For example, a home screen, a setting screen, and the like are displayed on the display input device (operation unit of the multifunction machine) of Patent Document 1. Note that the home screen is a screen for accepting an instruction to select a function to be used from a plurality of types of functions (such as a copy function) installed in the multifunction peripheral. The setting screen is a screen for accepting a change in setting contents of various setting items such as paper size and density from the user.

  Here, the display input device of Patent Document 1 includes a home key (hardware key). When an operation of pressing the home key is performed, the operation is detected as a home return operation, and the current display screen changes to the home screen.

JP-A-2015-119485

  Depending on the display input device, when it is detected that a home return operation (operation of pressing the home key) is performed, the setting content after the setting item whose setting content has been changed is reset (returns to the default setting content). ) There are things. In other words, when the home return operation is performed on the display input device, the display screen changes to the home screen. At this time, the setting content after changing the setting item whose setting content has been changed is reset.

  In the configuration that resets the setting contents in response to the home return operation in this way, if the user presses the home key accidentally while performing an operation to change the setting contents, the changed setting contents are unintentionally reset. End up. In this case, the operation for changing the setting contents must be performed again from the beginning. For this reason, it is cumbersome and inconvenient for the user.

  The present invention has been made to solve the above-described problem, and includes a display input device capable of improving the convenience of the user when returning the current setting content to the setting content changed last time, and the display input device. An object is to provide an image forming apparatus.

  In order to achieve the above object, the display input device of the present invention displays a home screen, displays a setting screen when accepting a setting operation for changing setting contents, and performs a home return operation while the setting screen is displayed. When accepted, the operation display unit that displays the home screen instead of the setting screen, the display unit that controls the display operation of the operation display unit, the control unit that detects the operation performed on the operation display unit, and the information are stored A storage unit. Then, when a home return operation is performed on the operation display unit while the setting screen is displayed, the control unit sets the target item that is a setting item whose setting content has been changed by the setting operation and the setting after the target item has been changed. After the change history information indicating the content is stored in the storage unit, the setting content of the target item is reset. When a predetermined first operation is performed on the operation display unit while the home screen is displayed, the control unit changes the setting content of the target item to the setting content indicated by the change history information.

  In the configuration of the present invention, when the setting content is changed by displaying the setting screen, the operation detected as the home return operation is mistakenly performed, and thus the changed setting content is reset. If the first operation is performed, the current setting content is changed to the setting content indicated by the change history information. That is, it is possible to return the current setting content to the previously changed setting content simply by performing the first operation. Therefore, there is no need to redo the setting operation from the beginning in order to return the current setting contents to the previously changed setting contents. This improves the convenience of the user when returning the current setting contents to the setting contents changed last time.

  With the configuration of the present invention, it is possible to improve the convenience of the user when returning the current setting content to the setting content that was changed last time.

  Hereinafter, an image forming apparatus according to an embodiment of the present invention will be described taking as an example a multi-function peripheral equipped with a plurality of functions such as a copy function and a transmission function (for example, a fax function).

<Overall configuration of MFP>
As shown in FIG. 1, a multifunction peripheral 100 (corresponding to an “image forming apparatus”) of the present embodiment includes an image reading unit 1 and a printing unit 2. The image reading unit 1 reads a document and generates image data of the document. The printing unit 2 transports the paper along the paper transport path 21. The printing unit 2 forms a toner image based on the image data. Then, the printing unit 2 transfers (prints) the toner image onto the sheet being conveyed.

  The printing unit 2 includes a paper feeding unit 3, a paper transport unit 4, an image forming unit 5, and a fixing unit 6. The paper feed unit 3 includes a pickup roller 31 and a paper feed roller pair 32, and supplies the paper stored in the paper cassette 33 to the paper transport path 21. The paper transport unit 4 includes a plurality of transport roller pairs 41 and transports the paper along the paper transport path 21.

  The image forming unit 5 includes a photosensitive drum 51, a charging device 52, an exposure device 53, a developing device 54, a transfer roller 55, and a cleaning device 56. The image forming unit 5 forms a toner image based on the image data, and transfers the toner image to a sheet. The fixing unit 6 includes a heating roller 61 and a pressure roller 62, and fixes the toner image transferred onto the sheet by heating and pressing.

  In addition, the operation panel 7 is attached to the multifunction device 100. For example, the operation panel 7 is disposed on the front side of the multi-function device 100 (a portion indicated by a broken line in FIG. 1). The operation panel 7 corresponds to a “display input device”.

  As shown in FIG. 2, the operation panel 7 includes an operation display unit 70. The operation display unit 70 includes a touch panel display 71 and hardware keys 72. The hardware key 72 includes a start key for accepting a job start instruction, a stop key for accepting a job stop instruction, and a reset key for accepting a reset instruction for setting contents changed from the default. Further, there is a home key 73 as the hardware key 72. The home key 73 will be described in detail later.

<Hardware configuration of MFP>
As shown in FIG. 3, the multifunction peripheral 100 includes a main control unit 110 and a communication unit 120. The main control unit 110 includes a CPU 111 and a memory 112 (ROM, RAM, etc.). The CPU 111 operates based on a control program and data, and controls each operation of the image reading unit 1 and the printing unit 2. The control program and data are stored in the memory 112 (previously stored in the ROM and expanded in the RAM).

  The communication unit 120 is communicably connected to the external computer 200 via a network. Accordingly, printing can be performed based on the image data transmitted from the computer 200, and image data of the document obtained by reading the document can be transmitted to the computer 200. Further, a modem or the like may be built in the communication unit 120. In this case, it is possible to perform fax communication with an external facsimile 300 via a network such as a telephone line.

  Here, the operation panel 7 includes a panel control unit 710 (panel controller). The panel control unit 710 includes a panel CPU 711 and a panel memory 712 (ROM, RAM, etc.). The panel control unit 710 receives an instruction from the main control unit 110 and controls the display operation of the touch panel display 71. Further, the panel control unit 710 detects a touch operation on the touch panel display 71 and a press operation on the hardware key 72. The panel control unit 710 corresponds to a “control unit”, and the panel memory 712 corresponds to a “storage unit”.

<Operation panel display screen>
The panel control unit 710 displays a home screen 810 as shown in FIG. 4 on the operation display unit 70 as an initial screen. Home screen 810 is a screen for accepting from the user an instruction to select which of a plurality of types of functions such as a copy function and a transmission function is to be used. On the home screen 810, a plurality of function keys 81 (software keys) respectively corresponding to a plurality of types of functions are arranged.

  When an operation is performed on any of the plurality of function keys 81, the panel control unit 710 recognizes a function corresponding to the function key 81 that has been operated as a use function. Then, the panel control unit 710 causes the operation display unit 70 to accept a setting operation for changing setting contents (job execution conditions and the like) related to the job of the function to be used. At this time, the operation display unit 70 displays a setting screen 820 (see FIG. 5).

  For example, when an operation is performed on the copy key among the plurality of function keys 81, a copy screen 821 as shown in FIG. 5 is displayed as the setting screen 820. Although not shown, when an operation is performed on a function key 81 other than the copy key, a setting screen 820 corresponding to the function key 81 is displayed.

  On the copy screen 821, a plurality of item keys 82 (software keys) respectively corresponding to a plurality of setting items such as “paper size” and “density” are arranged. Further, the current setting content of the corresponding setting item is displayed in each display area of the plurality of item keys 82.

  When an operation is performed on any of the plurality of item keys 82, the panel control unit 710 causes the operation display unit 70 to display a detailed setting screen 830 (see FIG. 6). For example, when an operation is performed on the paper size key among the plurality of item keys 82, a paper size setting screen 831 as shown in FIG. 6 is displayed as the detailed setting screen 830. Although not shown, when an operation is performed on an item key 82 other than the paper size key, a detailed setting screen 830 corresponding to the item key 82 is displayed.

  In the paper size setting screen 831, a plurality of paper size setting keys 83 for setting the paper size (paper source) used for printing are arranged. When an operation is performed on the paper size setting key 83 “cassette 1 (A4)” on the paper size setting screen 831, the paper size used for printing can be set to A4 size, and “cassette 2 (B5)” Is operated to the paper size setting key 83, the paper size used for printing can be set to B5 size. For example, by default, the paper size is set to “automatic”.

  In addition, a determination key K is arranged on the detailed setting screen 830 such as the paper size setting screen 831. When an operation is performed on the enter key K, the setting on the detailed setting screen 830 is confirmed.

  When the operation on the enter key K is performed, the panel control unit 710 instructs the operation display unit 70 to change the display screen from the detailed setting screen 830 to the setting screen 820. Further, when an operation is performed on the enter key K, the panel control unit 710 determines whether or not the setting content of the setting item corresponding to the detailed setting screen 830 at that time has been changed from the default. As a result of this determination, if the setting content has been changed from the default, the panel control unit 710 recognizes the setting item whose setting content has been changed from the default as a target item, and rewrites the setting information stored in the panel memory 712. . Note that the setting information is information indicating the current setting contents of each of the plurality of setting items. If any setting contents of the plurality of setting items are changed from the default, a plurality of setting items indicated by the setting information are displayed. The setting contents of the setting item whose setting contents are changed are rewritten to the setting contents after the change.

  For example, assume that the paper size is changed from “automatic (default)” to “A4 size”. In this case, as shown in FIG. 7, the current setting content displayed in the display area of the paper size key among the plurality of item keys 82 is the setting content after changing from “automatic” which is the default setting content. Switch to “A4 size”. That is, the paper size is set to “A4 size”. In FIG. 7, the item key 82 corresponding to the setting item whose setting content has been changed (that is, the paper size) is hatched to be distinguished from the other item keys 82.

  When an operation is performed on the start key (hardware key 72) while the setting screen 820 is displayed, the panel control unit 710 transmits a start notification indicating that a job start instruction has been received to the main control unit 110. . If there is a setting item (target item) whose setting content has been changed from the default, the panel control unit 710 includes the target item and the setting content after the change of the target item in the start notification. For example, the panel control unit 710 determines whether the target item exists based on the setting information.

  When the main control unit 110 receives a start notification from the panel control unit 710, the main control unit 110 sets each of a plurality of setting items related to the job to be executed, and starts the job. At this time, if there is a setting item (target item) whose setting content has been changed from the default, the main control unit 110 sets the setting content of the target item among the plurality of setting items to the setting content after the change.

  For example, assume that while the setting screen 820 is displayed, an operation on the reset key (hardware key 72) is performed before an operation on the start key (hardware key 72). In this case, if there is a setting item (target item) whose setting content is changed from the default, the panel control unit 710 resets the setting content of the target item (the setting content of the target item is changed from the setting content after the change). Return to the setting of That is, the panel control unit 710 changes all setting contents of the plurality of setting items indicated by the setting information (information indicating the current setting contents of the plurality of setting items) to default setting contents. Thereby, the setting content of the setting item (target item) whose setting content has been changed returns to the default. Even when a home return operation described later is performed, the changed setting contents are reset as in the case of performing an operation on the reset key.

<Operation for home key>
(Home return operation)
When an operation of pressing the home key 73 (see FIG. 2) once is performed while the setting screen 820 or the detailed setting screen 830 is displayed, the panel control unit 710 detects the operation as a home return operation. When a home return operation is performed on the operation display unit 70, the panel control unit 710 instructs the operation display unit 70 to change the display screen from the setting screen 820 (or the detailed setting screen 830) to the home screen 810. . At this time, if there is a setting item (target item) whose setting content is changed from the default, the panel control unit 710 resets the setting content of the target item. Thereby, the setting content of the setting item (target item) whose setting content has been changed returns to the default.

  Here, when a home return operation is performed on the operation display unit 70, the panel control unit 710, if there is a setting item (target item) whose setting content has been changed from the default, the target item and the target item. Information indicating the setting contents after the change is stored in the panel memory 712 as change history information 720 (see FIG. 3). The panel control unit 710 stores the change history information 720 in the panel memory 712, resets the setting contents of the target item, and displays the display screen from the setting screen 820 (or the detailed setting screen 830) to the home screen 810. The operation display unit 70 performs the above transition.

  Note that the change history information 720 stored in the panel memory 712 is automatically deleted from the panel memory 712 when a predetermined deletion condition is satisfied. Alternatively, the change history information 720 may be deleted from the panel memory 712 by performing a predetermined deletion operation on the operation display unit 70.

  For example, the panel control unit 710 deletes the change history information 720 from the panel memory 712, assuming that the deletion condition is satisfied when a job executed based on the changed setting content is completed. Further, the panel control unit 710 displays from the setting screen 820 to the home screen 810 when a predetermined time (for example, several seconds to several tens of seconds) has elapsed since the home return operation was performed while the setting screen 820 was being displayed. When a predetermined time elapses after the screen is changed, the change history information 720 is deleted from the panel memory 712, assuming that the deletion condition is satisfied. Furthermore, when the panel control unit 710 transitions the display screen from the home screen 810 to a predetermined screen (a screen different from the setting screen 820 for accepting a change in the setting content of the target item), the deletion condition is satisfied. The change history information 720 is deleted from the panel memory 712.

(First operation and second operation)
Panel control unit 710 determines whether or not a predetermined first operation has been performed during display of home screen 810. For example, when the home key 73 (see FIG. 2) is pressed once while the home screen 810 is displayed, the panel control unit 710 detects the operation as the first operation. That is, if the same operation as the home return operation is performed while the home screen 810 is displayed, the operation is not detected as the home return operation but is detected as the first operation.

  The operation detected as the first operation is not particularly limited. For example, although not shown, a first operation reception key (software key) for receiving the first operation may be arranged in the home screen 810, and the operation on the first operation reception key may be detected as the first operation. Further, when a predetermined operation (for example, a long press operation) is performed on any of the plurality of hardware keys 72 while the home screen 810 is displayed, the operation is detected as the first operation. May be. Alternatively, when the operation on the numeric keypad as the hardware key 72 is performed in a predetermined order while the home screen 810 is displayed, the operation may be detected as the first operation.

  When the first operation is performed on the operation display unit 70, the panel control unit 710 stores the change history information 720 (information indicating the target item and the setting content after the target item is changed) in the panel memory 712. Judge whether or not. If the change history information 720 is stored in the panel memory 712 as a result of this determination, the panel control unit 710 instructs the operation display unit 70 to change the display screen from the home screen 810 to the setting screen 820. For example, the panel control unit 710 causes the operation display unit 70 to display a setting screen 820 for changing the setting content of the target item among the plurality of setting screens 820.

  Further, when the display screen is changed from the home screen 810 to the setting screen 820 in response to the first operation being performed, the panel control unit 710 changes the setting content of the target item to the setting content indicated by the change history information 720. change. That is, the setting contents of the target item among the plurality of setting items indicated by the setting information (information indicating the current setting contents of the plurality of setting items) are rewritten to the setting contents indicated by the change history information 720. In this case, the setting content of the target item returns to the setting content changed last time.

  For example, as shown in FIG. 8, it is assumed that the paper size is changed from “automatic (default)” to “A4 size” and the home return operation is performed in this state. In this case, the panel control unit 710 causes the panel memory 712 to store information indicating that the paper size has been changed to “A4 size” as the change history information 720. Subsequently, the panel control unit 710 resets the setting content of the paper size. That is, the panel control unit 710 returns the setting content of the paper size from “A4 size” to “automatic (default)”. Then, the panel control unit 710 causes the display screen to transition from the copy screen 821 to the home screen 810.

  Thereafter, when the first operation is performed, the panel control unit 710 changes the setting content of the paper size from “automatic (default)” to “A4 size”. Then, the panel control unit 710 causes the display screen to transition from the home screen 810 to the copy screen 821. As a result, the current setting content displayed in the display area of the paper size key (item key 82) is “A4 size”.

  If the change history information 720 is not stored in the panel memory 712 when the first operation is performed, the panel control unit 710 continues to display the home screen 810 that is currently displayed. At this time, as shown in FIG. 9, a notification message MG indicating that the setting content has not been changed may be displayed in a pop-up on the home screen 810.

  Further, panel control unit 710 determines whether or not a predetermined second operation has been performed while home screen 810 is being displayed. For example, when the home key 73 (see FIG. 2) is continuously pressed a plurality of times (for example, twice) while the home screen 810 is displayed, the panel control unit 710 sets the operation as the second operation. Detect. Note that the operation detected as the second operation is not particularly limited as long as the operation is different from the first operation.

  When the second operation is performed on the operation display unit 70, the panel control unit 710 stores the change history information 720 (information indicating the target item and the setting content after the target item is changed) in the panel memory 712. Judge whether or not. If the change history information 720 is stored in the panel memory 712 as a result of this determination, the panel control unit 710 instructs the operation display unit 70 to display the change history (target item and target item of the target item) indicated by the change history information 720. The changed setting content) is displayed on the operation display unit 70. For example, as shown in FIG. 10, the change history list HL showing the target item and the setting contents after the change of the target item is pop-up displayed on the home screen 810.

<Process flow when home key operation is performed>
Hereinafter, the flow of processing when an operation on the home key 73 is performed will be described with reference to the flowchart shown in FIG. The start of the flowchart shown in FIG. 11 starts when the panel control unit 710 detects an operation on the home key 73.

  In step S <b> 1, panel control unit 710 determines whether or not the operation on home key 73 is a home return operation. That is, panel control unit 710 determines whether or not an operation for pressing home key 73 once has been performed while setting screen 820 is displayed. As a result, when the panel control unit 710 determines that the home return operation has been performed, the process proceeds to step S2.

  In step S2, the panel control unit 710 determines whether there is a target item that is a setting item whose setting content has been changed from the default. As a result, when the panel control unit 710 determines that the target item exists, the process proceeds to step S3. In step S3, the panel control unit 710 causes the panel memory 712 to store the change history information 720 indicating the target item and the setting content after the change of the target item. Thereafter, in step S4, the panel control unit 710 resets the setting content of the target item.

  In step S5, the panel control unit 710 causes the operation display unit 70 to display the home screen 810 (the display screen is changed from the setting screen 820 to the home screen 810). If the panel control unit 710 determines in step S2 that the target item does not exist, steps S3 and S4 are omitted, and the process proceeds to step S5.

  If the panel control unit 710 determines in step S1 that the operation on the home key 73 is not a home return operation, the process proceeds to step S6. In step S6, the panel control unit 710 determines whether or not the operation on the home key 73 is the first operation. That is, panel control unit 710 determines whether or not an operation of pressing home key 73 once is performed while home screen 810 is displayed. As a result, when the panel control unit 710 determines that the first operation has been performed, the process proceeds to step S7.

  In step S7, the panel control unit 710 determines whether or not the change history information 720 (information indicating the target item and the setting contents after the change of the target item) is stored in the panel memory 712. As a result, when the panel control unit 710 determines that the change history information 720 is stored in the panel memory 712, the process proceeds to step S8.

  In step S8, the panel control unit 710 changes the setting content of the target item based on the change history information 720. As a result, the setting content of the target item is changed from the default setting content to the setting content indicated by the change history information 720. Thereafter, in step S9, the panel control unit 710 causes the operation display unit 70 to display the setting screen 820 (the display screen is changed from the home screen 810 to the setting screen 820).

  If the panel control unit 710 determines in step S7 that the change history information 720 is not stored in the panel memory 712, the process proceeds to step S10. In step S10, the panel control unit 710 causes the operation display unit 70 to display a notification message MG (see FIG. 9). Note that display of home screen 810 continues (notification message MG pops up on home screen 810). For example, the display of the notification message MG may be stopped when a predetermined time has elapsed from the start of display of the notification message MG. Alternatively, the display of the notification message MG may be stopped in response to a predetermined stop operation being performed on the operation display unit 70.

  In step S6, when the panel control unit 710 determines that the operation on the home key 73 is not the first operation (operation for pressing the home key 73 once), the process proceeds to step S11. In step S11, the panel control unit 710 determines whether the operation on the home key 73 is the second operation. That is, panel control unit 710 determines whether or not an operation of continuously pressing home key 73 a plurality of times during display of home screen 810 has been performed. As a result, when the panel control unit 710 determines that the second operation has been performed, the process proceeds to step S12.

  In step S12, the panel control unit 710 determines whether or not the change history information 720 (information indicating the target item and the setting content after the target item is changed) is stored in the panel memory 712. As a result, when the panel control unit 710 determines that the change history information 720 is stored in the panel memory 712, the process proceeds to step S13. When the panel control unit 710 determines that the change history information 720 is not stored in the panel memory 712, the process proceeds to step S10.

  When the process proceeds to step S13, the panel control unit 710 causes the operation display unit 70 to display the change history list HL (see FIG. 10). Note that the display of the home screen 810 is continued (the change history list HL is popped up on the home screen 810). For example, the display of the change history list HL may be stopped when a predetermined time has elapsed from the start of display of the change history list HL. Alternatively, the display of the change history list HL may be stopped in response to a predetermined stop operation being performed on the operation display unit 70.

  In step S11, when the panel control unit 710 determines that the operation on the home key 73 is not the second operation (operation for continuously pressing the home key 73 a plurality of times), the process proceeds to step S14. In step S14, the panel control unit 710 continues displaying the currently displayed screen.

  The operation panel 7 (display input device) of the present embodiment displays the home screen 810 as described above, and displays the setting screen 820 when accepting a setting operation for changing the setting contents. When a home return operation is received during the display, the operation display unit 70 that displays the home screen 810 instead of the setting screen 820 and the display operation of the operation display unit 70 are controlled, and the operation display unit 70 is performed. A panel control unit 710 (control unit) that detects an operation and a panel memory 712 (storage unit) that stores information are provided. When a home return operation is performed on the operation display unit 70 while the setting screen 820 is displayed, the panel control unit 710 displays the target item and the target item that are setting items whose setting contents have been changed by the setting operation. After the change history information 720 indicating the setting contents after the change is stored in the panel memory 712, the setting contents of the target item are reset. When the first operation (operation of pressing the home key 73 once) is performed on the operation display unit 70 while the home screen 810 is displayed, the panel control unit 710 changes the setting contents of the target item in the change history. The setting is changed to the setting content indicated by the information 720.

  In the configuration of the present embodiment, when the setting content is changed by displaying the setting screen 820, an operation detected as a home return operation is erroneously performed, and the changed setting content is thereby reset. If the first operation is performed, the current setting content is changed to the setting content indicated by the change history information 720. That is, it is possible to return the current setting content to the previously changed setting content simply by performing the first operation. Therefore, there is no need to redo the setting operation from the beginning in order to return the current setting contents to the previously changed setting contents. This improves the convenience of the user when returning the current setting contents to the setting contents changed last time.

  In the present embodiment, as described above, the panel control unit 710 performs the same operation as the home return operation (operation of pressing the home key 73 once) on the operation display unit 70 while the home screen 810 is displayed. When performed, the operation is detected as the first operation. With this configuration, it is possible to return the current setting contents to the previously changed setting contents only by performing a simple operation of pressing the home key 73 once.

  In the present embodiment, as described above, the panel control unit 710 performs a second operation (an operation of continuously pressing the home key 73 a plurality of times) on the operation display unit 70 while the home screen 810 is displayed. When it is performed, the operation item display unit 70 displays the target item and the setting contents after the change of the target item. In this configuration, when returning the current setting contents to the setting contents changed last time, the setting contents changed last time can be confirmed in advance, so that the convenience for the user is further improved.

  In the present embodiment, as described above, the panel control unit 710 deletes the change history information 720 from the panel memory 712 when a predetermined deletion condition is satisfied. In this configuration, it is possible to prevent the change history information 720 from being stored in the panel memory 712 unnecessarily.

  It should be thought that embodiment disclosed this time is an illustration and restrictive at no points. The scope of the present invention is shown not by the description of the above-described embodiment but by the scope of claims for patent, and further includes meanings equivalent to the scope of claims for patent and all modifications within the scope.

  For example, in the above-described embodiment, an example in which the present invention is applied to an operation panel of a multifunction peripheral has been described. However, the present invention can also be applied to an operation panel attached to an apparatus other than the multifunction peripheral, and an information terminal such as a smartphone or a tablet terminal. It is also applicable to.
