Summary of the Invention

Problems to be Solved by the Invention

[0004] The medium receiving unit of the processing device of Patent Document 1 has a sheet-like receiving member that can be housed inside the housing and a rotating shaft, and is configured to be able to receive the medium discharged from the housing by feeding out the receiving member from the rotating shaft. In a medium receiving unit having such a configuration, depending on the material and flexibility of the receiving member, there is a possibility that the receiving member may not be fed out normally. As an example of this, at the initial stage of feeding out the receiving member, the receiving member may jump upward vigorously and get caught on an operation unit or the like, and then, when the receiving member wound around the rotating shaft is fed out due to the movement of the operation unit, the outer receiving member wound around the rotating shaft may not follow the rotation of the rotating shaft or the rotation of the inner receiving member. As another example, when the receiving member comes into contact with a component of the processing device, the frictional resistance may be too large with respect to the mass of the receiving member, making it difficult for the receiving member to fall, and the amount of the receiving member fed out may become insufficient. [Means for solving the problem]

[0005] The present invention, for solving the above problems, comprises a processing unit housed in a housing for processing a medium, and a medium receiving unit for receiving the medium discharged from the housing, wherein the medium receiving unit includes a flexible sheet-like receiving member, a pivot shaft provided inside the housing to which one end of the receiving member is connected, an operating unit to which the other end of the receiving member is connected and which is provided to be detachable from the pivot shaft, and a unit that protrudes from the housing so as to be detachable in the direction of movement along the direction of separation of the operating unit from the pivot shaft, and supports both ends of the operating unit. The device comprises a pair of support parts, a rack provided on at least one of the pair of support parts, and a pivot shaft gear provided on the pivot shaft and rotating in conjunction with the movement of the rack, wherein the receiving member is wound onto the pivot shaft and stored inside the housing when the operating part approaches the pivot shaft, and is unwound from the pivot shaft and hangs down to receive the medium when the operating part moves away from the pivot shaft, and holds a weight closer to the other end than the midpoint between the one end and the other end in the forward and backward direction.

[0006] Furthermore, the recording device of the present invention for solving the above problems comprises a recording unit housed in a housing and performing recording on a medium, and a medium receiving unit for receiving the medium discharged from the housing, wherein the medium receiving unit comprises a flexible sheet-like receiving member, a pivot shaft provided inside the housing to which one end of the receiving member is connected, an operating unit to which the other end of the receiving member is connected and which is provided so as to be detachable from the pivot shaft, and a support that protrudes from the housing so as to be detachable in the direction of movement along the direction of separation of the operating unit from the pivot shaft, and supports both ends of the operating unit. The device comprises a pair of support parts, a rack provided on at least one of the pair of support parts, and a pivot shaft gear provided on the pivot shaft and rotating in conjunction with the movement of the rack, wherein the receiving member is wound onto the pivot shaft and stored inside the housing when the operating part approaches the pivot shaft, and is unwound from the pivot shaft and hangs down to receive the medium when the operating part moves away from the pivot shaft, and holds a weight closer to the other end than the midpoint between the one end and the other end in the forward and backward direction.

[0008] First, the present invention will be described in general terms. A first aspect of the present invention for solving the above problems comprises a processing unit housed in a housing for processing a medium, and a medium receiving unit for receiving the medium discharged from the housing, wherein the medium receiving unit includes a flexible sheet-like receiving member, a pivot shaft provided inside the housing to which one end of the receiving member is connected, an operating unit to which the other end of the receiving member is connected and which is provided to be detachable from the pivot shaft, and a pair of support units that protrude from the housing so as to be detachable in a direction along the direction in which the operating unit moves away from the pivot shaft, and support both ends of the operating unit, wherein the receiving member is wound onto the pivot shaft when the operating unit approaches the pivot shaft and stored inside the housing, and is unwound from the pivot shaft when the operating unit moves away from the pivot shaft and hangs down to be able to receive the medium, and holds a weight closer to the other end than an intermediate position between the one end and the other end in the direction of movement.

[0009] According to this aspect, the sheet-like receiving member for receiving the medium is configured such that when the operation portion approaches the rotation axis, it is wound around the rotation axis and stored inside the housing, and when the operation portion moves away from the rotation axis, it is fed out from the rotation axis and hangs downward to be able to receive the medium. A weight is held closer to the other end than the intermediate position between one end and the other end in the advancing and retreating direction, that is, closer to the operation portion in the advancing and retreating direction. In the initial stage of feeding out the receiving member, a feeding-out failure of the receiving member is likely to occur particularly. However, by holding the weight closer to the operation portion in the advancing and retreating direction, in the initial stage of feeding out the receiving member, it is possible to effectively feed out the receiving member from the rotation axis while hanging it downward by utilizing the gravity of the weight. Therefore, the receiving member can be suitably fed out.

[0010] The processing apparatus according to the second aspect of the present invention is characterized in that, in the first aspect, the receiving member has a bag portion, and the weight is stored in the bag portion.

[0011] According to this aspect, the weight is stored in the bag portion of the receiving member. For this reason, it is possible to suppress the weight from coming off the receiving member.

[0012] The processing apparatus according to the third aspect of the present invention is characterized in that, in the second aspect, the weight is movable inside the bag portion.

[0013] According to this aspect, the weight is movable inside the bag portion. By adopting such a configuration, for example, when feeding out the receiving member, it becomes possible to continuously position the weight easily on the lower side in the vertical direction in the bag portion, and the receiving member can be fed out particularly suitably.

[0014] The processing apparatus according to the fourth aspect of the present invention is characterized in that, in the second or third aspect, a plurality of the weights are provided, and the plurality of weights are separately stored in the plurality of bag portions.

[0015] According to this aspect, there are a plurality of weights, and the weights are separately stored in a plurality of bag portions. By adopting such a configuration, for example, when the receiving member is extended, the receiving member can be extended in a well-balanced manner in the width direction (axial direction of the rotation axis) intersecting the advancing and retreating direction.

[0016] The processing apparatus according to the fifth aspect of the present invention is characterized in that, in any one of the first to third aspects, the weight has a metal.

[0017] According to this aspect, the weight has a metal. Therefore, a strong and small-sized weight can be obtained.

[0018] The processing apparatus according to the sixth aspect of the present invention is characterized in that, in any one of the first to third aspects, the weight is rod-shaped.

[0019] According to this aspect, the weight is rod-shaped. By adopting such a configuration, for example, when the receiving member is extended, the receiving member can be extended in a well-balanced manner in the width direction (axial direction of the rotation axis) intersecting the advancing and retreating direction.

[0020] The processing apparatus according to the seventh aspect of the present invention is characterized in that, in any one of the first to third aspects, the weight is spherical. [[ID=​​​​​​​​​According to this embodiment, at least a portion of the surface of the weight is made of resin. Therefore, for example, when the extended receiving member collides with the mounting surface of the processing device, the weight also collides with the mounting surface via the receiving member, and it is possible to suppress the loudness of the collision sound at that time.

[0024] The processing apparatus according to the ninth aspect of the present invention is characterized in that, in the first aspect, the weight is a sheet member sewn onto the receiving member.

[0025] According to this embodiment, the weight is a sheet member sewn onto a receiving member. Therefore, the entire weight can be made flexible. Furthermore, by forming the sheet member, for example by sewing onto the receiving member, the weight can be formed without preparing any new or separate constituent materials.

[0026] The processing apparatus according to the tenth aspect of the present invention is characterized in that, in the ninth aspect, the seams of the sheet member are formed along the axial direction of the pivot axis.

[0027] According to this embodiment, the seams of the sheet member are formed along the axial direction of the pivot axis. The areas where the sheet members are overlapped and sewn become stiffer than other areas, reducing flexibility and making the receiving member more prone to distortion. However, by forming the seams along the axial direction of the pivot axis, distortion of the receiving member as viewed from the direction of gravity due to reduced flexibility can be suppressed. By suppressing distortion of the receiving member as viewed from the direction of gravity, the receiving member can be extended in a balanced manner in the width direction (axial direction of the pivot axis).

[0028] An apparatus according to an eleventh aspect of the present invention is characterized in that, in any one of the first to third aspects, it comprises a rack provided on at least one of the pair of support parts, and a pivot shaft gear provided on the pivot shaft and rotating in conjunction with the movement of the rack.

[0029] According to this embodiment, the device includes a rack provided on at least one of a pair of support parts, and a pivot shaft gear provided on the pivot shaft that rotates in conjunction with the movement of the rack. With this configuration, a configuration in which the pivot shaft rotates in conjunction with the operation of the operating part can be easily created.

[0030] A processing apparatus according to a twelfth aspect of the present invention is characterized in that, in the eleventh aspect, it has a speed-increasing mechanism between the rack and the pivot shaft gear that increases the speed of rotation of the pivot shaft gear, thereby increasing the amount of the receiving member extended to be greater than the amount of movement of the pair of support parts.

[0031] According to this embodiment, a speed-increasing mechanism is provided between the rack and the pivot shaft gear. With this configuration, the need to enlarge the pivot shaft for winding up the receiving member is eliminated, and the device can be made smaller.

[0032] A processing apparatus according to a thirteenth aspect of the present invention is characterized in that, in any one of the first to third aspects, the pivot shaft is configured to be rotatable by more than half a turn from a position that allows the amount of the receiving member to be extended to the maximum extent.

[0033] According to this embodiment, the pivot shaft is configured to rotate by more than half a turn from the position where the amount of the receiving member extended can be maximized. When extending the receiving member, the frictional resistance when the receiving member comes into contact with the components of the processing device tends to increase, making it difficult to extend the receiving member. However, with this configuration, the receiving member can be extended smoothly even at the end of the extension process.

[0034] A recording device according to a 14th aspect of the present invention comprises a recording unit housed in a housing and performing recording on a medium, and a medium receiving unit for receiving the medium discharged from the housing, wherein the medium receiving unit comprises a flexible sheet-like receiving member, a pivot shaft provided inside the housing to which one end of the receiving member is connected, an operating unit to which the other end of the receiving member is connected and which is provided so as to be detachable from the pivot shaft, and a pair of support units that protrude from the housing so as to be detachable in a forward and backward direction along the direction in which the operating unit moves away from the pivot shaft, and support both ends of the operating unit, wherein the receiving member is wound onto the pivot shaft and housed inside the housing when the operating unit approaches the pivot shaft, and is unwound from the pivot shaft and hangs down so as to be detachable from the pivot shaft when the operating unit moves away from the pivot shaft, and holds a weight closer to the other end than an intermediate position between the one end and the other end in the forward and backward direction.

[0035] In this embodiment, the sheet-like receiving member that receives the medium is wound onto the pivot shaft and stored inside the housing when the operating part approaches the pivot shaft, and when the operating part moves away from the pivot shaft, it is unwound from the pivot shaft and hangs down to receive the medium. In this configuration, a weight is held closer to the other end than the midpoint between the two ends in the forward and backward direction, that is, closer to the operating part in the forward and backward direction. In the initial stages of unwinding the receiving member, problems with unwinding the receiving member are particularly likely to occur, but by holding the weight closer to the operating part in the forward and backward direction, the weight's gravity can be used to effectively unwind the receiving member from the pivot shaft and hang down in the initial stages of unwinding the receiving member. Therefore, the receiving member can be unwound smoothly.

[0036] [Example 1] Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings. First, the schematic configuration of the recording device 10A of Embodiment 1, which is a processing device according to an embodiment of the present invention, will be described with reference to Figures 1 to 9. The coordinates indicated in the drawings assume that the recording device 10A is placed on a horizontal mounting surface, and the three mutually orthogonal virtual axes are the X axis, Y axis, and Z axis. The X axis is a virtual axis parallel to the left-right direction of the recording device 10A. The Y axis is a virtual axis parallel to the front-back direction of the recording device 10A. The Z axis is a virtual axis parallel to the height direction of the recording device 10A. The tip side of the arrows representing the X axis, Y axis, and Z axis is the "+ side", and the base side is the "- side". The recording device 10A includes a recording unit 30 as a processing unit that records on a medium. The recording device 10A of this embodiment is a large-format printer that records using an inkjet method by unwinding a long medium 22 wound in a roll. A large-format printer is a printer capable of recording on long media with a width of 297 mm or more, which corresponds to the short side width of A3 size.

[0037] As shown in Figures 1, 2, and 3, the recording device 10A includes a recording unit 30 housed in a housing 12 that records onto a medium 22, and a medium receiving unit 60 that receives the medium 22 discharged from the housing 12.

[0038] The recording device 10A has a roughly rectangular prism-shaped housing 12 that is elongated in the left-right direction. The housing 12 has a front wall 13, a rear wall 14, a first side wall 15, a second side wall 16, and a top wall 17. The housing 12 is connected to a base frame 19 which is supported by legs 11. The recording device 10A is installed on the installation surface S via the legs 11. In the recording device 10A, the Z direction, where the base frame 19 and the top wall 17 face each other, is the height direction of the recording device 10A. The X direction, where the first side wall 15 and the second side wall 16 face each other, is the left-right direction of the recording device 10A. The Y direction, where the front wall 13 and the rear wall 14 face each other, is the front-rear direction of the recording device 10A. When the recording device 10A is placed on a horizontal plane, the Z direction is parallel to the vertical line. The X direction corresponds to the width direction and also to the axial direction of the pivot axis 65, which will be described later.

[0039] Inside the housing 12, in addition to a recording unit 30 for recording onto the medium 22, there is a storage unit 20 for housing a roll body 25 in which the medium 22 is wound in a cylindrical shape, a transport unit 40 for transporting the medium 22, and a cutting unit 50 for cutting the medium 22.

[0040] Multiple openings are formed in the front wall 13 of the housing 12. A roll body storage opening 27 for housing the roll body 25 is formed on the base frame 19 side below the front wall 13. In addition, an opening 53 is formed above the roll body storage opening 27, which has the functions of a paper discharge opening for discharging the recorded medium 22 and an operation opening for unwinding a receiving member 67, which will be described later, for receiving the discharged medium 22. The medium 22 is discharged from the upper side of the opening 53, and the receiving member 67 is unwinded from the lower side of the opening 53. In this embodiment, a configuration in which the paper discharge opening and the unwinding opening are formed in a single opening 53 is illustrated, but a configuration in which the paper discharge opening and the operation opening are provided independently is also possible.

[0041] The housing section 20 houses a cylindrical roll body 25 formed by winding a long medium 22 around a core member 23, which is detachably housed through a roll body housing opening 27. In this embodiment, the housing section 20 is configured to house two roll bodies 25 that are long in the X direction, arranged side by side in the Z direction. A pair of holding members 28 are attached to both ends of the roll body 25 to rotatably hold it relative to the housing section 20. When the roll body 25 is rotated, the medium 22 wound around the roll body 25 is fed out toward the rear wall 14 inside the housing 12.

[0042] The conveying unit 40 conveys the medium 22 discharged from the roll body 25. The conveying unit 40 has a conveying path forming unit 41, an intermediate roller 42, and a conveying roller 43. The conveying path forming unit 41 is provided corresponding to each of the two roll bodies 25. The conveying path forming unit 41 is located on the rear wall 14 side with respect to each of the two roll bodies 25 housed in the housing unit 20. The conveying path forming unit 41 forms a conveying path 44 that guides the medium 22 discharged from the roll body 25 by the rotational drive of the roll body 25 toward the rear wall 14 side of the housing 12.

[0043] The intermediate roller 42 and the transport roller 43 transport the medium 22 that has passed through the transport path 44 to the recording unit 30. The intermediate roller 42 and the transport roller 43 consist of a drive roller and a driven roller, which are a pair of rollers supported so as to be rotatable with an axis along the X direction as the pivot axis. The intermediate roller 42 and the transport roller 43 sandwich the medium 22 between the drive roller and the driven roller, respectively. When the drive roller of the intermediate roller 42 and the transport roller 43 is rotated, the medium 22 is transported to the support base 31 through the transport path 44, and also transported on the support base 31 from the rear wall 14 side to the front wall 13 side. Although Figure 3 shows the state in which the medium 22 is fed out from both of the two roll bodies 25, during actual recording the medium 22 is fed out from one of the two roll bodies 25.

[0044] The recording unit 30 comprises a support base 31, a guide shaft 32, a carriage 33, and a recording head 34. The support base 31 is located on the upper wall 17 side of the housing unit 20. The support base 31 is a plate-shaped member extending in the X direction within the housing 12 and supports the medium 22 transported by the transport unit 40. The guide shaft 32 is located on the upper wall 17 side of the support base 31. The guide shaft 32 is a rod-shaped member extending in the X direction. The guide shaft 32 slidably supports the carriage 33.

[0045] The recording head 34 is mounted on the carriage 33. The recording head 34 is located on the support base 31 side relative to the carriage 33. The recording head 34 is configured to reciprocate along the guide shaft 32 together with the carriage 33. The recording head 34 is connected to an ink cartridge 35 by a flexible tube (not shown). The cartridge 35 is housed in a position on the second side wall 16 side of the housing section 20 and on the upper wall 17 side of the housing section 20. The recording head 34 performs recording on the medium 22, which is supported by the support base 31, by ejecting ink onto the medium 22 while moving in the X direction.

[0046] The cutting section 50 is located on the front wall 13 side of the recording section 30. The cutting section 50 has a fixed blade and a movable blade that moves relative to the fixed blade, and cuts the medium 22 located between the fixed blade and the movable blade. The cut medium 22 is supported by a paper discharge slot member 51 that guides the medium 22 towards the upper side of an opening 53 formed in the front wall 13, and is discharged to the outside of the housing 12.

[0047] Furthermore, the recording device 10A has an input unit 59. The input unit 59 is provided on the upper surface of the upper wall 17 of the housing 12. The input unit 59 is located at the corner formed by the part where the front wall 13 is connected to the upper wall 17 and the part where the second side wall 16 is connected to the upper wall 17. The input unit 59 is composed of, for example, a liquid crystal display device with a touch panel, and is used when the user inputs various types of information.

[0048] As shown in Figure 3 and other figures, the media receiving section 60 consists of an operating section 61, a support section 63, a pivot shaft 65, a receiving member 67, and the like. The pivot shaft 65 is located inside the housing 12, between the storage section 20 and the paper discharge slot member 51. The pivot shaft 65 is cylindrical in shape, elongated in the X direction, and its length is longer than the width of the media 22. The pivot shaft 65 is rotatably supported relative to the housing 12.

[0049] The operating section 61 is a rod-shaped member that is long in the X direction. Both ends of the operating section 61 are supported by a pair of support parts 63 that protrude from the front wall 13 side of the housing 12 so as to be able to move back and forth in the +Y direction. The pair of support parts 63 protrude to the outside of the housing 12 from between the pivot shaft 65 and the housing 20. In other words, the operating section 61 is able to move away from the housing 12, and can be displaced between a mounted state attached to the housing 12 and a separated state separated from the housing 12 as the pair of support parts 63 move back and forth.

[0050] The receiving member 67 is a long, flexible, sheet-like member. As shown in Figures 3 to 6, one end 67b of the receiving member 67 is connected to the pivot shaft 65, and the other end 67c of the receiving member 67 is connected to the connection part 61a of the operating part 61. The pivot shaft 65 is configured to rotate in the forward or reverse direction in conjunction with the movement of the support part 63. Here, as shown in Figures 2 to 5, a bag portion 101 is attached to the receiving member 67, and a rod-shaped weight 100A is stored in the bag portion 101 as a weight 100.

[0051] As shown in Figures 7 and 8, a rack 64 is provided on at least one of the pair of support parts 63. The rack 64 is a flat bar with multiple teeth cut at equal pitches. In the recording device 10 of this embodiment, the rack 64 is provided on the -Z side surface of both support parts 63. On the other hand, the pivot shaft 65 is provided with a pivot shaft gear 66 that rotates in conjunction with the movement of the rack 64. Furthermore, a speed-increasing mechanism 70 is provided between the rack 64 and the pivot shaft gear 66 to increase the speed of rotation of the pivot shaft gear 66.

[0052] The speed-increasing mechanism 70 has a first composite gear 71 and a second composite gear 74, which are composite gears with different numbers of teeth stacked on top of each other. The first composite gear 71 has a first gear 72 that meshes with the rack 64 and a second gear 73 that has a larger diameter and more teeth than the first gear 72, both formed on the same shaft. When the rack 64 and the first gear 72 mesh, the linear movement of the support part 63 as it moves back and forth is converted into rotational force for the first composite gear 71. The second composite gear 74 has a third gear 75 that meshes with the second gear 73 and has a smaller diameter and fewer teeth than the second gear 73, and a fourth gear 76 that has a larger diameter and more teeth than the third gear 75, both formed on the same shaft.

[0053] For example, if the number of teeth of the second gear 73 is twice the number of teeth of the first gear 72, the third gear 75 that engages with the second gear 73 will rotate twice as fast as if the first gear 72 and the third gear 75 were directly meshed together. In other words, the first composite gear 71 increases the rotational speed of the second composite gear 74. Similarly, the second composite gear 74 increases the rotational speed of the pivot shaft gear 66. In this embodiment, a speed-increasing mechanism 70 composed of two first composite gears 71 and a second composite gear 74 is illustrated, but a speed-increasing mechanism composed of one composite gear or three or more composite gears may also be used. Furthermore, a speed-increasing mechanism composed of a combination of multiple spur gears of different sizes and diameters with different numbers of teeth may also be used.

[0054] The receiving member 67 is wound onto the pivot shaft 65 and housed inside the housing 12 when the operating unit 61 is displaced from the separated state shown in Figures 3 and 6 through the state shown in Figure 5 to the mounted state shown in Figure 4. The receiving member 67 is also unwound from the pivot shaft 65 to the outside of the housing 12 via the lower side of the opening 53 when the operating unit 61 is displaced from the mounted state shown in Figure 4 through the state shown in Figure 5 to the separated state shown in Figures 3 and 6, and becomes capable of receiving the media 22 discharged from the upper side of the opening 53. In this embodiment, the recording device 10 is configured such that the amount unwound of the receiving member 67 from the pivot shaft 65 is greater than the amount of movement of the pair of support parts 63 in the +Y direction, by means of the speed-increasing mechanism 70. As a result, the receiving member 67 forms slack between the operating unit 61 and the pivot shaft 65.

[0055] The operating unit 61 has a front plate 62 that forms part of the front wall 13 of the housing 12 when it is mounted, as shown in Figure 4. The front plate 62 is a plate-shaped member that is long in the X direction and rises in the +Z direction from the operating unit 61. At least a portion of the opening 53 is covered by the front plate 62 when the operating unit 61 is mounted. As shown in Figure 4, the front plate 62 forms the same surface as the front wall 13 when it is mounted. In this embodiment, the lower part of the opening 53 from which the receiving member 67 is extended is covered by the front plate 62.

[0056] In this embodiment, a configuration in which the extension amount of the receiving member 67 is greater than the extension amount of the support portion 63 is illustrated using the speed-increasing mechanism 70, but the embodiment is not limited to this. For example, by using a pivot shaft having an outer circumference longer than the extension amount of the support portion 63 required to rotate the pivot shaft once, a configuration in which the extension amount of the receiving member 67 is greater than the extension amount of the support portion 63 can be realized.

[0057] As shown in Figures 4 to 6, the media receiving section 60 has a contact section 80 and an auxiliary roller 85. The contact section 80 contacts the outer circumferential surface 67a of the roll-shaped receiving member 67 wound around the pivot shaft 65, pressing the receiving member 67 against the pivot shaft 65. The contact sections 80 are provided at both ends in the axial direction, i.e., the X direction, of the pivot shaft 65.

[0058] The contact section 80 includes a contact roller 81 and an arm 83. The contact roller 81 is a driven roller that contacts and moves with the outer circumferential surface 67a of the receiving member 67, which rotates with the pivot shaft 65 when it is wound onto or unwound by the pivot shaft 65. The arm 83 is located above the pivot shaft 65. One end of the arm 83 is located in the -Y direction from a vertical line CL1 that intersects the axis of the pivot shaft 65 and is rotatably supported by an arm shaft 84 that extends in the X direction. The other end of the arm 83 is located in the +Y direction from the vertical line CL1 and rotatably supports the contact roller 81 via a contact roller shaft 82. That is, the contact roller 81 contacts the roll-shaped receiving member 67 between a line in the vertical line CL1 that extends in the +Z direction from the axis of the pivot shaft 65 and a line in the horizontal line CL2 that intersects the axis of the pivot shaft 65 and extends in the +Y direction from the axis of the pivot shaft 65.

[0059] The contact roller 81 presses the roll-shaped receiving member 67, which is wound onto the pivot shaft 65, against the pivot shaft 65 by a pressing member (not shown) that presses the arm 83 downward. This allows the contact roller 81 to contact the outer circumferential surface 67a of the receiving member 67, following the radius of the roll-shaped receiving member 67, which changes in accordance with the rotation of the pivot shaft 65. In this embodiment, a configuration in which the contact portion 80 is provided at both ends of the pivot shaft 65 is illustrated, but a configuration in which multiple contact portions are provided in addition to both ends is also possible.

[0060] The auxiliary roller 85 contacts the outer circumferential surface 67a of the roll-shaped receiving member 67 wound onto the pivot shaft 65, thereby pressing the receiving member 67 against the pivot shaft 65. The auxiliary roller 85 is a driven roller that contacts and moves with the outer circumferential surface 67a of the receiving member 67 as it rotates when it is wound onto or unwound from the pivot shaft 65. The auxiliary roller 85 is located below the horizontal line CL2 that intersects the axis of the pivot shaft 65 and is rotatably supported via the auxiliary roller shaft 86. Furthermore, it is preferable that the auxiliary roller 85 be positioned at a location that coincides with the vertical line CL1 that intersects the axis of the pivot shaft 65.

[0061] The auxiliary roller 85 presses the roll-shaped receiving member 67, which is wound around the pivot shaft 65, against the pivot shaft 65 by a pressing member that presses the auxiliary roller shaft 86 upward. This allows the auxiliary roller 85 to contact the outer circumferential surface 67a of the receiving member 67, following the radius of the roll-shaped receiving member 67, which changes in accordance with the rotation of the pivot shaft 65. One or more auxiliary rollers 85 are provided along the X direction of the pivot shaft 65.

[0062] The contact roller 81 and auxiliary roller 85 press the receiving member 67 against the pivot shaft 65, making it easier for the rotation of the pivot shaft 65 to be transmitted not only to the receiving member 67 closest to the pivot shaft 65, but also to the outer circumferential surface 67a. However, in this embodiment, the receiving member 67 is constantly being pulled downward by the weight 100, and tension is applied to the outer circumferential surface 67a of the receiving member 67, pulling it towards the pivot shaft 65. Therefore, the receiving member 67 can be unfurled normally even without the contact roller 81 and auxiliary roller 85. If the contact roller 81 and auxiliary roller 85 are not provided, the parts associated with the contact roller 81 and auxiliary roller 85 are also unnecessary, resulting in cost reduction. In addition, since the contact roller 81 and auxiliary roller 85 do not generate noise when they rotate in conjunction with the unfurling and winding of the receiving member 67, noise is also reduced.

[0063] In this embodiment, a recording device 10A is provided as an example of a processing device equipped with a recording unit 30 that performs recording using an inkjet method, but the device is not limited to this. The processing device may be a recording device other than an inkjet device, a copier, a fax machine, or a multifunction device that has multiple functions of these.

[0064] As described above, the recording device 10A is housed in a housing 12 and comprises a recording unit 30 as a processing unit for processing the medium 22, and a medium receiving unit 60 for receiving the medium 22 discharged from the housing 12. The medium receiving unit 60 comprises a flexible sheet-like receiving member 67, a pivot shaft 65 provided inside the housing 12 to which one end 67b of the receiving member 67 is connected, an operating unit 61 to which the other end 67c of the receiving member 67 is connected and which is provided to be detachable from the pivot shaft 65, and a pair of support parts 63 that protrude from the housing 12 so as to be detachable in the forward / backward direction D shown in Figures 3 to 6 along the direction of separation of the operating unit 61 from the pivot shaft 65 (+Y direction), and support both ends of the operating unit 61. Furthermore, as shown in Figures 7 and 8, the medium receiving unit 60 comprises a rack 64 provided on at least one of the pair of support parts 63, and a pivot shaft gear 66 provided on the pivot shaft 65 that rotates in conjunction with the movement of the rack 64. In Figures 4 to 6, direction D1 corresponds to the direction in which the operating unit 61 enters the housing 12, and direction D2 corresponds to the direction in which the operating unit 61 exits the housing 12.

[0065] Furthermore, any mechanism other than the combination of the rack 64 and the pivot shaft gear 66 can be used, as long as the pivot shaft 65 rotates in conjunction with the movement of the operating unit 61. For example, the operating unit 61 may be supported by one end of a rod-shaped guide member, with the other end of the rod-shaped guide member supported by the housing 12. In this case, when the operating unit 61 moves closer to or further away from the housing 12, the other end of the rod-shaped guide member supported by the housing 12 rotates as a pivot point, and the rotation of the pivot shaft 65 may be linked to the rotation of the rod-shaped guide member.

[0066] Here, the receiving member 67 and the media receiving section 60 will be described in more detail. In this embodiment, the receiving member 67 is wound onto the pivot shaft 65 when the operating section 61 approaches the pivot shaft 65 and stored inside the housing 12, and when the operating section 61 moves away from the pivot shaft 65, it is unwound from the pivot shaft 65 and hangs down to receive the media 22. This allows the media receiving section 60 to be housed in a narrow space, and a processing device with a smaller size can be provided.

[0067] Furthermore, the weight 100A is held closer to the other end 67c than the midpoint between the one end 67b and the other end 67c in the forward / backward direction D, that is, closer to the operating part 61 in the forward / backward direction D. Note that "closer to the other end 67c than the midpoint between the one end 67b and the other end 67c in the forward / backward direction D" means, as shown in Figure 3, "closer to the other end 67c than the midpoint between the one end 67b and the other end 67c in the entire length of the receiving member 67 from one end 67b to the other end 67c". In the initial stages of extending the receiving member 67, defects in extending the receiving member 67 are particularly likely to occur, but as can be seen by referring to Figures 4 and 5, by holding the weight 100A closer to the operating part 61 in the forward / backward direction D, the receiving member 67 can be effectively extended from the rotating shaft 65 and lowered downwards by utilizing the gravity G of the weight 100A in the initial stages when the operating part 61 moves away from the rotating shaft 65 and extends the receiving member 67. Therefore, the recording device 10A can prevent the receiving member 67 from flying out forcefully beyond the operating unit 61 and upward in the +Y direction at the initial stage of unwinding the receiving member 67, thereby preventing the receiving member 67 from getting caught on the operating unit 61, and can unwind the receiving member 67 as shown in Figure 3.

[0068] Furthermore, as shown in Figures 3 to 5, in the recording device 10A, the receiving member 67 has a bag portion 101, and the weight 100A is housed in the bag portion 101. Therefore, the recording device 10A is configured to prevent the weight 100A from coming out of the receiving member 67. Note that the "bag portion" only needs to have a closed area in at least two opposing directions, and there are no particular limitations on the number or arrangement of the open areas. In fact, as in the recording device 10A of this embodiment, there may be no open areas at all, such as the bag portion 101.

[0069] In this embodiment, the weight 100A in the recording device 10A is rod-shaped, as shown in Figure 9, and is housed in the bag portion 101 with its longitudinal direction in the X direction. By making the weight 100 rod-shaped, for example, when unwinding the receiving member 67, the receiving member 67 can be unwinded in a balanced manner in the width direction (the X direction corresponding to the axial direction of the pivot axis) that intersects the forward / backward direction D. Note that the rotation direction of the pivot axis 65 when unwinding the receiving member 67 in the order shown in Figures 4, 5, and 6 is counterclockwise from Figure 4 to Figure 6. Conversely, the rotation direction of the pivot axis 65 when winding the receiving member 67 onto the pivot axis 65 in the order shown in Figures 6, 5, and 4 is clockwise from Figure 4 to Figure 6.

[0070] Furthermore, the bag portion 101 in the recording device 10A of this embodiment is a rectangular sheet member sewn to the receiving member 67 at a seam 102 (shown by a dashed line in the bag portion 101), as shown in Figure 2. The weight 100A is movable within the bag portion 101. With this configuration, for example, when the receiving member 67 is unfurled, the weight 100 can be easily kept positioned vertically downward in the bag portion 101, allowing the receiving member 67 to be unfurled particularly efficiently.

[0071] As shown in Figure 9, the weight 100A consists of a rod-shaped portion 100a and cap portions 100b attached to both ends of the rod-shaped portion 100a. Here, the rod-shaped portion 100a is made of metal. Thus, the weight 100A has metal. For this reason, the weight 100A can be made into a sturdy and compact weight 100.

[0072] On the other hand, the cap portion 100b is made of resin. That is, at least a part of the surface of the weight 100A is made of resin. With this configuration, for example, when the extended receiving member 67 collides with the installation surface S, the weight 100A also collides with the installation surface S via the receiving member 67, but it is possible to suppress the loudness of the collision sound at that time.

[0073] Furthermore, as described above, the recording device 10A of this embodiment includes a rack 64 provided on at least one of a pair of support parts 63, and a pivot shaft gear 66 provided on a pivot shaft 65 that rotates in conjunction with the movement of the rack 64. In addition, a speed-increasing mechanism 70 is provided between the rack 64 and the pivot shaft gear 66 to increase the speed of rotation of the pivot shaft gear 66, thereby increasing the amount of the receiving member 67 unwound to a greater extent than the amount of movement of the pair of support parts 63. With this configuration, a configuration in which the pivot shaft 65 rotates in conjunction with the operation of the operation unit 61 can be easily formed, and the need to enlarge the pivot shaft 65 for winding up the receiving member 67 can be eliminated, thereby making the device smaller.

[0074] In this embodiment, as shown in Figure 6, the pivot shaft 65 is configured to rotate by a further half-turn from the position P1 where the amount of the receiving member 67 can be extended to its maximum when the operating unit 61 is most retracted from the front wall 13 of the housing 12. It is preferable that the pivot shaft 65 be configured to rotate by more than a further half-turn from the position P1 where the amount of the receiving member 67 can be extended to its maximum. At the end of extending the receiving member 67, the frictional resistance when the receiving member 67 contacts the components of the recording device 10 tends to increase, making it difficult to extend the receiving member 67. However, with this configuration, the receiving member 67 can be extended smoothly even at the end of extending the receiving member 67.

[0075] [Example 2] The recording device 10B of Example 2 will be described below with reference to Figures 10 and 11. Figure 10 corresponds to Figure 2 in the recording device 10A of Example 1, and Figure 11 corresponds to Figure 3 in the recording device 10A of Example 1. The recording device 10B of this example is the same as the recording device 10A of Example 1, except for the configuration described below. Therefore, the recording device 10A of this example has the same characteristics as the recording device 10A of Example 1, except for the parts described below. Accordingly, in Figures 10 and 11, components common to Example 1 are indicated by the same reference numerals, and detailed explanations are omitted.

[0076] As described above, in the recording device 10A of Example 1, the weight 100 was a rod-shaped weight 100A. On the other hand, as shown in Figures 10 and 11, in the recording device 10B of this embodiment, the weight 100 is a sheet member 100B that is sewn onto the receiving member 67. Therefore, the entire weight 100 can be made flexible. Furthermore, by forming the sheet member, for example by sewing onto the receiving member 67, the weight 100 can be formed without preparing any new or other constituent materials.

[0077] In this embodiment of the recording device 10B, the seams 102 of the sheet member 100B sewn onto the receiving member 67 are formed at two locations, upper and lower, along the axial direction of the pivot axis 65, i.e., the width direction corresponding to the X direction. The area where the sheet member 100B is sewn becomes stiffer than other areas, reducing flexibility and making the receiving member 67 more prone to distortion. However, by forming the seams 102 along the axial direction of the pivot axis 65, distortion of the receiving member 67 as seen from the direction of gravity due to reduced flexibility can be suppressed. By suppressing distortion of the receiving member 67 as seen from the direction of gravity, the receiving member 67 can be extended in a balanced manner in the width direction (axial direction of the pivot axis). Furthermore, since the seams 102 are not provided at the ends in the width direction, the user can access the bag portion 101 from the ends in the width direction. Therefore, the user can temporarily store various items such as stationery and tools in the bag portion 101.

[0078] In this embodiment, the sheet member 100B is made by folding the same material as the receiving member 67 to make it double-layered, and then sewing it onto the receiving member 67. However, the embodiment is not limited to this configuration, and a sheet member made of a different material than the receiving member 67 may be used, or a sheet member that is not folded or a sheet member that is folded three or more times may be used. Alternatively, a portion of the receiving member 67 itself, which is continuous without a break between one end 67b and the other end 67c, may be folded multiple times so that the folds are aligned with the axial direction of the pivot axis 65, thereby forming a heavier region than other regions, and this folded, heavier region may be used as the weight 100. The folded region of the receiving member 67 is made into the weight 100 by sewing the seam 102 along the axial direction of the pivot axis 65. In this embodiment, since the weight 100 is formed by sewing together flexible material, the position of the weight 100 on the receiving member 67 does not change. The preferred position for forming the weight 100, which is the sheet member 100B, is near the other end 67c of the receiving member 67 and close to the operating part 61. In the initial stage when the operating part 61 moves away from the pivot shaft 65 and extends the receiving member 67, the gravity G of the sheet member 100B can be used to effectively extend the receiving member 67 from the pivot shaft 65 and cause it to hang downwards.

[0079] [Example 3] The recording device 10C of Example 3 will be described below with reference to Figures 12 and 13. Figure 12 corresponds to Figure 2 in the recording device 10A of Example 1, and Figure 13 corresponds to Figure 9 in the recording device 10A of Example 1. The recording device 10C of this example is the same as the recording device 10A of Example 1, except for the configuration described below. Therefore, the recording device 10A of this example has the same characteristics as the recording device 10A of Example 1, except for the parts described below. Accordingly, in Figures 12 and 13, components common to Example 1 and Example 2 are indicated by the same reference numerals, and detailed explanations are omitted.

[0080] As described above, in the recording device 10A of Example 1, the weight 100 was a rod-shaped weight 100A. On the other hand, as shown in Figures 12 and 13, in the recording device 10C of this embodiment, the weight 100 is a spherical weight 100C. With this configuration, for example, when extending the receiving member 67, it becomes possible to easily keep the weight 100 positioned vertically downward in the bag portion 101, and the receiving member 67 can be extended particularly favorably.

[0081] Furthermore, as shown in Figure 12, the recording device 10C of this embodiment has multiple weights 100C, and the multiple weights 100C are housed in multiple bag sections 101. With this configuration, for example, when extending the receiving member 67, the receiving member 67 can be extended in a balanced manner in the width direction (axial direction of the pivot axis 65) that intersects the forward and backward direction D.

[0082] In this embodiment, the weight 100C is composed of a metal sphere 100c inside, and its surface is covered with a resin coating layer 100d. This allows for a compact weight 100 that is robust and has a high specific gravity, and also suppresses the loudness of the impact sound when the weight 100C collides with the installation surface S via the extended receiving member 67. However, the configuration is not limited to this, and for example, the entire spherical weight 100 may be made of metal or resin.

[0083] The present invention is not limited to the embodiments described above, and can be realized in various configurations without departing from its spirit. Furthermore, the technical features in the embodiments corresponding to the technical features in each embodiment described in the summary of the invention can be replaced or combined as appropriate in order to solve some or all of the above-described problems, or to achieve some or all of the above-described effects. In addition, if a technical feature is not described as essential in this specification, it can be deleted as appropriate. [Explanation of Symbols]
