[0007] First, the present invention will be described in general terms. A recording device according to a first aspect of the present invention for solving the above problems comprises: a head for ejecting ink onto a recording medium; a main body provided with a guide shaft; a carriage on which the head is provided and which is reciprocally movable along the guide shaft; and an ink tube having one end connected to an ink storage portion located in the main body and supplying ink to the head. The carriage has a guided portion supported by the guide shaft; a tube holding portion attached to the guided portion and holding the other end of the ink tube; and a head placement portion attached to the guided portion and on which the head is positioned. The attachment portion to which the tube holding portion is attached to the guided portion has a displacement portion that displaces the tube holding portion relative to the guided portion when an external force exceeding a threshold is applied to the tube holding portion.

[0008] According to this embodiment, the carriage has a guided portion supported by a guide shaft, a tube holding portion attached to the guided portion and holding an ink tube, and a head placement portion attached to the guided portion and where the head is positioned. The attachment portion to which the tube holding portion is attached to the guided portion has a displacement portion to which the tube holding portion is displaced relative to the guided portion when an external force exceeding a threshold is applied to the tube holding portion. Therefore, even if an external force exceeding a threshold is applied to the tube holding portion via an ink tube or the like, the tube holding portion is displaced relative to the guided portion with respect to the displacement portion, thereby preventing the guided portion from being displaced to an unintended state relative to the guide shaft, and preventing the carriage from being displaced to an unintended state relative to the guide shaft.

[0009] A recording device according to a second aspect of the present invention is characterized in that, in the first aspect, the tube holding portion abuts the guided portion at a contact portion with a flat tip, and the contact portion has a curved portion that protrudes in a curved shape between the base end and the tip.

[0010] According to this embodiment, the tube holder contacts the guided portion at a contact portion with a flat tip, and the contact portion has a curved portion that protrudes in a curved shape from the base end to the tip. Therefore, even if an external force below the threshold is applied, the flat tip of the contact portion can effectively suppress displacement of the tube holder relative to the guided portion. Furthermore, if an external force above the threshold is applied, the tube holder can be smoothly displaced relative to the guided portion along the curved portion, thereby suppressing damage to both the guided portion and the tube holder.

[0011] A recording device according to a third aspect of the present invention is characterized in that, in the first or second aspect, the displacement portion includes a shaft member that connects the tube holding portion to the guided portion in a displaceable manner, and an elastic member that exerts an elastic force to prevent the tube holding portion from being displaced relative to the guided portion.

[0012] According to this embodiment, the displacement section includes a shaft member that connects the tube holding section to the guided section in a displaceable manner, and an elastic member that exerts an elastic force to prevent the tube holding section from being displaced relative to the guided section. Therefore, the displacement section can be easily constructed using the shaft member and the elastic member.

[0013] A recording device according to a fourth aspect of the present invention is characterized in that, in the third aspect, the shaft member is displaceable in the extending direction.

[0014] According to this embodiment, the shaft member is displaceable in the extension direction. Therefore, the threshold value of the displacement portion can be set over a wide range.

[0015] A recording device according to a fifth aspect of the present invention is characterized in that, in the fourth aspect, it has a plurality of shaft members, and the displacement of each of the shaft members is different.

[0016] According to this aspect, a plurality of shaft members are provided, and the displacement amount of each shaft member is different. Therefore, when an external force equal to or greater than the threshold value is applied to the tube holding portion, the tube holding portion can be displaced with respect to the guided portion in a particularly preferable state and range.

[0017] The recording apparatus according to the sixth aspect of the present invention is characterized in that, in any one of the third to fifth aspects, a plurality of the elastic members are provided, and the elastic force of each of the elastic members is different.

[0018] According to this aspect, a plurality of elastic members are provided, and the elastic force of each elastic member is different. Therefore, when an external force equal to or greater than the threshold value is applied to the tube holding portion, the tube holding portion can be displaced with respect to the guided portion in a particularly preferable state and range.

[0019] The recording apparatus according to the seventh aspect of the present invention is characterized in that, in the sixth aspect, the tube holding portion has the ink tube passed therethrough from a first direction, and the elastic force of each of the elastic members is stronger in a second elastic member provided on the side opposite to the first direction than in a first elastic member provided on the first direction side.

[0020] According to this aspect, the ink tube is passed through the tube holding portion from the first direction, and the elastic force of each elastic member is stronger in the second elastic member than in the first elastic member provided on the first direction side. By adopting such a configuration, when an external force equal to or greater than the threshold value is applied to the tube holding portion, it is possible to particularly preferably suppress the displacement of the guided portion in an unintended state with respect to the guide shaft, and it is possible to particularly preferably suppress the displacement of the carriage in an unintended state from the guide shaft.

[0021] The recording apparatus according to the eighth aspect of the present invention is characterized in that, in the seventh aspect, the carriage has a plurality of the tube holding portions each holding the ink tube from the first direction.

[0022] According to this embodiment, the carriage has a plurality of tube-holding portions, each of which holds an ink tube from a first direction. With this configuration, in a configuration having a plurality of tube-holding portions, it is particularly effective in suppressing unintended displacement of the guided portion relative to the guide axis, and particularly effective in suppressing unintended displacement of the carriage from the guide axis.

[0023] [Example 1] Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings. First, an overview of the recording device 1 of Embodiment 1 of the present invention will be described with reference to Figure 1. Note that in Figure 1, some components are omitted for clarity. Here, the X-axis direction in the figure is the horizontal direction and is the direction in which the rotation axis of the holding part 2 that holds the roll body R1 in which the recording medium M is wound into a roll extends, the Y-axis direction is the horizontal direction and is the front-to-back direction of the recording device 1 and is perpendicular to the X-axis direction, and the Z-axis direction is the vertical direction. Furthermore, in the following, the direction of the arrow will be considered the + direction, and the direction opposite to the direction of the arrow will be considered the - direction. For example, the vertically upward direction is the +Z direction, the vertically downward direction is the -Z direction, the front of the recording device 1 is the -Y direction, and the rear of the recording device 1 is the +Y direction.

[0024] The recording device 1 of this embodiment includes a holding unit 2 that holds a roll body R1 in which the recording medium M is wound in a roll shape. In the recording device 1 of this embodiment, when the recording medium M is transported in the forward transport direction A1, which is the so-called normal transport direction, the holding unit 2, which has a rotation axis along the X-axis direction, rotates in the rotation direction C1. When the recording medium M is transported in the reverse transport direction A2, which is the opposite direction to the forward transport direction A1, the holding unit 2, which has a rotation axis along the X-axis direction, rotates in the rotation direction C2. In this embodiment, a roll body R1 is used in which the recording surface is to be recorded is wound outwards. However, if a roll body R1 is used in which the recording surface is wound inwards, the holding unit 2 can rotate in the rotation direction C2 to feed out the recording medium M from the roll body R1.

[0025] Furthermore, the recording device 1 of this embodiment is equipped with a platen 3 and a platen 6 as media support sections for supporting the recording medium M. Of these, the platen 6 is a media support section provided at a position facing the head 8, which will be described later. The recording device 1 is also equipped with a transport section for transporting the recording medium M in the forward transport direction A1 and the reverse transport direction A2 along the transport path, which includes a transport roller pair 4 consisting of a drive roller 4A and a driven roller 4B, and a transport roller pair 5 consisting of a drive roller 5A and a driven roller 5B.

[0026] Furthermore, the recording device 1 of this embodiment includes a head 8, which serves as a recording unit and has multiple nozzles positioned opposite the platen 6, from which ink is ejected for recording, and a carriage 7 on which the head 8 is mounted and which is capable of reciprocating in the width direction B. The detailed configuration of the carriage 7 will be described later. In the recording device 1 of this embodiment, the surface of the platen 6 that supports the recording medium M is inclined with respect to the horizontal direction, and the direction of ink ejection from the head 8 is inclined with respect to the vertical direction. However, the embodiment is not limited to this configuration, and the surface of the platen 6 that supports the recording medium M may be horizontal, and the direction of ink ejection from the head 8 may be vertical.

[0027] The recording device 1 of this embodiment has a main body 10 which includes a guide shaft 13 and a platen 6, which will be described later, and an ink storage unit 11 can be housed in the main body 10. One end of an ink tube 12 that supplies ink to the head 8 is connected to the ink storage unit 11 located in the main body 10. The other end of the ink tube 12 is held by a carriage 7 and further connected to the head 8. The other end of the ink tube 12 is held by the carriage 7 in the direction corresponding to the second direction B2 in Figure 3, which will be described later, from the +X direction (the far side of the paper in Figure 1) to the -X direction (the near side of the paper in Figure 1).

[0028] In the recording device 1 of this embodiment, the head 8 can record by ejecting ink from a nozzle (not shown) onto the conveyed recording medium M while reciprocating in the width direction B, which is a direction intersecting the forward transport direction A1 and the reverse transport direction A2. The recording device 1 of this embodiment can form a desired image on the recording medium M by repeatedly transporting the recording medium M in the forward transport direction A1 at a predetermined transport amount, and ejecting ink while moving the head 8 in the width direction B with the recording medium M stopped.

[0029] Furthermore, a cutter 9 is provided downstream of the head 8 in the transport direction A, which moves along the width direction B to cut the recording medium M along the width direction B. However, a configuration without the cutter 9 is also possible.

[0030] As described above, the recording device 1 of this embodiment includes a head 8 that ejects ink onto a recording medium M, and a main body 10 on which a guide shaft 13 is provided. It also includes a carriage 7 on which the head 8 is provided and which can reciprocate along the guide shaft 13. Furthermore, it includes an ink tube 12, one end of which is connected to an ink storage section 11 located in the main body 10, and which supplies ink to the head 8.

[0031] Next, the carriage configuration of the recording device 1 of this embodiment will be described in more detail with reference to Figures 2 to 8. As shown in Figure 2, the carriage 7 of this embodiment has a guided portion 17 supported by a guide shaft 13, a tube holding portion 27 attached to the guided portion 17 and holding the other end of the ink tube 12, and a head placement portion 37 attached to the guided portion 17 and on which the head 8 is positioned. The tube holding portion 27 is attached to the guided portion 17 by a mounting portion 50, and the head placement portion 37 is attached to the guided portion 17 by a spring member 15. In this embodiment, the carriage 7 is configured to be movable by providing the head placement portion 37 and the guided portion 17 separately, and attaching the head placement portion 37 to the guided portion 17 by a spring member 15, but the configuration is not limited to this. For example, the head placement portion 37 and the guided portion 17 may be formed integrally.

[0032] The recording device 1 of this embodiment includes a main shaft 13A and a sub-shaft 13B as guide shafts 13. Both the main shaft 13A and the sub-shaft 13B extend in the width direction B and are fixed at both ends to a frame (not shown) provided on the main body 10. The guided portion 17 is in contact with the main shaft 13A and the sub-shaft 13B, and the sub-shaft 13B is biased by a spring member 14. With this configuration, when an external force is applied to the carriage 7, the entire carriage 7 can rotate in the rotation direction D with the main shaft 13A as the pivot axis.

[0033] However, in a typical configuration of the carriage 7 that allows rotation around the guide shaft 13 as the pivot axis when an external force is applied to the carriage 7, if a strong external force is applied to the carriage 7, the carriage 7 may be displaced in an unintended state, such as detaching from the guide shaft 13. For example, in a configuration in which the carriage 7 is equipped with a tube holding part 27 for holding the ink tube 12, an external force is easily applied to the ink tube 12 as the carriage 7 moves back and forth along the width direction B. When an external force is applied to the ink tube 12, the external force is transmitted to the guided part 17 via the tube holding part 27, and the carriage 7 may be displaced in an unintended state.

[0034] Here, as shown in Figure 8, in the reference example recording device 1, which has a general configuration, the mounting part 500 is firmly fixed by a screw 59 so that the tube holding part 27 does not move relative to the guided part 17. In such a configuration, when an external force is applied to the ink tube 12, the external force is transmitted to the guided part 17 via the tube holding part 27, and the carriage 7 is prone to being displaced in an unintended state, such as the carriage 7 coming off the guide shaft 13.

[0035] On the other hand, in the recording device 1 of this embodiment, the mounting portion 50 to which the tube holding portion 27 is attached to the guided portion 17 has a configuration that includes a displacement portion 51 which displaces the tube holding portion 27 relative to the guided portion 17 when an external force exceeding a threshold is applied to the tube holding portion 27. Specifically, as shown in Figures 4 to 6, the mounting portion 50 has a displacement portion 51 which includes a screw 52, ​​a coil spring 53 passed through the body portion 52B of the screw 52, ​​and a contact portion 54 of the tube holding portion 27 that contacts the guided portion 17. More specifically, the screw 52 has a screw head 52A and a body portion 52B, and the body portion 52B passes through a hole portion 54E provided in the tube holding portion 27 and the body portion 52B is fixed to the guided portion 17, the hole portion 54E is made wider than the body portion 52B and the coil spring 53 is sandwiched between the screw head 52A and the forming portion of the hole portion 54E of the tube holding portion 27.

[0036] In other words, the recording device 1 of this embodiment is configured such that the tube holding part 27 is displaced when a force greater than, for example, the spring force of the coil spring 53 is applied to the tube holding part 27 relative to the body part 52B fixed to the guided part 17. Therefore, when an external force less than the threshold is applied to the tube holding part 27, the displacement part 51 maintains its position without the coil spring 53 being displaced. However, when an external force greater than the threshold is applied to the tube holding part 27, the displacement part 51 causes the coil spring 53 to be displaced, causing the tube holding part 27 to be displaced relative to the guided part 17 with the contact part 54 as the fulcrum.

[0037] Since the recording device 1 of this embodiment is equipped with a mounting part 50 with such a configuration, even if an external force exceeding a threshold is applied to the tube holding part 27 via the ink tube 12 or the like, the tube holding part 27 is displaced relative to the guided part 17 with respect to the displacement part 51, thereby suppressing the application of a strong force to the guided part 17. For this reason, the recording device 1 of this embodiment can suppress the guided part 17 from being displaced to an unintended state relative to the guide shaft 13. And as a result, the recording device 1 of this embodiment can suppress the carriage 7 from being displaced to an unintended state from the guide shaft 13.

[0038] Here, the tube holding portion 27 contacts the guided portion 17 at the contact portion 54. As shown in Figure 6, the tip 54A of the contact portion 54 is flat, and the tip 54A is configured to make surface or line contact with the guided portion 17. Furthermore, as shown in Figures 4 and 6, a curved portion 54C is formed between the base end 54B and the tip 54A of the contact portion 54, protruding in a curved shape. Therefore, even if an external force below the threshold is applied to the tube holding portion 27, the flat tip 54A of the contact portion 54 effectively suppresses displacement of the tube holding portion 27 relative to the guided portion 17. Also, if an external force above the threshold is applied to the tube holding portion 27, the tube holding portion 27 can be smoothly displaced relative to the guided portion 17 along the curved portion 54C, thereby suppressing damage to both the guided portion 17 and the tube holding portion 27.

[0039] In this embodiment, as shown in Figure 5, the curved portion 54C has notches 54D formed on the forward conveying direction A1 side and the reverse conveying direction A2 side. The formation of these notches 54D makes it particularly easy for the tube holding portion 27 to move relative to the guided portion 17 in the direction along the forward conveying direction A1 and the reverse conveying direction A2.

[0040] Furthermore, as shown in Figure 3, the recording device 1 of this embodiment includes a mounting portion 50, with a mounting portion 50A on the first direction B1 side through which the ink tube passes, and a mounting portion 50B on the second direction B2 side opposite to the first direction B1. Here, mounting portions 50A and 50B are formed from the same constituent members. That is, the recording device 1 of this embodiment has displacement portions 51 with the same configuration on both mounting portions 50A and 50B. However, the spring force of the coil spring 53 of the displacement portion 51 of mounting portion 50A and the coil spring 53 of the displacement portion 51 of mounting portion 50B are different. In other words, the recording device 1 of this embodiment has multiple elastic members, and the elastic force of each elastic member is different. By making the elastic force of each of the multiple elastic members different, when an external force exceeding a threshold is applied to the tube holding portion 27, the tube holding portion 27 can be displaced relative to the guided portion 17 in a particularly desirable state and range.

[0041] In detail, the ink tube 12 passes through the tube holding portion 27 from the first direction B1. The spring force (elastic force of each elastic member) of the coil springs 53 of the mounting portions 50A and 50B is configured such that the coil spring 53B, which is the second elastic member and is located at the front of the second direction B2, is stronger than the coil spring 53A, which is the first elastic member and is located at the front of the first direction B1. With this configuration, when an external force exceeding a threshold is applied to the tube holding portion 27, it is particularly effective in suppressing the guided portion 17 from being displaced in an unintended state relative to the guide shaft 13, and particularly effective in suppressing the carriage 7 from being displaced in an unintended state relative to the guide shaft 13.

[0042] Here, as described above, the screw 52 constituting the displacement part 51 has a screw head 52A and a body 52B. That is, the displacement part 51 in this embodiment has a body 52B as a shaft member that connects the tube holding part 27 to the guided part 17 in a displaceable manner, and a coil spring 53 as an elastic member that exerts an elastic force to prevent the tube holding part 27 from being displaced relative to the guided part 17. Thus, it is preferable that the displacement part 51 has a configuration that includes a shaft member that connects the tube holding part 27 to the guided part 17 in a displaceable manner, and an elastic member that exerts an elastic force to prevent the tube holding part 27 from being displaced relative to the guided part 17. This is because the displacement part 51 can be easily constructed using the shaft member and the elastic member. Note that the shaft member may have a different configuration from the body 52B of the screw 52, ​​and the elastic member may have a different configuration from the coil spring 53.

[0043] In particular, a shaft member with a configuration that allows displacement in the extension direction, such as having a damper structure, can be preferably used. This is because such a configuration allows the threshold value of the displacement portion 51 to be set over a wide range.

[0044] Furthermore, as described above, the recording device 1 of this embodiment has multiple mounting parts 50 each equipped with a displacement part 51 having a similar configuration. That is, the recording device 1 of this embodiment has multiple body parts 52B which are shaft members. Here, it is preferable that the amount of displacement of each shaft member is different. By making the amount of displacement of each shaft member different, when an external force exceeding a threshold is applied to the tube holding part 27, the tube holding part 27 can be displaced relative to the guided part 17 in a particularly favorable state and range.

[0045] [Example 2] The recording device 1 of Example 2 will be described below with reference to Figure 7. Note that Figure 7 corresponds to Figure 3 in the recording device 1 of Example 1. Furthermore, the recording device 1 of this example is the same as the recording device 1 of Example 1, except for the configuration described below, and therefore has the same characteristics as the recording device 1 of Example 1. Therefore, in Figure 7, components common to both Example 1 and Example 1 are indicated by the same reference numerals, and detailed explanations are omitted.

[0046] As described above, in the recording device 1 of Embodiment 1, one tube holder 27 was provided on one carriage 7. On the other hand, as shown in Figure 7, in the recording device 1 of this embodiment, two tube holders 27 are provided on one carriage 7: tube holder 27A and tube holder 27B. In addition, the mounting parts 50 include mounting parts 50C, 50D, and 50E, each with a structure similar to that of mounting part 50A. In other words, the recording device 1 of this embodiment also has multiple shaft members, which are body parts 52B.

[0047] Here, the ink tube 12 is passed through both the tube holding portion 27A and the tube holding portion 27B from the first direction B1. The elastic force of the elastic members of the mounting portion 50C, mounting portion 50D, and mounting portion 50E is configured such that the second elastic members, coil springs 53D and 53E, provided on the second direction B2 side, are stronger than the first elastic member, coil spring 53C, provided on the first direction B1 side. With this configuration, when an external force exceeding a threshold is applied to the tube holding portion 27, it is particularly effective in suppressing the guided portion 17 from being displaced in an unintended state relative to the guide shaft 13, and particularly effective in suppressing the carriage 7 from being displaced in an unintended state relative to the guide shaft 13.

[0048] Furthermore, by configuring the carriage 7 in such a way that each has multiple tube-holding sections 27 that hold the ink tube 12 from the first direction B1, it is particularly effective in suppressing unintended displacement of the guided section 17 relative to the guide shaft 13 in a configuration with multiple tube-holding sections 27. And it is particularly effective in suppressing unintended displacement of the carriage 7 relative to the guide shaft 13.

[0049] The present invention is not limited to the embodiments described above, and can be realized in various configurations without departing from its spirit. Furthermore, the technical features in the embodiments corresponding to the technical features in each embodiment described in the summary of the invention can be replaced or combined as appropriate in order to solve some or all of the above-described problems, or to achieve some or all of the above-described effects. In addition, if a technical feature is not described as essential in this specification, it can be deleted as appropriate. [Explanation of Symbols]
