[0009] Hereinafter, the embodiments will be described in detail with reference to the attached drawings. Note that the following embodiments do not limit the invention according to the claims. Although the embodiments describe a number of features, not all of these features are essential to the invention, and the features may be combined in any manner. Furthermore, in the attached drawings, the same reference numbers are used for the same or similar configurations, and duplicated descriptions are omitted.

[0010] [First embodiment] FIG. 1 is a diagram showing an example of the internal configuration of an inkjet recording device 1 (hereinafter, recording device 1) used in this embodiment. The recording device 1 is a device equipped with a recording unit, but may also have a function as a multifunction device having a scanner unit. As described below, the recording device 1 is configured to have four paper feed cassettes positioned above and below each other, but the number does not have to be four, and may be one, or five or more. The left side in the figure is the front (front face) of the recording device 1, and the user can pull out each paper feed cassette to the left side in the figure, i.e., to the user's own side.

[0011] Paper feed cassette 2 is the topmost paper feed cassette, with paper feed cassette 3 below paper feed cassette 2, paper feed cassette 4 further below, and paper feed cassette 5 at the bottom. Each of paper feed cassettes 2 to 5 is configured so that a storage portion for storing recording media such as sheets can be slid out from the housing of recording device 1. In the following, unless otherwise specified, paper feed cassette 2 will be described as a representative example of paper feed cassettes 2 to 5.

[0012] Inside the recording device 1, a paper feed roller 6 and a transport roller 12 are configured to transport a sheet along a transport path from when the sheet is fed from the paper feed cassette 2 to when it is discharged, and the paper feed roller 6 is used when picking up a sheet loaded in the paper feed cassette 2. The recording head 10 is a recording unit that performs recording on a sheet by ejecting ink droplets from a nozzle row that corresponds to a color that can be recorded by the recording device 1. The recording head 10 may be a so-called serial type recording head that can reciprocate in a direction perpendicular to the sheet transport direction, or may be a so-called line type recording head configured across the width direction of the sheet.

[0013] For example, when a sheet is stored in the paper feed cassette 2 and printing is started by selecting the paper feed cassette 2, the sheet is picked up by the paper feed roller 6 attached to the paper feed cassette 2 and supplied to the conveying path. The sheet S supplied to the conveying path is conveyed along the conveying path, and the recording head 10 performs recording based on the recording data. In the case of single-sided printing, the sheet S on which recording has been performed is conveyed along the paper discharge path 8 and discharged with the recorded side facing down (face down). On the other hand, in the case of double-sided printing, the sheet S on which recording has been performed is conveyed along the double-sided path by the reversing path 7, and again, the recording head 10 performs recording based on the recording data on the back side. The sheet S is then conveyed along the paper discharge path 8 and discharged.

[0014] The recording device 1 may be configured with a tray capable of supplying a sheet to the conveying path in addition to the paper feed cassettes 2 to 5. For example, the manual feed tray 9 can be set with a type of recording medium desired by the user, and the recording medium can be supplied to the conveying path. In this embodiment, the manual feed tray 9 is positioned so that the user can manually insert a recording medium into the manual feed tray 9 from the front side of the recording device 1. However, the present invention is not limited to this form, and for example, the manual feed tray 9 may be positioned so that the user can manually insert a recording medium into the manual feed tray 9 from the rear side (opposite the front side) of the recording device 1. The operation panel 11 is configured to be able to accept input / output operations for the recording device 1 by the user. The user can instruct operations such as copying and scanning and set a print mode via the operation panel 11. The operation panel 11 also operates as a display unit that displays each piece of information of the recording device 1. The operation panel 11 may include hard keys, or may be configured as a touch panel.

[0015] The recording apparatus 1 in this embodiment is a front conveying type recording apparatus, and the sheet conveying operation will be described later.

[0016] 2 is a block diagram showing the control configuration of the recording apparatus 1. The control configuration includes a print engine unit 200 that mainly controls the print operation, a scanner engine unit 300 that controls the scanner operation, and a controller unit 100 that controls the entire recording apparatus 1. A print controller 202 controls various mechanisms of the print engine unit 200 according to instructions from a main controller 101 of the controller unit 100. Various mechanisms of the scanner engine unit 300 are controlled by the main controller 101 of the controller unit 100. The control configuration will be described in detail below.

[0017] In the controller unit 100, a main controller 101 including a CPU controls the entire recording device 1 using a RAM 106 as a work area in accordance with programs and various parameters stored in a ROM 107. For example, when a print job is input from an external host device 400 such as a PC via a network through a host I / F 102 or a wireless I / F 103, an image processing unit 108 executes a predetermined image processing on the received image data in accordance with an instruction from the main controller 101. Then, the main controller 101 transmits the image data that has been subjected to the image processing to a print engine unit 200 through a print engine I / F 105.

[0018] The recording device 1 may obtain image data from the host device 400 via wireless communication or wired communication, or may obtain image data from an external storage device (such as a USB memory) connected to the recording device 1. There is no particular limitation on the communication method used for wireless communication or wired communication. For example, Wi-Fi (Wireless Fidelity) (registered trademark) or Bluetooth (registered trademark) may be used as a communication method used for wireless communication. Furthermore, USB (Universal Serial Bus) or the like can be used as a communication method used for wired communication. Furthermore, when a read command is input from the host device 400, the main controller 101 transmits the read command to the scanner engine unit 300 via the scanner engine I / F 109.

[0019] The operation panel 104 is a mechanism for receiving input and output from the user to the recording device 1, and corresponds to the operation panel 11 in Fig. 1. Examples of input and output operations from the user include operation instructions such as copying and scanning via the operation panel 104, and the setting of multiple print modes including color printing and monochrome printing. In addition, the operation panel 104 is capable of displaying various user interface screens.

[0020] In the print engine unit 200, a print controller 202 including a CPU controls various mechanisms of the print engine unit 200 using a RAM 204 as a work area according to programs and various parameters stored in a ROM 203. When various commands and image data are received via a controller I / F 201, the print controller 202 temporarily stores them in the RAM 204. The print controller 202 controls an image processing controller 205 to convert the stored image data into print data so that the print head 10 can perform a printing operation. When print data is generated by the conversion, the print controller 202 causes the print head 10 to perform a printing operation via a print head I / F 206. At that time, the print controller 202 drives the conveying roller 12 and the feed roller 6 via a conveying control unit 207 to convey the recording medium S. According to an instruction from the print controller 202, the recording operation by the print head 10 is performed in conjunction with the conveying operation of the recording medium S, and printing processing is performed.

[0021] A carriage control unit 208 changes the orientation and position of the print head 10 depending on the operating state, such as the maintenance state and printing state, of the printing apparatus 1. An ink supply control unit 209 controls an ink supply unit (not shown) so that the pressure of the ink supplied to the print head 10 falls within an appropriate range. A maintenance control unit 210 controls the operation of a cap unit (not shown) and a wiping unit (not shown) when performing a maintenance operation on the print head 10.

[0022] In the scanner engine unit 300, the main controller 101 controls the hardware resources of the scanner controller 302 using the RAM 106 as a work area according to the program and various parameters stored in the ROM 107. This controls various mechanisms of the scanner engine unit 300. For example, the main controller 101 controls the hardware resources in the scanner controller 302 via the controller I / F 301. As a result, a document placed on an ADF (Automatic Document Feeder) by a user is conveyed via a conveyance control unit 304 and read by a sensor 305. The scanner controller 302 then stores image data generated by reading the document in the RAM 303. The print controller 202 can convert the image data acquired as described above into recording data, thereby causing the recording head 10 to perform a recording operation based on the image data read by the scanner controller 302. The recording device 1 is not limited to the configuration shown in FIG. 1 and FIG. 2, and may include appropriate functional blocks that can be executed by a device used as the recording device 1.

[0023] 3 is a diagram for explaining the conveying operation of a sheet picked up by the paper feed cassette of the recording device 1. In the recording device 1, a front conveying type of sheet conveyance is performed. In the front conveying type of sheet conveyance, a sheet picked up by the paper feed cassette is conveyed to the recording head 10 through the pull-out side, i.e., the front side (front surface) of the recording device 1.

[0024] FIG. 3(a) shows a state in which paper feed cassettes 2 to 5 are provided in the recording device 1. The paper feed cassette 2 can be slid in the direction of the arrow by the user pulling out the handle 601. That is, the front of the recording device 1 is, in other words, the face of the recording device 1 on which the handle 601 is provided, and is the face located in the direction in which the paper feed cassette 2 is pulled out. The paper feed cassette 3 can be slid in the direction of the arrow by the user pulling out the handle 602. The paper feed cassette 4 can be slid in the direction of the arrow by the user pulling out the handle 603. The paper feed cassette 5 can be slid in the direction of the arrow by the user pulling out the handle 604. In addition, in the recording device 1 in this embodiment, each paper feed cassette is not provided with a locking mechanism for preventing the paper feed cassette from being pulled out, so that the paper feed cassette can be pulled out even when printing is being performed on a sheet as a recording medium. Note that a locking mechanism may be provided in each paper feed cassette. However, even with such a configuration, when each paper feed cassette is not locked by the locking mechanism, the paper feed cassette can be pulled out even while printing is being performed on a sheet as a recording medium. Note that printing here includes a transport operation that transports a sheet picked up from the paper feed cassette to the recording head 10.

[0025] FIG. 3A shows how a sheet picked up by the paper feed cassette 5 is conveyed to the recording head 10 through the conveying roller 12. Each of the paper feed cassettes has a space near the inner wall of the paper feed cassette on the front side (front side) of the recording device 1. For example, in FIG. 3A, the paper feed cassette 2 has a space 605 near the inner wall of the paper feed cassette on the front side of the recording device 1. The paper feed cassette 3 has a space 606 near the inner wall of the paper feed cassette on the front side of the recording device 1. The paper feed cassette 4 has a space 607 near the inner wall of the paper feed cassette on the front side of the recording device 1. The paper feed cassette 5 has a space 608 near the inner wall of the paper feed cassette on the front side of the recording device 1. The sheet picked up by each paper feed cassette is pushed upward through the above-mentioned space by the conveying force of the paper feed roller 6 and conveyed to the recording head 10. 3(a) shows how a sheet picked up by the paper feed cassette 5 is pushed up to the conveying roller 12 through the spaces 605-607 by the conveying force of the paper feed roller 6, and then conveyed to the recording head 10. That is, as shown in the example of FIG. 3(a), the spaces 605-607 form a part 609 of the conveying path for the sheet, as shown by hatching.

[0026] FIG. 3B is a diagram for explaining that a jam occurs when a user pulls out a paper feed cassette during paper feeding. When a job set to feed paper from the paper feed cassette 5 is executed, the sheet S is transported through a portion 609 of the transport path as shown in FIG. 3A. Here, for example, assume that a user pulls out the paper feed cassette 3 while a sheet picked up from the paper feed cassette 5 is passing through the spaces 605-607. In that case, as shown in FIG. 3B, the portion 609 of the transport path is cut off, causing a jam of the sheet S and preventing printing. That is, the movement path of the upper paper feed cassette, which is the path through which the upper paper feed cassette passes when the upper paper feed cassette is pulled out by the user, overlaps at least a portion of the transport path of the paper supplied from the lower paper feed cassette.

[0027] To prevent the above from happening, it is considered to provide a physical locking mechanism to prevent the user from pulling out the paper feed cassette during printing. However, this requires a configuration for controlling the locking mechanism. It is also considered to provide a conveying path on the rear side of the recording device 1, instead of front-side conveying type sheet conveying. However, in this case, the advantage of front-side conveying type sheet conveying, that is, the conveying path to the recording head 10 can be shortened, is lost.

[0028] In this embodiment, if there is a possibility of an event that may prevent printing, such as a jam, a message screen is displayed to prompt the user not to pull out a paper feed cassette other than the one from which the sheet is picked up. This makes it possible to prevent a jam or the like from occurring due to an unintentional operation by a user to pull out a paper feed cassette.

[0029] Fig. 4 is a flowchart showing a notification process executed in the recording device 1 to prevent the user from pulling out the paper feed cassette during printing. The process in Fig. 4 is realized, for example, by the main controller 101 reading a program stored in the ROM 107 into the RAM 106 and executing it. The process in Fig. 4 is started, for example, when the operation panel 104 receives a user instruction to execute copying, printing, or the like.

[0030] When a printing operation is started, in S101, the main controller 101 specifies which of the sheet storage units will be used in printing. Here, the sheet storage units include the paper feed cassettes 2 to 5 and the manual feed tray 9. For example, the main controller 101 acquires information on a sheet storage unit specified by the user on the operation panel 104. Alternatively, the main controller 101 acquires information on a sheet storage unit set in a job. Also, for example, a paper feed cassette that stores sheets that match the sheet size selected by the user may be specified as the sheet storage unit to be used in printing.

[0031] In S102, the main controller 101 determines the sheet storage unit identified in S101. Then, the process switches depending on the determination result. If the identified sheet storage unit is the first stage (top stage) cassette, that is, the paper feed cassette 2 or the manual feed tray 9, the process proceeds to S103. In S103, the main controller 101 feeds a sheet from the identified sheet storage unit and performs printing without executing control for preventing the user from operating at least one sheet storage unit other than the identified sheet storage unit. This is because even if the user pulls out a paper feed cassette other than the paper feed cassette 2 or the manual feed tray 9, there is no effect on the conveyance of the sheet from the paper feed cassette 2 or the manual feed tray 9. Thus, in this embodiment, if the paper feed cassette 2 or the manual feed tray 9 is identified in S102, the display control of the operation panel 104 such as S104 to S106 described later is not performed.

[0032] If the identified sheet storage unit is the second cassette, that is, the paper feed cassette 3, the process proceeds to S104. When paper is fed from the paper feed cassette 3, if the paper feed cassette 2 located above it is pulled out, a part 609 of the conveying path is cut off, causing a jam or the like. Therefore, in this embodiment, in S104, the main controller 101 executes a first control for preventing the user from operating at least one sheet storage unit other than the identified sheet storage unit. Specifically, the main controller 101 displays a message screen as shown in FIG. 5 on the operation panel 104 to prevent the user from pulling out the paper feed cassette 2. After S104, in S103, the main controller 101 feeds a sheet from the identified sheet storage unit and performs printing.

[0033] FIG. 5 is a diagram showing an example of a screen (message screen) displaying a message urging the user not to pull out the paper feed cassette. In other words, the message urging the user not to pull out the paper feed cassette is a message urging the user not to open the paper feed cassette. As shown in message 501, a message urging the user not to pull out the paper feed cassette and a message notifying the occurrence of an event that hinders printing, such as a jam, are displayed. The message 501 may be continuously displayed during printing, or may be displayed as a pop-up for a predetermined time and may end its display after the predetermined time has elapsed. Also, the display of the screen may end when the user touches the operation panel 104. Also, as described later, in this embodiment, the message screens are displayed in S104, S105, and S106, but the message screens displayed in each step may be different from each other. Specifically, for example, in the message 501, the identification information of the paper feed cassette that may cause a jam if operated by the user may be specified and displayed. Specifically, the identification information of the paper feed cassette 2 is, for example, information indicating the name and position of the paper feed cassette 2. For example, in the case of S104, the sheet feed cassette that may cause a jam if operated by the user is the sheet feed cassette 2. Therefore, the message 501 displayed in S104 is expressed using the identification information of the sheet feed cassette 2. The message 501 may also include the identification information of the sheet storage unit identified in S101. That is, the control for preventing the user from operating at least one sheet storage unit other than the identified sheet storage unit may include the control for preventing the user from operating the identified sheet storage unit. The screen of FIG. 5 may also include a message indicating that an operation may be performed on a sheet storage unit other than the sheet feed cassette that may cause a jam if operated by the user. For example, in the case of S104, the sheet storage units other than the sheet feed cassette that may cause a jam if operated by the user are the sheet feed cassette 4, the sheet feed cassette 5, and the manual feed tray 9.

[0034] If the identified sheet storage unit is the third cassette, that is, the paper feed cassette 4, the process proceeds to S105. When paper is fed from the paper feed cassette 4, if the paper feed cassettes 2 and 3 located above it are pulled out, a part 609 of the conveying path is cut off, causing a jam or the like. Therefore, in this embodiment, in S105, the main controller 101 executes a second control to prevent the user from operating at least one sheet storage unit other than the identified sheet storage unit. Specifically, the main controller 101 displays a message screen as shown in FIG. 5 on the operation panel 104 to prevent the user from pulling out the paper feed cassettes 2 and 3. In the case of S105, the paper feed cassettes that may cause a jam if operated by the user are the paper feed cassette 2 and the paper feed cassette 3. Therefore, the message 501 displayed in S105 is expressed using the identification information of the paper feed cassette 2 and the identification information of the paper feed cassette 3. In addition, in the case of S105, the sheet storage units other than the paper feed cassette that may cause a jam if operated by the user are the paper feed cassette 5 and the manual feed tray 9. Therefore, when the message screen includes a message indicating that an operation may be performed on a sheet storage unit other than the paper feed cassette that may cause a jam if operated by the user, the message is expressed using the identification information of the paper feed cassette 5 and the identification information of the manual feed tray 9. After S105, in S103, the main controller 101 feeds a sheet from the identified sheet storage unit and performs printing.

[0035] If the identified sheet storage unit is the fourth cassette, that is, the sheet feed cassette 5, the process proceeds to S106. When paper is fed from the sheet feed cassette 5, if the sheet feed cassettes 2, 3, and 4 located above it are pulled out, a portion 609 of the conveying path is cut off, causing a jam or the like. Therefore, in this embodiment, in S106, the main controller 101 executes a third control for preventing the user from operating at least one sheet storage unit other than the identified sheet storage unit. Specifically, the main controller 101 displays a message screen as shown in FIG. 5 on the operation panel 104 to prevent the user from pulling out the sheet feed cassettes 2, 3, and 4. In the case of S106, the sheet feed cassettes that may cause a jam if operated by the user are the sheet feed cassette 2, the sheet feed cassette 3, and the sheet feed cassette 4. Therefore, the message 501 displayed in S106 is expressed using the identification information of the paper feed cassette 2, the identification information of the paper feed cassette 3, and the identification information of the paper feed cassette 4. In addition, in the case of S106, the sheet storage unit other than the paper feed cassette that may cause a jam if operated by the user is the manual feed tray 9. Therefore, if the message screen includes a message indicating that an operation may be performed on a paper feed cassette other than the paper feed cassette that may cause a jam if operated by the user, the message is expressed using the identification information of the manual feed tray 9. After S106, in S103, the main controller 101 feeds a sheet from the specified sheet storage unit and performs printing.

[0036] As described above, according to this embodiment, when there is a possibility of an event that may prevent printing, such as a jam, occurring, a message screen is displayed to prompt the user not to pull out a cassette other than the paper feed cassette from which the sheet is picked up. This makes it possible to prevent jams and the like from occurring due to an unintended operation (user operation) of pulling out the paper feed cassette by the user. In addition, in this embodiment, an example has been described in which information about a cassette other than the paper feed cassette from which the sheet is picked up is displayed, but information about the paper feed cassette from which the sheet is picked up may also be displayed.

[0037] In this embodiment, the recording device 1 has been described as a recording device that performs recording by an inkjet recording method. However, the recording device 1 may be a recording device that employs other recording methods, such as an electrophotographic method. The process of FIG. 4 has been described as a display control process that displays the screen shown in FIG. 5. However, it is not limited to display control, and a process of notifying the user of the display contents of FIG. 5 in other forms may be performed. For example, the display contents of FIG. 5 may be performed by voice, or may be performed by distinguishing the display of an LED lamp.

[0038] In the present embodiment, as a control for preventing the user from operating at least one sheet storage unit other than the sheet storage unit specified in S101, different controls are executed according to the type of the sheet storage unit specified in S101. That is, whether the first control, the second control, or the second control is executed is controlled according to the type of the sheet storage unit specified in S101. However, the present invention is not limited to this form, and the control for preventing the user from operating at least one sheet storage unit other than the sheet storage unit specified in S101 may not be different according to the type of the sheet storage unit specified in S101. That is, for example, the same message screen may be displayed in S104, S105, and S106. In this case, a message indicating that an operation may be performed on a paper feed cassette other than the paper feed cassette that may cause a jam if operated by the user may not be included in the message screen. Also, the message 501 may not include identification information of a paper feed cassette that may cause a jam if operated by the user. That is, the message 501 may simply be a message to prevent the user from performing any operation on the paper feed cassette.

[0039] The present invention can also be realized by a process in which a program for implementing one or more of the functions of the above-described embodiments is supplied to a system or device via a network or a storage medium, and one or more processors in a computer of the system or device read and execute the program. The present invention can also be realized by a circuit (e.g., ASIC) that implements one or more of the functions.
