[0008] 1. Embodiment 1 The schematic configuration of a recording device 100 according to the first embodiment will be described.
[0009] The recording device 100 is an inkjet printer capable of recording on a medium P (see FIG. 3). The recording device 100 is not limited to an inkjet printer, and may be any device capable of recording on a medium P.
[0010] In the following explanation, as shown in each figure, three mutually orthogonal axes are referred to as the X-axis, Y-axis, and Z-axis. On each axis, the direction indicated by the arrow is the + direction, and the opposite direction is the - direction. The Z-axis direction corresponds to the vertical direction, i.e. the direction in which gravity acts, the +Z direction indicates the vertical upward direction, and the -Z direction indicates the vertical downward direction. The X-axis and Y-axis directions correspond to the horizontal direction. The +Y direction indicates the front direction of the device, and the -Y direction indicates the rear direction of the device. The +X direction indicates the right direction when facing the front of the device, and the -X direction indicates the left direction when facing the front of the device.
[0011] As shown in FIGS. 1 to 3, the recording device 100 includes a recording unit 10, a conveying unit 20, a cutting unit 30, a medium storage unit 101, a paper discharge tray 102, an operation unit 103, and a control unit 104.
[0012] The control unit 104 includes a CPU, a flash ROM, and a RAM. The CPU performs various arithmetic processing according to programs stored in the flash ROM, and controls the overall operation of the recording device 100. The flash ROM, which is an example of a storage means, is a non-volatile memory that can be read and written. Various information is temporarily stored in the RAM, which is an example of a storage means.
[0013] As shown in Fig. 1, the operation unit 103 is provided on the front surface of the device, which is the surface in the +Y direction. More specifically, the operation unit 103 is provided in the center of the X-axis direction on the front surface of the device. The operation unit 103 has a touch panel display unit, operation buttons, and the like. By operating the operation unit 103, the user can set and register information related to recording, and information related to the size and type of the medium P, and the like.
[0014] The medium storage unit 101 is provided in the -Z direction of the operation unit 103. The medium storage unit 101 is capable of storing a plurality of media P. The medium storage unit 101 is a so-called tray having a bottomed box shape that is open on the +Z direction side so that the medium P can be placed thereon. The medium storage unit 101 is provided in a detachable manner on the device.
[0015] The paper discharge tray 102 is provided on the −Z direction of the operation unit 103 and on the +Z direction of the medium storage unit 101. The medium P transported by the transport unit 20 is discharged to the paper discharge tray 102.
[0016] 2 and 3, the recording unit 10 has a liquid ejection head (not shown) that ejects liquid. The recording unit 10 is movable in the X-axis direction by a movement mechanism (not shown). The recording unit 10 performs recording on the medium P by ejecting liquid while moving in the X-axis direction.
[0017] 3, the transport unit 20 has a feed roller 21, a transport roller pair 22, a first discharge roller pair 23, and a second discharge roller pair 24. The transport unit 20 transports the medium P along the transport path T and discharges it onto the discharge tray 102. In the following description, the direction in which the medium P is sent along the transport path T is also referred to as the "downstream", and the opposite direction is also referred to as the "upstream".
[0018] The paper feed roller 21 rotates while in contact with the medium P stored in the medium storage unit 101, thereby sending the uppermost medium P to the transport path T. The paper feed roller 21 sends out the medium P stored in the medium storage unit 101 to the transport path T one sheet at a time.
[0019] The transport roller pair 22 is provided downstream of the paper feed roller 21 on the transport path T. The transport roller pair 22 transports the medium P in the +Y direction toward a position facing the recording unit 10. The transported medium P is recorded by the recording unit 10.
[0020] The first discharge roller pair 23 as the first roller pair is provided downstream of the recording unit 10 and upstream of the cutting unit 30 in the transport direction in which the medium P is transported. The first discharge roller pair 23 transports the medium P recorded by the recording unit 10 in the +Y direction toward the cutting unit 30.
[0021] The second discharge roller pair 24 serving as the second roller pair is provided downstream of the cutting unit 30 in the transport direction in which the medium P is transported. The second discharge roller pair 24 transports the medium P cut by the cutting unit 30 in the +Y direction. The medium P transported by the second discharge roller pair 24 is discharged onto the paper output tray 102. The +Y direction in which the medium P is transported in the cutting unit 30 is also referred to as the transport direction A. In other words, the transport unit 20 transports the medium P in the cutting unit 30 in the transport direction A.
[0022] 2 to 4, the cutting unit 30 has a carriage 31, pulleys 32 and 33, an endless belt 34, a carriage motor 35, a guide rail 36, a rotary encoder 37, a movable blade 38, and a fixed blade 39. The cutting unit 30 is provided downstream of the recording unit 10 on the transport path T. The cutting unit 30 is capable of cutting the medium P recorded by the recording unit 10.
[0023] The carriage 31 is movable along a guide rail 36 that extends in the X-axis direction across the width dimension of the medium P. In other words, the carriage 31 is movable in the X-axis direction. The carriage 31 is attached to an endless belt 34 that is stretched around two pulleys 32 and 33 that are spaced apart in the X-axis direction. One of the pulleys, 33, is fixed to the drive shaft of a carriage motor 35. When the carriage motor 35 is driven based on a signal detected by a rotary encoder 37, the carriage 31 moves in the +X direction or -X direction along the X-axis direction.
[0024] The movable blade 38, which is a cutting blade, is held by the carriage 31. Therefore, the movable blade 38 cuts the medium P recorded by the recording unit 10 by moving along the X-axis direction together with the carriage 31. As shown in FIGS. 2 and 4, the movement direction of the movable blade 38 toward the +X direction is referred to as the cutting direction B. The cutting direction B is a direction that intersects with the transport direction A. The movable blade 38 has a contact portion S (see FIG. 5) that comes into contact with the medium P, and cuts the medium P at the contact portion S. The movable blade 38 in this embodiment is a so-called round blade, which is a circular blade.
[0025] The fixed blade 39 is provided in the -Z direction of the carriage 31, upstream of the movable blade 38 in the transport direction A. The fixed blade 39 extends in the X-axis direction corresponding to the movement range of the movable blade 38. When cutting the medium P, with the medium P positioned on the fixed blade 39, the movable blade 38 moves in cutting direction B from a position outside the medium P in the X-axis direction along the fixed blade 39 so as to cross the medium P. In this way, the movable blade 38 moves in cutting direction B while in contact with the fixed blade 39, thereby cutting the medium P. In other words, the medium P is cut by the movable blade 38 and the fixed blade 39.
[0026] Furthermore, the medium P is cut by the cutting section 30 in a state in which the upstream side in the transport direction A is nipped by the first discharge roller pair 23 and the downstream side in the transport direction A is nipped by the second discharge roller pair 24.
[0027] 5, the recording device 100 includes a pressing unit 40 that presses the surface of the medium P in the -Z direction when the cutting unit 30 cuts the medium P. The pressing unit 40 is provided on the carriage 31. Therefore, the pressing unit 40 is provided between the first discharge roller pair 23 and the second discharge roller pair 24 in the transport direction A. Furthermore, as the movable blade 38 moves in the cutting direction B, the pressing unit 40 also moves in the cutting direction B.
[0028] The pressing unit 40 has a roller 41, a rotating shaft 42, a roller support unit 43, and an urging member 44. The roller 41 is capable of contacting the surface of the medium P and is capable of rotating around the rotating shaft 42 along the conveying direction A. Therefore, when the movable blade 38 and the pressing unit 40 move in the cutting direction B, the roller 41 presses the surface of the medium P while rotating.
[0029] The roller support part 43 holds the rotating shaft 42 and supports the roller 41 via the rotating shaft 42. The biasing member 44 biases the roller 41 in the -Z direction toward the medium P by biasing the roller support part 43 downward. The biasing member 44 is, for example, a spring having elasticity.
[0030] As shown in FIG. 6, roller 41 is provided upstream of movable blade 38 in transport direction A. Therefore, roller 41 presses the surface of medium P located on fixed blade 39 when cutting unit 30 cuts medium P. Also, as shown in FIG. 5, roller 41 presses a position downstream of movable blade 38 in cutting direction B. However, roller 41 may be provided so as to press a range extending from a position overlapping contact portion S as viewed from transport direction A to a position downstream of movable blade 38 in cutting direction B. Also, roller 41 may be provided so as to locally press a position overlapping contact portion S as viewed from transport direction A.
[0031] As shown in FIG. 7, the pressing unit 40 may have a roller 45 and a subframe 46. The rotation shaft, roller support, and biasing member related to the roller 45 are the same as those of the roller 41, and therefore will not be described. The roller 45 and the subframe 46 are provided downstream of the movable blade 38 in the conveying direction A. When the cutting unit 30 cuts the medium P, the roller 45 presses the surface of the medium P located on the subframe 46 in the -Z direction. Similarly to the roller 41, the roller 45 may be provided so as to press a position downstream of the movable blade 38 in the cutting direction B, or may be provided so as to press a position overlapping with the contact portion S as viewed from the conveying direction A. Note that the configuration may include only the roller 41, or may include only the roller 45. The configuration may include both the roller 41 and the roller 45.
[0032] As described above, the recording device 100 according to the first embodiment can provide the following advantages.
[0033] The recording device 100 includes a recording unit 10 that records on the medium P, a transport unit 20 that transports the medium P in a transport direction A, a cutting unit 30 that cuts the medium P, and a pressing unit 40 that presses the surface of the medium P when the cutting unit 30 cuts the medium P. This allows the cutting unit 30 to cut the medium P in a state where the surface is pressed by the pressing unit 40. Therefore, the medium P can be cut while suppressing floating of the medium P. Therefore, poor cutting of the medium P can be prevented.
[0034] The medium P is cut by the cutting unit 30 with the upstream side in the transport direction A being nipped by the first discharge roller pair 23 and the downstream side in the transport direction A being nipped by the second discharge roller pair 24, and the pressing unit 40 is provided between the first discharge roller pair 23 and the second discharge roller pair 24 in the transport direction A. Since the pressing unit 40 is provided between the first discharge roller pair 23 and the second discharge roller pair 24 in the transport direction A, the medium P can be cut by the cutting unit 30 while effectively suppressing floating of the medium P in the state nipped by the first discharge roller pair 23 and the second discharge roller pair 24. Therefore, poor cutting of the medium P can be prevented.
[0035] The pressing unit 40 is provided on the carriage 31. With this, as the carriage 31 moves in the cutting direction B, the pressing unit 40 also moves in the cutting direction B, so that floating of the medium P can be suppressed while the cutting unit 30 cuts the medium P. In addition, since the movable blade 38 and the pressing unit 40 are provided on the carriage 31, the pressing unit 40 is positioned in the vicinity of the movable blade 38, so that the medium P can be effectively pressed down. Therefore, poor cutting of the medium P can be prevented.
[0036] The pressing unit 40 has a roller 41 that rotates around a rotation axis 42 along the transport direction A. With this, when the pressing unit 40 moves in the cutting direction B, the roller 41 presses the surface of the medium P while rotating, so that it is possible to reduce friction when the roller 41 presses the medium P. Therefore, it is possible to efficiently suppress floating of the medium P while reducing the risk that the pressing unit 40 will damage the medium P.
[0037] The pressing unit 40 has a biasing member 44 that biases the roller 41 toward the surface of the medium P. With this, the medium P can be effectively pressed by biasing the roller 41 with the biasing member 44. Furthermore, even if the thickness of the medium P varies depending on the type of medium P, the medium P can be effectively pressed. Therefore, floating of the medium P can be suppressed.
[0038] The roller 41 presses against a position downstream of the movable blade 38 in the cutting direction B. This allows the pressing portion 40 to press down the medium P before the movable blade 38 cuts the medium P, effectively preventing the medium P from floating when the medium P is cut. This makes it possible to prevent poor cutting of the medium P.
[0039] 2. Embodiment 2 Next, a schematic configuration of a recording device 100 according to a second embodiment will be described. The same components as those in the first embodiment will be denoted by the same reference numerals, and duplicated descriptions will be omitted. In the second embodiment, the configuration of the pressing unit 40 is different. The pressing unit 40 has a sheet member 47 instead of the roller 41.
[0040] 8, the sheet member 47 is an elastically deformable member and extends in a strip shape along the cutting direction B. The sheet member 47 has an upstream end and a downstream end in the cutting direction B fixed to the carriage 31, and is curved so as to be convex in the -Z direction. The lower end of the sheet member 47 comes into contact with the surface of the medium P and presses the medium P.
[0041] The sheet member 47 is provided so as to press a position where at least a portion of it overlaps with the contact portion S when viewed from the conveying direction A. Note that the sheet member 47 may be provided so as to press a position downstream of the movable blade 38 in the cutting direction B. The pressing portion 40 may be configured to include the roller 41 of the first embodiment together with the sheet member 47.
[0042] As described above, the recording device 100 according to the second embodiment can provide the following advantages.
[0043] The pressing unit 40 has a sheet member 47. This makes it possible to press the medium P with a simple configuration. In addition, the risk of the pressing unit 40 damaging the medium P can be reduced.
[0044] The sheet member 47 is provided so as to press a position overlapping the contact portion S when viewed from the transport direction A. In other words, the pressing portion 40 is capable of pressing a position overlapping the contact portion S when viewed from the transport direction A. This makes it possible to effectively suppress floating of the medium P in the vicinity of the contact portion S where the movable blade 38 cuts the medium P. Therefore, poor cutting of the medium P can be prevented.
[0045] 3. Embodiment 3 Next, a schematic configuration of a recording device 100 according to a third embodiment will be described. The same components as those in the first embodiment will be given the same reference numerals, and duplicated descriptions will be omitted. In the third embodiment, the recording device 100 includes a tension applying unit 50. When the cutting unit 30 cuts the medium P, the tension applying unit 50 applies tension to the medium P in a direction intersecting the cutting direction B.
[0046] 9, the tension applying unit 50 is provided on the carriage 31. Therefore, as the movable blade 38 moves in the cutting direction B, the tension applying unit 50 also moves in the cutting direction B.
[0047] The tension applying unit 50 has a first tension applying roller 51 as a roller, a rotating shaft 52, a roller support unit 53, and an urging member (not shown). The first tension applying roller 51 is capable of contacting the surface of the medium P and is rotatable around the rotating shaft 52 along a direction intersecting the cutting direction B. Therefore, when the movable blade 38 and the tension applying unit 50 move in the cutting direction B, the first tension applying roller 51 applies tension to the medium P while rotating. The roller support unit 53 and the urging member are similar to those in the first embodiment, and therefore description thereof will be omitted.
[0048] The first tensioning roller 51 is provided upstream of the movable blade 38 in the conveying direction A, and is also provided upstream of the movable blade 38 in the cutting direction B. The first tensioning roller 51 is angled with respect to the cutting direction B so that its downstream end in the cutting direction B is closer to the movement path M of the movable blade 38 than its upstream end in the cutting direction B. Therefore, tension is imparted to the medium P cut by the movable blade 38 in a direction intersecting the cutting direction B by the rotation of the first tensioning roller 51. More specifically, the medium P cut by the movable blade 38 opens so as to move away from the movement path M of the movable blade 38.
[0049] The tensioning unit 50 has a second tensioning roller 54 as a roller. The second tensioning roller 54 is provided downstream of the movable blade 38 in the conveying direction A and upstream of the movable blade 38 in the cutting direction B. The peripheral configuration of the second tensioning roller 54 is similar to that of the first tensioning roller 51, so a description thereof will be omitted. As with the first tensioning roller 51, the second tensioning roller 54 has an angle with respect to the cutting direction B so that the downstream end in the cutting direction B is closer to the moving path M of the movable blade 38 than the upstream end in the cutting direction B. The tensioning unit 50 may have only the first tensioning roller 51 or only the second tensioning roller 54. In other words, the tensioning unit 50 may have a roller at least on either the upstream or downstream side of the movable blade 38 in the conveying direction A.
[0050] Further, in addition to the first tension roller 51 and the second tension roller 54, a pressing unit 40 may be provided. In the configuration shown in FIG. 9, the pressing unit 40 similar to that of the first embodiment, that is, the pressing unit 40 having the roller 41, is disposed upstream of the movable blade 38 in the conveying direction A and downstream of the movable blade 38 in the cutting direction B. However, the configuration of the pressing unit 40 is not limited thereto, and may be, for example, the pressing unit 40 having a sheet member 47 similar to that of the second embodiment. Note that in this embodiment, the pressing unit 40 is not an essential component.
[0051] As described above, the recording device 100 according to the third embodiment can provide the following advantages.
[0052] The recording device 100 includes a recording unit 10 that records on the medium P, a transport unit 20 that transports the medium P in a transport direction A, a cutting unit 30 that cuts the medium P, and a tension applying unit 50 that applies tension to the medium P in a direction intersecting the cutting direction B when the cutting unit 30 cuts the medium P. In this way, the cutting unit 30 can cut the medium P in a state in which tension has been applied by the tension applying unit 50, and therefore can cut the medium P while suppressing floating of the medium P. Therefore, poor cutting of the medium P can be prevented.
[0053] The tension applying unit 50 has a first tension applying roller 51 provided on the carriage 31. The first tension applying roller 51 is provided upstream of the movable blade 38 in the cutting direction B, and has an angle with respect to the cutting direction B such that the downstream end in the cutting direction B is closer to the movement path M than the upstream end in the cutting direction B. In this way, the tension applying unit 50 moves together with the movement of the carriage 31, so that floating of the medium P can be suppressed while the cutting unit 30 cuts the medium P. In addition, since the medium P after cutting is opened by the first tension applying roller 51, it is possible to make it easier to cut the medium P.
[0054] 4. Embodiment 4 Next, a schematic configuration of a recording device 100 according to a fourth embodiment will be described. The same components as those in the third embodiment will be denoted by the same reference numerals, and duplicated descriptions will be omitted. In the fourth embodiment, the configuration of the tension applying unit 50 is different from that in the third embodiment. The tension applying unit 50 in this embodiment has an angle changing unit 60 that changes the angle of the first tension applying roller 51 with respect to the cutting direction B as the carriage 31 moves in the cutting direction B.
[0055] As shown in Figs. 10, 11A and 11B, the angle changing unit 60 has a first gear 61, a second gear 62, a first angle changing blade 63 and a second angle changing blade 64. The first gear 61 is provided on the carriage 31 and is rotatable around a rotation axis along the vertical direction. The roller support unit 53 that supports the first tensioning roller 51 is fixed to the first gear 61. The second gear 62 is provided on the carriage 31 and is rotatable around a rotation axis along the vertical direction. The first gear 61 and the second gear 62 mesh with each other.
[0056] The first angle changing blade 63 and the second angle changing blade 64 are provided at the upstream end of the guide rail 36 in the conveying direction A, and are arranged at a predetermined distance apart along the cutting direction B. The first angle changing blade 63 and the second angle changing blade 64 are protrusions that protrude in the -Y direction, and are capable of meshing with the second gear 62.
[0057] FIG. 11A shows a case where the carriage 31 is located upstream of the first angle changing blade 63 in the cutting direction B. The angle of the first tension roller 51 with respect to the cutting direction B at this time is θ1. When the carriage 31 moves further in the cutting direction B from the state of FIG. 11A, the second gear 62 and the first angle changing blade 63 mesh. When the carriage 31 moves further in the cutting direction B from that state, the first angle changing blade 63 rotates the second gear 62 counterclockwise by a predetermined angle. Since the second gear 62 meshes with the first gear 61, the first gear 61 rotates clockwise with the rotation of the second gear 62. Then, the angle of the first tension roller 51 with respect to the cutting direction B is changed by the rotation of the first gear 61. FIG. 11B shows a state where the second gear 62 passes the first angle changing blade 63 and the angle of the first tension roller 51 with respect to the cutting direction B is changed. If the angle of the first tension roller 51 with respect to the cutting direction B at this time is θ2, then θ2 is smaller than θ1.
[0058] When the carriage 31 further moves in the cutting direction B from the state of FIG. 11B, the angle of the first tension roller 51 with respect to the cutting direction B is further changed from θ2 by the second angle changing blade 64, as in the case of the first angle changing blade 63. Although not shown, if the angle of the first tension roller 51 with respect to the cutting direction B at this time is θ3, θ3 is smaller than θ2. That is, the angle changing unit 60 reduces the angle of the first tension roller 51 with respect to the cutting direction B as the carriage 31 moves in the cutting direction B. After the carriage 31 moves in the cutting direction B to cut the medium P, the angle of the first tension roller 51 with respect to the cutting direction B also returns to its original angle as the carriage 31 returns to the -X direction. Note that the number of angle changing blades may be one, or three or more may be provided.
[0059] As in the third embodiment, a pressing unit 40 may be provided in addition to the tension applying unit 50. In the configuration shown in Fig. 10, the pressing unit 40 similar to that in the first embodiment is disposed upstream of the movable blade 38 in the conveying direction A and downstream of the movable blade 38 in the cutting direction B. However, the configuration of the pressing unit 40 is not limited thereto, and may be, for example, the pressing unit 40 similar to that in the second embodiment. Note that the pressing unit 40 is not an essential component in this embodiment either.
[0060] As described above, the recording device 100 according to the fourth embodiment can provide the following advantages.
[0061] The tension applying unit 50 has an angle changing unit 60 that changes the angle of the first tension applying roller 51 with respect to the cutting direction B as the carriage 31 moves in the cutting direction B. With this, the angle of the first tension applying roller 51 with respect to the cutting direction B is changed as the medium P is cut, thereby reducing the risk of the medium P being damaged due to excessive force being applied to the medium P.
[0062] 5. Embodiment 5 Next, a schematic configuration of the recording device 100 according to the fifth embodiment will be described. The same components as those in the third embodiment will be denoted by the same reference numerals, and duplicated descriptions will be omitted. In the fifth embodiment, the configuration of the tension applying unit 50 is different from that in the third embodiment. The tension applying unit 50 in this embodiment has a tension applying roller pair 57 as a third roller pair. Note that the configuration may further include a tension applying unit 50 similar to that in the third or fourth embodiment.
[0063] 12, the tensioning roller pair 57 is provided downstream of the first discharge roller pair 23 and upstream of the cutting section 30 in the conveying direction A. The tensioning roller pair 57 is also provided upstream of the center of the movement range of the carriage 31 in the cutting direction B. The tensioning roller pair 57 is capable of nipping the medium P with two rollers. Each roller is capable of rotatably moving around an axis of rotation along the cutting direction B.
[0064] When the carriage 31 is located upstream of the tension roller pair 57 in the cutting direction B, the control unit 104 does not rotate the tension roller pair 57. After the carriage 31 moving in the cutting direction B passes the position of the tension roller pair 57, the control unit 104 drives a drive unit (not shown) to rotate the tension roller pair 57. Specifically, the control unit 104 rotates the tension roller pair 57 counterclockwise when viewed along the cutting direction B, that is, in the opposite direction to when the medium P is discharged. In other words, the tension roller pair 57 rotates to apply tension to the medium P cut by the movable blade 38 in a direction intersecting the cutting direction B. In more detail, the medium P cut by the movable blade 38 opens so as to move away from the movement path of the movable blade 38.
[0065] The tension-applying roller pair 57 may be provided downstream of the cutting unit 30 and upstream of the second discharge roller pair 24 in the transport direction A. In this case, the tension-applying roller pair 57 applies tension to the medium P by rotating clockwise when viewed along the cutting direction B. The tension-applying roller pair 57 may be provided both upstream and downstream of the cutting unit 30 in the transport direction A.
[0066] As described above, the recording device 100 according to the fifth embodiment can provide the following advantages.
[0067] The tension applying unit 50 has a pair of tension applying rollers 57 that is rotatable about a rotation axis along the cutting direction B and can nip the medium P. The pair of tension applying rollers 57 is provided upstream of the center of the movement range of the carriage 31 in the cutting direction B, and when the carriage 31 moving in the cutting direction B passes the position of the pair of tension applying rollers 57, it rotates so as to apply tension to the medium P. As a result, the medium P cut by the movable blade 38 opens, making it easier to cut the medium P.
[0068] 6. Embodiment 6 Next, a schematic configuration of a recording device 100 according to a sixth embodiment will be described. In this embodiment, when cutting the medium P by the cutting unit 30, the control unit 104 first cuts the medium P by moving the carriage 31 in the cutting direction B. Thereafter, without transporting the medium P, the control unit 104 moves the carriage 31 in the opposite direction to the cutting direction B to further cut the medium P. The cutting unit 30 passes through the same position on the medium P both when moving in the cutting direction B and when moving in the opposite direction to the cutting direction B.
[0069] The control unit 104 may select whether to cut only in the cutting direction B or to cut in both directions depending on the type of medium P. In particular, when cutting medium P that is difficult to cut in one cutting operation, cutting in both directions may be performed.
[0070] As described above, according to the recording device 100 of the sixth embodiment, the cutting unit 30 cuts the medium P when the carriage 31 moves in the cutting direction B, and then cuts the medium P also when the carriage 31 moves in the direction opposite to the cutting direction B. This makes it possible to reliably cut the medium P by suppressing cutting defects.
[0071] 7.Embodiment 7 Next, a schematic configuration of the recording device 100 according to the seventh embodiment will be described. In this embodiment, when the medium P is cut by the cutting unit 30, the control unit 104 first executes a first operation of moving the carriage 31 to a predetermined position in the cutting direction B at a first speed. Then, after the carriage 31 has moved to the predetermined position, the control unit 104 executes a second operation of moving the carriage 31 in the cutting direction B at a second speed that is faster than the first speed. Here, the predetermined position and the speed difference between the second speed and the first speed may be set in advance in accordance with the type of medium P, or may be configured so that the user can change and adjust them as appropriate.
[0072] As described above, according to the recording device 100 of the seventh embodiment, the control unit 104 executes a first operation of moving the carriage 31 in the cutting direction B at a first speed to a predetermined position, and a second operation of moving the carriage 31 in the cutting direction B at a second speed faster than the first speed after the carriage 31 has moved to the predetermined position. According to this, by slowing down the speed immediately after the start of the cutting operation, cutting defects can be suppressed and the medium P can be cut reliably.
[0073] 8.Embodiment 8 Next, a description will be given of a schematic configuration of a recording device 100 according to embodiment 8. In this embodiment, before the cutting unit 30 cuts the medium P, the control unit 104 executes a drying operation to dry the medium P for a predetermined drying time.
[0074] The control unit 104 changes the drying time according to the type of the medium P. For example, plain paper is more difficult to cut when liquid is absorbed than other types of media P. For this reason, before cutting the recorded plain paper, it is dried for a longer drying time than other types of media P. Also, the larger the amount of liquid discharged from the recording unit 10, the more difficult it is to cut. Therefore, the control unit 104 changes the drying time according to the amount of liquid discharged from the recording unit 10. Specifically, when the amount of liquid discharged is greater than a threshold, the control unit 104 lengthens the drying time compared to when the amount of liquid discharged is equal to or less than the threshold. The drying time may be determined according to both the type of the medium P and the amount of liquid discharged, or may be determined according to either one of them. In other words, the control unit 104 may change the drying time according to at least one of the type of the medium P and the amount of liquid discharged. Also, instead of determining the drying time according to the type of the medium P and the amount of liquid discharged, the user may be able to change and adjust them as appropriate.
[0075] As described above, the recording device 100 according to the eighth embodiment can provide the following advantages.
[0076] The control unit 104 can execute a drying operation to dry the medium P for a predetermined drying time before cutting the medium P by the cutting unit 30. With this, even if the medium P absorbs liquid and is difficult to cut, cutting defects can be suppressed by cutting the medium P after drying it.
[0077] The control unit 104 changes the drying time depending on at least one of the type of medium P and the amount of liquid discharged from the recording unit 10. With this, even if the medium P absorbs the liquid and is difficult to cut, cutting defects can be efficiently suppressed by drying the medium P for a time according to the type of medium P and the amount of liquid discharged.
[0078] The recording device 100 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.
[0079] The pressing unit 40 in the first and second embodiments is not limited to a configuration including the roller 41 and the sheet member 47. Moreover, the pressing unit 40 does not have to be provided on the carriage 31. For example, the pressing unit 40 may be displaceable so as to be in a retracted position where it does not come into contact with the medium P when the medium P is being transported, and to be in an advanced position where it comes into contact with the medium P when the medium P is being cut.
[0080] The pressing portion 40 in the first and second embodiments may be provided so as to be capable of pressing the upstream of the movable blade 38 in the cutting direction B. Furthermore, at least a portion of the pressing portion 40 may be provided so as to overlap the movable blade 38 when viewed along the conveying direction A.
[0081] In the first to eighth embodiments, the rotation speed of the second discharge roller pair 24 may be faster than the rotation speed of the first discharge roller pair 23. This allows the cutting unit 30 to cut the medium P while suppressing floating of the medium P, thereby preventing poor cutting of the medium P.
[0082] In the first to eighth embodiments, the rotation speed of the first discharge roller pair 23 and the rotation speed of the second discharge roller pair 24 may be the same, and the diameter of the second discharge roller pair 24 may be larger than the diameter of the first discharge roller pair 23. In this way, the cutting unit 30 can cut the medium P in a state in which tension is applied, and therefore can cut the medium P while suppressing floating of the medium P. Therefore, poor cutting of the medium P can be prevented. [Explanation of symbols]
