a recording medium such as printing paper by a set amount in a sub scanning direction. Recording is performed by ejecting ink droplets from the recording head onto the recording medium while moving the head in the main scanning direction.

  The ink ejection characteristics of the recording head fluctuate due to solidification of ink on the nozzle formation surface, clogging of the nozzle due to adhesion of dust, dust, and the like, and entry of bubbles from the nozzle. In order to maintain the ink ejection characteristics of the recording head constant, the ink jet recording apparatus is usually provided with ejection characteristics maintaining devices such as a capping device, a suction device, and a wiping device. Among the discharge characteristic maintaining devices, the suction device is a state where the capping device seals the nozzle forming surface, applies a negative pressure to the nozzle opening, forcibly sucks and discharges ink from the nozzle opening, and clogging and Acts to remove entrained bubbles.

  The waste ink discharged from the recording head by the forcible discharge process of the ink by the suction device is guided to the waste liquid portion, and is held by the waste liquid absorbent material having a liquid absorbing property disposed in the waste liquid portion. Here, the waste liquid absorbing material plays a role of holding the ink so that the waste ink in the waste liquid portion does not leak to the outside even if the ink jet recording apparatus is inclined or subjected to vibration or the like.

  On the other hand, in models capable of printing (so-called borderless printing) in which the margin of the recording medium is zero, an opening or a groove is provided in the platen that faces the recording head in the recording section and supports the recording medium. For this purpose, a method of discarding ink is employed. The abandoned ink is absorbed by a porous absorbent material such as a sponge disposed in the opening or groove, and is finally guided to the waste liquid portion and held by the waste liquid absorbent material. In addition, an ink jet recording apparatus has been proposed in which materials having different porosity are stacked as the porous absorbent material and configured to promote the movement of the waste ink to the waste liquid portion (for example, Patent Document 1). .

  As described above, the waste liquid section has a function of holding waste ink from the suction device and waste ink collected through the platen, and prevents ink leakage and performs high-quality recording. It is an indispensable member. For this reason, the waste liquid portion having a sufficient capacity is usually arranged at a position below the platen so as to occupy a relatively large space with respect to the entire ink jet recording apparatus.

Japanese Patent Laid-Open No. 2003-211706

In recent years, the ink jet recording apparatus has also been miniaturized, and there is a strong demand for mounting necessary functions in a limited space. With regard to the waste liquid part, it is necessary to set the layout without impairing the function due to the limitation of the space of the entire apparatus. In addition, since it is necessary to allocate the waste liquid part to other members in a limited space, it is desirable to be able to flexibly handle various layouts. However, for example, in the conventional ink jet recording apparatus represented by Patent Document 1, it is assumed that the waste liquid portion is disposed below the platen. That is, in the conventional ink jet recording apparatus, since the arrangement of the waste liquid part is fixed, the degree of freedom in layout is greatly restricted.
Further, the waste liquid path is pushed up by the ink swelling in the waste liquid portion. Therefore, there is a possibility that the platen and the ink absorbing material provided in the platen are pushed up in conjunction with the waste liquid path, and the recording material and the recording head are contaminated.

  A first object of the present invention is to provide a recording apparatus provided with a waste liquid part that allows easy layout adjustment while maintaining a desired function even when installation space is restricted due to downsizing. A second object of the present invention is to provide a recording apparatus having a waste liquid path that can reliably guide waste ink to the waste liquid part even if the arrangement of the waste liquid part is changed. Furthermore, a third object of the present invention is to provide a recording apparatus provided with an absorption part in the waste liquid path, which can absorb a push-up due to ink swelling of the waste liquid part.

  In order to solve the above problems, a first aspect of the present invention is to apply a negative pressure in a state where a recording head for ejecting ink from a nozzle toward a recording medium and a nozzle forming surface of the recording head are sealed. A suction device that forcibly discharges the ink, a first waste liquid portion that stores waste ink sucked by the suction device, and waste ink that is discarded from the recording head toward the outside of the recording medium. And a second waste liquid section for storing the recording liquid.

  In the recording apparatus according to the first aspect, the waste ink discharged from the suction device by cleaning the recording head and the waste ink discarded outside the edge of the recording medium during recording such as so-called borderless printing are separated. It was set as the structure stored in a waste liquid part. With such a configuration, it is possible to give flexibility to the arrangement of the waste liquid part, and the degree of freedom of component layout of the recording apparatus is increased. Further, it becomes possible to accurately set the capacity according to the amount of waste ink in each of the first waste liquid part and the second waste liquid part. From the above, it is possible to save space of the waste liquid part and to increase the degree of freedom of member arrangement, and to easily cope with downsizing of the recording apparatus.

  According to a second aspect of the present invention, in the first aspect, a waste liquid path that guides the waste ink sucked by the suction device to the first waste liquid portion, and is discarded toward the outside of the recording medium. The recording apparatus is characterized in that a waste liquid path that guides the waste ink thus obtained to the second waste liquid section is provided independently. In the second aspect, since the two waste liquid paths leading to the first and second waste liquid parts are separate paths independent from each other, there are less restrictions on the arrangement, and the operational effects of the first aspect are more reliable. Is obtained.

  According to a third aspect of the present invention, in the first or second aspect, the first waste liquid portion and the second waste liquid portion are deviated from a position below a recording area where recording is performed by the recording head. Thus, the recording apparatus is characterized by being arranged separately.

  In general, the size of a recording apparatus is largely set according to the size of a recording medium that is a recording target. For this reason, the recording area occupies a large proportion of the entire recording apparatus. In this aspect, since the first waste liquid part and the second waste liquid part are arranged so as to be separated from directly below the recording area, for example, a collective space below the recording area where the conventional waste liquid tray is arranged is fed. It can be effectively used as a place for placing trays. Therefore, according to the 2nd mode, in addition to the same operation effect as the 1st mode, further miniaturization can be attained with effective use of the space in the device.

  According to a fourth aspect of the present invention, there is provided a platen according to any one of the first to third aspects, provided opposite to the recording head, for supporting the recording medium and defining a position with respect to the recording head. The recording apparatus is provided with a waste ink guide member that guides the waste ink, which is discarded toward the outside of the recording medium, to the second waste liquid portion.

  According to the fourth aspect, in addition to the same functions and effects as those of the first to third aspects, the waste ink guiding member is provided on the platen. The discarded waste ink can be reliably guided to the second waste liquid portion without causing liquid leakage or scattering. Therefore, maintenance of recording quality and reliability as a recording apparatus can be ensured.

  According to a fifth aspect of the present invention, in the fourth aspect, an absorbent material having an ink holding force smaller than that of the waste ink guiding member is laminated and disposed so as to cover the surface of the waste ink guiding member. It is a recording device.

  In the fifth aspect, the waste ink guiding member and the absorbent material are arranged in layers, so that the ink is discarded toward the absorbent material to suppress the generation of ink mist, and the waste ink is quickly permeated and absorbed. It becomes possible to make it. In addition, by using a material having a smaller ink holding force than the waste ink guide member as an absorbent material, it is possible to promote the movement and diffusion of the waste ink to the waste ink guide member, and to quickly guide the waste ink to the waste liquid portion. Become. Therefore, according to the recording apparatus of this aspect, the same effect as that of the fourth aspect is further ensured, and high-quality and highly reliable recording is realized.

  According to a sixth aspect of the present invention, in the fourth or fifth aspect, the waste ink guide member is formed in a sheet shape, is accommodated in a recess formed in the platen, and is folded near an end thereof. It is bent, and the end portion protrudes to the back side of the platen through the through opening of the platen to form a protruding piece, and the protruding piece is inserted into the second waste liquid portion. It is a recording device.

  In order to prevent the recording medium or the like from being soiled by the waste ink that has been discarded outside the edge of the recording medium, it is necessary to promptly guide the waste ink to the waste liquid portion. At that time, it is necessary to avoid a situation in which the waste ink wraps around the back surface along the wall surface of the platen or drops onto a place other than the waste liquid portion. In the recording apparatus of the sixth aspect, the waste ink guide member is bent in the vicinity of the end portion, and the end portion protrudes to the back side through the through opening of the platen, so that the waste ink is formed on the wall surface or the back surface of the platen. It is possible to prevent the ink from flowing around and reliably guide the waste ink to the second waste liquid portion. In particular, a through-opening is formed in the vicinity of the end of the platen, and a waste ink guide member is inserted from there to form a waste ink path leading from the platen surface to the outside of the recording area. As a result, the possibility of ink sneaking into the area directly under the platen can be greatly reduced, so even if a paper feed tray or the like is provided in this area, there is no risk of being contaminated by waste ink, and effective use of the device space can be achieved. It becomes possible to plan.

  According to a seventh aspect of the present invention, there is provided a recording head for ejecting ink from a nozzle toward a recording medium, and the recording head provided opposite to the recording head, and supporting the recording medium and defining a position relative to the recording head. A plurality of ribs for supporting the recording medium, and a recess is formed so as to surround the rib. Includes a sheet-shaped waste ink guide member, and an absorbent material having a smaller ink holding force than the waste ink guide member is disposed so as to cover the surface of the waste ink guide member, The waste ink guide member is bent in the vicinity of an end thereof, and the end protrudes to the back side of the platen through a through opening of the platen to form a projecting piece, thereby forming a waste liquid path to the waste liquid portion. That make up The symptom is a recording device.

  In the recording apparatus according to the seventh aspect, the waste ink guide member and the absorbent material are stacked in the concave portion of the platen. The absorber has an action of suppressing generation of ink mist when the ink is discarded and allowing the waste ink to rapidly permeate and absorb. In addition, by using a material having a smaller ink holding force than the waste ink guide member as an absorbent material, it is possible to promote the movement and diffusion of the waste ink to the waste ink guide member, and to quickly guide the waste ink to the waste liquid portion. Become.

  Also, the waste ink guide member is bent in the vicinity of the end portion, and the end portion protrudes to the back side through the through opening of the platen, thereby preventing the waste ink from wrapping around the wall surface or back surface of the platen. It is possible to reliably lead to the waste liquid part. In particular, a through-opening is formed in the vicinity of the end of the platen, and a waste ink guide member is inserted from there to form a waste ink path leading from the platen surface to the outside of the recording area. As a result, the possibility of ink flowing into the area directly under the platen can be greatly reduced. Even if a paper feed tray, for example, is provided in this area, there is no risk of contamination due to waste ink, and the device space is effectively utilized. it can.

  According to an eighth aspect of the present invention, in the seventh aspect, the pressing member includes a pressing member and a means for fixing the pressing member to the platen, and is disposed at least near the bent portion of the waste ink guiding member of the platen recess.

The waste ink guide member can be pressed directly.
Further, when the thickness of the waste ink guide member is increased, it is difficult to bend at a right angle even with bending, and the vicinity of the bent portion of the waste ink guide member is easily separated from the platen. At this time, since the pressing member is disposed in the vicinity of the bent portion of the waste ink guiding member, the waste ink guiding member can be directly pressed, and there is no possibility of being separated from the platen.
Further, there is no possibility that the waste ink guide member is separated from the platen due to the protrusion of the protrusion due to the ink swelling of the waste ink absorber in the waste liquid portion.

  According to a ninth aspect of the present invention, in the eighth aspect, the pressing member presses the ink absorbing material across the longitudinal direction of the ink absorbing material.

According to the ninth aspect, since the ink absorbing material is pressed across the longitudinal direction, it can be pressed more firmly. That is, since the waste ink guide member is easily separated from the platen in the vicinity of the bent portion formed in the waste ink guide member, the portion that is easily separated can be surely pressed by pressing it across the longitudinal direction. it can.
In addition, since the through opening of the waste ink guiding member through which the pressing member is inserted is disposed in the longitudinal direction, the movement of the waste ink is not hindered.

In the vicinity of the narrow end portion, the bent portion 57b is bent at a substantially right angle to form a tongue piece 57a as a “projection piece”. As shown in FIGS. 6 and 7, the tongue piece 57 a is inserted into a through portion (not shown) provided in the base 51 of the platen 50. Further, the tongue piece 57a is once narrowed gradually toward the end portion, and its tip (portion immediately adjacent to the end portion) is widened again, and this widened portion has a retaining action.

  A through portion (not shown) of the platen 50 is provided at a position off the recording area. Therefore, the guide sheet 57 extended in the concave portion 55 of the platen 50 moves the waste ink in the lateral direction, and the waste ink is removed from the back side of the platen 50 through the penetrating portion of the platen 50 at a position outside the recording area. It is configured so that it can be guided to.

  The material of the induction sheet 57 is not particularly limited as long as it has a predetermined liquid absorption performance, but as a sponge material, for example, a porous material such as polyvinyl formal sponge [for example, Belita (trade name; manufactured by Kanebo Kasei Co., Ltd.)] or the like. A quality material can be used. The absorbent sheet 59 can also be made of a porous material such as sponge. Here, the guide sheet 57 is made of a material having higher ink holding performance than the laminated absorbent sheet 59. In general, in a porous body having liquid absorption performance, the performance of absorbing and holding liquid such as ink tends to be higher when the porosity is lower. Therefore, as the guide sheet 57, a material having a lower porosity than the absorbent sheet 59 is suitable.

  The absorbent sheet 59 is formed slightly thicker than the guide sheet 57. Further, by using a material having a high porosity and excellent liquid permeability as the absorbent sheet 59, clogging due to pigments contained in the ink is less likely to occur, and the absorption performance can be maintained over a long period of time. become. That is, the absorbing sheet 59 functions as a waste ink absorbing unit.

As described above, since the ink holding force of the guide sheet 57 is greater than that of the absorbent sheet 59, the waste ink discharged on the surface of the absorbent sheet 59 penetrates and is absorbed by the absorbent sheet 59, and then relatively quickly reaches the lower layer. The process proceeds to the guide sheet 57.
That is, the waste ink transferred to the guide sheet 57 is diffused and held through the gap of the guide sheet 57, and the tongue piece 57a is passed through a through hole (not shown) provided in the base 51 of the platen 50. And the waste ink is guided to the back side of the platen 50. Thus, the guide sheet 57 functions as waste ink guide means.

Next, the waste ink guiding member 92 housed in the platen 91 and the pressing members 94 and 95 for pressing the ink absorbing material 93 will be described with reference to FIGS. 11 to 14.
As shown in FIGS. 11 and 12, the pressing member 94 has a convex portion 94 b on the lower surface and is formed so as to fit between the ribs of the platen 91. The pressing member 94 is arranged in the longitudinal direction of the central portion on the upper surface of the ink absorbing material 93, and the convex portion 94b is press-fitted between the ribs through a through opening 93c provided in the ink absorbing material 93. Mated. As a result, it is possible to suppress the rising of the waste ink guiding member 92 and the ink absorbing material 93 due to the swelling of the ink. As a result, there is no possibility that the ink absorbing material 93 will come into contact with the recording material passing through the upper surface of the platen 91 and get dirty. Further, since the pressing members 94 are arranged in the longitudinal direction, there is no possibility that the ink movement of the waste ink guiding member 92 is hindered. The operations of the platen 91, the waste ink guiding member 92, and the ink absorbing material 93 are the same as in FIG.

  Next, as shown in FIG. 12, the pressing member 95 includes a convex portion 95 b on the lower surface for the same purpose as the convex portion 94 b of the pressing member 94. Similar to the through opening 93c, the ink absorbing material 93 has a through opening 93d through which the convex portion 95b can be inserted. The platen 91 is formed with a pressing member receiving portion 91f into which the convex portion 95b is press-fitted. Further, the waste ink guiding member 92 is formed with a through opening 92c through which the pressing member receiving portion 91f is inserted. The convex portion 95b is inserted into the through-opening portion 93d and is press-fitted into the pressing member receiving portion 91f via the through-opening portion 92c.

  Similarly, the protrusion 95 a provided on the pressing member 95 is formed to have a length substantially equal to the thickness of the ink absorbing material 93 and is inserted into the through opening 93 a formed in the ink absorbing material 93. Thereby, the convex part 95a can contact | abut and hold | suppress the waste ink guide member 92 upper surface via the through-opening part 93a. FIG. 13 shows a state where the ink absorbing material is removed from FIG. Thus, the pressing member 95 functions as a means for pressing both the ink absorbing material 93 and the waste ink guiding member 92.

  On the other hand, when the thickness of the waste ink guiding member 92 is increased in order to increase the ink remaining rate of the waste ink guiding member 92, the bent portion of the through hole insertion portion 92d (see FIG. 14) formed by bending is a right angle. It becomes difficult to bend, and it becomes easy to become a bending shape with a curved surface part. Accordingly, when the through hole 91e (see FIGS. 11, 16, and 17) provided in the base plate of the platen 91 is inserted, the gap between the waste ink guide member 92 accommodated in the platen recess and the through hole insertion portion 92d. Since the bent portion has the curved surface portion, the bent portion may be separated from the bottom surface of the concave portion of the platen 91. Therefore, by disposing the pressing member 95 in the vicinity of the through hole 91 e, there is no possibility that the waste ink guiding member 92 is separated from the bottom surface of the concave portion of the platen 91.

Further, since the pressing member 95 is formed so as to press the ink absorbing material 93 across the longitudinal direction of the ink absorbing material 93, the waste ink guiding member 92 and the ink absorbing material 93 can be pressed more firmly. Thus, since the ink absorber 97 in the waste liquid portion 96 (see FIG. 16) swells and the protruding piece 92b is pushed up, the waste ink guiding member 92 remains on the bottom surface of the concave portion of the platen 91. There is no fear of being separated from.
As a result, there is no possibility that the ink absorbing material 93 will come into contact with the recording material passing through the upper surface of the platen 91 and get dirty, and good recording can be performed.

  Further, as shown in FIG. 14, when the through openings 92 c formed in the waste ink guiding member 92 are arranged in the longitudinal direction, the reduction in the cross-sectional area of the waste liquid path is one cross-sectional area of the through-opening 92. Minutes. On the other hand, when arranged in the short direction, the cross-sectional area of the waste liquid path decreases in units of the cross-sectional area of the through opening 92. That is, even if a plurality of through openings 92 are arranged in the longitudinal direction, the cross-sectional area is the same as when a single through opening 92 is arranged. Therefore, even if the through openings 92c are arranged in the longitudinal direction, there is no possibility that the ink movement is hindered. As a result, the waste ink discarded on the platen 91 is quickly guided to the waste liquid portion 96.

  Near the end of one side of the platen 50, a waste liquid tank 70 is disposed in a positional relationship as shown in FIG. The waste liquid tank 70 includes a synthetic resin case 71 and an ink absorber 73 disposed therein. Any material can be used as the material of the ink absorber 73 as long as it has liquid absorption performance. However, in this embodiment, the ink absorber 73 is configured by laminating sheet-like nonwoven fabrics. 9 shows a state where the synthetic resin case 71 of the waste liquid tank 70 is removed.

  As described above, the guide sheet 57 accommodated in the concave portion 55 of the platen 50 has the tongue piece 57a to be inserted into the through hole (not shown) of the platen 50. This tongue piece 57a hangs down from the platen 50 to reach the ink absorber 73 of the waste liquid tank 70. Further, the widened portion in the vicinity of the end portion having a slightly widened retaining portion of the tongue piece 57a absorbs the ink. It is inserted into the body 73. The waste ink discharged to the ink receiving portion of the platen 50 penetrates the absorption sheet 59 and is promptly guided to the waste liquid tank 70 through the waste liquid path connected to the guide sheet 57 and the tongue piece 57a. .

  FIG. 15 is a perspective view of the waste liquid part (second waste liquid part) and the platen excluding the case of the waste liquid part. The waste ink guiding member 92 accommodated in the concave portion of the platen 91 has a projecting piece 92 b that is inserted into the through hole 91 e of the platen 91. As shown in FIGS. 15 and 16, the protrusion 92b is inserted between the inner surface 96a of the waste liquid portion and the ink absorber side surface 97b. As the ink swells, the ink absorber 97 is forced to spread. However, the force to spread is restricted by the inner surface 96a of the waste liquid part. Therefore, the projecting piece 92b inserted between them has no fear of moving under a force in a direction perpendicular to the inner side surface 96a. As a result, the waste liquid path and the platen 91 are forced through the protrusions 92b in a direction perpendicular to the inner side surface 96a, in other words, in the present embodiment in the longitudinal direction of the platen 91 (see FIGS. 11, 15, and 16). There is no risk of receiving.

  Here, when the force to be expanded is not restricted by the inner surface 96a, the waste ink guiding member 92 is pushed or pulled by the force to be expanded, and the through hole insertion portion 92d is slightly bent. There is a risk of deformation. Due to the deformation, the waste ink guiding member 92 may be separated from the bottom surface of the concave portion of the platen 91.

Further, since the surface of the protrusion 92b and the ink absorber side surface 97b abut, the movement and diffusion of the waste ink from the protrusion 92b to the ink absorber 97 can be performed quickly.
Further, a groove 97a is formed on the side surface 97b of the ink absorber disposed in the waste liquid portion 96, and the protruding piece 92b is fitted into the groove 97a. As a result, the contact area between the projecting piece 92b and the ink absorber 97 is widened, so that the movement and diffusion of the waste ink can be performed more rapidly.

  In this embodiment, the waste liquid tank 70 is provided separately from the waste liquid tank 60, so that the capacity of the waste liquid tank 70 can be minimized and disposed in a relatively small space. Further, the waste liquid tank 60 and the waste liquid tank 70 are arranged so as to be out of the recording area in the main scanning direction. As a result, in the present embodiment, the paper feed tray 30 can be accommodated in a collective space immediately below the recording area where the waste liquid tank is disposed in the conventional printer, so that the limited apparatus space can be effectively utilized. It has become.

  FIG. 10 is a perspective view showing an outline of the waste liquid tank 60 connected to the discharge characteristic maintaining device 80. The discharge characteristic maintaining device 80 is disposed at a position corresponding to the home position of the carriage 13 (in the vicinity of the right side frame 6 in FIG. 2), and includes a cap 81, a wiping member 82, and a suction pump as a “suction device”. 83, and performs capping, wiping, suction cleaning, and the like. Further, in the discharge characteristic maintaining device 80, a waste liquid tank 60 is connected to a back side as viewed from the front of the printer 1 by a waste liquid pipe 85 to form a waste liquid path.

  The waste liquid tank 60 includes a synthetic resin case 61 and an ink absorber 63 accommodated in the synthetic resin case 61. The ink absorber 63 can be used without particular limitation as long as it is a material having a liquid absorption performance. In this embodiment, the ink absorber 63 is configured by laminating sheet-like nonwoven fabrics in the lateral direction. The waste liquid tank 60 is reduced in size by subtracting the capacity of the waste liquid tank 70 described above, and can be disposed on the rear portion of the discharge characteristic maintaining device 80 at a position deviated from the recording area in the main scanning direction. It has become. Further, in the printer 1 of the present embodiment, the position where the waste liquid tank 60 is provided is a place where it is easy to take a space in the height direction, and thus the waste liquid tank 60 has a sufficiently high shape. Accordingly, the ink absorber 63 accommodated in the waste liquid tank 60 is stacked in the horizontal direction so that the waste ink introduced from the lower part of the tank through the waste liquid pipe 85 is likely to permeate upward. ing.

  The present invention has been described above with reference to various embodiments. However, the present invention is not limited to the above embodiments, and can be applied to other embodiments within the scope of the invention described in the claims. It is.

  For example, in the printer 1 according to the above embodiment, the waste liquid tank 60 and the waste liquid tank 70 are disposed so as to be separated from each other by the recording area. However, the present invention is not limited to such an arrangement. For example, the waste liquid tank 70 is disposed on the home position side. It is also possible to arrange it adjacent to the tank 60. Further, the advantage of the degree of freedom in layout due to the division of the waste liquid tank can be obtained even when the waste liquid tank 60 and the waste liquid tank 70 are arranged at other locations.

  An example of the “absorbing part” according to the present invention will be described with reference to FIG. 14, FIG. 16, and FIG. Here, FIG. 14 is an enlarged perspective view of a main part in which the waste ink guiding member and the pressing member are extracted from FIG. 11, FIG. 16 is a perspective view of the platen and the waste liquid part (second waste liquid part), and FIG. It is a principal part downward perspective view of a waste ink guide member.

  An absorbing portion 90 that absorbs the pushing up of the protrusion 92b caused by the ink swelling of the ink absorber 97 provided in the waste liquid portion 96 is formed in the waste liquid path. The absorption part 90 has a through-hole insertion part 92d to be inserted into the through-hole 91e of the platen 91, a flat part 92a, and a protruding piece 92b. As shown in FIG. 12, the waste ink guiding member 92 is initially formed from one surface. As shown in FIG. 14, the through-hole insertion part 92d, the plane part 92a, and the protrusion 92b are formed by bending. In the present embodiment, the through hole insertion portion 92d is formed so as to hang down from the platen 91 so as to be inserted into the through hole 91e. The flat portion 92a is formed on a surface substantially parallel to the waste ink guiding member 92 accommodated in the concave portion of the platen 91, and is formed in an L-shaped surface in this embodiment.

  The projecting piece 92b at the tip is in contact with the ink absorber 97 in the waste liquid portion 96 shown in FIG. The waste ink discharged to the ink receiving portion of the platen 91 penetrates into the ink absorbing material 93 and passes through the waste liquid path that leads to the waste ink guiding member 92, the flat surface portion 92a, and the protruding piece 92b. The ink is quickly guided to the ink absorber 97. As a result, the ink absorber 97 swells, and due to the swelling in the thickness direction, a force for pushing up the protruding piece 92b is generated. The pushing force is absorbed by the surface of the flat portion 92a being bent. Further, the pushing-up force can be absorbed even when the end portion of the flat portion 92a, in other words, the bent portion formed by bending is further bent. As a result, the force that pushes up the protruding piece 92b due to the swelling of the ink absorber 97 is absorbed by the absorbing portion 90, so that the platen 91 and the ink absorbing material 93 can be prevented from being pushed up.

  Further, since the bearing 91a of the paper discharge roller shaft (not shown) provided on the platen 91 shown in FIG. 11 is pressed by the paper discharge roller shaft (not shown), the platen 91 can be prevented from being pushed up. .

  In addition, when the pushing-up force is large, the flat surface portion 92a may come into contact with the lower surface of the platen 91, and the pushing-up force may not be absorbed. In this case, as shown in FIG. 16, by removing a part of the flat surface portion 92a from the lower surface area of the platen 91, it is possible to avoid the flat surface portion 92a from coming into contact with the lower surface of the platen 91 and to absorb the pushing-up force. Is possible. Further, as shown in FIG. 16, by removing a part of the flat part 92 a from the lower surface area of the platen 91, it can be easily recognized whether the ink has permeated the flat part 92 a that is a part of the waste liquid path.

  Further, even if the ink absorber 97 is twisted due to swelling, the planar portion 92a has an L-shaped surface, so that the twisting force can be absorbed by twisting the L-shaped surface.

  As a result, it is possible to prevent the platen 91 and the ink absorbing material 93 from being pushed up, so that the recording material and the recording head are not likely to be stained with the waste ink of the ink absorbing material 93, and good recording can be performed.
