[0008] Preferred embodiments of this disclosure will be described below with reference to the drawings. While specific details may be provided in the embodiments described below for the sake of clarity, these are merely technically preferred examples and are not intended to unnecessarily limit the scope of this disclosure. For example, the dimensions, materials, shapes, and relative arrangements of the components described in the embodiments below are not intended to limit the scope of this disclosure unless otherwise specified.

[0009] <Recording device> The configuration of the recording device in this disclosure will be described below with reference to Figures 1 and 2. While a multifunction printer will be used as an example of a recording device in this description, the technology of this disclosure can be applied to any device that ejects liquids such as ink to record images onto a recording medium (hereinafter referred to as "the medium") such as paper. Examples of such devices include inkjet printers and other (image) recording devices, as well as fax machines.

[0010] As shown in Figure 1, the multifunction printer 11 comprises a rectangular parallelepiped-shaped main unit 12, an image reading unit 13 located on the upper part of the main unit 12, and an automatic document feeding unit 14 located above the image reading unit 13. The main unit 12 also serves as the main part of the printer unit 15. The multifunction printer 11 has a configuration in which the printer unit 15, the image reading unit 13, and the automatic document feeding unit 14 are stacked on top of each other in the vertical direction Z, from bottom to top. The main unit 12 has a transport path T (see T1 to T11 in Figure 2) for transporting a medium M such as paper. The multifunction printer 11 is installed on a mounting surface F with multiple casters 16 provided on the bottom of the main unit 12 touching the ground.

[0011] The image reading unit 13 is configured to read images such as text and photographs recorded on the original document D (shown by a dashed line in Figure 1). The automatic document feeding unit 14 has a document tray 17 on which the original document D can be placed. The automatic document feeding unit 14 feeds the original document D placed on the document tray 17 toward the image reading unit 13. After being read by the image reading unit 13, the original document D is discharged into the output tray 18. The automatic document feeding unit 14 also serves as the document tray cover for the image reading unit 13 and is provided so as to be openable and closable relative to the image reading unit 13. When the automatic document feeding unit 14 is opened, the document tray (not shown) located on the top surface of the image reading unit 13 is exposed. After placing the original document on the document tray, the automatic document feeding unit 14 is closed. The image reading unit 13 is capable of reading the original document placed on the document tray.

[0012] Furthermore, an operation panel 19 is provided on the upper part of the main unit 12 of the device, which is operated when giving instructions to the multifunction printer 11. The operation panel 19 has a display unit 19A. The display unit 19A has a screen, for example, consisting of a touch panel. A touch panel is a display panel that allows instructions to be given to the multifunction printer 11 by touching the screen. The operation panel 19 may have buttons for operation, or it may consist only of buttons for operation without a display unit 19A.

[0013] The multifunction printer 11 is equipped with a cassette 20 (media storage section) for holding multiple media M. Multiple media M are stored in the cassette 20. The cassette 20 is a paper feed cassette capable of storing paper as an example of media M. The multifunction printer 11 has a total of four cassettes 20. The four cassettes 20 are arranged in four layers at the bottom of the device body 12, overlapping in the vertical Z direction. Multiple cassettes 20 are mounted on the device body 12 in a removable manner. The cassettes 20 are configured to be pullable out in the Y-axis direction relative to the device body 12. Multiple cassettes 20 can hold media M of different sizes or paper types, for example.

[0014] As shown in Figure 1, each cassette 20 has a cassette cover 20K facing the Y-axis direction. This cassette cover 20K is an example of a cover that can be opened and closed relative to the device body 12, and is provided on the side surface 12F of the device body 12 facing the Y-axis direction. For improved usability, the direction in which the side surface 12F on which the cassette cover 20K is provided faces is the same as the direction in which the operation panel 19 of the multifunction printer 11 faces. The cassette cover 20K is provided on the cassette 20 which can be pulled out in the Y-axis direction. The cassette cover 20K is also provided with a handle 20E for the user to pull out the cassette 20.

[0015] Furthermore, the number of cassettes 20 can be set arbitrarily. The number of cassettes 20 is not limited to 4; it may be 2, 3, 5, 6 or more. In addition, a multi-story cassette 20 may be composed of an optional expansion unit in which some of the cassettes are added. For example, the multifunction printer 11 may have a standard configuration with 2 cassettes 20, and the user may optionally add an expansion unit with 2 cassettes 20. The expansion unit may also be configured to allow for the addition of cassettes 20 one at a time.

[0016] As shown in Figures 1 and 2, the side surface 12S of the main body 12 of the device is provided with a cover CV that can switch between a first state in which the transport path T (see Figure 2) is exposed and a second state in which the transport path T is covered. The cover CV is divided into a first cover 21 and a second cover 22.

[0017] In other words, the side surface 12S is provided with a first cover 21 and a second cover 22 located below the first cover 21, both of which can be opened and closed relative to the device body 12. Furthermore, the side surface 12S is provided with a third cover 23 located below the second cover 22, which can be opened and closed relative to the device body 12.

[0018] The first cover 21 is larger than the second cover 22. That is, the first cover 21 occupies a larger area (occupied area) on the side surface 12S than the second cover 22. The first cover 21 has a handle 21A for the user to open and close it. The first cover 21 also includes a feed tray 24 as an example of a tray for placing the medium M. The feed tray 24 is attached to the first cover 21 in a manner that allows it to be opened and closed. The feed tray 24 has a handle 24A.

[0019] The second cover 22 and the third cover 23 are approximately the same size and shape. The second cover 22 has a handle 22A for the user to open and close it. The third cover 23 also has a handle 23A for the user to open and close it. The second cover 22 and the third cover 23 have the handles 22A and 23A at approximately the same position on each cover surface (upper left position in Figure 1). In this example, the first cover 21, the second cover 22, and the third cover 23 allow most of the side surface 12S to be opened and closed.

[0020] Furthermore, as shown in Figure 1, a front cover 25 that can be opened and closed is provided on the front of the device body 12 in the upper right area of ​​the cassette 20. Here, "front" refers to the surface that the user faces when performing basic operations, and is the surface on which the operation panel 19 and the cassette cover 20K are located. The front cover 25 can be opened and closed by swinging it sideways with its right end as the pivot point. Note that the second cover 22 and the third cover 23 may differ in at least one of their size and shape. Alternatively, in Figure 1, the third cover 23 may be omitted, and the second cover 22 may be made of a single cover having the combined size of the second cover 22 and the third cover 23 shown in Figure 1.

[0021] Furthermore, as shown in Figure 1, the device body 12 has a recording unit 30 that records on a medium M (see Figure 2). The recording unit 30 records on medium M supplied from the cassette 20 and medium M supplied from the supply tray 24. Inside the device body 12 is a liquid supply source 35 (see Figure 2) that contains ink as an example of a liquid. The recording unit 30 records on the medium M using a liquid such as ink supplied from the liquid supply source 35. As shown in Figure 1, a window 26 is provided on the front of the device body 12 in an area corresponding to the liquid supply source 35. The user can visually check the remaining amount of liquid in the liquid supply source 35 through the window 26.

[0022] A concave mounting section 31 is provided between the main body 12 of the device and the image reading unit 13. The mounting section 31 includes a discharge tray 32 that forms its bottom. The discharge tray 32 is a plate-shaped member, and the discharged media M is stacked on the upper surface of the discharge tray 32. The discharge tray 32 is inclined at a predetermined angle such that the downstream side in the discharge direction from which the recorded media M is discharged is higher than the upstream side. The main body 12 has a discharge port 71 (Figure 8) that opens into one of the side walls (right side wall) that forms the concave part of the mounting section 31. The recorded media M is discharged from the discharge port 71 and stacked on the discharge tray 32 of the mounting section 31. The media M discharged onto the discharge tray 32 descends along the slope due to its own weight and hits a regulating wall (not shown), thereby aligning the upstream end in the discharge direction.

[0023] As shown in Figure 2, when viewing the mounting section 31 from the Y direction, the diagonal direction in which the discharge tray 32 extends is defined as direction B. Of the B directions, the direction having a component in the +Z direction is defined as the +B direction, and the direction having a component in the -Z direction is defined as the -B direction. Furthermore, the direction perpendicular to direction B that forms the slope of the discharge tray 32 is defined as direction C. Of the C directions, the direction having a component in the +Z direction is defined as the +C direction, and the direction having a component in the -Z direction is defined as the -C direction.

[0024] <Printer Unit Configuration> The detailed configuration of the printer unit 15 shown in Figure 1 will be explained below with reference to Figure 2. The main body of the device 12 is provided with a transport unit 40 that transports the medium M along the transport path T, and a recording unit 30 that records on the medium M. Furthermore, it is provided with a medium width sensor 33 that detects the medium M being transported along the transport path T, a liquid supply source 35 that supplies liquid such as ink to the recording unit 30, a waste liquid storage unit 36 ​​that stores waste liquid such as ink, and a control unit 37 that controls the operation of each part of the multifunction printer 11.

[0025] The recording unit 30 includes a liquid ejection head 30A that ejects a liquid such as ink onto the medium M. The liquid ejection head 30A ejects a liquid such as ink, supplied from a liquid supply source 35 through a tube (not shown), from a nozzle (not shown). The liquid supply source 35 may be a replaceable liquid cartridge such as an ink cartridge, or a liquid tank that can be refilled with liquid such as an ink tank.

[0026] In the example shown in Figure 2, the liquid ejection head 30A is positioned at an angle to the horizontal. That is, the nozzle surface of the liquid ejection head 30A, from which the liquid ejection nozzle opens, is positioned at an angle to the horizontal. The liquid ejection head 30A faces the conveyor belt 48. The liquid ejection head 30A ejects liquid onto the medium M being conveyed along the conveying direction A on the conveyor belt 48. The angle at which the liquid ejection head 30A is tilted relative to the horizontal can be changed as appropriate. For example, the liquid ejection head 30A and the conveyor belt 48 may be positioned horizontally (tilt angle 0°). The recording unit 30 may also be configured to include recording heads other than the liquid ejection head 30A that ejects liquid. Other recording heads may include dot impact recording heads, thermal recording heads, or, for example, laser recording heads that record with toner.

[0027] The conveying unit 40 is equipped with a plurality of rollers and the like, provided along the conveying path T. Specifically, the conveying unit 40 has a feed roller 41 and a pair of separation rollers 42 for the cassette 20, and a feed roller 43 and a separation roller 44 for the feed tray 24. The conveying unit 40 also has conveying roller pairs 45-47, 54-56 of the conveying system, discharge roller pairs 49, 51, 53, conveying rollers 61-64, and an incoming roller 65. The conveying path T includes the first to sixth conveying paths T1-T6, which are the conveying paths of the feeding system, and the seventh to ninth conveying paths T7-T9 and reversing paths T10, T11, which are the conveying paths of the conveying system. In this specification, when individual conveying paths T1-T11 etc. are not specifically distinguished or are referred to collectively, they may simply be written as conveying path T. This notation rule shall also apply similarly to other components.

[0028] More specifically, a feed roller 41 and a pair of separation rollers 42 are provided for each of the multiple cassettes 20 mounted on the main body 12 of the device, near the downstream end in the feeding direction of each cassette 20. The multiple media M contained in the cassette 20 are placed on a mounting plate 20F that is biased towards the +Z side (upwards), with the downstream portion in the feeding direction being placed on the mounting plate 20F. The mounting plate 20F is rotatably mounted on the main body 12 of the cassette 20, and biases the media M towards the +Z side, lifting it upwards as it moves downstream in the feeding direction. The uppermost media M of the multiple media M placed on the mounting plate 20F is pressed against the feed roller 41. As the feed roller 41 rotates in this state, the uppermost media M is fed out in the feeding direction. The fed-out media M is then separated by the separation action of the pair of separation rollers 42, which rotates while nipped at the separation rollers 42, and only one media M is separated and fed downstream. The media M supplied from each cassette 20 is transported along the transport paths T1 to T4 towards the +Z side and reaches the transport path T7. The media M supplied from the cassette 20 is transported towards the downstream transport path T7 by transport rollers 61 to 64 provided along each transport path T1 to T4.

[0029] As shown in Figure 2, the feeding tray 24 is equipped with edge guides 24B for positioning the placed medium M in the width direction. The first cover 21 is equipped with feeding rollers 43 for feeding the medium M placed on the feeding tray 24 to the transport path T. The first cover 21 is also equipped with separation rollers 44 that rotate in contact with the feeding rollers 43. The transport path T5, through which the medium M is transported from the feeding tray 24 by the feeding rollers 43 and separation rollers 44, merges with the transport path T7.

[0030] Furthermore, there is a transport path T6 for loading the medium M from the loading entrance (not shown) of the second cover 22. The transport path T6 is a transport route used when the medium M is loaded into the multifunction printer 11 from an external device. The second cover 22 is provided with loading rollers 65 for loading the medium M from the loading entrance along the transport path T6. In addition, the transport rollers 61 also serve as transport rollers for transporting the medium M along the transport path T6. The medium M loaded from the transport path T6 merges with the transport path T7 downstream.

[0031] As shown in Figure 2, the transport path T7 is curved in the region facing the medium width sensor 33 and extends diagonally upward from the medium width sensor 33. The medium M is transported along the transport path T7 to the recording position RP facing the liquid ejection head 30A by the rotation of the transport roller pairs 45, 46, and 47. At the recording position RP, the medium M is transported on a transport belt 48 positioned opposite the liquid ejection head 30A. The liquid ejection head 30A records on the medium M as it is transported on the transport belt 48. The liquid ejection head 30A is, for example, an inkjet recording method that ejects a liquid such as ink. At the recording position RP, the medium M is transported in direction A. After recording is complete, the medium M is transported downstream by the discharge roller pair 49. A flap 50 is provided downstream of the discharge roller pair 49. The flap 50 distributes the medium M to the transport path T8 and the reversal path T10.

[0032] In the case of single-sided recording, where recording is done on only one side of the medium M, after recording on the first side, the medium M is directed to the transport path T8 by the flap 50. The medium M directed to the transport path T8 is then transported downstream by the discharge roller pair 51. On the other hand, in the case of double-sided recording, where recording is done on both sides of the medium M, after recording on the first side, the medium M, having completed single-sided recording, is directed from the transport path T7 to the reversal path T10 by the flap 50.

[0033] Furthermore, a flap 52 is provided in the middle of the transport path T8. The flap 50 distributes the medium M to the transport path T8 and the transport path T9. The medium M transported along the transport path T8 is discharged onto the discharge tray 32 of the mounting section 31. The medium M distributed to the transport path T9 is discharged to the mounting section 31 by a pair of discharge rollers 53 provided along the transport path T9, and then discharged onto an unshown discharge tray provided in the mounting section 31.

[0034] After completing single-sided recording, the medium M is sent to the reversal path T10, then switches back in the reversal path T10 and is transported in the reverse direction towards the -Z side. It is then transported from the reversal path T10 through the reversal path T11 to the -Z side. After being transported along the reversal path T11 by transport roller pairs 55 and 56 provided along the reversal path T11, it joins the transport path T7. In other words, the medium M that has passed through the reversal paths T10 and T11 via the switchback is re-supplied to the transport path T7 with its front and back orientation reversed. At this time, the re-supplied medium M is transported along the transport path T7 with the second side, which is the side opposite to the recorded first side, facing the liquid discharge head 30A. The liquid discharge head 30A records on the second side of the re-supplied medium M. After completing double-sided recording by recording on the second side, the medium M is discharged to the mounting section 31 from the transport path T8 or transport path T9. In this example, the transport path T includes reversal paths T10 and T11 as an example of a switchback path.

[0035] The first cover 21 is positioned in a location corresponding to the reversal paths T10 and T11. In this example, the first cover 21 forms the reversal paths T10 and T11, which are examples of switchback paths. The transport roller pair 45 provided along the transport path T7 consists of a drive roller 45A and a driven roller 45B. The transport roller pair 46 consists of a drive roller 46A and a driven roller 46B. Furthermore, the transport roller pair 54 provided along the reversal path T10 consists of a drive roller 54A and a driven roller 54B. The transport mechanism 70 that forms the reversal paths T10 and T11 is assembled on the back surface of the first cover 21. That is, when the first cover 21 is opened, the transport mechanism 70 is separated from the main body of the device 12.

[0036] As shown in Figure 2, the second cover 22 is positioned so that its Z-axis position coincides with the Z-axis position of the cassette 20. The first cover 21 is positioned so that its Z-axis position does not coincide with the Z-axis position of the cassette 20, and it covers the transport path downstream of the transport path covered by the second cover 22. The transport paths covered by the second cover 22 are the first transport path T1 and the second transport path T2. The transport paths covered by the first cover 21 are the seventh transport path T7 and the reversal paths T10 and T11, and the transport paths covered by the third cover 23 are the third transport path T3 and the fourth transport path T4.

[0037] The control unit 37 includes a CPU (Central Processing Unit), ROM (Read-only Memory), RAM (Random Access Memory), and storage, which are not shown in the diagram. The control unit 37 controls the transport of the medium M in the printer unit 15 and the recording operation on the medium M by the liquid ejection head 30A. More specifically, the control unit 37 is not limited to performing software processing for all the processes it performs. For example, the control unit 37 may have a dedicated hardware circuit (e.g., an application-specific integrated circuit: ASIC) that performs hardware processing for at least a portion of the processes it performs. That is, the control unit 37 can be configured as a circuit including one or more processors that operate according to a computer program (software), one or more dedicated hardware circuits that perform at least a portion of the various processes, or a combination thereof. The processor includes a CPU and memory such as RAM and ROM, and the memory stores program code or instructions configured to cause the CPU to execute the processing. Memory, or computer-readable storage medium, includes any available medium that can be accessed by a general-purpose or dedicated computer.

[0038] The printer unit 15 is equipped with multiple sensors (detection units), not shown, capable of detecting the presence or absence of a medium M on the transport path T. The control unit 37 determines whether the medium M is in the correct position on the transport path T when performing a recording operation to record on the medium M. If it is detected that the medium M is in an inappropriate position on the transport path T, it determines that a jam has occurred due to the medium M being stuck. Based on the detection signals from the multiple sensors, the control unit 37 identifies the location of the jam and displays a message on the display unit 19A indicating that a jam has occurred. The message includes information about the cover that should be opened to perform jam removal. The user opens the cover indicated in the message and performs the jam removal.

[0039] <Configuration of the recording device's control unit> Figure 3 is a block diagram showing the configuration of the control unit 37 shown in Figure 2. The control unit 37 mainly consists of a print engine unit 200 that manages the printer unit 15, a scanner engine unit 300 that manages the image reading unit 13, and a controller unit 100 that manages the entire multifunction device 11. The print controller 202 controls the various mechanisms of the print engine unit 200 according to the instructions of the main controller 101 of the controller unit 100. The various mechanisms of the scanner engine unit 300 are controlled by the main controller 101 of the controller unit 100. The details of the configuration of the control unit 37 will be described below.

[0040] In the controller unit 100, the main controller 101, which is composed of a CPU, controls the entire multifunction printer 11 using the RAM 106 as the work area, according to the program and various parameters stored in the ROM 107. For example, when a print job is input from the host device 400 via the host I / F 102 or wireless I / F 103, the image processing unit 108 performs predetermined image processing on the received image data according to the instructions of the main controller 101. Then, the main controller 101 transmits the processed image data to the print engine unit 200 via the print engine I / F 105.

[0041] The multifunction printer 11 may acquire image data from the host device 400 via wireless or wired communication, or it may acquire image data from an external storage device (such as a USB memory stick) connected to the multifunction printer 11. The communication method used for wireless or wired communication is not limited. For example, Wi-Fi (Wireless Fidelity) (registered trademark) and Bluetooth (registered trademark) can be used as communication methods for wireless communication. USB (Universal Serial Bus) can be used as a communication method for wired communication. Also, for example, when a read command is input from the host device 400, the main controller 101 transmits this command to the scanner engine unit 300 via the scanner engine I / F 109.

[0042] The control panel 19 is a mechanism for the user to perform input and output operations to the multifunction device 11. Through the control panel 19, the user can instruct operations such as copying and scanning, set the print mode, and access information about the multifunction device 11.

[0043] In the print engine unit 200, the print controller 202, which is composed of a CPU, controls the various mechanisms of the printer unit 15, using the RAM 204 as the work area, according to the program and various parameters stored in the ROM 203. When various commands and image data are received via the controller I / F 201, the print controller 202 temporarily stores them in the RAM 204. To make the liquid ejection head 30A available for recording, the print controller 202 instructs the image processing controller 205 to convert the stored image data into recording data. Once the recording data is generated, the print controller 202 instructs the liquid ejection head 30A to perform a recording operation based on the recording data via the head I / F 206. At this time, the print controller 202 drives each component of the transport unit 40 shown in Figure 2 via the transport control unit 207 to transport the medium M. Specifically, these components are the feed roller 41 and separation roller pair 42 for the cassette 20, and the feed roller 43 and separation roller 44 for the feed tray 24. The transport system consists of transport roller pairs 45-47, 54-56, discharge roller pairs 49, 51, 53, transport rollers 61-64, and input roller 65. Following instructions from the print controller 202, the recording operation by the liquid discharge head 30A is performed in conjunction with the transport operation of the medium M, and the printing process is carried out.

[0044] The head carriage control unit 208 changes the orientation and position of the liquid ejection head 30A according to the operating status of the multifunction printer 11, such as the maintenance status and recording status. The ink supply control unit 209 controls the ink supply unit that supplies ink to the recording unit 30 so that the pressure of the ink supplied to the liquid ejection head 30A is within an appropriate range. The ink supply unit consists of a liquid supply source 35. The maintenance control unit 210 controls the operation of the cap unit and wiping unit in the maintenance unit (not shown) when performing maintenance operations on the liquid ejection head 30A.

[0045] In the scanner engine unit 300, the main controller 101 controls the hardware resources of the scanner controller 302, using the RAM 106 as the work area, according to the program and various parameters stored in the ROM 107. This controls the various mechanisms of the image reading unit 13. For example, the main controller 101 controls the hardware resources in the scanner controller 302 via the controller I / F 301, so that the document placed on the automatic document feeding unit 14 is transported via the transport control unit 304 and read by the sensor 305. The scanner controller 302 then stores the read image data in the RAM 303. The print controller 202 converts the acquired image data as described above into recording data, so that the liquid ejection head 30A can perform a recording operation based on the image data read by the scanner controller 302.

[0046] <Cover composition> Figure 4 shows the side view 12S of the printer unit 15 where the cover CV is provided. The main body of the device 12 has a first opening 121 in the area facing the first cover 21. The first cover 21 closes the first opening 121 when closed and opens the first opening 121 when open. The main body of the device 12 has a second opening 122 in the area facing the second cover 22. The second cover 22 closes the second opening 122 when closed and opens the second opening 122 when open. The main body of the device 12 has a third opening 123 in the area facing the third cover 23. The third cover 23 closes the third opening 123 when closed and opens the third opening 123 when open.

[0047] As shown in Figure 4, the first cover 21 has a pivot shaft 21B extending along the Z axis and is rotatably mounted relative to the device body 12. The second cover 22 is located on the -Z side of the first cover 21 and has a pivot shaft 22B extending along the Y axis on the -Z side and is rotatably mounted relative to the device body 12. Since the cover CV is divided into the first cover 21 and the second cover 22, the transport path T spanning the first cover 21 and the second cover 22 can be continuously opened by opening the first cover 21 and the second cover 22. Continuous opening means, for example, that in the closed state, there are no non-door portions such as frames or exteriors that separate the first opening 121 corresponding to the first cover 21 and the second opening 122 corresponding to the second cover 22. In other words, in the open state, there are no non-door portions such as frames or exteriors that separate the first opening 121 corresponding to the first cover 21 and the second opening 122 corresponding to the second cover 22. Therefore, when both the first cover 21 and the second cover 22 are opened, the first opening 121 and the second opening 122 form one large, continuous opening.

[0048] In Figure 4, the area occupied by the second cover 22 on the side 12S is smaller than that of the first cover 21, but this size is not the only option. The area occupied by the first cover 21 and the second cover 22 on the side 12S may be the same. Also, for example, if the third cover 23 is eliminated and the second cover 22 is made large enough to cover the first to fourth transport paths T1 to T4, then the area occupied by the second cover 22 on the side 12S may be larger than that of the first cover 21.

[0049] As shown in Figure 4, the Y-axis dimension LY1 of the first cover 21 may be greater than the Z-axis dimension LZ2 of the second cover 22 (LY1 > LZ2). The Y-axis dimension LY1 of the first cover 21 may also be smaller than the Z-axis dimension LZ1 of the first cover 21 (LY1 <LZ1)。

[0050] The Y-axis dimension LY2 of the second cover 22 may be greater than the Z-axis dimension LZ2 of the second cover 22 (LY2 > LZ2). The Z-axis dimension LZ2 of the second cover 22 may be less than the Z-axis dimension LZ1 of the first cover 21 (LZ2 <LZ1) 。

[0051] The dimension LY1 of the first cover 21 in the Y-axis direction may be equal to the dimension LY2 of the second cover 22 in the Y-axis direction (LY1 = LY2). Also, the side edge 21S of the first cover 21 extending in the Z-axis direction and the side edge 22S of the second cover 22 extending in the Z-axis direction may lie on a straight line in the Z-axis direction.

[0052] The third cover 23 is disposed on the -Z side of the cover CV, and has a rotation shaft 23B extending along the Y-axis orthogonal to the Z-axis on the -Z side. The third cover 23 may be configured to be rotatable about the rotation shaft 23B relative to the apparatus main body 12. A dimension LY3 of the third cover 23 in the Y-axis direction may be larger than a dimension LZ3 of the third cover 23 in the Z-axis direction (LY3>LZ3). The dimension LY3 of the third cover 23 in the Y-axis direction may be equal to a dimension LY2 of the second cover 22 in the Y-axis direction (LY2=LY3). Further, a side edge 23S of the third cover 23 extending in the Z-axis direction and a side edge 22S of the second cover 22 extending in the Z-axis direction may be on a straight line in the Z-axis direction. Furthermore, three side edges 21S, 22S, 23S may be on a straight line in the Z-axis direction.

[0053] Further, as shown in FIG. 4, dimensions LZ2, LZ3 of the second cover 22 and the third cover 23 in the Z-axis direction may be smaller than half (1 / 2) of a dimension LZ1 of the first cover 21 in the Z-axis direction (LZ2<1 / 2×LZ1, LZ3<1 / 2×LZ1).

[0054] As shown in FIG. 4, a dimension LZ4 of the cassette 20 in the Z-axis direction is smaller than the dimensions LZ2, LZ3 of the second cover 22 and the third cover 23 in the Z-axis direction (LZ4<LZ2, LZ4<LZ3).

[0055] The feeding tray 24 has a rotation shaft 24C extending along the Y-axis, and is configured to be rotatable relative to the first cover 21. As shown in FIG. 4, a dimension LY5 of the feeding tray 24 in the Y-axis direction is smaller than the dimensions LY2, LY3 of the second cover 22 and the third cover 23 in the Y-axis direction (LY5<LY2, LY5<LY3). Further, a dimension LZ5 of the feeding tray 24 in the Z-axis direction may be larger than the dimensions LZ2, LZ3 of the second cover 22 and the third cover 23 in the Z-axis direction (LZ5>LZ2, LZ5>LZ3).

[0056] <Configuration of Recording System Having Paper Feed Unit> Figure 5 shows the configuration of the recording system 10A. As shown in Figure 4, the recording system 10A, as an example of a media transport system, comprises a multifunction printer 11 and a high-capacity paper feed unit 80 that supplies media M to the multifunction printer 11. The high-capacity paper feed unit 80 is used in conjunction with the multifunction printer 11. In this example, the high-capacity paper feed unit 80 is coupled to the multifunction printer 11 at the portion of the second cover 22. The high-capacity paper feed unit 80 is arranged in line with the main body of the device 12 in the X-axis direction. The high-capacity paper feed unit 80 accommodates multiple media M. The maximum number of media that the high-capacity paper feed unit 80 can accommodate is greater than the maximum number of media that each cassette 20 can accommodate. The high-capacity paper feed unit 80 feeds the contained media M to the transport path T of the multifunction printer 11. The main body 12 of the multifunction printer 11 is configured to be able to receive media M from the high-capacity paper feed unit 80 to the transport path T.

[0057] As shown in Figure 5, the high-capacity paper feed unit 80 comprises a housing 81, a high-capacity cassette 82 that is detachable from the housing 81, and casters 83 that make contact with the mounting surface F. The high-capacity cassette 82 has a handle 82A on the side facing the Y-axis (front) that is operated by the user when pulling it out. As shown in Figure 5, the Z-axis dimension LZ6 of the high-capacity cassette 82 is larger than the Z-axis dimension LZ4 (see Figure 4) of the cassette 20 on the multifunction printer 11 side. Therefore, the number of sheets that can be loaded into the high-capacity cassette 82 is greater than the number of sheets that can be loaded into the cassette 20. The high-capacity cassette 82 has a height dimension of approximately four times that of the cassette 20.

[0058] As shown in Figure 5, the height dimension H1 of the high-capacity paper feed unit 80 from the mounting surface F is slightly higher than the top edge height of the uppermost first cassette 20A in the multifunction printer 11 equipped with four cassettes 20. The height dimension H1 of the high-capacity paper feed unit 80 is set so as not to interfere with the feed tray 24 when the feed tray 24 of the multifunction printer 11 is opened.

[0059] As shown in Figure 6, when opening at least one of the second cover 22 and the third cover 23, the high-capacity paper feed unit 80 is moved a predetermined distance in the X-axis direction away from the multifunction printer 11. This predetermined distance is the distance required to open at least one of the second cover 22 and the third cover 23. The dimensions LZ2 and LZ3 of the second cover 22 and the third cover 23 in the Z-axis direction are smaller than their respective dimensions LY2 and LY3 in the Y-axis direction (see Figure 4). Furthermore, it is preferable that the dimensions LZ2 and LZ3 are smaller than half (1 / 2) of the Z-axis direction dimension LZ1 of the first cover 21 (LZ2 < 1 / 2 × LZ1, LZ3 < 1 / 2 × LZ1). In these cases, the distance that the high-capacity paper feed unit 80 needs to be moved in the X-axis direction when opening the second cover 22 or the third cover 23 is shorter.

[0060] <Configuration of mounting section> Figure 7 is a top view of the mounting section 31. As shown in Figure 7, the mounting section 31 has a discharge tray 32. The mounting section 31 also has a mounting surface 91 on which the media M discharged from the discharge port 71 (Figure 8) is placed. A vertical wall 99 is provided at the -X end of the mounting surface 91, extending upright from the mounting surface 91 in the +Z direction. When viewed from a position in the +X direction relative to the multifunction printer 11, the vertical wall 99 is formed in a substantially rectangular shape, with its Y dimension being longer than its Z dimension. The vertical wall 99 is also formed in a plate shape with a predetermined thickness in the X direction. The vertical wall 99 is positioned in the -Z direction relative to the discharge port 71. The width of the vertical wall 99 in the Y direction is wider than the maximum Y-direction width of the media M used in the multifunction printer 11. The height of the vertical wall 99 in the Z direction is higher than the maximum stacking height of the multiple media M placed on the mounting section 31.

[0061] As shown in Figures 7 and 8, the mounting surface 91 includes, for example, a first mounting surface 92, second mounting surfaces 94 and 95, third mounting surfaces 96 and 97, and a fourth mounting surface 98. The first mounting surface 92 constitutes the central part of the mounting surface 91 in the Y direction. Furthermore, the first mounting surface 92 is a surface that rises towards the +C direction (+Z direction) from the +B direction (+X direction). In other words, the first mounting surface 92 is a plane parallel to the BY surface. Moreover, the first mounting surface 92 is formed in a rectangular shape, with the dimension in the B direction being longer than the dimension in the Y direction when viewed from the C direction. A through hole 93 is formed in the central part of the first mounting surface 92 in the Y direction, as an example of an opening. The through hole 93 is formed in a rectangular shape, with the dimension in the B direction being longer than the dimension in the Y direction, as an example. The size of the through hole 93 is such that the movable rib 90, which will be described later, can pass through. As a result, the movable rib 90 can move in the C direction through the through hole 93 and protrude from the first mounting surface 92. In this specification, the elements involved in the discharge of the medium M, specifically the print controller 202, the discharge roller pairs 49, 51, 53, and the discharge port 71, are collectively referred to as the discharge section. The B direction has the discharge direction component when the medium M is discharged from the discharge port 71. The Y direction is perpendicular to the B direction and the discharge direction. Here, a configuration in which these directions are perpendicular is shown, but they do not necessarily have to be perpendicular; a configuration in which they are approximately perpendicular (i.e., a crossing state shifted by a few degrees from 90 degrees) is also acceptable.

[0062] The second mounting surfaces 94 and 95 are located on one side of the first mounting surface 92 in the Y direction. The second mounting surface 94 is continuous with the first mounting surface 92 and is located in the +Y direction more than the first mounting surface 92. The length of the second mounting surface 94 in the B direction decreases as it approaches the +Y direction. Also, the second mounting surface 94 slopes downward in the -C direction as it approaches the -Y direction. In other words, the second mounting surface 94 slopes toward the first mounting surface 92. The second mounting surface 95 is continuous with the first mounting surface 92 and is located in the -Y direction more than the first mounting surface 92. The length of the second mounting surface 95 in the B direction decreases as it approaches the -Y direction. Also, the second mounting surface 95 slopes downward in the -C direction as it approaches the +Y direction. In other words, the second mounting surface 95 slopes toward the first mounting surface 92. The inclination angle of the second mounting surface 94 with respect to the BY surface and the inclination angle of the second mounting surface 95 are approximately the same. The area and inclination angle of the second mounting surfaces 94 and 95 are set so that the second mounting surfaces 94 and 95 can come into contact with the medium M.

[0063] The third mounting surfaces 96 and 97 are located outside the first mounting surface 92 and the second mounting surfaces 94 and 95 in the Y direction. The third mounting surface 96 is continuous with the second mounting surface 94 and is located further in the +Y direction than the second mounting surface 94. The third mounting surface 96 is formed in a nearly rectangular shape, except for a cutout in the -B direction. Also, the third mounting surface 96 is parallel to the Y direction. In other words, the third mounting surface 96 is a plane parallel to the BY plane, similar to the first mounting surface 92. The third mounting surface 97 is continuous with the second mounting surface 95 and is located further in the -Y direction than the second mounting surface 95. The third mounting surface 97 is formed in a nearly rectangular shape, except for a cutout in the -B direction. Also, the third mounting surface 97 is parallel to the Y direction. In other words, the third mounting surface 97 is a plane parallel to the BY plane, similar to the first mounting surface 92.

[0064] The fourth mounting surface 98 is a surface located in the +B direction, continuous with the first mounting surface 92, the second mounting surfaces 94 and 95, and the third mounting surfaces 96 and 97. Furthermore, the fourth mounting surface 98 is, for example, a plane parallel to the horizontal XY plane. At the -B direction end of the fourth mounting surface 98, the central part in the Y direction is recessed in the +B direction compared to both ends in the Y direction.

[0065] As shown in Figure 9, the movable rib 90 is an example of a projection that can project from the mounting surface 91 in the C direction, and is formed in the shape of a hollow rectangular parallelepiped that is long in the B direction. The end of the movable rib 90 in the -C direction is open. The movable rib 90 also has a side wall 72 formed in the shape of a frame when viewed from the C direction, an upper wall 74 that covers the end of the side wall 72 in the +C direction, and two slide rails 76 provided on the inside of the side wall 72. A notch 73 is formed at the end of the side wall 72 in the +B direction. The upper surface 74A of the upper wall 74 in the +C direction is a plane parallel to the BY plane. The upper surface 74A is also formed in the shape of a rectangle where the dimension in the B direction is longer than the dimension in the Y direction when viewed from the C direction.

[0066] The movable rib 90, which extends in the B direction, has a dimension in the B direction that is greater than its dimension in the Y direction. Furthermore, the movable rib 90 has a dimension in the B direction that is smaller than the B direction dimension of the largest size medium M used in the multifunction printer 11. Additionally, the movable rib 90 has a dimension in the Y direction that is smaller than the Y direction dimension of the smallest size medium M used in the multifunction printer 11. The movable rib 90 is moved back and forth in the C direction by a moving part 77 (described later), allowing it to move between a protruding position that extends from the mounting surface 91 in the +C direction and a retracted position where the mounting surface 91 and the upper surface 74A are at approximately the same height in the C direction. The protruding position is an example of a second position. The retracted position is an example of a first position. The movable rib 90 also supports a portion of the medium M in both the protruding and retracted positions. In this disclosure, the medium M is transported using a center-resist method. Therefore, the movable rib 90 supports approximately the center of the medium M in the Y direction.

[0067] The movable section 77 is configured, for example, as a link mechanism. Specifically, the movable section 77 includes a support plate 78, a movable rod 79, two first link members 84 spaced apart in the B direction, and one second link member 85 connected to each of the two first link members 84. The support plate 78 extends in the B direction in the -C direction relative to the movable rib 90. The movable rod 79 is provided between the support plate 78 and the movable rib 90 so as to be able to reciprocate in the B direction. The movable rod 79 is also moved back and forth in the B direction by a motor (not shown). This motor is controlled by a transport control unit 207 (Figure 3). The position of the movable rod 79 in the B direction is detected by a sensor (not shown). Based on this detection result, it is determined whether the movable rib 90 is in the protruding position or the retracted position. The position information of the movable rib 90 is sent to the control unit 37.

[0068] The first link member 84 is a member that is long in one direction. One end of the first link member 84 is connected to the support plate 78 so as to be rotatable around an axis along the Y direction. The other end of the first link member 84 is connected to the slide rail 76 so as to be rotatable around an axis along the Y direction and to move together with the slide rail 76. The second link member 85 is a member that is long in one direction and is shorter than the first link member 84. One end of the second link member 85 is connected to a part of the first link member 84 so as to be rotatable around an axis along the Y direction. The other end of the second link member 85 is connected to the moving rod 79 so as to be rotatable around an axis along the Y direction.

[0069] In the moving section 77, when the moving rod 79 is moved in the +B direction, one end of the second link member 85 moves downward in the -C direction, causing the other end of the first link member 84 to move downward in the -C direction and slide relative to the slide rail 76 in the +B direction. This causes the moving section 77 to lower the movable rib 90 in the -C direction. Also, in the moving section 77, when the moving rod 79 is moved in the -B direction, one end of the second link member 85 moves upward in the +C direction, causing the other end of the first link member 84 to move upward in the +C direction and slide relative to the slide rail 76 in the -B direction. This causes the moving section 77 to move the movable rib 90 in the +C direction. In other words, the moving section 77 causes the movable rib 90 to protrude from the mounting surface 91 in the +C direction.

[0070] <Configuration of a recording system with a post-processing device> Figure 10 shows a recording system 10B including a multifunction printer 11. As shown in Figure 10, the recording system 10B comprises a multifunction printer 11 and a post-processing device 86. The multifunction printer 11 is equipped with a liquid ejection head 30A that performs recording by ejecting ink, which is an example of a liquid, onto a medium M, such as paper. Here, the liquid ejection head 30A is described as a line head, but it is not particularly limited to that.

[0071] The multifunction printer 11 comprises a main unit 12, a cassette 20 for containing media, a transport unit 40 (see Figure 2) for transporting media, a liquid discharge head 30A, a mounting unit 31 for discharging media, and a relay unit 88 for transporting media to a post-processing device 86. As shown in Figure 10, a media transport path TA is provided inside the main unit 12, specifically directly below the liquid discharge head 30A.

[0072] The liquid ejection head 30A has multiple nozzles (not shown) arranged to cover the entire Y-axis area of ​​the medium. The liquid ejection head 30A records data onto the medium by ejecting ink supplied from an ink tank (not shown) from the multiple nozzles toward the medium.

[0073] The media recorded on by the multifunction printer 11 is sent to the post-processing device 86 via the relay unit 88. The post-processing device 86 comprises a main unit 89, a processing tray 58 and a stapler 57 (an example of a post-processing unit) located inside the main unit 89, and a main tray 59 located outside the main unit 89. The media received from the relay unit 88 to the main unit 89 is transported along the transport path TB inside the main unit 89 and sent to the processing tray 58.

[0074] <Configuration of the relay unit> Figure 11 shows the area around the mounting section 31 when the post-processing device 86 is connected to the multifunction printer 11.

[0075] As shown in Figure 11, the relay unit 88 has a relay transport section capable of transporting the medium M discharged from the discharge port 71 to the post-processing device 86. The relay unit 88 also includes, as an example, a main frame (not shown), an upper path member 111, a rotating mechanism 130, a lower path member 116, a first rotating shaft 117, a second rotating shaft 118, and a spring member (not shown). The relay path TC is defined as the path between the discharge roller pair 120 of the discharge port 71 and the post-processing device 86 within the transport path T of the medium M. In other words, the transport path T in this example includes the relay path TC.

[0076] As shown in Figure 11, the upper path member 111 constitutes the upper part of the relay path TC located in the +Z direction from the center in the Z direction. The upper path member 111 is provided with a rotating mechanism 130, which will be described later. The upper path member 111, as an example, has an inclined wall 112 and an upper wall 113. The inclined wall 112 is located downstream in the E direction of the discharge guide 119. The E direction is the direction in which the medium M is transported in the relay path TC within the relay unit 88. The inclined wall 112 is inclined such that its +X direction end is located in the +Z direction relative to its -X direction end. In other words, the inclined wall 112 extends diagonally upward relative to the discharge guide 119. The upper wall 113 extends in the +X direction, starting from the point where the inclined wall 112 and the upper wall 113 connect at the +X direction end of the inclined wall 112. This connecting point is curved.

[0077] The rotating mechanism 130 is driven by a drive motor (not shown) to transport the medium M from the discharge port 71 to the post-processing device 86. The rotating mechanism 130 is composed of, for example, a plurality of upper rollers 131, a drive motor (not shown), a plurality of spurs (also called serrated rollers) 132, and a gear section (not shown). The plurality of upper rollers 131 are arranged at intervals in the E direction on the upper path member 111. In addition, a plurality of upper rollers 131 are also arranged in the Y direction. The plurality of upper rollers 131 rotate around a rotation axis along the Y direction. A portion of the outer circumferential surface of the plurality of upper rollers 131 is exposed from the upper path member 111 to the relay path TC and can come into contact with the medium M.

[0078] Multiple spurs 132 are provided on the upper path member 111 at intervals in the E direction and at positions different from the multiple upper rollers 131, and multiple spurs 132 are also arranged in the Y direction. Each of the multiple spurs 132 rotates around a rotation axis along the Y direction. Multiple teeth (not shown) are provided on the outer circumference of the multiple spurs 132. The outer diameter of the spurs 132 is smaller than the outer diameter of the upper rollers 131. The multiple spurs 132 rotate by contact with the conveyed medium M.

[0079] As shown in Figure 11, the lower path member 116 constitutes the lower part of the relay path TC located in the -Z direction from the center in the Z direction. The lower path member 116 is an example of a switching member. The lower path member 116 is configured to switch between a first state in which it constitutes the relay path TC for the medium M from the discharge port 71 to the post-treatment device 86, and a second state in which it opens the relay path TC toward the mounting section 31. Note that the lower path member 116 is not provided with a drive motor or gear section as a rotating mechanism section 130.

[0080] The lower path member 116 includes, for example, a first lower path member 133 and a second lower path member 134. The width of the first lower path member 133 and the second lower path member 134 in the Y direction is wider than the width of the medium M in the Y direction. The first lower path member 133 is rotatable about a first rotation axis 117. The second lower path member 134 is rotatable about a second rotation axis 118. Here, the first state and the second state are switched by the rotation of the first lower path member 133 of the lower path member 116 about the first rotation axis 117. In this embodiment, for example, the first and second states are not defined for the rotation of the second lower path member 134.

[0081] As shown in Figure 11, the first rotation axis 117 is located in the -X and -Z directions relative to the middle of the relay path TC in the E direction (specifically, the center of the relay path TC). The first rotation axis 117 is rotatably supported by a frame member (not shown) of the device body 12. The first rotation axis 117 extends in the Y direction, intersecting both the E and Z directions. The first rotation axis 117 consists of a cylindrical member. The first rotation axis 117 rotatably supports the first lower path member 133. Specifically, the base end 133A of the first lower path member 133 is attached to the first rotation axis 117. The first state and the second state are switched by the first lower path member 133 rotating around the first rotation axis 117.

[0082] The second lower path member 134 is located downstream in the E direction relative to the first lower path member 133. The second rotation axis 118 is located in the -Z direction relative to the upper wall 113. The second rotation axis 118 is rotatably supported by a frame member (not shown) of the device body 12. The second rotation axis 118 consists of a cylindrical member extending in the Y direction. The second rotation axis 118 rotatably supports the second lower path member 134. Specifically, the base end 134A in the +X direction of the second lower path member 134 is attached to the second rotation axis 118. In other words, the downstream end in the E direction of the second lower path member 134 is rotatably supported by the second rotation axis 118. The second lower path member 134 then switches between a closed state that forms the relay path TC and an open state that opens the relay path TC by rotating around the second rotation axis 118.

[0083] In the first state of the lower path member 116, the first lower path member 133 faces the inclined wall 112, forming the upstream portion of the relay path TC. The arrangement in which the first lower path member 133 faces the inclined wall 112 is defined as the first state of the first lower path member 133. In the first state of the lower path member 116, the second lower path member 134 faces the upper wall 113, forming the downstream portion of the relay path TC.

[0084] <First modified example of the relay unit> Figure 12 shows the area around the mounting section 31 when the post-processing device 86 is connected to the multifunction device 11, as a first modification of Figure 11. This modification differs from Figure 11 in that it has a linear upper path member 152 and a plate-shaped lower path member 154 instead of the upper path member 111 and lower path member 116. In this modification, the first rotation axis 117 (Figure 11) is not provided. The upper path member 152 is inclined such that its end in the +X direction is located in the +Z direction relative to its end in the -X direction.

[0085] In the first state, when the lower path member 154 forms a relay path TC together with the upper path member 152, the lower path member 154 has a predetermined thickness in the C direction and extends in the B direction. The base end 154A of the lower path member 154 in the +B direction is rotated around the second rotation axis 118. The lower path member 154 switches between the aforementioned first state and a second state, where it is retracted from the relay path TC in the -Z direction. In this modified example, when the lower path member 154 is in the second state, the medium M is discharged into the space on the mounting surface 91. Thus, the lower path member 154 may be composed of a single member. Alternatively, instead of providing the second rotation axis 118, a first rotation axis 117 (Figure 11) may be provided, and the base end of the lower path member 154 in the -B direction may be rotated around the first rotation axis 117. Alternatively, instead of providing the first rotating shaft 117 and the second rotating shaft 118, a lifting mechanism 166 (Figure 14) may be provided to raise and lower the lower path member 154.

[0086] <Second variation of the relay unit> Figure 13 shows the area around the mounting section 31 when the post-processing device 86 is connected to the multifunction printer 11, as a modified example of Figure 11. This modified example differs from Figure 11 in that an upper path member 142 is provided as an example of an upper path member instead of the upper path member 111 (Figure 11), and a first lower path member 146 is provided as an example of a lower path member instead of the first lower path member 133 (Figure 11). The other configurations are the same as in Figure 11.

[0087] The upper path member 142 constitutes the upper part of the relay path TC, located in the +Z direction from the center in the Z direction. The upper path member 142 is provided with a rotating mechanism 130. The upper path member 142, as an example, has an inclined wall 112 and an upper wall 113. The inclined wall 112 is located downstream in the E direction from the discharge guide 119. The inclined wall 112 is inclined such that its end in the +X direction is located in the +Z direction relative to its end in the -X direction. In other words, the inclined wall 112 is a wall that extends diagonally upward from the discharge guide 119.

[0088] The first lower path member 146 is formed in the shape of a plate having a predetermined thickness. The first lower path member 146 is formed in the shape of a rectangle in which the dimension in the Y direction is longer than the dimension in the E direction. The upstream end of the first lower path member 146 in the E direction is defined as the base end 146A. The downstream end of the first lower path member 146 in the E direction is defined as the tip end 146B. In other words, the tip end 146B is located opposite to the base end 146A. The base end 146A is rotatably mounted on the first rotation axis 117. When the first lower path member 146 is rotated around the first rotation axis 117, the trajectory traced by the tip end 146B is defined as the rotation trajectory R. The region inside the rotation trajectory R is defined as the rotation region SR. The mounting surface 91 is located outside the rotation trajectory R of the tip end 146B. In other words, when the first lower path member 146 is rotated, the first lower path member 146 does not come into contact with the mounting surface 91.

[0089] <Third variation of the relay unit> Figure 14 shows the area around the mounting section 31 when the post-processing device 86 is connected to the multifunction device 11, as a modified example of Figure 13. This modified example differs from Figure 13 in that the first rotating shaft 117 and the second rotating shaft 118 (Figure 13) are absent, a first lower path member 163 is provided in place of the first lower path member 146, and a lifting section 166 is provided. The other configurations are the same as in Figure 13.

[0090] The lower path member 162 includes, for example, a first lower path member 163 and a second lower path member 164 located downstream of the first lower path member 163 in the E direction. The first lower path member 163 is provided so as to be retractable from the relay path TC in the -Z direction. The lower path member 162 switches from a first state to a second state when the first lower path member 163 is retracted from the relay path TC.

[0091] Specifically, the first lower path member 163 is formed in a plate shape having a predetermined thickness in the C direction and extending in the B direction. The first lower path member 163 switches between a first state and a second state when the lifting unit 166 is driven. In the first state, the first lower path member 163 faces the inclined wall 112 and forms a relay path TC. In the second state, the first lower path member 163 is retracted from the relay path TC in the -Z direction and rests on the mounting surface 91.

[0092] The second lower path member 164 is formed in a plate shape having a predetermined thickness in the Z direction. For example, the second lower path member 164 is fixed in a state where it faces the upper wall 113 and forms a relay path TC.

[0093] [First Embodiment] <Recording System Configuration> The configuration of the recording system in this embodiment will be described below with reference to Figure 15. Figure 15 is a diagram showing the overall configuration of the recording system when the post-processing device is attached to the multifunction printer.

[0094] As shown in Figure 15, the recording system 10B comprises a paper supply unit (not shown, for example, the high-capacity paper feed unit 80 in Figure 5), a multifunction printer 11, an image reading unit 13, a relay unit 88, and a post-processing device 86. The recording system 10B is configured as an inkjet recording system that performs recording by ejecting ink, an example of a liquid, onto paper, an example of a medium.

[0095] The multifunction device 11 is positioned in the +X direction (see Figure 5) relative to the supply unit. The multifunction device 11 consists of a cassette 20, a transport unit 40, a liquid discharge head 30A, a first discharge path T01 and a second discharge path T02, a mounting unit 31, an image reading unit 13, a relay unit 88, and an operation panel 19.

[0096] Cassette 20 holds multiple sheets of paper. Transport unit 40 transports the paper fed from cassette 20. Liquid ejection head 30A functions as a recording unit that ejects liquid such as ink from nozzles to record an image on the paper.

[0097] The first discharge path T01 and the second discharge path T02 are paper transport paths, respectively, that guide the paper recorded by the liquid ejection head 30A to the outside of the main unit 12. Specifically, the first discharge path T01 is configured as part of the discharge unit 60 that discharges paper, and is a path that transports paper from the liquid ejection head 30A to the mounting unit 31. On the other hand, the second discharge path T02 is configured as part of the discharge unit 60 that discharges paper, and is a path that transports paper from the liquid ejection head 30A to the relay unit 88. Paper discharged via the first discharge path T01 is placed on the mounting unit 31. The relay unit 88 relays and transports paper between the multifunction printer 11 and the post-processing device 86.

[0098] The image reading unit 13 is attached to the +Z end of the multifunction printer 11 and reads information from a document (not shown).

[0099] The relay unit 88 includes a transport path and transport means for transporting paper ejected from the multifunction printer 11 to the post-processing device 86. The relay unit 88 is located at the +Z end of the device body 12 of the multifunction printer 11 and in the -Z direction relative to the image reading unit 13. The relay unit 88 and the relay transport unit 66 are provided adjacent to the mounting unit 31, and in the example shown in Figure 15, they are provided above the mounting unit 31.

[0100] The post-processing device 86 is an example of a post-processing unit that performs post-processing on paper transported via the second discharge path T02 and the relay unit 88. The post-processing device 86 is positioned in the +X direction relative to the multifunction printer 11. Specifically, the post-processing device 86 is positioned downstream of the second discharge path T02 and the relay unit 88 in the paper transport direction. The post-processing device 86 has a transport path TB as a path through which paper fed from the relay unit 88 is transported. A stapler 57, a processing tray 58, and a main tray 59 are provided downstream of the transport path TB.

[0101] As an example of post-processing, the stapler 57 performs stapling to bind a predetermined number of sheets of paper. The stack of stapled paper is discharged into the processing tray 58. Post-processing of paper includes punching holes in the paper, folding the stack of paper, cutting the paper, folding the paper into signatures, and binding the paper into a book.

[0102] The control panel 19 functions as a notification means to inform the user of errors such as paper jams.

[0103] <Configuration of the relay unit> The configuration of the relay unit in this embodiment will be described below with reference to Figure 16. Figure 16 is a diagram showing the configuration of the relay unit 88 in this embodiment. As shown in the figure, the relay unit 88 is a unit for sending the media sent from the multifunction printer 11 to the post-processing device 86, and is located above the mounting section 31. This relay unit 88 may be implemented as part of the multifunction printer 11, or it may be implemented as a separate device from the multifunction printer 11 that is attached to the multifunction printer 11.

[0104] The relay unit 88 has a relay transport section 66. The relay transport section 66 has a transport guide 67, a detection means 68, a biasing means 69, and a pivot shaft 75.

[0105] The upper path member 111 constitutes the upper part of the relay path TC, which is the paper transport path, located in the +Z direction from the center in the Z direction.

[0106] The transport guide 67 acts as a lower path member of the relay path TC and rotates around the pivot axis 75. The transport guide 67 switches between a first state, which is a closed state in which it forms the relay path TC together with the upper path member 111, and a second state, which is an open state in which it rotates around the pivot axis 75 to open the relay path TC. In the second state, the transport guide 67 enters the area where the media is placed in the placement section 31, so if there is paper remaining in the placement section 31, it may damage the remaining paper. Also, when the transport guide 67 is in the second state, the user can access the paper in the open relay path TC. Therefore, if paper jams in the relay path TC, the user can remove the paper from the open relay path TC by changing the transport guide 67 from the first state to the second state. In Figure 16, the transport guide 67 in the first state is shown by a solid line, and the transport guide 67 in the second state is shown by a dashed line.

[0107] The detection means 68 is provided in the transport path T and detects the presence or absence of paper in the transport path T. In Figure 16, an example is shown in which one detection means 68 is provided in the relay path TC, which is a transport path within the relay unit, but multiple detection means may be provided, and one or more detection means may be provided at any position in the transport path of the recording device or post-processing device.

[0108] The biasing means 69 is a means for biasing the transport guide 67 to the first state (closed state).

[0109] In this embodiment, a magnet is provided on the transport guide 67 and the multifunction device 11 as a biasing means 69, and the transport guide 67 is biased to the first state (closed state) by the magnetic force of the magnet.

[0110] <First modified example of the relay unit> Figure 16 shows an example where the transport guide 67 is provided below the relay path TC in the relay transport section 66, but the position of the transport guide is not limited to below the relay path. The transport guide may be provided at any position relative to the relay path.

[0111] Figure 17 shows a first modified example of the relay unit 88 in this embodiment, in which the transport guide 67 is provided above the relay path TC.

[0112] In this example, the transport guide 67 acts as an upper path member of the relay path TC, and the lower surface of the transport guide 67 forms a relay path TC that is continuous with the second discharge path T02 of the multifunction printer 11. The upper surface of the transport guide 67 also functions as a mounting section 31 on which the medium M (paper) is placed. The transport guide 67 switches between a first state, which is a closed state in which it forms a relay path TC together with the lower path member 116, and a second state, which is an open state in which it rotates around the pivot axis 75 to open the relay path TC.

[0113] <Second variation of the relay unit> Figures 16 and 17 show an example in which the transport guide 67 rotates clockwise (or counterclockwise) on the XZ plane around an axis located downstream in the transport direction (X direction). However, the position of the axis for rotating the transport guide is not limited to this and can be set at any position. Specifically, it may be set on the rear side of the device body 12, on the upstream side in the transport direction, etc.

[0114] Figure 18 shows a second modified example of the relay unit 88 in this embodiment, in which a pivot shaft 75 is provided on the rear side of the device body 12, and the transport guide 67 rotates counterclockwise around this pivot shaft 75 in the figure, switching from the first state (closed state) to the second state (open state). In Figure 18, the transport guide 67 in the first state is shown by a solid line, and the transport guide 67 in the second state is shown by a dashed line.

[0115] In this example, if the transport guide 67 switches from the first state to the second state to clear a paper jam in the relay unit while the ejected paper remains in the loading section 31, the transport guide 67 may come into contact with the paper placed in the loading section 31, potentially causing creases or scratches on the paper.

[0116] <Third variation of the relay unit> Figures 16 to 18 show an example in which the transport guide 67 moves in the Z direction by rotating around the pivot axis 75, switching from the first state to the second state (or from the second state to the first state). However, the means of moving the transport guide is not limited to those including the pivot axis as described above, and any means of moving the transport guide may be provided.

[0117] Figure 19 shows a third modification of the relay unit 88 in this embodiment, in which the relay unit 88 has a sliding mechanism (not shown) instead of a rotating mechanism, and the transport guide 67 slides downward (or upward) by this sliding mechanism. A specific sliding mechanism could be a lifting mechanism such as the lifting section 166 (see Figure 14). In Figure 19, the transport guide 67 in the first state (closed state) is shown by a solid line, and the transport guide 67 in the second state (open state) is shown by a dashed line.

[0118] In this example, when the transport guide 67 switches from the first state to the second state to clear a paper jam in the relay unit while the ejected paper remains in the loading section 31, the transport guide 67 may come into contact with the paper placed in the loading section 31, potentially causing creases or scratches on the paper.

[0119] <Fourth modified example of the relay unit> Figures 16 to 19 show an example where a magnet is used as the biasing means, but the biasing means is not limited to a magnet, and any means may be used.

[0120] Figure 20 shows a fourth modified example of the relay unit 88 in this embodiment, in which a spring 69a is used instead of a magnet as a biasing means for biasing the transport guide 67.

[0121] In this example, a spring 69a is attached to the transport guide 67, and a pin-shaped component 69b, which is biased by the spring 69a, is attached to the side of the transport guide 67.

[0122] The groove shape 69c is provided such that when the transport guide 67 is in the first state (closed state) and in the position to form the relay path TC, it is in a position opposite to the pin-shaped component 69b. When the transport guide 67 is in the first state, the pin-shaped component 69b fits into the groove shape 69c. The groove shape 69c may be provided on the main body 12 side of the multifunction device 11, or on the relay unit 88 side.

[0123] Further, in a normal state, the opening and closing of the conveyance guide 67 is locked by a driving member such as a solenoid, and when a paper jam occurs (a jam occurs), the lock may be released in response to an operation performed by a user via a GUI screen during the paper jam error clearing process. As the solenoid, a normally closed solenoid can be used, which locks the opening and closing of the conveyance guide in a non-energized state, and is unlocked when energized to allow the opening and closing of the conveyance guide. Note that GUI is an abbreviation for graphical user interface.

[0124] <Transition of GUI Screen> Hereinafter, transition of the GUI screen in the present embodiment will be described with reference to FIGS. 21 to 23. FIG. 21 shows an example of transition of the GUI screen in the present embodiment. Specifically, FIG. 21(a) shows an example of transition in three steps, and FIG. 21(b) shows an example of transition in two steps. FIG. 22 shows another example of transition of the GUI screen. Specifically, FIG. 22(a) shows an example of transition in three steps, and FIG. 22(b) shows an example of transition in two steps.

[0125] In the present embodiment, the notification that "a paper jam has occurred" and the notification that "prompts removal of paper" are provided by screen display on a GUI screen displayed on the display unit 19A of the operation panel 19. For example, as shown in FIG. 21(a), when a paper jam is detected inside the relay unit 88 (specifically, in the relay path TC of the relay conveyance unit 66), first a notification screen 2101 notifying that "a paper jam has occurred inside the relay unit" is displayed. Further, a notification screen 2102 prompting "to remove the paper remaining on the placement unit" is displayed before a notification screen 2103 prompting "to remove the jammed paper inside the relay unit".

[0126] For example, as shown in Figure 21(b), when a paper jam is detected inside the relay unit 88 (specifically, inside the relay path TC of the relay transport unit 66), the notification screen 2105 is displayed. The notification screen 2105 is a screen that simultaneously notifies the user to "remove the paper remaining in the loading unit" and to "remove the jammed paper inside the relay unit." The screen transitions shown in Figure 21 or Figure 22 prevent the user from operating the transport guide 67, which is an opening and closing member, while paper remains in the loading unit 31, thereby preventing the user's hand or the transport guide 67 from colliding with the paper and causing damage such as scratches or folds.

[0127] In this embodiment, when the GUI screen switches, for example, when the "OK button" shown in Figures 21(a) and 21(b) is pressed, the next notification screen after the currently displayed notification screen is displayed. The user checks the contents of each GUI screen and, if necessary, presses the "OK button" when the processing of the displayed contents is completed.

[0128] Alternatively, for example, pressing a right-pointing triangle button (or left-pointing triangle button) as shown in Figures 22(a) and 22(b) may display the next notification screen (or the previous notification screen) after the currently displayed notification screen. In the figures, a black fill indicates that the button is enabled, and a white outline indicates that the button is disabled. Alternatively, the GUI screen may transition by the user sliding (swiping) the screen (not shown). Alternatively, a notification screen for the next process may be displayed after a predetermined time has elapsed (not shown). In the form where the notification screen transitions after a predetermined time has elapsed, for example, a bar may be displayed on the notification screen, and the scale inside the bar may increase as time passes, allowing the user to recognize in advance that they will move to the next notification screen and the timing of that move.

[0129] Figure 23 shows an example of GUI screen transitions in this embodiment. As shown, a message prompting the user to perform some action may be displayed along with an image (schematic diagram) explaining what specific action should be performed.

[0130] Furthermore, while the examples in Figures 21 to 23 show a configuration in which the GUI screen transitions when the user presses a button included in the GUI screen displayed on the touch panel display unit 19A, this embodiment is not limited to this configuration. For example, the multifunction printer 11 may have physical buttons for inputting "up, down, left, right," "confirm," "cancel," etc., and the screen transition described above may occur when the user presses one of these physical buttons.

[0131] Furthermore, while the examples in Figures 21 to 23 show a configuration in which user notifications are provided by displaying a GUI screen on the display unit 19A, this embodiment is not limited to this configuration. For example, user notifications may be provided by sound emitted from a speaker (not shown) attached to the multifunction device 11. Also, user notifications may be provided by appropriately combining known methods. For example, by using a notification screen like the examples in Figures 21 to 23 in combination with the illumination of an error indicator lamp, some GUI screens may be omitted.

[0132] <Modified view of the mounting section> Hereinafter, modified examples of the mounting section 31 in this embodiment will be described with reference to Figures 24 and 25.

[0133] Figure 24 shows a first modified example of the mounting section 31. As shown in the figure, the relay unit 88 in this example has the same configuration as the previously described form, but differs from the previously described form in that a mounting medium detection means 87a is provided in the mounting section 31 of the multifunction printer 11 (see Figure 16). The mounting medium detection means 87a can detect whether or not there is paper placed on the mounting section 31. In this example, the mounting medium detection means 87a is provided on the bottom surface of the mounting section 31. As the mounting medium detection means 87a, for example, a mechanism for detecting weight can be adopted, and a form can be used that detects when the paper has been removed by a change in the output of that mechanism.

[0134] Figure 25 shows a second modified example of the mounting section 31. As shown in the figure, the relay unit 88 in this example has substantially the same configuration as that in Figure 24, but differs from Figure 24 in that a mounting medium detection means 87b is provided in the mounting section 31 of the multifunction printer 11 instead of a mounting medium detection means 87a. The mounting medium detection means 87b can detect the presence or absence of paper to be placed on the mounting section 31. In this example, the mounting medium detection means 87b is positioned above the paper to be placed on the mounting section 31. The mounting medium detection means 87b is composed of a lever-shaped component and can detect the presence or absence of paper based on the amount of rotation of the lever.

[0135] In this embodiment, when a paper jam is detected in the relay path TC within the relay transport section 66 of the relay unit 88, the presence or absence of paper in the loading section 31 is detected by the loading medium detection means 87a or 87b. If, as a result of this detection, paper is found in the loading section 31, a notification prompting the user to "remove the paper remaining in the loading section" is issued before a notification prompting the user to "remove the jammed paper inside the relay unit," as shown in Figure 21(a), etc. On the other hand, if there is no paper in the loading section 31, a notification prompting the user to "remove the jammed paper inside the relay unit" is issued without issuing the notification prompting the user to "remove the paper remaining in the loading section." In other words, in this embodiment, if there is no paper in the loading section 31, the notification prompting the user to "remove the paper remaining in the loading section" is unnecessary and is therefore skipped. This makes it possible to reduce inconvenience for the user.

[0136] The means for detecting the placed media is not limited to the examples described above. For example, an optical sensor may be provided on the vertical wall 99. In this case, the presence or absence of paper in the placement section 31 can be detected based on the output of the optical sensor. Furthermore, as will be described in detail later, by adjusting the position of the optical sensor, it is possible to determine whether there is a predetermined amount of paper in the placement section 31, rather than whether there is any paper at all. In this case, it is preferable to set the position of the optical sensor to a paper height that does not affect the user's operation of the relay unit.

[0137] <Notification Sequence> The notification sequence in this embodiment will be described below with reference to Figure 26.

[0138] Figure 26(a) is a flowchart of the notification sequence when there is no detection means in the mounting section. This notification sequence is initiated when a paper jam occurs in the transport path T.

[0139] In step S2602, the CPU of the print controller 202 determines whether there is paper in the relay path TC based on the detection result of the detection means 68. If the result of this step is YES, the process proceeds to S2604. On the other hand, if the result of this step is NO, the process proceeds to S2610. Hereafter, "~step S" will be abbreviated as "~S".

[0140] In S2604, the CPU of the print controller 202 issues a notification prompting the user to remove any remaining paper from the paper holder 31. Examples of GUI screens presented to the user in this step include the notification screen 2102 in Figure 21, the notification screen 2202 in Figure 22, and the notification screen 2302 in Figure 23.

[0141] In S2606, the CPU of the print controller 202 issues a notification prompting the user to resolve a paper jam in the relay path TC. Examples of GUI screens presented to the user in this step include the notification screen 2103 in Figure 21, the notification screen 2203 in Figure 22, and the notification screen 2303 in Figure 23. As mentioned earlier, the transition from S2604 to S2606 is performed by the passage of time or by user operation.

[0142] In S2608, the CPU of the print controller 202 determines whether there is paper in the relay path TC based on the detection result of the detection means 68. If the result of this step is YES, the process returns to S2604. On the other hand, if the result of this step is NO, the process proceeds to S2610.

[0143] In S2610, the CPU of the print controller 202 hides the notification screen displayed in the preceding processing and puts the multifunction device 11 into a print-ready state.

[0144] Figure 26(b) is a flowchart of the notification sequence when there is a detection means in the mounting section. This notification sequence is initiated when a paper jam occurs in the transport path T.

[0145] In S2622, the CPU of the print controller 202 determines whether there is paper in the relay path TC based on the detection result of the detection means 68. If the result of this step is YES, the process proceeds to S2624. On the other hand, if the result of this step is NO, the process proceeds to S2634.

[0146] In S2624, the CPU of the print controller 202 determines whether there is paper in the mounting section 31 based on the detection result of the mounting medium detection means 87 (see Figures 24 and 25). If the result of this step is YES, the process proceeds to S2626. On the other hand, if the result of this step is NO, the process proceeds to S2630.

[0147] In S2626, the CPU of the print controller 202 issues a notification prompting the user to remove any remaining paper from the paper holder 31. Examples of GUI screens presented to the user in this step include the notification screen 2102 in Figure 21, the notification screen 2202 in Figure 22, and the notification screen 2302 in Figure 23.

[0148] In S2628, the CPU of the print controller 202 determines whether there is paper in the mounting section 31 based on the detection result of the mounting medium detection means 87 (see Figures 24 and 25). If the result of this step is YES, the process returns to S2626. On the other hand, if the result of this step is NO, the process proceeds to S2630.

[0149] In S2630, the CPU of the print controller 202 issues a notification prompting the user to resolve a paper jam in the relay path TC. Examples of GUI screens presented to the user in this step include the notification screen 2103 in Figure 21, the notification screen 2203 in Figure 22, and the notification screen 2303 in Figure 23.

[0150] In S2632, the CPU of the print controller 202 determines whether there is paper in the relay path TC based on the detection result of the detection means 68. If the result of this step is YES, the process returns to S2630. On the other hand, if the result of this step is NO, the process proceeds to S2634.

[0151] In S2634, the CPU of the print controller 202 hides the notification screen displayed in the preceding processing and puts the multifunction device 11 into a print-ready state.

[0152] Figure 26(c) is a flowchart of the notification sequence when the mounting section has a detection means and the transport guide 67, which is an opening / closing member, is locked by the drive member. This notification sequence is initiated when a paper jam occurs in the transport path T.

[0153] In S2642, the CPU of the print controller 202 determines whether there is paper in the relay path TC based on the detection result of the detection means 68. If the result of this step is YES, the process proceeds to S2644. On the other hand, if the result of this step is NO, the process proceeds to S2654.

[0154] In S2644, the CPU of the print controller 202 determines whether there is paper in the mounting section 31 based on the detection result of the mounting medium detection means 87 (see Figures 24 and 25). If the result of this step is YES, the process proceeds to S2646. On the other hand, if the result of this step is NO, the process proceeds to S2650.

[0155] In S2646, the CPU of the print controller 202 issues a notification prompting the user to remove any remaining paper from the paper holder 31. Examples of GUI screens presented to the user in this step include the notification screen 2102 in Figure 21, the notification screen 2202 in Figure 22, and the notification screen 2302 in Figure 23.

[0156] In S2648, the CPU of the print controller 202 determines whether there is paper in the mounting section 31 based on the detection result of the mounting medium detection means 87 (see Figures 24 and 25). If the result of this step is YES, the process returns to S2646. On the other hand, if the result of this step is NO, the process proceeds to S2650.

[0157] In S2650, the CPU of the print controller 202 releases the lock on the transport guide 67, which is an opening / closing member, and issues a notification prompting the resolution of the paper jam in the relay path TC.

[0158] After S2648, if the detection result of the placed medium detection means 87 indicates "no paper in the placement area," the CPU of the print controller 202 controls the drive member to unlock the transport guide 67. Furthermore, if a user input instructing unlocking is received via the GUI screen, the CPU of the print controller 202 may control the drive member to unlock the transport guide 67. In addition, if the detection result of the placed medium detection means 87 indicates "no paper in the placement area" and a user input via the GUI screen is received, the CPU of the print controller 202 may control the drive member to unlock the transport guide 67. In this case, until the detection result of the placed medium detection means 87 indicates "no paper in the placement area," the control disables the button that should be pressed to instruct unlocking the transport guide 67. Specifically, this could involve graying out the OK button on the GUI screen or disabling physical buttons. After these controls unlock the device, the user rotates the transport guide 67 to remove the jammed paper from the relay path TC.

[0159] In S2652, the CPU of the print controller 202 determines whether there is paper in the relay path TC based on the detection result of the detection means 68. If the result of this step is YES, the process returns to S2650. On the other hand, if the result of this step is NO, the process proceeds to S2654.

[0160] In S2654, the CPU of the print controller 202 hides the notification screen displayed in the preceding processing and puts the multifunction device 11 into a print-ready state.

[0161] [Other embodiments] In the embodiments described above, the placed media detection means was shown to detect the presence or absence of media (such as paper) placed on the placement section, but this disclosure is not limited thereto. In other embodiments, the placed media detection means may detect whether or not a predetermined amount or more of media is placed on the placement section. This predetermined amount is an arbitrary value of at least two sheets, for example, 10 sheets, 20 sheets, etc. This predetermined amount is determined relatively based on the size of the placement section, the range of rotation of the transport guide (opening / closing member), etc. For example, if the placed media detection means detects a predetermined amount or more of media, it will issue a notification to remove the remaining media from the placement section. Alternatively, for example, if the amount of media detected by the placed media detection means is a first predetermined amount, it will not issue a notification to remove the remaining media from the placement section, while if the detected amount of media is a second predetermined amount (second predetermined amount > first predetermined amount), it will issue a notification to remove the remaining media.
