Description

[Technical field]

[0001] The present invention relates to a media loading device. [Background technology]

[0002] Patent Document 1 describes a media loading device on which media discharged from a processing device is loaded. In the media loading device, there is a risk that the media loaded on the loading section will curl due to the curling tendency of the rolled media. If the media curls on the loading section, there is a risk that the media discharged from the processing device will become clogged. For this reason, the media loading device has a regulating member that presses the media from above. This straightens out the curling tendency of the media on the loading section.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0007] Hereinafter, an embodiment of a medium stacking device on which media discharged from a processing device are stacked will be described with reference to the drawings. <Processing equipment> First, the processing device will be described. The processing device is, for example, an inkjet printer that prints images such as characters and photographs by ejecting ink, which is an example of a liquid, onto a medium such as paper or fabric. The processing device is not limited to printing, and may be a device that performs other processes on the medium.

[0008] As shown in FIG. 1, the processing device 11 includes a housing 12. The housing 12 has an outlet 13 through which a medium 99 is discharged. In one example, the outlet 13 opens to the front of the housing 12. The processing device 11 discharges the medium 99 outside the housing 12 through the outlet 13. The processing device 11 discharges the medium 99 forward. The processing device 11 discharges the medium 99 in a first direction D1. The processing device 11 discharges the medium 99 to a medium loading device 21, which will be described later.

[0009] The processing device 11 includes a payout unit 14. The payout unit 14 is configured to pay out the medium 99 from a roll R1. The roll R1 is formed by winding and stacking a long length of the medium 99. The payout unit 14 rotates the roll R1 to unwind the medium 99 from the roll R1. The payout unit 14 pays out the medium 99 unwound from the roll R1.

[0010] The unwinding unit 14 has a unwinding spindle 15. The unwinding spindle 15 is a spindle that supports the roll body R1. The unwinding spindle 15 rotatably supports the roll body R1. The unwinding spindle 15 may support the roll body R1 by contacting the inner circumference of the roll body R1, or may support the roll body R1 by contacting the outer circumference of the roll body R1. The unwinding spindle 15 is attached to the housing 12. The unwinding spindle 15 may rotate together with the roll body R1. The unwinding unit 14 may rotate the roll body R1 by rotating the unwinding spindle 15. The unwinding spindle 15 may rotate together with the roll body R1 by the medium 99 being pulled by the transport unit 16 described later.

[0011] The processing device 11 includes a transport unit 16. The transport unit 16 is configured to transport the medium 99. The transport unit 16 includes, for example, one or more rollers. The transport unit 16 transports the medium 99 fed from the feed unit 14.

[0012] The processing device 11 includes a processing unit 17. The processing unit 17 is configured to apply processing to a medium 99. The processing unit 17 applies processing to 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 the liquid onto the medium 99.

[0013] The processing device 11 includes a support unit 18. The support unit 18 supports a medium 99. The support unit 18 faces the processing unit 17. More specifically, the support unit 18 is located directly below the processing unit 17. The support unit 18 supports a portion of the medium 99 that is to be processed by the processing unit 17. The support unit 18 supports the medium 99 that is to be transported by the transport unit 16.

[0014] 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 that has been processed by the processing unit 17. The cutting unit 19 has, for example, a rotary blade. The cutting unit 19 cuts the long medium 99 unwound from the roll R1 to generate single sheets of medium 99.

[0015] The processing device 11 includes a discharge unit 20. The discharge unit 20 is configured to discharge a 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 through the discharge opening 13 to the medium loading device 21. The discharge unit 20 discharges the medium 99 in a first direction D1.

[0016] <Media loading device> Next, the medium stacking device 21 will be described. The medium loading device 21 receives the medium 99 discharged from the processing device 11. The medium loading device 21 is loaded with the medium 99 discharged from the processing device 11. The medium 99 unwound from the roll body R1 is loaded with the medium loading device 21. The medium 99 has a tendency to curl. Therefore, the medium 99 is likely to curl in the medium loading device 21. More specifically, the medium 99 is likely to curl in the same position as when it was wound and stacked on the roll body R1. In one example, the medium 99 is likely to curl up so as to be convex upward. In particular, the leading end and trailing end of the medium 99 are likely to curl. If the medium 99 curls in the medium loading device 21, the medium 99 may become clogged. Therefore, the medium loading device 21 needs to receive the medium 99 from the processing device 11 while suppressing the medium 99 from curling. In addition, the medium loading device 21 needs to suppress the loaded medium 99 from curling.

[0017] 2, the medium stacking device 21 includes legs 22. The legs 22 come into contact with the floor surface. The medium loading device 21 includes a main body 23. The main body 23 is attached to legs 22. The main body 23 is supported by the legs 22. The main body 23 is located on the legs 22. The main body 23 is configured to support a loading unit 26, which will be described later.

[0018] The main body 23 has two side frames. More 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 in a first direction D1. The first direction D1 is the direction in which the stacking section 26 extends. The first direction D1 is a direction that serves as an index showing the length from the rear end to the front end of the media 99.

[0019] The first side frame 24 and the second side frame 25 are aligned 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 that intersects with 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 aligned in this order in the second direction D2. The first side frame 24 and the second side frame 25 face each other in the second direction D2.

[0020] The first side frame 24 and the second side frame 25 may guide the side edge of the medium 99. That is, the first side frame 24 and the second side frame 25 may each guide the end of the medium 99 in the second direction D2. In one example, the medium 99 may be discharged from the processing device 11 to the medium loading device 21 so that the side edge of the medium 99 is aligned with the first side frame 24. When a narrow medium 99 is discharged from the processing device 11 along the first side frame 24, the first side frame 24 may guide the side edge of the medium 99, while the second side frame 25 may not guide the side edge of the medium 99. The medium 99 may be discharged from the processing device 11 to the medium loading device 21 so that the center of the medium 99 is aligned with the midpoint between the first side frame 24 and the second side frame 25.

[0021] The medium stacking device 21 includes a stacking section 26. The stacking section 26 is attached to the first side frame 24 and the second side frame 25. Media 99 are stacked on the stacking section 26. The stacking section 26 receives the media 99 discharged from the processing device 11. The stacking section 26 supports the media 99 from below.

[0022] The stacking section 26 extends in a first direction D1. Therefore, the media 99 are loaded on the stacking section 26 in a position extending in the first direction D1. The media 99 are loaded on the stacking section 26 by traveling from the processing device 11 in the first direction D1. In one example, the first direction D1 is a direction that faces diagonally downward. Therefore, the media 99 slides along the stacking section 26 due to gravity. This allows the media 99 to be loaded on the stacking section 26 smoothly.

[0023] The loading portion 26 has a bridging member 27. The bridging member 27 extends in the second direction D2. The bridging member 27 is bridgingly mounted on the first side frame 24 and the second side frame 25. This improves the rigidity of the main body portion 23.

[0024] 2 and 3, the loading section 26 has one or more support members 28. In one example, the loading section 26 has three support members 28. The three support members 28 are aligned in the second direction D2. The three support members 28 may be integrally configured. For example, the loading section 26 may have one support member 28 that is elongated in the second direction D2.

[0025] The support member 28 is attached to the bridging member 27. The support member 28 is supported by the bridging member 27. The support member 28 is located on the bridging member 27. The support member 28 is, for example, a rectangular plate member.

[0026] 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 section 26.

[0027] 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 on the support surface 29. By the support member 28 receiving the leading end of the medium 99 on the support surface 29, the posture of the medium 99 is likely to be stabilized. Therefore, the support member 28 is likely to guide the medium 99 in the first direction D1. If the support member 28 receives the leading end of the medium 99 with a small area, the posture of the medium 99 is unlikely to be stabilized, and the leading end of the medium 99 may be likely to curl.

[0028] The support member 28 supports a 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 multiple support members 28, the length of the support area A1 is the total width of the multiple support members 28. The longer the length of the support area A1, the easier it is for the support member 28 to stably receive the leading edge of the medium 99.

[0029] The loading section 26 has two convex members. More specifically, the loading section 26 has a first convex member 31 and a second convex member 32. The first convex member 31 and the second convex member 32 are attached to the installation member 27. The first convex member 31 and the second convex member 32 are supported by the installation member 27. The first convex member 31 and the second convex member 32 are positioned on the installation member 27.

[0030] The first convex member 31 and the second convex member 32 are aligned with the support member 28 in the second direction D2. The first convex member 31 and the second convex member 32 are located on 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 aligned in this order 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.

[0031] The first convex member 31 and the second convex member 32 receive the medium 99. In particular, the first convex member 31 and the second convex member 32, together with the support member 28, receive the leading end of the medium 99 discharged from the processing device 11.

[0032] 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, together with the support member 28, support the rear end of the medium 99 loaded on the loading section 26.

[0033] 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 so as to lift it relative to the support member 28. If the width of the medium 99 is small, while the first convex member 31 supports the medium 99, the second convex member 32 may not support the medium 99. The distance at which the first convex member 31 and the second convex member 32 are disposed is smaller than the width of the maximum medium 99 that the medium loading device 21 can load.

[0034] 3 and 4, 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, together with the support surface 29, support the medium 99 discharged from the processing device 11. The first convex surface 33 and the second convex surface 34, together with the support surface 29, support the medium 99 loaded on the loading section 26.

[0035] 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 may 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 raised higher than the portion supported by the support member 28. As a result, a streak is formed in the medium 99 that extends in the first direction D1 so as to cross the curling tendency. This streak causes the medium 99 to curve in the second direction D2. This reduces the risk of the medium 99 curling due to the curling tendency. In particular, the risk of the portion of the medium 99 supported by the first convex member 31 or the second convex member 32 of the medium 99 loaded on the loading section 26 curling due to the curling tendency is reduced.

[0036] The first protruding member 31 faces the first side frame 24. The first protruding member 31 has a first opposing surface 35. The first opposing surface 35 is a surface that faces the first side frame 24. In one example, the first opposing surface 35 faces in the opposite direction to the second direction D2.

[0037] The first convex member 31 is positioned at a distance from the first side frame 24 in the second direction D2. Therefore, depending on 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 flexible, the medium 99 will hang down along the first opposing surface 35. The medium 99 will curve downward along the first convex member 31.

[0038] The second protruding member 32 faces the second side frame 25. The second protruding member 32 has a second opposing surface 36. The second opposing surface 36 is a surface that faces the second side frame 25. In one example, the second opposing surface 36 faces in the second direction D2.

[0039] The second convex member 32 is positioned 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, depending on the flexibility of the medium 99, the side end of the medium 99 may fall between the second side frame 25 and the second convex member 32. In other words, if the medium 99 is flexible, the medium 99 will hang down along the second opposing surface 36. The medium 99 will bend downward along the second convex member 32.

[0040] If the medium 99 is wide, both side edges of the medium 99 are curved along the first convex member 31 and the second convex member 32, causing the medium 99 to curve in a wavy manner. In one example, as shown by the dashed lines in Figures 3 and 4, when viewed from the first direction D1, the medium 99 is curved in an M shape by the support member 28, the first convex member 31, and the second convex member 32. This makes it easier for streaks extending in the first direction D1 to be formed on the medium 99.

[0041] As shown in FIG. 2, the stacking section 26 has one or more stacking members. In one example, the stacking section 26 has a first stacking member 41 and a second stacking member 42. The stacking members extend in a first direction D1 from the support member 28. More specifically, the first stacking member 41 extends in the first direction D1 from the support member 28. The second stacking member 42 extends in the first direction D1 from the first stacking member 41. The support member 28, the first stacking member 41, and the second stacking member 42 are arranged in this order in the first direction D1. The media 99 guided by the support member 28 are stacked on the stacking members. The stacking members support the media 99 received by the support member 28. The stacking members support the media 99 together with the support member 28, the first convex member 31, and the second convex member 32.

[0042] As shown in FIG. 2 and FIG. 5, the first stacking member 41 and the second stacking member 42 may be configured to be foldable. In one example, the second stacking member 42 is configured to be foldable so as to be located below the first stacking member 41. That is, the second stacking member 42 is configured to be stored below the first stacking member 41. The second stacking member 42 is connected to the first stacking member 41 so as to rotate. The second stacking member 42 is displaced from the state shown in FIG. 2 to the state shown in FIG. 5 by rotating relative to the first stacking member 41 about the connection point between the first stacking member 41 and the second stacking member 42 as an axis. In the folded state of the second stacking member 42, the first stacking member 41 and the second stacking member 42 are not aligned in the first direction D1. By folding the second stacking member 42, the foot space of the medium stacking device 21 is reduced.

[0043] As shown in FIG. 6, the loading member has a plurality of ribs. More specifically, the first loading member 41 has a plurality of first ribs 43. In one example, the first loading member 41 has five first ribs 43. The second loading member 42 has a plurality of second ribs 44. In one example, the second loading member 42 has five second ribs 44. The plurality of ribs are positioned at intervals in the second direction D2. The plurality of ribs support the medium 99. The loading member supports the medium 99 guided by the support member 28. Therefore, even if the loading member supports the medium 99 with a rod-shaped member such as a rib, the posture of the medium 99 is maintained stable.

[0044] The loading members have connecting members. More specifically, the first loading member 41 has a first connecting member 45. The second loading member 42 has a second connecting member 46. The connecting members extend in the second direction D2. The connecting members connect the multiple ribs. The first connecting member 45 connects the multiple first ribs 43. The first connecting member 45 connects the respective tips of the multiple first ribs 43. The second connecting member 46 connects the multiple second ribs 44. The second connecting member 46 connects the respective tips of the multiple second ribs 44. The second connecting member 46 may contact the floor surface. This stabilizes the posture of the second loading member 42.

[0045] The first rib 43 extends in the first direction D1. The first rib 43 is attached to the installation member 27 or the support member 28. In one example, a base end of the first rib 43 is attached to the installation member 27 or the support member 28. The first rib 43 may be attached to the installation member 27 or the support member 28 so as to rotate about its base end as an axis. The multiple first ribs 43 are, for example, arranged symmetrically in the second direction D2 with respect to the center of the first loading member 41. The multiple first ribs 43 are, for example, arranged at equal intervals.

[0046] The multiple first ribs 43 are arranged at intervals in the second direction D2. The multiple first ribs 43 support the medium 99. The medium 99 is supported by the multiple first ribs 43, so that the medium 99 is in a wavy state. This makes the medium 99 less likely to curl. The portion of the medium 99 supported by the multiple first ribs 43 is curved more finely than the portion supported by the support member 28.

[0047] The first rib 43 is located below the first convex member 31 and the second convex member 32. More specifically, the first rib 43 is located below the first convex surface 33 and the second convex surface 34. The first rib 43 extends to a position below the first convex member 31 and the second convex member 32. In other words, the first convex member 31 and the second convex member 32 are located such that the first convex surface 33 and the second convex surface 34 are located above the first rib 43. This makes it easier for the medium 99 to move from the support member 28 to the first rib 43.

[0048] 3 and 4, the multiple first ribs 43 include one or more first ribs 43 attached to the installation member 27 and one or more first ribs 43 attached to the support member 28. In one example, the first ribs 43 located second and fourth in the second direction D2 among the five first ribs 43 are attached to the installation member 27. The first ribs 43 located first, third and fifth in the second direction D2 among the five first ribs 43 are attached to the support member 28. The multiple first ribs 43 may be attached only to the installation member 27 or only to the support member 28.

[0049] The multiple first ribs 43 may include one or more first ribs 43 located at a first height and one or more first ribs 43 located at a second height different from the first height. In one example, the height at which the first rib 43 attached to the installation member 27 is located is different from the height at which the first rib 43 attached to the support member 28 is located. In detail, the first rib 43 attached to the installation member 27 is located lower than the first rib 43 attached to the support member 28. As a result, as shown by the two-dot chain line in Figures 3 and 4, the medium 99 is curved in a wavy manner by the multiple first ribs 43 when viewed from the first direction D1.

[0050] As shown in FIG. 6, the first loading member 41 supports a portion of the media 99 located in the first loading area A2 in the second direction D2. The first loading area A2 is an area occupied by the multiple first ribs 43 in the second direction D2. That is, the first loading area A2 is an 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 an area from the first rib 43 located at the first position to the fifth rib 43 located at the fifth position in the second direction D2 among the five first ribs 43. The smaller the length of the first loading area A2, the more the side edges of the media 99 hang down.

[0051] The first loading area A2 is smaller than the support area A1. Therefore, the side end of the medium 99 hangs down more on the first loading member 41 than on the support member 28. That is, the loading section 26 supports the medium 99 so that the side end hangs down more toward the first direction D1. This makes it easier for the medium 99 to form curved streaks L1 extending in the first direction D1, as shown by the two-dot chain line in FIG. 6. In detail, two curved streaks L1 are formed on the medium 99 by both side ends of the medium 99 hanging down. The two curved streaks L1 extend toward the first direction D1 so that the distance between the curved streaks L1 becomes smaller. By causing the side ends of the medium 99 to hang down more, the risk of the medium 99 curling due to a curling tendency is reduced.

[0052] The second rib 44 extends in the first direction D1. The second rib 44 is attached to the first loading member 41. More specifically, the second rib 44 is attached to the first connecting member 45. In one example, the base end of the second rib 44 is attached to the first connecting member 45. In one example, the second rib 44 is attached to the first connecting member 45 so as to rotate about its base end as an axis. The second rib 44 is supported by the first connecting member 45 so as to rotate relative to the first connecting member 45. This makes it possible for the second loading member 42 to be folded relative to the first loading member 41. The multiple second ribs 44 are, for example, arranged symmetrically in the second direction D2 with respect to the center of the second loading member 42 as a reference.

[0053] 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. This makes it easier for the medium 99 to advance from the first rib 43 to the second rib 44.

[0054] The plurality of second ribs 44 may include a plurality of second ribs 44 located at different heights, similar to the first rib 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 among the five second ribs 44 in the second direction D2 are located at higher positions than the second and fourth second ribs 44. The medium 99 is curved in a wavy manner by the plurality of second ribs 44.

[0055] The second ribs 44 are positioned 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. More specifically, the 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 second rib 44 located at the first position in the second direction D2 among the five second ribs 44 and the second rib 44 located at the second position is smaller than the interval between the first ribs 43. Also, the interval between the second rib 44 located at the fourth position in the second direction D2 among the five second ribs 44 and the second rib 44 located at the fifth position is smaller than the interval between the first ribs 43. As a result, the portion of the medium 99 supported by the second ribs 44 is curved more finely than the portion supported by the first ribs 43. As a result, the medium 99 is less likely to curl. The second ribs 44 may be arranged at equal intervals in the second direction D2.

[0056] The second loading member 42 supports a portion of the media 99 located in the second loading area A3 in the second direction D2. The second loading area A3 is an area occupied by the multiple second ribs 44 in the second direction D2. That is, the second loading area A3 is an 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 an area from the first second rib 44 to the fifth second rib 44 among the five second ribs 44 in the second direction D2.

[0057] The second loading area A3 is smaller than the first loading area A2. Therefore, the side end of the medium 99 hangs down more on the second loading member 42 than on the first loading member 41. That is, the loading section 26 supports the medium 99 so that the side end hangs down more toward the first direction D1. This makes it easier for curved streaks L1 to be formed on the medium 99, as shown by the two-dot chain line in FIG. 6. In the process in which the medium 99 advances on the loading section 26 in the first direction D1, the leading end of the medium 99 is likely to curl due to the curling tendency. This is because, in the process in which the medium 99 advances, the rear end of the medium 99 is held by the discharge section 20. In other words, while the rear end of the medium 99 is held by the discharge section 20, the leading end of the medium 99 is a free end. Therefore, in the process in which the medium 99 advances on the loading section 26 in the first direction D1, the leading end of the medium 99 is more likely to curl than the rear end of the medium 99. In contrast, by supporting the medium 99 so that the side edges of the medium 99 hang down more in the first direction D1, the risk of the medium 99 curling due to a curling tendency is reduced.

[0058] As shown in FIG. 2, the medium loading device 21 may include an auxiliary unit 51. The auxiliary unit 51 is configured to assist the loading unit 26. The auxiliary unit 51 is configured to support the loading member. The auxiliary unit 51 is attached to the leg 22. The auxiliary unit 51 is attached to the loading member. In one example, the auxiliary unit 51 is attached to the first loading member 41. The auxiliary unit 51 is attached to the first connecting member 45. Since the first loading member 41 and the second loading member 42 are long in the first direction D1, the load at the connection point is likely to be large. The auxiliary unit 51 supports the first connecting member 45, thereby reducing the load at the connection point. Therefore, the posture of the first loading member 41 and the second loading member 42 is stabilized.

[0059] The medium loading device 21 includes a stopper 52. The stopper 52 is attached to the loading section 26. For example, the stopper 52 is attached to a loading member. The stopper 52 is attached to the first loading member 41 or the second loading member 42. The stopper 52 is attached to a rib. That is, the stopper 52 is attached to the first rib 43 or the second rib 44. In one example, the stopper 52 is attached to the first rib 43. The stopper 52 may be attached to the support member 28.

[0060] Stopper 52 comes into contact with the leading edge of medium 99. As a result, stopper 52 receives medium 99. Stopper 52 stops medium 99 traveling in first direction D1 on stacker 26. This reduces the risk of medium 99 falling off stacker 26.

[0061] The stopper 52 may be attached to the loading section 26 so as to be displaced in the first direction D1. The stopper 52 may be attached so as to move along a rib. The stopper 52 may be configured to be detachable from the rib. This allows the stopper 52 to be displaced according to the length of the medium 99 to be discharged. For example, when the length of the medium 99 is large, the stopper 52 may be displaced in the first direction D1. The stopper 52 can come into contact with the leading end of the medium 99 at any position in the first direction D1. The stopper 52 can stop the medium 99 at any position in the first direction D1.

[0062] The stopper 52 has an attachment portion 53 attached to the rib. The attachment portion 53 sandwiches the rib. This allows the stopper 52 to be attached to the rib. The attachment portion 53 is configured to sandwich and release the rib. Therefore, the stopper 52 is configured to be detachable from the rib. This allows the stopper 52 to be displaced in the first direction D1.

[0063] The medium stacking device 21 includes a regulating unit 61. The regulating unit 61 is located above the stacking unit 26. The regulating unit 61 is configured to press down the medium 99 stacked on the stacking unit 26 from above. By pressing down the medium 99, the regulating unit 61 reduces the risk of the medium 99 curling.

[0064] The restricting portion 61 has one or more connecting members. In one example, the restricting portion 61 has a first connecting member 62 and a second connecting member 63. The connecting members extend in the second direction D2. The connecting members are connected to the first side frame 24 and the second side frame 25. The connecting members are installed across the first side frame 24 and the second side frame 25. The first connecting member 62 and the second connecting member 63 are arranged in this order in the first direction D1.

[0065] The restriction portion 61 has one or more restriction units. The restriction portion 61 has, for example, 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.

[0066] The regulating unit holds down media 99 loaded on the stacking member. The first regulating unit 64 holds down media 99 loaded on the first stacking member 41. The first regulating unit 64 is located above the first stacking member 41. The first regulating unit 64 is attached to the first connecting member 62 and the second connecting member 63. The second regulating unit 65 holds down media 99 loaded on the second stacking member 42. The second regulating unit 65 is located above the second stacking member 42. The second regulating unit 65 is attached to the second connecting member 63.

[0067] The three first regulating units 64 are arranged at intervals in the second direction D2. The three first regulating units 64 are arranged symmetrically in the second direction D2, for example, with respect to the center of the first stacking member 41. The three first regulating units 64 are arranged at equal intervals, for example.

[0068] The first regulating units 64 are positioned to face the first ribs 43. That is, when viewed from above, the first regulating units 64 overlap the first ribs 43. This allows the first regulating units 64 to hold down the portions of the media 99 that are lifted by the first ribs 43. As a result, the risk of the media 99 becoming clogged is reduced. In one example, the three first regulating units 64 face the first, third, and fifth first ribs 43 of the five first ribs 43 in the second direction D2, respectively.

[0069] 7 and 8, the first regulating unit 64 has a first mounting member 66 and one or more first regulating members 67. In one example, the first regulating unit 64 has the first mounting member 66 and a plurality of first regulating members 67.

[0070] The first mounting member 66 extends in the first direction D1. A base end of the first mounting member 66 is attached to the first connecting member 62. A tip end of the first mounting member 66 is attached to the second connecting member 63. The first mounting member 66 is positioned so as to face the first rib 43.

[0071] The first regulating member 67 is attached to the first mounting member 66. The first regulating member 67 is attached so as to approach the first stacking member 41 from the first mounting member 66. The first regulating member 67 is attached so as to protrude downward from the first mounting member 66.

[0072] The first regulating member 67 presses the medium 99 by contacting the medium 99. The first regulating member 67 has a regulating surface that contacts the medium 99 from above. That is, the first regulating member 67 has a first regulating surface 68. The first regulating surface 68 extends in the first direction D1. The first regulating member 67 is attached to the first mounting member 66 so that the first regulating surface 68 is parallel to the first rib 43.

[0073] The multiple first regulating members 67 are aligned in the first direction D1 on the first mounting member 66. The multiple first regulating members 67 are aligned in the first direction D1 such that their respective first regulating surfaces 68 are adjacent when viewed from the second direction D2. The multiple first regulating surfaces 68 are positioned so as to be continuous when viewed from the second direction D2. This reduces the risk of the medium 99 entering the gaps between the first regulating members 67. This reduces the risk of the medium 99 becoming clogged.

[0074] The first regulating member 67 may be attached to the first mounting member 66 so as to swing. In one example, the first regulating member 67 swings relative to the first mounting member 66 so that the first regulating surface 68 faces the first direction D1. The first regulating member 67 is a flap. The first regulating member 67 swings so that the first regulating surface 68 faces the first direction D1 by receiving a reaction force from the medium 99. This reduces the risk of the medium 99 becoming clogged due to the first regulating member 67 coming into strong contact with the medium 99. The multiple first regulating members 67 swing independently of each other, for example.

[0075] The first regulating unit 64 may have one or more rotating members. In one example, the first regulating unit 64 has a plurality of first rotating members 69. The first rotating members 69 are rollers. The first rotating members 69 are attached to the first regulating member 67. The first rotating members 69 rotate relative to the first regulating member 67. When viewed from the second direction D2, the first rotating members 69 are positioned so as to protrude from the first regulating surface 68 toward the first stacking member 41. The first rotating members 69 come into contact with the media 99 as the first regulating member 67 presses the media 99. The first rotating members 69 rotate by coming into contact with the media 99. The first rotating members 69 guide the media 99 in the first direction D1 by rotating. The first rotating members 69 reduce the risk of the media 99 becoming clogged.

[0076] As shown in FIG. 2, the second regulating unit 65 is positioned to face the second rib 44. That is, when viewed from above, the second regulating unit 65 overlaps with the second rib 44. This allows the second regulating unit 65 to hold down the portion of the medium 99 that is lifted by the second rib 44. As a result, the risk of the medium 99 getting stuck is reduced. In one example, the second regulating unit 65 faces the second rib 44 that is the fourth of the five second ribs 44 in the second direction D2. This is to reduce the risk of the medium 99 having a small width curling up. In the case of a medium 99 having a small width, the side end of the medium 99 may not hang down sufficiently. In more detail, the side end that is located on the second direction D2 side of the second rib 44 that is the fifth of the five second ribs 44 in the second direction D2 may not hang down sufficiently. In this case, the curved streak L1 is unlikely to be formed, so the medium 99 may lift up. In response to this, the second regulating unit 65 is disposed offset in the second direction D2 from the center of the second stacking member 42, thereby making it possible to hold down areas of the medium 99 that are prone to floating up. This reduces the risk of narrow media 99 curling.

[0077] The second regulating unit 65 has one or more second regulating members 70. In one example, the second regulating unit 65 has one second regulating member 70. The second regulating unit 65 may have a plurality of second regulating members 70, similar to the first regulating unit 64.

[0078] The second regulating member 70 extends in the first direction D1. The second regulating member 70 extends elongatedly along the second rib 44. The second regulating member 70 is attached to the second connecting member 63. More specifically, a base end of the second regulating member 70 is supported by the second connecting member 63. A tip end of the second regulating member 70 is supported by the second loading member 42. In one example, the tip end of the second regulating member 70 is supported by the second coupling member 46. This stabilizes the posture of the second regulating member 70.

[0079] The second regulating member 70 may be rotatably attached to the second connecting member 63. When the second loading member 42 is folded, the second regulating member 70 can retreat onto the first regulating unit 64 by rotating about a portion attached to the second connecting member 63 as an axis.

[0080] As shown in Figures 7 and 8, the second regulating member 70 is positioned to face the second rib 44. The second regulating member 70 contacts the medium 99, thereby holding down the medium 99 that is rising. The second regulating member 70 has a regulating surface that holds down the medium 99. In other words, the second regulating member 70 has a second regulating surface 71. The second regulating surface 71 extends in the first direction D1. The second regulating surface 71 is parallel to the second rib 44.

[0081] The second regulating unit 65 may have one or more rotating members. In one example, the second regulating unit 65 has a plurality of second rotating members 72. The second rotating members 72 are rollers. The second rotating members 72 are attached to the second regulating member 70. The second rotating members 72 rotate relative to the second regulating member 70. When viewed from the second direction D2, the second rotating members 72 are positioned so as to protrude from the second regulating surface 71 toward the second stacking member 42. The second rotating members 72 come into contact with the media 99 as the second regulating member 70 presses the media 99. The second rotating members 72 are rotatable by coming into contact with the media 99. The second rotating members 72 guide the media 99 in the first direction D1 by rotating. The second rotating members 72 reduce the risk of the media 99 becoming clogged.

[0082] <Action and Effects> Next, the operation and effects of the above embodiment will be described. (1) The first convex surface 33 and the second convex surface 34 are located above the support surface 29. The medium 99 may be prone to curling in the first direction D1 due to its curling tendency. With the above configuration, the first convex member 31 and the second convex member 32 support the medium 99 so as to lift it up relative to the support member 28. This causes the medium 99 to curve such that the curved streak L1 extends in the first direction D1. As a result, the risk of the medium 99 curling due to its curling tendency is reduced.

[0083] (2) The first stacking member 41 has a plurality of first ribs 43 extending in the first direction D1. According to the above configuration, the medium 99 is supported by the plurality of first ribs 43 and tends to undulate in the second direction D2. This reduces the risk of the medium 99 becoming curled due to a curling tendency.

[0084] (3) The first convex member 31 and the second convex member 32 are positioned such that the first convex surface 33 and the second convex surface 34 are positioned above the multiple first ribs 43. With the above configuration, the media 99 in the stacker 26 tend to advance in the first direction D1.

[0085] (4) The distance between the second ribs 44 is smaller than the distance between the first ribs 43. According to the above configuration, the medium 99 is supported by the multiple second ribs 44, and thus has a more finely wavy shape than the portion supported by the multiple first ribs 43. That is, the portion of the medium 99 supported by the multiple second ribs 44 has a more finely wavy shape than the portion supported by the multiple first ribs 43. This reduces the risk of the medium 99 curling due to a curling tendency.

[0086] (5) The second stacking member 42 is configured to be stored below the first stacking member 41 by rotating relative to the first stacking member 41 around the connection point between the first stacking member 41 and the second stacking member 42. According to the above configuration, the second stacking member 42 is stored below the first stacking member 41, thereby reducing the foot space of the medium stacking device 21. This improves the usability of the medium stacking device 21.

[0087] (6) The length of the second stacking area A3 is smaller than the length of the first stacking area A2. With the above configuration, the medium 99 is likely to bend such that the curved crease L1 extends from the first convex member 31 and the second convex member 32 to the second stacking member 42. This reduces the risk of the medium 99 curling due to a curling tendency.

[0088] (7) The medium loading device 21 is provided with a stopper 52 that is attached to the loading section 26 and contacts the leading edge of the medium 99. According to the above configuration, the stopper 52 contacts the leading edge of the medium 99, causing the medium 99 to stop on the loading section 26. Therefore, the risk of the medium 99 falling from the loading section 26 is reduced.

[0089] (8) Stopper 52 is attached to stacker 26 so as to be displaceable in first direction D1. With the above configuration, stopper 52 can be displaced in accordance with the length of media 99. This reduces the risk of media 99 falling off stacker 26.

[0090] (9) The multiple first regulating surfaces 68 are positioned so as to be continuous when viewed from the second direction D2. With the above configuration, the multiple first regulating surfaces 68 are positioned so as to be continuous in the first direction D1, so there is no risk of the medium 99 getting into the gaps between the first regulating members 67. This reduces the risk of the medium 99 becoming clogged.

[0091] (10) The multiple first regulating members 67 swing relative to the first mounting member 66 so that the first regulating surfaces 68 face the first direction D1. In the medium stacking device 21, media 99 with high rigidity may be stacked. In this case, the media 99 may come into strong contact with the first regulating members 67, which may cause damage to the media 99. With the above configuration, the first regulating members 67 are pushed up by the media 99, reducing the risk of the media 99 coming into strong contact with the first regulating members 67.

[0092] (11) The first direction D1 is a direction that extends obliquely downward. According to the above configuration, the stacking unit 26 extends obliquely downward. Therefore, the media 99 discharged from the processing device 11 tend to slide on the stacking unit 26 in the first direction D1 due to gravity. This makes it easier for the stacking unit 26 to stack the media 99.

[0093] <Example of change> The above embodiment can be modified as follows: The above embodiment and the following modified examples can be combined with each other to the extent that there is no technical contradiction.

[0094] The first restricting unit 64 may be configured such that the first restricting member 67 is directly attached to the connecting member, similar to the second restricting unit 65. For example, the first restricting member 67 may be configured not to swing, similar to the second restricting member 70.

[0095] The second regulating unit 65 may have an attachment member, similar to the first regulating unit 64. For example, the second regulating member 70 may be configured to swing, similar to the first regulating member 67.

[0096] <Technical philosophy> The technical ideas and effects obtained from the above-mentioned embodiment and modified examples will be described below.

[0097] (A) A medium loading device is a medium loading device on which media discharged from a processing device are loaded, and includes a loading section extending in a first direction on which the media are loaded, the loading section having a support member for supporting the media and a first convex member and a second convex member located on both sides of the support member in a second direction different from the first direction, the support member having a support surface for supporting the media, the first convex member having a first convex surface for supporting the media, the second convex member having a second convex surface for supporting the media, and the first convex surface and the second convex surface being located above the support surface. The media may be prone to curling in the first direction due to its curling tendency. According to the above configuration, the first convex member and the second convex member support the media so as to lift it up against the support member. This causes the media to curve so that streaks extend in the first direction. As a result, the risk of the media curling due to its curling tendency is reduced.

[0098] (B) In the medium loading device, the loading section may have a loading member extending from the support member in the first direction, the loading member having a plurality of ribs extending in the first direction, and the plurality of ribs may be spaced apart in the second direction. With the above configuration, the medium is supported by the plurality of ribs, and thus tends to become wavy in the second direction. This reduces the risk of the medium becoming curled due to a curling tendency.

[0099] (C) In the medium loading device, the first convex member and the second convex member may be positioned such that the first convex surface and the second convex surface are positioned above the plurality of ribs. With the above configuration, the medium is easily advanced in the first direction in the loading section.

[0100] (D) In ​​the above medium loading device, the loading member may be a first loading member, the plurality of ribs may be a plurality of first ribs, the loading section may have a second loading member extending from the first loading member in the first direction, the second loading member may have a plurality of second ribs extending in the first direction, the plurality of second ribs may be spaced apart in the second direction, and the distance between the second ribs may be smaller than the distance between the first ribs. According to the above configuration, the medium is supported by the plurality of second ribs, and thus the medium is in a state of finer undulations compared to the portion supported by the plurality of first ribs. That is, the portion of the medium supported by the plurality of second ribs is in a state of finer undulations compared to the portion supported by the plurality of first ribs. This reduces the risk of the medium curling due to a curling tendency.

[0101] (E) In the above medium loading device, the second stacking member may be connected to the first stacking member so as to rotate relative to the first stacking member, and may be configured to be stored below the first stacking member by rotating relative to the first stacking member. According to the above configuration, the second stacking member is stored below the first stacking member, thereby reducing the foot space of the medium loading device. This improves the usability of the medium loading device.

[0102] (F) In the medium loading device, the width of an area occupied by the second ribs in the second direction may be smaller than the width of an area occupied by the first ribs in the second direction. With the above configuration, the medium is likely to bend so that a streak extends from the first convex member and the second convex member to the second loading member. This reduces the risk of the medium curling due to a curling tendency.

[0103] (G) The medium loading device may include a stopper attached to the loading section and adapted to contact the leading edge of the medium. According to the above configuration, the stopper contacts the leading edge of the medium, thereby stopping the medium on the loading section. This reduces the risk of the medium falling off the loading section.

[0104] (H) In the medium loading device, the stopper may be attached to the loading section so as to be displaced in the first direction. With the above configuration, the stopper can be displaced according to the length of the medium. This reduces the risk of the medium falling off the loading section.

[0105] (I) The medium loading device includes a regulating section located above the loading section, the regulating section having a plurality of regulating members arranged in the first direction, the plurality of regulating members each having a regulating surface that contacts the medium from above, and the plurality of regulating surfaces may be positioned so as to be continuous when viewed from the second direction. According to the above configuration, since the plurality of regulating surfaces are positioned so as to be continuous in the first direction, there is no risk of the medium getting into the gaps between the regulating members. Therefore, the risk of the medium getting stuck is reduced.

[0106] (J) In the above medium loading device, the regulating section may have a mounting member to which the multiple regulating members are attached so that they each swing, and the multiple regulating members may swing relative to the mounting member so that the regulating surfaces face the first direction. In the medium loading device, media with high rigidity may be loaded. In this case, the media may be damaged due to the high rigidity media coming into strong contact with the regulating member. According to the above configuration, the media is pushed up against the regulating member, thereby reducing the risk of the media coming into strong contact with the regulating member.

[0107] (K) In the medium loading device, the first direction may be a direction extending diagonally downward. According to the above configuration, the loading section extends diagonally downward. Therefore, the medium discharged from the processing device is more likely to slide in the first direction on the loading section due to gravity. This makes it easier for the loading section to load the medium. [Explanation of symbols]
