[Modes for carrying out the invention]

[0007] First, the present invention will be described in general terms. A printing apparatus according to a first aspect of the present invention for solving the above problems comprises a printing unit for printing on a medium, a housing for housing the printing unit, an opening / closing cover for opening and closing a part of the housing, and an operation panel provided in a direction parallel to the opening / closing cover when the opening / closing cover is closed, wherein the opening / closing cover has a first wall which is a part of the wall on the first direction side of the housing and a second wall which is a part of the wall on the second direction side that intersects the first wall of the housing, and opens and closes by rotating on a pivot shaft provided on the first wall and extending in the direction parallel, and the inner surface of the second wall of the opening / closing cover is provided with a contact portion which, when the opening / closing cover is closed, contacts a contacted portion provided on a part of the housing or inside the housing, thereby displacing the opening / closing cover so as to move it away from the operation panel.

[0008] According to this embodiment, the opening / closing cover is provided with a contact portion that, when the opening / closing cover is closed, contacts the contact portion, thereby displacing the opening / closing cover away from the operation panel. Therefore, when closing the opening / closing cover, it is possible to prevent the opening / closing cover, which is provided alongside the operation panel, from contacting the operation panel.

[0009] A printing apparatus according to a second aspect of the present invention is an aspect dependent on the first aspect, characterized in that the wall of the housing on the second direction side has an opening that extends beyond the position of the printing section in the direction opposite to the first direction, and the opening / closing cover is configured to cover the opening.

[0010] According to this embodiment, the wall on the second direction side of the housing has an opening that extends beyond the position of the printing section in the direction opposite to the first direction. By having an opening of this configuration, the opening can be made larger, and the efficiency of work performed by opening the opening / closing cover can be improved. Furthermore, the opening / closing cover is configured to be able to cover the opening. Opening / closing covers of this configuration are generally large and prone to twisting, but by providing a contact part on the opening / closing cover that displaces the opening / closing cover away from the operation panel when the opening / closing cover is closed, it is possible to prevent the opening / closing cover, which is provided next to the operation panel, from coming into contact with the operation panel when the opening / closing cover is closed.

[0011] A printing apparatus according to a third aspect of the present invention is an aspect dependent on the first aspect, characterized in that the opening and closing cover is made of resin.

[0012] According to this embodiment, the opening and closing cover is made of resin. This configuration makes the opening and closing cover lightweight and improves the efficiency of work performed when the cover is opened. Although an opening and closing cover with such a configuration is generally prone to twisting, the opening and closing cover is provided with a contact part that, when the opening and closing cover is closed, contact with the operating panel is prevented when the opening and closing cover is closed, as the opening and closing cover is provided alongside the operating panel.

[0013] A printing apparatus according to a fourth aspect of the present invention is an aspect dependent on the first aspect, characterized in that the second wall is thinner in the second portion further from the first wall than in the first portion closer to the first wall.

[0014] In this embodiment, the second wall is thinner in the second portion that is further from the first wall than in the first portion that is closer to the first wall. This configuration makes it easier to open and close the opening / closing cover.

[0015] The printing apparatus according to the fifth aspect of the present invention is an aspect dependent on the first aspect, wherein the contact portion is a protruding portion that protrudes in a direction toward the contacted portion when the opening / closing cover is closed.

[0016] According to this aspect, the contact portion is a protruding portion that protrudes in a direction toward the contacted portion when the opening / closing cover is closed. By adopting such a configuration, the contact portion can be easily configured.

[0017] The printing apparatus according to the sixth aspect of the present invention is an aspect dependent on the fifth aspect, wherein the protruding portion is a plate-like portion that extends in a tangential direction of an arc centered on the rotation axis.

[0018] According to this aspect, the protruding portion is a plate-like portion that extends in a tangential direction of an arc centered on the rotation axis. By adopting such a configuration, when the opening / closing cover is closed, the contact portion and the contacted portion can be brought into contact with high accuracy. Therefore, when the opening / closing cover is closed, it is possible to particularly effectively suppress the opening / closing cover provided beside the operation panel from contacting the operation panel.

[0019] The printing apparatus according to the seventh aspect of the present invention is an aspect dependent on the sixth aspect, wherein an end portion of the plate-like portion in the tangential direction has a tapered shape.

[0020] According to this aspect, the end portion of the plate-like portion in the tangential direction has a tapered shape. By adopting such a configuration, it is possible to suppress the occurrence of snagging between the contact portion and the contacted portion when the contact portion and the contacted portion come into contact with each other as the opening / closing cover is closed. Therefore, it is possible to suppress the occurrence of malfunctions in the opening / closing of the opening / closing cover.

[0021] The printing apparatus according to the eighth aspect of the present invention is an aspect dependent on the first aspect, and includes a maintenance unit, wherein the opening / closing cover covers the maintenance unit in a closed state.

[0022] According to this embodiment, a maintenance unit is provided. With this configuration, the printing apparatus can be kept in a suitable condition. In addition, the opening / closing cover covers the maintenance unit when closed. With this configuration, by making the opening / closing cover a maintenance cover, it is conceivable to enlarge the opening / closing cover to facilitate maintenance work. However, even if the opening / closing cover is enlarged, the opening / closing cover is provided with a contact part that, when the opening / closing cover is closed, contact with the operating panel is suppressed as the opening / closing cover, which is provided next to the operating panel, comes into contact with the operating panel when the opening / closing cover is closed.

[0023] A printing apparatus according to a ninth aspect of the present invention is an aspect dependent on the first aspect, characterized in that the second wall is provided on the opposite side from the operation panel in the direction of arrangement.

[0024] According to this embodiment, the second wall is provided on the opposite side from the operation panel in the direction of alignment. With this configuration, when closing the opening / closing cover, it is particularly effective in preventing the opening / closing cover, which is provided alongside the operation panel, from coming into contact with the operation panel.

[0025] Embodiments of the present invention will be specifically described below with reference to the drawings. In each figure, the X-axis direction is horizontal and corresponds to the width of the printing device 1, the Y-axis direction is horizontal and corresponds to the front-to-back direction of the printing device 1 and is perpendicular to the X-axis direction, and the Z-axis direction is vertical. In the following, the direction in which the arrow points will be considered the + direction, and the direction opposite to the direction in which the arrow points 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 direction of the printing device 1 is the +Y direction, and the back direction of the printing device 1 is the -Y direction.

[0026] As shown in Figure 1, the printing apparatus 1 of this embodiment includes a housing 100, and leg frames 7 are attached to the vicinity of both ends of the housing 100 in the X-axis direction. Casters 13 are provided below the leg frames 7, and the printing apparatus 1 can be easily moved using the casters 13. The printing apparatus 1 of this embodiment also includes a media supply unit (not shown) that holds a rolled medium inside the housing 100. The media supply unit supplies the medium to a position facing the ink ejection surface 5A of the head 5, which is the printing unit.

[0027] Furthermore, at the point where the wall 100A on the first direction side (+Z direction side) of the housing 100, the wall 100B on the second direction side (-X direction side) of the housing 100, and the wall 100C on the third direction side (+Y direction side) of the housing 100 are connected, an opening / closing cover 200 is provided, which constitutes part of wall 100A and part of wall 100B. The configuration of the opening / closing cover 200 and the configuration of the inside of the opening / closing cover 200 will be described later. In addition, an operation panel 300 is provided near the opening / closing cover 200, and the operating surface of the operation panel 300 and wall 100A are located at approximately the same height. The operating surface of the operation panel 300 is mainly oriented in the +Z direction, but the orientation of the operating surface may be changed. Note that the operation panel 300 in this embodiment is a display device equipped with a touch panel. Therefore, the operating surface of the operation panel 300 is also a display surface, and various information is displayed on it.

[0028] The printing apparatus 1 of this embodiment includes a head 5, which is a printing unit that forms an image by ejecting liquid ink from an ink ejection surface 5A provided with a plurality of nozzles, and a carriage 4 on which the head 5 is mounted and which is capable of reciprocating movement in the width direction B. That is, the width direction B corresponds to the scanning direction of the carriage 4. A liquid supply passage (not shown), consisting of a tube or the like, is connected to the head 5, and ink is supplied to the head 5 from a plurality of ink cartridges (not shown) mounted in the ink cartridge mounting section 9 via the liquid supply passage (not shown). In the printing apparatus 1 of this embodiment, the transport direction of the medium at a position facing the ink ejection surface 5A is the +Y direction, the movement direction of the head 5, i.e., the scanning direction of the carriage 4, which is the width direction B, is along the X axis direction, and the ink ejection direction is the -Z direction.

[0029] With the above configuration, the head 5 can form an image by ejecting liquid ink from nozzles (not shown) onto the transported medium while reciprocating in the width direction B, which is a direction intersecting the transport direction of the medium. The printing apparatus 1 of this embodiment can form a desired image on the medium by repeatedly transporting the medium at a predetermined transport amount and ejecting ink while moving the head 5 in the width direction B with the medium stopped. However, the configuration is not limited to this, and a so-called line head configuration in which nozzles that eject ink along the width direction B are arranged over the entire width of the medium may also be used.

[0030] As described above, the printing apparatus 1 of this embodiment includes a head 5 for printing on a medium and a housing 100 for housing the head 5. Furthermore, as shown in Figure 1, it includes an opening / closing cover 200 that opens and closes a part of the housing 100, and an operation panel 300 that is provided alongside the opening / closing cover 200 in the width direction B (alignment direction) when the opening / closing cover 200 is closed. The configuration of the opening / closing cover 200 and the configuration of the inside of the opening / closing cover 200 will be described in detail below. Note that "the operation panel 300 that is provided alongside the opening / closing cover 200 in the width direction B (alignment direction) when the opening / closing cover 200 is closed" means that at least a part of the opening / closing cover 200 and at least a part of the operation panel 300 should be provided side by side. As described above, in this embodiment, the alignment direction of the opening / closing cover 200 and the operation panel 300 corresponds to the width direction B (X-axis direction).

[0031] As shown in Figures 1 to 6, the opening / closing cover 200 of the printing apparatus 1 in this embodiment has a first wall 201 which is part of the wall 100A on the first direction side (+Z direction side) of the housing 100, and a second wall 202 which is part of the wall 100B on the second direction side (-X direction side) that intersects with the first wall 201 of the housing 100 and is provided on the opposite side (-X direction side) from the operation panel 300 in the width direction B. The opening / closing cover 200 in this embodiment opens and closes by rotating in the rotation direction R by a pivot shaft 203 provided on the first wall 201 and extending in the width direction B.

[0032] In this embodiment, the opening / closing cover 200 has a contact portion 210 on the inner surface of the second wall 202 of the opening / closing cover 200, as shown in Figures 4 to 6. As shown in Figure 2 and other figures, the housing 100 is provided with a contacted portion 110 that comes into contact with the contact portion 210 when the opening / closing cover 200 is closed. From another perspective, the contacted portion 110 is provided on a part of the housing 100, and when the opening / closing cover 200 is closed, the contact portion 210 comes into contact with the contacted portion 110, pressing the opening / closing cover 200 in the -X direction as a whole, and displacing the opening / closing cover 200 so that it moves away from the operation panel 300. From yet another perspective, the printing apparatus 1 in this embodiment has a contact portion 210 at a location other than the part of the opening / closing cover 200 that may come into contact with the operation panel 300, thereby displacing the opening / closing cover 200 so that it moves away from the operation panel 300. Furthermore, when the opening / closing cover 200 does not twist or otherwise move in a direction that would cause it to contact the operation panel 300, it is preferable that the contact portion 210 and the contacted portion 110 are positioned so that they do not come into contact when the opening / closing cover 200 is opened or closed. Alternatively, the positions where the contact portion 210 and the contacted portion 110 are formed may be reversed, with the contacted portion 110 provided on the opening / closing cover 200 and the contact portion 210 provided on a part of the housing 100.

[0033] In this embodiment, the opening / closing cover 200 of the printing apparatus 1 has a second wall 202 on which the contact portion 210 is provided. This second wall 202 is part of the wall 100B (on the -X direction) and is located on the opposite side (-X direction) from the side where the operation panel 300 is located in the width direction B. However, the second wall 202 on which the contact portion 210 is provided may be configured as part of the wall 100C on the third direction side (+Y direction) of the housing 100. However, it is preferable that the second wall 202 on which the contact portion 210 is provided is located on the opposite side (-X direction) from the side where the operation panel 300 is located in the width direction B. This is because it is particularly effective in displacing the opening / closing cover 200 away from the operation panel 300, and particularly effective in preventing the opening / closing cover 200 from contacting the operation panel 300 when closing the opening / closing cover 200. Furthermore, although the contact portion 110 of the printing apparatus 1 in this embodiment is provided on a part of the housing 100, the configuration is not limited to this, and the contact portion 110 may be provided inside the housing 100 as a component separate from the housing 100.

[0034] Thus, it is preferable that a contact portion 210 is provided on the inner surface of the second wall 202 of the opening / closing cover 200, which displaces the opening / closing cover 200 so as to move it away from the operation panel 300 by contacting a part of the housing 100 or a contacted portion 110 provided inside the housing 100 when the opening / closing cover 200 is closed. This configuration makes it possible to suppress the opening / closing cover 200, which is provided alongside the operation panel 300, from coming into contact with the operation panel 300 when the opening / closing cover 200 is closed.

[0035] As shown in Figures 2 and 3, the printing apparatus 1 of this embodiment exposes a wide opening 400 in the housing 100 by opening the opening / closing cover 200. The wall 100B of the housing 100 on the second direction side (-X direction side) that constitutes the opening 400 extends deeper than the position of the head 5 in the -Z direction, which is the opposite direction to the first direction. Here, the opening / closing cover 200 is configured to completely cover the opening 400, as shown in Figure 1.

[0036] Thus, by having the second-direction wall 100B of the housing 100 have an opening 400 that extends beyond the position of the head 5 in the -Z direction, the opening 400 can be made larger, improving the efficiency of work performed with the opening / closing cover 200 open. Furthermore, if the opening / closing cover 200 is configured to cover a deep opening 400 and the opening / closing cover 200 is configured to be long in the depth direction, the opening / closing cover 200 generally becomes larger and more prone to twisting. However, by providing the opening / closing cover 200 with a contact portion 210 that contacts the contact portion 110 when the opening / closing cover 200 is closed, displacing the opening / closing cover 200 so that it moves away from the operation panel 300, it is possible to suppress the opening / closing cover 200, which is provided alongside the operation panel 300, from contacting the operation panel 300 when the opening / closing cover 200 is closed.

[0037] In this embodiment, the opening / closing cover 200 in the printing apparatus 1 is made of resin. By making the opening / closing cover 200 out of resin, the opening / closing cover 200 can be made lighter, and the efficiency of work performed with the opening / closing cover 200 open can be improved.

[0038] While such resin opening / closing covers 200 are generally prone to twisting, the opening / closing cover 200 is provided with a contact portion 210 that, when the opening / closing cover 200 is closed, contact with the contact portion 110 causes the opening / closing cover 200 to be displaced away from the operation panel 300. This prevents the opening / closing cover 200, which is provided alongside the operation panel 300, from contacting the operation panel 300 when the opening / closing cover 200 is closed. Here, "the opening / closing cover 200 is made of resin" means that the opening / closing cover 200 is made primarily of resin, and may contain some other materials such as metal.

[0039] The inside of the opening / closing cover 200 is the standby position of the print head 5 when it is not printing, the so-called home position of the print head 5. When the print head 5 is in the home position, a cap 404 that covers the nozzles of the ink ejection surface 5A is provided at a position facing the ink ejection surface 5A, as shown in Figure 2. In addition, a flushing box 403 for flushing is provided at a position adjacent to the cap 404 on the -X side, and a suction cap 402 for sucking the nozzles of the ink ejection surface 5A is provided at a position adjacent to the flushing box 403 on the -X side. Furthermore, a degassing unit 405 for removing air bubbles from the ink is provided at a position adjacent to the suction cap 402 on the -X side.

[0040] Furthermore, a cloth wiper 401 capable of wiping the ink ejection surface 5A is provided on the -X side of the degassing unit 405. The cloth wiper 401 is movable along the Y axis, and while moving along the Y axis, it wipes the ink ejection surface 5A with a roll of cloth 401A that is wound in a roll shape. The home position of the cloth wiper 401 is on the -Y side of the movement range of the head 5, and when the opening / closing cover 200 is opened when the head 5 has moved to its maximum extent in the -X direction, the ink ejection surface 5A can be visually inspected from below through the opening 400, making it possible to clean the ink ejection surface 5A with a cotton swab or the like. To facilitate such work, the opening 400 extends to a deep position in the -Z direction. The opening / closing cover 200 is also configured to open the wide opening 400.

[0041] In other words, the inside of the opening / closing cover 200 is both the home position of the head 5 and the maintenance position for performing maintenance on the head 5. From another perspective, the opening / closing cover 200 in this embodiment is a maintenance cover that can be opened and closed when an operator performs maintenance on the head 5. Furthermore, by opening the opening / closing cover 200, the maintenance unit, including the cloth wiper 401, suction cap 402, flushing box 403, cap 404, and degassing unit 405, can be replaced and cleaned.

[0042] From another perspective, the printing apparatus 1 of this embodiment includes a maintenance unit comprising a cloth wiper 401, a suction cap 402, a flushing box 403, a cap 404, and a degassing unit 405, and the opening / closing cover 200 is configured to cover the maintenance unit when closed. In this way, the printing apparatus 1 can be kept in a suitable condition by providing the maintenance unit.

[0043] Furthermore, in the printing apparatus 1 of this embodiment, the opening / closing cover 200 is configured to cover the maintenance unit when closed, and when the opening / closing cover 200 is opened, a large portion of the housing 100 that covers the maintenance unit is opened, making the opening / closing cover 200 larger to facilitate maintenance work. However, even though the opening / closing cover 200 is larger, as described above, a contact portion 210 is provided on the opening / closing cover 200 that, when closed, comes into contact with the contact portion 110, displacing the opening / closing cover 200 so that it moves away from the operation panel 300. This configuration prevents the opening / closing cover 200, which is provided alongside the operation panel 300, from coming into contact with the operation panel 300 when the opening / closing cover 200 is closed.

[0044] As described above, the opening / closing cover 200 of this embodiment has a first wall 201 that constitutes part of wall 100A and a second wall 202 that constitutes part of wall 100B. The second wall 202 has a first portion 202A that is close to wall 100A and a second portion 202B that is farther from wall 100A. In the second wall 202 of the printing apparatus 1 of this embodiment, the thickness L2 of the second portion 202B is thinner than the thickness L1 of the first portion 202A, as shown in Figure 4. The printing apparatus 1 of this embodiment has such a configuration that makes it easy to open and close the opening / closing cover 200. As an embodiment in which "the thickness L2 of the second portion 202B is thinner than the thickness L1 of the first portion 202A", in addition to a configuration in which the first portion 202A and the second portion 202B are stepped, a configuration in which the thickness gradually decreases from the first portion 202A to the second portion 202B may also be used.

[0045] Here, the shape of the contact portion 210 in this embodiment will be described in more detail. The contact portion 210 in this embodiment is a protruding portion that protrudes toward the contacted portion 110 when the opening / closing cover 200 is closed. With this configuration, the contact portion 210 in this embodiment can be easily constructed.

[0046] Furthermore, the contact portion 210 in this embodiment, which is a protruding portion, is a plate-shaped component that extends in the tangential direction of the arc centered on the pivot axis 203 of the opening / closing cover 200. With this configuration, the contact portion 210 in this embodiment can bring the contact portion 210 and the contacted portion 110 into contact with high precision as the opening / closing cover 200 closes. Therefore, the contact portion 210 in this embodiment is configured to particularly effectively prevent the opening / closing cover 200, which is provided alongside the operation panel 300, from contacting the operation panel 300 when the opening / closing cover 200 is closed. The contact portion 210 in this embodiment is provided on the inner surface of the second wall 202 such that, when the opening / closing cover 200 is closed, the surface of the plate-shaped portion extends intersecting the Y and Z directions.

[0047] Furthermore, as shown in Figures 4 and 5, the contact portion 210 of this embodiment, which is a plate-like portion, has a tapered shape 210A at the end tangential to the arc centered on the pivot axis 203 of the opening / closing cover 200. In this embodiment, the contact portion 210 protrudes most towards the contacted portion 110 near its center with respect to the tangential direction of the arc centered on the pivot axis 203, and the tapered shape 210A is arranged on both sides of the most protruding portion. With this configuration, the contact portion 210 of this embodiment can suppress snagging or other issues between the contact portion 210 and the contacted portion 110 when the opening / closing cover 200 comes into contact with it. Therefore, the contact portion 210 of this embodiment is configured to suppress malfunctions in opening and closing the opening / closing cover 200.

[0048] Furthermore, in the printing apparatus 1 of this embodiment, the extension amount of the contacted portion 110 in the -Z direction is adjusted to be short, so that when the opening / closing cover 200 is completely closed, the contact between the contact portion 210 and the contacted portion 110 is released. Therefore, even when opening the opening / closing cover 200 from a completely closed state, the contact portion 210 and the contacted portion 110, which were in a non-contact state, come into contact. Because the printing apparatus 1 of this embodiment has this configuration, the tapered shape 210A at both ends of the contact portion 210 in the extension direction makes it possible to suppress malfunctions in opening and closing the opening / closing cover 200 not only when closing the opening / closing cover 200, but also when opening the opening / closing cover 200 from a completely closed state.

[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]
