DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Hereinafter, the embodiments of the present invention 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.

[0011] First, the terms used in this embodiment are defined as follows. "Formation" In this specification, "formation" does not only mean the formation of meaningful information such as characters and figures. It does not matter whether it is meaningful or insignificant, and whether it is manifested so that humans can perceive it visually. It also broadly means the formation of an image, pattern, etc. on a recording medium, or the processing of the medium. Furthermore, it does not matter whether it is manifested so that humans can perceive it visually. "Recording medium" Recording medium refers not only to paper used in general image forming devices, but also to cloth, plastic film, metal plate, glass, ceramics, wood, leather, and other materials that can accept ink. "Ink" Ink should be interpreted broadly in the same way as the definition of "formation" above, and refers to a medium including a recording material that can be applied to a recording medium to form an image, pattern, etc., or to process the recording medium, or to treat the ink. It is liquid in terms of physical properties. The ink treatment above refers to, for example, solidification or insolubilization of coloring materials in the ink applied to the recording medium. · "Nozzle" Unless otherwise specified, the term "nozzle" refers to an ejection port. Inside the nozzle there is a communicating liquid path and an element that generates the energy used to eject ink.

[0012] First Embodiment First, a schematic configuration of an image forming apparatus 100 according to a first embodiment will be described with reference to FIGS.

[0013] FIG. 1 is a diagram showing an example of the configuration of a printing system including an image forming apparatus 100 and a host computer 104 according to the first embodiment.

[0014] The image forming apparatus 100 includes an apparatus main body 101 provided with a touch panel 102, and a feed section 103 for mounting and feeding a roll sheet wound into a roll, which is a recording medium. The image forming apparatus 100 prints image data received from a host computer 104 on a label attached to the roll sheet while conveying the roll sheet by a conveying means. As shown in FIG. 1, the image forming apparatus 100 and the host computer 104 are connected via a printer cable 105. Note that, although the first embodiment shows a configuration in which the image forming apparatus 100 and the host computer 104 are connected by the printer cable 105, they may be connected by wireless communication using Wi-Fi (registered trademark) or Bluetooth (registered trademark), etc.

[0015] The operation unit 102 displays software keys on an LCD (liquid crystal) panel 102A (FIG. 3) and can accept information input by contact (touch operation) to a touch operation unit 102B (FIG. 3). That is, the operation unit 102 can input information by displaying software keys and detecting that the software keys have been touched. The panel size of the operation unit 102 according to the first embodiment is 480 pixels×272 pixels. The touch operation unit 102B may be of any of a resistive film type, a capacitive type, and an optical type such as infrared. Here, the touch panel module and the liquid crystal module are described as separate bodies, but they may be integrated as long as input by touch operation is possible. In this embodiment, the touch panel refers to one including both the touch panel module and the liquid crystal module. In this embodiment, "displaying on the touch panel" also includes displaying on the liquid crystal module in a structure in which the touch panel module and the liquid crystal module are provided as separate bodies.

[0016] FIG. 2 is a schematic cross-sectional view illustrating the configuration of the image forming apparatus 100 according to the first embodiment.

[0017] The roll sheet may be a marked sheet with a plurality of marks regularly placed in the conveying direction of the sheet as a recording medium, a continuous roll sheet with no marks, or a label sheet with labels laminated on a roll sheet as a mount. In the following, the image forming apparatus 100 according to the first embodiment will be described taking as an example a case where a roll sheet with marks regularly placed is used as a recording medium.

[0018] As shown in FIG. 2, the image forming apparatus 100 includes an image forming apparatus main body 101 and a feeding section 103. The feeding section 103 includes a roll sheet holder 10A and a pair of roll sheet conveying rollers 10B. The roll sheet M mounted in the roll sheet holder 10A is placed on the pair of roll sheet conveying rollers 10B, and is supplied to the apparatus main body 101 by the rotation of the roll sheet conveying rollers 10B. The apparatus main body 101 includes a conveying section 20 that conveys the roll sheet M, an image forming section 30 that forms an image on the label of the roll sheet, a discharge section 40 that discharges the roll sheet, and a control section 50 (see FIG. 3) that controls the image forming apparatus 100. The apparatus main body 101 also includes a sheet detection sensor 70A and a post-processing sheet detection sensor 80A.

[0019] The conveying section 20 conveys the roll sheet M fed from the feeding section 10 to the image forming section 30 and the discharge section 40 in that order. The image forming section 30 forms an image on the fed roll sheet M. The discharge section 40 cuts the roll sheet M conveyed from the image forming section 30 by the conveying section 20 and discharges it outside the machine. The control section 50 controls the operation of each section of the image forming apparatus 100, such as the feeding section 10, the conveying section 20, the image forming section 30, and the discharge section 40. The configuration of each section will be described in detail below.

[0020] The conveying section 20 has a conveying roller 20A, an endless conveying belt 20B stretched around the conveying roller 20A, and a conveying motor 20C (see FIG. 3) that drives the conveying belt 20B, and is configured to convey the rolled sheet M by the conveying belt 20B. An image forming section 30 is provided at a position facing the conveying surface of the conveying belt 20B that conveys the rolled sheet. A sheet detection sensor 70A is disposed upstream of the image forming section 30 in the sheet conveying direction. The image forming section 30 has a recording head unit 30A and an ink cartridge 30B.

[0021] The recording head unit 30A holds recording heads 30A1, 30A2, 30A3, and 30A4 of each color, each having a plurality of nozzles (6000 in the first embodiment). The recording heads 30A1, 30A2, 30A3, and 30A4 each have a heating element (not shown) built in, and ink is heated by the heating element to eject the ink from the nozzle. The ink cartridges 30B1, 30B2, 30B3, and 30B4 are disposed below the conveyor belt 20B in the device main body 101. The ink cartridges 30B1, 30B2, 30B3, and 30B4 are connected to the recording heads 30A1, 30A2, 30A3, and 30A4 of the corresponding colors by flexible tubes (not shown) or the like, and are configured to supply ink of each color. The maintenance cartridge 30C is a portion for storing ink that is ejected in excess during printing, recovery operations, and the like.

[0022] The sheet detection sensor 70A can detect the leading edge of the rolled sheet M in the transport direction and the position of a mark on the rolled sheet M. This sheet detection sensor 70A detects the leading edge of the rolled sheet M in the transport direction and the presence or absence of a mark on the rolled sheet M before an image is formed by the recording head unit 30A. The sheet detection sensor 70A is disposed at a position upstream of the head unit 30A in the conveying direction. In the case of the first embodiment, the sheet detection sensor 70A is a reflective sensor having a light emitting portion and a light receiving portion disposed on one side of the roll sheet M conveyed by the conveyor belt 20B, and receives light reflected from the light emitting portion toward the conveyor belt 20B by the light receiving portion.

[0023] The discharge section 40 also has a cutter unit 40A and a cutting motor 40B (FIG. 3) that drives the cutter unit 40A. The cutter unit 40A has a cutter 40A1 that can cut the roll sheet M and a lifting mechanism (not shown) that can raise and lower the cutter 40A1 in the vertical direction, and is disposed downstream of the recording head unit 30A in the conveying direction. The cutting motor 40B can raise and lower the cutter 40A1 in the vertical direction by driving the lifting mechanism. The cutting motor 40B is driven by the control section 50 (described later) to cause the lifting mechanism to raise and lower the cutter 40A1, so that the roll sheet M can be cut at a position set by the control section 50 or between any images designated by the user.

[0024] The post-processing sheet detection sensor 80A is disposed at a position upstream of the cutter unit 40A in the transport direction and is a reflective sensor like the sheet detection sensor 70A, and is used to detect the leading edge of the roll sheet M in the transport direction and the presence or absence of a mark on the roll sheet M. The control unit 50 can determine the cutting position by the cutter unit 40A based on the result of sheet detection by the post-processing sheet detection sensor 80A.

[0025] Next, the control unit 50 will be described with reference to FIG.

[0026] FIG. 3 is a block diagram illustrating the configuration of a control unit 50 that controls the apparatus body 101 of the image forming apparatus 100 according to the first embodiment.

[0027] The control unit 50 includes a main controller 50A, a driver controller 50B, a ROM 50C, a RAM 50D, an image buffer memory 50E, a head driving circuit 50F, a driving circuit 50G, and a sensor circuit 50H.

[0028] The main controller 50A controls the entire image forming apparatus 100 and has a function of storing data in the ROM 50C, a function of controlling data, and a function as a setting unit that changes the operation of the main body based on the setting data. The main controller 50A is connected to the host computer 104 and can exchange signals with the host computer 104. The ROM 50C is a memory that is connected to the main controller 50A and stores control programs, and the CPU 300 operates as the main controller 50A using the RAM 50D as a working memory. The main controller 50A is also connected to the touch panel 102, and the user can access the functions of the image forming apparatus 100 using the touch operation unit 102B that can recognize that a software key displayed on the liquid crystal panel 102A has been touched and input information.

[0029] The image buffer memory 50E, which serves as a storage means for recording data, includes image buffer memories 50E1, 50E2, 50E3, and 50E4 for each color, Bk (black), C (cyan), M (magenta), and Y (yellow). The image buffer memory 50E stores image data in bitmap format for each color transmitted from the host computer 104. The head driving circuit 50F is a driving circuit for driving the heating elements (not shown) built into the recording heads 30A1, 30A2, 30A3, and 30A4 of each color. Here, the recording heads 30A1, 30A2, 30A3, and 30A4 are recording heads that eject inks of Bk (black), C (cyan), M (magenta), and Y (yellow). The control unit 50 can form an image using the recording head unit 30A using these configurations. Specifically, a driver controller 50B connected to a main controller 50A controls the driving of the recording head unit 30A via a head driving circuit 50F based on image data stored in an image buffer memory 50E, thereby recording an image.

[0030] The drive circuit 50G can drive the aforementioned conveying motor 20C and cutting motor 40B, and is controlled by the main controller 50A. The sensor circuit 50H includes a sheet detection sensor 70A and a post-processing sheet detection sensor 80A, and the main controller 50A can control the image forming operation, the cutting operation of the roll sheet M, and the like, based on a signal input from the sensor circuit 50H.

[0031] Next, the layout of the display screen displayed on the touch panel of the operation unit 102 of the image forming apparatus 100 will be described with reference to FIGS.

[0032] Fig. 4 is a diagram showing an example of a home screen 400 displayed on the touch panel of the operation unit 102 of the image forming apparatus 100 according to the first embodiment. This home screen 400 is an example of a screen displayed when the image forming apparatus 100 is waiting for an instruction for image formation to be received. In other words, the home screen 400 in Fig. 4 is a screen displayed when the image forming apparatus 100 is in a standby state in which image formation can be started after the image forming apparatus 100 is powered on.

[0033] The home screen (initial screen) 400 has a header section 401 that displays the status of the image forming apparatus 100, the connection line, and the setting status of special printing, and a shortcut key 402 for displaying a screen in which shortcuts for executing functions of the image forming apparatus 100 are registered. It also has an information key 403 that displays help and guidance regarding the image forming apparatus 100, and a menu key 404 that displays an overall menu for setting each function of the image forming apparatus 100. It also includes a backfeed key 405 and a forward feed key 406 related to the transport of the roll sheet M, a cut key 407 that executes cutting of the roll sheet M, and a pause key 408 that temporarily stops the printing process by the image forming apparatus 100. The home screen 400 also includes a consumables remaining amount display section 409 that displays the remaining ink amounts of the installed ink cartridges 30B1, 30B2, 30B3, and 30B4 and the maintenance cartridge 30C, and a counter display section 410 that displays a counter number related to printing.

[0034] On the home screen 400 in FIG. 4, the user can temporarily stop the operation of the image forming apparatus 100 by touching the pause key 408. That is, by touching the pause key 408 to put the image forming apparatus 100 in a paused state (so-called offline state) when no image forming job is being accepted, it is possible to prevent an operation related to image formation from being started immediately even if an image forming job is accepted. For example, by putting the image forming apparatus 100 in a paused state (offline state), it is possible to prevent an image forming operation from being started based on an image forming job transmitted from an external device while the user is touching the menu key 404 or the like to set each function. In this case, the user can touch the pause key 408 before changing the settings, and touch the pause key 408 again after completing the setting change to return the image forming apparatus 100 to an online state, thereby executing the image forming job accepted during the pause.

[0035] Since the home screen 400 in Fig. 4 is before printing has been performed, the header section 401 displays "Printing possible" indicating that printing is possible, and the counter display section 410 displays the number of printed sheets as "0", and the number of jobs indicating the number of jobs executed is also "0". When printing starts on the home screen 400, the screen transitions to the printing screen 500 in Fig. 5. Here, the number of printed sheets refers to the number of labels printed in the case of label sheets, for example.

[0036] 5 is a diagram showing an example of a printing screen 500 displayed on the touch panel of the operation unit 102 of the image forming apparatus 100 according to the embodiment 1. This printing screen 500 is an example of a screen displayed when the image forming apparatus 100 is forming an image.

[0037] In the printing screen 500, the keys related to the control of the roll sheet M displayed in the home screen 400, i.e., the backfeed key 405, the forward feed key 406, and the cut key 407, are hidden. The header section 401, the pause key 408, the consumables remaining amount display section 409, and the job print count display section 501 are displayed. In the printing screen 500, the shortcut keys 402, the information key 403, and the menu key 404 are displayed, but these keys are grayed out and cannot be operated even by touching them. In this embodiment, "hidden" includes a state in which the keys are not displayed on the screen, and a state in which the keys are displayed on the screen but cannot be touched. For example, it also includes a state in which the backfeed key 405, the feed key 406, and the cut key 407 are displayed with other display contents superimposed on them, thereby making it impossible to touch the backfeed key 405, the feed key 406, and the cut key 407.

[0038] The job print count display section 501 displays the number of sheets printed since printing began for the current job up to the present time. The counter display section 410 displays the print speed, the total number of sheets printed, and the number of jobs that have been printed. When the pause key 408 is touched, printing by the image forming apparatus 100 is temporarily stopped, and the transport of the roll sheet M and the image forming operation by the recording heads 30A1, 30A2, 30A3, and 30A4 are temporarily stopped. In this way, when the printing operation of the image forming apparatus 100 is temporarily stopped, the screen transitions to a print stop screen 600 (FIG. 6).

[0039] 6 is a diagram showing an example of a print stop screen 600 displayed on the touch panel of the operation unit 102 of the image forming apparatus 100 according to the embodiment 1. This print stop screen 600 is also an example of a screen displayed when the image forming apparatus 100 is waiting to receive an instruction for image formation.

[0040] The print stop screen 600 includes a header section 401, a shortcut key 402, an information key 403, a menu key 404, a back feed key 405, a forward feed key 406, a cut key 407, and a pause key 408. The print stop screen 600 further includes a print data delete button 601 for deleting print data, and a consumables remaining amount display section 409. In the print stop screen 600, the shortcut key 402, the information key 403, and the menu key 404 are operable, and are therefore displayed in the normal form, similar to the home screen 400. When the shortcut key 402 is touched, the screen transitions to a screen that displays registered shortcuts. When the information key 403 is touched, the screen transitions to a screen that displays help and guidance regarding the image forming apparatus 100. When the menu key 404 is touched, the screen transitions to a menu screen where each function, such as settings of the image forming apparatus 100, can be selected and executed. When the back feed key 405 is touched, the conveying motor 20C is rotated in the opposite direction to the conveying direction during printing, and the conveying belt 20B is operated to rewind the roll sheet M. This allows the user to return the roll sheet M, which is sandwiched between the pair of conveying rollers, to a position where the clamping is released, for example, when replacing the roll sheet M. When the forward feed key 406 is touched, the conveying belt 20B is operated to convey the roll sheet M in the same manner as during printing, even when printing is not in progress. This allows the user to convey the roll sheet M by an arbitrary amount, for example, when installing a roll winding device as a post-processing device downstream of the image forming apparatus 100. When the cut key 407 is touched, the roll sheet M is cut at the current conveying position of the roll sheet and discharged outside the apparatus. When the pause key 408 is touched again on the print stop screen 600, the print process by the image forming apparatus 100 is resumed.

[0041] In this embodiment, the pause key 408 shown in Fig. 4 to Fig. 6 is a pause key for accepting a pause instruction from a user. The pause key 408 is a key for putting the image forming apparatus 100 into an offline state (pause state) on the home screen 400 shown in Fig. 4. 5, it is a software key that receives an instruction to temporarily suspend the image forming operation by the image forming apparatus 100. Moreover, in the printing in progress screen 500 shown in Fig. 6, it is a software key that receives an instruction to resume the image forming operation after the temporary suspension.

[0042] On the home screen 400 in FIG. 4 or the print stop screen 600 in FIG. 6, the user can touch the menu key 404 to set the image forming apparatus 100 or execute each function. FIG. 7 shows a menu screen 700 that is displayed when the menu key 404 is touched. The header of the menu screen 700 includes a home key 701 for moving from the menu screen 700 to the home screen 400, and a back key 702 for moving from the paper remaining amount display setting menu screen 720 to the previous layer. In addition, the menu screen 700 displays item keys of multiple layers such as item keys 703a to 703e of the top layer, and items are classified into multiple layers such as a high layer and a middle layer below that. By touching the item keys of each layer, the user can display item keys of lower layers related to each of the items, and finally display the item keys of the lowest layer to perform settings and execute functions corresponding to the items.

[0043] When a user performs each setting or function, the user must repeat the selection from the menu screen 700 until the lowest level of each item is reached, and the deeper the level of the items, the more complicated the operation becomes, which may impair user operability. Therefore, it is possible to register shortcuts for items selected by the user at will, such as items that the user uses frequently.

[0044] FIG. 8 shows a shortcut screen 800 that is displayed when the shortcut key 402 displayed on the home screen 400 or the print stop screen 600 is touched. The shortcut screen 800 displays a close key 801 for closing the shortcut screen and a page move key 802 for moving pages of the shortcut screen 800. The shortcut screen also displays registered shortcut keys 803a to f. FIG. 8 shows a state in which shortcuts are registered in four of the six shortcut keys, 803a to 803d, and shortcuts are not registered in two shortcut keys, 803e and 803f. When any of the shortcut keys 803a to 803d is touched, the screen transitions to a screen corresponding to the item displayed on each key. For example, when the shortcut key 803a is touched, the screen transitions to a screen for selecting whether or not to display the print speed of the image forming apparatus 100 on the home screen. In this embodiment, six shortcut keys are displayed on one page, but the number of shortcut keys may be five or less, or seven or more.

[0045] As shown in FIG. 8, when there are many shortcuts to be registered, the maximum number of shortcuts that can be registered on the shortcut screen 800 may be exceeded. In addition, when the items are in the same hierarchy, the more shortcuts are registered, the more work the user has to do, and the convenience may decrease. For example, the items corresponding to the shortcut keys 803a to 803d shown in FIG. 8 are all set in the same hierarchy, "home screen display". In this case, if only the lowest hierarchy of item keys can register shortcuts, the convenience of the user may decrease. Therefore, in this embodiment, in order to further improve the convenience of the user, shortcuts can be registered not only for the lowest hierarchy of item keys that can be selected from the menu screen 700, but also for item keys in the middle hierarchy. Details of this will be described below. The following control is performed by the control unit 50 detecting a touch operation by the user via the touch panel.

[0046] Fig. 9 is a flow chart showing the process of registering a shortcut for an item key in a middle hierarchy. When the control unit 50 detects that the user has touched the menu key 402 via the touch panel (S901 Yes), it displays the menu screen 700 shown in Fig. 7. Then, when the system setting item key 703C of the menu screen 700 is pressed (S903 Yes), it displays the system setting menu screen 900 (Fig. 10(a)). Then, when the shortcut registration item key 901c of the item keys 901a to 901e of the system setting menu screen 900 is touched (S905 Yes), it displays a pop-up display 910 (Fig. 10(b)) (S906).

[0047] If the selection key 911a of the selection keys 911a and 911b displayed in the pop-up display 910 is touched (S907 Yes), the mode switches to shortcut registration mode (S908) and displays the shortcut registration screen 920 shown in Fig. 10(c). On the other hand, if the selection key 911b of the selection keys 911a and 911b displayed in the pop-up display 910 is touched (S907 No), the mode returns to S904 and the system setting menu screen 900 is displayed.

[0048] In the shortcut registration mode, when any of the item keys 921a to 921e is pressed and held (S909 Yes), a shortcut registration screen 930 is displayed (S910). The shortcut registration screen 930 displays selection keys 931a to 931d for selecting whether to not register a shortcut or to register the shortcut on one of pages 1 to 3 of the shortcut registration screen 800. When one of the setting keys, selection key 931b to 931d, which relates to page selection on the shortcut registration screen 800, is selected (S911 Yes), the item corresponding to the item key pressed and held in S909 is registered as a shortcut on the shortcut registration screen 800 based on the selected page number (S912), and a pop-up display 940 (FIG. 10(e)) is displayed (S913).

[0049] If the selection key 941a out of the selection keys 941a and 941b displayed in the pop-up display 940 is touched (S914 No), the process returns to S909 and waits until any of the item keys is pressed and held while the shortcut registration screen 920 is displayed. In this case, the shortcut registration screen 920 displayed displays the page number for which the shortcut is registered on the item key 921a of the shortcut registration screen 920, as shown in Fig. 11(a). Fig. 11(a) shows an example in which the selection key 921a is pressed and held on the shortcut registration screen 920 in Fig. 10(c) and a shortcut is registered on Page 1 for an item displayed on the home screen.

[0050] On the other hand, if the selection key 941b of the selection keys 911a and 911b displayed in the pop-up display 940 is touched (S914 Yes), the shortcut registration mode is ended and the normal system setting menu screen 900 is displayed (S915).

[0051] If none of the item keys 921a to 921e has been pressed long in S909, the control unit 50 determines whether any of the item keys 921a to 921e has been pressed short (S916). In this embodiment, a short press refers to a state in which a software key is touched for a time shorter than a long press. For example, the control unit 50 detects a long press when the software key continues to be touched for 1000 ms, and detects a short press when the software key is touched for less than 1000 ms.

[0052] When the control unit 50 detects that any of the item keys 921a to 921e has been pressed for a short time, the control unit 50 displays a menu screen of an item that corresponds to the touched item key (S917). After that, the process returns to S909 and repeats the process.

[0053] When a shortcut is registered in this manner, the shortcut screen 800 that is displayed when the shortcut key 402 is touched on the home screen 400 or the like displays the item for which the shortcut is registered. For example, when a shortcut is registered for an item on the home screen display, as shown in FIG. 11(b), the shortcut key 803a displays the item on the home screen display.

[0054] Next, the process when the shortcut screen is displayed will be described with reference to Fig. 12. Fig. 12 is a flow chart showing the process when transitioning from the shortcut screen to the shortcut registration mode. When the shortcut key 402 is touched on the home screen 400 or the like (S1201 Yes), the control unit 50 displays the shortcut screen 800 (S1202). Then, it is determined whether any of the shortcut keys 803a to 803f is touched on the shortcut screen 800 (S1203).

[0055] When any of shortcut keys 803a-f is touched (S1203 Yes), if there is an item registered to the touched shortcut key (S1204 Yes), the screen of the corresponding item is displayed (S1205). For example, when a shortcut for displaying the home screen is registered as shown in Fig. 11(b) and shortcut key 803a is touched on shortcut screen 800, menu screen 1100 for displaying the home screen is displayed as shown in Fig. 11(c).

[0056] If there is no item registered to the touched shortcut key (S1204 No), the control unit 50 switches to shortcut registration mode (S1206) and displays the shortcut registration screen 920 shown in Fig. 10(c). Note that the shortcut registration mode is similar to the processing contents of S908 to S915 described above, and therefore the description will be omitted.

[0057] If any of the shortcut keys 803a-f has not been touched (S1203 No) but the close key 801 has been touched (S1207 Yes), the shortcut screen 800 is closed and the screen that was displayed before the shortcut key was touched in S1201 is displayed (S1208).

[0058] As described above, for example, by registering a shortcut to the menu screen of the home screen display, the shortcut destination home screen display menu can be easily accessed. Also, compared to registering shortcuts for each of the items displayed on the menu screen of the home screen display as shown in Fig. 8, the time and effort required for shortcut registration can be reduced, improving user convenience.

[0059] In the above embodiment, an example has been shown in which a shortcut is registered for the menu screen of the home screen display, but the same effect can be obtained by registering shortcuts for other items.
