Sheet Feeding Tray 20

As illustrated in FIGS. 1 to 3, the sheet feeding tray 20 is provided at a lower portion of the image recording device 2. In the present embodiment, the sheet feeding tray 20 refers to the sheet feeding tray 20 including three types of trays. Specifically, the three types of trays included in the sheet feeding tray 20 include a multipurpose tray 21, a first tray 22 (an example of a second feeding tray, also referred to as a “PAPER TRAY 1”), and a second tray 23 (an example of a first feeding tray, also referred to as a “PAPER TRAY 2”). The multipurpose tray 21 refers to the sheet feeding tray 20 that is fixed to the housing 100 of the image recording device 2. The multipurpose tray 21 allows a plurality of cut sheets to be fed from a rear end side of the image recording device 2. The cut sheet is, for example, a sheet cut into a standard size (for example, A4). In FIG. 3, the second tray 23 is representatively shown as the sheet feeding tray 20.

The first tray 22 and the second tray 23 are trays that can be inserted into and extracted from the housing 100 (see FIG. 2) of the image recording device 2. The first tray 22 is a tray capable of accommodating the plurality of cut sheets. The second tray 23 is a tray including a first region 23A and a second region 23B capable of accommodating a sheet wound in a roll shape (hereinafter, also referred to as the roll sheet 46) and a plurality of cut sheets, respectively. The second tray 23 can be inserted into and extracted from the housing 100 of the image recording device 2 in the front-rear direction 8. As illustrated in FIGS. 2 and 3, the second tray 23 is a box having an opening on an upper surface. In the following description, the second tray 23 in which the roll sheet 46 is set is mainly described as a component of the sheet feeding tray 20. The extracted state of the sheet feeding tray 20 (the first tray 22 and the second tray 23) in the present disclosure may include a state in which the feeding tray 20 is completely extracted from the housing 100 or may include a state in which the feeding tray 20 is not completely extracted (that is, partially extracted) from the housing 100.

As illustrated in FIG. 3, the second tray 23 includes a bottom surface 11a that faces a main surface in the up-down direction 7 and has a rectangular outer shape in a planar view, and a front wall 11b, a left wall 11c, a right wall 11d, and a rear wall 11e which stand upward from four bottom sides. The rear wall 11e has an opening 27 penetrating the rear wall 11e in the front-rear direction 8. An outer shape of the opening 27 on the rear wall 11e in a side view is rectangular. A width of the rear wall 11e in the left-right direction 9 is larger than that of the roll sheet 46. As a result, the roll sheet 46 can pass through the opening 27 rearward. As illustrated in FIGS. 2 and 3, the second tray 23 includes a support base 81, a support plate 91, a passage 33, a protrusion 29, and side guides 30.

The support base 81 is provided at an end portion of the second tray 23 on the front side. The support base 81 has a rectangular parallelepiped shape in which an upper surface 81a is recessed, and both ends thereof in the left-right direction 9 are supported by side surfaces of the right wall 11d and the left wall 11c. A lower surface of the support base 81 is spaced from the bottom surface 11a of the second tray 23. A recess 82 recessed downward is provided on the upper surface 81a of the support base 81. An upper surface of the recess 82 is a circumferential surface recessed downward. A diameter of the upper surface of the recess 82 is larger than an outer diameter of the wound sheet (the roll sheet 46). In addition, the roll sheet 46 inserted from above is set in the recess 82. The roll sheet 46 is set on the upper surface of the recess 82. A mode of “setting” the roll sheet 46 includes, for example, a mode of “placing” the roll sheet 46 and a mode of rotatably “attaching” the roll sheet 46 to the multipurpose tray 21 or the like.

On the upper surface of the recess 82, a plurality of roller pairs are provided along the left-right direction 9. Each of the roller pairs includes a pair of rollers 83 separated from each other in the front-rear direction 8. Each of the rollers 83 is disposed such that an axial direction of each roller 83 extends along the left-right direction 9. An outer circumferential surface of each of the rollers 83 contacts an outer circumferential surface of the roll sheet 46. The pair of rollers 83 are located away from each other in the front-rear direction 8. A plurality of rollers 83 are located along the left-right direction 9. The rollers 83 rotate as the roll sheet 46 rotates.

A pull-out hole 84 is formed on the upper surface of the recess 82. The pull-out hole 84 extends to both ends of the support base 81 in the left-right direction 9. The pull-out hole 84 extends rearward and downward from the vicinity of a lowermost position on the upper surface of the recess 82, and extends from the upper surface of the recess 82 to the lower surface of the support base 81. An upper end of the pull-out hole 84 is located between the pair of rollers 83. The sheet pulled out from the roll sheet 46 is inserted through the pull-out hole 84. The pull-out hole 84 is a part of the passage 33 to be described later.

Support Plate 91

The support plate 91 is a plate that is provided between the rear of the support base 81 and the rear wall 11e. An outer shape of the support plate 91 in a planar view is substantially rectangular, and a central portion of a rear end portion in the left-right direction 9 is recessed forward to form a rectangular shape. At the rear end portion of the support plate 91, for example, a recess having an outer shape recessed in a rectangular shape from a rear end in a planar view is formed. Left and right ends of the support plate 91 are separated from the left wall 11c and the right wall 11d. The rear end of the support plate 91 is separated from the rear wall 11e. The lower surface of the support plate 91 is separated upward from the bottom surface 11a of the second tray 23. A front end of the support plate 91 is connected to a rear surface of the support base 81.

Passage 33

The passage 33 is formed between the lower surface of the support plate 91 and the bottom surface 11a of the second tray 23. The passage 33 extends from a second region 23B to the rear end of the support plate 91. Both ends in the left-right direction 9 and a rear end of the passage 33 are open. A front end of the passage 33 is a connection position between the pull-out hole 84 and the second region 23B. In the passage 33, the sheet inserted through the pull-out hole 84 from the roll sheet 46 reaches the rear of the support plate 91 through the passage 33.

A dimension of the support plate 91 in the left-right direction 9 is smaller than a dimension of the roll sheet 46 in the left-right direction 9. Left and right ends of the roll sheet 46 are located outside both ends of the support plate 91 in the left-right direction 9.

Protrusion 29

The protrusion 29 protrudes upward from the bottom surface 11a of the second tray 23. The protrusion 29 is provided at a rear end edge of the bottom surface 11a. For example, the protrusion 29 extends in the left-right direction 9 along a position of the opening 27 of the rear wall 11e. An upper surface of the protrusion 29 has, for example, a shape that allows the leading end of the sheet, which is fed (supplied) through the passage 33, to ride over. The upper surface of the protrusion 29 has, for example, an arch shape curved in the front-rear direction 8. In a conveyance direction of the roll sheet 46, the protrusion 29 is positioned on the downstream side of a position at which a feeding roller 32 is allowed to contact the roll sheet 46. That is, a state in which the leading end of the roll sheet 46 is positioned to contact the protrusion 29 means a state in which the leading end of the roll sheet 46 is positioned at a setting position at which the roll sheet 46 can be fed by the feeding roller 32. The user can understand that the leading end of the roll sheet 46 is set at the setting position not only by visually recognizing the leading end of the roll sheet 46 contacting the protrusion 29, but also by feeling an impact or hearing a sound caused by the leading end of the roll sheet 46 contacting (hitting) the protrusion 29.

Side Guides 30

Each side guide 30 is a plate whose main surface is oriented in the left-right direction 9. The pair of side guides 30 are located outside both ends of the support plate 91 in the left-right direction 9. Upper ends of the side guides 30 are at substantially the same positions as upper ends of the left wall 11c and the right wall 11d. The side guides 30 are movable in a direction approaching each other or a direction separating from each other along the left-right direction 9. The side guides 30 are moved along the left-right direction 9 in accordance with a width of the sheet in the left-right direction 9, and position the sheet in the left-right direction 9 by contacting left and right ends of the sheet. The pair of side guides 30 are mutually movable by, for example, a rack and pinion mechanism (not shown). The side guides 30 are moved to contact the sheet pulled out to the passage 33 from the roll sheet 46 set in the recess 82, for example.

The feeding roller 32 is axially supported by a tip end of an arm 2a. The arm 2a is rotatably supported by a support shaft 2b. The support shaft 2b is supported by the housing 100. The arm 2a is urged by an urging member (not shown) such that the feeding roller 32 approaches the bottom surface 11a of the sheet feeding tray 20. When the arm 2a rotates around the support shaft 2b, the feeding roller 32 rotates around an axis extending along the left-right direction 9 by driving of a conveying motor 120. The feeding roller 32 rotates to apply a conveying force in a direction from the front side to the rear side to the sheet in contact therewith. When the feeding roller 32 rotates, the sheet contacting the feeding roller 32 is fed in a backward direction (an example of a feeding direction).

Guide Piece 31

The guide piece 31 is a plate that is inclined such that an end portion on the rear side is located above an end portion on the front side. The guide piece 31 is provided on the rear side of the rear wall 11e of the second tray 23 and at the center in the left-right direction 9 when the second tray 23 is inserted into the housing 100. The sheet pulled out from the roll sheet 46 is guided obliquely upward along a surface of the guide piece 31.

Intermediate Roller Pair 41

The conveyance roller pair 42 includes a conveyance roller 42a that is rotated by the driving of the conveying motor 120, and a pinch roller 42b that is rotated together with the conveyance roller 42a. The conveyance roller pair 42 is provided downstream of the intermediate roller pair 41 in the conveyance direction 17. The conveyance roller pair 42 is provided on the upstream side of the discharge tray 24. The conveyance roller pair 42 nips the sheet conveyed by the intermediate roller pair 41 and conveys the sheet to a downstream side of the conveyance direction 17. The conveyance roller pair 42 conveys the sheet to the recording unit 6 provided on the downstream side of the conveyance direction 17.

Discharge Roller Pair 43

The discharge roller pair 43 includes a discharge roller 43a that is rotated by the driving of the conveying motor 120, and a pinch roller 43b. The conveyance roller pair 42 and the discharge roller pair 43 are provided above the sheet feeding tray 20 and are arranged from the rear side to the front side. The discharge roller pair 43 is provided in front of a head 39.

When the conveying motor 120 is driven under the control of the controller 10, the intermediate roller pair 41 rotates while nipping and holding the sheet therebetween, and conveys the sheet upward. The conveyance roller pair 42 is provided on the rear side of the head 39. The conveyance roller pair 42 nips and holds the sheet guided forward from above by the guide member 44, and conveys the sheet forward. The discharge roller pair 43 nips and holds the sheet recorded by the recording unit 6, and conveys the sheet forward toward the discharge tray 24. The conveyance roller pair 42 and the discharge roller pair 43 release the nipping when the first tray 22 is extracted. Specifically, the conveyance roller pair 42 and the discharge roller pair 43 release the nipping when the pinch rollers 42b and 43b move downward.

Cutter 5

As illustrated in FIGS. 2 and 4, the cutter 5 is provided between the guide piece 31 and the intermediate roller pair 41. The cutter 5 includes, for example, a disk-shaped rotary blade 74 and a driven blade 75. The rotary blade 74 is held by a cutter carriage 78 movable along the left-right direction 9. The cutter carriage 78 has left and right ends connected to the housing 100, and is movable in the left-right direction 9 by a rod-shaped carriage guide 80 extending in the left-right direction 9. The cutter carriage 78 is moved by driving of a cutting motor 130. The rotary blade 74 reciprocates as the cutter carriage 78 moves in the left-right direction 9. The sheet pulled out from the roll sheet 46 and conveyed is cut by the cutter 5 in a width direction (the left-right direction 9) when the cutting motor 130 is driven under the control of the controller 10. The cutter 5 moves, for example, from a start point position 76 (an example of a first position) to a turning point position 77 (an example of a second position) along the left-right direction 9, and then cuts the roll sheet 46 by reciprocating movement returning to the start point position 76.

The second cover 71 is provided on the rear side of the cutter 5. Specifically, the second cover 71 is provided on the rear side of the rotary blade 74.

A platen 47 that supports a lower surface of the sheet is provided below the nozzle surface 38.

Discharge Tray 24

In the housing 100, the discharge tray 24 is disposed in front of the head 39 and above the sheet feeding tray 20. As illustrated in FIG. 1, the discharge tray 24 can be accessed from the front of the housing 100. The discharge tray 24 can be extracted forward. When the discharge tray 24 is extracted forward, the pinch rollers 42b and 43b move downward. Accordingly, the contact between the pinch roller 42b and the conveyance roller 42a is released, and the contact between the pinch roller 43b and the discharge roller 43a is released. Therefore, the nipping between the conveyance roller 42a and the pinch roller 42b and between the discharge roller 43a and the pinch roller 43b is released.

First Registration Sensor 61

The first registration sensor 61 is provided between the guide piece 31 and the cutter 5 in the conveyance direction 17. The first registration sensor 61 is provided, for example, below the cutter 5 and above the guide piece 31. The first registration sensor 61 detects the presence or absence of the sheet moving from the sheet feeding tray 20 to the intermediate roller pair 41. The first registration sensor 61 detects the presence or absence of the sheet, for example, by detecting movement of a detector 61a that physically contacts the sheet by using an optical sensor 61b.

Second Registration Sensor 62

The second registration sensor 62 is provided between the intermediate roller pair 41 and the conveyance roller pair 42 in the conveyance direction 17. FIG. 2 shows an example in which the second registration sensor 62 is provided at the guide member 44. The second registration sensor 62 may, for example, be provided between the intermediate roller pair 41 and the guide member 44 in the conveyance direction 17. In this case, the second registration sensor 62 is provided above the intermediate roller pair 41 and below the guide member 44. The second registration sensor 62 detects the presence or absence of the sheet nipped by the intermediate roller pair 41 and moving toward the conveyance roller pair 42. The second registration sensor 62 detects the presence or absence of the sheet, for example, by detecting movement of a detector 62a that physically contacts the sheet by using an optical sensor 62b.

Media Sensor 63

The media sensor 63 is provided at the head 39 in the conveyance direction 17. The media sensor 63 is provided on the rear side of the head 39. The media sensor 63 detects the presence or absence of the sheet nipped by the conveyance roller pair 42 and moving toward the head 39.

Operation Panel 26

As illustrated in FIG. 1, the operation panel 26 is provided at the center of a front surface of the housing 100. The operation panel 26 is, for example, a push button such as a numeric keypad, and receives an operation input from the user who operates the image recording device 2. The operation panel 26 may be disposed to overlap the display 25, that is, may be combined with or integrated with a so-called touch panel.

Display 25

The display 25 is provided at the center of the front surface of the housing 100. For example, the display 25 is provided adjacent to the operation panel 26 in the left-right direction 9. The display 25 can visually display, for example, an operation state, a setting content, an error, and the like of the image recording device 2 to the user. In the present embodiment, when an abnormality in the sheet is detected, the display 25 displays an object display screen on which a target location for restoring the abnormality in the sheet to a normal state is displayed by using an object 176 (see FIG. 7A to FIG. 22D). The display 25 displays, for example, guidance data including the object display screen and a notification indicating occurrence of the abnormality in the sheet. The display 25 displays any one of a first guidance to a sixth guidance as the guidance data.

Controller 10

As illustrated in FIG. 5, the controller 10 includes a CPU 11, a ROM 12, a RAM 13, an EEPROM 14, and an ASIC 15, which are connected by an internal bus. The ROM 12 stores programs and the like for controlling various operations of the CPU 11. The RAM 13 is used as a storage area for temporarily storing data, signals, and the like to be used when the CPU 11 executes the programs described above, or as a work area for data processing. The EEPROM 14 stores settings, flags, and the like to be held even after a power supply is turned off.

The conveying motor 120 and the cutting motor 130 are connected to the ASIC 15. The ASIC 15 generates a drive signal for causing each motor to rotate, and controls each motor based on the drive signal. Each motor rotates forward or backward according to the drive signal from the ASIC 15. The controller 10 controls the driving of the conveying motor 120 to drive the feeding roller 32, the drive roller 41a, the conveyance roller 42a, and the discharge roller 43a. The controller 10 controls the driving of the cutting motor 130 to drive the cutter 5 (the cutter carriage 78 and the rotary blade 74).

The display 25 and the operation panel 26 are connected to the ASIC 15. The display 25 displays the operation state, the setting content, the first guidance to the sixth guidance, and the like of the image recording device 2. The operation panel 26 outputs an operation signal corresponding to an operation by the user to the controller 10.

The first registration sensor 61, the second registration sensor 62, the media sensor 63, the discharge sensor 64, the start point sensor 65, and the turning point sensor 66 are electrically connected to the ASIC 15. The controller 10 detects the arrival of the sheet to the first registration sensor 61 via the first registration sensor 61. The controller 10 detects the arrival of the sheet to the second registration sensor 62 via the second registration sensor 62. The controller 10 detects the arrival of the sheet to the media sensor 63 via the media sensor 63. The controller 10 detects the arrival of the sheet to the discharge sensor 64 via the discharge sensor 64. The controller 10 detects the arrival of the cutter carriage 78 to the start point position 76 via the start point sensor 65. The controller 10 detects the arrival of the cutter carriage 78 to the turning point position 77 via the turning point sensor 66.

The EEPROM 14 stores the guidance data including different object display screens depending on a detection position of the sheet and a position of the cutter carriage 78, and the notification indicating the occurrence of the abnormality in the sheet. The guidance data includes the first guidance to the sixth guidance. The EEPROM 14 stores, as the guidance data, the first guidance to the sixth guidance each including a plurality of object display screens with a predetermined display order.

The occurrence of the abnormality in the sheet is, for example, occurrence of a conveyance abnormality (a conveyance jam) of the sheet and a cutting abnormality due to the cutter 5. The conveyance abnormality of the sheet is, for example, a jam of sheet in the feeding roller 32, the intermediate roller pair 41, the conveyance roller pair 42, or the discharge roller pair 43. The cutting abnormality is, for example, one or both of the fact that the cutter 5 is driven but the sheet cannot be cut and the fact that the cutter 5 (the rotary blade 74) cannot return to the start point position 76.

The location indicated as the object 176 on the object display screen is a component to be operated or checked by the user among the components of the image recording device 2. Examples of the location include a sheet feeding portion, a cutter portion, a rear cover portion, and a discharge portion. The sheet feeding portion includes the first tray 22, the second tray 23, and the like. The cutter portion includes the cutter 5 (the rotary blade 74), the second cover 71, and the like. The rear cover portion includes the first cover 70 and the like. The discharge portion includes the discharge tray 24 and the like.

The user operates the components of the image recording device 2 in accordance with the guidance data displayed on the display 25 to remove the sheet causing the conveyance jam. Further, when the user manually operates the cutter 5 of the image recording device 2, the rotary blade 74 of the cutter 5 returns to the start point position 76. When such the work is completed, the abnormality in the sheet returns to the normal state. The description “returns to the normal state” means returning to a state in which a new image can be recorded on a sheet by removing the sheet from a portion between the sheet feeding tray 20 and the discharge tray 24 (the conveyance path 18).

Guidance Display Operation by Image Recording Device 2

Next, a guidance display operation by the image recording device 2 will be described.

As illustrated in FIG. 6, the controller 10 starts the conveyance of the sheet pulled out from the roll sheet 46 from the second tray 23. The controller 10 drives the conveying motor 120 to rotate the feeding roller 32, the intermediate roller pair 41, the conveyance roller pair 42, and the discharge roller pair 43 (step S1).

Next, the controller 10 determines whether the sheet passes through the first registration sensor 61 within a predetermined time (step S2). The controller 10 determines whether the sheet passes through the first registration sensor 61 based on a signal obtained from the first registration sensor 61. When the first registration sensor 61 detects the passage of the sheet within the predetermined time (step S2_YES), the process proceeds to step S3. When the first registration sensor 61 does not detect the passage of the sheet within the predetermined time (step S2_NO), the process proceeds to step S11.

In step S3, the controller 10 determines whether the sheet passes through the second registration sensor 62 within a predetermined time. The controller 10 determines whether the sheet passes through the second registration sensor 62 based on a signal obtained from the second registration sensor 62. When the second registration sensor 62 detects the passage of the sheet within the predetermined time (step S3_YES), the process proceeds to step S4. When the second registration sensor 62 does not detect the passage of the sheet within the predetermined time (step S3_NO), the process proceeds to step S13.

In step S4, the controller 10 determines whether the sheet passes through the media sensor 63 within a predetermined time. The controller 10 determines whether the sheet passes through the media sensor 63 based on a signal obtained from the media sensor 63. When the media sensor 63 detects the passage of the sheet within the predetermined time (step S4_YES), the process proceeds to step S5. When the media sensor 63 does not detect the passage of the sheet within the predetermined time (step S4_NO), the process proceeds to step S6.

In step S5, the controller 10 determines whether the sheet passes through the discharge sensor 64 within a predetermined time. The controller 10 determines whether the sheet passes through the discharge sensor 64 based on a signal obtained from the discharge sensor 64. When the discharge sensor 64 detects the passage of the sheet within the predetermined time (step S5_YES), the process proceeds to step S19. When the discharge sensor 64 does not detect the passage of the sheet within the predetermined time (step S5_NO), the process proceeds to step S6.

In step S6, the controller 10 stops the conveying motor 120. Accordingly, the conveyance of the sheet is stopped. In this state, it is considered that although the sheet passes through the recording unit 6, the paper jam occurs before the sheet reaches the discharge roller pair 43. That is, the sheet is nipped by the intermediate roller pair 41 and the conveyance roller pair 42. Thereafter, the process proceeds to step S7.

In step S7, the controller 10 drives the cutter carriage 78 to cut the sheet. For example, the controller 10 drives the cutting motor 130 to move the cutter carriage 78 from the start point position 76 to the turning point position 77 and then return the cutter carriage 78 to the start point position 76. In step S7, the controller 10 may execute cutting of the sheet in response to a command input to the operation panel 26.

Next, the controller 10 determines whether the cutting is completed (step S8). The controller 10 drives the cutter carriage 78 and obtains signals output from the start point sensor 65 and the turning point sensor 66. The controller 10 determines whether the cutter carriage 78 can be moved from the start point position 76 to the turning point position 77 based on the obtained signals. When a signal indicating the detection of the cutter carriage 78 cannot obtained from the turning point sensor 66, the controller 10 determines that the sheet is not successfully cut. This indicates that the cutter carriage 78 cannot cross the sheet in the left-right direction 9 and the sheet is not successfully cut. When the cutting is completed (step S8_YES), the process proceeds to step S9. When the cutting is not completed (step S8_NO), the process proceeds to step S15.

In step S9, the controller 10 determines whether the cutter carriage 78 is returned to a start point. The controller 10 obtains a signal output from the start point sensor 65. The controller 10 determines whether the cutter carriage 78 can be detected again based on the output of the start point sensor 65. When the cutter carriage 78 is detected again (step S9 YES), the process proceeds to step S10. When the cutter carriage 78 is not detected (step S9 NO), the process proceeds to step S18.

In step S10, the controller 10 reads the third guidance from the EEPROM 14 and displays the third guidance on the display 25. Details of the third guidance will be described later. Accordingly, the process according to this flow ends.

In step S11, the controller 10 stops the conveying motor 120. Accordingly, the conveyance of the sheet is stopped. In this state, it is considered that the sheet does not reach the intermediate roller pair 41 and the paper jam occurs. That is, the sheet is not nipped by any roller. Thereafter, the process proceeds to step S12.

In step S12, the controller 10 reads the first guidance from the EEPROM 14 and displays the first guidance on the display 25. Details of the first guidance will be described later. Accordingly, the process according to this flow ends.

In step S13, the controller 10 stops the conveying motor 120. Accordingly, the conveyance of the sheet is stopped. In this state, it is considered that although the sheet passes through the intermediate roller pair 41, the paper jam occurs before the sheet reaches the conveyance roller pair 42. That is, the sheet is nipped by the intermediate roller pair 41. Thereafter, the process proceeds to step S14.

In step S14, the controller 10 reads the second guidance from the EEPROM 14 and displays the second guidance on the display 25. Details of the second guidance will be described later. Accordingly, the process according to this flow ends.

In step S15, the controller 10 determines whether the cutter carriage 78 is returned to the start point position 76. The controller 10 obtains a signal output from the start point sensor 65. The controller 10 determines whether the cutter carriage 78 can be detected again based on the output of the start point sensor 65. When the cutter carriage 78 is detected again (step S15 YES), the process proceeds to step S16. When the cutter carriage 78 is not detected (step S15 NO), it is considered that the cutter carriage 78 does not return to the start point position 76. The process proceeds to step S17.

In step S16, the controller 10 reads the fifth guidance from the EEPROM 14 and displays the fifth guidance on the display 25. Details of the fifth guidance will be described later. Accordingly, the process according to this flow ends.

In step S17, the controller 10 reads the sixth guidance from the EEPROM 14 and displays the sixth guidance on the display 25. Details of the sixth guidance will be described later. Accordingly, the process according to this flow ends.

In step S18, the controller 10 reads the fourth guidance from the EEPROM 14 and displays the fourth guidance on the display 25. Details of the fourth guidance will be described later. Accordingly, the process according to this flow ends.

In step S19, the controller 10 drives the cutting motor 130 to cut the sheet. Accordingly, this flow ends without the occurrence of the abnormality in the sheet.

First Guidance

The first guidance includes an object display screen indicating, by the object 176, the target location of the image recording device 2 for dealing with the paper jam before the sheet reaches the intermediate roller pair 41. As illustrated in FIG. 7A to FIG. 22D, a title 178 (an example of the notification) is displayed in an upper portion of the object display screen for each of the following guidances. An image showing the object 176 is displayed on the left side of the object display screen. Below the image showing the object 176, arrow icons 169 for switching screens are shown. A text 177 describing an operation content is displayed on the right side of the object display screen. Below the text 177 describing the operation content, a page number and a “x” icon 167 are shown. For example, the controller 10 switches the respective screens by selecting and executing the arrow icons 169 shown at a lower left corner of each screen with the operation panel 26. On the left side of each screen, an object image including the object 176 indicating a work target portion is shown. Further, the controller 10 ends the guide according to each guidance by selecting and executing the “x” icon 167 shown at a lower right corner of each screen with the operation panel 26. According to the first guidance, the text “paper jam [roll] 01” is displayed as the title 178. In the following description of each guidance, to perform a work in accordance with the object 176 displayed on each object screen until the “x” icon 167 shown at the lower right corner of each screen is selected and executed with the operation panel 26 corresponds to a “restoring work to the normal state”.

As illustrated in FIG. 7A, on the left side of a screen 181, an image including the housing 100 and PAPER TRAY 2 detached from the housing 100 is shown as the object 176. On the right side thereof, the text 177 “detach paper tray 2” is shown. Accordingly, on the screen 181, the user is guided to extract the second tray 23 from the housing 100.

As illustrated in FIG. 7B, on the left side of a screen 182 shown next to the screen 181, an image including a perspective view of PAPER TRAY 2 and roll paper unloaded upward from PAPER TRAY 2 is shown as the object 176. On the right side thereof, the text 177 “roll up and unload roll paper” is shown. Accordingly, on the screen 182, the user is guided to roll up the roll sheet 46 and unload the roll sheet 46 from the detached second tray 23.

As illustrated in FIG. 7C, on the left side of a screen 183 shown next to the screen 182, an image including a perspective view of the roll paper and a leading end of the roll paper to be cut by using scissors is shown as the object 176. On the right side thereof, the text 177 “cut leading end of sheet at right angle when leading end of sheet is folded or inclined” is shown. Accordingly, on the screen 183, the user is guided to cut the leading end of the unloaded roll sheet 46 in order to adjust the leading end.

As illustrated in FIG. 7D, on the left side of a screen 184 shown next to the screen 183, an image including the perspective view of PAPER TRAY 2 and the roll paper set in PAPER TRAY 2 is shown as the object 176. On the right side thereof, the text 177 “set sheet” is shown. Accordingly, on the screen 183, the user is guided to reset the roll sheet 46 whose leading end is cut in the second tray 23.

As illustrated in FIG. 7E, on the left side of a screen 185 shown next to the screen 184, an image including the perspective view of PAPER TRAY 2, the roll paper whose leading end is pulled out, and a mark for rotating the roll paper is shown as the object 176. On the right side thereof, the text 177 “rotate roll paper to advance leading end of sheet” is shown. Accordingly, on the screen 185, the user is guided to pull out the leading end of the roll sheet 46 to the passage 33 on the second tray 23.

As illustrated in FIG. 7F, on the left side of a screen 186 shown next to the screen 185, an image including a planar view of a rear end side of PAPER TRAY 2 and the leading end of the roll paper pulled out to a rear end of PAPER TRAY 2 is shown as the object 176. On the right side thereof, the text 177 “confirm that leading end of sheet contacts end of tray” is shown. Accordingly, on the screen 186, the user is guided to bring the leading end of the sheet pulled out from the roll sheet 46 into contact with the protrusion 29 on the second tray 23. In the present embodiment, the protrusion 29 serves as an example of a position indicating the setting position of the leading end of the roll sheet 46 when the roll sheet 46 is set in the second tray 23. That is, by setting the leading end of the roll sheet 46 to contact the protrusion 29, the roll sheet 46 is ready to be fed and conveyed by the feeding roller 32. The screen 186 indicates that the leading end of the roll sheet 46 has been set at a position which allows the roll sheet to be fed and conveyed. The user can understand that the leading end of the roll sheet 46 is set at the setting position not only by visually recognizing the leading end of the roll sheet 46 contacting the protrusion 29, but also by feeling an impact or hearing a sound caused by the leading end of the roll sheet 46 contacting (hitting) the protrusion 29. The setting position indicated in the screen 186 of the present disclosure is not limited to the protrusion 29, and may be any position which allows the roll sheet 46 to be fed and conveyed, that is, a position at which the feeding roller 32 is allowed to contact the roll sheet or a position on the downstream side thereof in the conveyance direction of the roll sheet 46.

As illustrated in FIG. 8A, on the left side of a screen 187 shown next to the screen 186, an image including the perspective view of PAPER TRAY 2, the set roll paper, and a mark for operating a sheet guide is shown as the object 176. On the right side thereof, the text 177 “adjust sheet guide” is shown. Accordingly, on the screen 187, the user is guided to move, on the second tray 23, the side guides 30 to contact left and right ends of the sheet pulled out from the roll sheet 46.

As illustrated in FIG. 8B, on the left side of a screen 188 shown next to the screen 187, an image including the perspective view of PAPER TRAY 2 and a perspective view of the housing 100 is shown as the object 176. On the right side thereof, the text 177 “1. reset paper tray 2; 2. press stop x” is shown. Accordingly, on the screen 188, the user is guided to attach the second tray 23 to the housing 100. Accordingly, the guide according to the first guidance ends.

Second Guidance

The second guidance includes an object display screen indicating, by the object 176, the target location of the image recording device 2 for dealing with the paper jam before the sheet passes through the conveyance roller pair 42 after the sheet reaches the intermediate roller pair 41. According to the second guidance, the text “paper jam [roll] 02” is displayed as the title 178 (the example of the notification).

As illustrated in FIG. 9A, on the left side of a screen 189, an image including REAR COVER A to be opened and a rear surface of the image recording device 2 is shown as the object 176. On the right side thereof, the text 177 “open rear cover A; perform work while maintaining cover open until instruction is issued” is shown. Accordingly, on the screen 189, the user is guided to open the first cover 70 and release the nipping of the sheet by the intermediate roller pair 41.

As illustrated in FIG. 9B, on a screen 190 shown next to the screen 189, the object 176 and the text 177 having the same contents as those of the screen 181 are shown. Accordingly, on the screen 190, the user is guided to extract the second tray 23 from the housing 100.

Modifications

The controller 10 may drive the cutting motor 130 when the power supply of the image recording device 2 is turned on. When the cutter carriage 78 moves from the start point position 76 to the turning point position 77 and cannot return to the start point position 76, the controller 10 may display, on the display 25, an object display screen for manually returning the cutter carriage 78 to the start point position 76.

In addition, in the embodiment described above, the roll sheet 46 may be obtained by winding paper, a cloth, or a film.

Further, the roll sheet 46 is set in PAPER TRAY 2, but the present disclosure is not limited thereto. The roll sheet 46 may be set in the multipurpose tray 21. Regarding the roll sheet 46, the roll sheet 46 may be held (set) in a tray prepared separately from the housing 100 of the image recording device 2. The separately prepared tray may not be attached to the image recording device 2. Positions of the cutter carriage 78 and the intermediate roller pair 41 may be appropriately changed in accordance with a position of the roll sheet 46 set in the multipurpose tray 21.

Further, the side guides 30 may contact the left and right ends of the roll sheet 46 set in the recess 82.

In addition, in the embodiment described above, the media sensor 63 is set as the third sensor, but the present disclosure is not limited thereto. The third sensor may be, for example, the discharge sensor 64.

In the embodiment described above, the controller 10 may change a content of the notification of the conveyance jam, which is displayed on the display 25, depending on whether the conveyance jam is caused by the cut sheet fed from the first tray 22 or whether the conveyance jam is caused by the roll sheet 46 fed from the second tray 23. For example, the controller 10 may change the content of the notification of the conveyance jam, which is displayed on the display 25, based on information for identifying the sheet feeding tray 20 (the first tray 22 or the second tray 23) used for sheet feeding and the detection of the abnormality in the sheet. For example, the controller 10 may display “sheet jam” on the object display screen displayed on the display 25 based on information indicating that the first tray 22 is used for the sheet feeding and the detection of the abnormality. In addition, for example, the controller 10 may display “sheet jam (roll)” on the object display screen displayed on the display 25 based on information indicating that the second tray 23 is used for the sheet feeding and the detection of the abnormality.

In the embodiment described above, the controller 10 may execute a confirmation operation of checking whether the image recording device 2 is returned to the normal state after the display of the guidance data on the display 25 is completed. For example, the controller 10 may check whether an operation of each component of the image recording device 2 is in a normal state according to the selection and execution of the “x” icon 167 at the time of the ending of each guidance. Further, the controller 10 may display, on the display 25, a confirmation result of the operation of each component (whether the component is returned to the normal state). When the confirmation of the operation of each component by the controller 10 is normally completed, the operation of the image recording device 2 is returned to the normal state.
