Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in a conventional media conveyance device having a plurality of media conveyance paths, there is a risk that foreign matter attached to the media scatters inside the device. This is because, for example, foreign matter attached to the media may adhere to and accumulate on the switching unit, and the foreign matter accumulated on the switching unit may spill inside the device due to displacement of the switching unit or the like. For example, in the inkjet printer of Patent Document 1, there is a risk that foreign matter accumulates on the switching unit opened by the operation of opening the door portion. Then, when the switching unit returns to the conveyance path side by the operation of closing the door portion, there is a risk that the accumulated foreign matter may enter the conveyance path.

Means for Solving the Problems

[0005] To solve the above problems, the media transport device of the present invention comprises a switching unit for switching the transport direction of a medium in a transport path, and a door unit that can be opened and closed relative to an opening, and is displaceable between a closed state that covers the switching unit when closed relative to the opening, and an open state that exposes the switching unit when opened relative to the opening, wherein the switching unit is displaced to a switching position that switches the transport direction of the medium when the door unit is in the closed state, and to an open position that opens the transport path when the door unit is in the open state, and a through hole is formed in the switching unit.

[Modes for carrying out the invention]

[0007] The present invention will be described in general terms below. A media transport device according to the first embodiment includes a switching unit for switching the transport direction of a medium in a transport path, and a door unit that can be opened and closed relative to an opening, and is displaceable between a closed state that covers the switching unit when closed relative to the opening, and an open state that exposes the switching unit when opened relative to the opening, wherein the switching unit is displaced to a switching position for switching the transport direction of the medium when the door unit is in the closed state, and to an open position for opening the transport path when the door unit is in the open state, and a through hole is formed in the switching unit.

[0008] According to this aspect, a through hole is formed in the switching portion. With such a configuration, even if foreign matter drops onto the switching portion in the open position, the foreign matter can pass through the through hole, so that it is possible to suppress the accumulation of foreign matter on the switching portion. Further, even if foreign matter adheres to a position other than the through hole of the switching portion, when the switching portion is displaced from the open position to the switching position as the door portion closes, the foreign matter can be made to pass through the through hole by the air passing through the through hole. Therefore, it is possible to suppress the scattering of the foreign matter adhering to the switching portion within the apparatus.

[0009] The medium conveyance device according to the second aspect is an aspect subordinate to the first aspect, wherein the switching portion has ribs with which the medium makes sliding contact, and the through hole is formed outside the ribs with respect to the center in the width direction intersecting the conveyance direction of the medium.

[0010] According to this aspect, the switching portion has ribs with which the medium makes sliding contact, and the through hole is formed outside the ribs with respect to the center in the width direction. With such a configuration, since the ribs can lift the end portion of the medium being conveyed, it is possible to suppress the end portion of the medium from getting caught in the through hole. Therefore, it is possible to suppress a decrease in the conveyance accuracy of the medium.

[0011] The medium conveyance device according to the third aspect is an aspect subordinate to the first or second aspect, wherein the through hole has a shape in which the longitudinal direction is along the conveyance direction of the medium.

[0012] According to this aspect, the through hole has a shape in which the longitudinal direction is along the conveyance direction of the medium. With such a configuration, it is possible to suppress the end portion of the medium from getting caught in the through hole. Therefore, it is possible to suppress a decrease in the conveyance accuracy of the medium.

[0013] The media conveyance device according to the fourth aspect is an aspect subordinate to any one of the first to third aspects, and includes a first conveyance roller that conveys a media. The switching unit has a first opposing region that opposes above the first conveyance roller at the open position, and a first non-opposing region that does not oppose above the first conveyance roller at the open position. The through hole is formed in the first non-opposing region.

[0014] According to this aspect, the through hole of the switching unit is formed in the first non-opposing region that does not oppose above the first conveyance roller at the open position. By adopting such a configuration, it is possible to effectively suppress the adhesion of foreign matter to the first conveyance roller.

[0015] The media conveyance device according to the fifth aspect is an aspect subordinate to the fourth aspect, and the switching unit has a holding unit that holds foreign matter in the first opposing region. The holding unit is located between the first conveyance roller and the first opposing region when the switching unit is in the switching position.

[0016] According to this aspect, the switching unit has a holding unit that holds foreign matter in the first opposing region, and the holding unit is located between the first conveyance roller and the first opposing region when the switching unit is in the switching position. By adopting such a configuration, when a through hole cannot be provided in the first opposing region, foreign matter can be held by the holding unit.

[0017] The media conveyance device according to the sixth aspect is an aspect subordinate to the fifth aspect, and the holding unit is provided across the entire switching unit in the width direction that intersects the conveyance direction of the media.

[0018] According to this aspect, the holding unit is provided across the entire switching unit in the width direction. By adopting such a configuration, foreign matter can be held across the entire width direction of the switching unit, so that it is possible to effectively suppress the adhesion of foreign matter to the first conveyance roller.

[0019] The media transport device according to the seventh embodiment is an embodiment dependent on the fifth embodiment, characterized in that the holding portion is provided over the entire width of the first transport roller in the width direction intersecting the transport direction of the media.

[0020] According to this embodiment, the holding portion is provided across the entire width of the first conveyor roller in the width direction. With this configuration, the falling of foreign matter across the entire width direction of the first conveyor roller can be suppressed, and thus the adhesion of foreign matter to the first conveyor roller can be effectively prevented.

[0021] The media transport device according to the eighth embodiment is an embodiment dependent on any one of the fifth to seventh embodiments, and is characterized by comprising a protective part for protecting the first transport roller, wherein the holding part and the protective part are located between the first transport roller and the first opposing region when the switching part is in the switching position, and the protective part overlaps the holding part in the direction when the first transport roller is viewed from the first opposing region.

[0022] According to this embodiment, a protective part is provided to protect the first conveyor roller, and the holding part and the protective part are located between the first conveyor roller and the first opposing region when the switching part is in the switching position, and the protective part overlaps with the holding part in the direction when viewing the first conveyor roller from the first opposing region. With this configuration, the protective part and the holding part can effectively suppress the adhesion of foreign matter to the first conveyor roller.

[0023] A media transport device according to the ninth embodiment is an embodiment dependent on the fourth embodiment, characterized in that when the switching unit is in the open position, the surface facing upward of the first opposing region is the upper surface, and the upper surface is flat.

[0024] According to this embodiment, the upper surface of the first opposing region of the switching section is flat. With this configuration, it is possible to suppress the accumulation of foreign matter in the first opposing region, for example, when a through hole cannot be provided in the first opposing region.

[0025] A media transport device according to the tenth embodiment is an embodiment dependent on any one of the first to ninth embodiments, comprising a pair of separation rollers for separating a medium, wherein the switching section has a second opposing region that faces the pair of separation rollers at the switching position and a second non-opposing region that does not face the pair of separation rollers at the switching position, and the through hole is formed in the second opposing region.

[0026] According to this embodiment, the switching section has a second opposing region that faces the separation roller pair at the switching position, and a second non-opposing region that does not face the separation roller pair at the switching position, and the through hole is formed in the second opposing region. The rollers of the separation roller pair are more prone to conveying defects such as double feeding due to a decrease in frictional force caused by the adhesion of foreign matter compared to rollers of other conveying roller pairs, but with this configuration, by providing a through hole in the second opposing region that faces the separation roller pair at the switching position, foreign matter located in the second opposing region can be released through the through hole. In other words, the accumulation of foreign matter in the second opposing region can be suppressed, and the adhesion of foreign matter to the separation roller pair when the switching section returns from the open position to the switching position can be suppressed. Therefore, a decrease in conveying accuracy can be suppressed.

[0027] The recording device according to the 11th embodiment is characterized by comprising a media transport device according to the 10th embodiment and a recording unit that performs recording on a medium transported by the media transport device.

[0028] According to this embodiment, recording can be performed while suppressing the scattering of foreign matter adhering to the switching part within the device.

[0029] A recording device according to the 12th embodiment is an embodiment dependent on the 11th embodiment, comprising a support portion facing the recording portion and supporting a medium to be recorded by the recording portion, wherein the support portion is displaceable between a facing position and a separated position, and the support portion is located above the switching portion.

[0030] According to this embodiment, the device is equipped with a support portion that faces the recording portion and supports the medium to be recorded by the recording portion, and the support portion is displaceable between a facing position and a separated position, and is located above the switching portion. In a configuration in which the support portion is located above the switching portion and is displaceable, there is a risk that foreign objects may fall onto the switching portion from above due to the displacement of the support portion. However, even in such a configuration, it is possible to suppress the movement of foreign objects to positions other than the desired position as described above, thereby suppressing the effects of foreign objects.

[0031] A recording device according to the 13th embodiment is an embodiment dependent on the 12th embodiment, characterized in that the support unit includes a conveyor belt for conveying a medium, a cleaning unit for cleaning the conveyor belt, and a storage unit for storing foreign matter removed by the cleaning unit.

[0032] According to this embodiment, the support unit includes a conveyor belt for transporting a medium, a cleaning unit for cleaning the conveyor belt, and a storage unit for storing foreign matter removed by the cleaning unit. In a configuration where the support unit has a storage unit, foreign matter may fall from the storage unit due to displacement of the support unit. However, even in such a configuration, it is possible to suppress the movement of foreign matter to a position other than the desired position as described above, thereby suppressing the effects of foreign matter.

[0033] A recording device according to the 14th embodiment is characterized by comprising a media transport device according to any one of the first to 9 embodiments, and a recording unit that performs recording on a medium transported by the media transport device.

[0034] According to this embodiment, recording can be performed while suppressing the scattering of foreign matter adhering to the switching part within the device.

[0035] A recording device according to the 15th embodiment comprises a media transport device according to any one of the 4th to 9th embodiments, a recording unit that performs recording on a medium transported by the media transport device, and a second transport roller that transports a medium that has not been recorded on by the recording unit, wherein the first transport roller transports a medium that has been recorded on by the recording unit, the switching unit has a third opposing region that faces the second transport roller in the open position, and a third non-opposing region that does not face the second transport roller in the open position, and the through hole is formed in the third opposing region.

[0036] According to this embodiment, recording can be performed while suppressing the scattering of foreign matter adhering to the switching part within the device.

[0037] [Example 1] The present invention will now be described in detail. First, an inkjet printer 1 of Embodiment 1, which is both a media transport device and a recording device of the present invention, will be described. Hereinafter, the printer 1 of this embodiment, which is the inkjet printer 1, will be abbreviated as printer 1A. In each figure, the XYZ coordinate system is a Cartesian coordinate system, and the Y axis direction is the direction that intersects the transport direction of the medium P, i.e., the medium width direction, and also the device depth direction. Of the Y axis directions, the +Y direction is the direction from the front of the device to the back of the device, and the -Y direction is the direction from the back of the device to the front of the device.

[0038] The X-axis direction is the width direction of the device, with +X being the left direction and -X being the right direction from the perspective of the printer 1A operator. The Z-axis direction is the vertical direction, i.e., the height direction of the device, with +Z being the upward direction and -Z being the downward direction. In the following, the direction in which the medium P is fed will be referred to as "downstream," and the opposite direction as "upstream." In each figure, the transport path of the medium is shown by a dashed line. In printer 1A, the medium P is transported through the transport path shown by the dashed line.

[0039] The printer 1A comprises a housing 16 of the main body 2 and a door 17 that can rotate relative to the housing 16 with the Z-axis as the pivot axis. Opening the door 17 opens an opening 18 provided in the housing 16, and closing the door 17 closes the opening 18. The printer 1A also has a first media cassette 3 for storing media P at the bottom of the main body 2, and is configured to allow connection of an expansion unit 6 to the lower side of the main body 2. When the expansion unit 6 is connected, the second media cassette 4 and the third media cassette 5 are located below the first media cassette 3. The media P sent out from each media cassette is transported within the printer 1A along the transport path shown by the dashed line.

[0040] Each media cassette is provided with a pick roller that feeds the contained media P in the -X direction. Pick rollers 21, 22, and 23 are provided for the first media cassette 3, the second media cassette 4, and the third media cassette 5, respectively. Each media cassette is also provided with a pair of feed rollers that feed the media P fed in the -X direction diagonally upward. Feed roller pairs 25, 26, and 27 are provided for the first media cassette 3, the second media cassette 4, and the third media cassette 5, respectively. In the following, unless otherwise specified, a "roller pair" consists of a drive roller driven by a motor (not shown) and a driven roller that rotates in contact with the drive roller.

[0041] The media P dispensed from the third media cassette 5 is sent to the reversing roller 39 by the transport roller pairs 29 and 28. Similarly, the media P dispensed from the second media cassette 4 is sent to the reversing roller 39 by the transport roller pair 28. The media P is nipped by the reversing roller 39 and the driven roller 40 and sent to the transport roller pair 31. The media P dispensed from the first media cassette 3 is sent to the transport roller pair 31 without passing through the reversing roller 39. The supply roller 19 and separation roller 20 located near the reversing roller 39 are the roller pair that dispenses the media P from the supply tray 12.

[0042] The transport path of the medium P between the feed roller pair 25 and the transport roller pair 31 is curved so as to be convex downwards. Also, the transport path of the medium P from the nip position between the reversing roller 39 and the driven roller 40 to the transport roller pair 31 is also curved so as to be convex downwards. Hereinafter, the transport path of the medium P between the feed roller pair 25 and the transport roller pair 31, and the transport path of the medium P from the nip position between the reversing roller 39 and the driven roller 40 to the transport roller pair 31 will be referred to as the curved transport path R1.

[0043] The curved transport path R1 is provided with a detection means 70 for detecting the medium P and a switching unit 100 for switching the transport path of the medium P. In this embodiment, the switching unit 100 is referred to as the switching unit 100A. The detection means 70 detects the presence or absence of the medium P being transported along the curved transport path R1 and detects the width of the medium P by detecting the edges of the medium P in the medium width direction. Further details of the switching unit 100A, which is a key part of the printer 1A in this embodiment, will be described later.

[0044] The medium P, which receives the feeding force from the transport roller pair 31, is transported between the line head 51, which is an example of a recording unit, and the transport belt 13, that is, to the recording position facing the line head 51. In the following, the transport path from the transport roller pair 31 to the transport roller pair 32 will be referred to as the recording transport path T1.

[0045] The line head 51 constitutes the head unit 50. The line head 51 performs recording by ejecting ink, which is an example of a liquid, onto the surface of the medium P. The line head 51 is an ink ejection head configured such that the nozzles that eject the ink cover the entire area in the width direction of the medium, and is configured as an ink ejection head that can record over the entire width of the medium without moving in the width direction of the medium. However, the ink ejection head is not limited to this, and may also be a type that is mounted on a carriage and ejects ink while moving in the width direction of the medium. Furthermore, it is also possible to use a recording unit other than an ink ejection head, such as a thermal transfer recording unit.

[0046] The head unit 50 is provided to be able to move forward and backward relative to the transport path T1 during recording, and is provided to be able to move between the recording position shown by the solid line in Figure 1 and the retracted position, which is the furthest away from the transport belt 13, as shown by the dashed line and reference numeral 50-1 in Figure 1. When the head unit 50 is in the retracted position, maintenance of the line head 51 is performed by maintenance means not shown. The head unit 50 is located on the upstream side in the media discharge direction below the discharge tray 8 and is able to move along the lower surface 8e of the discharge tray 8.

[0047] Printer 1A is equipped with ink storage units 61, 62, 63, and 64, which serve as liquid storage units. Ink ejected from the line head 51 is supplied to the line head 51 from each ink storage unit via tubes (not shown). Each ink storage unit is detachable. Printer 1A also includes a waste liquid storage unit 11 for storing waste ink ejected from the line head 51 toward a flushing cap (not shown) for maintenance purposes.

[0048] The conveyor belt 13 is an endless belt that is wrapped around pulleys 14 and 15, and rotates when at least one of the pulleys 14 and 15 is driven by a motor (not shown). The medium P is transported to a position facing the line head 51 while being attracted to the belt surface of the conveyor belt 13. A known attraction method such as an air suction method or an electrostatic attraction method can be used to attract the medium P to the conveyor belt 13. As will be described in detail later, in addition to the conveyor belt 13, pulleys 14 and 15, a blade 53 which is a cleaning unit for cleaning the conveyor belt 13, and a storage unit 54 which contains foreign matter T such as paper dust removed by the blade 53 constitute a belt unit 52 that serves as a support for the medium P recorded by the line head 51.

[0049] The recording transport path T1, which passes opposite the line head 51, is configured to transport the medium P upwards, forming an angle with respect to the horizontal and vertical directions. This upward transport direction includes the -X and +Z components in Figure 1. The medium P, on which the first surface has been recorded by the line head 51, is further transported upwards by the transport roller pair 32 located downstream of the transport belt 13. A flap 41 is provided downstream of the transport roller pair 32, and this flap 41 switches the transport direction of the medium P. When the medium P is to be discharged as is, the transport path of the medium P is switched by the flap 41 to head towards the upper transport roller pair 35, and the medium P is discharged towards the discharge tray 8 by the transport roller pair 35.

[0050] When recording is to be performed on a second surface opposite to the first surface of the medium P, the transport direction of the medium P is directed towards the branching position K1 by the flap 41. The medium P then passes through the branching position K1 and enters the switchback path T2. In this embodiment, the switchback path T2 is the transport path above the branching position K1. The switchback path T2 is provided with a pair of transport rollers 36 and 37. Once the medium P enters the switchback path T2, it is transported approximately upward by the pair of transport rollers 36 and 37. When the rear end edge of the medium P passes the branching position K1, the rotation direction of the pair of transport rollers 36 and 37 is switched, and the medium P is transported approximately downward.

[0051] A reversal path T3 is connected to the switchback path T2. In this embodiment, the reversal path T3 is the transport path from the branching point K1, passing through the transport roller pair 33, 34 and the reversal roller 39 to the merging point P1. The medium P transported downward from the branching point K1 receives a feeding force from the transport roller pair 33, 34, reaches the reversal roller 39, is curved and reversed by the reversal roller 39, and is sent towards the transport roller pair 31.

[0052] The medium P, transported by the transport roller pair 31 and other means, is sent to a position facing the line head 51 again, so that the second side, opposite to the first side on which recording has already been done, faces the line head 51. This makes it possible for the line head 51 to record on the second side of the medium P. Here, the transport path from the first medium cassette 3 to the switching unit 100A is referred to as the supply path T0. Therefore, the switching unit 100A is located at the confluence point P1 of the supply path T0 and the reversal path T3, and the transport path from the downstream side of the confluence point P1 of the supply path T0 and the reversal path T3 to the transport roller pair 32 constitutes the recording transport path T1. The transport path of the medium P sent out from the supply tray 12 by the supply roller 19 and the separation roller 20 is referred to as the supply path T4.

[0053] As described above, the printer 1A is equipped with a door portion 17 that can be opened and closed relative to the opening 18, and is displaceable between a closed state, which covers the switching portion 100A when closed relative to the opening 18, and an open state, which exposes the switching portion 100A when opened relative to the opening 18. The switching portion 100A is configured to switch the transport direction of the medium P in the transport path. Next, the switching portion 100A, which is the main part of the printer 1A, will be described in detail with reference to Figures 2 to 9.

[0054] The switching unit 100A is responsible for switching between the supply path T0 and the inversion path T3. Specifically, when supplying media P from the first media cassette 3, the supply path T0 is opened and the inversion path T3 is closed, as shown in Figure 2. On the other hand, when recording is made on the first side of media P and then on the second side of media P, or when the expansion unit 6 is connected to the main unit 2 and media P is supplied from the second media cassette 4 or third media cassette 5, the inversion path T3 is opened and the supply path T0 is closed, as shown in Figure 3. Similarly, when supplying media P from the supply tray 12, the inversion path T3 is opened and the supply path T0 is closed, as shown in Figure 3.

[0055] As shown in Figures 2 and 3, the switching section 100A has a switching section pivot shaft 101 that extends in the Y-axis direction. The switching section 100A can rotate with respect to the switching section pivot shaft 101. In Figures 2 and 3, the tip 102 of the switching section 100A opposite to the switching section pivot shaft 101 is located on the +X side of the switching section pivot shaft 101. Therefore, due to its own weight, the switching section 100A basically assumes the second state shown in Figure 3. However, when media P is fed from the first media cassette 3, the tip of the media P in the feeding direction comes into contact with the switching section 100A and pushes the contact area 105 of the switching section 100A toward the -X side, causing the switching section 100A to return to the first state shown in Figure 2.

[0056] Here, the printer 1A can be in a closed state where the door portion 17 is closed to the opening 18 of the housing portion 16, as shown in Figures 2 and 3, or in an open state where the door portion 17 is open to the opening 18. When the printer 1A is in the open state where the door portion 17 is open to the opening 18, the switching unit 100A enters a third state as shown in Figures 6 and 9. When the switching unit 100A changes from the second state to the third state by opening the door portion 17, it rotates to open the feed path T0 as seen from the opening 18. That is, as shown in Figures 2 and 3, the switching unit 100A can be displaced to a switching position that switches the transport direction of the medium P when the door portion 17 is in the closed position. Furthermore, as shown in Figures 6 and 9, it can be displaced to an open position that opens the transport path when the door portion 17 is in the open position.

[0057] When the door 17 is opened, the belt unit 52 shown in Figure 4 is also exposed from the opening 18. As will be described later, when the door 17 is opened, the belt unit 52 can also be opened through the opening 18. As shown in the enlarged view of region S1 in Figure 4 and in Figure 5, the storage section 54 that constitutes the belt unit 52 has an opening 54a on the side facing the conveyor belt 13. The belt unit 52 is configured to scrape off foreign matter T such as paper dust attached to the conveyor belt 13 with the blade 53 and to store the foreign matter T in the storage section 54 through the opening 54a.

[0058] However, because the storage section 54 has an opening 54a, when the belt unit 52 is exposed to view through the opening 18, the user may touch the components of the belt unit 52, such as the conveyor belt 13, causing foreign matter T stored in the storage section 54 to spill out through the opening 54a. In that case, as shown in Figure 6, the foreign matter T spilled from the storage section 54 may fall in the direction of arrow E0 and accumulate in the switching section 100A, which is in the third state.

[0059] Furthermore, the printer 1A is a media transport device capable of collecting foreign matter T, such as paper dust, adhering to the media P using a belt unit 52 within the device. As described above, it is equipped with a storage section 54 for collecting foreign matter T when the transport belt 13 is cleaned by the blade 53. The belt unit 52 in this embodiment is configured to rotate in direction D1 in Figure 4 with the pulley 14 as the pivot axis. With this configuration, if a jam occurs, the media in which the jam has occurred can be easily removed. However, with this configuration, when the belt unit 52 is rotated in direction D1 and then returned to its original position, foreign matter T contained in the storage section 54 may spill out from the opening 54a.

[0060] Furthermore, as shown in Figure 6, if foreign matter T accumulates in the switching section 100A when it is in the third state, and the door section 17 is closed while the switching section 100A is returned to the second state, there is a risk that the foreign matter T will adhere to the feed roller pair 25. For example, Figure 16 shows how, in the reference example printer 1D, foreign matter T accumulated in the switching section 100D moves in the direction of arrow E6 and adheres to the feed roller pair 25. Therefore, the printer 1A of this embodiment is configured to make it difficult for foreign matter T to accumulate in the switching section 100A when it is in the third state. Specifically, as shown in Figure 7, multiple through holes H are formed in the switching section 100A. Note that the switching section 100D of the reference example printer 1D does not have through holes H formed in it.

[0061] In this embodiment, the printer 1A has the following configuration: even if a foreign object T falls into the switching section 100A in the open position, the foreign object T can pass through the through-hole H, as shown by arrow E1 in Figure 8. Therefore, the accumulation of foreign object T in the switching section 100A can be suppressed. Furthermore, even if a foreign object T adheres to a position other than the through-hole H in the switching section 100A, as the door section 17 closes and the switching section 100A moves in the rotational direction D2, displacing it from the open position to the switching position, the airflow E3 passing through the through-hole H can allow the foreign object T to pass through the through-hole H. Therefore, the movement of foreign object T to a position other than the desired position where its presence does not substantially cause problems can be suppressed.

[0062] Therefore, printer 1A can suppress the scattering of foreign matter T attached to the switching section 100A within the device. There are no particular limitations on the shape or size of the through hole H. However, it is desirable that the shape and size do not impair the strength of the switching section 100A. In Figures 8 and 16, both the switching section 100 in the open position and the switching section 100 in the switched position are shown, but this only illustrates how the switching section 100 moves in the rotation direction D2 and is displaced from the open position to the switched position, and in both cases, printer 1 has only one switching section 100.

[0063] From the perspective of the recording device, the printer 1A includes a media transport device having a through hole H formed in the switching unit 100A, and a line head 51 that records on the media P transported by the media transport device. Therefore, the printer 1A can perform recording while suppressing the scattering of foreign matter T adhering to the switching unit 100A within the device.

[0064] As shown in Figures 2 and 3, the printer 1A has a switching section 100A with contact areas 104 and 105, which are areas that come into contact with the medium P being transported together. Contact area 104 is the area that comes into contact with the medium P being transported from the reversal path T3 and the feed path T4 to the recording transport path T1, and contact area 105 is the area that comes into contact with the medium P being transported from the feed path T0 to the recording transport path T1. As shown in Figures 7 and 10, the contact area 104 is provided with ribs C that extend in the direction along the transport direction.

[0065] In other words, the switching section 100A has a rib C with which the conveyed medium P slides. The through hole H is formed outside the center of the rib C in the width direction (Y-axis direction) intersecting the conveying direction of the medium P, as shown in the enlarged view of region S2 in Figure 7 and in Figure 10. With this configuration, the printer 1A can lift the end Pe of the conveyed medium P with the rib C, thereby preventing the end Pe of the medium P from getting caught in the through hole H. In particular, depending on the width of the medium, the end Pe of the medium P may be located near the through hole H. In such cases, the rib C can lift the end Pe of the conveyed medium P, so it is possible to more effectively prevent the end Pe of the medium P from getting caught in the through hole H. Therefore, the printer 1A can suppress a decrease in the conveying accuracy of the medium.

[0066] In printer 1A, the switching section 100A is formed of resin by injection molding, but in order to suppress deformation associated with injection molding, the wall thickness is made to be as constant as possible. Therefore, as shown in Figure 7, the switching section 100A is provided with a recess 104a that is recessed when viewed from the contact area 104 side, and the recess 104a is given the role of material removal. When a recess 104a is provided in this way, foreign matter T tends to accumulate in the recess 104a, so taking measures as in this embodiment is more effective.

[0067] Furthermore, in printer 1A, as shown in Figure 7, the through-hole H has a shape whose longitudinal direction is aligned with the transport direction of the medium P. This configuration effectively prevents the end portion Pe of the medium P from getting caught in the through-hole H. Therefore, printer 1A can effectively suppress a decrease in the transport accuracy of the medium P.

[0068] In the example printer 1D, if foreign matter T accumulates in the switching section 100D, since there is no through hole, it is conceivable that the foreign matter T may adhere to the feed roller pair 25 and the driven roller 40 due to its positional relationship with the switching section 100D. Also, in printer 1A, if a through hole H is provided in the entire area of ​​the switching section 100A, it is conceivable that the foreign matter T may adhere to the transport roller pair 28 and the driven roller 40 due to its positional relationship with the switching section 100A. As shown in Figures 2, 3, and 8, the feed roller pair 25 has some areas facing each other in the X-axis direction when the switching section 100A is in the switching position corresponding to the first and second states. Foreign matter T may adhere to the feed roller pair 25 when the switching section 100A is displaced from the open position corresponding to the third state to the switching position, for example.

[0069] As shown in Figures 6 and 8, the driven roller 40 has a portion of its area facing the other in the Z-axis direction when the switching section 100A is in the open position. Foreign matter T may adhere to the driven roller 40 when the foreign matter T falls downward when the switching section 100A is in the open position. Similarly, as shown in Figure 9, the transport roller pair 28 also has a portion of its area facing the other in the Z-axis direction when the switching section 100A is in the open position. Foreign matter T may adhere to the transport roller pair 28 when the foreign matter T falls downward when the switching section 100A is in the open position.

[0070] Here, the feeding roller pair 25 is a separation roller pair capable of separating the double-feeded media P. Since the separation roller pair requires a strong frictional force to separate the double-feeded media P, a decrease in frictional force due to the adhesion of foreign matter T is undesirable. For example, the separation roller pair is configured to separate the single-feeded media P by a feeding roller that applies a conveying force in the conveying direction F to the single-feeded media P, and a separation roller that applies a force that inhibits the movement in the conveying direction to the media P other than the single-feeded media P. At this time, if foreign matter T adheres to the separation roller, the force inhibiting movement in the conveying direction weakens, which may lead to conveying defects such as double-feeding. Therefore, it is preferable to avoid the adhesion of foreign matter T to the separation roller pair as much as possible.

[0071] Furthermore, the driven roller 40, together with the reversing roller 39, nips and transports the medium P. The driven roller 40 and the reversing roller 39 are located in the reversal path T3 when recording is performed on the first side and then on the second side. When transporting the medium P with recording on the first side, it is desirable that the nipping force by the driven roller 40 and the reversing roller 39 not be too strong in order to suppress distortion of the recorded image formed on the first side. For this reason, a decrease in the transport force of the driven roller 40 must be suppressed, and it is preferable to avoid the adhesion of foreign matter T to the driven roller 40 as much as possible.

[0072] On the other hand, the conveyor roller pair 28 may tolerate the adhesion of foreign matter T compared to the feed roller pair 25 and the driven roller 40. Therefore, the conveyor roller pair 28 does not need to be subjected to the same strict measures against the adhesion of foreign matter T as the feed roller pair 25 and the driven roller 40.

[0073] The above will be further explained using different terminology, corresponding to printer 1A. First, the driven roller 40 as the first transport roller will be explained. As described above, printer 1A is equipped with a driven roller 40 as the first transport roller for transporting the medium P. Here, as shown in Figures 6, 8, and 9, the switching section 100A has a first opposing region M1 that faces the driven roller 40 above it in the open position, and a first non-opposing region N1 that does not face the driven roller 40 above it in the open position. The through hole H is formed in the first non-opposing region N1.

[0074] With this configuration, even if foreign matter T accumulates in the first opposing region M1 of the switching section 100A in the open position, it is possible to suppress the foreign matter T from falling onto the driven roller 40 through the through hole H, thereby effectively suppressing the adhesion of foreign matter T to the driven roller 40. However, if there is any component between the first opposing region M1 and the driven roller 40, even if the position of the first opposing region M1 is above the position of the driven roller 40, these can be considered not to be opposing each other. Furthermore, if the adhesion of foreign matter T to the driven roller 40 is not considered a particular problem, such as when some measures have been taken to prevent performance degradation due to the adhesion of foreign matter T to the driven roller 40, a through hole H may also be provided in the first opposing region M1.

[0075] Here, at least a portion of the upper surface 106 of the switching unit 100A, which faces upward in the open position of the first opposing region M1, may be a flat surface. With this configuration, foreign matter T can move more easily on the upper surface 106, and by moving the foreign matter T out of the first opposing region M1, it is possible to suppress the accumulation of foreign matter T in the first opposing region M1, such as when a through hole H cannot be provided in the first opposing region M1. The upper surface 106 may be a horizontal plane or not when the switching unit 100A is in the open position corresponding to the third state, but if the upper surface 106 is not a horizontal plane, it becomes easier to move the foreign matter T in a desired direction.

[0076] Next, the feed roller pair 25, which serves as a separation roller pair, will be described. As described above, the printer 1A is equipped with a feed roller pair 25, which serves as a separation roller pair for separating the medium P. Here, as shown in Figures 2, 3, and 8, the switching unit 100A has a second opposing region M2 that faces the feed roller pair 25 in the X-axis direction at the switching position, and a second non-opposing region N2 that does not face the feed roller pair 25 at the switching position. The through hole H is formed in the second opposing region M2.

[0077] The rollers of the separation roller pair are more susceptible to transport defects such as double feeding due to reduced frictional force caused by the adhesion of foreign matter T compared to rollers of other transport roller pairs. However, printer 1A has such a configuration, and by providing a through hole H in the second opposing region M2 that faces the feed roller pair 25, which is the separation roller pair, at the switching position, foreign matter T located in the second opposing region M2 can escape through the through hole H. For example, as shown in Figure 8, the airflow E3 passing through the through hole H allows foreign matter T located in the second opposing region M2 to pass through the through hole H, as shown by arrow E2, and foreign matter T located in the second opposing region M2 can pass through the through hole H. Therefore, printer 1A can suppress the accumulation of foreign matter T in the second opposing region M2, and can suppress the adhesion of foreign matter T to the feed roller pair 25 when the switching unit 100A returns from the open position to the switching position. Consequently, printer 1A can suppress a decrease in transport accuracy.

[0078] Finally, the transport roller pair 28, which serves as the second transport roller, will be described. As shown in Figure 9, the switching section 100A has a third opposing region M3 that faces the transport roller pair 28 in the open position, and a third non-opposing region N3 that does not face the transport roller pair 28 in the open position. The through hole H is formed in the third opposing region M3. In printer 1A, the third opposing region M3 corresponds to the first non-opposing region N1, and the third non-opposing region N3 corresponds to the first opposing region M1, but the configuration is not limited to such a correspondence.

[0079] The printer 1A, with this configuration, can perform recording while suppressing the scattering of foreign matter T adhering to the switching unit 100A within the device. To explain from another perspective, the transport roller pair that transports the medium P that has not yet been recorded on is less likely to suffer from problems such as transfer even if the nip pressure is increased, but increasing the nip pressure of the transport roller pair that transports the medium P that has been recorded on at least one side may cause transfer. Therefore, the transport roller pair 28, which acts as the second transport roller, is less likely to suffer problems even if the nip pressure is increased in advance or adjusted to be higher afterward as a countermeasure against the decrease in transport force due to the adhesion of foreign matter T such as paper dust, but it is difficult to increase the nip pressure of the driven roller 40, which acts as the first transport roller, in the same way as the second transport roller. In other words, the transport roller pair 28 is less likely to experience a decrease in transport force even if some foreign matter T such as paper dust adheres to it. Therefore, as in this embodiment, by not providing a through hole H at a position facing the first conveyor roller, but providing a through hole H at a position facing the second conveyor roller, it is possible to more effectively suppress the occurrence of conveying defects caused by foreign matter T.

[0080] Furthermore, as described above, the printer 1A is equipped with a belt unit 52 that faces the line head 51 and serves as a support for the medium P recorded by the line head 51. As described above, the belt unit 52 is rotatable in direction D1 in Figure 4 with the pulley 14 as the pivot axis. In other words, the belt unit 52 is displaceable between a position facing the belt unit 52 and a position separated from the belt unit 52. Here, as shown in Figure 1, the belt unit 52 is located above the switching unit 100A.

[0081] As described above, in a configuration like printer 1A, where the belt unit 52 is located above the switching section 100A and is displaceable, there is a risk that foreign matter T may fall into the switching section 100A from above due to the displacement of the belt unit 52. However, even in such a configuration where the belt unit 52 is displaceable, by providing a through hole H at an appropriate position in the switching section 100A, as in printer 1A, it is possible to suppress the movement of foreign matter T to a position other than the desired position, as described above. Therefore, printer 1A can suppress the effects of foreign matter T.

[0082] As described above, the belt unit 52 of the printer 1A includes a transport belt 13 for transporting the medium P, a blade 53 for cleaning the transport belt 13, and a storage section 54 for storing foreign matter T removed by the blade 53. In the case where the belt unit 52 has a storage section 54, foreign matter T may fall out of the storage section 54 due to the displacement of the belt unit 52. However, even with such a configuration, the printer 1A can suppress the movement of foreign matter T to a position other than the desired position, as described above, and thus can suppress the effects of foreign matter T. In this embodiment, the storage section 54 has an opening 54a on the transport belt 13 side, but the printer is not limited to this configuration.

[0083] [Example 2] Next, the printer 1B, which serves as a media transport device and recording device in Example 2, will be described using Figures 11 to 13. In Figures 11 to 13, components common to Example 1 are indicated by the same reference numerals, and detailed explanations will be omitted. Here, the printer 1B of this example has the same configuration as the printer 1A of Example 1, except for the configuration of the switching unit 100 (switching unit 100B) which will be described below. Therefore, with respect to parts other than those described below, the printer 1B of this example has the same characteristics as the printer 1A of Example 1.

[0084] As shown in Figures 11 to 13, the printer 1B of this embodiment is provided with a rib 111 in the first opposing region M1 on the contact area 105 side of the switching section 100B. As shown in Figure 12, the rib 111 can hold foreign matter T when the switching section 100B is in the open position corresponding to the third state. From another point of view, the switching section 100B has a rib 111 as a holding part that holds foreign matter T in the first opposing region M1. The rib 111 is located between the driven roller 40, which is the first transport roller, and the first opposing region M1 when the switching section 100B is in the switching position as shown in Figure 13.

[0085] In this embodiment, the printer 1B has the following configuration: when a through hole H cannot be provided in the first opposing region M1, the rib 111, which acts as a holding part, can hold the foreign object T. Furthermore, when the switching part 100B returns to the switching position as shown in Figure 13, the foreign object T moves in the direction of arrow E4, but the rib 111 and the driven roller 40 can be configured to overlap, in other words, the back side of the region of the rib 111 that holds the foreign object T can face the driven roller 40. Therefore, it is possible to suppress the foreign object T held by the rib 111 from adhering to the driven roller 40.

[0086] In this embodiment, printer 1B has a through hole H in the first non-facing region N1, as shown in Figure 11. However, the effect of suppressing the adhesion of foreign matter T held by the holding part to the first transport roller occurs even without a through hole H, as long as there is a holding part in the first facing region M1 that holds the foreign matter T, and the holding part is positioned between the first transport roller and the first facing region M1 when the switching part is in the switching position. Furthermore, by suppressing the adhesion of foreign matter T held by the holding part to the first transport roller, the scattering of foreign matter attached to the switching part within the device can be suppressed. In addition, the holding part may be configured to hold the foreign matter T so that it does not fall almost completely, or it may be configured to hold the foreign matter T so that it does not fall to places where it is not desired, and allows it to fall to places where it is acceptable.

[0087] In printer 1B, the rib 111, which serves as a holding part, is provided near the center of the switching part 100B in the Y-axis direction corresponding to the width direction intersecting the transport direction of the medium P, as shown in Figure 11. In this embodiment, the driven roller 40 is provided near the center in the width direction of the medium P. That is, the rib 111, which serves as a holding part, is provided across the entire width of the driven roller 40 in the width direction of the medium P. With this configuration, printer 1B can suppress the falling of foreign matter T across the entire width direction of the driven roller 40, and thus effectively suppress the adhesion of foreign matter T to the driven roller 40. In the case where the first transport roller is divided into multiple parts, the holding part may be provided corresponding to each roller, with each holding part covering each individual roller, or all rollers may be covered by a single holding part.

[0088] Alternatively, the holding portion may be provided across the entire switching portion 100 in the width direction of the medium P. With this configuration, foreign matter T can be held across the entire width direction of the switching portion 100, thereby effectively suppressing the adhesion of foreign matter T to the first conveyor roller.

[0089] Furthermore, as shown in Figures 12 and 13, the printer 1B is provided with a wall portion 112 on the +X direction side of the driven roller 40. In other words, the printer 1B is equipped with a wall portion 112 as a protective part that protects the driven roller 40. Here, as shown in Figure 13, when the switching unit 100B is in the switching position, the rib 111 and the wall portion 112 are located between the driven roller 40 and the first opposing region M1, and the tip of the wall portion 112 overlaps with the tip of the rib 111 in the direction when viewing the driven roller 40 from the first opposing region M1 (downward right direction in Figure 13). With this configuration, the printer 1B can effectively suppress the adhesion of foreign matter T to the driven roller 40 by the wall portion 112 and the rib 111.

[0090] [Example 3] Next, the printer 1C, which serves as a media transport device and recording device in Example 3, will be described using Figures 14 and 15. In Figures 14 and 15, components common to Examples 1 and 2 are indicated by the same reference numerals, and detailed explanations will be omitted. Here, the printer 1C of this embodiment has the same configuration as the printer 1 of Examples 1 and 2, except for the configuration of the switching unit 100 (switching unit 100C) which will be described below. Therefore, with respect to parts other than those described below, the printer 1C of this embodiment has the same characteristics as the printer 1 of Examples 1 and 2.

[0091] As described above, in the printer 1B of Embodiment 2, the retaining part provided on the switching part 100B was a rib 111. On the other hand, in the printer 1C of this embodiment, as shown in Figures 14 and 15, the switching part 100C is provided with a retaining part 113 whose upper surface 113a, which faces upward in the open position of the first opposing region M1, is flat. In other words, when the switching part 100C is in the open position, the upward-facing surface (upper surface 113a) of the first opposing region M1 is flat. With this configuration, the printer 1C can be configured to allow foreign matter T on the upper surface 113a to fall to a location where it is acceptable to fall, as shown by arrow E5 in Figure 15, and it is possible to suppress the accumulation of foreign matter T in the first opposing region M1, such as when a through hole H cannot be provided in the first opposing region M1.

[0092] Furthermore, the upper surface 113a does not have to be a horizontal plane when the switching section 100C is in the open position corresponding to the third state, and may be formed retrofitting to fill the rib C, or it may be molded as a flat surface from the beginning. If the upper surface 113a is not a horizontal plane, as in the printer 1C of this embodiment, tilting the upper surface 113a in a desired direction makes it easier to move the foreign object T in a desired direction, such as away from the driven roller 40.

[0093] The present invention is not limited to the embodiments described above, and it goes without saying that various modifications are possible within the scope of the invention as described in the claims, and these modifications are also included within the scope of the present invention. For example, the media transport device is not limited to printers. For example, it may be applied to media transport devices in scanners, intermediate units provided between various devices, or finishers. [Explanation of Symbols]
