By the way, in the recording apparatus, a pair of discharge rollers for discharging the recorded paper is provided, and the pair of discharge rollers includes a drive roller that is rotationally driven by a motor and a driven roller that is disposed to face the drive roller. May be configured. In particular, in the case of an ink jet printer, the driven roller is often a spur (sometimes called a star wheel) that makes point contact with the recording surface in order to prevent transfer of ink or white spots.
A plurality of spurs are supported at predetermined intervals along the paper width direction by a frame extending in the paper width direction.

  When this frame is formed of, for example, a resin material for the purpose of reducing the cost of the apparatus, warping may occur along the paper width direction. Such warpage may occur not only immediately after resin molding but also with time as the apparatus is used. When the frame is warped, the position of the driven roller with respect to the driving roller changes, and in particular, if the driven roller is separated from the driving roller, the conveyance force may not be applied to the paper, which may cause a discharge failure. Further, in borderless printing in which recording is performed on the four sides of the paper without margins, the paper is transported by the discharge roller pair when recording is performed on the trailing edge of the paper, so that the driven roller is separated from the driving roller as described above. And cannot be recorded properly.

  Accordingly, the present invention has been made in view of such a situation, and an object of the present invention is to provide a recording apparatus that can achieve both of cost reduction of the apparatus and appropriate paper feeding operation over a long period of time. It is in.

The second roller has a shape that extends in a direction that intersects the conveyance direction of the recording medium.

  According to this aspect, since the support member that has a shape extending in the direction intersecting the conveyance direction of the recording medium and that holds the second roller is configured to support the tube, the support member applies an external force from the tube. In response, the second roller suppresses deformation of the support member in a direction away from the first roller. That is, since the tube is used as a means for suppressing the deformation of the support member, it is possible to achieve both the cost reduction of the apparatus and the appropriate recording medium feeding operation over a long period of time.

  According to a second aspect of the present invention, in the first aspect, the tube extends from the carriage in a first direction that is a movement direction of the carriage, and then curves downward, with respect to the first direction. The tip section turned back in the second direction, which is the opposite direction, is supported by the support member.

  According to this aspect, the tube extends from the carriage in the first direction which is the movement direction of the carriage, then curves downward, and then turns back in the second direction which is opposite to the first direction. Since the tip section is supported by the support member, the support member receives a repulsive force accompanying the folding (curving) of the tube from the tube. Thereby, the deformation of the support member can be more effectively suppressed.

According to a third aspect of the present invention, in the first or second aspect, at least a part of the tube is fixed to the support member.
According to this aspect, since at least a part of the tube is fixed to the support member, it is possible to prevent the tube from being ramped as the carriage moves, and the support member reliably receives external force from the tube. be able to.

According to a fourth aspect of the present invention, in any one of the first to fourth aspects, the support member includes a guide portion that guides the tube in a predetermined direction.
According to this aspect, since the support member has the guide portion that guides the tube in a predetermined direction, the tube can be guided in an appropriate direction, and there is no need to separately provide such a guide means. , Low cost can be achieved.

According to a fifth aspect of the present invention, in any one of the first to fourth aspects, the tube includes a plurality of tubes, and the plurality of tubes intersects the transport direction of the recording medium on the support member. And extending in a direction along which the recording medium is conveyed.

According to this aspect, the tube includes a plurality of tubes, and the plurality of tubes extend on the support member in a direction intersecting the transport direction of the recording medium and the transport direction of the recording medium. Accordingly, the support member receives an external force in a wide range from a plurality of tubes. As a result, the deformation of the support member in the direction in which the second roller is separated from the first roller can be more effectively suppressed.

According to a sixth aspect of the present invention, in any one of the first to fifth aspects, a guide member for guiding the tube is provided adjacent to the tube.
According to this aspect, since the guide member for guiding the tube is provided adjacent to the tube, the behavior of the tube when the tube moves along with the movement of the carriage is stabilized.

Yes, also in the horizontal direction of the device. In addition, the y direction is the paper transport direction and is also the apparatus depth direction. Furthermore, the z direction is the direction of gravity and is also the device height direction.

  Hereinafter, the configuration of the printer 1 will be outlined with reference mainly to FIGS. 1 and 2. The printer 1 has an ink container 6 on the right side (right when viewed from the front of the apparatus) of the apparatus main body 2 that performs ink jet recording on a recording sheet (hereinafter referred to as “sheet P”) as an example of a recording medium. . The ink storage unit 6 stores a plurality of colors (for example, yellow, cyan, magenta, and black), and is configured so that ink is supplied from the ink storage unit 6 to a carriage 8 (recording head 10) described later. Has been. That is, the printer 1 is a so-called off-carriage type in which no ink cartridge is mounted on the carriage 8 (details will be described later).

  The printer 1 has a paper support 4 that supports the paper P in an inclined posture at the rear of the apparatus, and the paper P is sent out one by one by a paper feed mechanism (not shown). The fed paper P reaches a transport driving roller 16 and a transport driven roller 17 as a paper transport means.

  The transport driving roller 16 is rotationally driven by a motor (not shown), and the transport driven roller 17 is driven to rotate by nipping the paper P with the transport driving roller 16. On the downstream side of these rollers, a recording head 10 as recording means for ejecting ink onto the paper P and a paper support member 15 that supports the paper P are provided. The recording head 10 is provided at the bottom of the carriage 8 driven in the paper width direction (main scanning direction). The carriage 8 moves in the main scanning direction under the driving force of the drive motor 22 (FIG. 3) while being guided in the main scanning direction by guide means (not shown) extending in the main scanning direction.

  A discharge driving roller 19 as a first roller and a discharge driven roller 20 as a second roller are provided on the upper side of a region (recording region) where the paper support member 15 and the recording head 10 face each other. Yes. The discharge driving roller 19 is rotated by receiving power from a motor (not shown), and the discharge driven roller 20 is driven to rotate by contacting the recording surface of the paper P. In the present embodiment, the discharge drive roller 19 is configured by a rubber roller, and a plurality of discharge drive rollers 19 are provided at appropriate intervals in the paper width direction.

In the present embodiment, the discharge driven roller 20 is constituted by a jagged roller (spur), and a plurality of discharge driven rollers 20 are provided at an appropriate interval in the paper width direction. In the present embodiment, the discharge driven roller 20 is not provided so as to face all of the plurality of discharge drive rollers 19 provided along the paper width direction, and faces a part of the discharge drive rollers 19. Has been placed.
The recorded paper P is discharged from the discharge port 3 (FIG. 1) to the front side of the apparatus by the discharge driving roller 19 and the discharge driven roller 20.

  Next, the carriage 8, the ink storage unit 6, the ink tube 12, and the tube support member 31 will be described in detail with reference to FIG. As described above, the carriage 8 is a type in which no ink cartridge is mounted, and ink as a liquid is transferred from the ink storage portion 6 provided on the right side surface of the apparatus via the plurality of ink tubes 12 to the carriage 8 (recording head 10). ).

The ink container 6 is composed of a plurality of ink containers 6a, 6b, 6c, and 6d so as to correspond to a plurality of colors of ink, and the plurality of ink tubes 12 are connected to the ink containers 6a to 6d. Ink is supplied to the recording head 10 side.
In the present embodiment, each of the ink storage portions 6a to 6d is configured to be able to inject ink from the outside (detailed description is omitted). Each of the ink storage portions 6a to 6d is provided with an ink pack (not shown), and the ink pack can be replaced.

  On the other hand, the carriage 8 is provided with relay adapters 9a, 9b, 9c, 9d corresponding to each color of a plurality of colors of ink, and the plurality of ink tubes 12 are connected to the relay adapters 9a to 9d. Ink is supplied to the recording head 10 via 9a to 9d.

  A tube extending portion 8a is formed on the front side of the carriage 8, and the plurality of ink tubes 12 extend in parallel from the tube extending portion 8a to the left side (x + direction) of the apparatus. Then, it is folded back to the right side of the apparatus (x-direction) halfway, extends to the right side of the apparatus along the upper part of the tube support member 31, and reaches the ink containing portion 6. The plurality of ink tubes 12 are supported by the tube support member 31 and partially fixed to the tube support member 31 by the tube fixing member 29. In FIG. 8, the tube fixing member 29 is not shown.

  Here, the ink tube 12 has flexibility, and the ink tube 12 is deformed following the movement of the carriage 8. FIG. 3 shows a state in which the carriage 8 is in the home position region (x− side), and FIG. 4 shows a state in which the carriage 8 is at a position farthest from the home position (x + side). As is clear from FIGS. 3 and 4, the ink tube 12 is deformed following the movement of the carriage 8, and in particular, the position of the folded portion (curved portion) 12 a changes as the carriage 8 moves.

  A guide member 13 for guiding the ink tube 12 is provided adjacent to the ink tube 12 as shown in FIGS. 3, 4, and 8. The guide member 13 is a flexible sheet-like member and can be formed of, for example, PET (polyethylene terephthalate). The guide member 13 is deformed similarly to the ink tube 12 following the movement of the carriage 8. 6 and 9, the guide member 13 is not shown.

  By providing the guide member 13 in this manner, the ink tube 12 is not easily exposed when the ink tube 12 moves as the carriage 8 moves, and the behavior of the ink tube 12 is stabilized. Further, the guide member 13 is provided between the ink tube 12 and the tube support member 31, and the ink tube 12 does not directly contact the tube support member 31. Since the guide member 13 is a flat sheet material having a flat surface, it is possible to suppress wear and scraping of the ink tube 12 when the ink tube 12 moves as the carriage 8 moves.

  Next, the tube support member 31 has a shape extending in the direction (x direction) intersecting the paper transport direction, and is formed integrally by resin molding, and forms a base frame of the entire printer 1. It is attached and fixed to 26. FIG. 7 is a diagram (disassembled perspective view) showing a state in which the tube support member 31 is removed from the base frame 26. The attachment position of the tube support member 31 in the apparatus depth direction (y direction) is the apparatus front side (y + side) of the carriage 8.

  The tube support member 31 has a tube guide portion 31a that guides the right end portion (x-direction end portion) so as to change the direction of the ink tube 12 downward. The ink tube 12 is temporarily guided downward by the tube guide portion 31a toward the ink storage portion 6 and guided to the concave portion 26a (FIG. 5) formed in the base frame 26. Bent to the portion 6 side (bent in the y-direction: FIG. 6) and connected to each of the ink storage portions 6a to 6d.

As described above, the tube support member 31 has a function of supporting and guiding the ink tube 12 on the one hand as described above, and constitutes a paper transport path on the other hand as follows.
That is, the tube support member 31 is provided with a roller holding portion 31b at an appropriate location along the x direction as shown in FIGS. 10, 11, and 12, and the discharge support roller is provided on the roller support portion 31b. 20 (FIG. 2) is held so as to be driven to rotate.

  The formation position of the roller support portion 31b corresponds to the position where the discharge drive roller 19 is disposed. However, in this embodiment, the roller support portions 31b (discharge driven rollers 20) are not provided for all the discharge drive rollers 19, and the roller support portions 31b (discharge driven rollers 20) for some of the discharge drive rollers 19. Is provided. Further, the discharge driven roller 20 is held at a position where it does not protrude from the upper surface of the tube support member 31, as is apparent from FIG. That is, the discharge driven roller 20 does not contact the ink tube 12 supported by the tube support member 31.

  On the other hand, a regulating unit 32 that regulates the lifting of the paper P is provided between the recording head 10 and the discharge driven roller 20 in the paper conveyance path. The regulation unit 32 regulates the sheet floating between the recording head 10 and the discharge driven roller 20, and the contact of the sheet P with the recording head 10 and the gap between the recording head 10 and the sheet P are inappropriate. It is possible to prevent or suppress the deterioration of the recording quality due to the fact that

  In particular, after the trailing edge of the sheet is removed from between the conveyance driving roller 16 and the conveyance driven roller 17, the sheet P is nipped only by the discharge driving roller 19 and the discharge driven roller 20. The float on the upstream side of the roller 20, that is, the rear end side of the sheet is likely to occur. As a result, the recording quality at the trailing edge of the sheet is likely to deteriorate, particularly when borderless recording is performed in which recording is performed without a margin at the trailing edge of the sheet.

  However, as described above, the regulation unit 32 that regulates the floating of the paper P is provided between the recording head 10 and the discharge driven roller 20, so that the paper floating between the recording head 10 and the discharge driven roller 20 occurs. In particular, even after the trailing edge of the sheet is removed from between the transport driving roller 16 and the transport driven roller 17, appropriate recording can be performed.

  In order to prevent the sheet from floating, the nip point between the transport driving roller 16 and the transport driven roller 17 is set slightly downstream from the rotation center of the transport driving roller 16. As a result, the paper P delivered from the transport driving roller 16 and the transport driven roller 17 is in a state of being pressed against the paper support member 15, thereby suppressing the paper floating.

  Similarly, the nip point between the discharge drive roller 19 and the discharge driven roller 20 is set slightly upstream from the rotation center of the discharge drive roller 19. As a result, the portion of the paper P upstream of the nip position between the discharge driving roller 19 and the discharge driven roller 20 is pressed against the paper support member 15, and the paper floating is suppressed.

  By setting the roller nip point as described above, the sheet P protrudes downward in the conveyance path between the conveyance drive roller 16 and the conveyance driven roller 17 and the discharge drive roller 19 and the discharge driven roller 20. A bending posture (warping) is formed. Therefore, it is preferable that the restricting portion 32 be provided at a height that can restrict the floating of the paper P in such a posture.

  Specifically, in the present embodiment, the height of the position where the restricting portion 32 contacts the sheet, more specifically, the lowermost end portion of the restricting portion 32 is the nip point between the transport driving roller 16 and the transport driven roller 17, It is below the straight line connecting the nip point between the discharge driving roller 19 and the discharge driven roller 20. Thereby, the sheet floating from the sheet support member 15 can be suppressed satisfactorily.

  The restricting portion 32 may be provided so as to come into contact with the paper P in a state where no paper is lifted, or provided so as not to come into contact with the paper P in a state where no paper is lifted. Also good. From the viewpoint of preventing damage to the recording surface, it is preferable that the restricting portion 32 is provided so as to hardly contact or lightly contact the paper P in a state where the paper does not float.

The restricting portion 32 is formed on the support member 31 in this embodiment. Thereby, compared with the structure which employ | adopts a roller as the control part 32 and attaches a some roller to the several tube support member 31 one by one, the structure which controls paper floating can be obtained at low cost.
In particular, in the present embodiment, since the restricting portion 32 is integrally formed with the tube support member 31 by resin molding, further cost reduction can be achieved.

In the present embodiment, the restricting portion 32 has a convex surface formed on the surface in contact with the paper P as shown in FIGS. Thereby, the contact area between the paper P and the restricting portion 32 can be reduced, and damage when the paper P comes into contact with the restricting portion 32 can be prevented or suppressed.
In order to further prevent damage, it is also preferable to form the restricting portion 32 with a low friction material. Alternatively, a low friction material (tape or the like) may be attached to the surface of the restricting portion 32, or the surface may be subjected to low friction processing by polishing or the like.

  Further, in the present embodiment, a plurality of the restricting portions 32 are provided along the direction (x direction) that intersects the paper transport direction, that is, the paper width direction, so that the paper floating is satisfactorily suppressed over the entire paper width direction. Can do.

  In the present embodiment, a plurality of discharge drive rollers 19 are provided along the paper width direction, and at least a part of the plurality of regulating portions 32 is positioned at the position of the discharge drive roller 19 in the paper width direction as shown in FIG. It is provided corresponding to. It should be noted that being provided corresponding to the position of the discharge drive roller 19 means that the position of the restricting portion 32 in the paper width direction is the same as or substantially the same as the position of the discharge drive roller 19. Further, among the plurality of restricting portions 32, the other ones may be provided at positions deviating from the position of the discharge drive roller 19.

  In FIG. 14, the restricting portion 32 is indicated by a two-dot chain line, and reference numerals 15 a and 15 b indicate ribs provided on the paper support member 15. The ribs 15a and 15b extend in the paper transport direction and are provided at a suitable interval in the paper width direction, and have a function of supporting the paper P from below (see also FIGS. 2 and 15). .

Here, the discharge drive roller 19 is provided at the position of the rib 15a in the paper width direction, and the paper P that has absorbed ink has a crest at the position of the discharge drive roller 19 and the rib 15a and a valley between them. A ring is formed. In other words, the sheet floating is most prominent at the position of the discharge driving roller 19.
However, in this embodiment, since the restricting portion 32 is provided at the position of the discharge drive roller 19 as described above, it is possible to effectively suppress the sheet floating due to cockling.

  As another embodiment, the restricting portion may be configured to be elastically deformable in the sheet floating direction. In FIG. 15 and FIG. 16, reference numeral 33 indicates such a restricting portion, which is elastically deformed as indicated by a change from a solid line (reference numeral 33) to a virtual line (reference numeral 33 ′) in the enlarged view of FIG. 15. The paper P is pushed up. Reference numeral 31 ′ denotes a tube support member provided with the restricting portion 33.

  That is, when the stiffness (rigidity) of the paper P is strong, the paper P may be strongly pressed against the restricting portion, and as a result, scratches or the like may be formed on the recording surface. However, in this aspect, since the restricting portion 33 can be elastically deformed in the floating direction of the paper P, even if the paper P is strong (rigid) as described above, significant damage to the recording surface is caused. The floating can be appropriately suppressed while preventing the above.

By the way, the restricting portion 32 (or restricting portion 33) described above is formed on the tube support member 31, and the tube support member 31 supports the ink tube 12. Thereby, the tube support member 31 receives an external force indicated by an arrow F in FIG.
Thereby, the tube support member 31 is prevented from being deformed in the direction in which the discharge driven roller 20 is separated from the discharge drive roller 19.

  That is, when the tube support member 31 is warped along the paper width direction, the position of the discharge driven roller 20 with respect to the discharge driving roller 19 changes. In particular, when the discharge driven roller 20 is separated from the discharge driving roller 19, There is a possibility that the conveying force is not given to P, resulting in poor discharge. In marginless printing in which recording is performed on the four sides of the paper P without margins, the paper P is transported by the discharge driving roller 19 and the discharge driven roller 20 when recording is performed on the trailing edge of the paper. If the driven roller 20 is separated from the discharge driving roller 19, recording cannot be performed properly. In particular, such warpage of the tube support member 31 may occur not only immediately after resin molding but also with time as the apparatus is used.

  However, as described above, the tube support member 31 receives the external force indicated by the arrow F in FIG. 15 from the ink tube 12, and the deformation in the direction in which the discharge driven roller 20 is separated from the discharge drive roller 19 is suppressed. The paper feeding operation can be maintained. Since the ink tube 12 is used as a means for suppressing the deformation of the tube support member 31, it is possible to achieve both of low cost and prevention of enlargement of the apparatus and appropriate paper feeding operation over a long period of time. it can.

  In this embodiment, as shown in FIGS. 3, 4, 6, 8, and 9, the ink tube 12 extends from the carriage 8 in the first direction (x + direction) that is the moving direction of the carriage. The tube support member 31 supports the previous section bent in the rear downward direction and turned back in the second direction (x-direction) which is the opposite direction to the first direction. Therefore, the tube support member 31 receives a repulsive force from the ink tube 12 accompanying the folding of the folded portion (curved portion) 12 a of the ink tube 12. Thereby, the deformation of the tube support member 31 can be more effectively suppressed as compared with the configuration in which the ink tube 12 is simply supported.

  In this embodiment, at least a part of the ink tube 12 is fixed to the tube support member 31 by the tube fixing member 29, so that the ink tube 12 can be prevented from being violated due to the movement of the carriage 8, and the tube support member 31. Can reliably receive external force from the ink tube 12.

  In the present embodiment, the tube support member 31 includes the tube guide portion 31a that is a guide portion that guides the ink tube 12 in a predetermined direction, so that the ink tube 12 can be guided in an appropriate direction. It is not necessary to provide a separate guide means separately, and the cost can be reduced.

Further, in the present embodiment, the plurality of ink tubes 12 extend on the tube support member 31 in a direction (x direction) intersecting the paper transport direction, and are arranged in parallel along the paper transport direction (y direction). Therefore, the tube support member 31 receives external force over a wide range from the plurality of ink tubes 12. As a result, the deformation of the tube support member 31 in the direction in which the discharge driven roller 20 is separated from the discharge drive roller 19 can be more effectively suppressed.

  Furthermore, in this embodiment, since the guide member 13 that guides the ink tube 12 is provided adjacent to the ink tube 12, the behavior of the ink tube 12 when the ink tube moves as the carriage 8 moves is stable. To do.

  Furthermore, in the present embodiment, as shown in FIGS. 10 and 11, the tube support member 31 is formed with ribs 31 c extending in the direction (longitudinal direction: x direction) intersecting the paper transport direction. Thus, the longitudinal rigidity of the tube support member 31 can be further suppressed.

  The embodiment described above is an example, and it goes without saying that the present invention is not limited to the above embodiment. For example, in the present embodiment, the ink containing portion 6 is provided on the right side surface of the apparatus main body 2 of the printer 1, but may be in the opposite direction. In this case, the extending direction and the folding direction of the ink tube 12 may be the opposite direction to the above-described embodiment, or the apparatus front-rear direction (y direction). The ink storage unit 6 is provided outside the apparatus main body 2, but may be provided inside the apparatus main body 2.
