[0008] <Configuration of Recording Device 10> As shown in FIG. 1, the recording device 10 is a device that records an image on a medium 90 shown in FIG. 4. The recording device 10 may be a device that records an image on the medium 90 by ejecting a liquid. The liquid may be, for example, ink. The liquid may be, for example, a plurality of colors or a single color. The medium 90 may be, for example, roll paper 91 and paper 92 shown in FIG. 4. The roll paper 91 is a roll-shaped medium 90. The paper 92 is a sheet-shaped medium 90. The paper 92 is plain paper. The recording device 10 may be a device that can record on a plurality of types of medium 90.

[0009] The recording device 10 includes a housing 11. The housing 11 is the exterior of the recording device 10. The housing 11 constitutes, but is not limited to, the front surface 12, rear surface 13, left side surface 14, right side surface 15, bottom surface 16, and top surface 17 of the recording device 10. The housing 11 may constitute at least a portion of the front surface 12, a portion of the rear surface 13, a portion of the left side surface 14, a portion of the right side surface 15, a portion of the bottom surface 16, and a portion of the top surface 17 of the recording device 10. The housing 11 houses various components that constitute the recording device 10.

[0010] The recording device 10 includes an operation panel 18. The operation panel 18 may be provided on the front face 12. The operation panel 18 may be a touch panel. The operation panel 18 may include an operation unit 18A and a display unit 18B. The operation unit 18A can be operated by a user. The operation unit 18A may be composed of multiple operation areas. The display unit 18B displays information related to the recording device 10.

[0011] The recording device 10 includes a paper output tray 19. The paper output tray 19 is a tray on which the ejected medium 90 after recording is placed. The paper output tray 19 is accessible from the front Y1. The paper output tray 19 may be configured to be extendable and scalable in the front-to-rear direction Y.

[0012] The recording device 10 includes a storage cassette 20. The storage cassette 20 forms part of the front surface 12. The storage cassette 20 is housed in a housing 11. The storage cassette 20 is displaceable in the front-to-rear direction Y. The storage cassette 20 can feed paper by moving it forward Y1 from the housing 11. The storage cassette 20 stores media 90.

[0013] As shown in FIG. 2, the storage cassette 20 includes a front surface 21, a cassette gripping portion 22, a first storage portion 23A, and a second storage portion 23B. The front surface 21 is a wall portion located on the front side Y1. The front surface 21 constitutes a part of the front surface 12. The cassette gripping portion 22 is provided on the front surface 21. The cassette gripping portion 22 can be gripped by a user.

[0014] First storage section 23A is configured to store roll paper 91 as medium 90. Roll paper 91 corresponds to an example of the first medium. Second storage section 23B is configured to store paper 92 shown in FIG. 4 as medium 90. Paper 92 corresponds to an example of the second medium. Either roll paper 91 placed in first storage section 23A or paper 92 placed in second storage section 23B may be configured to be feedable.

[0015] 3, the housing 11 has an opening 11A and an opening / closing cover 11B. The opening 11A is provided on the rear surface 13. The opening 11A allows access to the cutting unit 30 housed in the housing 11.

[0016] The openable cover 11B is a cover that allows the opening 11A to be opened and closed. The openable cover 11B is pivotally attached to the lower portion Z2 of the opening 11A, but is not limited to this and may be pivotally attached to the upper portion Z1 of the opening 11A, for example. In this way, when the openable cover 11B is opened, the housing 11 allows access to the housed cutting unit 30 through the opening 11A.

[0017] Specifically, for example, it becomes possible to clear clogging of the medium 90 and perform maintenance on the cutting section 30. Maintenance on the cutting section 30 includes replacement of the cutter unit 40, which will be described later.

[0018] <Configuration of cover locking portion 70> The recording device 10 includes a cover lock unit 70. The cover lock unit 70 is provided on the housing 11. The cover lock unit 70 is located in an area where the opening 11A is provided. The cover lock unit 70 locks the opening cover 11B when the opening 11A is closed, thereby keeping the opening cover 11B closed. The cover lock unit 70 may be an electromagnetic solenoid.

[0019] More specifically, cover locking unit 70 has a displaceable locking shaft. Cover locking unit 70 locks opening / closing cover 11B with opening 11A closed by inserting the locking shaft into a recess (not shown) provided in opening / closing cover 11B. Cover locking unit 70 unlocks opening / closing cover 11B by retracting the locking shaft from the recess (not shown) provided in opening / closing cover 11B.

[0020] Cover lock unit 70 is configured to lock opening / closing cover 11B when recording device 10 is powered off. Cover lock unit 70 locks opening / closing cover 11B when recording device 10 is powered on, and unlocks opening / closing cover 11B in response to a user instruction. When recording device 10 is powered on, cover lock unit 70 locks opening / closing cover 11B in response to a user instruction while opening / closing cover 11B is unlocked.

[0021] In this way, the cover locking unit 70 locks the opening / closing cover 11B while the opening 11A is closed, thereby restricting the opening of the opening / closing cover 11B. When the opening / closing cover 11B is closed, access to the cutting unit 30 via the opening 11A is restricted. In other words, the cover locking unit 70 restricts access to the cutting unit 30. The cover locking unit 70 corresponds to an example of a restricting unit.

[0022] <Configuration of feeding section 31> 4, the recording device 10 includes a cutting unit 30, a feeding unit 31, a transport unit 32, a recording unit 33, a medium support unit 34, and a control unit 35. The feeding unit 31 is located above the storage cassette 20 in a position Z1 when the storage cassette 20 is attached to the housing 11. The feeding unit 31 is configured to feed the medium 90 placed in the storage cassette 20.

[0023] The feeding unit 31 includes a feeding roller 31A and a roller support unit 31B. The feeding roller 31A is a roller for feeding the medium 90. The roller support unit 31B is rotatably attached at its base end around a rotation shaft 31C. The rotation shaft 31C is an axis extending in the width direction X. The roller support unit 31B is configured to rotatably support the feeding roller 31A at its tip end. The roller support unit 31B is inclined so that the feeding roller 31A comes into contact with the medium 90.

[0024] The storage cassette 20 has a feeding path 20A for the roll paper 91. The feeding path 20A is located below the first storage section 23A and the second storage section 23B in a position Z2. The feeding path 20A connects the first storage section 23A with a transport path 24, which will be described later.

[0025] The storage cassette 20 has a feed flap 20B. The feed flap 20B is attached to a support plate of the second storage section 23B. The feed flap 20B is displaceable between a paper position and a roll paper position. The feed flap 20B may be displaced by rotating or sliding.

[0026] The paper position is a position when recording is performed on paper 92 stored in second storage section 23B. The paper position is a position where paper 92 stored in second storage section 23B is supported by closing an opening or a notch provided in the bottom plate of second storage section 23B.

[0027] The roll paper position is the position when recording on the roll paper 91 stored in the first storage section 23A. The roll paper position is the position where the feed roller 31A comes into contact with the roll paper 91 in the feed path 20A by opening an opening or notch provided in the bottom plate of the second storage section 23B.

[0028] When paper sheets 92 are stored in the second storage section 23B, the tilt of the roller support section 31B causes the feed roller 31A to come into contact with the paper sheets 92. Specifically, the feed roller 31A comes into contact with the paper sheets 92 that are placed at the top Z1 of the paper sheets 92 stored in the second storage section 23B. The feed roller 31A rotates in the feed direction while in contact with the paper sheets 92, thereby feeding the paper sheets 92 that it is in contact with one by one. In this case, the feed flap 20B is positioned at the paper position. This allows the second storage section 23B to stably store the paper sheets 92.

[0029] When the feed flap 20B is positioned at the roll paper position and no paper 92 is stored in the second storage section 23B, the tilt of the roller support section 31B causes the feed roller 31A to come into contact with the roll paper 91 placed in the feed path 20A. The feed roller 31A feeds the roll paper 91 it is in contact with by rotating in the feed direction while in contact with the roll paper 91 in the feed path 20A.

[0030] <Configuration of the conveying unit 32> The transport unit 32 is configured to transport the medium 90. The transport unit 32 transports the medium 90 fed by the feeding unit 31 along the transport path 24 in the transport direction D. The transport path 24 is a path along which the medium 90 is transported.

[0031] The transport path 24 may include a path for transporting the roll paper 91 and a path for transporting the paper 92. The transport path 24 may include a reversing path 24A for reversing the medium 90. The reversing path 24A is a path for transporting the medium 90 that has been reversed by the reversing unit 28, which will be described later.

[0032] The transport unit 32 includes multiple rollers and multiple motors that serve as drive sources. In particular, the transport unit 32 includes a transport roller pair 25. The transport roller pair 25 is located upstream of the medium support unit 34 on the transport path 24. The transport roller pair 25 transports the medium 90 along the transport path 24 to the medium support unit 34.

[0033] The transport unit 32 includes a first discharge roller pair 26 and a second discharge roller pair 27. The first discharge roller pair 26 and the second discharge roller pair 27 are located downstream of the medium support unit 34 on the transport path 24. The second discharge roller pair 27 is located downstream of the first discharge roller pair 26 on the transport path 24. The first discharge roller pair 26 and the second discharge roller pair 27 discharge the recorded medium 90 along the transport path 24.

[0034] The transport unit 32 may include an inverting unit 28. That is, the recording device 10 includes the inverting unit 28. The inverting unit 28 is configured to invert the recorded medium 90. The second discharge roller pair 27 rotates in a direction opposite to the rotation direction for discharging the recorded medium 90, thereby transporting the recorded medium 90 to the inverting unit 28 along the inverting path 24A. The inverting unit 28 is configured to invert the recorded medium 90 that has been transported to the second discharge roller pair 27.

[0035] The inversion unit 28 includes an inversion flap 29. The inversion flap 29 is provided at a position along the inversion path 24A. The inversion flap 29 switches the direction in which the medium 90 is transported. In particular, the inversion flap 29 switches whether or not the medium 90 is transported along the inversion path 24A. In this way, the inversion unit 28 causes the inverted, recorded medium 90 to merge upstream of the medium support unit 34 on the transport path 24.

[0036] As a result, the medium 90, on which an image has been recorded on the front side, is conveyed to the medium support unit 34 in an inverted state by the inverting unit 28. This allows the recording unit 33 to record an image on the back side of the medium 90 as well. In this way, the recording unit 33 can record on both sides of the medium 90. In other words, the recording unit 33 is capable of double-sided printing.

[0037] <Configuration of recording unit 33> The recording unit 33 is configured to record an image on the medium 90. The recording unit 33 may be configured to record an image on the medium 90 by ejecting a liquid onto the medium 90. The recording unit 33 is located above the medium support unit 34 in the direction Z1.

[0038] The recording unit 33 includes a recording carriage 36 and a liquid ejection head 37. The recording carriage 36 supports the liquid ejection head 37 from above Z1. The liquid ejection head 37 is provided below the recording carriage 36 in Z2.

[0039] The liquid ejection head 37 has a nozzle surface 38. The nozzle surface 38 is a surface facing downward Z2. The nozzle surface 38 is a surface facing the medium support unit 34. The nozzle surface 38 is a surface on which a plurality of nozzles (not shown) open. Each of the plurality of nozzles opens toward the medium 90 supported by the medium support unit 34. Each of the plurality of nozzles ejects liquid.

[0040] The liquid ejection head 37 ejects liquid from a plurality of nozzles toward the medium 90 supported by the medium support unit 34. In this way, the recording unit 33 is configured to perform recording on the medium 90 by ejecting liquid onto the medium 90. The liquid ejection head 37 is a serial head type that ejects liquid as the recording carriage 36 moves in the width direction X, but may also be a line head type.

[0041] The medium support unit 34 is configured to support the medium 90. In particular, the medium support unit 34 supports the medium 90 in a recording area where recording is performed on the medium 90 by the recording unit 33. In other words, the medium support unit 34 supports the medium 90 on which recording is performed by the recording unit 33.

[0042] <Configuration of control unit 35> The control unit 35 controls the recording device 10. The control unit 35 controls each unit in the recording device 10. The control unit 35 controls various operations executed in the recording device 10. The control unit 35 may be connected to a terminal device (not shown) so as to be able to communicate with the terminal device.

[0074] The main body 61A has a positioning opening 61D. The positioning opening 61D extends along the front-rear direction Y. When the cutter unit 40 is held by the unit holding part 60 and the unit fixing part 61 moves between the fixing position P21 and the releasing position P22, the positioning part 52 is inserted into and removed from the positioning opening 61D.

[0075] When the unit fixing part 61 is placed at the fixing position P21 while the cutter unit 40 is held by the unit holding part 60, the positioning part 52 is inserted into the positioning opening 61D. As a result, the cutter unit 40 is positioned on the cutter carriage 41 when it is attached to the cutter carriage 41.

[0076] The unit fixing portion 61 includes a locked portion 66. The locked portion 66 may be provided on the main body portion 61A. The locked portion 66 may be provided on the main body portion 61A in the second width direction X2. The locked portion 66 may extend downward Z2 from the main body portion 61A.

[0077] The locked portion 66 has a locking hole 67. The locking hole 67 is provided so as to penetrate the locked portion 66 in the width direction X. The locking hole 67 can hold the unit locking portion 64 by inserting the unit locking portion 64 into it.

[0078] In this way, the unit locking portion 64 can lock the unit fixing portion 61 at the fixing position P21 by being inserted into the locking hole 67 when the unit fixing portion 61 is positioned at the fixing position P21. In other words, the unit locking portion 64 can lock the unit fixing portion 61 to the unit holding portion 60 when the unit fixing portion 61 is positioned at the fixing position P21. This makes it impossible to remove the cutter unit 40 from the cutter carriage 41 when the cutter unit 40 is attached to the cutter carriage 41. The unit locking portion 64 corresponds to an example of a restricting portion.

[0079] <Configuration of first contact portion 71> 8 and 9, the cutting unit 30 has a first abutment portion 71. That is, the recording device 10 has the first abutment portion 71. The first abutment portion 71 is provided on the carriage support portion 42. The first abutment portion 71 is provided on the first width direction X1 side within the movement range of the cutter carriage 41. The first abutment portion 71 is provided at a position where it abuts against the unit locking portion 64 in the first width direction X1 when the cutter carriage 41 is disposed at the standby position P11.

[0080] The first contact portion 71 may include a first protrusion 71A. The first protrusion 71A protrudes in the second width direction X2. The first protrusion 71A can come into contact with the unit locking portion 64 from the first width direction X1 side. In this way, the first contact portion 71 can come into contact with the unit locking portion 64 from the first width direction X1 side.

[0081] When the cutter carriage 41 moves from the attachment / detachment position P12 to the standby position P11, the first abutment portion 71 abuts against the unit locking portion 64 from the side in the first width direction X1, thereby moving the unit locking portion 64 in the second width direction X2. As a result, the unit locking portion 64 is inserted into the locking hole 67.

[0082] In this way, when the cutter carriage 41 moves from the attachment / detachment position P12 to the standby position P11, the first abutment portion 71 abuts against the unit lock portion 64, thereby locking the unit fixing portion 61 to the unit lock portion 64.

[0083] <Configuration of second contact portion 72> 10, the cutting unit 30 has a second abutment portion 72. In other words, the recording device 10 has the second abutment portion 72. The second abutment portion 72 is provided on the carriage support portion 42. The second abutment portion 72 is provided on the second width direction X2 side within the movement range of the cutter carriage 41. The second abutment portion 72 is provided at a position where it abuts against the unit locking portion 64 in the second width direction X2 when the cutter carriage 41 is disposed at the attachment / detachment position P12.

[0084] The second contact portion 72 may include a second protrusion 72A. The second protrusion 72A protrudes in the first width direction X1. The second protrusion 72A can come into contact with the unit locking portion 64 from the second width direction X2 side. In this way, the second contact portion 72 can come into contact with the unit locking portion 64 from the second width direction X2 side.

[0085] When the cutter carriage 41 moves from the standby position P11 to the attachment / detachment position P12, the second abutment portion 72 abuts against the unit locking portion 64 from the second width direction X2 side, thereby moving the unit locking portion 64 in the first width direction X1. As a result, the unit locking portion 64 retreats from the locking hole 67.

[0086] In this way, when the cutter carriage 41 moves from the standby position P11 to the attachment / detachment position P12, the second abutment portion 72 abuts against the unit locking portion 64, causing the unit locking portion 64 to unlock the unit fixing portion 61.

[0087] <Configuration of Restriction Wall 11C> 8, the housing 11 includes a restriction wall 11C. The restriction wall 11C is located behind Y2 the standby position P11 where the cutter unit 40 is disposed. In other words, the restriction wall 11C is provided between the cutter unit 40 disposed at the standby position P11 and the opening 11A.

[0088] A gap is provided in front Y1 of the restricting wall 11C. The gap is a space that allows the cutter unit 40 to move along the width direction X but prevents a user from removing the cutter unit 40. The restricting wall 11C does not restrict movement of the cutter unit 40 along the width direction X.

[0089] In this way, when the opening 11A is open and the cutter unit 40 is positioned at the standby position P11, the regulating wall 11C regulates the removal operation of the cutter unit 40 from the cutter carriage 41 through the opening 11A.

[0090] When the unit fixing portion 61 is positioned at the release position P22 and the cutter unit 40 moves from the attachment / detachment position P12 toward the standby position P11, the unit fixing portion 61 abuts against the side portion 11D of the restriction wall 11C. This prevents the cutter unit 40 from being positioned at the standby position P11. In this way, the restriction wall 11C abuts against the unit fixing portion 61, thereby restricting the movement of the cutter unit 40 toward the standby position P11. The restriction wall 11C corresponds to an example of a restriction portion.

[0091] <Exchange control process> Next, the exchange control process will be described with reference to Fig. 11. The exchange control process is a process executed by the control unit 35 at predetermined intervals.

[0092] 11, in step S10, the control unit 35 determines whether or not a replacement instruction has been input. The replacement instruction is an instruction from the user. The instruction from the user is an instruction from the operation unit 18A, but may also be an instruction from a terminal device (not shown).

[0093] If the control unit 35 determines that a replacement instruction has not been input, the control unit 35 proceeds to step S13. If the control unit 35 determines that a replacement instruction has been input, the control unit 35 proceeds to step S11.

[0094] In step S11, the control unit 35 executes a mounting / detaching position movement process. In this process, the control unit 35 controls the carriage movement unit 44 to move the cutter carriage 41 from the standby position P11 to the mounting / detaching position P12. As a result, the cutter carriage 41 moves from the standby position P11 to the mounting / detaching position P12 in response to an instruction from the user.

[0095] When the cutter carriage 41 moves to the attachment / detachment position P12, the second abutment portion 72 abuts against the unit locking portion 64. This causes the unit locking portion 64 to retreat from the locking hole 67. In this way, the unit locking portion 64 releases the lock on the unit fixing portion 61. In this way, the unit locking portion 64 releases the lock on the unit fixing portion 61.

[0096] In step S12, control unit 35 executes a cover unlocking process. In this process, control unit 35 controls cover lock unit 70 to unlock opening / closing cover 11B. In this manner, cover lock unit 70 unlocks opening / closing cover 11B in response to an instruction from the user.

[0097] In step S13, the control unit 35 determines whether an exchange completion instruction has been input. The exchange completion instruction is an instruction from the user. If the control unit 35 determines that an exchange completion instruction has not been input, it terminates the exchange control process. If the control unit 35 determines that an exchange completion instruction has been input, it proceeds to step S14.

[0098] In step S14, control unit 35 executes a cover lock process. In this process, control unit 35 controls cover lock unit 70 to lock opening / closing cover 11B. In this manner, cover lock unit 70 locks opening / closing cover 11B in response to an instruction from the user.

[0099] In step S15, the control unit 35 executes a standby position movement process. In this process, the control unit 35 controls the carriage movement unit 44 to move the cutter carriage 41 from the attachment / detachment position P12 to the standby position P11. As a result, the cutter carriage 41 moves from the attachment / detachment position P12 to the standby position P11 in response to an instruction from the user.

[0100] When the cutter carriage 41 moves to the standby position P11, the first abutment portion 71 abuts against the unit locking portion 64. This causes the unit locking portion 64 to be inserted into the locking hole 67. In this manner, the unit fixing portion 61 is locked by the unit locking portion 64. In this manner, the unit locking portion 64 locks the unit fixing portion 61.

[0101] In step S16, the control unit 35 determines whether a predetermined error has occurred. The predetermined error is an error related to the movement of the cutter carriage 41. The predetermined error occurs when the cutter carriage 41 does not move to the standby position P11 even after a predetermined time has elapsed since the input of the replacement completion command.

[0102] If the control unit 35 determines that a predetermined error has not occurred, it ends the exchange control process. If the control unit 35 determines that a predetermined error has occurred, it proceeds to step S17.

[0103] In step S17, the control unit 35 executes a predetermined error notification process. In this process, the control unit 35 stops the movement of the cutter carriage 41. The control unit 35 notifies the user of the occurrence of the predetermined error by displaying information about the occurrence of the predetermined error on the display unit 18B.

[0104] The control unit 35 may notify the user of the occurrence of the predetermined error by outputting information about the occurrence of the predetermined error from a speaker (not shown).The control unit 35 may notify the user of the occurrence of the predetermined error by causing an error lamp (not shown) to emit light.The control unit 35 may notify the user of the occurrence of the predetermined error by transmitting information about the occurrence of the predetermined error to the terminal device.

[0105] <Actions and Effects of the First Embodiment> The operation and effects of the first embodiment will be described. (1-1) Removal of the cutter unit 40 from the cutter carriage 41 is restricted. With this configuration, it is possible to restrict removal of the cutter unit 40 having the cutter blade 50 from the cutter carriage 41. This makes it possible to prevent the user from unintentionally removing the cutter unit 40 from the cutter carriage 41. Therefore, safety for the cutter blade 50 can be improved.

[0106] (1-2) The cover locking section 70 locks the openable cover 11B when the opening 11A is closed. With this configuration, the openable cover 11B is locked when the opening 11A is closed, thereby restricting the removal operation of the cutter unit 40 from the cutter carriage 41. This prevents the user from unintentionally removing the cutter unit 40 from the cutter carriage 41. Therefore, the safety of the cutter blade 50 can be improved.

[0107] (1-3) The cover locking unit 70 unlocks the openable cover 11B in response to a user instruction. With this configuration, the user can unlock the openable cover 11B as intended, thereby enabling the cutter unit 40 to be removed from the cutter carriage 41. This prevents the user from unintentionally removing the cutter unit 40 from the cutter carriage 41. This improves the safety of the cutter blade 50.

[0108] (1-4) When the opening 11A is open and the cutter carriage 41 is positioned at the standby position P11, the regulating wall 11C regulates the removal of the cutter unit 40 from the cutter carriage 41 via the opening 11A. With this configuration, the regulating wall 11C can regulate the removal of the cutter unit 40 from the cutter carriage 41. This can prevent the user from unintentionally removing the cutter unit 40 from the cutter carriage 41. Therefore, the safety of the cutter blade 50 can be improved.

[0109] (1-5) The cutter carriage 41 moves from the standby position P11 to the detachment position P12 in response to an instruction from the user. With this configuration, the cutter carriage 41 can be moved from the standby position P11 to the detachment position P12 as intended by the user, thereby enabling the cutter unit 40 to be detached from the cutter carriage 41. This makes it possible to prevent the user from unintentionally detaching the cutter unit 40 from the cutter carriage 41. Therefore, safety for the cutter blade 50 can be improved.

[0110] (1-6) When the cutter carriage 41 moves from the attachment / detachment position P12 to the standby position P11 while the unit fixing portion 61 is positioned at the release position P22, the regulating wall 11C abuts against the unit fixing portion 61. This prevents the cutter carriage 41 from moving to the standby position P11. This configuration prevents the cutter carriage 41 from moving from the attachment / detachment position P12 to the standby position P11 while the unit fixing portion 61 is positioned at the release position P22. This makes it easier for the user to recognize that the unit fixing portion 61 is not positioned at the fixing position P21. This prevents the user from unintentionally removing the cutter unit 40 from the cutter carriage 41. This improves safety for the cutter blade 50.

[0111] (1-7) When the first contact portion 71 comes into contact with the unit lock portion 64, the unit lock portion 64 locks the unit fixing portion 61. According to this configuration, when the first contact portion 71 comes into contact with the unit lock portion 64, the unit fixing portion 61 can be locked at the fixing position P21. This makes it possible to prevent the user from unintentionally removing the cutter unit 40 from the cutter carriage 41. Therefore, safety for the cutter blade 50 can be improved.

[0112] (1-8) When the second contact portion 72 comes into contact with the unit lock portion 64, the unit lock portion 64 unlocks the unit fixing portion 61. With this configuration, the second contact portion 72 comes into contact with the unit lock portion 64, thereby unlocking the unit fixing portion 61. In such a case, the unit fixing portion 61 can be moved to the unlocking position P22, allowing the cutter unit 40 to be removed from the cutter carriage 41. This prevents the user from unintentionally removing the cutter unit 40 from the cutter carriage 41. Therefore, the safety of the cutter blade 50 can be improved.

[0113] (1-9) When the cutter carriage 41 moves from the attachment / detachment position P12 to the standby position P11, the first abutment portion 71 abuts against the unit lock portion 64, thereby locking the unit fixing portion 61 to the unit lock portion 64. According to this configuration, when the cutter carriage 41 moves from the attachment / detachment position P12 to the standby position P11, the first abutment portion 71 abuts against the unit lock portion 64, thereby locking the unit fixing portion 61. This makes it possible to prevent the user from unintentionally removing the cutter unit 40 from the cutter carriage 41, and also makes it possible to switch the lock state of the unit fixing portion 61 as the cutter carriage 41 moves. Therefore, safety for the cutter blade 50 can be improved.

[0114] (1-10) When the cutter carriage 41 moves from the standby position P11 to the attachment / detachment position P12, the second abutment portion 72 comes into contact with the unit lock portion 64, causing the unit lock portion 64 to unlock the unit fixing portion 61. According to this configuration, when the cutter carriage 41 moves from the standby position P11 to the attachment / detachment position P12, the second abutment portion 72 comes into contact with the unit lock portion 64, causing the unit fixing portion 61 to unlock. This makes it possible to prevent the user from unintentionally removing the cutter unit 40 from the cutter carriage 41, and also makes it possible to switch the lock of the unit fixing portion 61 as the cutter carriage 41 moves. Therefore, safety for the cutter blade 50 can be improved.

[0115] [Second embodiment] Next, a second embodiment will be described. In the following description, the same configuration as in the already described embodiment will be omitted or simplified, and only the configuration different from the already described embodiment will be described.

[0116] 12 and 13, in the second embodiment, the cutter carriage 41 includes a unit locking portion 80. The unit locking portion 80 can lock the unit fixing portion 61 when the unit locking portion 80 is disposed at the fixing position P21. The unit locking portion 80 may include a displacement portion 83, which will be described later.

[0117] The unit holding portion 60 has a pair of locked portions 81. The pair of locked portions 81 are arranged side by side in the width direction X. The pair of locked portions 81 are arranged on the outer sides of the unit holding portion 60 in the width direction X. The locked portions 81 are arranged in a position close to the rear Y2 side of the unit holding portion 60. The locked portions 81 have a through hole 82. The through hole 82 is fitted with a protrusion 86, which will be described later. The through hole 82 is arranged to penetrate the unit holding portion 60 in the width direction X.

[0118] The unit fixing portion 61 includes a displacement portion 83. The unit fixing portion 61 may include a pair of displacement portions 83. The pair of displacement portions 83 are arranged side by side in the width direction X. The pair of displacement portions 83 are provided on the outer sides of the main body portion 61A in the width direction X. The displacement portions 83 are provided on the rear Y2 side of the main body portion 61A.

[0119] The displacement portion 83 is displaced by applying a pressing force to the inside of the unit fixing portion 61 in the width direction X. In other words, the displacement portion 83 is displaced in the width direction X that intersects with the release direction R. The width direction X corresponds to an example of a displacement direction.

[0120] The displacement portion 83 includes a flexible portion 84. The flexible portion 84 bends in the width direction X when a pressing force is applied to the inside of the unit fixing portion 61 in the width direction X. The flexible portion 84 has a V-shape when viewed from the rear Y2, but is not limited to this.

[0121] The flexible portion 84 includes a grip portion 85. The grip portion 85 is provided at the upper end of the flexible portion 84. When the unit fixing portion 61 is arranged at the fixing position P21, the grip portion 85 is located at a position Z1 above the main body portion 61A. In other words, even when the unit fixing portion 61 is arranged at the fixing position P21, the grip portion 85 can be held by the user.

[0122] The grip portion 85 can be gripped by the user when displacing the displacement portion 83 inward in the width direction X of the unit fixing portion 61 to unlock the unit fixing portion 61. The grip portion 85 can also be gripped by the user when moving the unit fixing portion 61 between the fixing position P21 and the unlocking position P22.

[0123] The flexible portion 84 includes a protrusion 86. The protrusion 86 is provided so as to protrude outward in the width direction X of the flexible portion 84. The protrusion 86 fits into the through-hole 82 when the unit fixing portion 61 is disposed at the fixing position P21. The protrusion 86 has a shape that includes an inclined surface and an upper surface, but is not limited to this. The inclined surface is provided so as to protrude outward in the width direction X as it extends upward Z1.

[0124] While the unit fixing portion 61 is moving from the release position P22 to the fixing position P21, the inclined surface of the protruding portion 86 comes into contact with the upper surface of the locked portion 81. This causes the flexible portion 84 to bend inward in the width direction X.

[0125] When the unit fixing part 61 moves from the release position P22 to the fixing position P21, the protrusion 86 fits into the through-hole 82. This prevents the flexible part 84 from bending in the width direction X. This causes the displacement part 83 to restrict movement of the unit fixing part 61 from the fixing position P21 in the release direction R.

[0126] When the user presses the displacement portion 83 inward in the width direction X while the unit fixing portion 61 is disposed at the fixing position P21, the flexible portion 84 bends inward in the width direction X. This causes the protrusion 86 to retract from the through-hole 82. In this case, the unit fixing portion 61 becomes movable from the fixing position P21 to the release position P22. In this way, the displacement portion 83 allows the unit fixing portion 61 to move from the fixing position P21 in the release direction R by displacement in the width direction X. The displacement portion 83 corresponds to an example of a restricting portion.

[0127] <Actions and Effects of the Second Embodiment> The operation and effects of the second embodiment will be described. (2-1) According to this configuration, the displacement of the displacement portion 83 in the width direction X allows the unit fixing portion 61 to move from the fixing position P21 in the release direction R. In this way, the displacement of the displacement portion 83 in the width direction X, which intersects with the release direction R, allows the unit fixing portion 61 to move from the fixing position P21 in the release direction R. As a result, because the release direction R intersects with the width direction X, it is possible to prevent the user from unintentionally removing the cutter unit 40 from the cutter carriage 41. Therefore, it is possible to improve the safety of the cutter blade 50.

[0128] [Example of change] This embodiment can be modified as follows: This embodiment and the following modifications can be combined and implemented within the scope of technical compatibility.

[0129] In the first embodiment, the first contact portion 71 may have any shape, such as a flat shape, as long as it can lock the unit fixing portion 61 by contacting the unit locking portion 64. The second contact portion 72 may have any shape, such as a flat shape, as long as it can lock the unit fixing portion 61 by contacting the unit locking portion 64. The recording device 10 does not have to have at least one of the first contact portion 71 and the second contact portion 72.

[0130] In the second embodiment, the locked portion 81 may have a recess provided in the width direction X of the unit holding portion 60, instead of the through hole 82. The recess may be provided on the inside of the unit holding portion 60 in the width direction X, but is not limited to this.

[0131] In the second embodiment, the displacement portion 83 may be another type, such as a push latch, as long as it is displaceable in a displacement direction that intersects with the release direction R. The displacement direction may be the front-to-rear direction Y as long as it intersects with the release direction R.

[0132] Recording device 10 may include an open / close detection unit that detects whether opening / closing cover 11B is closed. Control unit 35 may execute steps S14 to S17 of the replacement control process when opening / closing detection unit detects that opening / closing cover 11B is closed. Control unit 35 may execute steps S14 to S17 of the replacement control process when a replacement completion instruction is input and opening / closing cover 11B is closed.

[0133] The control unit 35 may determine whether a predetermined error has occurred when the position information of the cutter carriage 41 is outside an allowable range when a replacement completion instruction is input. The allowable range is a range of position information that takes into account the standard movement of the cutter carriage 41, and is a range within which it is determined that a predetermined error has not occurred. The control unit 35 may determine whether a predetermined error has occurred not only when a replacement completion instruction is input.

[0134] The unit locking portion 64 may be provided on at least one of the unit holding portion 60 and the unit fixing portion 61. In other words, the unit locking portion 64 may be provided on either the unit holding portion 60 or the unit fixing portion 61, or may be provided so as to straddle both the unit holding portion 60 and the unit fixing portion 61.

[0135] The unit fixing part 61 may be configured to move linearly relative to the unit holding part 60. In other words, the unit fixing part 61 may be configured to move relative to the unit holding part 60.

[0136] The restricting portion may include at least one of the cover locking portion 70, the restricting wall 11C, and the unit locking portion 64. The recording device 10 may include both the first contacting portion 71 and the second contacting portion 72 in the first embodiment and the displacement portion 83 in the second embodiment.

[0137] A lateral printer may be used as the recording device 10. A lateral printer is a printer in which the recording carriage 36 is movable in two directions, the main scanning direction and the sub-scanning direction.

[0138] The cutter unit 40 has a cutter blade 50 that cuts the medium 90, but is not limited to this. For example, the cutter unit 40 may have a cutter blade that processes the medium 90 to crease the medium 90. In this way, the cutter unit 40 may be any unit that has a cutter blade for processing the medium 90 on the transport path 24. In other words, the recording device 10 may be provided with a processing unit.

[0139] The recording device 10 may be configured to record an image on at least one of roll paper 91 and paper 92 as the medium 90. The medium 90 may be of any type as long as it can be processed by the cutter blade 50 in the recording device 10. The medium 90 may be paper, a resin film or sheet, a resin-metal composite film, a laminate film, a woven fabric, a nonwoven fabric, a metal foil, a metal film, a ceramic sheet, clothing, or the like.

[0140] The liquid can be any liquid that can be applied to the medium 90 to record on the medium 90. For example, ink includes particles of functional materials made of solids such as pigments or metal particles dissolved, dispersed, or mixed in a solvent, and includes various compositions such as water-based ink, oil-based ink, gel ink, and hot-melt ink.

[0141] The recording device 10 is not limited to an inkjet printer, but may be a dot impact printer. The recording method of the recording device 10 may be a laser method instead of an inkjet method.

[0142] The phrase "at least any" used herein means one or more of the desired options. As an example, when the number of options is two, the phrase "at least any" used herein means only one option or both options. As another example, when the number of options is three or more, the phrase "at least any" used herein means only one option or any combination of two or more options.

[0143] [Note] The technical concepts and their effects that can be understood from the above-described embodiments and modifications will be described below. The technical concepts and their effects can be combined with each other to the extent that they are not technically inconsistent.

[0144] (A) The recording device includes a transport section that transports a medium in a transport direction along a transport path, a recording section that records an image on the medium transported by the transport section, a cutter unit having a cutter blade for processing the medium on the transport path, a cutter carriage that is detachable from the cutter unit and moves in a width direction that intersects with the transport direction, and a regulating section that regulates the removal of the cutter unit from the cutter carriage.

[0145] This configuration can restrict the removal of the cutter unit having the cutter blade from the cutter carriage, thereby preventing the user from unintentionally removing the cutter unit from the cutter carriage, thereby improving the safety of the cutter blade.

[0146] (B) The recording device includes a housing having an opening and an opening / closing cover that can open and close the opening, the housing houses at least the cutter unit and the cutter carriage and enables the cutter unit to be removed from the cutter carriage via the opening, and the regulating unit may have a cover locking unit that locks the opening / closing cover when the opening is closed.

[0147] With this configuration, the opening and closing cover is locked, restricting the removal of the cutter unit from the cutter carriage. This prevents the user from unintentionally removing the cutter unit from the cutter carriage. This improves the safety of the cutter blade.

[0148] (C) In the above recording device, the cover locking unit may unlock the opening / closing cover in response to an instruction from a user. With this configuration, the user can unlock the open / close cover as intended, allowing the user to remove the cutter unit from the cutter carriage. This prevents the user from unintentionally removing the cutter unit from the cutter carriage, thereby improving the safety of the cutter blade.

[0149] (D) The recording device includes a housing having an opening and an opening / closing cover that can open and close the opening, the housing houses at least the cutter unit and the cutter carriage and allows the cutter unit to be removed from the cutter carriage through the opening, the cutter carriage is movable between a standby position and an attachment / detachment position, and the regulating section may have a regulating wall that regulates the removal of the cutter unit from the cutter carriage through the opening when the opening is open and the cutter carriage is positioned at the standby position.

[0150] With this configuration, the restriction wall can restrict the removal operation of the cutter unit from the cutter carriage, thereby preventing the user from unintentionally removing the cutter unit from the cutter carriage, thereby improving the safety of the cutter blade.

[0151] (E) In the above recording device, the cutter carriage may move from the standby position to the attachment / detachment position in response to an instruction from a user. With this configuration, the user can move the cutter carriage from the standby position to the detachment position as intended, enabling the cutter unit to be detached from the cutter carriage. This prevents the user from unintentionally detaching the cutter unit from the cutter carriage, thereby improving the safety of the cutter blade.

[0152] (F) In the above recording device, the cutter carriage has a unit fixing portion that fixes the cutter unit when the cutter unit is attached, and the unit fixing portion is movable between a fixed position that fixes the cutter unit and a release position that does not fix the cutter unit, and when the unit fixing portion is positioned in the release position and the cutter carriage moves from the attachment / detachment position toward the standby position, the regulating wall may abut against the unit fixing portion to regulate the movement of the cutter carriage to the standby position.

[0153] With this configuration, when the unit fixing portion is in the release position, movement of the cutter carriage from the attachment / detachment position to the standby position can be restricted. This makes it easier for the user to recognize that the unit fixing portion is not in the fixed position. This prevents the user from unintentionally removing the cutter unit from the cutter carriage. Therefore, safety for the cutter blade can be improved.

[0154] (G) The recording device has a first abutment portion, and the cutter carriage has a unit fixing portion that is movable between a fixed position that fixes the cutter unit when the cutter unit is attached and a release position that does not fix the cutter unit, and a unit locking portion that can lock the unit fixing portion when the unit fixing portion is positioned at the fixed position, and the regulating portion has the unit locking portion, and the first abutment portion may lock the unit fixing portion to the unit locking portion by abutting against the unit locking portion.

[0155] According to this configuration, the first abutment portion abuts against the unit locking portion, thereby locking the unit fixing portion in the fixing position. This prevents the user from unintentionally removing the cutter unit from the cutter carriage. Therefore, safety for the cutter blade can be improved.

[0156] (H) The recording device is provided with a second abutment portion, and the cutter carriage has a unit fixing portion that is movable between a fixed position that fixes the cutter unit when the cutter unit is attached and an unlocked position that does not fix the cutter unit, and a unit locking portion that can lock the unit fixing portion when the unit fixing portion is positioned at the fixed position, and the regulating portion has the unit locking portion, and the second abutment portion may cause the unit locking portion to unlock the unit fixing portion by abutting against the unit locking portion.

[0157] According to this configuration, the second abutment portion abuts against the unit lock portion, thereby unlocking the unit fixing portion. In such a case, the unit fixing portion can be moved to the unlocked position, allowing the cutter unit to be removed from the cutter carriage. This prevents the user from unintentionally removing the cutter unit from the cutter carriage. Therefore, the safety of the cutter blade can be improved.

[0158] (I) The above-mentioned recording device comprises a first abutment portion and a second abutment portion, and the cutter carriage has a unit fixing portion that is movable between a fixed position that fixes the cutter unit when the cutter unit is attached and an unlocked position that does not fix the cutter unit, and a unit locking portion that can lock the unit fixing portion when the unit fixing portion is positioned at the fixed position, the cutter carriage is movable between a standby position and an attachment / detachment position, the regulating portion has the unit locking portion, and when the cutter carriage moves from the attachment / detachment position to the standby position, the first abutment portion locks the unit fixing portion to the unit locking portion by abutting against the unit locking portion, and when the cutter carriage moves from the standby position to the attachment / detachment position, the second abutment portion unlocks the unit fixing portion by abutting against the unit locking portion.

[0159] According to this configuration, when the cutter carriage moves from the attachment / detachment position to the standby position, the first abutment portion abuts against the unit lock portion, thereby locking the unit fixing portion. When the cutter carriage moves from the standby position to the attachment / detachment position, the second abutment portion abuts against the unit lock portion, thereby unlocking the unit fixing portion. This prevents the user from unintentionally removing the cutter unit from the cutter carriage, and allows the lock of the unit fixing portion to be switched as the cutter carriage moves. Therefore, safety for the cutter blade can be improved.

[0160] (J) In the above recording device, the cutter carriage has a unit fixing part that is movable between a fixed position in which the cutter unit is fixed when the cutter unit is attached and a release position in which the cutter unit is not fixed, and a unit locking part that can lock the unit fixing part when the unit fixing part is disposed at the fixed position, and the unit fixing part can be moved to the release position by moving from the fixed position in a release direction, and the unit locking part has a displacement part that displaces in a displacement direction that intersects the release direction, and the displacement part may allow the unit fixing part to move from the fixed position to the release direction by displacement in the displacement direction.

[0161] With this configuration, the displacement of the displacement part in the displacement direction intersecting the release direction allows the unit fixing part to move from its fixed position in the release direction. As a result, because the release direction and the displacement direction intersect, it is possible to prevent the user from unintentionally removing the cutter unit from the cutter carriage. Therefore, safety for the cutter blade can be improved. [Explanation of symbols]
