[0008] According to this aspect, the top surface of the housing has an opening / closing section in which a transparent member is arranged, and a metal first plate member constituting the top surface has a holding section that holds the transparent member sandwiched between the upper surface and the lower surface. With this configuration, the transparent member can be arranged on the housing without forming a beam using a metal frame or the like. This prevents overlapping of the transparent member with the beam or the like, which would interfere with visibility, making it easier to check the printing status.

[0009] A second aspect of the printing device of the present invention is an aspect dependent on the first aspect, and is characterized in that the holding portion has a second plate member made of metal and constituting part of the lower surface portion, and the transparent member is sandwiched between the upper surface portion and the second plate member.

[0010] According to this aspect, the holding part has a second plate member made of metal that forms part of the lower surface part, and the transparent member is sandwiched between the upper surface part and the second plate member. This configuration makes it easier to hold the transparent member securely in the holding part, and allows the first opening and the transparent member to be made larger, making it easier to check the printing status in particular.

[0011] A printing device of a third aspect of the present invention is an aspect dependent on the second aspect, characterized in that the holding portion has a third plate member made of metal having a second opening at a position overlapping with the first opening in the support direction, the third plate member is positioned on the other side of the second plate member at a position overlapping with the transparent member, and the second plate member is supported by the third plate member from the other side.

[0012] According to this aspect, the holding portion has a third plate member made of metal, and the second plate member is supported from the other side by the third plate member. Therefore, the second member can be securely supported by the third plate member. Furthermore, the third plate member has a second opening at a position on the other side of the second plate member that overlaps with the transparent member and that overlaps with the first opening in the support direction. Therefore, it is possible to prevent the third plate member from interfering with visibility.

[0013] A printing device of a fourth aspect of the present invention is an aspect dependent on the third aspect, and is characterized in that the opening / closing section has a front cover that forms part of the front surface, which is the surface on the forward side of the housing, and is made of a transparent material, a fourth plate member that is provided at the end of the first plate member in a width direction that intersects with the support direction and the front-to-back direction, and a fifth plate member that is fixed to the second plate member and made of metal, wherein the second plate member has a bending portion that extends along the width direction, the fifth plate member is fixed to the bending portion, and the front cover is fixed to the fourth plate member and the fifth plate member.

[0014] According to this aspect, the opening / closing unit includes a front cover that forms part of the front surface and is made of a transparent material, a fourth plate member that is provided at an end of the first plate member in the width direction, and a fifth plate member that is fixed to the second plate member and is made of metal, and the front cover is fixed to the fourth plate member and the fifth plate member. With this configuration, the user can check the progress of printing through the first opening and can also check the progress of printing from the front side. Furthermore, the front cover can be securely held without interfering with visibility.

[0015] A printing device according to a fifth aspect of the present invention is an aspect dependent on the fourth aspect, and is characterized in that the one end of the front cover is in contact with the third plate member.

[0016] According to this aspect, one end of the front cover in the support direction is in contact with the third plate member. This configuration allows the front cover to be firmly fixed, and prevents the front cover from wobbling when the opening / closing section is opened or closed.

[0017] A printing device of a sixth aspect of the present invention is an aspect dependent on the first or second aspect, and is characterized in that a support shaft is provided at the end of the top surface portion on the rear side in the front-to-rear direction, the top surface portion opens and closes using the support shaft as a fulcrum, and has a convex portion attached to the first plate member between the support shaft and the first opening in the front-to-rear direction, and the apex of the convex portion is in contact with the third plate member.

[0018] According to this aspect, the top surface has a protrusion attached to the first plate member between the support shaft and the first opening in the front-rear direction, and the apex of the protrusion is in contact with the third plate member. This configuration can increase the rigidity of the top surface.

[0019] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. First, an overview of a printing device 1 according to an embodiment of the present invention will be described with reference to FIGS. 1 and 2. Note that in FIG. 1, some components are simplified and omitted to make the configuration easier to understand. In each figure, the X-axis direction in the figure is the horizontal direction and corresponds to the axial direction of a roll R1 on which printing medium M is wound in a roll shape; the Y-axis direction is the horizontal direction and also corresponds to the front-to-rear direction of the printing device 1, perpendicular to the X-axis direction; and the Z-axis direction is the vertical direction. In the following, the direction in which an arrow points is referred to as the + direction, and the direction opposite to the arrow pointing direction is referred to as the - direction. For example, the vertically upward direction is referred to as the +Z direction, the vertically downward direction is referred to as the -Z direction, the front of the printing device 1 is referred to as the +Y direction, and the rear of the printing device 1 is referred to as the -Y direction.

[0020] As shown in Figures 1 and 2, the printing device 1 of this embodiment has a housing 100, and leg frames 7 are attached to the housing 100 near both ends in the X-axis direction. Casters 13 and adjusters 14 are provided below the leg frames 7, and the printing device 1 can be easily moved using the casters 13, and the printing device 1 can be appropriately installed on an installation surface G using the adjusters 14. The printing device 1 of this embodiment also has a supply unit 2 that holds a roll R1 on the rear side, or the -Y direction side, of the housing 100. The supply unit 2 supports the paper tube of the roll R1 around which printing medium M is wound, so as to sandwich it in the X-axis direction, and supplies the printing medium M to a position facing the head 5, which serves as the printing unit.

[0021] In the printing device 1 of this embodiment, when the printing medium M is transported in the transport direction A, the supply unit 2 rotates the roll R1 in a rotation direction C. Note that, although the roll R1 used in FIG. 1 is wound so that the image forming surface M1 on which the image is formed faces outward, if a roll R1 wound so that the image forming surface M1 faces inward is used, the supply unit 2 can rotate the roll R1 in the direction opposite to the rotation direction C to feed out the printing medium M.

[0022] The printing device 1 of this embodiment also has a transport path for the printing medium M, which includes a medium support unit 3 that supports the printing medium M on a support surface. The printing device 1 of this embodiment 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 A.

[0023] The printing device 1 also includes a roller pair 8 consisting of a drive roller 8A and a driven roller 8B as a transport unit for transporting the print medium M in the transport path in the transport direction A. However, there are no particular limitations on the configuration of the transport unit.

[0024] The printing device 1 of this embodiment also includes a head 5, which serves as a printing unit facing the platen 3B and has multiple nozzles that eject liquid ink from the nozzles to form an image, and a carriage 4 that carries the head 5 and is movable back and forth in the width direction B. In other words, the width direction B corresponds to the scanning direction of the carriage. A liquid supply path (not shown) made of a tube or the like is connected to the head 5, and ink is supplied to the head 5 via the liquid supply path from an ink cartridge attached to a liquid supply device 50 shown in FIG. 2. In the printing device 1 of this embodiment, the transport direction A at the position facing the head 5 on the platen 3B is the +Y direction, the width direction B, which is the direction of movement of the head 5, is the direction along the X-axis, and the ink ejection direction is the -Z direction.

[0025] With the above-described configuration, the head 5 can form an image by ejecting ink from nozzles (not shown) onto the transported print medium M while moving back and forth in the width direction B, which is a direction intersecting the transport direction A. The printing device 1 of this embodiment can form a desired image on the print medium M by repeatedly transporting the print medium M in the transport direction A by a predetermined transport amount and ejecting ink while moving the head 5 in the width direction B with the print medium M stopped.

[0026] Furthermore, the downstream medium support section 3C of the medium support section 3 is provided with a heater 20 as a heating section for heating the supported surface M2 of the print medium M on the side opposite the image forming surface M1. In this embodiment, the heater 20 is configured with an electric heating wire or the like, but is not limited to this configuration. Furthermore, in addition to the downstream medium support section 3C, the upstream medium support section 3A and the platen 3B may also be provided with a medium heating section for heating the supported surface M2 of the print medium M on the side opposite the image forming surface M1.

[0027] Additionally, a blower 10 is provided at a portion of the transport path facing the downstream medium support unit 3C, which dries the ink ejected from the head 5 onto the image forming surface M1 of the printing medium M by blowing an airflow F. The blower 10 of this embodiment includes a fan 11 that generates an airflow F, and is configured to be able to blow gas as the airflow F onto the image forming surface M1 of the printing medium M, but is not limited to such a configuration.

[0028] Further, downstream of the downstream medium support unit 3C in the transport direction A, a winding unit 6 is provided. The winding unit 6 winds the printing medium M transported in the transport direction A into a roll to form the roll R2. In the printing device 1 of this embodiment, the supply unit 2 and the winding unit 6 have the same configuration. The printing medium M transported from the supply unit 2 to the winding unit 6 is transported while being applied with a predetermined tension by the winding unit 6 or the like. The winding unit 6 supports the paper tube, which is the winding core of the roll R2, by sandwiching it in the X-axis direction and rotating the paper tube to wind the printing medium M into a roll. In FIG. 1, the winding unit 6 rotates the roll R2 in the rotation direction C so that the image forming surface M1 faces outward. However, the printing medium M may also be wound so that the image forming surface M1 faces inward. In this case, the winding unit 6 rotates the roll R2 in the direction opposite to the rotation direction C.

[0029] A guide bar 200 is provided between the downstream medium support unit 3C and the winding unit 6 in the transport direction A. The guide bar 200 has a contact surface 201 that is arc-shaped when viewed from the width direction B. The guide bar 200 guides the transport of the printing medium M by bringing the contact surface 201 into contact with the supported surface M2 of the printing medium M being wound around the winding unit 6. However, there are no particular limitations on the configuration of the guide bar 200, and the configuration may also be such that the guide bar 200 is not provided.

[0030] As described above, the printing device 1 of this embodiment includes a platen 3B as a support part that supports the printing medium M, a head 5 that forms an image by ejecting liquid onto the printing medium M supported by the platen 3B, and a housing 100 that houses the platen 3B and the head 5. As shown in FIG. 2, the printing device 1 of this embodiment includes a first housing part 110 that covers the top of the platen 3B as the housing 100. Therefore, the first housing part 110 of the housing 100, which is a main part of the printing device 1 of this embodiment, will be described in detail below with reference to FIGS. 3 to 10.

[0031] 3 and 5, the first housing unit 110 has a fixed part 111 and an opening / closing part 112 that can be opened and closed by rotating in rotation directions D1 and D2 around a support shaft 1120 that extends in the X-axis direction relative to the fixed part 111. The opening / closing part 112 is arranged so that a portion of it overlaps with the platen 3B in the support direction of the printing medium M by the platen 3B, which corresponds to the Z-axis direction.

[0032] The opening / closing unit 112 has a top surface 1121 that is part of the top surface of the housing 100 and faces the platen 3B in the support direction of the print medium M. The top surface 1121 has a first plate member 1121b made of metal and having a first opening 1121a, and a transparent member 1123 that is arranged in a position that overlaps with at least the first opening 1121a in the support direction of the print medium M. In other words, the transparent member 1123 is arranged in the first opening 1121a, and the user can view the inside of the housing 100 from the outside through the transparent member 1123.

[0033] 5 and 7, the first plate member 1121b has a holder 1122 for the transparent member 1123 at a front end 1121c, which is the end of the housing 100 on the front side corresponding to the +Y direction in the front-to-rear direction, which is a direction intersecting the support direction of the print medium M and corresponds to the Y-axis direction. The holder 1122 is formed with an upper surface 1122a located on one side (the +Z direction side) in the support direction of the print medium M, a front surface 1122b located on the front side (the +Y direction side), and a lower surface 1122c located on the other side (the -Z direction side) in the support direction of the print medium M. As shown in FIG. 7, the holder 1122 holds the transparent member 1123 sandwiched between the upper surface 1122a and the lower surface 1122c.

[0034] As described above, the printing device 1 of this embodiment has an opening / closing section 112 in which a transparent member 1123 is arranged on the top surface 1121 of the housing 100, and a holding section 1122 that holds the transparent member 1123 sandwiched between an upper surface 1122a and a lower surface 1122c on a first metal plate member 1121b that constitutes the top surface 1121. By adopting such a configuration, the printing device 1 of this embodiment can arrange the transparent member 1123 in the housing 100 without forming a beam using a metal frame or the like. Therefore, the printing device 1 of this embodiment can prevent a part of the transparent member 1123 from overlapping with a beam or the like, which would interfere with visibility, making it easier to check the printing status.

[0035] In the printing device 1 of this embodiment, the front end 1121c of the first plate member 1121b is bent in two stages to form a U-shape when viewed in the X-axis direction, i.e., the front surface 1122b is flat, but the configuration is not limited to this. For example, the front end 1121c of the first plate member 1121b may be bent in one stage into a curved shape to form a U-shape when viewed in the X-axis direction, i.e., the front surface 1122b may be curved.

[0036] More specifically, in the printing device 1 of this embodiment, as shown in Fig. 7 and the like, the holding unit 1122 has a second plate member 1124 made of metal and constituting part of the lower surface portion 1122c. Then, as shown in Fig. 7, the transparent member 1123 is sandwiched between the upper surface portion 1122a and the second plate member 1124. With this configuration, the printing device 1 of this embodiment can easily hold the transparent member 1123 securely in the holding unit 1122, and can configure the first opening 1121a and the transparent member 1123 to have large areas, making it particularly easy to check the printing status.

[0037] In the printing device 1 of this embodiment, the front end portion 1121c of the first plate member 1121b is configured with two members, including the bottom surface portion 1122c and the second plate member 1124, but this configuration is not limited to this. For example, the bottom surface portion 1122c may be configured with only one member by simply bending the front end portion 1121c of the first plate member 1121b.

[0038] 7, the holding unit 1122 of the printing device 1 of this embodiment has a third plate member 1125 on the other side (-Z direction side) of the second plate member 1124 in the support direction of the printing medium M. Here, the third plate member 1125 is made of metal, and has a second opening 1125a at a position overlapping with the transparent member 1123 in the support direction, more specifically, at a position overlapping with the first opening 1121a in the support direction, as shown in FIGS. 4 and 5. This prevents the third plate member from interfering with visibility.

[0039] 7, the second plate member 1124 is supported from the -Z direction side by the third plate member 1125. With this configuration, the printing device 1 of this embodiment can firmly support the second plate member 1124 by the third plate member 1125.

[0040] 3 to 9, the printing device 1 of this embodiment is provided with a front cover 113 formed of a transparent material and forming part of the front surface, which is the surface facing forward of the housing 100, on the opening / closing unit 112. Also, as shown in FIGS. 4 to 6 and 8, the opening / closing unit 112 is provided with an L-shaped fourth plate member 1127 provided at the end of the first plate member 1121b in the width direction B (X-axis direction) that intersects with the support direction (Z-axis direction) and the front-rear direction (Y-axis direction). Furthermore, as shown in FIGS. 7 and 8, the opening / closing unit 112 is provided with a fifth plate member 1126 made of metal and fixed to the second plate member 1124.

[0041] As shown in FIG. 7, the second plate member 1124 has a bent portion 1124a extending along the width direction B. The fifth plate member 1126 is fixed to the bent portion 1124a, and the front cover 113 is fixed to the fourth plate member 1127 with screws in the X-axis direction and to the fifth plate member 1126 with screws in the Y-axis direction. This configuration of the printing device 1 of this embodiment allows the user to check the progress of printing through the first opening 1121a, and also from the front side (+Y direction). Furthermore, the front cover 113 can be securely held without interfering with visibility.

[0042] 7, the front cover 113 is fixed with an end 113a on one side (the +Z direction side) in the support direction of the printing medium M in contact with the third plate member 1125. With this configuration, the printing device 1 of this embodiment can firmly fix the front cover 113, and can prevent the front cover 113 from wobbling when the opening / closing part 112 is opened or closed.

[0043] 10 , the printing device 1 of this embodiment has a support shaft 1120 at an end 1121d of the top surface 1121 of the opening / closing unit 112 on the rear side (−Y direction side) in the front-to-rear direction. The top surface 1121 of the opening / closing unit 112 rotates in rotation directions D1 and D2 around the support shaft 1120 as a fulcrum to open and close. The top surface 1121 has a protrusion 1128 attached to the first plate member 1121b and protruding in the −Z direction between the support shaft 1120 and the first opening 1121a in the front-to-rear direction (Y axis). The vertex 1128a of the protrusion 1128 is in contact with the third plate member 1125. This configuration of the printing device 1 of this embodiment increases the rigidity of the top surface 1121.

[0044] In the printing device 1 of this embodiment, the convex portion 1128 is rail-shaped and extends along the X-axis, as shown in Fig. 4. However, the present invention is not limited to this configuration. For example, the configuration may be such that multiple convex portions are arranged along the X-axis.

[0045] The present invention is not limited to the above-described embodiments, and can be realized in various configurations without departing from the spirit of the present invention. Furthermore, the technical features in the embodiments corresponding to the technical features in each aspect described in the Summary of the Invention section can be appropriately replaced or combined to solve some or all of the above-described problems or achieve some or all of the above-described effects.
