The placement section is provided on a device main body and places a single sheet discharged from a discharge section. The correction section is disposed downstream of the placement section in a discharge direction and corrects curling of the single sheet by contacting the single sheet moving in the discharge direction from the placement section. Further, the correction section has a contact surface that extends in a cross direction intersecting the discharge direction in a manner that the position in the up-down direction becomes lower from upstream to downstream of the discharge direction and contacts the single sheet.

Description

Technical Field

[0001] This invention relates to a media loading device and a recording system. Background Technology

[0002] The recording medium receiving device described in Patent Document 1 receives relatively large-sized printed paper that is ejected after recording via a thin plate component.

[0003] In a device like the one described in Patent Document 1, where a large-sized medium with a relatively long length in the discharge direction is discharged into the mounting section, a portion of the medium may be exposed downstream from the downstream end in the discharge direction of the mounting section.

[0004] Here, although the downstream portion of a large-sized medium discharged into the mounting section may curl into a cylindrical shape at its width end in the direction away from the mounting section (i.e., upwards), as this downstream portion passes the mounting section while still curled into a cylindrical shape, its own weight will cause it to descend, resulting in the curled portion folding. In this case, the downstream end of the medium to be discharged next may get caught on the folded portion of the already discharged medium, resulting in poor stacking.

[0018] Hereinafter, the first to thirteenth embodiments of the present invention will be described in summary.

[0019] The media loading apparatus according to the first aspect of the present invention for solving the above-mentioned problems is characterized in that it is a media loading apparatus for loading media discharged from the discharge section of a processing device, the media loading apparatus comprising: a mounting section disposed on a device body and mounting at least one sheet of the media discharged from the discharge section; and a straightening section disposed downstream of the mounting section in the movement direction of the media in the mounting section, which straightens the curling of the media by contacting the media moving from the mounting section in the movement direction, the straightening section having at least one contact surface extending in an intersecting direction relative to the movement direction and contacting the media, wherein the position in the device height direction decreases from upstream to downstream in the movement direction.

[0020] According to this method, when a portion of the medium moving in the mounting section becomes curled upwards in the device height direction and is exposed downstream compared to the mounting section, this portion of the medium comes into contact with the contact surface of the straightening section. Here, since the contact surface extends in the intersecting direction with its position decreasing from upstream to downstream in the movement direction in the device height direction, the portion of the medium in contact with the contact surface is straightened in the direction opposite to the upward curling direction. Therefore, when the portion of the medium exposed from the mounting section droops due to its own weight, the folding of the medium is suppressed, thus preventing poor stacking of the next medium onto the previous medium when the next medium is placed on the mounting section.

[0021] Furthermore, according to this method, since poor stacking of the medium can be suppressed even if the length of the moving direction of the mounting portion is shorter than the length of the moving direction of the medium, the mounting portion can be miniaturized.

[0022] The medium loading device involved in the second method is characterized in that, in the first method, the main body of the device has an opposing part, the opposing part is positioned above the loading part in the height direction of the device, and the correction part is disposed on the opposing part.

[0023] According to this method, since the corrective part is supported by the opposing part provided on the main body of the device, there is no need to prepare a separate component to support the corrective part.

[0024] The media loading device involved in the third method is characterized in that, in the second method, the position of the downstream end of the opposing part in the moving direction is aligned with the position of the downstream end of the loading part in the moving direction, and the correction part is provided at the downstream end of the opposing part in the moving direction.

[0025] According to this method, in the direction of movement, the downstream end of the mounting portion is aligned with the downstream end of the opposing portion. Therefore, a portion of the medium exposed from the mounting portion contacts the correcting portion without contacting the opposing portion. Thus, curling can be corrected from an earlier stage at the portion of the medium exposed from the mounting portion.

[0026] The media loading device according to the fourth method is characterized in that, in any one of the first to third methods, in the height direction of the device, the height position of the downstream end of the moving direction of the correcting part is aligned with the height position of the downstream end of the moving direction of the loading part.

[0027] According to this method, the height of the downstream end of the correcting part is aligned with the height of the downstream end of the mounting part. Therefore, when a rigid medium that is less prone to curling is discharged and moves almost straight downstream from the mounting part, the medium can easily pass over the correcting part even if it comes into contact with it. In other words, when using a rigid medium, it is possible to prevent the medium from getting stuck on the correcting part.

[0028] The media loading device according to the fifth method is characterized in that, in any one of the first to third methods, in the height direction of the device, the height position of the downstream end of the moving direction of the correcting part is located lower than the height position of the downstream end of the moving direction of the loading part.

[0029] According to this method, since the height position of the downstream end of the correction part is located lower than the height position of the downstream end of the mounting part, it is possible to suppress the situation where a portion of the medium with relatively low rigidity travels in the moving direction through the lower end of the correction part.

[0030] The medium loading device according to the sixth method is characterized in that, in any one of the first to fifth methods, the correction unit is provided in a manner that allows it to be displaced to a correction position when the medium is being corrected and to a retracted position when it leaves the correction position relative to the loading unit.

[0031] According to this method, when using a medium that is difficult to curl and has high rigidity, since the correcting part is displaced to the retracted position so that the correcting part is no longer located in the moving direction of the medium, it is possible to suppress the medium from getting stuck on the correcting part.

[0032] The medium loading device involved in the seventh method is characterized in that, in the sixth method, a pressing member is provided, which presses the correcting part downward in the height direction of the device.

[0033] When the medium with high rigidity comes into contact with the correcting part, the correcting part may experience a positional shift in the direction of movement due to the strong compressive force exerted by the medium.

[0034] Here, according to this method, since the corrective force is countered not only by the reaction force of the corrective part but also by the pressing force of the pressing member to resist the squeezing force from the medium, the positional displacement of the corrective part can be suppressed.

[0035] The media loading device according to the eighth method is characterized in that, in the sixth or seventh method, it has a driving unit and a control unit, wherein the driving unit drives the correction unit to one of the correction position and the retraction position, and the control unit controls the driving of the driving unit according to the medium.

[0036] According to this method, since the control unit controls the drive of the drive unit according to the medium to switch the position of the correction unit, the correction unit is no longer configured at the retracted position when using the medium with relatively low rigidity.

[0037] The media loading apparatus according to the ninth method is characterized in that, in the eighth method, when the medium is a thin paper having a thickness that is thinner than a set thickness, and when recording is performed on the medium using a liquid at a density that is higher than a set density, the control unit positions the correction unit in the correction position.

[0038] According to this method, even if the paper is swollen by the liquid, resulting in a larger curl in the paper, the curl of the paper can still be corrected because the correcting part is located in the correcting position.

[0039] The medium loading device according to the tenth method is characterized in that, in any one of the first to ninth methods, the correction part has a plurality of contact surfaces that are spaced apart in the medium width direction which intersects both the moving direction and the device height direction, and that contact both ends of the medium in the medium width direction.

[0040] According to this method, when using media with different sizes in the media width direction, since the two ends of the media in the media width direction, which are prone to curling, contact the contact surface regardless of the size in the media width direction, it is possible to suppress the situation where curling is not corrected when the size of the media is changed.

[0041] The medium loading device according to the eleventh method is characterized in that, in any one of the first to tenth methods, when viewed from the medium width direction which intersects both the movement direction and the device height direction, the contact surface extends in a straight line.

[0042] According to this method, since the trajectory drawn at the top of the moving direction of the medium is not curved but becomes a straight line, that is, a trajectory of the shortest distance, it is possible to suppress the situation where the moving path of the medium becomes longer compared with the structure where the contact surface is curved when viewed from the width direction of the medium.

[0043] The medium loading device according to the twelfth method is characterized in that, in any one of the first to eleventh methods, at a portion of the loading part upstream of the downstream end in the moving direction, an inclined surface is formed where the position in the height direction of the device increases from upstream to downstream in the moving direction.

[0044] According to this method, the medium discharged from the discharge section temporarily moves obliquely upward along the inclined surface. As a result, a portion of the medium's direction of movement becomes a mountain-shaped configuration. Compared to a structure where the medium is linear in the direction of movement, this configuration is more stable relative to the force acting in the direction of movement, thus preventing the medium from falling from the mounting section.

[0045] The recording system according to the thirteenth method is characterized in that it is a recording system comprising a recording device and a media loading device. In this recording system, the recording device comprises: a receiving section for receiving rolls of paper; a conveying section for conveying the rolls of paper from the receiving section; a recording section for recording on the rolls of paper conveyed by the conveying section; a cutting section for cutting the rolls of paper recorded by the recording section to form single sheets of paper as media; and a discharge section for discharging the single sheets of paper. The media loading device comprises: a carrier... The device includes a section that holds at least one sheet of paper discharged from the discharge section; and a straightening section that is disposed downstream of the section in the direction of movement of the sheet of paper, and corrects the curling of the sheet of paper by contacting it as it moves from the section in the direction of movement. The straightening section has at least one contact surface that extends in a cross direction relative to the direction of movement and contacts the sheet of paper, with its position in the height direction of the device decreasing from upstream to downstream in the direction of movement.

[0046] This method achieves the same effect as the first method.

[0047] Hereinafter, an example of the recording system and media loading device of the present invention will be specifically described.

[0048] In the various figures, the X direction along the X-axis is an example of the device width direction and medium width direction of the loading devices 30, 90, 100, and 110 described later. When the front surface of the device faces the user, the -X direction becomes the left direction and the +X direction becomes the right direction when viewed from the user's perspective.

[0049] The Y-direction along the Y-axis is an example of the longitudinal direction of the loading devices 30, 90, 100, and 110. The +Y-direction is an example of the direction from the back of the device toward the front surface, and is the direction of movement of the single sheet of paper PS in the mounting section 42, as described later. The -Y-direction is the direction from the front surface of the device toward the back. The X and Y directions are horizontal directions.

[0050] Along the Z-axis, the Z-direction is the height direction of the loading devices 30, 90, 100, and 110, and it is a vertical direction. The +Z direction is vertically upward, and the -Z direction is vertically downward. The X, Y, and Z directions are orthogonal to each other.

[0051] Paper P is an example of a medium and a recording medium. In the following description, for paper P, paper in roll form will be designated as roll paper PR, and paper cut into thin sheets will be designated as sheet paper PS, thus making a distinction.

[0052] Implementation Method 1

[0053] like Figure 1 As shown, the recording system 1 of Embodiment 1 includes a printer 10 as an example of a processing device and a recording device, and a loading device 30 as an example of a media loading device.

[0054] The printer 10 has a rectangular box 12. Furthermore, as an example, the printer 10 is configured as an inkjet printer capable of printing on paper P ranging in size from A4 to A0.

[0055] Furthermore, as a classification item for paper P, not only can its dimensions be listed, but also its bending stiffness relative to external forces acting on the out-of-plane direction of the paper P. Photo paper has relatively high bending stiffness. Plain paper has relatively low bending stiffness compared to photo paper. In printer 10, both plain paper and photo paper can be used for recording.

[0056] Specifically, the printer 10 includes a storage section 14, a conveying section 16, a recording section 18, a cutting section 22, and an ejection section 24 inside the housing 12. Furthermore, the printer 10 includes a control section 26 that controls the operation of each part of the printer 10. As an example, the control section 26 also functions as the control section of the loading device 30, which will be described later.

[0057] The housing 12 has a sidewall 13 forming a wall portion in the +Y direction. An outlet 19 extending through in the Y direction is formed on the sidewall 13. The outlet 19 is sized to allow all types of paper P usable in the printer 10 to pass through.

[0058] The storage section 14 stores the roll of paper PR that rotates around the central axis along the X direction.

[0059] The conveying section 16 has a plurality of conveying rollers 17. Furthermore, the conveying section 16 conveys the roll of paper PR pulled out from the receiving section 14 downstream along the conveying path K1 indicated by the double-dotted line.

[0060] The recording unit 18 uses ink Q, an example of a liquid, to record on the roll of paper PR being conveyed by the conveying unit 16. Furthermore, the roll of paper PR is conveyed in the +Y direction in the area opposite to the recording unit 18. Additionally, the recording unit 18 is located in the +Z direction relative to the roll of paper PR. In other words, recording is performed on the upper surface of the roll of paper PR in the +Z direction.

[0061] The cutting section 22 cuts the roll of paper PR that has been recorded by the recording section 18, thereby forming a single sheet of paper PS as a medium.

[0062] The discharge section 24 has a support platform 25 and a discharge roller pair 28 disposed downstream of the cutting section 22. The support platform 25 supports the sheet paper PS and guides it toward the discharge outlet 19. The discharge roller pair 28 feeds the sheet paper PS into the discharge outlet 19 via the support platform 25, thereby discharging the sheet paper PS outward from the discharge outlet 19. The sheet paper PS discharged from the discharge outlet 19 is conveyed to the loading device 30 along the conveying path K2, indicated by the double-dotted line. In addition, a path structure component (not shown) is disposed on the conveying path K2.

[0063] Next, the loading device 30 will be described.

[0064] The loading device 30 is loaded with single sheets of paper PS that are discharged from the discharge section 24. In addition, the loading device 30 includes a device body 31 and a straightening section 82 for straightening the single sheets of paper PS.

[0065] As an example, the main body 31 of the device includes a base 32, a mounting part 42 disposed on the base 32 and on which a single sheet of paper PS is mounted, an opposing part 66 opposite to the mounting part 42 in the Z direction, and a pressing part 72 for pressing the single sheet of paper PS.

[0066] The opposing portion 66 is positioned above the mounting portion 42 in the Z direction, which is above the mounting portion 42 in the +Z direction. Furthermore, as an example, five opposing portions 66 are provided at intervals in the X direction.

[0067] As an example, five correction sections 82 are provided at intervals in the X direction. Furthermore, the correction sections 82 are provided at the downstream end 66A in the +Y direction of the opposing section 66.

[0068] The base 32 is configured to include a leg frame 34 that stands upright in the Z direction, small casters 35 that are rotatably provided at the -Z end of the leg frame 34, and a support frame 36 provided at the +Z end of the leg frame 34. Furthermore, the base 32 supports the mounting portion 42, the opposing portion 66, the pressing portion 72, and the straightening portion 82 from the -Z direction. In this way, the loading device 30 can move in both the +Y and -Y directions.

[0069] The support frame 36 has a lower frame 38 supported on the leg frame 34, wall portions 39 extending vertically from both ends of the lower frame 38 in the X direction toward the +Z direction, and an upper frame 41 connected to the +Z ends of the wall portions 39 in the X direction. Furthermore, a cylindrical support shaft 51 extending along the X direction is provided on the upper frame 41.

[0070] The mounting section 42 holds at least one sheet of paper PS discharged from the discharge section 24. As an example, the moving direction of the sheet of paper PS on the mounting section 42 is set to the +Y direction. As an example, the mounting section 42 is composed of a first mounting section 43, a second mounting section 44, and a third mounting section 45 arranged from upstream to downstream in the +Y direction.

[0071] The first mounting portion 43 and the second mounting portion 44 are directly supported on the base 32. The third mounting portion 45 extends downstream from the +Y direction end of the second mounting portion 44 and is indirectly supported on the base 32 via the second mounting portion 44.

[0072] like Figure 2 As shown, as an example, the third mounting portion 45 has six main body portions 46 arranged at intervals in the X direction, and five connecting portions 56 connecting the six main body portions 46 in the X direction.

[0073] like Figure 3 As shown, as an example, the main body 46 is configured to include a plurality of longitudinal plates 48 spaced apart in the X direction and a front plate 54 connecting the plurality of longitudinal plates 48 in the X direction. The longitudinal plates 48 have a predetermined thickness in the X direction and are configured along the YZ plane. Furthermore, the longitudinal plates 48 extend in the +Y direction. As an example, the upper surface 49 of the longitudinal plates 48 in the +Z direction is included in the mounting surface 62 described later and is configured in the same manner as the mounting surface 62.

[0074] The front plate 54 has a specified thickness in the +Y direction and is configured along the XZ plane. Furthermore, the front plate 54 is formed into a rectangular shape in which the dimension in the X direction is larger than the dimension in the Z direction when viewed from the +Y direction.

[0075] As an example, the connecting part 56 is configured to include a plurality of longitudinal plates 58 spaced apart in the X direction and a base plate 59 connecting the plurality of longitudinal plates 58 in the X direction.

[0076] The longitudinal plates 58 have a specified thickness in the X direction and are arranged along the YZ plane. The X-direction spacing of the plurality of longitudinal plates 58 is wider than the X-direction spacing of the plurality of longitudinal plates 48. Furthermore, the longitudinal plates 58 extend in the +Y direction.

[0077] In addition, the width of the main body 46 in the X direction and the width of the connecting part 56 in the X direction are of the same size.

[0078] like Figure 5 As shown, a mounting surface 62 is formed at the end of the longitudinal plate 58 in the +Z direction. As an example, the mounting surface 62 has an inclined surface 63 and a flat surface 64.

[0079] The inclined surface 63 is formed at a position upstream of the downstream end 42A in the +Y direction of the mounting portion 42. Furthermore, the inclined surface 63 is located upstream of the flat surface 64. Specifically, the inclined surface 63 is a surface whose position in the +Z direction increases from upstream to downstream in the +Y direction. In other words, the inclined surface 63 is a surface that extends obliquely upward in such a way that the height position of the Z direction end at the +Y direction end is higher than the height position of the Z direction end at the -Y direction end.

[0080] Flat surface 64 is a surface along the XY plane.

[0081] When viewed from the X direction, the intersection of the line representing the inclined plane 63 and the line representing the flat plane 64 is designated as point A. The endpoint of the flat plane 64 in the +Y direction is designated as point B. The straight line extending segment AB in the +Y direction is designated as the horizontal reference line M. The straight line passing through point B and along the Z direction is designated as the vertical reference line N.

[0082] Five opposing parts 66 are supported on the upper frame 41. Figure 1 It extends from the upper frame 41 in the +Y direction. Furthermore, five opposing portions 66 are arranged in the +Z direction relative to the mounting portion 42. Although the portions of the five opposing portions 66 closer to the center in the Y direction are opposite to the connecting portion 56 in the Z direction, they are not opposite to the main body portion 46. Figure 3 Opposite.

[0083] The five opposing portions 66 are arranged symmetrically with respect to the center in the X direction. Furthermore, one of the five opposing portions 66 in the +X direction and one in the -X direction are arranged at positions that can oppose the two ends of the single sheet PS in the X direction.

[0084] As an example, the second frame 68B, described later, and the correction part 82, described later, are set as one unit. Therefore, the opposing part 66 refers to the portion in the -Y direction relative to the longitudinal reference line N when viewed from the X direction.

[0085] The position of the downstream end 66A of the opposing part 66 in the +Y direction is aligned with the position of the downstream end 42A of the mounting part 42 in the +Y direction.

[0086] like Figure 2 As shown, the five opposing portions 66 are connected by a connecting rod 73 extending in the X direction. At both ends of the connecting rod 73 in the X direction, there are gripping portions 75 for the user to grasp. The gripping portions 75 allow for manual rotation of the rotating portions 68 (described later) in the opposing portions 66. Figure 4 It is used when rotating.

[0087] like Figure 4As shown, when viewed from the X direction, the opposing part 66 has a fixed part 67 and a rotating part 68.

[0088] The fixing part 67 is fixed to the upper frame 41 using screws (not shown).

[0089] The rotating part 68 is positioned downstream of the fixed part 67 in the +Y direction. The end of the rotating part 68 in the -Y direction is connected to the support shaft 51 of the upper frame 41. Thus, the rotating part 68 is configured to rotate around the support shaft 51. The rotating part 68, which rotates towards the upper frame 41, is housed within the upper frame 41. When the length of the single sheet of paper PS is short, housing the rotating part 68 within the upper frame 41 facilitates the removal of the single sheet of paper PS from the mounting part 42.

[0090] In the retracted state of the rotating part 68, a portion of the rotating part 68 is restricted from rotation by engaging with a locking part (not shown). Thus, the rotating part 68 is held in an orientation along the Y direction.

[0091] like Figure 5 As shown, as an example, the lower surface 69 of the opposing portion 66 in the -Z direction is set to be a plane along the XY plane. The size of the space 71 between the lower surface 69 in the Z direction and the mounting surface 62 is set to allow single sheets of paper PS of various sizes to move in the +Y direction. Furthermore, the size of the space 71 is preset so that the curled single sheet of paper PS does not come into contact with the lower surface 69. That is, the lower surface 69 does not correct the curling of the single sheet of paper PS.

[0092] Additionally, as an example, the rotating part 68 has a first frame 68A that is rotatably connected to the support shaft 51, and a second frame 68B that is rotatably connected to the first frame 68A via the rotating shaft 61.

[0093] The pressing part 72 is composed of a plurality of pressing members 74 that are spaced apart in the Y direction in the opposing part 66. Furthermore, in Figure 5 The pressing component 74, located at the downstream end in the +Y direction, is shown in the image.

[0094] The pressing member 74 extends obliquely downward from the opposing portion 66 in the +Y direction, with its downstream end positioned closer to the -Z direction than its upstream end. One end of the pressing member 74 in its extending direction is rotatably connected to the opposing portion 66. A roller (not shown) is rotatably supported at the top end of the other end of the pressing member 74 in its extending direction. The outer peripheral surface of this roller can contact the upper surface of the sheet of paper PS loaded, which is closest to the +Z direction.

[0095] Point C is designated as the lower end of the pressing component 74 when viewed from the X direction. Point C is located upstream of point A in the +Y direction.

[0096] The pressing member 74 oscillates to change its height position in the Z direction when the loading amount of the sheet paper PS changes. However, the pressing member 74 is not a component that corrects curling at both ends of the sheet paper PS in the X direction.

[0097] The straightening section 82 is positioned downstream of the mounting section 42 in the +Y direction of the single sheet PS. Furthermore, the straightening sections 82 are arranged one by one on their respective opposing sections 66 at intervals in the X direction.

[0098] Specifically, the correction part 82 is provided at the downstream end 66A in the +Y direction of the opposing part 66. In other words, the correction part 82 is provided on the rotating part 68.

[0099] The corrective section 82 extends obliquely downward from the downstream end 66A, and its height decreases towards the downstream Z direction in the +Y direction. Furthermore, the corrective section 82 is positioned downstream of the longitudinal reference line N in the +Y direction. The corrective section 82 corrects the curling of the single sheet of paper PS by contacting a portion of the single sheet moving from the mounting section 42 in the +Y direction.

[0100] like Figure 3 As shown, as an example, the straightening section 82 consists of four straightening plates 84 spaced apart in the X direction, and an upper plate 85 covering the four straightening plates 84 from the +Z direction and connecting them in the X direction. Each of the four straightening plates 84 has a contact surface 86 that contacts the single sheet of paper (PS). Figure 5 In other words, the correction section 82 has four contact surfaces 86. These four contact surfaces 86 are spaced apart in the X direction, which is orthogonal to both the +Y and Z directions, and contact both ends of the single sheet PS in the X direction. Furthermore, in the following description, only one contact surface 86 will be described, and the description of the other three contact surfaces 86 will be omitted.

[0101] like Figure 5 As shown, the contact surface 86 extends in an intersecting direction relative to the +Y direction, with its position decreasing from upstream to downstream in the Z direction. Furthermore, the contact surface 86 extends in a straight line when viewed from the X direction. That is, the four contact surfaces 86 are inclined surfaces.

[0102] Point D is designated as the upstream endpoint in the +Y direction on the contact surface 86 when viewed from the X direction. Point D is located on the longitudinal reference line N. Furthermore, point E is designated as the downstream endpoint in the +Y direction on the contact surface 86. Point E is the point at the lower end of the straightening plate 84 in the Z direction. The contact surface 86 is represented by the line segment DE.

[0103] Points B and E are located on the horizontal reference line M. That is, the height of the flat surface 64 and the height of the downstream end of the contact surface 86 are aligned at the same height. In other words, in the Z direction, the height position of a portion of the downstream end 82A of the straightening part 82 in the +Y direction is aligned with the height position of the downstream end 42A of the mounting part 42 in the +Y direction.

[0104] The angle BED is set as the tilt angle θ of the correction section 82. As an example, the tilt angle θ is 20°. Although the tilt angle θ can be set within a range that corrects the curling of the single sheet of paper PS, it is preferable to select the tilt angle θ within the range of 15° to 40° in order to allow the relatively rigid paper P to move and to suppress the enlargement of the loading device 30 in the Y direction. Additionally, as an example, the length of the line segment BE is 100 mm.

[0105] Next, the operation of the recording system 1 and the loading device 30 in Embodiment 1 will be explained. Furthermore, for each structure of the recording system 1 and the loading device 30, reference will be provided. Figures 1 to 5 The description of individual figure numbers is omitted.

[0106] like Figure 6 As shown, in the loading device 30, as an example, the movement of a single sheet of thin paper PS, on the mounting section 42, where high-density recording has been performed, will be described. Furthermore, the size of the single sheet PS is the dimension by which the single sheet PS protrudes from the mounting surface 62 in the +Y direction. That is, when the single sheet PS is mounted on the mounting surface 62, the downstream portion of the single sheet PS in the +Y direction protrudes in the +Y direction compared to the mounting surface 62.

[0107] Here, the single sheet of paper (PS) becomes the ink Q (for recording) Figure 1 The paper is in a state of expansion due to saturation. Therefore, the two ends of the single sheet PS in the X direction are in an upward-curved state relative to the center in the +Z direction. Furthermore, the single sheet PS with its upward-curved ends in the X direction moves in the +Y direction as is, thereby contacting the contact surface 86 of the correction section 82.

[0108] exist Figure 7The diagram shows, as a schematic representation, the state of a portion of the mounting section 42 and a portion of the straightening section 82 as viewed from the +Y direction. Furthermore, to clarify the state of the single sheet PS, the single sheet PS is shown in perspective. A PS with double-dotted lines indicates a single sheet PS in a curled state with both ends pointing upwards in the X direction. A PS with solid lines indicates a single sheet PS whose curl has been corrected by the straightening section 82.

[0109] The portion of the single sheet PS extending from the mounting portion 42 in the +Y direction contacts the contact surface 86. Here, since both ends of the single sheet PS in the X direction are in contact with the contact surface 86, the upward curvature of the ends of the single sheet PS is corrected in a manner that is nearly flat along the X direction. In other words, the double-dotted PS is shaped into a solid-line PS. Therefore, even when the ends of the single sheet PS droop due to their own weight, the possibility of creases forming at these ends due to pocketing is suppressed.

[0110] When multiple sheets of paper (PS) are loaded onto the mounting section 42, the sheet of paper loaded onto the sheet of paper already mounted on the mounting surface 62 is discharged onto the corrected sheet of paper. Therefore, the situation where the ends of the next sheet of paper to be loaded become stuck on the already mounted sheet of paper is prevented. In other words, poor stacking of the sheet of paper in the loading device 30 is prevented.

[0111] As explained above, according to the loading device 30, when a portion of the single sheet PS moving on the mounting section 42 is curled upwards in the Z direction and exposed downstream compared to the mounting section 42, the portion of the single sheet PS contacts the contact surface 86 of the straightening section 82. Here, since the contact surface 86 extends in the intersecting direction with a position in the Z direction that decreases from upstream to downstream in the +Y direction, the portion of the single sheet PS in contact with the contact surface 86 is straightened in the opposite direction to the upward curling direction. As a result, since the situation where the portion of the single sheet PS exposed from the mounting section 42 is folded due to its own weight is suppressed, when the next single sheet PS is mounted on the mounting section 42, stacking defects such as jamming between the next single sheet PS and the previous single sheet PS can be suppressed.

[0112] Furthermore, according to the loading device 30, since even if the length of the mounting section 42 in the +Y direction is shorter than the length of the single sheet PS in the +Y direction, poor stacking of the single sheet PS can be suppressed, the mounting section 42 can be miniaturized.

[0113] According to the loading device 30, since the straightening part 82 is supported by the opposing part 66 provided on the main body 31 of the device, there is no need to prepare a separate component to support the straightening part 82.

[0114] According to the loading device 30, in the +Y direction, the downstream end 42A of the mounting section 42 and the downstream end 66A of the opposing section 66 are aligned. Therefore, a portion of the single sheet of paper PS exposed from the mounting section 42 contacts the straightening section 82 without contacting the opposing section 66. Thus, curling can be corrected from an earlier stage at the portion of the single sheet of paper PS exposed from the mounting section 42.

[0115] According to the loading device 30, the height position of the downstream end 82A of the straightening section 82 is aligned with the height position of the downstream end 42A of the mounting section 42. Therefore, when a single sheet of paper PS with high rigidity that is not prone to curling is discharged, and the single sheet of paper PS moves almost straight downstream from the mounting section 42, even if the single sheet of paper PS comes into contact with the straightening section 82, the single sheet of paper PS can easily pass over the straightening section 82. In other words, when using a single sheet of paper PS with high rigidity, it is possible to prevent the single sheet of paper PS from getting stuck on the straightening section 82.

[0116] According to the loading device 30, when using single sheet paper PS that is relatively difficult to curl and has high rigidity, since the straightening part 82 is moved to the retracted position so that the straightening part 82 is no longer located in the +Y direction of the single sheet paper PS, it is possible to suppress the situation where the single sheet paper PS with high rigidity gets stuck on the straightening part 82.

[0117] According to the loading device 30, when using single sheets of paper PS with different sizes in the X direction, since the two ends of the single sheets of paper PS that are prone to curling in the X direction are not related to the size of the single sheets of paper PS in the X direction but will contact the contact surface 86, it is possible to suppress the situation where curling is not corrected when the size of the single sheets of paper PS is changed.

[0118] According to the loading device 30, since the trajectory drawn by the top of the single sheet PS in the +Y direction is not curved but straight, that is, the trajectory of the shortest distance, it can suppress the situation where the moving path of the single sheet PS becomes longer compared with the structure of the contact surface 86 which is curved when viewed from the X direction.

[0119] According to the loading device 30, the single sheet of paper PS discharged from the discharge section 24 temporarily moves obliquely upward along the inclined plane 63. As a result, a portion of the single sheet of paper PS in the +Y direction becomes a mountain-shaped configuration. Compared with a structure in which the single sheet of paper PS is straight in the +Y direction, the configuration of the single sheet of paper PS is more stable relative to the force acting in the +Y direction, thus preventing the single sheet of paper PS from falling off the mounting section 42.

[0120] According to the printer 10, the same effect as the loading device 30 can be obtained.

[0121] Next, the loading device 70, a variation of the loading device 30, will be described. Furthermore, parts common to all parts of the loading device 30 of Embodiment 1 will be marked with the same reference numerals, and their descriptions will be omitted. In addition, the loading device 70 is an example of a media loading device, provided in place of the loading device 30 in the printer 10 of Embodiment 1. Therefore, the description of the printer 10 will be omitted.

[0122] The corrective part 82 is provided in a manner that allows it to be displaced to both a corrective position and a retracted position. In other words, the corrective part 82 can be displaced from one of the corrective position and the retracted position to the other by rotation.

[0123] The correction position is the position of the correction section 82 when it corrects the curling of the single sheet of PS paper.

[0124] The yielding position is the position of the corrective part 82 when it leaves the corrective position.

[0125] like Figure 5 As shown, the loading device 70 has a rotating shaft 61 at the end position of the first frame 68A in the +Y direction, which rotatably supports the second frame 68B and the straightening part 82. Furthermore, the loading device 70 includes a motor 77 and a control unit 26.

[0126] A gear (not shown) is mounted on the end of the rotating shaft 61 in the +X direction.

[0127] The motor 77 is an example of a drive unit that drives the correction unit 82 to either the correction position or the retraction position by driving the second frame 68B relative to the first frame 68A. Furthermore, the motor 77 rotates a gear located at the end of the rotation shaft 61 in the +X direction. The drive of the motor 77 is controlled by the control unit 26.

[0128] When the rotary button (not shown) is operated, the control unit 26 activates the motor 77, thereby displacing the straightening unit 82 towards the retracted position. Furthermore, when the extend button (not shown) is operated, the control unit 26 activates the motor 77, thereby displacing the straightening unit 82 towards the straightening position.

[0129] The control unit 26 can also control the drive of the motor 77 according to the type and size of the paper P. The type of paper P includes its material and thickness. The size of the paper P refers to its longitudinal and transverse dimensions when viewed from an out-of-plane perspective.

[0130] Specifically, the control unit 26 performs the following control: when the size of the paper P is small, the straightening unit 82 is placed in the retracted position; when the size of the paper P is large, the straightening unit 82 is placed in the straightening position.

[0131] Furthermore, the control unit 26 performs control such that, when the paper P is a thin paper with a thickness thinner than the set thickness, and the ink Q is used to record on the paper P at a higher density than the set density, the correction unit 82 is positioned in the correction position. High-density recording means recording in a manner where the image density of the image recorded on the paper P is higher than the set density.

[0132] The control unit 26 performs control such that, when the paper P is thicker than thin paper, the correction unit 82 is positioned in the retracted position. Furthermore, the control unit 26 performs control such that, when the paper P is photographic paper, the correction unit 82 is positioned in the corrected position.

[0133] According to the loading device 70, since the control unit 26 controls the drive of the motor 77 according to the single sheet PS and switches the position of the straightening unit 82, when using a single sheet PS with relatively low rigidity, the straightening unit 82 is no longer configured in the retracted position.

[0134] According to the loading device 70, even if the paper is swollen due to the ink Q, resulting in a larger curl in the paper, the curl of the paper can still be corrected because the correcting part 82 is in the correcting position.

[0135] Implementation Method 2

[0136] Next, the loading device 90 of Embodiment 2, which is an example of a media loading device, will be described with reference to the accompanying drawings. Furthermore, parts common to the loading device 30 of Embodiment 1 will be labeled with the same reference numerals, and their descriptions will be omitted. In addition, the loading device 90 is provided in place of the loading device 30 in the printer 10 of Embodiment 1. Therefore, the description of the printer 10 will be omitted.

[0137] exist Figure 8 The loading device 90 is shown in the figure. The loading device 90 is located in the loading device 30 ( Figure 5 Replacement of the corrective part 82 in ) Figure 5 The corrective part 92 is provided in a manner that allows for the correction of the load. In addition, the parts of the loading device 90 other than the corrective part 92 are the same as those of the loading device 30.

[0138] The corrective section 92 extends from the downstream end 66A of the opposing section 66 to a position in the -Z direction relative to the transverse reference line M. In other words, in the Z direction, the height position of the downstream end 92A of the corrective section 92 in the +Y direction is lower than the height position of the downstream end 42A of the mounting section 42. Furthermore, the height position of the downstream end 92A corresponds to the lower end position in the Z direction of the corrective section 92.

[0139] Specifically, as an example, the straightening unit 92 comprises four straightening plates 94 spaced apart in the X direction, and an upper plate 95 covering and connecting the four straightening plates 94 in the X direction from the +Z direction. Each of the four straightening plates 94 has a contact surface 96 that contacts the single sheet of paper (PS). That is, the straightening unit 92 has four contact surfaces 96. Furthermore, in Figure 8 In the image, a correction section 92 is shown.

[0140] Four contact surfaces 96 are arranged at intervals in the X direction, which intersects both the +Y and Z directions, and contact both ends of the single sheet PS in the X direction. Furthermore, the four contact surfaces 96 extend in the intersecting direction relative to the +Y direction, with their Z-direction position decreasing from upstream to downstream. Moreover, the four contact surfaces 96 extend in a straight line when viewed from the X direction. That is, the four contact surfaces 96 are inclined surfaces.

[0141] Point D is designated as the upstream endpoint in the +Y direction on the contact surface 96 when viewed from the X direction. Point D lies on the longitudinal reference line N. Furthermore, point F is designated as the downstream endpoint in the +Y direction on the contact surface 96. Point F is the point that becomes the lower end of the straightening plate 94 in the Z direction. Additionally, point F is located relative to point E in both the +Y and -Z directions. The contact surface 96 is represented by the line segment DF.

[0142] When viewed from the X direction, as an example, the tilt angle of the contact surface 96 relative to the XY plane is set to the tilt angle θ described above.

[0143] Next, the function of the loading device 90 will be explained.

[0144] According to the loading device 90, since the height position of the downstream end 92A of the straightening section 92 is lower than that of the downstream end 42A of the mounting section 42, it is possible to suppress the situation where a portion of the single sheet of paper PS with relatively low rigidity passes through the lower end of the straightening section 92 in the Z direction and travels in the +Y direction.

[0145] Implementation Method 3

[0146] Next, the loading device 100 of Embodiment 3, which is an example of a media loading device, will be described with reference to the accompanying drawings. Furthermore, parts common to the loading devices 30 and 90 will be labeled with the same reference numerals, and their descriptions will be omitted. In addition, the loading device 100 is provided in place of the loading device 30 in the printer 10 of Embodiment 1. Therefore, the description of the printer 10 will be omitted.

[0147] exist Figure 9 The loading device 100 is shown in the figure. The loading device 100 is configured to be loaded in the loading device 30 ( Figure 5 Motor 77 was removed from the document. Figure 5 A torsion spring 102 is installed on the rotating shaft 61. In other words, the loading device 100 is designed so that the straightening unit 82 can be rotated manually. Furthermore, the loading device 100 includes a button (not shown). When the straightening unit 82 is rotated manually, pressing this button releases the pressure on the torsion spring 102 (described later), thereby allowing the straightening unit 82 to rotate.

[0148] The torsion spring 102 is an example of a pressing member, which presses the straightening part 82 downward in the Z direction. Specifically, the torsion spring 102 has a winding part 103, a first arm part 104, and a second arm part 105. A rotating shaft 61 is inserted into the winding part 103.

[0149] The first arm 104 extends in one direction from one end of the winding portion 103. Furthermore, a portion of the first arm 104 is mounted on the first frame 68A.

[0150] The second arm 105 extends from the other end of the winding portion 103 in a direction different from the stated direction. Furthermore, a portion of the second arm 105 is mounted on the second frame 68B.

[0151] In this way, the torsion spring 102 is installed around the rotating shaft 61, thereby pressing the straightening part 82 downward in the Z direction.

[0152] In addition, in order to prevent the second frame 68B from rotating as required, a blocking member (not shown) is provided on the first frame 68A.

[0153] Next, the function of the loading device 100 will be explained.

[0154] When a rigid sheet of paper PS comes into contact with the contact surface 86 of the straightening part 82, the straightening part 82 may experience a positional shift in the +Y direction due to the relatively strong squeezing force exerted on the sheet of paper PS.

[0155] Here, according to the loading device 100, since the squeezing force from the single sheet of paper PS is resisted not only by the reaction force generated by the self-weight of the straightening part 82 but also by the pressing force of the torsion spring 102, the positional deviation of the straightening part 82 can be suppressed.

[0156] Furthermore, in a structure like Embodiment 2, where the straightening section 82 extends from the downstream end 66A of the opposing section 66 to a position that is in the -Z direction compared to the horizontal reference line M, when a single sheet of paper PS with high rigidity that does not require straightening is passed through the position of the straightening section 82, the rigidity of the single sheet of paper PS can resist its own weight, or its own weight and pressing force, thereby pushing the straightening section 82 away in the +Y direction and allowing it to pass through.

[0157] Although the printer 10, loading device 30, 70, 90, and 100 involved in Embodiments 1 to 3 of the present invention are based on the case having the structure described above, it is self-evident that changes or omissions of local structures can be made without departing from the spirit of the present invention.

[0158] Variations

[0159] Next, the loading device 110, a modified example of the loading device 90 in Embodiment 2, will be described with reference to the accompanying drawings. Furthermore, parts common to all parts of the loading device 90 will be marked with the same symbols, and their descriptions will be omitted.

[0160] exist Figure 10 The loading device 110 is shown in the figure. The loading device 110 is positioned within the loading device 90 ( Figure 8 ) replaces the contact surface 96 ( Figure 8 It has a contact surface 112 in a manner that allows it to be in contact with other surfaces.

[0161] The contact surface 112 is a curved surface, represented by a curve S that is concave towards the +Y and +Z directions when viewed from the X direction. The intersection of curve S and the horizontal baseline M is designated as point G. In other words, curve S extends from point D to point F, and point G lies between points D and F within curve S. In this manner, compared to a structure where the contact surface 112 is an inclined surface, the timing delay of the contact between the sheet paper PS and the contact surface 112 by making the contact surface 112 curved can suppress the situation where the sheet paper PS contacts the contact surface 112 at an earlier time and droops in the -Z direction.

[0162] Other variations

[0163] In the loading device 30, the straightening part 82 may also be provided in the device body 31 at a location other than the opposing part 66. For example, the straightening part 82 may be supported by the base 32. Furthermore, the straightening part 82 may also be supported by the central or upstream part in the +Y direction of the opposing part 66.

[0164] The rotation of the rotating part 68 can also be carried out manually without the use of the motor 77.

[0165] It can also be structured as follows, that is, the opposing part 66 is only composed of the fixing part 67, and the correcting part 82 is only located at the correcting position.

[0166] The position of the downstream end 66A may not be aligned with the position of the downstream end 42A.

[0167] In the loading device 30, when the single sheet of paper PS is thin paper, the correction section 82 can be positioned in the correction position regardless of the recording density.

[0168] The corrective part 82 can also be configured as a portion extending in the X direction. Correspondingly, the contact surface 86 can also be a surface. Furthermore, the contact surface 86 can also be a curved surface when viewed from the X direction.

[0169] The mounting surface 62 may also consist of only a flat surface 64.

[0170] In addition, loading devices 70, 90, 100, and 110 can also be configured in the same way as loading device 30 by removing a portion of each structure.

[0171] The recording section 18 can also be either a serial recording head or a line recording head.

[0172] The processing device is not limited to an inkjet printer 10, but can also be an electronic photo printer. Furthermore, the processing device is not limited to a printer; for example, it can also be a device for coating the surface of a medium.

[0173] The arrangement of the paper P in the loading devices 30, 90, 100, and 110 is not limited to a center alignment method in which the center of the device in the X direction is aligned with the center of the paper P. It can also be a side alignment method in which the paper P is arranged to be close to the +X direction or the -X direction.
