[0008] Hereinafter, the present disclosure will be described based on the embodiment. In each drawing, the same members are given the same reference numerals, and duplicated descriptions are omitted. In this specification, "same", "same", and "simultaneous" do not only mean that they are completely the same. For example, in this specification, "same", "same", and "simultaneous" include cases where they are the same taking into account measurement errors. Also, for example, in this specification, "same", "same", and "simultaneous" include cases where they are the same taking into account manufacturing variations of the members. Also, for example, in this specification, "same", "same", and "simultaneous" include cases where they are the same to the extent that their functions are not impaired. Therefore, for example, "the dimensions of both are the same" refers to the difference in dimensions between the two being within ±5% of the other dimension, particularly preferably within ±3%, taking into account measurement errors and manufacturing variations of the members.

[0009] 1. Embodiment 1 The recording device 11 is, for example, an inkjet printer capable of recording on sheets of printing paper, envelopes, and the like, which are examples of the medium P.

[0010] In each figure, X, Y, and Z represent three spatial axes that are mutually orthogonal. In this specification, the directions along these axes are defined as the X-axis direction, the Y-axis direction, and the Z-axis direction. When specifying a direction, the positive direction is defined as "+" and the negative direction as "-", and the direction is expressed using both positive and negative signs, with the direction indicated by the arrow in each figure being the + direction and the opposite direction of the arrow being the - direction.

[0011] Additionally, the Z-axis direction indicates the direction of gravity, the +Z direction indicates the vertical downward direction, and the -Z direction indicates the vertical upward direction. Additionally, the plane including the X-axis and Y-axis is described as the XY plane, the plane including the X-axis and Z-axis as the XZ plane, and the plane including the Y-axis and Z-axis as the YZ plane. Additionally, the XY plane is a horizontal plane. Furthermore, the three spatial axes of X, Y, and Z, which are not limited to positive and negative directions, will be described as the X-axis, Y-axis, and Z-axis.

[0012] The X-axis direction is an example of a direction intersecting the transport direction of the medium P in the device body 12, i.e., the width direction of the medium P, and is also an example of the width direction of the recording device 11 and the device body 12. The X-axis direction is a horizontal direction along the mounting surface MS, which is a horizontal plane on which the recording device 11 is mounted. As viewed from an operator positioned in front of the recording device 11, the +X direction is the left side and the -X direction is the right side. In this embodiment, the front of the recording device 11 and the device body 12 is the side on which the operation unit 14 is provided.

[0013] The Y-axis direction is the depth direction of the recording device 11 and the device main body 12. The Y-axis direction is the horizontal direction along the mounting surface MS, which is a horizontal plane on which the recording device 11 is mounted. Of the Y-axis directions, the +Y direction is the direction from the rear of the recording device 11 and the device main body 12 to the front of the recording device 11 and the device main body 12, and the -Y direction is the direction from the front of the recording device 11 and the device main body 12 to the rear of the recording device 11 and the device main body 12.

[0014] The Z-axis direction is a normal direction to the placement surface MS, and is the height direction of the recording device 11 and the device body 12. In the following description, the +Z direction may be referred to as "downward" and the -Z direction may be referred to as "upward."

[0015] As shown in FIGS. 1 and 3, the recording device 11 includes a device main body 12 and a reading unit 21.

[0016] The reading unit 21 reads an image of a document. The reading unit 21 is provided on the -Z direction side of the device body 12 in the Z axis direction, above the device body 12.

[0017] The device body 12 includes a housing 13, an operation unit 14, a storage unit 15, and a placement unit 16. In each drawing, a transport path T along which the medium P is transported is indicated by a two-dot chain line, and a reversal path R is indicated by a one-dot chain line.

[0018] The housing 13 includes an operation unit 14 at the center in the X-axis direction of the front surface, which is the surface on the +Y direction side. The housing 13 also includes an opening 17 at the center in the X-axis direction of the front surface, which is on the +Z direction side of the operation unit 14. The housing 13 also includes, inside the housing 13, a feed unit 31, a transport unit 33, a recording unit 40, a liquid container holding unit 18, a cutting unit 60, a discharge unit 45, and a control unit 90. The housing 13 also includes a maintenance unit 50 inside the housing 13, as shown in FIG. 2.

[0019] As shown in FIG. 1, the operation unit 14 has a touch panel display unit, operation buttons, etc., and notifies the user by displaying a message on the display unit.

[0020] The storage unit 15 can store a plurality of media P in a stacked state. The storage unit 15 is a so-called tray in the shape of a box with a bottom that opens on the -Z direction side so that the media P can be placed thereon. The storage unit 15 is disposed at a supply position (see FIG. 3) where the stored media P can be sent out to the transport path T by inserting the tip side of the storage unit 15, which is on the -Y direction side, into the inside of the housing 13 through the opening 17. In other words, the storage unit 15 is detachably provided inside the housing 13.

[0021] As shown in Fig. 3, the storage unit 15 in the supply position is located on the +Z side, vertically below the operation unit 14. Also, the storage unit 15 in the supply position is located on the +Z side, vertically below the cutting unit 60 and the removal units 81, 82 (see Figs. 2 and 4), which will be described later. In other words, the storage unit 15 in the supply position overlaps with the movement areas of the cutting unit 60 and the removal units 81, 82, when viewed from vertically above, which is on the -Z side. The storage unit 15 can be removed from the housing 13, making it possible to set the medium P in the storage unit 15.

[0022] The feeding section 31 includes a feeding roller 32. The feeding roller 32 rotates while in contact with the medium P stored in the storage section 15, thereby feeding the uppermost medium P to the transport path T. The feeding section 31 sends out the medium P stored in the storage section 15 one sheet at a time to the transport path T. In the following description, in the transport direction in which the medium P is transported along the transport path T (see the arrow in FIG. 3), the direction in which the medium P is transported may be referred to as "downstream", and the opposite direction may be referred to as "upstream".

[0023] The medium P sent to the transport path T by the feeding unit 31 is transported along the curved portion of the transport path T. As a result, the medium P is transported along the transport path T while changing the transport direction toward the transport roller pair 35 located downstream in the transport direction.

[0024] The transport unit 33 transports the medium P from upstream to downstream in the transport direction along the transport path T. The transport unit 33 includes a transport path member 34, a transport roller pair 35, a medium support unit 36, a reversing path member 37, and switching units 38 and 39.

[0025] The transport path member 34 forms a curved transport path of the transport path T between the storage unit 15 and the transport roller pair 35.

[0026] The transport roller pair 35 is provided at a position on the transport path T between the transport path member 34 and the medium support unit 36. The transport roller pair 35 rotates with the medium P sandwiched between them, thereby transporting the medium P along the transport path T toward the medium support unit 36 ​​located on the +Y direction side of the transport roller pair 35.

[0027] The Y-axis direction is an example of a transport direction in the transport path T along which the medium P is transported after passing through the transport roller pair 35. In addition, in the transport path T along which the medium P is transported after passing through the transport roller pair 35, the -Y direction is an example of the upstream transport direction, and the +Y direction is an example of the downstream transport direction.

[0028] The medium support unit 36 ​​is provided at a position on the +Y direction side of the transport roller pair 35 on the transport path T. The medium support unit 36 ​​is provided at a position on the -Z direction side of the storage unit 15 and the feeding unit 31. The medium support unit 36 ​​is located on the -Z direction side of the upstream end in the transport direction of the transport path T formed by the transport path member 34. The medium support unit 36 ​​supports at least a portion of the medium P to be recorded by the recording unit 40.

[0029] 2 and 3, the medium support unit 36 ​​is provided with a lead-out unit 36h that leads out, from the medium support unit 36, the ink that is ejected onto an area of ​​the medium support unit 36 ​​that is outside the medium P during recording by the recording unit 40. The lead-out unit 36h is, for example, a plurality of through holes that penetrate the medium support unit 36 ​​in the Z-axis direction.

[0030] Ink ejected onto an area of ​​the medium support unit 36 ​​that is outside the medium P is collected as waste liquid in waste liquid collecting unit 55 provided on the +Z direction side of the medium support unit 36 ​​via outlet unit 36h. Ink collected as waste liquid in waste liquid collecting unit 55 flows into paper powder holding unit 56, described below, via inflow unit 57. This moistens the paper powder inside and within the paper powder holding unit 56, making it possible to prevent paper powder from scattering from the paper powder holding unit 56. Inflow unit 57 is, for example, a flexible tube.

[0031] The reversing path member 37 forms a reversing path R that can transport the medium P transported in the +Y direction of the medium support unit 36 ​​to a position that is an upstream end in the transport direction of the transport path T formed by the transport path member 34. The reversing path member 37 extends in the X-axis direction across the width dimension of the medium P. The reversing path member 37 also extends in the Y-axis direction passing through the +Z direction side of the medium support unit 36 ​​and the waste liquid collection unit 55.

[0032] The +Y end of the reversing path member 37 is located between a first discharge roller pair 46 (described later) and a side wall 62b of the cutting unit 60 in the Y axis direction. The +Y end of the reversing path member 37 is located at the same level as or in the +Z direction as an upper surface of a fixed blade 62 of the cutting unit 60 (described later) in the Z axis direction. The upper surface of the fixed blade 62 is the surface of the fixed blade 62 on the -Z direction side. In addition, the +Y end of the reversing path member 37 is located on the -Z direction of the paper powder retaining unit 56 in the Z axis direction.

[0033] An end of the -Y direction of the reversing path member 37 is connected to an end upstream in the conveying direction of the conveying path member 34. The end of the -Y direction of the reversing path member 37 is located on the -Y direction side of the medium support unit 36 ​​in the Y axis direction. The end of the -Y direction of the reversing path member 37 is located on the +Z direction side of the end of the reversing path member 37 on the +Y direction side. The end of the -Y direction of the reversing path member 37 is located between the medium support unit 36 ​​and the storage unit 15 in the Z axis direction.

[0034] Moreover, the end of the reversing path member 37 on the +Y direction side is located on the +Y direction side of the discharge surface 42 of the recording unit 40. Moreover, the end of the reversing path member 37 on the -Y direction side is located on the -Y direction side of the discharge surface 42 of the recording unit 40. Therefore, the reversing path member 37 is an example of a wall portion WP that separates the paper dust retaining unit 56 and the discharge surface 42 of the recording unit 40 in the Y axis direction. Moreover, the reversing path member 37 covers the direction of the paper dust retaining unit 56 toward the recording unit 40. Therefore, the reversing path member 37 isolates the paper dust retaining unit 56 from the recording unit 40.

[0035] 3. Switching unit 38 is provided at the end of the +Y direction side of reversal path R so as to be rotatable about an axis along the X-axis. Switching unit 39 is provided at the end of the -Y direction side of reversal path R so as to be rotatable about an axis along the X-axis.

[0036] When the switching units 38 and 39 are in the transport position, the medium P can be transported from the storage unit 15 along the transport path T toward the placement unit 16 (see the arrow in FIG. 3). When the switching units 38 and 39 are in the reversing position, the medium P can be transported along the reversing path R from the +Y direction side to the -Y direction side of the reversing path R (see the arrow in FIG. 3).

[0037] The recording unit 40 has a plurality of nozzles N capable of ejecting liquid on an ejection surface 42. The ejection surface 42 is provided at a position on the +Y direction side of the transport roller pair 35. The ejection surface 42 is provided at a position facing the medium support unit 36 ​​across the transport path T. The recording unit 40 is provided inside the housing 13 so as to be movable along the X-axis direction across the width dimension of the medium P.

[0038] The recording unit 40 moves along the X-axis direction and ejects ink, which is an example of liquid, from the nozzles N to perform recording on a first surface S1 of the medium P supported by the medium support unit 36. In addition, in FIG. 3, the first surface S1 of the medium P is the surface facing the nozzles N and is the surface opposite to the second surface S2 supported by the medium support unit 36.

[0039] 1 and 2, the liquid container holding portion 18 is provided inside the housing 13 at a position on the -X direction side of the container portion 15 so that the liquid container LC that contains the ink ejected from the recording portion 40 can be attached and detached. By opening a holder cover 19 provided on the +Y direction side of the liquid container holding portion 18, the liquid container LC can be attached and detached from the liquid container holding portion 18 from the +Y direction. The liquid container holding portion 18 is connected to the recording portion 40 by a supply tube (not shown) so that the ink in the liquid container LC attached to the liquid container holding portion 18 can be supplied to the recording portion 40.

[0040] The maintenance unit 50 performs maintenance on the recording unit 40. As shown in Fig. 2, the maintenance unit 50 is provided inside the housing 13 at a position on the -X direction side of the transport path T and on the -Y direction side of the liquid container holding unit 18. The maintenance unit 50 has a waste liquid receiving unit 52, a waste liquid tank 53, a waste liquid tube 54, a pump 58, and a wiper 59.

[0041] The waste liquid receiving section 52 receives ink discharged as waste liquid from the recording section 40 during maintenance of the recording section 40. The waste liquid receiving section 52 is disposed on the +Z direction side, vertically below the scanning area in which the recording section 40 moves along the X-axis direction. The waste liquid receiving section 52 receives ink discharged as waste liquid from the recording section 40 in either a state in which it is in contact with the ejection surface 42 of the recording section 40 or a state in which it is separated from the ejection surface 42.

[0042] The ink as waste liquid received by the waste liquid receiving unit 52 is collected in the waste liquid tank 53 via the waste liquid tube 54. A pump 58 is provided in the middle of the waste liquid tube 54 to send the waste liquid received by the waste liquid receiving unit 52 toward the waste liquid tank 53. The waste liquid tank 53 is provided at a position between the waste liquid receiving unit 52 and the liquid container holding unit 18 in the Y-axis direction. The wiper 59 wipes the ejection surface 42 of the recording unit 40 to remove foreign matter such as ink and paper powder adhering to the ejection surface 42.

[0043] 2 and 3, the cutting unit 60 is provided at a position on the +Y direction side of the recording unit 40 and the medium support unit 36 ​​so as to be able to cut the medium P recorded by the recording unit 40. The cutting unit 60 is also provided with removal units 81 and 82 that remove paper dust generated when the cutting unit 60 cuts the medium P.

[0044] 2 to 4, the cutting unit 60 has a movable blade 61, a fixed blade 62, and a moving unit 70. The moving unit 70 moves the movable blade 61 in the X-axis direction intersecting with the Y-axis direction. The moving unit 70 has a carriage 71, a carriage guide 72, pulleys 73 and 74, an endless belt 75, a carriage motor 76, and an encoder (not shown). The encoder is a rotary encoder that detects the rotation of the carriage motor 76.

[0045] The carriage 71 is supported by a carriage guide 72 that extends in the X-axis direction across the width dimension of the medium P so as to be movable along the X-axis direction. The carriage 71 is attached to an endless belt 75 that is stretched around pulleys 73 and 74 that are spaced apart in the X-axis direction. The pulley 73 is fixed to the drive shaft of a carriage motor 76. The carriage motor 76 is driven based on a signal detected by a rotary encoder, so that the carriage 71 moves in the +X direction or -X direction along the X-axis direction.

[0046] The carriage 71 is provided with a movable blade 61, removal units 81 and 82, and a contact unit 78. The movable blade 61 is provided on the carriage 71 so as to be able to cut the medium P. As shown in FIGS. 4 to 8, the movable blade 61 is supported by a shaft unit 77 provided on the carriage 71. The shaft unit 77 has a cylindrical shape extending in the Y-axis direction. The movable blade 61 is supported by the shaft unit 77 so as to be able to rotate around the shaft unit 77 as the center of rotation. The movable blade 61 of this embodiment is a so-called round blade, which is a circular blade. As the carriage 71 moves along the X-axis direction, the movable blade 61, removal units 81 and 82, and contact unit 78 move along the X-axis direction.

[0047] The fixed blade 62 is provided on the +Z direction side of the carriage 71. The fixed blade 62 extends in the X direction corresponding to the movement area of ​​the movable blade 61. The fixed blade 62 also extends along the Y direction, and the +Y direction end of the fixed blade 62 contacts the surface of the movable blade 61 on the -Y direction side. The fixed blade 62 is provided with a side wall 62b extending in the +Z direction from the -Y direction end of the fixed blade 62 and a side wall 62c continuing from the side wall 62b. The side wall 62c extends along the Y direction. The side wall 62c supports the paper powder retaining portion 56 provided between the fixed blade 62 and the side wall 62c in the Z direction.

[0048] The side wall 62b extends in the Z-axis direction and connects between the fixed blade 62 and the side wall 62c. As shown in FIG. 3, the side wall 62b is located between the paper dust retaining unit 56 and the recording unit 40 in the Y-axis direction. The side wall 62b is an example of a wall portion WP that separates the paper dust retaining unit 56 and the discharge surface 42 of the recording unit 40 in the Y-axis direction. In addition, the fixed blade 62 and the side walls 62b, 62c cover the paper dust retaining unit 56 in the direction toward the recording unit 40. Therefore, the fixed blade 62 and the side walls 62b, 62c isolate the paper dust retaining unit 56 from the recording unit 40.

[0049] When cutting the medium P, with the medium P positioned above the fixed blade 62, the carriage 71 moves in the -X direction along the X axis direction from a standby position provided outside the +X direction side of the transport path T. As a result, the movable blade 61 moves in the -X direction along the X axis direction while in contact with the fixed blade 62, thereby cutting the medium P. In other words, the movable blade 61 cuts the medium P in cooperation with the fixed blade 62.

[0050] 4 to 8, the removal unit 81 is, for example, a brush and is capable of holding the removed paper powder. As shown in Fig. 6, the removal unit 81 is provided on the carriage 71 so that the tip of the brush can contact the surface in the -Z direction that is the upper surface of the fixed blade 62. Therefore, when the medium P is located between the fixed blade 62 and the removal unit 81, the brush of the removal unit 81 contacts the surface in the -Z direction that is the upper surface of the medium P.

[0051] In addition, in the X-axis direction, the removal unit 81 is located in the +X direction of the cutting position CP where the movable blade 61 cuts the medium P. In this embodiment, the cutting position CP is the position of the -X direction outer edge of the -Y direction surface of the movable blade 61 that contacts the +Y direction end of the upper surface of the fixed blade 62, as shown in Figs. 6, 8 and 9. The X-axis direction is an example of a cutting direction in which the movable blade 61 moves when cutting the medium P. The +X direction is an example of an upstream cutting direction, and the -X direction is an example of a downstream cutting direction.

[0052] 7, the -X side end of removal unit 81 is located in the -Y direction from the +X side end of removal unit 81, and is located in the -Y direction from movable blade 61. The +X side end of removal unit 81 is located in the +Y direction from the -Y side surface of movable blade 61. In other words, the +X side end of removal unit 81 is located in the +Y direction from cutting position CP where medium P is cut.

[0053] 6 to 8, the remover 82 is, for example, a brush and is capable of holding the removed paper powder. The remover 82 is provided at the end of the shaft 77 on the +Y direction side so as to be able to contact the surface of the movable blade 61 on the +Y direction side. The remover 82 is also provided on the shaft 77 so that the tip of the brush can contact the surface of the medium P on the -Z direction side when the medium P is vertically below the remover 82. The shaft 77 is supported by the carriage 71 so as to be rotatable around the axis of the shaft 77 as the center of rotation. A gear 86 is provided at the end of the shaft 77 on the -Y direction side.

[0054] Furthermore, a rack 87 extending along the X-axis direction is provided on the fixed blade 62 at a position outside the +X direction side of the transport path T and at a position where the fixed blade 62 meshes with the gear 86. The gear 86 and the rack 87 form a rotating unit 85 that rotates the removal unit 82 and the movable blade 61 relatively.

[0055] In this embodiment, the position of the carriage 71 is set to a position on the -X side of the standby position when the tooth of the rack 87 located furthest in the -X direction meshes with the gear 86. Also, in this embodiment, when the carriage 71 is in the standby position, the gear 86 meshes with the rack 87. Also, in this embodiment, the position of the movable blade 61 is set to a position on the +X side of the transport path T when the tooth of the rack 87 located furthest in the -X direction meshes with the gear 86.

[0056] For example, assume that after the cutting unit 60 cuts the medium P by moving the carriage 71 in the -X direction from the standby position, the carriage 71 moves in the +X direction from the -X side of the transport path T toward the standby position. In this case, the gear 86 and the rack 87 mesh with each other while the carriage 71 is moving in the +X direction toward the standby position.

[0057] Then, with the gear 86 and rack 87 meshing, the carriage 71 continues to move in the +X direction, causing the shaft portion 77 and the removal portion 82 to rotate around the axis of the shaft portion 77. As a result, the removal portion 82 rotates while in contact with the movable blade 61, and paper dust adhering to the movable blade 61 is removed from the movable blade 61. The paper dust removed from the movable blade 61 is collected and held in the removal portion 82.

[0058] 5 to 7, a static eliminator 88 is provided on the fixed blade 62 at a position outside the +X direction side of the transport path T. The static eliminator 88 is a so-called static elimination brush, and when a brush portion comes into contact with the carriage 71, static elimination is performed on the carriage 71, the movable blade 61 provided on the carriage 71, the shaft portion 77, the removal portions 81 and 82, and the contact portion 78.

[0059] In this embodiment, static electricity generated by friction between members is used to temporarily hold paper powder in the removers 81 and 82. For this reason, for example, while each member constituting the conveying unit 33 in this embodiment is grounded, the removers 81 and 82, the movable blade 61, the fixed blade 62, etc. of the cutting unit 60 are not grounded.

[0060] In this embodiment, the medium P is paper such as printing paper, and the material of the brush serving as the movable blade 61 and the remover 81 is on the negative side of the paper in the triboelectric series. The material of the brush serving as the remover 82 is on the negative side of the material of the movable blade 61 in the triboelectric series. For example, the movable blade 61 is made of a steel material such as tool steel or stainless steel. In this case, the material of the brush serving as the removers 81 and 82 is, for example, polypropylene, polyester, polyethylene, polytetrafluoroethylene, or the like. Incidentally, the fixed blade 62 is made of a steel material such as tool steel or stainless steel, like the movable blade 61.

[0061] In addition, the carriage 71, the movable blade 61 provided on the carriage 71, the shaft portion 77, the removal portions 81 and 82, and the contact portion 78 are conductive. For example, the carriage 71 and the shaft portion 77 may be formed by casting using a metal material, or may be formed from a conductive resin material. In addition, for example, the carriage 71, the shaft portion 77, the removal portions 81 and 82, and the contact portion 78 may be formed from a composite material that is made conductive by adding an inorganic conductor such as carbon fiber to a resin material, or by forming a thin conductive film on the surface. At least a part of the above configuration does not have to be conductive.

[0062] For example, in the cutting operation of medium P, assume that carriage 71 moves in the X-axis direction with movable blade 61 and removal units 81, 82 in contact with medium P. In this case, paper dust generated by cutting of medium P by cutting unit 60 is positively charged, and movable blade 61 and removal unit 81 are negatively charged. For this reason, paper dust generated by cutting of medium P by cutting unit 60 is attracted to movable blade 61 or removal units 81, 82 and temporarily held there.

[0063] Furthermore, paper dust adhering to the surface of the movable blade 61 in the +Y direction is removed by and held in the removal unit 82. When the brush portion of the charge removing unit 88 comes into contact with the carriage 71, the carriage 71, the movable blade 61 provided on the carriage 71, the shaft unit 77, the removal units 81 and 82, and the contact unit 78 are neutralized. This reduces, for example, the force with which the movable blade 61 or the removal unit 82 holds the paper dust.

[0064] The brush portion of the static eliminator 88 disposed on the fixed blade 62 contacts the carriage 71 over a predetermined section in which the carriage 71 moves along the X-axis with the gear 86 and the rack 87 meshing with each other. This causes the remover 82 to rotate relative to the movable blade 61 when the movable blade 61 is being neutralized by the static eliminator 88.

[0065] In other words, while the static eliminator 88 is eliminating static electricity from the movable blade 61, the rotating unit 85 relatively rotates the remover 82 and the movable blade 61. This causes the remover 82 to remove the paper dust from the movable blade 61, whose retention force for retaining the paper dust has decreased. The paper dust temporarily retained by the remover 82 then falls from the remover 82 in the +Z direction and is collected in the paper dust retaining unit 56.

[0066] 5 to 9, the abutment portion 78 is provided on the carriage 71 so as to be able to push a portion of the medium P that is on the +X direction side and on the +Y direction side of the movable blade 61 in the +Z direction. The abutment portion 78 has a thin plate shape extending in the +Z direction from the carriage 71. The abutment portion 78 in this embodiment is formed integrally with the carriage 71. A tip portion 78c of the abutment portion 78 that pushes the aforementioned portion of the medium P in the +Z direction has a semicircular shape when viewed from a direction along the Y axis direction.

[0067] 6 and 8, the +Z end of tip 78c is located in the +Z direction from the -Z direction surface of fixed blade 62 in the Z axis direction. In this embodiment, the +Z end of tip 78c is located in the +Z direction from the +Z direction end of movable blade 61 in the Z axis direction. Also, in this embodiment, as shown in Figs. 6 and 7, the +Z end of tip 78c is located in the +X direction from the +X direction end of removal portion 81 in the X axis direction.

[0068] When the carriage 71 moves in the -X direction from the standby position to cut the medium P by the cutting unit 60, the contact unit 78 pushes in the +Z direction a portion of the medium P that is on the +X direction side and on the +Y direction side of the movable blade 61. As a result, as shown in Fig. 9, a gap G is formed between a portion DP of the medium P that is on the -Y direction side of the movable blade 61 and a portion UP of the medium P that is on the +Y direction side of the movable blade 61, which are separated by being cut.

[0069] 2 to 8, the paper dust holding unit 56 is located on the +Z direction side of the cutting unit 60, and collects and holds paper dust generated when the medium P is cut by the cutting unit 60. The paper dust holding unit 56 is in the shape of a bottomed box having an opening 56c that opens toward the -Z direction so that paper dust can be collected. The opening 56c extends in the X-axis direction corresponding to the movement area of ​​the movable blade 61 and the removers 81 and 82 provided on the carriage 71.

[0070] The opening 56c of the paper powder retaining portion 56 supported by the side wall 62c is disposed in a position in the Y axis direction that is vertically below the end of the fixed blade 62 on the +Y direction side and the movable blade 61. In other words, the paper powder retaining portion 56 and the opening 56c of the paper powder retaining portion 56 are positioned vertically below the area between the remover 81 and the contact portion 78 in the Y axis direction.

[0071] 2 and 3, the discharge unit 45 transports the medium P recorded by the recording unit 40 and the medium P cut by the cutting unit 60 along the transport path T toward the mounting unit 16 located on the +Y direction side of the recording unit 40. The discharge unit 45 has a first discharge roller pair 46 and a second discharge roller pair 47.

[0072] The first discharge roller pair 46 is provided at a position on the +Y direction side of the recording unit 40 and the medium support unit 36, and on the -Y direction side of the cutting unit 60. The first discharge roller pair 46 rotates with the medium P sandwiched between them, thereby transporting the medium P along the transport path T toward the cutting unit 60 and the mounting unit 16, which are located on the +Y direction side of the first discharge roller pair 46.

[0073] 3, the second discharge roller pair 47 is provided at a position on the +Y direction side of the cutting unit 60. The second discharge roller pair 47 is also provided at a position on the -Y direction side of the opening 17 that opens into the front surface of the housing 13. As the first discharge roller pair 46 and the second discharge roller pair 47 which sandwich the medium P therebetween rotate, the discharge unit 45 sends out the medium P in the +Y direction.

[0074] The second discharge roller pair 47 transports the medium P cut by the cutting unit 60. Of the paper dust generated by cutting the medium P, the paper dust that is not removed by the removal units 81 and 82 may adhere to the surface of the cut medium P on the -Z direction side.

[0075] Each member constituting the discharge unit 45 of this embodiment is grounded, similar to the members constituting the transport unit 33. Furthermore, the first discharge roller pair 46 and the second discharge roller pair 47 are each composed of a pair of rollers 48, 49. The roller 49 that contacts the surface of the medium P on the -Z direction side is composed of a toothed roller made of a steel material such as stainless steel. The roller 48 that contacts the surface of the medium P on the +Z direction side is composed of a cylindrical roller made of an elastic material such as rubber.

[0076] In this case, roller 49 in contact with the surface of medium P on the -Z direction side has higher conductivity and is therefore more easily grounded and less likely to become charged than roller 48 in contact with the surface of medium P on the +Z direction side. For this reason, particularly in the second discharge roller pair 47, it is easier to prevent paper dust adhering to the surface of medium P on the -Z direction side from adhering to roller 49. Also, roller 49 in contact with the surface of medium P on the -Z direction side is configured as a toothed roller, and therefore can prevent ink from being transferred from the surface of medium P on the -Z direction side that was previously recorded on.

[0077] The mounting section 16 receives the medium P transported by the discharge section 45. As shown in FIG. 3, the mounting section 16 in this embodiment is attached to the -Z direction side of the storage section 15. By being attached to the storage section 15, the mounting section 16 covers the opening on the -Z direction side of the storage section 15. By placing the storage section 15 at a supply position inside the housing 13 via the opening 17, the mounting section 16 is placed at a mounting position (see FIG. 3) where the medium P is placed on the mounting section 16. In other words, the mounting section 16 is integral with the storage section 15 and is detachably provided inside the housing 13.

[0078] The mounting portion 16 in the mounting position is located on the +Z direction side vertically below the operation portion 14. Furthermore, the mounting portion 16 in the mounting position is located between the operation portion 14 and the storage portion 15 in the Z-axis direction. Furthermore, the mounting portion 16 in the mounting position is located on the +Z direction side below the cutting portion 60 and the removal portions 81, 82. In other words, the mounting portion 16 in the mounting position overlaps with the movement areas of the cutting portion 60 and the removal portions 81, 82 when viewed from vertically above on the -Z direction side.

[0079] In the placement unit 16, the support portion 16m that receives the medium P may be a plane extending in the X-axis and Y-axis directions along the XY plane, or may be a plurality of protrusions extending in the Y-axis direction and spaced apart in the X-axis direction. 2 and 3, for example, the +Y side of the support portion 16m from the center may be configured with a plane extending in the X-axis and Y-axis directions, and the -Y side of the center may be configured with a plurality of protrusions extending in the Y-axis direction.

[0080] In this case, recesses 16r are formed in a portion of support portion 16m that is configured with multiple protrusions that extend in the Y-axis direction and are spaced apart in the X-axis direction. Recesses 16r are recesses that are recessed in the +Z direction from the multiple protrusions that receive medium P. Recesses 16r are located vertically below the movement area of ​​movable blade 61, fixed blade 62, movement areas of removal portions 81 and 82, paper dust holding portion 56, and second discharge roller pair 47. This allows the placement portion 16 to receive paper dust that falls outside of paper dust holding portion 56, among the paper dust generated by cutting medium P, in recesses 16r.

[0081] The control unit 90 comprehensively controls the driving of each mechanism in the recording device 11 and controls various operations executed by the recording device 11. The control unit 90 may be configured as a circuit including one or more processors that execute various processes according to a computer program, one or more hardware circuits that execute at least a part of the various processes, or a combination thereof. The hardware circuit is, for example, an application specific integrated circuit. The processor includes a CPU and memories such as RAM and ROM, and the memory stores program codes or instructions configured to cause the CPU to execute processes.

[0082] For example, the control unit 90 controls the feeding unit 31, the transport unit 33, the recording unit 40, and the discharge unit 45 to transport the medium P, on which recording has been performed by the recording unit 40, toward the mounting unit 16. Also, for example, assume that double-sided recording is performed by recording on both the first side S1 and the second side S2 of the medium P. In this case, the control unit 90 controls the transport unit 33 and the discharge unit 45 to transport the medium P, on which recording has been performed on the first side S1, to a position in the +Y direction of the switching unit 38.

[0083] Then, the control unit 90 controls the second discharge roller pair 47 and the switching units 38, 39 to transport the medium P again to the transport path T via the reversal path R. Then, the control unit 90 controls the transport roller pair 35 to transport the medium P toward the medium support unit 36. As a result, the medium P transported along the transport path T is supported by the medium support unit 36 ​​with the second surface S2 facing the nozzle N. Then, the control unit 90 controls the recording unit 40 to perform recording on the second surface S2 of the medium P supported by the medium support unit 36. As a result, double-sided recording is performed on the medium P.

[0084] The control unit 90 also controls the moving unit 70 of the cutting unit 60 to cut the medium P. The control unit 90 also controls the moving unit 70 of the cutting unit 60 to cause the removal units 81, 82 to remove paper dust generated when the cutting unit 60 cuts the medium P. The control unit 90 also controls the reading unit 21 to read an image of the original document, etc. The control unit 90 also controls the operation unit 14 to display a message on the display unit of the operation unit 14, thereby notifying the user of the status of the recording device 11.

[0085] As described above, according to the recording device 11 of the first embodiment, the following effects can be obtained.

[0086] The recording device 11 includes a recording unit 40 that records on the medium P transported from the -Y direction to the +Y direction in the Y-axis direction, and a cutting unit 60 that can cut the medium P recorded by the recording unit 40. The recording device 11 also includes a discharge unit 45 that transports the medium P recorded by the recording unit 40 and the medium P cut by the cutting unit 60 in the +Y direction. The recording device 11 also includes removal units 81 and 82 that remove paper dust generated when the medium P is cut by the cutting unit 60. By removing the paper dust with the removal units 81 and 82, it is possible to reduce the risk that the paper dust generated when the medium P is cut will interfere with the operation of the recording device 11. Note that the recording device 11 only needs to include at least one of the removal units 81 and 82.

[0087] The cutting unit 60 has a movable blade 61 that cuts the medium P, and a moving unit 70 that moves the movable blade 61 in the X-axis direction that intersects with the Y-axis direction. The removal units 81, 82 are provided so as to be able to come into contact with the medium P, and are moved together with the movable blade 61 by the moving unit 70. Since the removal units 81, 82 move together with the movable blade 61, paper dust generated by cutting the medium P with the movable blade 61 can be quickly removed. Since the removal units 81, 82 are moved by the moving unit 70 of the cutting unit 60, paper dust can be removed across the entire width of the medium P with a simple configuration.

[0088] In the X-axis direction, the removal unit 81 is located in the +X direction from the cutting position CP where the movable blade 61 cuts the medium P. As a result, when the medium P is cut by the cutting unit 60, the removal unit 81 is located upstream in the cutting direction from the cutting position CP. Therefore, paper dust generated when the medium P is cut is more effectively removed.

[0089] The end of the removal unit 81 on the -X direction side is located in the -Y direction from the end of the removal unit 81 on the +X direction side, and is located in the -Y direction from the movable blade 61. With this, by moving the removal unit 81 in the -X direction, the removal unit 81 can remove paper dust in an area of ​​the medium P on the -Y direction side from the movable blade 61, and gradually move the paper dust in the +Y direction away from the recording unit 40. This can suppress malfunctions of the recording device 11, such as a decrease in recording accuracy by the recording unit 40 due to paper dust adhering to the discharge surface 42 in the recording unit 40 or paper dust entering the nozzles N.

[0090] The end of the removal unit 81 on the +X direction side is located in the +Y direction from the movable blade 61. With this, by moving the removal unit 81, it is possible to move the paper dust in the +Y direction, which is downstream in the transport direction from the movable blade 61. Therefore, it is possible to further prevent the paper dust from adhering to the recording unit 40.

[0091] The recording device 11 further includes a paper dust holding unit 56 that holds the paper dust removed by the removal units 81 and 82. The moving unit 70 also has a contact unit 78 that presses down a portion of the medium P that is located in the +Y direction from the movable blade 61. The paper dust holding unit 56 is located vertically below the area between the removal unit 81 and the contact unit 78 in the Y-axis direction. As a result, a gap G is formed by the contact unit 78 between the portion UP of the medium P and the portion DP of the medium P that are separated by being cut. This makes it easier for the paper dust removed by the removal unit 81 to fall from the gap G. The paper dust that falls from the gap G is collected in the paper dust holding unit 56.

[0092] The cutting unit 60 has a fixed blade 62 that cooperates with the movable blade 61 to cut the medium P, the fixed blade 62 extends in the X-axis direction, and the removal unit 81 is capable of contacting the fixed blade 62. With this, the removal unit 81 comes into contact with the fixed blade 62 directly or via the medium P, thereby making it possible to more reliably remove paper dust.

[0093] The cutting unit 60 has a movable blade 61 that cuts the medium P, a shaft portion 77 that supports the movable blade 61, and a moving portion 70 that moves the movable blade 61 in the X-axis direction that intersects with the Y-axis direction. The removal portion 82 is provided on the shaft portion 77 and is capable of contacting the movable blade 61. The removal portion 82 and the movable blade 61 are capable of rotating relatively to each other. This allows the removal portion 82 to remove paper dust adhering to the movable blade 61. This allows the sharpness of the movable blade 61 to be maintained, and the cutting accuracy of the movable blade 61 to be maintained. Furthermore, maintaining the sharpness of the movable blade 61 also leads to suppressing an increase in the amount of paper dust generated by cutting the medium P.

[0094] The removal unit 82 is capable of contacting the surface of the movable blade 61 on the +Y direction side. This allows the removal unit 82 to remove paper dust adhering to the surface of the movable blade 61 on the +Y direction side opposite to the -Y direction side on which the recording unit 40 is located.

[0095] The removing unit 82 holds the removed paper dust, which can reduce the risk of the removed paper dust adhering to the recording unit 40.

[0096] The recording device 11 further includes a rotating unit 85 that relatively rotates the removing unit 82 and the movable blade 61. Since the removing unit 82 rotates relatively to the movable blade 61, the paper dust adhering to the movable blade 61 can be effectively removed.

[0097] The recording device 11 further includes a static eliminator 88 that eliminates static electricity from the movable blade 61, and while the static eliminator 88 is eliminating static electricity from the movable blade 61, the rotating unit 85 relatively rotates the removal unit 82 and the movable blade 61. With this, the removal unit 82 and the movable blade 61 are relatively rotated while the movable blade 61 is being eliminated, so that paper powder is easily removed from the movable blade 61.

[0098] The recording device 11 further includes a housing 13 that houses the recording unit 40 and the cutting unit 60, and a storage unit 15 that can store a medium P on which the recording unit 40 is recorded, the storage unit 15 being detachable from inside the housing 13. The removal units 81, 82 overlap with the storage unit 15 when viewed vertically from above. With this, even if the paper dust removed by the removal units 81, 82 falls, it falls in the direction toward the storage unit 15. Therefore, by removing the storage unit 15 from the housing 13, the paper dust can be removed from inside the housing 13.

[0099] The recording device 11 includes a housing 13 that houses the recording unit 40 and the cutting unit 60, and a storage unit 15 that can store the medium P recorded by the recording unit 40. The recording device 11 further includes a placement unit 16 that is provided in the -Z direction of the storage unit 15 and on which the medium P recorded by the recording unit 40 is placed. The storage unit 15 and the placement unit 16 are detachable as a unit in the housing 13, and the removal units 81 and 82 overlap with the placement unit 16 when viewed vertically from above. With this, even if the paper dust removed by the removal units 81 and 82 falls, it falls in the direction toward the placement unit 16. Therefore, by removing the storage unit 15 from the housing 13, the paper dust collected in the placement unit 16 can be removed from inside the housing 13.

[0100] The recording device 11 is provided with a paper dust holding unit 56 that is located in the +Z direction of the cutting unit 60 and holds paper dust generated when the medium P is cut by the cutting unit 60. The recording device 11 further includes a wall unit WP that separates the paper dust holding unit 56 and the recording unit 40 in the Y-axis direction. This can reduce the risk of paper dust held by the paper dust holding unit 56 scattering and adhering to the recording unit 40, for example.

[0101] The recording device 11 includes a recording unit 40 that records on the medium P transported from the -Y direction to the +Y direction in the Y-axis direction, and a cutting unit 60 that can cut the medium P recorded by the recording unit 40. The recording device 11 also includes a discharge unit 45 that transports the medium P recorded by the recording unit 40 and the medium P cut by the cutting unit 60 in the +Y direction. The recording device 11 also includes a paper dust holding unit 56 that is located in the +Z direction of the cutting unit 60 and holds paper dust generated when the medium P is cut by the cutting unit 60. With this, by collecting paper dust in the paper dust holding unit 56, it is possible to reduce the risk that paper dust in the housing 13 will interfere with the operation of the recording device 11. In addition, in such a configuration, the recording device 11 does not need to include the removal units 81 and 82.

[0102] The recording device 11 further includes a wall portion WP that separates the paper dust retaining portion 56 and the recording portion 40 in the Y-axis direction. With this, after paper dust is collected in the paper dust retaining portion 56, the recording portion 40 is located on the -Y direction side of the wall portion WP, and the paper dust retaining portion 56 is located on the +Y direction side of the wall portion WP, thereby reducing the risk of paper dust adhering to the recording portion 40.

[0103] The recording device 11 includes a waste liquid collecting unit 55 that collects, as waste liquid, ink ejected from the recording unit 40, which performs recording by ejecting ink onto the medium P, outside the medium P. The recording device 11 also includes an inflow unit 57 that causes the waste liquid collected in the waste liquid collecting unit 55 to flow into the paper dust holding unit 56. By causing the waste liquid to flow into the paper dust holding unit 56, it is possible to prevent paper dust from scattering from the paper dust holding unit 56 without adding a new component.

[0104] The cutting unit 60 has a movable blade 61 that cuts the medium P, and a fixed blade 62 that cooperates with the movable blade 61 to cut the medium P. The fixed blade 62 extends in the X-axis direction intersecting with the Y-axis direction, and the paper dust holding unit 56 is supported by the fixed blade 62. This improves the positional accuracy of the paper dust holding unit 56 with respect to the cutting unit 60. This allows the paper dust holding unit 56 to more reliably collect paper dust.

[0105] The recording device 11 according to the above embodiment of the present disclosure is basically configured as described above, but it is of course possible to modify or omit a part of the configuration without departing from the scope of the present disclosure. In addition, the above embodiment and other embodiments described below can be combined with each other within a technically compatible range. Other embodiments will be described below.

[0106] In the above embodiment, the cutting unit 60 does not have to include the fixed blade 62. In addition, the movable blade 61 does not have to be a round blade. In this case, the movable blade 61 may be a flat blade having a pointed portion.

[0107] In the above embodiment, the cutting unit 60 may cut the medium P by moving the carriage 71 equipped with the movable blade 61 in the +X direction. In this case, the standby position of the carriage 71 is disposed at a position outside the -X direction side of the transport path T. Also, in this case, the carriage motor 76 may be provided at a position on the +X direction side of the transport path T. Also, in this case, the removal unit 81 is located in the -X direction from the cutting position CP where the movable blade 61 cuts the medium P. Also, in this case, the end of the removal unit 81 on the +X direction side is located in the -Y direction from the end of the removal unit 81 on the -X direction side, and is located in the -Y direction from the movable blade 61. Also, in this case, the end of the removal unit 81 on the -X direction side is located in the +Y direction from the surface of the movable blade 61 on the -Y direction side.

[0108] In the above embodiment, the cutting unit 60 may cut the medium P by the carriage 71 equipped with the movable blade 61 moving back and forth in the -X direction and the +X direction. In this case, the removal unit 81 may be disposed on either the +X side or the -X side of the cutting position CP where the movable blade 61 cuts the medium P. Alternatively, in this case, the removal unit 81 may be disposed on both the +X side and the -X side of the cutting position CP.

[0109] In the above embodiment, the control unit 90 may control the moving unit 70 of the cutting unit 60 to repeatedly bring the brush portion of the static electricity removing unit 88 into contact with the carriage 71. For example, the control unit 90 may repeatedly bring the brush portion of the static electricity removing unit 88 into contact with and away from the carriage 71 by moving the carriage 71 back and forth in the X-axis direction in a region that is outside the transport path T in the X-axis direction. In this way, the control unit 90 may promote static electricity removal from the carriage 71, the movable blade 61, the shaft portion 77, the removal units 81 and 82, and the contact portion 78 provided on the carriage 71.

[0110] In the above embodiment, the paper powder retaining portion 56 does not have to be provided across the area in the Y axis direction between the -Y direction end of the remover 81 and the abutting portion 78. For example, the paper powder retaining portion 56 may be provided at a position at least partially overlapping with the area in the Y axis direction between the -Y direction end of the remover 81 and the abutting portion 78 when viewed vertically from above.

[0111] In the above embodiment, the opening 56c of the paper powder retaining unit 56 does not have to extend in the X-axis direction corresponding to the movement area of ​​the movable blade 61 and the removers 81, 82 provided on the carriage 71. For example, the opening 56c may be provided corresponding to a section where the brush portion of the static electricity removing unit 88 is in contact with the carriage 71, within the movement area of ​​the movable blade 61 and the removers 81, 82 in the X-axis direction.

[0112] In the above embodiment, the recording device 11 does not necessarily have to include the paper dust retaining unit 56 .

[0113] In the above embodiment, the movable blade 61 may be fixed so as not to rotate with respect to the shaft portion 77. In this case, the removal portion 82 may be provided on the shaft portion 77 so as to be rotatable around the shaft portion 77 as a rotation center, so that the movable blade 61 and the removal portion 82 may rotate relatively to each other.

[0114] In the above embodiment, in addition to the shaft portion 77 and the removal portion 82 rotating around the shaft portion 77 as the center of rotation, the movable blade 61 may rotate relative to the shaft portion 77, causing the movable blade 61 and the removal portion 82 to rotate relative to each other.

[0115] In the above embodiment, the rotating unit 85 does not have to be configured by the gear 86 and the rack 87. For example, the recording device 11 may include, as the rotating unit 85, a drive mechanism and a drive motor that rotate the movable blade 61 separately from the shaft unit 77. In this case, the control unit 90 controls the driving of the drive motor. As a result, the control unit 90 may rotate the movable blade 61, for example, while the carriage 71 is moving across the movement area of ​​the carriage 71 in the X-axis direction. Also, for example, the control unit 90 may rotate the movable blade 61 when the carriage 71 is in the standby position.

[0116] In the above embodiment, the movable blade 61 may rotate due to sliding against the fixed blade 62 and the medium P as the carriage 71 moves in the X-axis direction, thereby causing the movable blade 61 and the remover 82 to rotate relatively. In this case, the rotating unit 85 may not be provided.

[0117] In the above embodiment, the brush portion of the static eliminator 88 may be disposed so as to extend in the X-axis direction along the movement area in which the carriage 71 moves. This allows the brush portion of the static eliminator 88 to be in constant contact with the carriage 71 in the movement area in which the carriage 71 moves along the X-axis.

[0118] In the above embodiment, the recording device 11 may include a charging device that charges the movable blade 61 of the cutting unit 60. This allows more paper dust generated when the medium P is cut by the cutting unit 60 to adhere to the movable blade 61, and the paper dust adhering to the movable blade 61 may be removed by the removal unit 82.

[0119] In the above embodiment, the removal units 81 and 82 may not temporarily hold paper powder by utilizing static electricity generated by friction between members. In this case, the cutting unit 60 may be grounded. Also, in this case, the material of the brush serving as the removal unit 81 may be one that is on the positive side of the paper in the electrification series. Also, in this case, the material of the brush serving as the removal unit 82 may be one that is on the positive side of the material of the movable blade 61 in the electrification series.

[0120] In the above embodiment, the removal units 81 and 82 may not temporarily hold paper dust by utilizing static electricity generated by friction between members.
