[Technical Field]

[0001] The present disclosure relates to a recording device. [Background technology]

[0002] Patent Document 1 discloses a printer device that includes a lower housing, an upper cover that is connected to the lower housing so that it can be opened and closed, and a buffer member that prevents the upper cover from closing suddenly. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2024-14048 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the printer device described in Patent Document 1, one end of the buffer member is connected to the upper cover and the other end is connected to the lower housing, so when the upper cover is opened, the buffer member remains connected between the upper cover and the lower housing. This raises the risk that the buffer member may interfere with work that requires movement across the width of the printer device. [Means for solving the problem]

[0005] The recording device is equipped with a cover that can be opened and closed relative to the device body, and a buffer section provided on the device body, and the cover abuts against the buffer section during the process of closing the cover, and the buffer section reduces the speed at which the cover closes.

[0007] The recording device 1 of this embodiment will be described below with reference to the drawings. The recording device 1 shown in Fig. 1 is, for example, an inkjet printer that records images such as characters and photographs on a medium M by applying ink, which is an example of a "liquid," to the medium M being conveyed.

[0008] In the drawings shown below, the scale of each component is different from the actual scale in order to make each component large enough to be recognizable. Furthermore, in each drawing, the same components are given the same reference numerals, and redundant explanations are omitted. Furthermore, in each drawing, at least one of the X-axis, Y-axis, and Z-axis is illustrated as necessary as mutually orthogonal coordinate axes. The X-axis, Y-axis, and Z-axis are each indicated by an arrow. For each of the X-axis, Y-axis, and Z-axis, the direction of the arrow indicates the positive direction, and the direction opposite to the arrow indicates the negative direction.

[0009] The X-axis direction is parallel to the installation surface G and corresponds to the width direction of the recording device 1 and the width direction of the medium M. The Y-axis direction is parallel to the installation surface G and corresponds to the front-to-rear direction of the recording device 1. The Z-axis direction is perpendicular to the installation surface G of the recording device 1 and corresponds to the height direction of the recording device 1. In the recording device 1, the direction in which the medium M is transported is illustrated as the transport direction D, and the direction toward the transport direction D is referred to as downstream, and the opposite direction is referred to as upstream.

[0010] The configuration of the recording device 1 will be described with reference to FIGS. 1 to 6. As shown in FIGS. 1 and 2, the recording device 1 includes a device main body 40, and leg frames 7 are attached to the device main body 40 near both ends in the X-axis direction. Casters 13 and adjusters 14 are provided below the leg frames 7. The recording device 1 can be easily moved using the casters 13, and can be suitably installed on an installation surface G using the adjusters 14. As shown in FIG. 2, the recording device 1 also includes a supply unit 2 that holds a roll R1 on the rear side, or the -Y direction side, of the device main body 40. The supply unit 2 supports the roll R1 around which the medium M is wound by clamping the cardboard tube of the roll R1 in the X-axis direction, and supplies the medium M downstream.

[0011] When transporting the medium M in the transport direction D, the supply unit 2 rotates the roll R1 in a rotation direction C. In FIG. 2, the roll R1 is wound so that the first side M1 on which an image is formed faces outward, but if a roll R1 is used that is wound so that the first side M1 faces inward, the supply unit 2 can rotate the roll R1 in the direction opposite to the rotation direction C to feed out the medium M.

[0012] The recording device 1 also has a transport path for the medium M, which includes a medium support unit 3 that supports the medium M. The recording device 1 has, as the medium support unit 3, an upstream medium support unit 3A, a platen 3B, and a downstream medium support unit 3C, from the upstream side to the downstream side in the transport direction D.

[0013] Furthermore, the recording device 1 is provided with a roller pair 8 consisting of a drive roller 8A and a driven roller 8B as a transport section for transporting the medium M in the transport direction D on the transport path. Note that the driving and driven relationship between the drive roller 8A and the driven roller 8B may be reversed.

[0014] Furthermore, the device body 40 of the recording device 1 is provided with a recording unit 4 that ejects liquid ink to record an image on the medium M at a position facing a support surface 3B1, which is the surface of the platen 3B that supports the medium M. The recording unit 4 is provided with a head (not shown) and a carriage (not shown) that is mounted with the head and can move back and forth in the width direction of the medium M. The width direction of the medium M corresponds to the movement direction of the carriage.

[0015] The head is provided with a plurality of nozzles (not shown). A liquid supply path (not shown) composed of a tube or the like is connected to the head, and ink is supplied to the head from a liquid supply device 4A shown in FIG. 1 via the liquid supply path. As shown in FIG. 2, in the recording device 1, the transport direction D on the support surface 3B1 of the platen 3B is the +Y direction. The width direction, which is the movement direction of the recording unit 4, is the direction along the X-axis. The ink ejection direction is the -Z direction.

[0016] With the above-described configuration, the recording unit 4 can form an image by ejecting ink from the nozzles onto the transported medium M while moving back and forth in the width direction, which is a direction intersecting the transport direction D. The recording device 1 can form a desired image on the medium M by repeatedly transporting the medium M in the transport direction D by a predetermined transport amount and ejecting ink while moving the recording unit 4 in the width direction while the medium M is stopped.

[0017] 2, the downstream medium support unit 3C of the medium support unit 3 is provided with a heater 20 as a heating unit for heating the second surface M2 of the medium M opposite the first surface M1. The heater 20 is formed of an electric heating wire or the like, but is not limited to this configuration. In addition to the downstream medium support unit 3C, the upstream medium support unit 3A and the platen 3B may also be provided with a medium heating unit for heating the second surface M2 of the medium M opposite the first surface M1.

[0018] 1, a blower 10 is provided in a portion of the transport path facing the downstream medium support unit 3C, which blows airflow F to dry ink ejected from the recording unit 4 onto the first surface M1 of the medium M. The blower 10 is supported at both ends of the downstream medium support unit 3C in the X-axis direction. As shown in FIG. 2, the blower 10 includes a fan 11 that generates airflow F, and is configured to be able to blow gas as airflow F onto the first surface M1 of the medium M, but is not limited to such a configuration.

[0019] As shown in FIG. 2, downstream of the downstream medium support unit 3C in the conveying direction D, a winding unit 6 is provided that winds up the medium M conveyed in the conveying direction D into a roll to form the winding roll R2. The medium M conveyed from the supply unit 2 to the winding unit 6 is conveyed along the conveying path with a predetermined tension applied. The winding unit 6 supports the paper tube that is the winding core of the winding roll R2 by sandwiching it in the X-axis direction and rotating the paper tube to wind up the medium M into a roll. In FIG. 2, the winding unit 6 rotates the winding roll R2 in the rotation direction C, so that the first surface M1 faces outward. However, the medium M may also be wound up so that the first surface M1 faces inward. In this case, the winding unit 6 rotates the winding roll R2 in the direction opposite to the rotation direction C.

[0020] A guide bar 30 is provided between the downstream medium support unit 3C and the winding unit 6 in the transport direction D. The guide bar 30 has an arc-shaped contact surface 31 when viewed in the width direction of the recording device 1. The guide bar 30 guides the transport of the medium M by contacting the contact surface 31 with the second surface M2 of the medium M being wound around the winding unit 6. There are no particular limitations on the configuration of the guide bar 30, and the configuration may also be such that the guide bar 30 is not provided.

[0021] The device main body 40, which is a main part of the recording device 1, will be described in detail below with reference to FIGS. 2 to 4. As shown in FIGS. 2 and 3, the recording device 1 includes the device main body 40 and a cover 50 that can be opened and closed relative to the device main body 40. The device main body 40 covers the upstream medium support unit 3A, the platen 3B, and the recording unit 4, and has a control unit (not shown). The control unit controls various operations of the recording device 1. There are no particular limitations on the configuration of the control unit, and the control unit may also be an external device such as a computer that can communicate with the recording device 1.

[0022] The cover 50 has a substantially L-shape when viewed in the width direction of the recording device 1, with the top surface of the cover 50 covering part of the upper part of the device body 40 in the +Z direction, and the front surface of the cover 50 covering part of the front part of the device body 40 in the +Y direction. When the cover 50 is closed, a lower end 57 of the front surface of the cover 50 faces the support surface 3B1 of the platen 3B.

[0023] By opening the cover 50, part of the front and part of the top of the device main body 40 are opened. For example, if the medium M supported on the platen 3B experiences a transport failure such as a paper jam, an operator can open the cover 50 and then perform an operation such as removing the jammed medium M. When the cover 50 is opened, a "detection unit" (described later) detects that the cover 50 has been opened, and the control unit controls the carriage not to move while the cover 50 is open.

[0024] The cover 50 is rotatably connected to the device body 40 by multiple hinge units 55, each of which has a built-in torsion coil spring 56. The cover 50 rotates around an axis of the hinge unit 55 that is parallel to the X-axis. The torsion coil spring 56 is an example of a "damper." The hinge unit 55 has spring characteristics that reduce the speed at which the cover 50 falls. In this embodiment, as shown in FIG. 3, the recording device 1 is provided with one hinge unit 55 on each end of the cover 50 in the X-axis direction, but is not limited to this configuration. The device body 40 may be provided with one or more hinge units 55. Note that the hinge units 55 may not necessarily have built-in torsion coil springs 56.

[0025] As shown in FIGS. 2 and 3 , the cover 50 is provided with a plurality of contact portions 51 and a plurality of pressing portions 61. The contact portions 51 and the pressing portions 61 are located at positions that become the upper portion of the cover 50 when the cover 50 is closed, and are provided on a surface that faces the inside of the device body 40. In this embodiment, the pressing portions 61 are convex portions. The device body 40 is provided with a plurality of air dampers 81 and a plurality of pressed portions 71. In this embodiment, the pressed portions 71 are detection sensors. The detection sensors may be mechanical switches such as microswitches or optical sensors. Alternatively, the pressed portions 71 may be arranged on the cover 50, and the pressing portions 61 may be arranged on the device body 40.

[0026] The air dampers 81 absorb the impact received when the cover 50 is closed. The air dampers 81 are an example of a "buffer section." In this embodiment, as shown in FIG. 3 , at least two air dampers 81 are provided at positions facing the abutment sections 51 of the closed cover 50 in a plan view. The abutment sections 51 of the cover 50 abut against the air dampers 81 as the cover 50 is closing. By abutting against the cover 50, the air dampers 81 slow down the speed at which the cover 50 is closing.

[0027] In this embodiment, two air dampers 81 are provided. These are arranged at one end and the other end, which are both ends in the X-axis direction. The X-axis direction corresponds to the intersecting direction that intersects with the transport direction D. In this case, the air damper 81 arranged at one end in the X-axis direction corresponds to the first air damper, and the air damper 81 arranged at the other end in the X-axis direction corresponds to the second air damper. In other words, the multiple air dampers 81 include an air damper 81 arranged at one end in the intersecting direction that intersects with the transport direction D in which the medium M is transported, and an air damper 81 arranged at the other end in the intersecting direction.

[0028] As in this embodiment, it is desirable that the device body 40 include a plurality of air dampers 81. The number of air dampers 81 is not limited to two, and may be three or more. However, even in this case, it is desirable that the device body 40 include an air damper 81 arranged at one end in the intersecting direction and an air damper 81 arranged at the other end.

[0029] Furthermore, the air dampers 81 provided at one end and the other end in the intersecting direction intersecting with the transport direction D are each disposed at a position that avoids the operating area AR of the recording unit 4. The operating area AR is an area in which the recording unit 4 can move by the reciprocating movement of the carriage.

[0030] As shown in Fig. 4, the air damper 81 has a cylinder 83, a piston rod 84 inserted into the cylinder 83, and a compression coil spring 86 that urges the piston rod 84 inside the cylinder 83. The compression coil spring 86 urges the piston rod 84 so that it protrudes from the cylinder 83. The compression coil spring 86 is an example of a "spring." The air damper 81 also has a packing 87.

[0031] 4, an imaginary line L1 indicating the position of the upper surface of device body 40 is indicated by a two-dot chain line. When cover 50 is open, upper end 85 of piston rod 84 is located at a position a predetermined height higher than imaginary line L1 indicating the position of the upper surface of device body 40. Cylinder 83 has a cylindrical shape with its longitudinal direction along the Z-axis direction, and piston rod 84 is formed to be able to reciprocate within cylinder 83 along the longitudinal direction of cylinder 83.

[0032] A gap that allows ventilation is provided between the inner wall located at the upper end of the cylinder 83 and the outer periphery of the piston rod 84. The lower end of the cylinder 83 of the air damper 81 is closed by a bottom in which an air vent 88 is formed.

[0033] Compression coil spring 86 is provided inside cylinder 83, and urges piston rod 84 to protrude from cylinder 83 when the load on piston rod 84 is released. Packing 87 is made of an elastic material such as rubber, and is provided in a groove formed in the lower part of piston rod 84. Packing 87 can separate the inside of cylinder 83 into two spaces, and can slide along the inner wall of cylinder 83.

[0034] The vent hole 88 is a hole through which air flows in and out of the internal space of the cylinder 83, which is located below the packing 87, when the piston rod 84 moves back and forth inside the cylinder 83. The diameter of the vent hole 88 is large enough to absorb the impact that the air damper 81 receives.

[0035] As described above, when the piston rod 84 receives a load and moves toward the inside of the cylinder 83, the air inside the cylinder 83 is exhausted through the air vent 88, thereby mitigating the impact that the air damper 81 receives. Furthermore, when the load that the piston rod 84 receives is released, the piston rod 84 is urged by the compression coil spring 86 to protrude from the cylinder 83. Note that the time required for the piston rod 84 to move from the lower end to the upper end of the cylinder 83 is, for example, about 2 seconds.

[0036] 2 and 3, the device body 40 includes a plurality of holding portions 91 that hold the pressed portion 71 and the air damper 81. Each of the plurality of holding portions 91 holds an air damper 81 provided at one end in a transverse direction intersecting with the conveying direction D in which the medium M is conveyed, and an air damper 81 provided at the other end in the transverse direction, in an area that overlaps with the closed cover 50 in a plan view. In addition, the holding portions 91 provided at one end and the other end in the transverse direction intersecting with the conveying direction D also hold the pressed portion 71.

[0037] Air damper 81 is held by holding portion 91 at a position closer to the end of cover 50 in the +Y direction than pressed portion 71. That is, air damper 81 is held by holding portion 91 at a position farther in the +Y direction from hinge portion 55, which serves as the pivot point for cover 50. When cover 50 comes into contact with air damper 81, the force that air damper 81 receives from cover 50 decreases as the air damper 81 moves farther away from hinge portion 55 in the +Y direction. Therefore, air damper 81 has a relatively small damping force and can be made small and lightweight.

[0038] Furthermore, the further away from the hinge portion 55 in the +Y direction the air damper 81 is, the longer the stroke length of the air damper 81 that moves, so an air damper 81 that has a relatively long time to absorb impact can be used.

[0039] In this embodiment, one each of the contact portion 51, pressing portion 61, pressed portion 71, and air damper 81 is provided at both ends in the intersecting direction intersecting with the conveying direction D. However, the present invention is not limited to this configuration. It is sufficient that one each of the contact portion 51, pressing portion 61, pressed portion 71, and air damper 81 is provided at at least one end in the intersecting direction intersecting with the conveying direction D.

[0040] 4, the holding portion 91 holds the upper portion of the cylinder 83 so that the piston rod 84 protrudes upward and the lower portion of the cylinder 83 protrudes into the device body 40. A guide hole 95 is formed in the holding portion 91. The guide hole 95 is a hole that penetrates in the Z-axis direction.

[0041] 2 and 3, the contact portion 51 and the air damper 81 are provided at positions farther away from the hinge portion 55 in the +Y direction than the pressing portion 61 and the pressed portion 71. The recording device 1 is provided with a plurality of pressing portions 61 and a plurality of pressed portions 71 that detect the opening and closing of the cover 50. The pressing portions 61 and the pressed portions 71 are an example of a "detection portion." The "detection portion" is made up of the pressing portion 61 provided on the cover 50 and the pressed portion 71 provided on the holding portion 91 that detects that the cover 50 is closed by being pressed by the pressing portion 61.

[0042] In the process of closing the cover 50, the pressing portion 61 passes through the guide hole 95 shown in FIG. 4. Having passed through the guide hole 95, the pressing portion 61 presses the pressed portion 71 as shown in FIG. 2. In this way, the "detection portion" detects that the cover 50 is closed. In addition, in the process of opening the cover 50, the pressure between the pressing portion 61 and the pressed portion 71 is released, causing the "detection portion" to detect that the cover 50 is open. In this embodiment, for example, the "detection portion" is configured to detect that the cover 50 is open when the bottom end portion 57 of the closed cover 50 is opened by 2 mm or more.

[0043] As described above, cover 50 has abutment portion 51 that abuts against upper end 85 of piston rod 84 of air damper 81, which is a "buffer portion." The material of piston rod 84, which is the portion that abuts against abutment portion 51, and the material of abutment portion 51 are configured to have different wear resistances. In this embodiment, the material of abutment portion 51 is ABS resin, and the material of piston rod 84 that abuts against abutment portion 51 is POM resin, which has higher wear resistance than abutment portion 51.

[0044] The following describes the operation of opening and closing the cover 50 relative to the device body 40, with the hinge portion 55 as a pivot point, with reference to FIGS. 5 and 6. In FIGS. 5 and 6, an imaginary line L1 indicating the imaginary position of the top surface of the device body 40 and an imaginary line L2 indicating the imaginary position of the support surface 3B1 of the platen 3B are indicated by two-dot chain lines. The cover 50 can be opened to a position where it will not fall under its own weight. When the cover 50 is closed, the hinge portion 55 reduces the speed at which the cover 50 falls. Then, as shown in FIG. 5, the abutment portion 51 abuts against the upper end 85 of the piston rod 84. The closing speed of the cover 50 is further reduced by the abutment of the air damper 81.

[0045] Cover 50 closes under its own weight, while the impact of closing is absorbed by air damper 81. In the process of closing cover 50, pressing portion 61 presses pressed portion 71 after abutting portion 51 provided on cover 50 abuts against upper end 85 of piston rod 84.

[0046] 6, when the cover 50 is closed, the abutting portion 51 and the upper end 85 of the piston rod 84 abut against each other, and the pressing portion 61 presses the pressed portion 71. In this embodiment, the upper surface of the cover 50 is aligned with the upper surface of the device body 40 indicated by the imaginary line L1, but this configuration is not limited to this. In addition, a gap is provided between the lower end 57 of the cover 50 and the imaginary line L2, allowing the medium M to be transported downstream in the transport direction D from the device body 40.

[0047] Even if the cover 50 falls due to its own weight while being opened from a closed state, the piston rod 84 immediately protrudes upward from the cylinder 83 due to the compression coil spring 86. As a result, the cover 50 again comes into contact with the air damper 81 while being closed. The air damper 81 against which the cover 50 comes into contact slows down the speed at which the cover 50 is closed. In other words, even if the cover 50 falls while being opened, the speed at which the cover 50 is closed is reduced, thereby mitigating the impact when the cover 50 is closed.

[0048] As described above, the recording apparatus 1 of this embodiment can provide the following effects. According to this recording device 1, the cover 50 comes into contact with the air damper 81 as the cover 50 is being closed. That is, the cover 50 and the air damper 81 are not connected, which prevents a decrease in the workability of the recording device 1. Furthermore, the air damper 81 reduces the speed at which the cover 50 is closed, which can reduce the impact when the cover 50 is closed.

[0049] According to this recording device 1, the holding portion 91 holds the upper part of the cylinder 83 so that the piston rod 84 protrudes upward and the lower part of the cylinder 83 protrudes into the device body 40, thereby preventing the device body 40 from becoming larger. Furthermore, when the cover 50 is open, the upper end 85 of the piston rod 84 is located at a position that is a predetermined height higher than the upper surface of the device body 40, thereby mitigating the impact when the cover 50 is closed.

[0050] According to this recording device 1, in the process of closing the cover 50, after the cover 50 comes into contact with the upper end 85 of the piston rod 84, the pressing portion 61 provided on the cover 50 presses the pressed portion 71 provided on the holding portion 91. In other words, since the pressing portion 61 presses the pressed portion 71 after the impact when the cover 50 is closed has been alleviated, damage to the pressing portion 61 and the pressed portion 71 can be suppressed.

[0051] According to this recording device 1, the device body 40 is provided with a plurality of air dampers 81, which can further reduce the impact when the cover 50 is closed. In addition, damage to the pressing portion 61 and the pressed portion 71 can also be further suppressed.

[0052] According to this recording device 1, the multiple pressing portions 61 and pressed portions 71 include an air damper 81 provided at one end in the intersecting direction intersecting with the transport direction D in which the medium M is transported, and an air damper 81 provided at the other end in the intersecting direction. This allows for a balanced reduction in the impact when the cover 50 is closed at both ends in the intersecting direction intersecting with the transport direction D in which the medium M is transported. In other words, the cover 50 can be closed in a stable position. Damage to the pressing portions 61 and pressed portions 71 can also be stably prevented.

[0053] According to this recording device 1, the material of the piston rod 84 that contacts the contact portion 51 of the air damper 81 has different wear resistance from the material of the contact portion 51, so that it is possible to reduce wear of the material with higher wear resistance.

[0054] According to this recording device 1, the piston rod 84 that comes into contact with the contact portion 51 is made of POM resin, and the contact portion 51 is made of ABS resin. POM resin is more wear-resistant than ABS resin, and therefore wear on the piston rod 84 can be reduced. In this embodiment, the cylinder 83 is also made of POM resin. Both the cylinder 83 and the piston rod 84 are made of POM resin, which has high wear resistance and lubricity among resins, and therefore the piston rod 84 can smoothly reciprocate inside the cylinder 83.

[0055] According to this recording device 1, the cover 50 is connected to the device body 40 by a hinge part 55 that has a built-in "damper," so that the impact when the cover 50 is closed can be mitigated even before the cover 50 abuts against the air damper 81.

[0056] According to this recording device 1, the air damper 81 is disposed at a position that avoids the operating area AR of the recording unit 4, and therefore the air damper 81 does not adversely affect the operation of the recording unit 4.

[0057] Although the present embodiment has been described in detail above with reference to the drawings, the specific configuration is not limited to the present embodiment, and may be changed, replaced, deleted, etc., without departing from the spirit of the present invention. In addition, other embodiments as described below may also be used.

[0058] In the present embodiment, the contact portion 51 and the air damper 81 are provided at positions farther away from the hinge portion 55 in the +Y direction than the pressing portion 61 and the pressed portion 71, but this is not limiting. The pressing portion 61 and the pressed portion 71 may also be provided at positions farther away from the hinge portion 55 in the +Y direction than the contact portion 51 and the air damper 81. Even in this case, the same effect as in the present embodiment can be obtained. Furthermore, because the pressing portion 61 and the pressed portion 71 are provided at positions farther away from the hinge portion 55 in the +Y direction than the contact portion 51 and the air damper 81, it is possible to detect at an early stage that the cover 50 has been opened.

[0059] In the present embodiment, the upper end 85 of the piston rod 84 is located at a position a predetermined height higher than the imaginary line L1 indicating the position of the top surface of the device body 40 when the cover 50 is open. However, this is not limiting. When the cover 50 is open, the upper end 85 of the piston rod 84 may be at the same height as the imaginary line L1 indicating the position of the top surface of the device body 40, or may be located at a position a predetermined height lower than the imaginary line L1. In this case, by making the abutment portion 51 protrude in the -Z direction, the same effect as in the present embodiment can be obtained. Furthermore, because the piston rod 84 is not located at a position higher than the imaginary line L1 indicating the position of the top surface of the device body 40, a decrease in operability of the recording apparatus 1 can be further suppressed.
