[0014] Hereinafter, an embodiment of a medium loading device for loading a medium discharged from a processing device will be described with reference to the drawings.

[0015] Processing device

[0016] First, the processing device is described. The processing device is, for example, an inkjet printer that prints images such as text and photos by ejecting ink, which is an example of a liquid, onto a medium such as paper or cloth. The processing device is not limited to printing, and may also be a device that performs other processing on a medium.

[0017] like Figure 1 As shown, the processing device 11 includes a housing 12. The housing 12 has an opening 13 for discharging the medium 99. In one example, the opening 13 is opened on the front surface of the housing 12. The processing device 11 discharges the medium 99 to the outside of the housing 12 through the opening 13. The processing device 11 discharges the medium 99 forward. The processing device 11 discharges the medium 99 in the first direction D1. The processing device 11 discharges the medium 99 to the medium loading device 21 described later.

[0018] The processing device 11 includes an unwinding unit 14. The unwinding unit 14 is configured to unwind the medium 99 from the roll body R1. The roll body R1 is formed by winding the long medium 99. The unwinding unit 14 rotates the roll body R1 to unwind the medium 99 from the roll body R1. The unwinding unit 14 unwinds the medium 99 unwound from the roll body R1.

[0019] The unwinding section 14 has an unwinding shaft 15. The unwinding shaft 15 is a shaft that supports the roll body R1. The unwinding shaft 15 rotatably supports the roll body R1. The unwinding shaft 15 can support the roll body R1 by contacting the inner periphery of the roll body R1 or by contacting the outer periphery of the roll body R1. The unwinding shaft 15 is mounted on the housing 12. The unwinding shaft 15 can rotate together with the roll body R1. The unwinding section 14 can rotate the roll body R1 by rotating the unwinding shaft 15. The unwinding shaft 15 can also rotate together with the roll body R1 by being pulled by the conveying section 16 described later through the medium 99.

[0020] The processing device 11 includes a conveying unit 16 . The conveying unit 16 is configured to convey the medium 99 . The conveying unit 16 includes, for example, one or more rollers. The conveying unit 16 conveys the medium 99 unwound from the unwinding unit 14 .

[0021] The processing device 11 includes a processing unit 17. The processing unit 17 is configured to perform processing on the medium 99. The processing unit 17 performs processing on the medium 99 transported by the transport unit 16. In one example, the processing unit 17 is configured to print on the medium 99. The processing unit 17 has, for example, a head that ejects liquid. The processing unit 17 prints an image on the medium 99 by ejecting liquid onto the medium 99.

[0022] The processing device 11 includes a support portion 18. The support portion 18 supports the medium 99. The support portion 18 is opposed to the processing portion 17. Specifically, the support portion 18 is located directly below the processing portion 17. The support portion 18 supports a portion of the medium 99 to be processed by the processing portion 17. The support portion 18 supports the medium 99 transported by the transport portion 16.

[0023] The processing device 11 includes a cutting unit 19. The cutting unit 19 is configured to cut the medium 99. The cutting unit 19 cuts the medium 99 processed by the processing unit 17. The cutting unit 19 has, for example, a rotating blade. The cutting unit 19 cuts the long medium 99 unwound from the roll body R1 to generate a single medium 99.

[0024] The processing device 11 includes a discharge unit 20. The discharge unit 20 is configured to discharge the medium 99. The discharge unit 20 includes, for example, one or more rollers. The discharge unit 20 discharges the medium 99 cut by the cutting unit 19 to the outside of the housing 12. The discharge unit 20 discharges the medium 99 to the medium loading device 21 through the discharge port 13. The discharge unit 20 discharges the medium 99 along the first direction D1.

[0025] Media loading device

[0026] Next, the medium loading device 21 will be described.

[0027] The medium loading device 21 receives the medium 99 discharged from the processing device 11. The medium 99 discharged from the processing device 11 is loaded on the medium loading device 21. The medium 99 unwound from the roll body R1 is loaded on the medium loading device 21. A curl mark is left on the medium 99. Therefore, the medium 99 is prone to curling on the medium loading device 21. In detail, the medium 99 is prone to curling as in the posture when it was once wound on the roll body R1. In one example, the medium 99 is prone to curling in an upward convex manner. In particular, the top portion and the rear end portion of the medium 99 are prone to curling. In the medium loading device 21, if the medium 99 curls, it may cause the medium 99 to be blocked. Therefore, the medium loading device 21 needs to receive the medium 99 from the processing device 11 while suppressing the curling of the medium 99. In addition, the medium loading device 21 needs to suppress the curling of the loaded medium 99.

[0028] like Figure 2 As shown, the medium loading device 21 includes a leg portion 22. The leg portion 22 is in contact with the floor surface.

[0029] The medium loading device 21 includes a main body 23. The main body 23 is attached to the leg 22. The main body 23 is supported by the leg 22. The main body 23 is located on the leg 22. The main body 23 is configured to support a loading unit 26 described later.

[0030] The main body 23 has two side frames. Specifically, the main body 23 has a first side frame 24 and a second side frame 25. The first side frame 24 and the second side frame 25 extend along a first direction D1. The first direction D1 is a direction in which the loading portion 26 extends. The first direction D1 is a direction that indicates the length from the rear end to the front end of the medium 99.

[0031] The first side frame 24 and the second side frame 25 are arranged in the second direction D2. The second direction D2 is a direction different from the first direction D1. The second direction D2 is a direction intersecting the first direction D1. The second direction D2 is a direction that serves as an indicator of the width of the medium 99. The first side frame 24 and the second side frame 25 are arranged in the second direction D2 in sequence. The first side frame 24 and the second side frame 25 are opposite to each other in the second direction D2.

[0032] The first side frame 24 and the second side frame 25 can guide the side ends of the medium 99. That is, the first side frame 24 and the second side frame 25 can respectively guide the ends of the medium 99 in the second direction D2. In one example, the medium 99 can be discharged from the processing device 11 to the medium loading device 21 in such a manner that the side ends of the medium 99 are along the first side frame 24. In the case where the medium 99 with a smaller width is discharged from the processing device 11 along the first side frame 24, there may be a case where the first side frame 24 guides the side ends of the medium 99, while the second side frame 25 does not guide the side ends of the medium 99. The medium 99 can also be discharged from the processing device 11 to the medium loading device 21 in such a manner that the center of the medium 99 is aligned with the middle position of the first side frame 24 and the second side frame 25.

[0033] The medium loading device 21 includes a loading unit 26. The loading unit 26 is attached to the first side frame 24 and the second side frame 25. The medium 99 is loaded on the loading unit 26. The loading unit 26 receives the medium 99 discharged from the processing device 11. The loading unit 26 supports the medium 99 from below.

[0034] The loading section 26 extends in the first direction D1. Therefore, the medium 99 is loaded on the loading section 26 in a posture extending in the first direction D1. The medium 99 is loaded on the loading section 26 by moving from the processing device 11 in the first direction D1. In one example, the first direction D1 is a direction facing obliquely downward. Therefore, the medium 99 moves in a manner of sliding on the loading section 26 by gravity. As a result, the medium 99 is smoothly loaded on the loading section 26.

[0035] The mounting portion 26 has a bridge member 27. The bridge member 27 extends in the second direction D2. The bridge member 27 is bridged on the first side frame 24 and the second side frame 25. Thus, the rigidity of the main body 23 is improved.

[0036] like Figure 2 as well as Figure 3 As shown, the loading portion 26 has more than one supporting member 28. In one example, the loading portion 26 has three supporting members 28. The three supporting members 28 are arranged in the second direction D2. The three supporting members 28 can also be integrally formed. For example, the loading portion 26 can have a supporting member 28 that is elongated in the second direction D2.

[0037] The support member 28 is attached to the installation member 27. The support member 28 is supported by the installation member 27. The support member 28 is located on the installation member 27. The support member 28 is, for example, a rectangular plate member.

[0038] The support member 28 supports the medium 99 discharged from the processing device 11. The support member 28 receives the leading end of the medium 99 discharged from the discharge port 13. The support member 28 guides the leading end of the medium 99 into the medium loading device 21. The support member 28 supports the trailing end of the medium 99 loaded on the loading unit 26.

[0039] The support member 28 has a support surface 29. The support surface 29 is a surface that supports the medium 99. The support surface 29 is a surface of the support member 28 that faces upward. The support member 28 receives the medium 99 through the support surface 29. Since the support member 28 receives the tip of the medium 99 using the support surface 29, the posture of the medium 99 is easy to be stabilized. Therefore, the support member 28 is easy to guide the medium 99 in the first direction D1. If the support member 28 receives the tip of the medium 99 with a small area, the posture of the medium 99 is difficult to be stabilized, and the tip of the medium 99 may be easy to curl.

[0040] The support member 28 supports the portion of the medium 99 located in the support area A1 in the second direction D2. The support area A1 is the area occupied by the support member 28 in the second direction D2. That is, when the loading section 26 has one support member 28, the length of the support area A1 is the width of the support member 28. When the loading section 26 has a plurality of support members 28, the length of the support area A1 is the total width of the plurality of support members 28. The greater the length of the support area A1, the easier it is for the support member 28 to stably receive the top end of the medium 99.

[0041] The mounting part 26 has two convex parts. Specifically, the mounting part 26 has a first convex part 31 and a second convex part 32. The first convex part 31 and the second convex part 32 are mounted on the mounting part 27. The first convex part 31 and the second convex part 32 are supported by the mounting part 27. The first convex part 31 and the second convex part 32 are located on the mounting part 27.

[0042] The first convex member 31 and the second convex member 32 are arranged side by side with the support member 28 in the second direction D2. The first convex member 31 and the second convex member 32 are respectively located at both sides of the support member 28 in the second direction D2. In detail, the first convex member 31 is located between the first side frame 24 and the support member 28 in the second direction D2. The second convex member 32 is located between the second side frame 25 and the support member 28 in the second direction D2. The first convex member 31, the support member 28, and the second convex member 32 are arranged in sequence in the second direction D2. The first convex member 31 and the second convex member 32 are located outside the support area A1 in the second direction D2.

[0043] The first convex member 31 and the second convex member 32 receive the medium 99. Specifically, the first convex member 31 and the second convex member 32 receive the tip of the medium 99 discharged from the processing device 11 together with the support member 28.

[0044] The first convex member 31 and the second convex member 32 support the medium 99. For example, the first convex member 31 and the second convex member 32 support the rear end of the medium 99 placed on the placement unit 26 together with the support member 28.

[0045] The first convex member 31 and the second convex member 32 are configured to protrude upward relative to the support member 28. Therefore, the first convex member 31 and the second convex member 32 support the medium 99 in a manner of lifting the medium 99 relative to the support member 28. When the width of the medium 99 is small, there is a case where the first convex member 31 supports the medium 99, while the second convex member 32 does not support the medium 99. The interval between the first convex member 31 and the second convex member 32 is smaller than the width of the largest medium 99 that can be loaded on the medium loading device 21.

[0046] like Figure 3 as well as Figure 4 As shown, the first convex member 31 has a first convex surface 33. The first convex surface 33 is a surface facing upward. The second convex member 32 has a second convex surface 34. The second convex surface 34 is a surface facing upward. The first convex surface 33 and the second convex surface 34 support the medium 99 discharged from the processing device 11 together with the support surface 29. The first convex surface 33 and the second convex surface 34 support the medium 99 loaded on the loading portion 26 together with the support surface 29.

[0047] The first convex surface 33 and the second convex surface 34 are located above the support surface 29. The first convex surface 33 and the second convex surface 34 can be located at the same height as each other. The portion of the medium 99 supported by the first convex member 31 and the second convex member 32 is lifted higher than the portion supported by the support member 28. Thus, a strip extending in the first direction D1 is formed on the medium 99 in a manner intersecting the curl mark. The medium 99 is bent in the second direction D2 by the strip. Thus, the possibility of the medium 99 curling due to the curl mark can be reduced. In particular, the possibility of the portion of the medium 99 loaded on the loading portion 26 supported by the first convex member 31 or the second convex member 32 curling due to the curl mark can be reduced.

[0048] The first convex member 31 faces the first side frame 24. The first convex member 31 has a first facing surface 35. The first facing surface 35 faces the first side frame 24. In one example, the first facing surface 35 faces the opposite direction to the second direction D2.

[0049] The first convex member 31 is provided at a distance from the first side frame 24 in the second direction D2. Therefore, due to the flexibility of the medium 99, the side end of the medium 99 may fall between the first side frame 24 and the first convex member 31. In other words, if the medium 99 is easily flexible, the medium 99 droops along the first opposing surface 35. The medium 99 bends downward along the first convex member 31.

[0050] The second convex member 32 faces the second side frame 25. The second convex member 32 has a second facing surface 36. The second facing surface 36 faces the second side frame 25. In one example, the second facing surface 36 faces the second direction D2.

[0051] The second convex member 32 is provided at a distance from the second side frame 25 in the second direction D2. Therefore, when the medium 99 is supported by the second convex member 32, the side end of the medium 99 may fall between the second side frame 25 and the second convex member 32 due to the flexibility of the medium 99. In other words, if the medium 99 is easily flexible, the medium 99 droops along the second opposing surface 36. The medium 99 bends downward along the second convex member 32.

[0052] If the medium 99 is of large width, both side ends of the medium 99 will bend along the first convex part 31 and the second convex part 32, so that the medium 99 bends in a wave-like manner. Figure 3 as well as Figure 4 As shown by the dotted line, when viewed from the first direction D1, the medium 99 is bent into an M-shape by the support member 28, the first convex member 31, and the second convex member 32. This makes it easy to form stripes extending in the first direction D1 on the medium 99.

[0053] like Figure 2 As shown, the loading part 26 has more than one loading part. In one example, the loading part 26 has a first loading part 41 and a second loading part 42. The loading part extends from the supporting part 28 along the first direction D1. In detail, the first loading part 41 extends from the supporting part 28 to the first direction D1. The second loading part 42 extends from the first loading part 41 to the first direction D1. The supporting part 28, the first loading part 41 and the second loading part 42 are arranged in the first direction D1 in sequence. The medium 99 guided by the supporting part 28 is loaded on the loading part. The loading part supports the medium 99 received by the supporting part 28. The loading part supports the medium 99 together with the supporting part 28, the first convex part 31 and the second convex part 32.

[0054] like Figure 2 as well as Figure 5As shown, the first loading member 41 and the second loading member 42 may also be configured to be foldable. In one example, the second loading member 42 is configured to be foldable to be located below the first loading member 41. That is, the second loading member 42 is configured to be stored below the first loading member 41. The second loading member 42 is connected to the first loading member 41 in a rotatable manner. The second loading member 42 rotates relative to the first loading member 41 with the connection portion between the first loading member 41 and the second loading member 42 as an axis, thereby Figure 2 The state shown is shifted to Figure 5 When the second loading member 42 is folded, the first loading member 41 and the second loading member 42 are not arranged in the first direction D1. By folding the second loading member 42, the occupied space of the medium loading device 21 can be reduced.

[0055] like Figure 6 As shown, the loading component has a plurality of ribs. Specifically, the first loading component 41 has a plurality of first ribs 43. In one example, the first loading component 41 has five first ribs 43. The second loading component 42 has a plurality of second ribs 44. In one example, the second loading component 42 has five second ribs 44. The plurality of ribs are arranged at intervals in the second direction D2. The plurality of ribs support the medium 99. The loading component supports the medium 99 guided by the supporting component 28. Therefore, even if the loading component supports the medium 99 by a rod-shaped component such as a rib, the posture of the medium 99 can be maintained stable.

[0056] The loading component has a connecting component. In detail, the first loading component 41 has a first connecting component 45. The second loading component 42 has a second connecting component 46. The connecting component extends along the second direction D2. The connecting component connects a plurality of ribs. The first connecting component 45 connects a plurality of first ribs 43. The first connecting component 45 connects the top ends of the plurality of first ribs 43. The second connecting component 46 connects a plurality of second ribs 44. The second connecting component 46 connects the top ends of the plurality of second ribs 44. The second connecting component 46 may also contact the floor surface. Thus, the posture of the second loading component 42 is stabilized.

[0057] The first rib 43 extends in the first direction D1. The first rib 43 is mounted on the mounting member 27 or the supporting member 28. In one example, the base end of the first rib 43 is mounted on the mounting member 27 or the supporting member 28. The first rib 43 may be mounted on the mounting member 27 or the supporting member 28 so as to be rotatable with its base end as an axis. The plurality of first ribs 43 are symmetrically arranged in the second direction D2, for example, with the center of the first mounting member 41 as a reference. The plurality of first ribs 43 are arranged, for example, at equal intervals.

[0058] The plurality of first ribs 43 are arranged at intervals in the second direction D2. The plurality of first ribs 43 support the medium 99. The medium 99 is supported by the plurality of first ribs 43 to be in a wavy state. As a result, the medium 99 is less likely to curl. The portion of the medium 99 supported by the plurality of first ribs 43 is curved more finely than the portion supported by the support member 28.

[0059] The first rib 43 is located below the first convex member 31 and the second convex member 32. Specifically, the first rib 43 is located below the first convex surface 33 and the second convex surface 34. The first rib 43 extends below the first convex member 31 and the second convex member 32. That is, the first convex member 31 and the second convex member 32 are provided so that the first convex surface 33 and the second convex surface 34 are located above the first rib 43. Thus, the medium 99 easily moves from the support member 28 to the first rib 43.

[0060] like Figure 3 as well as Figure 4 As shown, the plurality of first ribs 43 include at least one first rib 43 mounted on the erection member 27 and at least one first rib 43 mounted on the support member 28. In one example, the second and fourth first ribs 43 in the second direction D2 among the five first ribs 43 are mounted on the erection member 27. The first, third, and fifth first ribs 43 in the second direction D2 among the five first ribs 43 are mounted on the support member 28. The plurality of first ribs 43 may be mounted only on the erection member 27 or only on the support member 28.

[0061] The plurality of first ribs 43 may include at least one first rib 43 located at a first height and at least one first rib 43 located at a second height different from the first height. In one example, the first rib 43 installed on the mounting member 27 is located at a height different from the first rib 43 installed on the support member 28. Specifically, the first rib 43 installed on the mounting member 27 is located at a lower position than the first rib 43 installed on the support member 28. Thus, as Figure 3 as well as Figure 4 As indicated by the two-dot chain line, when viewed from the first direction D1 , the medium 99 is curved in a corrugated shape by the plurality of first ribs 43 .

[0062] like Figure 6As shown, the first loading member 41 supports the portion of the medium 99 located in the first loading area A2 in the second direction D2. The first loading area A2 is the area occupied by the plurality of first ribs 43 in the second direction D2. That is, the first loading area A2 is the area between the two first ribs 43 located at the ends in the second direction D2. In one example, the first loading area A2 is the area from the first first rib 43 located in the second direction D2 to the fifth first rib 43 among the five first ribs 43. The smaller the length of the first loading area A2, the more the side ends of the medium 99 sag.

[0063] The first loading area A2 is smaller than the supporting area A1. Therefore, the side ends of the medium 99 in the first loading part 41 droop more significantly than in the supporting part 28. That is, the loading part 26 supports the medium 99 in such a manner that the drooping amount of the side ends increases as it moves toward the first direction D1. As a result, it is easy to form a drooping area on the medium 99. Figure 6 The curved strips L1 extending along the first direction D1 as shown by the double-dashed lines in the figure. Specifically, the two side ends of the medium 99 sag downward, thereby forming two curved strips L1 on the medium 99. The two curved strips L1 extend in such a manner that the interval between the curved strips L1 decreases as they approach the first direction D1. By greatly sag the side ends of the medium 99, the possibility of the medium 99 curling due to curl marks can be reduced.

[0064] The second rib 44 extends in the first direction D1. The second rib 44 is mounted on the first loading member 41. In detail, the second rib 44 is mounted on the first connecting member 45. In one example, the base end of the second rib 44 is mounted on the first connecting member 45. In one example, the second rib 44 is mounted on the first connecting member 45 in a manner that allows rotation about the base end thereof. The second rib 44 is supported by the first connecting member 45 in a manner that allows rotation relative to the first connecting member 45. Thus, the second loading member 42 can be folded relative to the first loading member 41. For example, a plurality of second ribs 44 are arranged symmetrically in the second direction D2 with the center of the second loading member 42 as a reference.

[0065] The second rib 44 may be located below the first rib 43. In one example, the second rib 44 extends below the first rib 43. Thus, the medium 99 easily moves from the first rib 43 to the second rib 44.

[0066] The plurality of second ribs 44 may include a plurality of second ribs 44 located at different heights, similarly to the first ribs 43. The plurality of second ribs 44 may include one or more second ribs 44 located at a third height and one or more second ribs 44 located at a fourth height different from the third height. In one example, the first, third, and fifth second ribs 44 located in the second direction D2 among the five second ribs 44 are located at a higher position than the second and fourth second ribs 44. The medium 99 is bent in a wave-like manner by the plurality of second ribs 44.

[0067] The plurality of second ribs 44 are arranged at intervals smaller than the intervals between the first ribs 43. That is, the intervals between the second ribs 44 are smaller than the intervals between the first ribs 43. In detail, the plurality of second ribs 44 include a plurality of second ribs 44 arranged at intervals smaller than the intervals between the first ribs 43. In one example, the interval between the first second rib 44 and the second second rib 44 in the second direction D2 among the five second ribs 44 is smaller than the intervals between the first ribs 43. In addition, the interval between the fourth second rib 44 and the fifth second rib 44 in the second direction D2 among the five second ribs 44 is smaller than the intervals between the first ribs 43. As a result, the portion of the medium 99 supported by the plurality of second ribs 44 is bent more finely than the portion supported by the plurality of first ribs 43. As a result, the medium 99 becomes less likely to curl. The plurality of second ribs 44 may also be arranged at equal intervals in the second direction D2.

[0068] The second loading member 42 supports the portion of the medium 99 located in the second loading area A3 in the second direction D2. The second loading area A3 is the area occupied by the plurality of second ribs 44 in the second direction D2. That is, the second loading area A3 is the area between the two second ribs 44 located at the ends in the second direction D2. In one example, the second loading area A3 is the area from the first second rib 44 to the fifth second rib 44 in the second direction D2 among the five second ribs 44.

[0069] The second loading area A3 is smaller than the first loading area A2. Therefore, the side ends of the medium 99 in the second loading part 42 droop more significantly than in the first loading part 41. That is, the loading part 26 supports the medium 99 in such a manner that the drooping amount of the side ends increases as it moves toward the first direction D1. As a result, it is easy to form a drooping shape on the medium 99. Figure 6The curved strip L1 as shown by the double-dashed line in the figure. When the medium 99 moves along the first direction D1 on the loading portion 26, the top end of the medium 99 is prone to curling due to the curl mark. This is because, when the medium 99 moves, the rear end of the medium 99 is held by the discharge portion 20. That is, the rear end of the medium 99 is held by the discharge portion 20, while the top end of the medium 99 is a free end. Therefore, when the medium 99 moves along the first direction D1 on the loading portion 26, the top end of the medium 99 is prone to curling compared to the rear end of the medium 99. In contrast, by supporting the medium 99 in such a manner that the side end of the medium 99 droops more toward the first direction D1, the possibility of the medium 99 curling due to the curl mark can be reduced.

[0070] like Figure 2 As shown, the medium loading device 21 may include an auxiliary portion 51. The auxiliary portion 51 is configured to assist the loading portion 26. The auxiliary portion 51 is configured to support the loading component. The auxiliary portion 51 is mounted on the foot portion 22. The auxiliary portion 51 is mounted on the loading component. In one example, the auxiliary portion 51 is mounted on the first loading component 41. The auxiliary portion 51 is mounted on the first connecting component 45. In the first loading component 41 and the second loading component 42, since they are long strips in the first direction D1, the load on the connection portion thereof tends to increase. By supporting the first connecting component 45 with the auxiliary portion 51, the load on the connection portion can be reduced. Therefore, the postures of the first loading component 41 and the second loading component 42 are stable.

[0071] The medium loading device 21 includes a stopper 52. The stopper 52 is mounted on the loading portion 26. For example, the stopper 52 is mounted on the loading member. The stopper 52 is mounted on the first loading member 41 or the second loading member 42. The stopper 52 is mounted on the rib. That is, the stopper 52 is mounted on the first rib 43 or the second rib 44. In one example, the stopper 52 is mounted on the first rib 43. The stopper 52 may also be mounted on the supporting member 28.

[0072] The stopper 52 contacts the tip of the medium 99. Thus, the stopper 52 stops the medium 99. The stopper 52 stops the medium 99 that is traveling in the first direction D1 on the loading portion 26. Thus, the possibility of the medium 99 falling from the loading portion 26 can be reduced.

[0073] The blocking member 52 may be installed on the loading portion 26 in a manner that allows it to be displaced along the first direction D1. The blocking member 52 may be installed in a manner that allows it to be moved along the rib. The blocking member 52 may also be configured to be removable relative to the rib. Thus, the blocking member 52 can be displaced according to the length of the discharged medium 99. For example, when the length of the medium 99 is large, the blocking member 52 can be displaced in the first direction D1. The blocking member 52 can contact the top end of the medium 99 at any position in the first direction D1. The blocking member 52 can block the medium 99 at any position in the first direction D1.

[0074] The stopper 52 has a mounting portion 53 mounted on the rib. The mounting portion 53 sandwiches the rib. Thus, the stopper 52 is mounted on the rib. The mounting portion 53 is configured to sandwich the rib or to release the rib. Therefore, the stopper 52 is configured to be attachable to and detachable from the rib. Thus, the stopper 52 can be displaced along the first direction D1.

[0075] The medium loading device 21 includes a restriction portion 61. The restriction portion 61 is located above the loading portion 26. The restriction portion 61 is configured to press the medium 99 loaded on the loading portion 26 from above. By pressing the medium 99, the restriction portion 61 can reduce the possibility of the medium 99 curling.

[0076] The limiting portion 61 has one or more connecting parts. In one example, the limiting portion 61 has a first connecting part 62 and a second connecting part 63. The connecting part extends along the second direction D2. The connecting part is connected to the first side frame 24 and the second side frame 25. The connecting part is mounted on the first side frame 24 and the second side frame 25. The first connecting part 62 and the second connecting part 63 are arranged in sequence in the first direction D1.

[0077] The restriction portion 61 has one or more restriction units. For example, the restriction portion 61 has one or more first restriction units 64 and one or more second restriction units 65. In one example, the restriction portion 61 has three first restriction units 64 and one second restriction unit 65.

[0078] The limiting unit presses the medium 99 loaded on the loading member. The first limiting unit 64 presses the medium 99 loaded on the first loading member 41. The first limiting unit 64 is located above the first loading member 41. The first limiting unit 64 is installed on the first connecting member 62 and the second connecting member 63. The second limiting unit 65 presses the medium 99 loaded on the second loading member 42. The second limiting unit 65 is located above the second loading member 42. The second limiting unit 65 is installed on the second connecting member 63.

[0079] The three first limiting units 64 are arranged at intervals in the second direction D2. The three first limiting units 64 are arranged symmetrically in the second direction D2 with the center of the first mounting member 41 as a reference. The three first limiting units 64 are arranged at equal intervals, for example.

[0080] The first limiting unit 64 is provided in a manner opposed to the first rib 43. That is, when viewed from above, the first limiting unit 64 overlaps with the first rib 43. Thus, the first limiting unit 64 can press the portion of the medium 99 that is lifted by the first rib 43. As a result, the possibility of clogging of the medium 99 can be reduced. In one example, three first limiting units 64 are respectively opposed to the first rib 43 located at the first, third, and fifth of the five first ribs 43 in the second direction D2.

[0081] like Figure 7 as well as Figure 8 As shown, the first limiting unit 64 has a first mounting member 66 and more than one first limiting member 67. In one example, the first limiting unit 64 has a first mounting member 66 and more than one first limiting member 67.

[0082] The first mounting member 66 extends in the first direction D1. The base end of the first mounting member 66 is mounted on the first connecting member 62. The top end of the first mounting member 66 is mounted on the second connecting member 63.

[0083] The first mounting member 66 is provided so as to face the first rib 43 .

[0084] The first restricting member 67 is mounted on the first mounting member 66. The first restricting member 67 is mounted so as to be close to the first mounting member 41 from the first mounting member 66. The first restricting member 67 is mounted so as to protrude downward from the first mounting member 66.

[0085] The first limiting member 67 presses the medium 99 by contacting the medium 99. The first limiting member 67 has a limiting surface that contacts the medium 99 from above. That is, the first limiting member 67 has a first limiting surface 68. The first limiting surface 68 extends in the first direction D1. The first limiting member 67 is mounted on the first mounting member 66 in such a manner that the first limiting surface 68 is parallel to the first rib 43.

[0086] The plurality of first limiting members 67 are arranged along the first direction D1 on the first mounting member 66. The plurality of first limiting members 67 are arranged along the first direction D1 in such a manner that the first limiting surfaces 68 of the first limiting members 67 are connected when viewed from the second direction D2. The plurality of first limiting surfaces 68 are provided in a continuous manner when viewed from the second direction D2. Thus, the possibility of the medium 99 entering into the gaps between the first limiting members 67 can be reduced. Therefore, the possibility of the medium 99 being blocked can be reduced.

[0087] The first limiting member 67 may be mounted so as to be swingable relative to the first mounting member 66. In one example, the first limiting member 67 swings relative to the first mounting member 66 so that the first limiting surface 68 faces the first direction D1. The first limiting member 67 is a blade. The first limiting member 67 swings so that the first limiting surface 68 faces the first direction D1 by receiving a reaction force from the medium 99. Thus, the possibility of clogging of the medium 99 can be reduced by strongly contacting the first limiting member 67 with the medium 99. For example, the plurality of first limiting members 67 swing individually.

[0088] The first limiting unit 64 may have more than one rotating member. In one example, the first limiting unit 64 has a plurality of first rotating members 69. The first rotating member 69 is a roller. The first rotating member 69 is mounted on the first limiting member 67. The first rotating member 69 rotates relative to the first limiting member 67. The first rotating member 69 is provided so as to protrude from the first limiting surface 68 toward the first loading member 41 when viewed from the second direction D2. As the first limiting member 67 presses the medium 99, the first rotating member 69 contacts the medium 99. The first rotating member 69 rotates by contacting the medium 99. The first rotating member 69 guides the medium 99 in the first direction D1 by rotating. The first rotating member 69 can reduce the possibility of clogging of the medium 99.

[0089] like Figure 2As shown, the second limiting unit 65 is arranged in a manner opposite to the second rib 44. That is, when viewed from above, the second limiting unit 65 overlaps with the second rib 44. As a result, the second limiting unit 65 can press the portion of the medium 99 that is tilted due to the second rib 44. As a result, the possibility of the medium 99 being blocked can be reduced. In one example, the second limiting unit 65 is opposite to the second rib 44 located fourth in the second direction D2 among the five second ribs 44. This is to reduce the possibility of the medium 99 with a smaller width being curled. In the case of the medium 99 with a smaller width, the side end of the medium 99 may not sag sufficiently. In detail, sometimes the side end of the medium 99 located on the second direction D2 side compared with the second rib 44 located fifth in the second direction D2 among the five second ribs 44 does not sag sufficiently. In such a case, it is difficult to form the bending strip L1, so that the medium 99 may be tilted. On the other hand, the second limiting unit 65 is arranged to be offset from the center of the second loading member 42 in the second direction D2, thereby being able to press a portion of the medium 99 that is prone to curling. This can reduce the possibility of curling of the medium 99 with a small width.

[0090] The second restricting unit 65 includes one or more second restricting members 70. In one example, the second restricting unit 65 includes one second restricting member 70. The second restricting unit 65 may include a plurality of second restricting members 70 similarly to the first restricting unit 64.

[0091] The second limiting member 70 extends in the first direction D1. The second limiting member 70 extends in a long manner along the second rib 44. The second limiting member 70 is mounted on the second connecting member 63. In detail, the base end of the second limiting member 70 is supported by the second connecting member 63. The top end of the second limiting member 70 is supported by the second loading member 42. In one example, the top end of the second limiting member 70 is supported by the second connecting member 46. As a result, the posture of the second limiting member 70 is stabilized.

[0092] The second restricting member 70 may be rotatably mounted to the second connecting member 63. When the second loading member 42 is folded, the second restricting member 70 can be retracted onto the first restricting unit 64 by rotating about the portion mounted to the second connecting member 63 as an axis.

[0093] like Figure 7 as well as Figure 8As shown, the second limiting member 70 is disposed in a manner opposite to the second rib 44. The second limiting member 70 presses the warped medium 99 by contacting the medium 99. The second limiting member 70 has a limiting surface for pressing the medium 99. That is, the second limiting member 70 has a second limiting surface 71. The second limiting surface 71 extends along the first direction D1. The second limiting surface 71 is parallel to the second rib 44.

[0094] The second limiting unit 65 may have more than one rotating member. In one example, the second limiting unit 65 has a plurality of second rotating members 72. The second rotating member 72 is a roller. The second rotating member 72 is mounted on the second limiting member 70. The second rotating member 72 rotates relative to the second limiting member 70. The second rotating member 72 is arranged so as to protrude from the second limiting surface 71 toward the second loading member 42 when viewed from the second direction D2. As the second limiting member 70 presses the medium 99, the second rotating member 72 contacts the medium 99. The second rotating member 72 is able to rotate by contacting the medium 99. The second rotating member 72 guides the medium 99 to the first direction D1 by rotating. The possibility of clogging of the medium 99 can be reduced by the second rotating member 72.

[0095] Function and effect

[0096] Next, the operation and effects of the above-described embodiment will be described.

[0097] (1) The first convex surface 33 and the second convex surface 34 are located above the support surface 29. The medium 99 may be easily curled in the first direction D1 due to its curling mark. According to the above structure, the first convex member 31 and the second convex member 32 support the medium 99 in a manner of lifting the medium 99 relative to the support member 28. As a result, the medium 99 is bent in a manner that the bending line L1 extends in the first direction D1. As a result, the possibility of the medium 99 curling due to the curling mark can be reduced.

[0098] (2) The first loading member 41 has a plurality of first ribs 43 extending in the first direction D1. According to the above structure, the medium 99 is supported by the plurality of first ribs 43, so that it is easy to be in a state of undulating in the second direction D2. Thus, the possibility of the medium 99 curling due to curl marks can be reduced.

[0099] (3) The first convex member 31 and the second convex member 32 are provided so that the first convex surface 33 and the second convex surface 34 are located above the plurality of first ribs 43. With the above configuration, the medium 99 can easily travel in the first direction D1 in the loading section 26.

[0100] (4) The intervals between the second ribs 44 are smaller than the intervals between the first ribs 43. According to the above structure, the medium 99 is supported by the plurality of second ribs 44 and becomes a more finely corrugated state than the portion supported by the plurality of first ribs 43. That is, the portion of the medium 99 supported by the plurality of second ribs 44 becomes a more finely corrugated state than the portion supported by the plurality of first ribs 43. Thus, the possibility of the medium 99 curling due to the curl mark can be reduced.

[0101] (5) The second loading member 42 is configured to be stored below the first loading member 41 by rotating relative to the first loading member 41 about the connection portion between the first loading member 41 and the second loading member 42. According to the above configuration, the second loading member 42 is stored below the first loading member 41, so that the space occupied by the medium loading device 21 can be reduced. As a result, the usability of the medium loading device 21 is improved.

[0102] (6) The length of the second loading area A3 is shorter than that of the first loading area A2. According to the above structure, the medium 99 is easily bent in such a way that the bending line L1 extends from the first convex part 31 and the second convex part 32 to the second loading part 42. Thus, the possibility of the medium 99 being curled due to the curl mark can be reduced.

[0103] (7) The medium loading device 21 includes the stopper 52, which is mounted on the loading portion 26 and contacts the tip of the medium 99. According to the above structure, the stopper 52 contacts the tip of the medium 99, so that the medium 99 stops on the loading portion 26. Therefore, the possibility of the medium 99 falling from the loading portion 26 can be reduced.

[0104] (8) The stopper 52 is mounted on the loading portion 26 so as to be displaceable in the first direction D1. According to the above configuration, the stopper 52 can be displaced according to the length of the medium 99. Thus, the possibility of the medium 99 falling from the loading portion 26 can be reduced.

[0105] (9) The plurality of first limiting surfaces 68 are provided in a continuous manner when viewed from the second direction D2. According to the above structure, since the plurality of first limiting surfaces 68 are provided in a continuous manner in the first direction D1, the medium 99 does not enter the gap between the first limiting members 67. Therefore, the possibility of clogging of the medium 99 can be reduced.

[0106] (10) The plurality of first limiting members 67 are swung relative to the first mounting member 66 so that the first limiting surfaces 68 face the first direction D1. In the medium loading device 21, a medium 99 with relatively high rigidity may be loaded. In such a case, the medium 99 with relatively high rigidity may be damaged due to strong contact with the first limiting members 67. According to the above configuration, the possibility that the medium 99 may be strongly contacted with the first limiting members 67 can be reduced by the first limiting members 67 being pushed up by the medium 99.

[0107] (11) The first direction D1 is a direction extending obliquely downward. According to the above structure, the loading portion 26 extends obliquely downward. Therefore, the medium 99 discharged from the processing device 11 is easy to slide on the loading portion 26 along the first direction D1 due to gravity. Therefore, the loading portion 26 is easy to load the medium 99.

[0108] Change Example

[0109] The above-described embodiment can be modified and implemented as follows. The above-described embodiment and the following modified examples can be implemented in combination with each other within the scope of no technical contradiction.

[0110] The first restricting means 64 may be configured such that the first restricting member 67 is directly attached to the connecting member, similarly to the second restricting means 65. For example, the first restricting member 67 may be configured such that it does not swing, similarly to the second restricting member 70.

[0111] The second restricting means 65 may include a mounting member similarly to the first restricting means 64. For example, the second restricting member 70 may be configured to swing similarly to the first restricting member 67.

[0112] Technical Thought

[0113] The following describes the technical ideas and effects that can be understood from the above-mentioned embodiments and modified examples.

[0114] (A) A medium loading device loads a medium discharged from a processing device, the medium loading device having a loading portion, the loading portion extending in a first direction and loading the medium, the loading portion having a supporting member and a first convex member and a second convex member, the supporting member supporting the medium, the first convex member and the second convex member being located at both sides of the supporting member in a second direction different from the first direction, the supporting member having a supporting surface supporting the medium, the first convex member having a first convex surface supporting the medium, the second convex member having a second convex surface supporting the medium, the first convex surface and the second convex surface being located above the supporting surface. The medium is sometimes prone to curling in the first direction due to its curling mark. According to the above structure, the first convex member and the second convex member support the medium in a manner of lifting the medium relative to the supporting member. As a result, the medium is bent in a manner of extending in the first direction in a strip. As a result, the possibility of the medium curling due to the curling mark can be reduced.

[0115] (B) In the above-mentioned medium loading device, the loading portion may include a loading member extending from the supporting member in the first direction, the loading member includes a plurality of ribs extending in the first direction, and the plurality of ribs are arranged at intervals in the second direction. According to the above-mentioned structure, the medium is supported by the plurality of ribs, so that the medium is easily in a wavy state in the second direction. Thus, the possibility of the medium curling due to the curl mark can be reduced.

[0116] (C) In the above medium loading device, the first convex member and the second convex member are provided so that the first convex surface and the second convex surface are located above the plurality of ribs. According to the above configuration, the medium can easily travel in the first direction in the loading section.

[0117] (D) In ​​the above-mentioned medium loading device, it can also be set that the loading component is a first loading component, the multiple ribs are multiple first ribs, the loading part has a second loading component extending from the first loading component to the first direction, the second loading component has multiple second ribs extending along the first direction, the multiple second ribs are arranged at intervals in the second direction, and the intervals between the second ribs are smaller than the intervals between the first ribs. According to the above-mentioned structure, the medium is supported by the multiple second ribs and becomes a more finely wavy state compared with the part supported by the multiple first ribs. That is, the part of the medium supported by the multiple second ribs becomes a more finely wavy state compared with the part supported by the multiple first ribs. Thereby, the possibility of the medium curling due to the curl mark can be reduced.

[0118] (E) In the above-mentioned medium loading device, the second loading member may be connected to the first loading member in a manner that allows rotation relative to the first loading member, and is stored below the first loading member by rotating relative to the first loading member. According to the above-mentioned structure, the second loading member is stored below the first loading member, so that the occupied space of the medium loading device can be reduced. Thus, the usability of the medium loading device is improved.

[0119] (F) In the above-mentioned medium loading device, the width of the area occupied by the plurality of second ribs in the second direction may be smaller than the width of the area occupied by the plurality of first ribs in the second direction. According to the above-mentioned structure, the medium is easily bent in a manner that the strip extends from the first convex part and the second convex part to the second loading part. Thus, the possibility of the medium curling due to the curl mark can be reduced.

[0120] (G) The medium loading device may also include a blocking member, which is mounted on the loading portion and contacts the top of the medium. According to the above structure, the blocking member contacts the top of the medium, so that the medium stops on the loading portion. Therefore, the possibility of the medium falling from the loading portion can be reduced.

[0121] (H) In the above-mentioned medium loading device, the blocking member may be mounted on the loading portion in a manner that allows displacement along the first direction. According to the above-mentioned structure, the blocking member can be displaced according to the length of the medium. Thus, the possibility of the medium falling from the loading portion can be reduced.

[0122] (I) The above-mentioned medium loading device may also include a limiting portion, the limiting portion is located above the loading portion, the limiting portion has a plurality of limiting components arranged in the first direction, the plurality of limiting components respectively have a limiting surface that contacts the medium from above, and the plurality of limiting surfaces are arranged in a continuous manner when viewed from the second direction. According to the above-mentioned structure, since the plurality of limiting surfaces are arranged in a continuous manner in the first direction, the medium will not enter the gap between the limiting components. Therefore, the possibility of the medium being blocked can be reduced.

[0123] (J) In the above-mentioned medium loading device, the limiting portion may include a mounting component for mounting the plurality of limiting components in a manner that they can swing, and the plurality of limiting components may swing relative to the mounting component in a manner that the limiting surface faces the first direction. In the medium loading device, a medium with relatively high rigidity may be loaded. In such a case, the medium may be damaged due to strong contact between the medium and the limiting component. According to the above-mentioned structure, the limiting component is pushed up by the medium, thereby reducing the possibility of strong contact between the medium and the limiting component.

[0124] (K) In the above-mentioned medium loading device, the first direction may also be a direction toward obliquely downward. According to the above-mentioned structure, the loading part extends obliquely downward. Therefore, the medium discharged from the processing device is easy to slide on the loading part along the first direction due to gravity. Therefore, the loading part is easy to load the medium.
