[0014] An embodiment of a recording device and a recording device control method is described below with reference to the drawings. The recording device is an inkjet printer that ejects ink, an example of liquid, onto a medium such as paper, cloth, vinyl, plastic parts, or metal parts to perform recording.

[0015] In the accompanying drawings, the recording device 11 is a device placed on a horizontal plane, and the direction of gravity is indicated by the Z axis, and the direction along the horizontal plane is indicated by the X axis and the Y axis. The X axis, the Y axis, and the Z axis are orthogonal to each other. In the following description, the direction parallel to the X axis is also referred to as the width direction X, the direction parallel to the Y axis is also referred to as the depth direction Y, and the direction parallel to the Z axis is also referred to as the vertical direction Z.

[0016] <Recording Device>

[0017] like Figure 1As shown, the recording device 11 may include a medium storage unit 12 , a stacker 13 , and a touch panel 14 .

[0018] The medium storage unit 12 can store a plurality of media 16. The stacker 13 receives the recorded media 16. The touch panel 14 functions as an operation unit for operating the recording device 11. The touch panel 14 functions as a notification unit for providing notification by displaying a message, for example.

[0019] The recording device 11 includes an opening and closing cover 18. The opening and closing cover 18 may be provided on the front side of the device. The opening and closing cover 18 can be opened and closed. The opening and closing cover 18 may also be moved to the left side by rotating around a hinge (not shown). Figure 1 A closed position is shown and an open position is not shown.

[0020] The opening and closing cover 18 in the closed position covers and hides the maintenance hole 19. The state in which the opening and closing cover 18 is in the closed position is also referred to as a closed state. In the closed state, the inside of the device cannot be accessed from the outside.

[0021] The opening and closing cover 18 in the open position exposes the maintenance hole 19. The state in which the opening and closing cover 18 is in the open position is also referred to as the open state. In the open state, the inside of the device can be accessed from the outside. In the open state, the user can access the inside of the device from the maintenance hole 19.

[0022] The recording device 11 may include a detection unit 21. The detection unit 21 can detect the open state and the closed state of the opening and closing cover 18.

[0023] The recording device 11 includes a control unit 22. The control unit 22 centrally controls the driving of each mechanism in the recording device 11. The control unit 22 controls various operations performed by the recording device 11.

[0024] The control unit 22 can be configured to include the following circuits: α: one or more processors that execute various processes according to a computer program, β: one or more dedicated hardware circuits that execute at least a part of the various processes, or γ: a combination thereof. The hardware circuit is, for example, an integrated circuit for a specific purpose. The processor includes a CPU and a memory such as a RAM and a ROM, and the memory stores a program code or instruction configured to cause the CPU to execute a process. The memory, i.e., a computer-readable medium, includes any readable medium that can be accessed by a general-purpose or dedicated computer.

[0025] The control unit 22 may also function as the counting unit 23 by executing a program stored in the memory. Therefore, it can be said that the recording device 11 includes the counting unit 23. The counting unit 23 counts the number of recorded sheets. The number of recorded sheets is the number of sheets of the medium 16 on which the recording is performed. The counting unit 23 may also count the number of sheets of the medium 16 fed from the medium storage unit 12 as the number of recorded sheets. The counting unit 23 may also count the number of sheets of the medium 16 discharged to the stacker 13 as the number of recorded sheets.

[0026] <Internal Structure>

[0027] like Figure 2 As shown in FIG. 1 , the recording device 11 includes a recording unit 25 and a transport unit 26. The recording device 11 may also include a static elimination unit 27, a transport detection unit 28, a driving unit 29, a displacement mechanism 30, a cleaning unit 31, and a moving body 32. Figure 2 In FIG. 1 , the position of the maintenance hole 19 is shown by a dotted line.

[0028] The recording unit 25 records on the medium 16. The recording unit 25 may also include a liquid ejection head 34. The liquid ejection head 34 can eject liquid from the nozzle 35. The liquid ejection head 34 may also have a nozzle face 36 in which a plurality of nozzles 35 are opened. The liquid ejection head 34 may also be a line type that ejects liquid to the transported medium 16 in a stopped state. The liquid ejection head 34 may also be a serial type that ejects liquid while moving.

[0029] The transport unit 26 transports the medium 16. The transport unit 26 moves along Figure 2 The conveying path 38 indicated by a dashed line in FIG. 2 conveys the medium 16. The conveying unit 26 conveys the medium 16 in a conveying direction Dc. The conveying direction Dc is a direction along the conveying path 38. The conveying unit 26 may include a conveying roller 39, a conveying belt 40, a driving pulley 41, a driven pulley 42, and a frame 43.

[0030] The transport unit 26 may include a plurality of transport rollers 39 . The transport rollers 39 rotate while sandwiching the medium 16 , thereby transporting the medium 16 .

[0031] The conveyor belt 40 is annular. The conveyor belt 40 can be opposite to the recording unit 25. The conveyor belt 40 is mounted on a driving pulley 41 and a driven pulley 42. The frame 43 supports the driving pulley 41 and the driven pulley 42, and the driving pulley 41 and the driven pulley 42 can rotate separately. The driven pulley 42 is rotatably provided. The driven pulley 42 is driven to rotate relative to the circulating conveyor belt 40. The conveyor belt 40 rotates in a state where the medium 16 is electrostatically adsorbed, thereby conveying the medium 16.

[0032] The static eliminator 27 may be formed of a brush. The static eliminator 27 is in contact with the conveyor belt 40. The static eliminator 27 can be in contact with the medium 16 supported by the conveyor belt 40. The static eliminator 27 removes electric charges from the surface of the medium 16 conveyed by the conveyor belt 40.

[0033] The transport detection unit 28 can detect the medium 16 being transported. The transport detection unit 28 may detect the medium 16 supported by the transport belt 40 . The transport detection unit 28 may detect the medium 16 sandwiched between the transport belt 40 and the static elimination unit 27 .

[0034] The driving unit 29 drives the conveying unit 26. The driving unit 29 may rotate the driving pulley 41. The driving unit 29 may rotate the conveying belt 40 by rotating the driving pulley 41. The driving unit 29 may rotate one or more conveying rollers 39.

[0035] The displacement mechanism 30 may include a displacement motor 45 , a rotating shaft 46 , a first link plate 47 , and a second link plate 48 .

[0036] The rotating shaft 46 is rotated by the drive of the displacement motor 45. One end of the first link plate 47 is fixed to the rotating shaft 46. The second link plate 48 is rotatably mounted on the other end of the first link plate 47. One end of the second link plate 48 is mounted on the first link plate 47. The other end of the second link plate 48 is mounted on the frame 43.

[0037] The displacement mechanism 30 can also displace the conveyor belt 40 by rotating the frame 43 around the driving pulley 41. The displacement mechanism 30 displaces the conveyor belt 40 to Figure 2 The conveying position P1 shown, Figure 3 The retreat position P2 shown, and Figure 4 The conveyor belt 40 may be movable to the conveying position P1, the retreating position P2, and the processing position P3.

[0038] like Figure 2 As shown, the conveying position P1 is a position in a recording state in which the recording unit 25 performs recording. In the recording state, the driving pulley 41 and the driven pulley 42 are arranged in the width direction X. The conveying belt 40 located at the conveying position P1 faces the nozzle surface 36 across the conveying path 38. The conveying belt 40 supports a part of the medium 16 in a flat state. The conveying belt 40 located at the conveying position P1 sandwiches the medium 16 between the neutralizing unit 27.

[0039] like Figure 3 As shown, the retreat position P2 is a position when the recording unit 25 is in a standby state without recording. In the standby state, the driving pulley 41 and the driven pulley 42 are aligned in the vertical direction Z. The retreat position P2 is a position where the conveyor belt 40 is away from the recording unit 25 .

[0040] like Figure 4 As shown, the processing position P3 is, for example, a position for processing a clogged medium 16. The processing position P3 is a position between the conveying position P1 and the retreating position P2. The conveying belt 40 at the processing position P3 is away from the static eliminating unit 27.

[0041] like Figure 2 As shown, the cleaning unit 31 cleans the conveying unit 26. The cleaning unit 31 may include a scraper 50 that can contact the conveying belt 40. The scraper 50 can contact the conveying belt 40 in the depth direction Y. The scraper 50 contacts the conveying belt 40 that is circulating, thereby cleaning by scraping foreign matter such as paper dust attached to the conveying belt 40. The cleaning unit 31 separates the foreign matter from the conveying belt 40. The cleaning unit 31 may also be able to move to the conveying position P1, the retreat position P2, and the processing position P3 together with the conveying belt 40.

[0042] The moving body 32 is provided to be movable. The moving body 32 may include a cover 52 and a cover moving mechanism 53. The cover moving mechanism 53 is a mechanism for moving the cover 52. The cover 52 can be moved to Figure 2 The standby position P4 and Figure 3 The entry position P5 is shown. The standby position P4 is the position in the recording state. The entry position P5 is the position in the standby state.

[0043] The cover moving mechanism 53 may include a moving motor 55 , a screw shaft 56 , a slider 57 , a first link member 58 , a second link member 59 , and a wall portion 60 .

[0044] The moving motor 55 can rotate in both forward and reverse directions. The screw shaft 56 can rotate in both forward and reverse directions along with the rotation of the moving motor 55. The screw shaft 56 extends in the width direction X. The slider 57 is screwed with the screw shaft 56. The slider 57 moves in the width direction X or in the direction opposite to the width direction X along with the rotation of the screw shaft 56.

[0045] The first link member 58 connects the slider 57 and the cover 52. The second link member 59 connects the wall portion 60 and the cover 52. The second link member 59 may have a guide portion 62. A guide rail 63 may be formed on the wall portion 60. The guide portion 62 is inserted into the guide rail 63. The guide portion 62 can move along the guide rail 63.

[0046] like Figure 2 As shown in FIG. 1 , when the moving motor 55 is driven to rotate forward with the cover 52 at the standby position P4, the slider 57 moves away from the moving motor 55. As a result, the cover 52 rises and moves to the entry position P5. The cover moving mechanism 53 moves the cover 52 from the standby position P4 to the entry position P5 by moving the cover 52 in the horizontal direction and the vertical direction.

[0047] like Figure 3 As shown, when the moving motor 55 is driven in reverse with the cover 52 located at the entry position P5, the slider 57 moves so as to approach the moving motor 55. As a result, the cover 52 is lowered and moved to the standby position P4.

[0048] like Figure 3 As shown, the cap 52 can cover the nozzle 35. When the cap 52 is located at the entry position P5, the nozzle 35 is covered. A portion of the cap 52 located at the entry position P5 is located in the cleaning space 65. The conveyor belt 40 located at the retreat position P2 is also located in the cleaning space 65.

[0049] like Figure 2 As shown, the cleaning space 65 is a space located below the conveyor belt 40 at the conveying position P1 in the vertical direction Z. In the drawing, the cleaning space 65 is indicated by a two-dot chain line. Foreign matter separated from the conveyor belt 40 is likely to accumulate in the cleaning space 65 .

[0050] The cleaning space 65 is a space for allowing displacement of the conveyor belt 40. The cleaning space 65 is a space for allowing movement of the cover 52. The cleaning space 65 is connected to the maintenance hole 19. When viewed from the front side of the device, at least a portion of the cleaning space 65 may overlap with the maintenance hole 19. The cover 52 located at the standby position P4 is offset from the cleaning space 65 in the width direction X. The displacement mechanism 30 that causes the conveyor belt 40 to be located at the conveying position P1 is offset from the cleaning space 65 in the depth direction Y.

[0051] <Control method of cleaning mode>

[0052] like Figure 2 As shown, the control unit 22 sets the conveyor belt 40 and the cover 52 to the first mode when recording on the medium 16. In the first mode, the conveyor belt 40 is located at the conveying position P1. In the first mode, the cover 52 is located at the standby position P4.

[0053] like Figure 3 As shown, the control unit 22 sets the conveyor belt 40 and the cover 52 to the second mode when the recording device 11 is in standby mode without recording on the medium 16, when the recording device 11 is in sleep mode, and when the power is turned off. In the second mode, the conveyor belt 40 is located at the retreat position P2. In the second mode, the cover 52 is located at the entry position P5.

[0054] like Figure 4 As shown, the control unit 22 sets the conveyor belt 40 and the cover 52 to the third mode when a paper jam occurs in which the medium 16 is blocked around the recording unit 25. In the third mode, the conveyor belt 40 is located at the processing position P3. In the third mode, the cover 52 is located at the standby position P4.

[0055] The control unit 22 can execute the cleaning mode. The control unit 22 can also receive an execution instruction of the cleaning mode from the outside. The control unit 22 can also execute the cleaning mode according to the received execution instruction. The user can instruct the execution of the cleaning mode from an external device (not shown) such as a personal computer, a smart phone, and a tablet computer. The user can also instruct the execution of the cleaning mode by operating the touch panel 14.

[0056] When recording on the medium 16, the counting unit 23 may also count the number of recorded sheets. When the counted number of recorded sheets reaches a predetermined number, the control unit 22 may also perform a notification to remind the execution of the cleaning mode. When the load of the driving unit 29 is greater than a threshold value, the control unit 22 may also perform a notification to remind the execution of the cleaning mode. The control unit 22 may cause the touch panel 14 to make a notification. The control unit 22 may also notify an external device.

[0057] The cleaning mode allows the cleaning space 65 to be cleaned from the outside when the opening and closing cover 18 is open. The cleaning mode is executed during standby or sleep mode. That is, before the cleaning mode is executed, the conveyor belt 40 is located at the retreat position P2 and the cover 52 is located at the entry position P5.

[0058] When the cleaning mode is executed, the control unit 22 sets the conveyor belt 40 and the cover 52 from the second mode to the first mode. That is, in the cleaning mode, the moving body 32 is moved from the entry position P5 included in the cleaning space 65 to the outside of the cleaning space 65. In the cleaning mode, the moving body 32 is moved from the entry position P5 included in the cleaning space 65 to a position not included in the cleaning space 65. In the cleaning mode, the moving body 32 is moved from the entry position P5 included in the cleaning space 65 to a space outside the cleaning space 65. In the cleaning mode, the cover 52 is located at the standby position P4. In the cleaning mode, the conveyor belt 40 is located at the conveying position P1. In the cleaning mode, the cleaning space 65 can be cleaned from the outside when the opening and closing cover 18 is opened. The cleaning space 65 can be cleaned from the maintenance hole 19. The cleaning of the cleaning space 65 can be performed, for example, by sucking foreign matter accumulated in the cleaning space 65 or wiping the foreign matter.

[0059] The control unit 22 may also terminate the cleaning mode when a predetermined time has passed since the cleaning mode was executed. The predetermined time may be a pre-set time or a time determined by the user. The detection unit 21 may also detect the open state and the closed state of the opening and closing cover 18 after the cleaning mode is executed. The control unit 22 may also terminate the cleaning mode when the detection unit 21 detects that the opening and closing cover 18 has shifted from the open state to the closed state after the cleaning mode is executed. The control unit 22 may also notify the end of the cleaning mode before terminating the cleaning mode.

[0060] When the cleaning mode is terminated, the control unit 22 sets the conveyor belt 40 and the cover 52 to the second state. That is, the control unit 22 moves the conveyor belt 40 to the retracted position P2. The control unit 22 moves the cover 52 to the advanced position P5.

[0061] <How to handle paper jams>

[0062] When clogging of the medium 16 occurs during recording, the control unit 22 stops recording. In other words, the control unit 22 stops driving of the driving unit 29 and discharging of the liquid from the liquid discharging head 34 .

[0063] When the conveyance detection unit 28 detects the medium 16 in the state where recording is stopped, the control unit 22 may also set the conveyor belt 40 and the cover 52 to the third mode. The control unit 22 changes from the first mode to the third mode. The cover 52 waits at the standby position P4. The conveyor belt 40 moves from the conveyance position P1 to the processing position P3. The conveyor belt 40 at the processing position P3 makes the supported medium 16 face the maintenance hole 19. In addition, the conveyor belt 40 at the processing position P3 is away from the static elimination unit 27. Therefore, the user can reduce the possibility of damage to the medium 16 and easily remove the medium 16 from the maintenance hole 19.

[0064] <Effects of Implementation Methods>

[0065] The operation of this embodiment will be described.

[0066] The moving body 32 at the entry position P5 is partially located in the cleaning space 65. When the cleaning mode is executed, the control unit 22 moves the moving body 32 to the standby position P4. The user can clean the cleaning space 65 while the moving body 32, which may become an obstacle when cleaning the cleaning space 65, is retreated from the cleaning space 65.

[0067] <Effects of Implementation Methods>

[0068] The effects of this embodiment will be described.

[0069] (1-1) The movable body 32 can move into and out of the cleaning space 65. When the movable body 32 is located in the cleaning space 65, the movable body 32 becomes an obstacle to cleaning. In this regard, when the control unit 22 executes the cleaning mode, the movable body 32 moves out of the cleaning space 65. Therefore, the workability of cleaning performed by the user can be improved.

[0070] (1-2) When the control unit 22 is instructed to execute the cleaning mode, it executes the cleaning mode. Therefore, the user can execute the cleaning mode at any timing.

[0071] (1-3) The accumulation of foreign matter increases in proportion to the number of recorded sheets. When the number of recorded sheets reaches a predetermined number, the control unit 22 performs a notification to prompt the user to execute the cleaning mode. Therefore, the user can clean the cleaning space 65 at a timing when cleaning is necessary.

[0072] (1-4) When foreign matter adheres to the driving unit 29, the load of the driving unit 29 may increase. When the load of the driving unit 29 exceeds the threshold, the control unit 22 performs a notification to remind the user to execute the cleaning mode. Therefore, the user can clean the cleaning space 65 at the timing when cleaning is required.

[0073] (1-5) Foreign matter separated from the conveyor belt 40 by cleaning the conveyor belt 40 is likely to accumulate under the conveyor belt 40. In this regard, the cleaning space 65 is located under the conveyor belt 40. Therefore, the space where foreign matter is likely to accumulate can be easily cleaned.

[0074] (1-6) In the standby state, cover 52 is located in cleaning space 65. However, control unit 22 moves cover 52 outside cleaning space 65 by executing the cleaning mode. Therefore, even when cleaning is performed in the standby state, cleaning work can be easily performed.

[0075] (1-7) The conveyor belt 40 and the cap 52 are located at the same position in the recording state and in the cleaning mode. Therefore, the mechanism can be simplified compared to a case where different positions are set in the recording state and in the cleaning mode.

[0076] (1-8) The movable body 32 includes the cover moving mechanism 53. The control unit 22 executes the cleaning mode to move the cover 52 and the cover moving mechanism 53 out of the cleaning space 65. Therefore, the cleaning work can be easily performed.

[0077] (1-9) When the cap 52 is located at the standby position P4, the liquid in the nozzle 35 is in a state that is easy to dry. In this regard, the control unit 22 moves the cap 52 to the entry position P5 when a predetermined time has passed after the cleaning mode is executed. That is, since the liquid ejection head 34 can be capped by the cap 52 moved to the entry position P5, the drying of the liquid can be reduced.

[0078] (1-10) The control unit 22 notifies the user of the end of the cleaning mode before a predetermined time has passed. Therefore, the user can be informed in advance that the cover 52 has been moved.

[0079] (1-11) The control unit 22 ends the cleaning mode when the opening and closing cover 18 is closed. Therefore, the user's workability can be improved compared to the case where the user performs the operation to end the cleaning mode.

[0080] (1-12) The cleaning unit 31 includes the scraper blade 50 . The scraper blade 50 can perform cleaning by scraping off foreign matter attached to the conveyor belt 40 .

[0081] (1-13) The opening and closing cover 18 is provided on the front side of the device. The user can efficiently perform cleaning work from the front side.

[0082] [Change example]

[0083] This embodiment can be implemented by changing the following. This embodiment and the following modified examples can be implemented in combination with each other within the range that there is no technical contradiction.

[0084] The opening and closing cover 18 may be provided at any position of the recording device 11.
