Description

Technical Field

[0001] This invention relates to a pipeline device, an airflow generating device, and a recording device. Background Technology

[0002] Various pipe systems have been used that use fans to circulate gas within pipes. Among these, there are pipe systems where the fan is fixed to the pipe using screws or other fixing components. For example, Patent Document 1 discloses an image forming apparatus that includes a pipe, and a fan is fixed to the pipe using screws.

[0003] In pipe fittings where a fan is fixed to a pipe using screws or other fasteners, the fan sometimes needs to be cleaned or replaced. Therefore, the fan is configured to be detachable relative to the pipe. For example, Patent Document 1 discloses that when installing a fan at the pipe opening, a screw is inserted parallel to the fan's mounting direction and secured with the screw. In other words, the fan's mounting direction and the screw's fixing direction are the same. However, in existing pipe fittings like the image forming apparatus of Patent Document 1, where a fan is fixed to a pipe using screws or other fasteners, it is difficult to install or remove the fan relative to the pipe if there is no space for removing the screws in the fan's mounting direction. That is, making the fan easy to install or remove leads to the larger size of the fitting.

[0019] The present invention will now be described in summary.

[0020] The first aspect of the pipe device of the present invention is characterized in that it is equipped with a fan section having a fan, and gas is circulated by the fan. The pipe device includes: a first mounting section for assembling the fan section in an opposing configuration along a first direction; and a fixing section for fixing the fan section by a fixing member, the fixing member fixing the fan section and the fixing section along a second direction intersecting the first direction.

[0021] According to this method, the device includes: a first assembly part for assembling a fan part in a configuration facing each other along a first direction; and a fixing part for fixing the fan part to a fixing member, the fixing member fixing the fan part and the fixing part along a second direction intersecting the first direction. That is, the mounting direction of the fan part and the fixing direction of the fan part are intersecting. Therefore, even when there is no space in the first direction, the fan can be approached from the second direction and the fan can be installed and removed relative to the duct. Thus, the installation and removal of the fan can be facilitated while simultaneously reducing the size of the suppression device.

[0022] The second aspect of the present invention relates to a piping device in which, in a manner subordinate to the first aspect, the fixing part is located downstream of the center of the fan in the insertion direction of the fixing member along the second direction.

[0023] According to this method, the fixing part is located downstream of the center of the fan in the insertion direction of the fixing component. By setting the structure in this way, space more than half the length of the fan section can be ensured for accessing the fan.

[0024] The pipe device according to the third aspect of the present invention is characterized in that, in the aspect subordinate to the second aspect, the fixing part is located downstream of the fan in the insertion direction.

[0025] According to this method, the fixing part is located downstream of the fan in the insertion direction of the fixing component. By setting the structure in this way, space above the length of the fan can be ensured for accessing the fan.

[0026] The fourth aspect of the present invention relates to a piping device in which, in any of the first to third aspects, the fixing part is located within the range where the fan is configured in the first direction.

[0027] According to this method, in the first direction, the fixing part is located within the area where the fan is configured. By configuring it in this way, the space of the device in the first direction can be reduced, and thus the size of the device in the direction intersecting the first direction can be reduced.

[0028] The fifth aspect of the present invention relates to a piping device in which, in any of the first to fourth aspects, the fan portion has the fan and a mounting portion mounted on the fixed portion, the mounting portion having a fixed portion fixed on the fixed portion, the fixed portion and the fixed portion extending along the first direction.

[0029] According to this method, the fan section has a fan and a mounting section mounted on the fixed section. The mounting section has a fixed part that is fixed to the fixed section, and the fixed section and the fixed part extend along a first direction. By configuring it in this way, the fixed part can be inserted into and fixed to the fixed part in a second direction.

[0030] The sixth aspect of the present invention relates to a pipe device in which, in a manner subordinate to the fifth aspect, the fixed part is formed of metal, and the fixing member is screwed onto the fixed part.

[0031] According to this method, the fixed part is formed of metal, and the fixing component is screwed onto the fixed part. By adopting such a structure, the fixed part can be firmly constructed using metal, and thus the fixed part can be reused. Therefore, when replacing the fan, only the fan needs to be replaced by reusing the fixed part, thereby reducing environmental impact.

[0032] The pipe device according to the seventh aspect of the present invention is characterized in that, in a manner subordinate to the fifth or sixth aspect, the fixing part has a limiting part that restricts the movement of the fixed part in the first direction.

[0033] According to this method, the fixing part has a limiting part that restricts the movement of the fixed part in the first direction. By configuring it in this way, it is possible to suppress the wobbling of the fan part and thus improve the positional accuracy in the first direction.

[0034] The piping device according to the eighth aspect of the present invention is characterized in that, in any of the first to seventh aspects, the fan part has the fan and a mounting part mounted on the fixed part, and the first assembly part has a restraining part that restricts the movement of the mounting part in the first direction.

[0035] According to this method, the fan unit has a fan and a mounting part mounted on the fixed part, and the first assembly part has a restraining part that restricts the movement of the mounting part in a first direction. Although the positional accuracy in the first direction may decrease if the direction of fixing by the fixed part is not the first direction, by setting it in this way, the wobbling of the fan unit can be suppressed by the restraining part, thereby improving the positional accuracy in the first direction.

[0036] The pipe device according to the ninth aspect of the present invention is characterized in that, in the aspect belonging to the eighth aspect, the mounting part has a restricted part that is restricted to move in the first direction by the restricting part, and the restricted part can switch between a state of being engaged with the restricting part and a state of not being engaged by causing the fan part to slide in a direction intersecting the first direction.

[0037] According to this method, the mounting section has a restricted section that is restricted to move in a first direction by a restricting section. The restricted section can switch between a state of engagement with the restricting section and a state of disengagement by causing the fan section to slide along a direction intersecting the first direction. With such a structure, engagement between the restricting section and the restricted section can be easily achieved.

[0038] The pipeline device according to the tenth aspect of the present invention is characterized in that, in any of the first to ninth aspects, it includes a second assembly part, which is capable of assembling a collection part for capturing foreign objects, the collection part being assembled on the second assembly part along the second direction.

[0039] According to this method, a second assembly section is provided, which is capable of assembling a collection section for capturing foreign objects. The collection section is assembled onto the second assembly section along a second direction. With this structure, foreign objects can be captured in the pipeline. Furthermore, since the changing direction of the collection section and the approach direction towards the fixed component can both be set to the same direction along the second direction, maintenance of the device can be easily performed from one direction, and the space required for maintenance can be reduced.

[0040] The airflow generating device according to the eleventh aspect of the present invention is characterized in that it includes a duct device of any one of the first to tenth aspects and the fan unit.

[0041] According to this method, an airflow generating device can be made that makes it easy to install and remove the fan while simultaneously increasing the size of the suppression device.

[0042] The airflow generating device according to the twelfth aspect of the present invention is characterized in that, in a manner subordinate to the eleventh aspect, it includes a frame on which the pipe device is mounted, the pipe device being mounted on the frame along the second direction.

[0043] According to this method, a frame is provided on which a pipe assembly is installed, and the pipe assembly is installed on the frame along a second direction. By configuring it in this way, the installation direction of the pipe assembly and the approach direction of the fixed component are both aligned with the second direction, thus making it easy to maintain the assembly from one direction and reducing the space required for maintenance.

[0044] The airflow generating device according to the thirteenth aspect of the present invention is characterized in that, in a manner subordinate to the eleventh or twelfth aspect, it includes a housing that houses the pipe device, and the housing has an upstream opening in the insertion direction of the fixing member along the second direction.

[0045] According to this method, a housing is provided to house the piping device, and the housing has an upstream opening in the insertion direction of the fixing member along the second direction. By configuring it in this way, the opening provided on the housing is made to be on the upstream side in the insertion direction of the fixing member, thereby making it easy to install or remove the fixing member or the fan from the opening.

[0046] The recording apparatus according to the fourteenth aspect of the present invention is characterized by comprising: a recording unit that records a medium; and an airflow generating device according to any one of the eleventh to thirteenth aspects.

[0047] According to this method, a recording device can be configured to facilitate the installation and removal of the fan while simultaneously increasing the size of the suppression device.

[0048] The recording device according to the fifteenth aspect of the present invention is characterized in that, in a manner subordinate to the fourteenth aspect, it includes a control unit that controls the recording unit, wherein the distance between the control unit in the first direction and the airflow generating device is less than the distance between the end of the pipe device and the fixing part in the insertion direction of the fixing member along the second direction.

[0049] According to this method, a control unit is provided to control the recording unit, and the distance between the control unit in the first direction and the airflow generating device is less than the distance between the end of the pipe device and the fixing unit in the insertion direction of the fixing member in the second direction. By providing such a structure, even if the control unit obstructs access to the fixing member from the first direction, the fixing member can still be accessed from the second direction, thus making maintenance easy.

[0050] The present invention will now be described in detail. First, referring to... Figure 1 as well as Figure 2Hereinafter, a summary description of a recording apparatus according to an embodiment of the present invention will be provided. As an example of the recording apparatus of this embodiment, an inkjet printer 10 (hereinafter, sometimes simply referred to as printer 10) will be used. Furthermore, in the XYZ coordinate system shown in the figures, the X-axis direction represents the width direction of the medium P in the transport path within the recording apparatus, the Y-axis direction represents the length direction of the medium P recorded by the recording unit described later, and the Z-axis direction represents the height direction of the apparatus. Additionally, the Y-axis direction is the width direction of the apparatus.

[0051] The printer 10 is configured as a multifunction printer comprising a main body 12 and a scanning unit 14. The main body 12 includes multiple media storage boxes 16 for storing media P. Each media storage box 16 is installed in a manner that allows it to be loaded and unloaded from the front surface side of the main body 12, i.e., the -X-axis direction side. Furthermore, in this specification, the term "media P" as an example refers to paper such as plain paper, thick paper, or photographic paper.

[0052] Furthermore, in the device height direction within the device body 12, between the scanning unit 14 and the media receiving box 16, recording is performed in the recording unit 18. After recording, the media P is discharged from the outlet 23a of the discharge unit 23. Additionally, a media holding unit 20 is provided to receive the media P discharged from the outlet 23a. The media holding unit 20 has a rib 19 extending in the transport direction at the center of its mounting surface in the width direction (X-axis direction) intersecting the transport direction (-Y direction) of the media P discharged from the discharge unit 23.

[0053] In this embodiment, the printer 10 has a media transport path 21 inside the housing 13. The media transport path 21 includes a straight path 22, a downward discharge path 28, and a feed path 30 connecting the media receiving box 16 to the straight path 22. Furthermore, the media transport path 21 includes a turning path 24 and a flipping path 26, thereby being configured to perform so-called double-sided recording, which involves recording on a second side of the media P after recording on a first side.

[0054] Along the feeding path 30, a feeding roller 32, a separating roller pair 33, and a conveying roller pair 34 are arranged sequentially along the conveying direction of the medium P. The feeding roller 32 is driven to rotate by a drive source (not shown). The separating roller pair 33 separates the medium P by clamping it between the driving roller 33a and the driven roller 33b.

[0055] The conveyor roller pair 34 consists of a drive roller and a driven roller. Each drive roller is controlled by a control unit 90 located within the main body 12 and via a drive source (not shown). Furthermore, the line head 48, described later, is also controlled by the control unit 90. In other words, the control unit 90 is configured to perform the controls required for the recording operations in the printer 10.

[0056] In the following description, it is assumed that one of the conveying roller pairs appearing in this specification is configured as a driven roller, and the other roller is configured as a drive roller that is rotated and driven by a drive source (not shown). Furthermore, in this embodiment, unless otherwise specified, one roller is configured as a spur gear having multiple teeth on its outer circumference, and the other roller, i.e., the drive roller, is configured as a rubber roller as an example.

[0057] The medium P stored in the medium storage box 16 is supported on the hopper 17 provided inside the medium storage box 16. The hopper 17 rotates about the rotation shaft 17a provided on the hopper 17, thereby lifting the medium P upward. At this time, the feed roller 32 contacts the uppermost medium P supported on the hopper 17 and conveys the medium P downstream in the conveying direction. At this time, although sometimes the next medium P is also conveyed together with the uppermost medium P, the uppermost medium P is separated from the next medium P by the separation roller pair 33, so that only the uppermost medium P is conveyed downstream in the conveying direction.

[0058] A conveyor roller pair 36 is provided downstream of the conveyor roller pair 34 in the conveying direction. In this embodiment, the feed path 30 is connected to the straight path 22 at the position of the conveyor roller pair 36. That is, the feed path 30 is set as a path from the medium receiving box 16 to the conveyor roller pair 36.

[0059] The straight path 22 is configured as a straight path extending in a straight line, and along the conveying direction, a pair of conveyor rollers 36, a conveying mechanism 40 consisting of a drive roller 38, a driven roller 42, and a seamless belt 41, a recording unit 18, and a first baffle 46 are arranged sequentially. In this embodiment, the straight path 22 is set as a path from the pair of conveyor rollers 36 to the first baffle 46. The seamless belt 41 is energized by a voltage application unit (not shown). The seamless belt 41 uses the electrostatic charge obtained from this energization to attract the medium P, and the attracted medium P is conveyed in the conveying direction Y while facing the recording unit 18. At this time, by using the electrostatic brush 103 to remove the charge on the printing surface of the medium P, the reduction in the electrostatic attraction force of the medium P caused by the seamless belt 41 is suppressed.

[0060] The recording unit 18 includes a line head 48. A transport mechanism 40 is provided below the line head 48. In this embodiment, the line head 48 is configured to spray ink onto the recording surface of the medium P to perform recording when the medium P is transported to a position opposite the line head 48 on the transport mechanism 40. The line head 48 is a recording head configured such that the nozzles that spray ink cover the entire width of the medium P, and is configured as a recording head that can record the entire width of the medium without accompanying movement in the width direction of the medium. Although the printer 10 of this embodiment includes a line head 48, it may also include a serial recording head, which is mounted on a carriage and sprays liquid onto the medium to perform recording while reciprocating in a direction intersecting the medium transport direction.

[0061] Furthermore, on the media transport path 21 downstream of the recording unit 18 and the travel head 48, a suction port 102 of a pipe 101, which is part of a fume recovery unit 110, is provided on the side facing the recording surface of the media P. A fan unit 100 is provided on the back side (the surface in the +X direction) of the device body 12, and a fume recovery unit 110 is provided to recover ink fumes generated when ink is ejected from the travel head 48. In addition, a fan unit 100 is provided parallel to the fume recovery unit 110 in the Y-axis direction, and a paper dust recovery unit 120 is provided to recover foreign matter such as paper dust adhering to the brush 103 from the media P. Figure 2 The smoke recovery unit 110 and the paper dust recovery unit 120 are schematically illustrated based on the position of the fan unit 100. Here, both the smoke recovery unit 110 and the paper dust recovery unit 120 are airflow generating devices that are equipped with the fan unit 100a (described later) and use the fan 100a to cause gas to flow within the duct 101 (described later). Furthermore, the portions of the smoke recovery unit 110 and the paper dust recovery unit 120 equipped with the fan unit 100 can be considered as ductwork devices with the duct 101. That is, the fan unit 100 and the portion of the fan unit 100 equipped as a ductwork device can be considered as the smoke recovery unit 110 and the paper dust recovery unit 120 as airflow generating devices.

[0062] A conveying mechanism 40, consisting of a drive roller 38, a driven roller 42, and a seamless belt 41, is provided at a position opposite to the conveying head 48. A first baffle 46 is located downstream in its conveying direction. The first baffle 46 is configured to be switchable by a drive mechanism (not shown) to connect the straight path 22 with the deflection path 24 or to connect the straight path 22 with the downward-facing discharge path 28.

[0063] A second baffle 50 is provided above the first baffle 46 in the height direction (Z-axis direction) of the device. The second baffle 50 is driven by a linkage mechanism (not shown) in a manner that links its movement with that of the first baffle 46. The first baffle 46 and the second baffle 50 are subject to attitude changes under the control of the control unit 90.

[0064] The downward discharge path 28 extends upward from the straight path 22 in the height direction of the device while bending and flipping. Furthermore, the downward discharge path 28 includes a pair of conveying rollers 52, 54, 56, 58, and 60, and a pair of conveying rollers 62 constituting the discharge section 23. The downward discharge path 28 is configured from the first baffle 46 to the outlet 23a located downstream of the conveying roller pair 62 in the conveying direction. In other words, the downward discharge path 28 is a media conveying path 21 connected to the straight path 22, and is a path that flips the recording surface of the medium P that has passed through the recording section 18 between the recording section 18 and the discharge section 23 and conveys it to the discharge section 23.

[0065] The medium P, which has been recorded on the recording surface in the recording unit 18, is conveyed along the downward discharge path 28 by a series of conveying roller pairs 52, 54, 56, 58, 60, and 62, starting from the first baffle 46 and proceeding in the conveying direction. Then, the medium P is discharged from the outlet 23a toward the medium loading unit 20.

[0066] The flipping path 26 is the path for flipping the medium P, and includes a pair of transport rollers 70, a pair of transport rollers 72, and a pair of transport rollers 74. The medium P, which has previously passed through the media transport path 21 (i.e., the straight path 22) opposite the recording unit 18, flips its surface opposite the recording unit 18 by passing through the flipping path 26, and thus passes through the media transport path 21 (i.e., the straight path 22) opposite the recording unit 18 again. By passing through the flipping path 26, recording can be performed on both sides of the medium P.

[0067] Here, also refer to Figure 3 The smoke recovery unit 110, which constitutes the airflow generating device and the ductwork, will be described below. Although... Figure 3 As indicated, a fan unit 100A and ducts 101 (ducts 101A and ducts 101B) are provided in the smoke recovery unit 110, but further, as shown in the figure... Figure 2As shown in the diagram, a plurality of suction ports 102 are provided at a portion of the conduit 101 extending in the X-axis direction along the conduit 101B. Specifically, the suction ports 102 are provided in such a manner that they correspond to the entire area of ​​the ink ejection region in the X-axis direction where ink is ejected by the printhead 48. That is, the suction ports 102 are provided in a manner that spans the width of the medium.

[0068] A duct 101 is provided in the smoke recovery unit 110, and a filter 105 is provided in the duct 101 to purify the air, including the smoke recovered from the suction port 102. Furthermore, the duct 101B of the smoke recovery unit 110 extends from the mounting portion of the fan unit 100 to the downstream side of the conveying direction of the medium P compared to the swivel head 48, and the suction port 102 is provided at the downstream side of the conveying direction of the medium P compared to the swivel head 48. Although the filter 105 in this embodiment absorbs the smoke in the recovered air conveyed from the suction port 102, it can also be further configured to be combined with, for example, a filter containing activated carbon to adsorb volatile organic compounds contained in ink.

[0069] Next, also refer to Figure 3 The paper dust recovery unit 120, which constitutes the airflow generating device and the piping device, will be described below. Figure 2 As shown in the diagram, the paper dust recovery unit 120 is equipped with a dust removal brush 103 and a scraping component (not shown). The dust removal brush 103 is mounted on a seamless strip-shaped substrate that can rotate about the direction along the conveying direction, and extends in the X-axis direction by being mounted on two pulleys (not shown). When the dust removal brush 103 comes into contact with the medium P being conveyed by the seamless belt 41, foreign matter such as paper dust and ink adhering to the medium P will adhere to the dust removal brush 103.

[0070] The scraping component contacts the electrostatic precipitator 103, scraping off or adsorbing the paper dust adhering to the electrostatic precipitator 103, thereby removing the paper dust from the electrostatic precipitator 103. For example... Figure 3 As shown in the diagram, a fan unit 100B and pipes 101 (pipes 101A and 101C) are provided in the paper dust collection unit 120. Foreign matter such as paper dust scraped off by the scraping component is discharged through the pipes 101 (pipes 101A and 101C) constituting the paper dust collection unit 120. Figure 3The dust collection unit 120 is suctioned through a pipe opening (not shown) on the pipe 101C. Additionally, the pipe 101C extends from the pipe 101A where the fan unit 100 is installed to the vicinity of the electrostatic precipitator 103, and a pipe opening is provided near the electrostatic precipitator 103 and the scraping member. A pipe 101 is provided in the dust recovery unit 120, and a filter 105 is provided in the pipe 101 to purify air containing foreign matter such as dust recovered through the pipe opening (not shown). In this embodiment, the filter 105 captures foreign matter in the recovered air delivered through the pipe opening (not shown).

[0071] Here, in the smoke recovery section 110 constituting the airflow generating device and the ductwork device, and the paper dust recovery section 120 constituting the airflow generating device and the ductwork device, the fan section 100 and the mounting portion of the fan section 100 adopt the same structure. Therefore, in the following text, referring to Figures 3 to 12 The detailed structure of the smoke recovery unit 110 constituting the airflow generating device and the ductwork device, the fan unit 100 constituting the paper dust recovery unit 120, and the mounting portion of the fan unit 100 will be explained. Furthermore, although... Figures 4 to 11 The description refers to the fan section 100A and its mounting portion of the smoke recovery unit 110. However, since the fan section 100B and its mounting portion of the paper dust recovery unit 120 also adopt the same structure, the smoke recovery unit 110 will be referred to as the paper dust recovery unit 120 in the following description, so that it can be regarded as a description of the fan section 100 and its mounting portion of the paper dust recovery unit 120.

[0072] As described above, the smoke recovery unit 110 of this embodiment is equipped with a fan unit 100 having a fan 100a, thereby forming a duct device for gas flow via the fan 100a. Figure 4 as well as Figure 6 As indicated, the smoke recovery unit 110 includes an upper surface portion 1011 of a duct 101A, which is a first mounting part for assembling a fan unit 100 in a configuration facing each other along a vertical direction that is a first direction (Z-axis direction), and a fixing portion 107 for fixing the fan unit 100 by means of a metal screw 106 as a fixing member. Here, the metal screw 106 fixes the fan unit 100 and the fixing portion 107 along a second direction (X-axis direction) that intersects the first direction. Furthermore, in this embodiment, the duct 101A is composed of a first plastic portion 101A-1 provided on the +X direction side and a second plastic portion 101A-2 on which the first portion 101A-1 is mounted. The fan unit 100 is mounted on the surface of the second portion 101A-2 on the +Z direction side. In addition, at least a portion of the duct 101A may also be made of metal.

[0073] In this manner, the assembly direction (Z-axis direction) of the fan section 100 and the fixing direction (X-axis direction) of the fan section 100 intersect in relation to the smoke recovery unit 110 of this embodiment. Therefore, even when there is no space in the first direction (Z-axis direction), the smoke recovery unit 110 of this embodiment can approach the fan 100a from the second direction (X-axis direction) and detach the fan 100a together with the fan section 100 from the pipe 101. Therefore, the smoke recovery unit 110 of this embodiment can facilitate the assembly and disassembly of the fan 100a while reducing the size of the suppression device. Furthermore, by adopting such a structure, for example, it is not necessary to use plate-shaped nuts, etc., which has the advantage of reducing the number of parts. Furthermore, by adopting such a structure, it is not necessary to have a structure for installing nuts, etc. on the pipe 101, which has the advantage of simplifying the structure of the pipe 101. In addition, although in this embodiment the assembly direction (Z-axis direction) of the fan section 100 and the fixing direction (X-axis direction) of the fan section 100 are orthogonal, it is not limited to this.

[0074] Preferably, the fixing part 107 is positioned downstream of the center of the fan 100a in the insertion direction (-X direction) of the metal screw 106 along the second direction (X-axis direction). This is because, by arranging it in this way, space of more than half the length of the fan part 100 can be ensured for approaching the fan 100a (fan part 100).

[0075] Furthermore, in the smoke recovery unit 110 of this embodiment, such as Figure 6 As indicated, not only is such a structure satisfied, but the fixing part 107 is positioned downstream of the fan 100a in the insertion direction (-X direction) of the metal screw 106. By configuring the smoke recovery part 110 of this embodiment in such a structure, as a space for approaching the fan 100a, a space exceeding half the length of the fan part 100 is ensured for the length of the fan 100a.

[0076] In addition, such as Figure 4 As indicated, in this embodiment, the smoke recovery unit 110 is structured such that, in the first direction (Z-axis direction), the fixing part 107 is located within the range L3 where the fan 100a is positioned. Figure 4As shown, in the first direction (Z-axis direction), the area L4 where the fixing part 107 is positioned overlaps with the area L3 where the fan 100a is positioned. By configuring it in this way, the space of the device in the first direction (Z-axis direction) can be reduced, thereby reducing the size of the device in the direction intersecting the first direction. In addition, although the area where the fixing part 107 is positioned may not overlap with the area where the fan 100a is positioned in the second direction (X-axis direction), making them overlap allows for further miniaturization of the device.

[0077] Furthermore, in the smoke recovery unit 110 of this embodiment, such as Figure 7 as well as Figure 10 As indicated, the fan section 100 includes a fan 100a and a metal plate 100b, which is mounted on the fixing section 107 as a mounting part. Figure 7 As shown, the fan 100a and the metal plate 100b are fixed by metal screws 100c. A protrusion 1005 for positioning the fan 100a is provided on the metal plate 100b. Furthermore, the metal plate 100b has a fixed portion 1003 that is fixed to the fixing portion 107. Both the fixing portion 107 and the fixed portion 1003 are formed by planes parallel to the first direction (Z-axis direction). By configuring the fixing portion 107 and the fixed portion 1003 to extend along the first direction (Z-axis direction), the fixing portion 107 can be inserted into and fixed to the fixed portion 1003 in the second direction (X-axis direction). In this embodiment, the mounting portion is a metal plate, but it may not be a metal plate.

[0078] To further explain from another perspective, the fixed part 1003 has a screw hole 1004 and is formed of metal. The metal screw 106 is screwed into the fixed part 1003 while the fixed part 107, which has a hole 1071 through which the screw can pass, is clamped between the head of the metal screw 106 and the fixed part 1003. With this structure, the fixed part 1003 can be robustly constructed using metal, and thus can be reused. Therefore, when replacing the fan part 100, only the fixed part 1003 needs to be reused, and only the fan 100a needs to be replaced, thus reducing environmental impact. Furthermore, although the hole 1071 in this embodiment is a round hole, it can also be a U-shaped hole opening in the +Z direction. By using a U-shaped hole, the fixed part 107 and the fixed part 1003 can be attached and detached even without completely disassembling and loosening the metal screw 106.

[0079] Furthermore, if the screw or the fixed part 1003, which serves as the fixing part, is made of plastic and screwed on, the plastic part cannot be reused. This is because the screwed-on plastic part is prone to deformation. On the other hand, by adopting the structure of this embodiment, the positional relationship between the fixed part 1003 and the head of the metal screw 106 clamping the fixing part 107 is substantially defined, so that the fan part 100 is properly positioned. In addition, although in this embodiment, by making the entire mounting part a metal plate, it can also be reused when the fan 100a is mounted on the metal plate, but it is not limited to such a structure, and a material other than metal can also be used for a part of the mounting part.

[0080] Here, in the smoke recovery unit 110 of this embodiment, as Figure 11 As indicated, the fixing part 107 is provided with an eave 1072 that faces the fixed part 1003 from the +Z direction side when the fan part 100 is assembled in the appropriate position. Alternatively, the fixing part 107 has the eave 1072 as a limiting part that restricts the movement of the fixed part 1003 in the first direction (Z-axis direction). By providing such a structure, the smoke recovery unit 110 of this embodiment can suppress wobbling of the fan part 100 and improve positional accuracy in the first direction (Z-axis direction).

[0081] Furthermore, in the smoke recovery unit 110 of this embodiment, as... Figure 7 As indicated, a protrusion 1001 protruding in the +X direction is provided on the metal plate 100b. Furthermore, as... Figure 8 as well as Figure 9 As indicated, on the second portion 101A-2 of the duct 101A where the fan section 100 is mounted, an eave 1002 is provided that faces the protrusion 1001 from the +Z direction side when the fan section 100 is mounted in the appropriate position. In other words, the upper surface portion 1011 of the duct 101A, which is the first mounting part, has an eave 1002 that serves as a restraining part for restricting the movement of the metal plate 100b in the first direction (Z-axis direction).

[0082] The smoke recovery unit 110 of this embodiment, by having such a structure, can suppress the swaying of the fan unit 100 by means of the eaves 1002, thereby improving the positional accuracy in the first direction (Z-axis direction). Furthermore, particularly in the case of the smoke recovery unit 110 of this embodiment, where the fixing part 107 is located at the end (-X direction side end), although there is a possibility of swaying at the part away from the fixing part 107 (+X direction side end), even with such a structure, swaying can be appropriately suppressed. Moreover, by having such a structure, a plate-shaped nut is not required, thereby reducing the number of parts. Furthermore, although in this embodiment, since the eaves 1002, as a restraining part, restricts the movement of the protrusion 1001 provided at the +X direction side end of the metal plate 100b, thus more effectively suppressing swaying, it is not limited to this. That is, a structure in which the restraining part restricts the part other than the +X direction side end of the mounting part can also be used.

[0083] Here, the replacement procedure for the fan unit 100 will be explained. Figure 4 This indicates that the fan unit 100 is installed on the duct 101A. Furthermore, while the fan unit 100A of the smoke recovery unit 110 is not required when replacing it, the fan unit 100B of the paper dust recovery unit 120 must be disassembled beforehand. Figure 2 The shielding metal plate 131 is shown. Since the shielding metal plate 131 is a component that is fixed by screws in the X-axis direction, it can be easily removed by unscrewing the screws.

[0084] First, from Figure 4 The metal screw 106 is then removed from the indicated state. Next, by moving the fan unit 100 in the -X direction along the duct 101A, the fixed part 1003 is disengaged from the eaves 1072, and the protrusion 1001 of the metal plate 100b is disengaged from the eaves 1002, allowing the fan unit 100 to move in the +Z direction. Thereafter, the fan unit 100 is moved from the duct 101A in the +Z direction. Figure 5 This indicates that the fan unit 100 has been moved from the pipe 101A in the +Z direction. Then, the fan unit 100 is moved in the +X direction to remove the fan unit 100 from the device.

[0085] When installing the new fan unit 100, set the new fan unit 100 as... Figure 5The fan 100 is positioned in the -Z direction and placed on the pipe 101A. At this time, the fixed part 1003 is located on the -X direction side compared to the fixed part 107. Then, a fine adjustment is made so that the screw hole 1004 of the fixed part 1003 aligns with the hole 1071 of the fixed part 107 when viewed from the X-axis direction, and the metal screw 106 is tightened. As the metal screw 106 is tightened, the fan part 100 slides on the pipe 101A in the +X direction. With this sliding, the eaves 1072 is positioned opposite the fixed part 1003 from the +Z direction side, and the eaves 1002 is positioned opposite the protrusion 1001 of the metal plate 100b from the +Z direction side. Alternatively, the metal screw 106 can be tightened after the fan part 100 has slid on the pipe 101A in the +X direction. Furthermore, although it is not necessary when replacing the fan unit 100A of the smoke recovery unit 110, it will be installed afterward when replacing the fan unit 100B of the paper dust recovery unit 120. Figure 2 The shielding metal plate 131 is referred to.

[0086] In this manner, the metal plate 100b, which serves as the mounting part, has a protrusion 1001 that serves as the restrained part. The protrusion 1001 is restrained in its movement in a first direction (Z-axis direction) by the eaves 1002, which serves as the restraining part. Furthermore, by causing the fan part 100 to slide along a direction intersecting the first direction (X-axis direction), the protrusion 1001 can switch between a state of engagement with the eaves 1002 and a state of disengagement. This structure allows for easy engagement between the restraining part and the restrained part. Although this embodiment describes a structure that slides in the X-axis direction while being fixed with a screw, it could also be a structure that slides in the Y-axis direction while being fixed with a screw, or a structure where the movement of the fan part 100 in the +Z direction is restrained by the restraining part through sliding in the Y-axis direction, or a structure where movement is restricted by a limiting part.

[0087] Furthermore, in the smoke recovery unit 110 of this embodiment, such as Figures 3 to 6 As indicated, the side portion 1012 of the pipe 101A, which is a second mounting part, is equipped with a filter 105, which serves as a collection unit for capturing foreign matter such as paper dust or smoke. Here, the filter 105 is a structure that is mounted on the side portion 1012 of the pipe 101A along a second direction (X-axis direction).

[0088] By configuring the structure in this way, foreign objects can be captured in the pipe 101. Furthermore, since the replacement direction of the filter 105 and the approach direction towards the metal screw 106 are both set to the same direction along the second direction (X-axis), maintenance of the device can be easily performed from one direction, and the space required for maintenance can be reduced. The replacement direction of the filter 105 can also be set to the direction along the Y-axis, etc.

[0089] Here, from the viewpoint of an airflow generating device, the smoke recovery unit 110 of this embodiment includes the aforementioned ductwork and the aforementioned fan unit 100. Therefore, the smoke recovery unit 110 of this embodiment can be configured as an airflow generating device that facilitates the installation and removal of the fan 100a while suppressing the enlargement of the device.

[0090] In addition, such as Figures 3 to 5 As indicated, the printer 10 of this embodiment includes a frame 132. If the frame 132 is considered as a structural component of the airflow generating device, then the smoke recovery unit 110 of this embodiment, which is an airflow generating device, can be considered as having a frame 132 on which a duct device is mounted. Furthermore, the duct device is mounted relative to the frame 132 along the second direction (X-axis direction). By setting it in this way, the mounting direction of the duct device and the approach direction of the metal screw 106 can both be set to the same direction along the second direction (X-axis direction), thus making it easier to maintain the device from one direction and reducing the space required for maintenance.

[0091] Here, as described above, in the smoke recovery unit 110, the upper surface portion 1011 of the fan unit 100 and the duct 101A is fixed by metal screws 106. On the other hand, the duct 101A passes through... Figure 10 The metal screws 108, as indicated, are used to fix the pipe 101A to the frame 132. Further, the pipe 101A is connected via... Figure 10 The metal screws 109 shown are used to fix the pipes 101B and 101C.

[0092] In addition, such as Figure 3 As indicated, the printer 10 of this embodiment includes a housing 13 for housing the tubing device. Here, the housing 13 has an upstream opening along the insertion direction (-X direction) of the metal screw 106 in the second direction (X-axis direction). That is, the interior of the housing 13 can be opened and closed via a door (not shown) in the +X direction. Figure 3The diagram shows the state of the door (not shown) being open. If the housing 13 is considered as a structural component of the airflow generating device, then the smoke recovery unit 110 of this embodiment, which is an airflow generating device, is configured such that the opening provided on the housing 13 is upstream of the insertion direction (-X direction) of the metal screw 106, thereby allowing the metal screw 106 and the fan 100a to be easily installed and removed from the opening.

[0093] From the perspective of a recording device, the printer 10 of this embodiment includes a recording unit 18 (line head 48) for recording media P, and the aforementioned airflow generating devices (smoke recovery unit 110 and paper dust recovery unit 120). Therefore, the printer 10 of this embodiment can be configured as a recording device that allows for easy installation and removal of the fan 100a while reducing the size of the suppression device.

[0094] Furthermore, the printer 10 of this embodiment includes a control unit 90 that controls various structural components of the printer 10, such as the line head 48. Here, as... Figure 12 as well as Figure 13 As indicated, the control unit 90 in this embodiment is a control board. Figure 12 as well as Figure 13 As indicated, the control unit 90 includes a head drive board for controlling the line head 48. Furthermore, the printer 10 of this embodiment is configured such that... Figure 12 as well as Figure 13 The distance L1 between the control unit 90 in the first direction (Z-axis direction) and the smoke recovery unit 110 and paper dust recovery unit 120, which are airflow generating devices, is less than that along the direction indicated by the control unit 90 in the first direction (Z-axis direction). Figure 6 as well as Figure 13 The distance L2 between the ends of the smoke recovery section 110 and the dust recovery section 120, which serve as a conduit device, and the fixing section 107 in the insertion direction (-X direction) of the metal screw 106 in the second direction (X-axis direction). By providing such a structure, the printer 10 of this embodiment allows access to the metal screw 106 from the second direction (X-axis direction) even if the control section 90 obstructs access from the first direction (Z-axis direction), thus facilitating maintenance.

[0095] The present invention is not limited to the embodiments described above, but can be modified in various ways within the scope of the invention as described in the claims, and obviously these modifications are also included within the scope of the present invention.
