In the image forming apparatus 10, a color or monochrome image is formed on a sheet supplied from the paper supply unit 4, and the sheet after image formation is discharged to the discharge tray.

  The control unit 5 includes control devices such as a CPU, a ROM, a RAM, and an EEPROM (registered trademark) not shown. The CPU is a processor that executes various arithmetic processing. The ROM is a nonvolatile storage device in which information such as a control program for causing the CPU to execute various processes is stored in advance. The RAM is a volatile storage device, and the EEPROM is a nonvolatile storage device. The RAM and the EEPROM are used as a temporary storage memory (work area) for various processes executed by the CPU. In the control unit 5, various control programs stored in the ROM in advance are executed by the CPU. Thus, the control unit 5 controls the image forming apparatus 10 as a whole. The control unit 5 may be configured by an electronic circuit such as an integrated circuit (ASIC), and is a control unit provided separately from the main control unit that controls the image forming apparatus 10 in an integrated manner. You may.

  The operation display unit 6 is a user interface in the image forming apparatus 10. As shown in FIGS. 2 and 3, the operation display unit 6 includes a display unit 61, a touch panel 62, and hard keys 63.

  The display unit 61 displays various information according to a control instruction from the control unit 5. For example, the display unit 61 is a liquid crystal display.

The touch panel 62 may detect the contact between the object and the display unit 61 using another detection method such as a capacitance method.

  The hard key 63 inputs various information to the control unit 5 in accordance with a user operation. For example, the hard keys 63 include a power key used to control power supply to each unit of the image forming apparatus 10 and a start key used to instruct execution of various jobs.

[Configuration of Control Unit 5]
Next, the configuration of the control unit 5 will be described in detail with reference to FIGS. Here, FIG. 4 is a diagram showing a relationship between a display screen G1 displayed on the display unit 61 and a display target T1 partially displayed on the display screen G1. FIGS. 5 to 7 are diagrams showing the relationship between the plurality of divided screens G11 to G12 displayed on the display unit 61 and the display target T1.

  As illustrated in FIG. 2, the control unit 5 includes a display processing unit 51, a first movement processing unit 52, a divided display processing unit 53, a second movement processing unit 54, a prohibition processing unit 55, a release processing unit 56, and a display. It includes a change unit 57.

  Specifically, in the ROM of the control unit 5, a display control program for causing the CPU of the control unit 5 to execute a display control process (see a flowchart of FIG. 8) described later is stored in advance. The CPU of the control unit 5 executes the display control program stored in the ROM. Thereby, the control unit 5 functions as the display processing unit 51, the first movement processing unit 52, the divided display processing unit 53, the second movement processing unit 54, the prohibition processing unit 55, the release processing unit 56, and the display change unit 57. I do. The display control program may be recorded on a computer-readable recording medium such as a CD, a DVD, or a flash memory, and may be installed from the recording medium into a storage device such as the EEPROM of the control unit 5.

  The display processing unit 51 causes the display unit 61 to display a display screen G1 (see FIG. 4) displaying a part of the display target T1 (see FIG. 4) having a size exceeding the displayable size of the display unit 61.

  For example, the display target T1 is an image whose length in the vertical direction D1 (see FIG. 3) exceeds the displayable size of the display unit 61. The display target T1 may be an image whose length in the left-right direction D2 (see FIG. 3) exceeds the displayable size of the display unit 61. The display target T1 may be an image whose length in both the vertical direction D1 and the horizontal direction D2 exceeds the displayable size of the display unit 61.

  For example, the display target T1 is an icon display image in which a plurality of icon images corresponding to a plurality of setting items related to a print process executed by the image forming apparatus 10 are displayed, and the print process displayed before the print process is executed. , A preview image showing an image of a printed matter, a web page, and the like.

  For example, the display screen G1 is a screen having the same size as the displayable size of the display unit 61 or a size smaller than the displayable size of the display unit 61. For example, the display screen G1 displays a partial area including the upper end of the display target T1 in the vertical direction D1.

  The first movement processing unit 52 moves the display range A1 (see FIG. 4) displayed on the display screen G1 of the display target T1 (see FIG. 4) according to a predetermined movement operation.

  For example, the moving operation is an operation in which the user brings the object into contact with the display unit 61 and slides a touch position on the display unit 61 with the object in the vertical direction D1 on the display unit 61 (see FIG. 4). ). Note that the moving operation may be an operation in which the user brings the object into contact with the display unit 61 and slides a touch position on the display unit 61 with the object in the left-right direction D2 on the display unit 61. Further, the moving operation may be an operation in which a user brings the object into contact with the display unit 61 and slides a touch position on the display unit 61 with the object in any one direction on the display unit 61. . Further, the moving operation may be an operation on the hard key 63.

  By the way, when the user of the image forming apparatus 10 checks a part of the display target T1 (see FIG. 4) displayed on the display unit 61, the user of the image forming apparatus 10 may display another display target T1 not displayed on the display unit 61. Sometimes you want to refer to some of the contents in parallel. In this case, the user scrolls the display range A1 in the display target T1 between the portions of the display target T1 whose contents are to be checked in parallel by the moving operation.

  However, the operation of reciprocating the display range A1 in the display target T1 between each of the portions in the display target T1 where the contents are desired to be checked in parallel is troublesome for the user. When such an operation is performed during the execution of the printing process, the processing load on the CPU of the control unit 5 may increase, and the execution speed of the printing process may decrease.

  On the other hand, in the image forming apparatus 10 according to the embodiment of the present invention, as described below, it is possible to reduce the trouble of the user's operation and reduce the processing load of the CPU.

  The split display processing unit 53 causes the display unit 61 to display a plurality of split screens G11 to G12 (see FIG. 5) each displaying at least a part of the display target T1 according to a predetermined split operation.

  Specifically, the divided display processing unit 53 causes the display unit 61 to display a plurality of divided screens G11 to G12 each displaying a part of the display content of the display screen G1 instead of the display screen G1.

  For example, in the division operation, the user makes the object touch the display unit 61, and the touch state between the display unit 61 and the object is determined in advance while the touch position on the display unit 61 with the object is fixed. This is an operation to continue beyond the reference time (see FIG. 5). Note that the division operation is, for example, an operation of tapping an arbitrary position on the display unit 61 a plurality of times (touching the display unit 61 to separate the object from the display unit 61 within a predetermined time). You may. Further, the division operation may be an operation on the hard key 63.

  For example, when the division operation is detected by the touch panel 62, the division display processing unit 53 determines a division line L1 (see FIG. 5) along the left-right direction D2 passing through the position on the display unit 61 where the division operation is performed. ) Is displayed. Then, the divided display processing unit 53 displays the divided screen G11 in an area above the division line L1 on the display unit 61. Further, the split display processing unit 53 displays the split screen G12 in an area below the split line L1 on the display unit 61. The split display processing unit 53 may cause the display unit 61 to display three or more split screens according to the split operation.

  For example, the divided screen G11 has a display area of the same size or smaller than the area above the division line L1 on the display screen G1. For example, among the display contents of the display screen G1 at the time of the division operation, display contents above the division line L1 are displayed on the divided screen G11.

  Further, the divided screen G12 has a display area of the same size as or smaller than the area below the division line L1 on the display screen G1. For example, among the display contents of the display screen G1 at the time of the division operation, display contents below the division line L1 are displayed on the divided screen G12.

  The entire display target T1 may be displayed on one of the divided screens G11 and G12. For example, on the split screen G12, the display target T1 reduced to a size that fits in the displayable size of the split screen G12 may be displayed. The display contents of the divided screen G11 and the divided screen G12 may be the same. Further, the total size of the divided screens G11 and G12 may exceed the size of the display screen G1. Further, the entire display content of the display screen G1 may be displayed on one or both of the divided screen G11 and the divided screen G12.

  The second movement processing unit 54 moves the display range corresponding to any one of the divided screens in the display target T1 according to the movement operation. Here, the second movement processing unit 54 is an example of the movement processing unit in the present invention.

  Specifically, when the moving operation to the divided screen G11 is detected by the touch panel 62, the second movement processing unit 54 corresponds to the divided screen G11 in the display target T1 according to the detected moving operation. The display range A11 (see FIG. 5) is moved. When the touch panel 62 detects the movement operation to the divided screen G12, the second movement processing unit 54 displays a display range corresponding to the divided screen G12 in the display target T1 according to the detected movement operation. A12 (see FIG. 5) is moved.

  The prohibition processing unit 55 prohibits the movement of the display range corresponding to the specified divided screen specified by the specifying operation on the display target T1 according to the specifying operation for specifying any one of the divided screens.

  For example, the designation operation is the tap operation on the display area of the designated divided screen, which is performed while the touch state between the display unit 61 and the object in the division operation is continued (see FIG. 6). ). Note that the designation operation may be an operation performed after the division operation. Further, the division operation may be an operation on the hard key 63.

  Here, the prohibition processing unit 55 prohibits the movement of the display range corresponding to the specified divided screen in the display target T1, and prohibits the execution of a part of the process according to the operation input on the specified divided screen. For example, the prohibition processing unit 55 prohibits execution of a process corresponding to an operation other than a release operation described later on the specified divided screen. For example, when the display target T1 is the icon display image, execution of a process according to an operation on the icon image included in the designated divided screen is prohibited. Note that the prohibition processing unit 55 may prohibit execution of all processes according to the operation input on the designated divided screen. Further, the prohibition processing unit 55 does not have to prohibit the execution of the processing according to the operation input on the specified divided screen.

  Further, the prohibition processing unit 55 displays the specified divided screen so that it can be identified. For example, the prohibition processing unit 55 displays an identification image M1 (see FIG. 6) used for identifying the specified divided screen in the area of the specified divided screen according to the specifying operation. Note that the prohibition processing unit 55 may change the brightness, density, color tone, transparency, and the like in the display area of the designated divided screen on the display unit 61 to display the designated divided screen in an identifiable manner. In addition, the prohibition processing unit 55 does not have to display the specified divided screen in an identifiable manner.

  When a plurality of split screens are displayed by the split display processing unit 53, the prohibition processing unit 55 prohibits the movement of the display range corresponding to one predetermined split screen among the split screens. Is also good. For example, when the divided screen G11 and the divided screen G12 are displayed by the divided display processing unit 53, the prohibition processing unit 55 may always prohibit the movement of the display range in the display target T1 corresponding to the divided screen G11.

  The release processing unit 56 causes the display unit 61 to display the display screen G1 instead of a plurality of divided screens according to a predetermined release operation.

  For example, the release operation is an operation in which the user brings the object into contact with the display area of the identification image M1 on the display unit 61 and moves the touch position on the display unit 61 with the object in the upward direction D11 or the downward direction D12. (See FIG. 7). Note that, in the release operation, the user brings the object into contact with an arbitrary position in the display area of the designated divided screen on the display unit 61, and changes the touch position on the display unit 61 with the object in the upward direction D11 or the downward direction D12. It may be an operation of moving to. Further, the release operation may be an operation of moving a touch position on the display unit 61 with the object in a direction different from the vertical direction D1. Further, the release operation may be an operation on the hard key 63.

  Here, the release processing unit 56 replaces the plurality of divided screens with the display screen G1 including the display content of any one of the plurality of divided screens specified based on the moving direction of the release operation. It is displayed on the display unit 61.

  For example, when the moving direction of the release operation is the upward direction D11 (see FIG. 7), the release processing unit 56 displays the display screen G1 including the display content of the divided screen G12 on the display unit 61. When the moving direction of the release operation is the downward direction D12 (see FIG. 7), the release processing unit 56 causes the display unit 61 to display the display screen G1 including the display content of the divided screen G11.

  Note that the relationship between the moving direction of the release operation and one specified split screen may be different from the relationship described above. Further, the cancellation processing unit 56 may cause the display unit 61 to display a display screen G1 including the display content of one predetermined split screen among the plurality of split screens. For example, the release processing unit 56 may cause the display unit 61 to always display the display screen G1 including the display content of the divided screen G11 when the release operation is performed.

  The display change unit 57 changes the display content of the split screen different from the specified split screen to a content different from part or all of the display content of the display screen G1 according to the specifying operation.

  For example, the display change unit 57 sets the display range corresponding to the divided screen different from the designated divided screen specified by the designated operation on the display target T1 to the display screen G1 at the time of the divided operation on the display target T1. Move to a position adjacent to the display range A1. For example, when the split screen G11 is specified as the specified split screen, the display changing unit 57 changes the display range A12 corresponding to the split screen G12 in the display target T1 to the display range A1 of the display screen G1 during the split operation. It is moved to a position adjacent to the display range A1 below (see FIG. 4). When the divided screen G11 is designated as the designated divided screen, the display change unit 57 may move the display range A12 to a position separated from the display range A1 of the display screen G1 at the time of the division operation. .

  The display change unit 57 may change the display content of a split screen different from the specified split screen to content related to the display content of the specified split screen.

  For example, when the display content of the specified split screen includes a predetermined specific image, the display changing unit 57 may change the display content of the split screen different from the specified split screen into a related image associated with the specific image. You may change to the content containing an image. For example, it is conceivable to set each of the icon images as one or both of the specific image and the related image based on the mutual relevance of the setting contents of each of the icon images included in the icon display image. .

  Further, when character information can be extracted from the display content of the specified split screen, the display change unit 57 changes the display content of the split screen different from the specified split screen to the specified split screen of the display target T1. May be changed to the contents of a range including a part or all of the extracted character information outside the display range to be displayed.

  Note that the control unit 5 may not include one or both of the prohibition processing unit 55 and the display change unit 57.

[Display control processing]
Hereinafter, an example of a procedure of a display control process executed by the control unit 5 in the image forming apparatus 10 will be described with reference to FIG. Here, steps S11, S12,... Represent the numbers of the processing procedures (steps) executed by the control unit 5. The display control process is performed when the display target T1 is displayed on the display unit 61 in response to a user operation.

<Step S11>
First, in step S11, the control unit 5 causes the display unit 61 to display the display screen G1 (see FIG. 4). Here, the process of step S11 is executed by the display processing unit 51 of the control unit 5.

<Step S12>
In step S12, the control unit 5 determines whether or not the moving operation to the display screen G1 has been detected.

  Here, when determining that the moving operation to the display screen G1 has been detected (Yes in S12), the control unit 5 shifts the processing to step S13. If the moving operation to the display screen G1 has not been detected (No in S12), the control unit 5 shifts the processing to step S14.

<Step S13>
In step S13, the control unit 5 moves the display range A1 corresponding to the display screen G1 on the display target T1 according to the moving operation detected in step S12. Here, the process of step S13 is executed by the first movement processing unit 52 of the control unit 5.

<Step S14>
In step S14, the control unit 5 determines whether or not the division operation has been detected.

  Here, when determining that the division operation has been detected (Yes in S14), the control unit 5 shifts the processing to step S15. If the division operation has not been detected (No in S14), the control unit 5 shifts the processing to step S16.

<Step S15>
In step S15, the control unit 5 executes a screen division process described later.

<Step S16>
In step S16, the control unit 5 determines whether an operation different from the moving operation and the division operation has been detected. For example, when the display object T1 displayed on the display screen G1 is the icon display image and the operation on the icon image displayed on the display screen G1 is detected, the control unit 5 performs the moving operation. It is determined that an operation different from the division operation has been detected.

  Here, when the control unit 5 determines that an operation different from the movement operation and the division operation has been detected (Yes in S16), the process proceeds to step S17. If an operation different from the movement operation and the division operation has not been detected (No in S16), the control unit 5 shifts the processing to step S18.

<Step S17>
In step S17, the control unit 5 executes a process corresponding to the operation detected in step S16. For example, when an operation on the icon image is detected, the control unit 5 executes a process corresponding to the operated icon image.

<Step S18>
In step S18, the control unit 5 determines whether or not a user operation for instructing termination of the display control process has been detected.

  Here, when the control unit 5 determines that a user operation instructing the end of the display control process has been detected (Yes in S18), the control unit 5 ends the display control process. If the user operation for instructing the end of the display control processing has not been detected (No in S18), the control unit 5 shifts the processing to step S12. Then, the control unit 5 accepts the moving operation, the dividing operation, and an operation different from the moving operation and the dividing operation until a user operation instructing the end of the display control process is detected.

[Screen division processing]
Next, an example of a procedure of the screen division process executed in step S15 of the display control process will be described with reference to FIG. Note that, when a user operation for instructing the end of the display control process is detected during the execution of the screen split process, the screen split process is ended together with the display control process.

<Step S21>
First, in step S21, the control unit 5 causes the display unit 61 to display the divided screen G11 and the divided screen G12 (see FIG. 5). Here, the process of step S21 is executed by the divided display processing unit 53 of the control unit 5.

<Step S22>
In step S22, the control unit 5 determines whether the designation operation is detected together with the division operation.

  Here, when the control unit 5 determines that the designation operation is detected together with the division operation (Yes in S22), the process proceeds to step S23. If the designation operation is not detected together with the division operation (No in S22), the control unit 5 shifts the processing to step S27.

<Step S23>
In step S23, the control unit 5 prohibits movement of the display range corresponding to the specified divided screen specified by the specifying operation on the display target T1. This prevents the display range of the specified divided screen from being erroneously moved at the time of the moving operation to the divided screen different from the specified divided screen in the display target T1.

<Step S24>
In step S24, the control unit 5 prohibits the execution of a part of the process according to the operation input on the designated divided screen designated by the designated operation. Thereby, at the time of the movement operation to the divided screen different from the designated divided screen in the display target T1, the icon image or the like on the designated divided screen is erroneously operated, and a process not intended by the user is executed. Is avoided.

<Step S25>
In step S25, the control unit 5 displays the specified divided screen specified by the specifying operation in an identifiable manner. For example, the control unit 5 displays an identification image M1 (see FIG. 6) on the specified divided screen. Here, the processing of steps S23 to S25 is executed by the prohibition processing unit 55 of the control unit 5.

<Step S26>
In step S26, the control unit 5 changes the display content of the split screen different from the specified split screen specified by the specifying operation to a content different from a part of the display content of the display screen G1. Here, the process of step S26 is executed by the display changing unit 57 of the control unit 5.

  For example, the control unit 5 moves the display range corresponding to the split screen different from the designated split screen on the display target T1 to a position adjacent to the display range A1 corresponding to the display screen G1 at the time of the split operation on the display target T1. Move. Thereby, the display range corresponding to the split screen different from the designated split screen in the display target T1 is the display range A1 corresponding to the display screen G1 at the time of the split operation in the display target T1 whose contents have already been confirmed by the user. Moved outward. Therefore, the trouble of the user's operation of searching for a portion including the content to be referred to in parallel with the content included in the specified divided screen is reduced.

  In the screen division processing, the processing of steps S22 to S26 may be omitted.

<Step S27>
In step S27, the control unit 5 determines whether the moving operation to any one of the divided screen G11 and the divided screen G12 is detected.

  Here, when the control unit 5 determines that the moving operation to any one of the divided screen G11 and the divided screen G12 is detected (Yes in S27), the control unit 5 shifts the processing to step S28. If the moving operation to any one of the divided screens G11 and G12 has not been detected (No in S27), the control unit 5 shifts the processing to step S29.

<Step S28>
In step S28, the control unit 5 moves the display range corresponding to the divided screen G11 or the divided screen G12 in the display target T1 according to the moving operation detected in step S27. Here, the process of step S28 is executed by the second movement processing unit 54 of the control unit 5.

<Step S29>
In step S29, the control unit 5 determines whether an operation different from the moving operation and the division operation has been detected, as in step S16 of the display control process.

  Here, when the control unit 5 determines that an operation different from the moving operation and the division operation has been detected (Yes in S29), the process proceeds to step S30. If an operation different from the movement operation and the division operation has not been detected (No in S29), the control unit 5 shifts the processing to step S31.

<Step S30>
In step S30, the control unit 5 executes a process corresponding to the operation detected in step S29, similarly to step S17 of the display control process.

<Step S31>
In step S31, the control unit 5 determines whether or not the release operation has been detected.

  Here, when determining that the release operation has been detected (Yes in S31), the control unit 5 shifts the processing to step S32. If the release operation has not been detected (No in S31), the control unit 5 shifts the processing to step S27.

<Step S32>
In step S32, the control unit 5 causes the display unit 61 to display the display screen G1 instead of the divided screen G11 and the divided screen G12 in accordance with the release operation detected in step S31. Here, the process of step S32 is executed by the release processing unit 56 of the control unit 5.

  For example, the control unit 5 causes the display unit 61 to display the display screen G1 including the display content of any one of the divided screens G11 and G12 specified based on the moving direction of the release operation. . Thereby, the user can select the display content of the display screen G1 after the release operation by an intuitive operation.

  As described above, in the display control process, the split screen G11 and the split screen each displaying a part of the display target T1 are replaced with the display screen G1 displaying a part of the display target T1 in accordance with the split operation. G12 is displayed on the display unit 61. Therefore, the display range A1 in the display target T1 can reduce the user's operation time and the CPU as compared with the case where the user in the display target T1 reciprocates between each place where the user wants to check the contents in parallel. Can be reduced.
