JP, 2013-132763, A

The ink tube and the FFC are deformed following the movement of the carriage, whereby the binding member is also displaced. With such a displacement operation of the binding member, the binding member may collide with a component (for example, a frame) in the apparatus to generate an offensive collision noise. In particular, when the carriage moves at high speed, the above collision noise becomes more noticeable.
Accordingly, the present invention has been made in view of such a situation, and an object thereof is to provide a recording apparatus which suppresses the collision noise and is excellent in quietness.

  A recording apparatus according to a first aspect of the present invention for solving the above problems includes a recording head for recording on a medium, and a first direction which is a direction intersecting the medium conveyance direction and the first direction A carriage moving in a second direction which is the opposite direction to the carriage, and a member connected to the carriage, which forms a curved reversing portion which curves and reverses, and which deforms with movement of the carriage Member, a flexible holding member provided along the flexible member and suppressing sagging of the flexible member, and a relative relationship between the flexible member and the holding member in the vertical direction And a restricting member for restricting movement, wherein the restricting member is formed of a sheet material and has a deformable form.

  According to this aspect, in the configuration provided with the flexible member and the holding member that suppresses the sag of the flexible member, the relative movement of the flexible member and the holding member in the vertical direction is performed. Since the regulating member for regulating is formed of a sheet material and has a deformable form, the regulating member is excellent in elasticity, whereby the regulating member is a component in the apparatus according to the movement operation of the carriage (as an example, Even if the vehicle collides with the frame), the collision sound is suppressed, and a recording apparatus excellent in noise reduction can be configured.

  According to a second aspect of the present invention, in the first aspect, the restriction member is formed with a long hole extending in a direction intersecting the moving direction of the carriage, and the holding member is passed through the long hole.

  According to the aspect, the relative movement in the vertical direction between the flexible member and the holding member is restricted by the long hole, and the holding member and the restriction member can be movable through the long hole. Since relative displacement is possible in the extending direction of the flexible member, it is possible to allow relative movement between the holding member and the regulating member due to the circumferential length difference between the flexible member and the holding member. The form of the flexible member and the holding member can be naturally maintained.

According to a third aspect of the present invention, in the second aspect, the upper end of the elongated hole is formed in an arc shape.
According to this aspect, since the upper end of the elongated hole is formed in an arc shape, the flexible member and the holding member are produced due to the circumferential length difference between the flexible member and the holding member. It is possible to avoid that the wear in the elongated hole when the relative movement moves is concentrated at the corner portion in the elongated hole, and the wear of the regulating member can be suppressed, and the configuration can be made excellent in durability.

  In a fourth aspect of the present invention according to any one of the first to third aspects, the restriction member is provided with a bent and raised portion, and the bent and raised portion is fixed to the flexible member. It is characterized by

As a result, rubbing between the flexible member and the regulating member can be avoided, and wear of the flexible member or the regulating member can be avoided.

  According to a sixth aspect of the present invention, in any one of the first to fifth aspects, the holding member is formed of a sheet material, and the sheet material constituting the regulating member is a sheet constituting the holding member. It is characterized in that it is thinner than the thickness of the material.

When the medium feed port cover 20 is turned to the −Y direction side and opened, the medium can be supplied to the inside of the apparatus main body 12.

  In the present embodiment, as one example, the ink storage portion 22 is disposed at the + Y direction side end of the −X direction side end of the apparatus main body 12. The ink storage portion 22 is configured to be capable of storing at least one color of ink, for example. For example, the ink storage unit 22 of the model compatible with monochrome printing stores black ink, and the ink storage unit 22 of the model compatible with color printing stores magenta, yellow, and cyan color inks in addition to black ink. It is configured to

  A carriage 24 is provided in the apparatus body 12. Below the carriage 24 is provided a recording head 26 for discharging ink toward the medium. The carriage 24 is configured to be movable in the + X axis direction, which is the first direction, and the −X axis direction, which is the second direction.

  In the present embodiment, the carriage 24 and the ink storage portion 22 are connected by an ink tube 28 which is an example of at least one or more “flexible members” described later. The ink tube 28 can pass ink, which is an example of a liquid, and has flexibility. The ink tube 28 supplies the ink stored in the ink storage unit 22 to the recording head 26 of the carriage 24. In the present embodiment, as shown in FIG. 2, the plurality of ink tubes 28 are arranged along the Z-axis direction which is the vertical direction.

  An example of a medium transport path in the printer 10 will be described with reference to FIG. On the -Y direction side of the apparatus main body 12, a medium support unit 30 for supporting the medium in an inclined posture is provided. As an example, the medium support unit 30 is configured as a hopper. In the present embodiment, the medium support unit 30 is configured to be swingable in a direction in contact with a feed roller 32 described later, and when feeding the medium, the medium support portion 30 swings in a direction approaching the feed roller 32 to feed the medium. In the non-operating state, that is, in the standby state, it is located at a position separated from the feeding roller 32 (see FIG. 2). The medium support unit 30 is provided with an edge guide 34 for guiding the side of the medium set on the support surface 30 a of the medium support unit 30.

<<< Regarding holding member and regulating member >>>
As shown in FIG. 1, at least one ink tube 28 extended from the ink containing portion 22 extends in the + X axis direction, and then curves in the −Y direction to form a curved inversion portion 44. The ink tube 28 is connected to the carriage 24 with the direction in which the ink tube 28 extends from the + X direction side changed from the + X direction side to the −X direction side.

  A holding member 46 is provided along the path of the ink tube 28 from the ink storage portion 22 to the carriage 24 on the outer peripheral side of the path of the ink tube 28 (the outer peripheral side of the ink tube 28 in the curved inversion portion 44). The holding member 46 is formed of, for example, a sheet material made of a resin material, and has flexibility.

As shown in FIG. 3, the holding member 46 is passed through the regulating member 48. The restriction member 48 is formed of, for example, a sheet material made of a resin material, and has flexibility. In the present embodiment, the thickness of the sheet forming the restriction member 48 is thinner than the thickness of the sheet forming the holding member 46.
The restriction member 48 is formed with a plurality of elongated holes 50A, 50B, 50C, and 50D. In the present embodiment, the long holes 50A, 50B, 50C, 50D extend in the Z axis direction which is a direction intersecting the X axis which is the moving direction of the carriage 24. Arc-shaped arc portions 52 are formed at the upper end and the lower end of the long holes 50A, 50B, 50C, 50D, as an example.

  In FIG. 3, the long holes 50A and the long holes 50B are arranged side by side at the + X axial direction end of the regulating member 48, and the long holes 50C and the long holes 50D are arranged side by side at the −X axial direction side. . In the following description, the + Y direction side (inner side) of the regulating member 48 is the inner peripheral side of the holding member 46, and the −Y direction side (outer side) is the outer peripheral side.

  In the present embodiment, the sheet-like holding member 46 is passed through the long holes 50A, 50B, 50C, and 50D in the order from the + X axial direction side to the −X axial direction side in the regulating member 48. Specifically, the holding member 46 is passed through the long hole 50A from the -Y direction side (outside) of the restriction member 48, passes through the + Y direction side (inner side) of the restriction member 48, and is passed through the long hole 50B. It is missing in the -Y direction side of 48. Further, as it is, the holding member 46 extends in the −X direction side, passes from the −Y direction side of the restricting member 48 through the long hole 50 C, and passes out in the + Y direction side of the restricting member 48. Further, the holding member 46 is passed through the long hole 50D through the + Y direction side of the restricting member 48, is pulled out to the -Y direction side of the restricting member 48, and extends in the -X direction.

  Therefore, since the restriction member 48 is alternately passed through the holding members 46 in the long holes 50A, 50B, 50C, 50D, the restriction members 48 are configured to be movable relative to the holding member 46 in the X-axis direction.

  In the restriction member 48, a bent and raised portion 54 is formed between the long hole 50B and the long hole 50C in the X-axis direction. The bent and raised portion 54 is formed in a rectangular shape as an example, and cuts are made in three sides of the rectangular shape in the restriction member 48, and bending and raised from the restriction member 48 with one side not having a cut made as an axis. In the present embodiment, the through-bore 54 a of the number corresponding to the number of the ink tubes 28 is formed in the bent and raised portion 54. An ink tube 28 is passed through the through hole 54 a of the bent and raised portion 54 bent and raised from the regulating member 48. In the present embodiment, the bent and raised portion 54 is fixed to the ink tube 28 as an example. That is, the ink tube 28 and the regulating member 48 do not move relative to each other.

  In the present embodiment, the ink tube 28 is held by the holding member 46 via the bending portion 54 of the regulating member 48. Thereby, the ink tube 28 is held by the holding member 46, and it is possible to suppress the sag in the Z-axis direction. Here, the holding member 46 is passed through the long holes 50A, 50B, 50C, and 50D of the restriction member 48. Therefore, the restricting member 48 is configured to be movable relative to the longitudinal direction (X-axis direction) of the holding member 46.

  On the other hand, since the holding member 46 is passed through the long holes 50A, 50B, 50C, and 50D, the vertical direction is limited within the range of the length of the long holes 50A, 50B, 50C, and 50D in the Z-axis direction. Although relative movement is possible with respect to the Z axis direction), conversely, relative movement between the holding member 46 and the regulating member 48 in the Z axis direction is restricted.

  The relationship between the ink tube 28, the holding member 46, and the restricting member 48 accompanying the movement of the carriage 24 in the X-axis direction will be described with reference to the upper and lower views of FIGS. In the upper view of FIG. 4, the mounting position of the regulating member 48 in the ink tube 28 is located closer to the carriage 24 than the curved reversing portion 44 in the path of the ink tube 28. In this position, the restricting member 48 extends in the X-axis direction.

  Here, as shown in the lower drawing of FIG. 4, when the carriage 24 moves from the position shown in the upper drawing of FIG. 4 to the + X axis direction side, the ink tube 28 and the holding member 46 follow deformation and curve inversion The portion 44 approaches the carriage 24.

At this time, since the restricting member 48 is fixed to the ink tube 28, the restricting member 48 enters the curved inversion portion 44. Here, since the restricting member 48 is formed of a sheet material and can be deformed, the attachment position of the restricting member 48 in the ink tube 28 corresponds to the following deformation of the ink tube 28 as shown in the lower view of FIG. When it approaches to the curve inversion part 44 by this, the control member 48 curves and deforms along the curve inversion part 44. As shown in FIG.
In other words, the restricting member 48 is deformed along with the following deformation of the ink tube 28 due to the movement of the carriage 24.

  As shown in FIG. 5, when the carriage 24 further moves in the + X-axis direction from the lower view of FIG. 4, the curved inversion portion 44 comes closer to the carriage 24 due to the following deformation of the ink tube 28. In this state, the attachment position of the regulating member 48 in the ink tube 28 is located on the side farther from the carriage 24 than the curved inversion portion 44 in the path of the ink tube 28, that is, closer to the ink storage portion 22. Then, when the restricting member 48 moves to a position out of the curve inverting portion 44, the bent and deformed state of the restricting member 48 is eliminated, and the state returns to the state of extending along the X-axis direction.

  Since the restricting member 48 in the present embodiment is formed as a flexible sheet-like member, the restricting member 48 also deforms in response to the deformation of the ink tube 28 and the holding member 46 due to the movement of the carriage 24. Thereby, since the control member 48 deforms smoothly between the state where it extends along the X-axis direction and the state where it is curved and deformed, it is possible to suppress the following deformation of the ink tube 28, and it is possible to move the carriage 24. It can be done smoothly. Furthermore, when the ink tube 28 and the holding member 46 follow and deform due to the movement of the carriage 24, the restricting member 48 can make the holding of the ink tube 28 of the holding member 46 more reliable.

  Furthermore, since the regulating member 48 has elasticity, when the ink tube 28 follows and deforms due to the movement of the carriage 24, even if the regulating member 48 contacts a component in the apparatus body 12, for example, the frame, the elasticity Thus, the force of the collision between the restricting member 48 and the frame is relieved, and the collision sound is suppressed. As a result, when the carriage 24 moves, the noise reduction can be further enhanced.

  In the present embodiment, as shown in FIG. 4, the holding member 46 is located outside the ink tube 28 in the bending and inverting portion 44. When the ink tube 28 and the holding member 46 follow and deform due to the movement of the carriage 24, a circumferential length difference is generated between the ink tube 28 and the holding member 46 at the curved inversion portion 44. Specifically, in the same way as the phenomenon known as so-called inner ring difference, since the holding member 46 passes through the outside in the curved inversion portion 44 and the ink tube 28 passes through the inner side, the circumferential length of the holding member 46 in the curved inversion portion 44 Is longer than the circumferential length of the ink tube 28.

  Here, in the case where the regulating member 48 is fixed to the ink tube 28 and the holding member 46, when the regulating member 48 approaches the curved inversion portion 44 with the movement of the carriage 24, the holding member by the regulating member 48 The circumferential length difference between 46 and the ink tube 28 is not acceptable. As a result, the following deformation of the holding member 46 and the ink tube 28 can not be smoothly performed, and the holding member 46 or the ink tube 28 unnaturally deforms, which affects the movement of the carriage 24 and deteriorates the recording quality. It may lead to

  In the present embodiment, since the regulating member 48 to which the ink tube 28 is fixed is movable relative to the holding member 46, the circumferential length difference between the holding member 46 and the ink tube 28 is allowed. As a result, the form at the time of following deformation of the ink tube 28 and the holding member 46, specifically, the degree of curvature (curvature) at the time of bending and deformation can be made into a state where there is no unreasonableness. As a result, it is possible to maintain the recording quality without affecting the movement of the carriage 24.

  When the holding member 46 and the regulating member 48 move relative to each other due to the circumferential length difference between the ink tube 28 and the holding member 46, the upper and lower ends of the holding member 46 are elongated holes 50A, 50B of the regulating member 48. , 50C, 50D may be in contact with the upper and lower ends. At this time, when corner portions are formed at the upper end and the lower end of the long holes 50A, 50B, 50C, 50D, the wear due to the relative movement of the holding member 46 and the regulating member 48 is concentrated. In the present embodiment, since the circular arc portion 52 is formed at the upper end and the lower end of the long holes 50A, 50B, 50C, 50D, concentration of wear can be suppressed. As a result, wear and tear of the regulating member 48 can be suppressed.

  In the present embodiment, since the regulating member 48 and the holding member 46 are formed of sheet-like members, they can be configured inexpensively. In addition, the weight of the regulating member 48 can be reduced. As a result, when the holding member 46 holds the ink tube 28 via the regulating member 48, it is possible to suppress the ink tube 28 from hanging down with respect to the holding member 46 due to its weight.

  In summary, the printer 10 is provided with the recording head 26 for recording on the medium, and in the + X axis direction which is a direction crossing the Y axis direction and in the −X axis direction which is the opposite direction to the + X axis direction. A moving carriage 24 and a member connected to the carriage 24, which forms a curved inversion portion 44 that bends and reverses, and an ink tube 28 that deforms along with the movement of the carriage 24, and along the ink tube 28 A flexible holding member 46 is provided, which suppresses drooping of the ink tube 28, and a regulating member 48 which regulates the relative movement of the ink tube 28 and the holding member 46 in the Z-axis direction. The regulating member 48 is formed of a sheet material, and has a form that can be deformed with the deformation of the ink tube 28 and the holding member 46.

  According to the above configuration, in the configuration provided with the ink tube 28 and the holding member 46 that suppresses the sagging of the ink tube 28, the restriction member that restricts the relative movement of the ink tube 28 and the holding member 46 in the Z axis direction The restriction member 48 is excellent in elasticity because it is formed of a sheet material and has a form which can be deformed with the deformation of the ink tube 28 and the holding member 46. As a result, even if the restriction member 48 collides with a component (for example, a frame) in the apparatus as the carriage 24 moves, the collision sound is suppressed, and the printer 10 excellent in quietness can be configured.

  The restricting member 48 is formed with elongated holes 50A, 50B, 50C, 50D extending in the Z-axis direction which is a direction intersecting the X-axis direction which is the moving direction of the carriage 24, and the holding member 46 is formed with the elongated holes 50A, 50B, The holding member 46 and the regulating member 48 are relatively displaceable in the extending direction of the ink tube 28 through the long holes 50A, 50B, 50C, 50D.

  According to the above configuration, the relative movement of the ink tube 28 and the holding member 46 in the Z-axis direction is restricted by the long holes 50A, 50B, 50C, 50D, and through the long holes 50A, 50B, 50C, 50D. Since the holding member 46 and the restricting member 48 are relatively displaceable in the extending direction of the ink tube 28, the relative relationship between the holding member 46 and the restricting member 48 resulting from the circumferential length difference between the ink tube 28 and the holding member 46 Movement can be permitted, and the form of the ink tube 28 and the holding member 46 can be naturally maintained.

  The upper ends of the long holes 50A, 50B, 50C, and 50D are formed as a circular arc portion 52 having a circular arc shape. According to this configuration, the wear in the long holes 50A, 50B, 50C, 50D when the ink tube 28 and the holding member 46 move relative to each other due to the circumferential length difference between the ink tube 28 and the holding member 46 is It is possible to avoid concentration on the corner portions in the long holes 50A, 50B, 50C, 50D, to suppress the wear and tear of the regulating member 48, and to have a configuration excellent in durability.

  The restricting member 48 is provided with a bent and raised portion 54, and the bent and raised portion 54 is fixed to the ink tube 28. According to this configuration, the regulating member 48 can be fixed to the ink tube 28 with a simple structure.

  The holding member 46 is formed of a sheet material, and the thickness of the sheet material constituting the regulating member 48 is thinner than the thickness of the sheet material constituting the holding member 46. According to this configuration, the restricting member 48 can follow the deformation of the holding member 46 favorably.

  The ink tube 28 is a tube for supplying the ink to the recording head 26, and a plurality of the ink tubes 28 are arranged along the Z-axis direction.

<<< Modification of the embodiment >>>
(1) In the present embodiment, the regulation member 48 is directly fixed to the ink tube 28 by passing the ink tube 28 through the through hole 54 a of the bent and raised portion 54, but in addition to this, the ink tube 28 and A shock absorbing material may be provided between the through holes 54a. Thereby, the rubbing between the ink tube 28 and the regulating member 48 can be reduced, and the wear of the ink tube 28 or the regulating member 48 can be avoided.

That is, in the embodiment described above, the regulating member 48 is fixed to the ink tube 28 by passing the ink tube 28 through the through hole 54a of the bent and raised portion 54, but in the present embodiment, the through hole is formed as shown in FIG. A window 60 is formed instead of 54a. In FIG. 6, the window hole 60 is formed in the bent and raised portion 58. The other configuration of the restricting member 56 is the same as that of FIG.

  In the present modification, the window hole 60 is set to a size that allows a plurality of ink tubes 28 connected to the carriage 24 to pass through with a sufficient margin. As an example, an elastic member 62 is attached around the window hole 60 of the bent and raised portion 58. The ink tube 28 is passed through the elastic member 62 and fixed. That is, the regulating member 56 is fixed to the ink tube 28 via the elastic member 62. The elastic member 62 can be formed of, for example, foam rubber or the like.

  A window 60 is formed in the bent and raised portion 58, and the ink tube 28 is passed through the window 60, and the bent and raised portion 58 is fixed to the ink tube 28 via the elastic member 62.
