<1-2. Operation>
In this embodiment, the mode change from the normal display mode MD1 to the enlarged display mode MD2 when an enlargement instruction with an enlargement display magnification larger than a predetermined threshold is given by an enlargement operation (specifically, a pinch out operation). An example in which is automatically performed is illustrated.

  3 and 4 are diagrams showing a display screen (setting screen) GA1 (GA10, GA12) in the normal display mode MD1. When the color setting button BN2 is pressed among the setting item selection buttons BN1 to BN7 on the initial screen GA1 (GA10) of FIG. 3, a menu setting screen (color setting) as shown in FIG. Screen) GA1 (GA12) is displayed on the touch panel 25. In FIG. 4, color settings having five options of “auto color”, “full color”, “black”, “two color”, and “single color” (specifically, buttons BT1 to BT5 corresponding to the option). The screen is displayed. In FIG. 4, for simplification of illustration, the periphery of the touch panel 25 is omitted and only the inside of the touch panel 25 is shown (the same applies to FIG. 5 and subsequent figures).

  When the operator performs an enlargement operation (pinch-out operation) while the setting screen GA12 of FIG. 4 is displayed, the following two types are performed depending on whether or not the enlargement operation satisfies a predetermined reference SD1. One of the operations is performed. Here, it is assumed that an enlargement instruction with an enlargement display magnification larger than a predetermined threshold value TH1 is given by the enlargement operation as the reference (condition) SD1.

  First, when the enlargement operation does not satisfy the predetermined reference SD1, a partial enlargement operation of the setting screen GA12 corresponding to the pinch-out operation is executed. Specifically, when the enlargement display magnification designated by the enlargement instruction by the enlargement operation does not exceed a predetermined threshold TH1 (for example, 130%), as shown in FIG. 5, the operation position in the pinchout operation is as shown in FIG. A part of the setting screen GA12 of FIG. 4 (display screen in the normal display mode MD1) GA12 is partially enlarged around the vicinity.

  On the other hand, when the enlargement operation satisfies the predetermined reference SD1, an automatic mode change from the normal display mode MD1 to the enlargement display mode MD2 is performed. Specifically, when the enlargement display magnification specified by the enlargement instruction by the enlargement operation exceeds a predetermined threshold value TH1, the display mode of the touch panel 25 is automatically changed from the normal display mode MD1 to the enlargement display mode MD2. Be changed. Note that the threshold value TH1 related to the enlarged display magnification is set in advance using a setting screen as shown in FIG. FIG. 8 shows a state in which the threshold value TH1 is set to “130%”.

  FIG. 6 is a diagram showing a display screen (setting screen) GA2 (GA22) in the enlarged display mode MD2. FIG. 6 shows a menu setting screen (color setting screen) GA22 for color setting in the enlarged display mode MD2.

  Similar to the color setting screen GA12 of FIG. 4, the color setting screen GA22 of FIG. 6 has five options (in detail) of “auto color”, “full color”, “black”, “two color”, and “single color”. Has buttons BD1 to BD5) respectively corresponding to the options. However, the color setting screen GA22 of FIG. 6 has a configuration different from the color setting screen GA12 of FIG. Specifically, the color setting screen GA12 has various buttons BN1 to BN7 for selecting setting items, whereas the color setting screen GA22 does not have these buttons BN1 to BN7. That is, the color setting screen GA22 has fewer buttons (options) than the color setting screen GA12. Each option on the color setting screen GA22 is displayed larger than each option on the color setting screen GA12. More specifically, the button area and the character of each option on the color setting screen GA22 (FIG. 6) in the enlarged display mode MD2 are the color setting screen GA12 (FIG. 4) in the standard state (non-enlarged state) of the normal display mode MD1, respectively. ) Is larger than the button area and character of each option. In the enlarged display mode MD2, relatively large characters and / or relatively large options are displayed, so that the operator can perform an operation on an easy-to-see setting screen.

  The enlarged display mode MD2 is a mode in which a screen having a configuration different from that of the normal display mode MD1 and a screen having a larger (relatively fewer) option than that in the normal display mode MD1 is displayed. Expressed.

  Note that display screens other than the display screen GA12 in the normal display mode MD1 (setting screens displayed in response to pressing of any of the setting item selection buttons BN1, BN3 to BN7) GA11, GA13 to GA17 (not shown) are displayed. In contrast, different display screens GA2 (GA21, GA23 to GA27) (not shown) in the enlarged display mode MD2 are prepared in advance. In the enlarged display mode MD2, the plurality of display screens GA2 (GA21 to GA27) and the like are appropriately displayed.

  When a pinch-in operation is performed in the enlarged display mode MD2, an operation opposite to the above is performed.

  FIG. 7 is a flowchart showing the above-described operation in the image forming apparatus 10. The operation shown in FIG. 7 is repeatedly performed at very short time intervals ΔT (for example, several tens of milliseconds).

  Here, it is assumed that the normal display mode MD1 is designated as the initial display mode, and the above-described display screen GA12 (FIG. 4) is first displayed on the touch panel 25 in the normal display mode MD1.

  Thereafter, when a user operation (in this case, a pinch-out operation or a pinch-in operation) is accepted by the input control unit 11 or the like in step S11, an update process to the display screen with an enlargement ratio designated by the operation is displayed in step S12. This is performed by the control unit 12 or the like.

  In step S13, branch processing according to the display mode of the touch panel 25 is executed. When the display mode is the normal display mode MD1, the process proceeds to step S14, and when the display mode is the enlarged display mode MD2, the process proceeds to step S16.

  Here, first, it is determined that display in the normal display mode MD1 is being performed, and the process proceeds to step S14.

  In step S14, it is determined whether or not the pinch operation in step S11 satisfies a predetermined reference SD1. When the pinch operation satisfies the predetermined reference SD1, specifically, when the enlargement display magnification designated by the pinch out operation in step S11 exceeds a predetermined threshold TH1 (for example, 130%), Proceed to step S15. If the pinch operation does not satisfy the predetermined standard SD1, the routine is temporarily terminated without proceeding to step S15.

  In step S15, an automatic mode change (switching) operation from the normal display mode MD1 to the enlarged display mode MD2 is executed. Specifically, the display control unit 12 and the mode control unit 15 replace the color setting screen GA12 in the normal display mode MD1 shown in FIG. 4 (or FIG. 5) with the color setting screen in the enlarged display mode MD2 shown in FIG. GA22 is displayed.

  In this manner, when the pinch-out operation received during display in the normal display mode MD1 satisfies the predetermined reference SD1, the display mode of the touch panel 25 is changed from the normal display mode MD1 to the enlarged display mode MD2. After that, menu screen transition is performed using a plurality of display screens prepared in advance for the enlarged display mode MD2.

  Conversely, when the pinch-in operation received during display in the enlarged display mode MD2 satisfies the predetermined reference SD2, the display mode of the touch panel 25 is changed from the enlarged display mode MD2 to the normal display mode MD1. Here, it is assumed that a reduction display instruction with a display magnification less than the display magnification corresponding to the reciprocal of the predetermined threshold TH1 is given by the reduction operation (pinch-in operation) as the reference (condition) SD2.

  Specifically, it is determined that display in the enlarged display mode MD2 is being performed, and the process proceeds from step S13 to step S16.

  In step S16, it is determined whether or not the pinch operation in step S11 satisfies a predetermined reference SD2. Specifically, when the pinch-in operation satisfies the predetermined standard SD2, the display magnification specified by the pinch-in operation is a threshold corresponding to the reciprocal of the predetermined threshold TH1 (for example, about 77% (= 100/130) If smaller, the process proceeds to step S17. If the pinch operation does not satisfy the predetermined reference SD2, the routine does not proceed to step S17, but the routine is temporarily terminated.

  In step S17, an automatic mode change operation from the enlarged display mode MD2 to the normal display mode MD1 is executed. Specifically, instead of the color setting screen GA22 in the enlarged display mode MD2 shown in FIG. 6, the color setting screen GA12 in the normal display mode MD1 shown in FIG. 4 is displayed.

  Thus, the automatic mode change operation from the enlarged display mode MD2 to the normal display mode MD1 is also performed.

  According to the above operation, when the enlargement operation (pinch-out operation) received during display in the normal display mode MD1 satisfies the predetermined reference SD1, the display mode of the touch panel 25 is enlarged from the normal display mode MD1. The mode is automatically changed to mode MD2 (steps S14 and S15). Therefore, it is possible to properly use the plurality of display modes MD1 and MD2. More specifically, the enlarged display mode MD2 can be used effectively (positively). In particular, a user who does not know the existence of the enlarged display mode can effectively (actively) use the relatively easy-to-see enlarged display mode MD2.

  Here, a technique different from the technique according to the above embodiment, specifically, a technique for enlarging each setting screen only by performing a pinch-out operation on each of a plurality of setting screens (also referred to as a technique according to a comparative example). Assumed). By using the technology according to the comparative example, a user who knows only the normal display mode MD1 can also enlarge and visually recognize each setting screen.

  However, performing a pinch-out operation on each of a plurality of setting screens (in other words, repeatedly performing a pinch-out operation every time a screen transition occurs) is complicated for the user. On the other hand, in the operation as in the above embodiment, since the automatic mode switching to the enlarged display mode MD2 is performed, such a complicated operation can be avoided.

  In the technology according to the comparative example, it is possible to adjust the portion to be watched to a desired size, but sometimes it is difficult to adjust the portion to be watched to a desired size. For example, it may be necessary to repeat the pinch out operation several times. Further, when performing screen enlargement with a pinch-out operation in the normal display mode MD1, what is a desired position (position to watch) contrary to the original intention of the operating user (depending on the skill of the operation). It may be enlarged around different positions. In such a case, the operating user is required to perform an operation for moving (sliding) the desired position into the display target area again. On the other hand, when the enlarged display mode MD2 is used as in the above-described embodiment, a display screen prepared in advance (designed in advance so as to be easy to see) is displayed on the touch panel 25 in consideration of ease of viewing. Therefore, it is not necessary to perform the enlargement operation and / or the slide movement operation again. The operating user can perform various operations while viewing an easy-to-see display screen (a large display screen) in the enlarged display mode MD2.

  In the above embodiment, the mode change from the normal display mode MD1 to the enlarged display mode MD2 is performed immediately after it is determined that the predetermined reference SD1 is satisfied (steps S14 and S15). However, it is not limited to this. For example, when it is determined that the predetermined standard SD1 is satisfied (step S14), before the display mode of the touch panel 25 is actually changed from the normal display mode MD1 to the enlarged display mode MD2 (step S15), The confirmation screen CF (CF1) in FIG. 9 may be displayed once. In the confirmation screen CF of FIG. 9, a character string “Do you want to switch from the normal display mode MD1 to the enlarged display mode MD2?” Is displayed. The confirmation screen CF is a screen for confirming that the display mode of the touch panel 25 is changed from the normal display mode MD1 to the enlarged display mode MD2. Then, the mode change operation to the enlarged display mode MD2 may be executed on the condition that the “Yes” button on the confirmation screen CF is pressed (change confirmation or change approval). Further, when the “No” button on the confirmation screen CF is pressed, the mode changing operation to the enlarged display mode MD2 may not be performed and the enlarged display in the normal display mode MD1 may be continued as it is.

  Similarly, a similar confirmation screen CF (also referred to as CF2) (not shown) may be temporarily displayed immediately before the automatic mode change operation in step S17. However, in the confirmation screen CF2, unlike the confirmation screen CF1 of FIG. 9, a reverse mode change operation (specifically, a switching operation from the enlarged display mode MD2 to the normal display mode MD1) is confirmed.

<2. Second Embodiment>
The second embodiment is a modification of the first embodiment.

  In 2nd Embodiment, the aspect which changes for every user whether the display mode automatic change operation is performed is illustrated.

  In the second embodiment, it is assumed that whether or not the display mode automatic change operation is executed is set for each user in advance (whether the automatic mode switching setting is enabled or disabled).

  FIG. 14 is a flowchart showing an operation according to the second embodiment.

  As can be seen from comparison with FIG. 7, in FIG. 14, step S21 is provided between step S14 and step S15. In step S21, it is determined whether or not a user who is set to execute the display mode automatic change operation (also expressed as an authorized user of the automatic change operation) is logged in. If the logged-in user is an authorized user for the automatic change operation, the process proceeds to step S15. That is, when a user who is set to execute the automatic change operation of the display mode is logged in, the display mode of the touch panel 25 is automatically changed from the normal display mode MD1 to the enlarged display mode MD2. On the other hand, when the logged-in user is not an authorized user for the automatic change operation (when a user who is set to not execute the display mode automatic change operation is logged in), the process does not proceed to step S15, and the display is performed. The mode automatic change operation (the operation of automatically changing the display mode of the touch panel 25 from the normal display mode MD1 to the enlarged display mode MD2) is not executed.

  In FIG. 14, step S22 is provided between step S16 and step S17. In step S <b> 22, it is determined whether or not the user who is set to execute the display mode automatic change operation (the user who is permitted to perform the automatic change operation) is logged in. If the logged-in user is an authorized user for the automatic change operation, the process proceeds to step S17. On the other hand, when the logged-in user is not an authorized user for the automatic change operation, the process does not proceed to step S17, and the display mode automatic change operation (the display mode of the touch panel 25 is automatically changed from the enlarged display mode MD2 to the normal display mode MD1). Is not executed.

  Also by such an aspect, it is possible to obtain the same effects as those of the first embodiment. In particular, the presence / absence of automatic mode change switching between the normal display mode MD1 and the enlarged display mode MD2 can be changed for each user. Therefore, it is possible to respect the user's intention. For example, a user who knows the existence of the enlarged display mode but does not want to use the enlarged display mode may set the automatic mode switching setting to invalid. In other words, the user may not set the user himself as an authorized user for the automatic change operation. According to this, the user can use the pinch-out operation exclusively as an operation for changing the enlargement magnification, and is automatically changed to the enlarged display mode according to the pinch-out operation against his / her own intention. Can be prevented.

<3. Third Embodiment>
The third embodiment is a modification of the first embodiment.

  In 3rd Embodiment, the aspect which changes whether the display mode automatic change operation is performed for every screen is illustrated.

  In the third embodiment, it is assumed that whether or not to execute the display mode automatic change operation is set in advance for each screen.

  FIG. 15 is a flowchart showing an operation according to the third embodiment.

  As can be seen from comparison with FIG. 7, in FIG. 15, step S23 is provided between step S14 and step S15. In step S23, it is determined whether the screen currently displayed on the touch panel 25 is a target screen for the mode automatic change operation. When the screen being displayed is the target screen for the mode automatic change operation, the process proceeds to step S15. That is, when a screen that is set to execute the automatic change operation of the display mode is displayed, the display mode of the touch panel 25 is automatically changed from the normal display mode MD1 to the enlarged display mode MD2. On the other hand, when the screen being displayed is not the target screen for the mode automatic change operation (when the screen set to not execute the display mode automatic change operation is displayed), the process does not proceed to step S15, The display mode automatic changing operation (the operation of automatically changing the display mode of the touch panel 25 from the normal display mode MD1 to the enlarged display mode MD2) is not executed.

  In FIG. 15, step S24 is provided between step S16 and step S17. In step S24, it is determined whether the currently displayed screen is a target screen for the automatic change operation. When the displayed screen is the target screen for the mode automatic change operation, the process proceeds to step S17. On the other hand, when the displayed screen is not the target screen for the mode automatic change operation, the process does not proceed to step S17, and the display mode automatic change operation (the display mode of the touch panel 25 is automatically changed from the enlarged display mode MD2 to the normal display mode MD1). The operation to change is not executed.

  Also by such an aspect, it is possible to obtain the same effects as those of the first embodiment. In particular, the presence / absence of automatic mode change switching between the normal display mode MD1 and the enlarged display mode MD2 can be changed for each screen. Therefore, it is possible to appropriately change whether or not to perform mode switching according to the contents of the screen.

  Examples of the screen set as the non-target screen for the automatic change operation include a preview display screen GC11 as shown in FIG. 16, a paper size setting screen GC12 as shown in FIG. For example, if the automatic mode conversion operation is not permitted on the preview display screen GC11 as shown in FIG. 16, the pinch-out operation can be exclusively used as a partial enlargement operation of the preview image PV in the preview display screen GC11. It is. Alternatively, on the paper size setting screen GC12 as shown in FIG. 17, the pinch-out operation can be used exclusively as a partial enlargement operation for the size designation areas (numeric display areas) DN1, DN2, etc.

<4. Fourth Embodiment>
In each of the above embodiments, a mode in which different display screens in the enlarged display mode MD2 are provided as transition destination screens for the plurality of display screens in the normal display mode MD1 is illustrated. In other words, a mode in which the display screen in the normal display mode MD1 and the display screen in the enlarged display mode MD2 are in one-to-one correspondence is illustrated. However, the present invention is not limited to this. For example, a plurality of display screens in the enlarged display mode MD2 may be provided as screens corresponding to a certain display screen in the normal display mode MD1. In short, the display screen in the normal display mode MD1 and the display screen in the enlarged display mode MD2 may correspond to 1 to N.

A total of 15 destinations DS1 to DS15 are displayed on the display screen GD1.

  On the other hand, FIG. 19 is a diagram showing the display screen GD2 in the enlarged display mode MD2. Here, regarding the display screen GD1 in the normal display mode MD1, three display screens GD2 (GD21, GD22, GD23) in the enlarged display mode MD2 are provided.

  More specifically, each of the display screens GD21, GD22, and GD23 is a screen that displays a relatively small number (specifically, a maximum of 6) of destinations. Specifically, the display screen GD21 displays six destinations DS1 to DS6, the display screen GD22 displays six destinations DS7 to DS12, and the display screen GD23 displays the remaining three destinations DS13 to DS15.

  In a case where a pinch-out operation is performed on the display screen GD1 in the normal display mode MD1, when a predetermined reference SD1 related to the pinch-out operation is satisfied, along with the mode transition from the normal display mode MD1 to the enlarged display mode MD2, Any one of the display screens GD21, GD22, and GD23 in the enlarged display mode MD2 is displayed instead of the display screen GD1.

  For example, when the vicinity of the destination DS2 on the display screen GD1 (FIG. 18) is enlarged by a pinch-out operation, the display screen GD21 is displayed instead of the display screen GD1 (see also the arrow AR11 in FIG. 20). When the vicinity of the destination DS9 of the display screen GD1 is enlarged by the pinch-out operation, the display screen GD22 is displayed instead of the display screen GD1. Similarly, when the vicinity of the destination DS15 of the display screen GD1 is enlarged by the pinch-out operation, the display screen GD23 is displayed instead of the display screen GD1. In the enlarged display mode MD2, a switching operation between the three display screens GD21 to GD23 is performed according to an operation of a hardware cursor key (arrow key) (not shown).

  The reverse mode change operation is performed in the same manner. Specifically, when the pinch-in operation is performed in a state where any one of the display screens GD21, GD22, and GD23 in the enlarged display mode MD2 is displayed and the predetermined standard SD2 related to the pinch-in operation is satisfied. Is displayed instead of the display screen GD1 in the normal display mode MD1 instead of the display screen GD2 in the enlarged display mode MD2 (see arrow AR12 in FIG. 20).

  Also by such an aspect, it is possible to obtain the same effects as those of the first embodiment. Here, the destination display screen is exemplified as the display screens GD1 and GD2, but the present invention is not limited to this, and other types of screens (such as a box display screen) may be used.

<5. Fifth Embodiment>
In the fourth embodiment, a mode in which a plurality of display screens in the enlarged display mode MD2 are provided as transition destination screens with respect to a certain display screen in the normal display mode MD1 is exemplified. However, the present invention is not limited to this. Not. For example, a common display screen in the enlarged display mode MD2 may be provided for a plurality of display screens in the normal display mode MD1. In short, the display screen in the normal display mode MD1 and the display screen in the enlarged display mode MD2 may correspond N-to-1.

  In the fifth embodiment, such an aspect will be described. More specifically, an automatic mode change to the enlarged display mode MD2 is performed according to a pinch-out operation on a plurality of display screens GA12, GA14 to GA17 (described later) in the normal display mode MD1, and the common display in the enlarged display mode MD2 is performed. A display screen GE2 (FIG. 21) is displayed.

  FIG. 21 is a diagram showing a display screen GE2 in the enlarged display mode MD2. The display screen GE2 is capable of accepting not only setting operations related to the setting item “color” but also setting operations related to other setting items “magnification”, “paper”, “double-sided / page aggregation”, and “finish”. It is a screen. Specifically, the buttons BE1, BE2, BE3, BE4, and BE5 provided for the setting items “color”, “magnification”, “paper”, “double-sided / page integration”, and “finish” are pressed. Thus, the setting contents of each setting item can be changed. For example, when the button BE1 in the setting item “color” is pressed, one of five options “auto color”, “full color”, “black”, “two color”, and “single color” is selected. The More specifically, each time the button BE1 in the setting item “color” is pressed, the next-ranked option (for example, “single color” next to “two-color”) is sequentially selected. Selected. Also, any of a plurality of options is selected in response to pressing of the button BE3 in the setting item “paper”. More specifically, each time the button BE3 in the setting item “paper” is pressed, the next-ranked option (for example, “A4” next to “automatic”) is sequentially selected. .

  This display screen GE2 is a common setting screen used when setting a plurality of setting items in the enlarged display mode MD2. The display screen GE2 in the enlarged display mode MD2 is a higher-level menu screen (or a consolidated menu screen) including not only the setting item (same level setting item) corresponding to the setting item “color” in the normal display mode MD1, but also other setting items. ).

  In the fifth embodiment, an automatic mode change to the enlarged display mode MD2 is performed in response to a pinch-out operation on the display screen GA12 (see FIG. 4) in the normal display mode MD1, and the common display in the enlarged display mode MD2 is performed. A screen GE2 (FIG. 21) is displayed.

  The same display screen GE2 is also displayed when the automatic mode change to the enlarged display mode MD2 is performed in response to a pinch-out operation on the setting screen GA14 (not shown) regarding other setting items in the normal display mode MD1. . Here, it is assumed that the setting screen GA14 is a detailed setting screen regarding a setting item “paper” different from the setting item “color”.

  Similarly, the same display screen GE2 is also displayed when the automatic mode change to the enlarged display mode MD2 is performed in response to a pinch-out operation on the display screens GA15, GA16, GA17 (not shown) in the normal display mode MD1. . Here, the display screens GA15, GA16, and GA17 are detailed setting screens relating to “magnification”, “double-sided / page aggregation”, and “finish”, respectively.

  Thus, the common display screen GE2 in the enlarged display mode MD2 may be displayed on the different display screens GA12, GA14 to GA17 in the normal display mode MD1. In other words, in response to a pinch-out operation in each of the display screens GA12 and GA14 to GA17 in the normal display mode MD1, the display screen in the enlarged display mode MD2 is not the same layer but a display screen in a higher layer (display at a relatively close level). Screen) may be automatically displayed.

  Similarly, an automatic mode change to the enlarged display mode MD2 is performed in response to a pinch-out operation on the plurality of display screens GA11 and GA13 in the normal display mode MD1, and the common display screen GE22 in the enlarged display mode MD2 is displayed. You may be made to do.

  Also by such an aspect, it is possible to obtain the same effects as those of the first embodiment. In particular, when a common display screen is used in the enlarged display mode MD2, it is possible to suppress the memory area for storing display image data, compared to the case where a plurality of different display screens are used in the enlarged display mode MD2. It is. That is, the memory area in the image forming apparatus can be effectively used. In such an image forming apparatus, it is possible to actively utilize the enlarged display mode by executing the automatic mode changing operation as described above.

<6. Sixth Embodiment>
In each of the embodiments described above, the mode in which the automatic mode change is performed from the normal display mode MD1 to the enlarged display mode MD2 according to the enlargement operation (pinch-out operation) is illustrated, but the present invention is not limited to this. For example, the automatic mode change may be performed from the reduced display mode MD0 to the normal display mode MD1 in accordance with an enlargement operation (pinch out operation). In the sixth embodiment, such an aspect will be described.

  The reduced display mode MD0 is a display mode for displaying a screen having a configuration different from that of the normal display mode MD1, and is a display mode for displaying a screen having more options than the normal display mode MD1. In the reduced display mode MD0, setting operations regarding a large number of setting items can be collectively performed on one screen. The reduced display mode MD0 is also expressed as a batch setting mode. The reduced display mode MD0 is also expressed as a mode for displaying a screen having options smaller than the options of the normal display mode MD1.

  FIG. 22 is a diagram showing a setting screen GD0 in the reduced display mode (batch setting mode) MD0. The setting screen GD0 in FIG. 22 collectively performs settings related to a relatively large number of setting items such as “color”, “density”, “paper”, “magnification”, “density”, and “duplex / page aggregation”. This is a possible screen. More specifically, on the setting screen GD0, a plurality of options are displayed for a plurality of setting items, respectively. The operator repeats an operation of selecting a desired option from a plurality of options for each setting item for a plurality of selection items in the setting screen GD0. Thereby, in the reduced display mode MD0, it is possible to perform setting operations regarding a plurality of selection items using a relatively small number (here, single) setting screen GD0.

  In the sixth embodiment, it is assumed that the display screen GD0 in the reduced display mode MD0 is displayed on the touch panel 25 in the initial state. The operator can perform an enlargement operation of the display screen GD0 by a pinch-out operation.

  When an enlargement operation that satisfies the predetermined standard SD1 is performed, an automatic mode change from the reduced display mode MD0 to the normal display mode MD1 is performed (see an arrow AR13 in FIG. 23). Specifically, when a pinch-out operation is performed in the reduced display mode MD0, if a predetermined standard SD1 related to the pinch-out operation is satisfied, the display screen GA1 (GA10) in the normal display mode MD1 (see FIG. 3). Is displayed instead of the display screen GD0 (FIG. 22) in the reduced display mode MD0. Thereafter, screen transitions related to various setting screens are performed in the normal display mode MD1.

  According to this, the operation screen of the normal display mode MD1 that is relatively easy to see is automatically displayed according to the enlargement operation that satisfies the standard SD1, and the operation using the operation screen can be easily performed. is there.

  Conversely, when a pinch-in operation is performed in the normal display mode MD1 and a predetermined reference SD2 related to the pinch-in operation is satisfied, the display screen GD0 (FIG. 22) in the reduced display mode MD0 is changed to the display screen GA1 (in the normal display mode MD1). GA10) is displayed (see also arrow AR14 in FIG. 23).

  According to the operation as described above, when the enlargement operation (pinch out operation) received during the display in the reduced display mode MD0 satisfies the predetermined reference SD1, the display mode of the touch panel 25 is changed from the reduced display mode MD0 to the normal display. The mode is automatically changed to mode MD1. Therefore, the plurality of display modes MD0 and MD1 can be properly used properly. More specifically, it is possible to automatically change from the mode MD0 having relatively options to the mode MD1 having relatively large options, and easily perform an operation using the relatively large options.

  Conversely, when the reduction operation (pinch-in operation) received during display in the normal display mode MD1 satisfies the predetermined reference SD2, the display mode of the touch panel 25 is automatically changed from the normal display mode MD1 to the reduction display mode MD0. Be changed. Therefore, the plurality of display modes MD0 and MD1 can be properly used properly. More specifically, the reduced display mode MD0 can be used effectively (positively). In particular, a user who does not know the existence of the reduced display mode MD0 can effectively (actively) use the reduced display mode MD0 that is useful for a batch designation operation of various settings.

<7. Modified example>
Although the embodiments of the present invention have been described above, the present invention is not limited to the contents described above.

  For example, in each of the above embodiments, the pinch-out operation on the touch panel 25 is exemplified as the enlargement operation by the operator, but is not limited thereto. For example, the enlargement operation by the operator may be performed by pressing a display magnification increase key (hardware key) (not shown) provided in the operation unit 6 of the image forming apparatus 10.

  Similarly, a pinch-in operation on the touch panel 25 is illustrated as a reduction operation by the operator, but is not limited thereto. For example, the reduction operation by the operator may be a pressing operation of a display magnification reduction key (hardware key) (not shown) provided in the operation unit 6.

  Further, in each of the above embodiments, whether to change the mode automatically (specifically, whether the reference SD1 is satisfied) may be determined according to the enlarged display magnification itself after the enlargement operation. Illustrated. More specifically, the case where the threshold value TH1 relating to whether or not to automatically change the mode is specified by the enlarged display magnification itself is illustrated. However, the present invention is not limited to this.

  For example, whether to change the mode automatically may be determined according to the display ratio of the operation keys (operation buttons) before and after the enlargement operation. More specifically, the threshold for automatic mode change (enlarged display magnification threshold) may be specified by the ratio between the key display area in the screen after the enlargement operation and the key display area in the reference screen. When a display instruction with a display magnification larger than the threshold is given, it is determined that the reference SD1 is satisfied, and a mode change operation from the normal display mode MD1 to the enlarged display mode MD2 is performed. Good.

  Alternatively, the threshold relating to automatic mode change (threshold for enlargement display magnification) is indicated by the ratio (for example, “80%”) between the number of keys displayed in the screen after the enlargement operation and the number of keys displayed in the reference screen. There may be. Then, on the condition that the key display number ratio is equal to or less than the threshold value, it is determined that an enlargement instruction (enlargement instruction of a certain degree or more) that satisfies the predetermined reference SD1 is given by the enlargement operation, and the normal display mode MD1 The mode change operation as described above from the display mode to the enlarged display mode MD2 may be performed. Hereinafter, a detailed description will be given with reference to FIG.

  In FIG. 11, a screen (reference screen) GB11 before the enlargement operation is shown. On the screen GB11, 11 operation keys (operation buttons) BC1 to BC11 are displayed. It is assumed that a broken line area (area surrounded by a broken line) DR of the screen GB11 is enlarged and displayed on the entire touch panel 25 as a screen GB12 after the enlargement operation by the enlargement operation (pinch out operation). Six operation keys BC1 to BC6 are displayed on the screen GB12 after the enlargement operation.

  As shown in FIG. 11, when the number of key displays in the screen (reference screen) GB11 before the enlargement operation is 11 and the number of key displays in the screen GB12 after the enlargement operation is 6, enlargement is performed. The key display number ratio before and after the operation is about 55% (= 6/11), which is smaller than the threshold “80%”. In other words, a smaller number of keys than the display state corresponding to the threshold value are displayed on the entire screen, and the substantial enlarged display magnification after the enlargement operation is a threshold value related to the key display number ratio (“80%”). Is larger than the enlargement magnification corresponding to. In this case, it is determined that an enlargement instruction with an enlargement display magnification larger than a predetermined threshold is given by the enlargement operation, and the above-described automatic mode change from the normal display mode MD1 to the enlargement display mode MD2 is performed. May be. Note that the threshold (“80%”, etc.) regarding the key display number ratio before and after the enlargement operation may be set in advance on a setting screen as shown in FIG. 10, for example.

  Moreover, in each said embodiment, the mode automatic change is illustrated when the reference | standard that the enlargement instruction | indication of the enlarged display magnification larger than a predetermined threshold is given by enlargement operation is satisfy | filled. In other words, there is exemplified an aspect in which it is determined whether or not the mode automatic change is performed based on the index value regarding the enlarged display magnification. However, the present invention is not limited to this.

  For example, when the standard SD1 that the enlargement instruction more than the predetermined threshold TH2 is given by the enlargement operation is satisfied, the mode automatic change from the normal display mode MD1 to the enlargement display mode MD2 is performed as described above. You may be made to be.

  More specifically, on the condition that the number of enlargement instructions is equal to or greater than the threshold value TH2, it is determined that an enlargement instruction satisfying a predetermined reference SD1 (an enlargement instruction of a certain degree or more) is given by an enlargement operation, The mode automatic change as described above may be performed from the display mode MD1 to the enlarged display mode MD2. Note that the threshold value regarding the number of enlargement instructions (such as “5 times”) may be set in advance on a setting screen as shown in FIG. 12, for example.

  Further, the number of enlargement instructions may be accumulated without depending on the logged-in user, but may be accumulated for each logged-in user. Alternatively, the number of enlargement instructions may be accumulated without depending on the screen, but may be accumulated for each screen.

  Alternatively, when the criterion that the enlargement instruction on the number of types of screens larger than the predetermined threshold is given by the enlargement operation is satisfied, the mode automatic change from the normal display mode MD1 to the enlargement display mode MD2 as described above is performed. It may be performed.

  More specifically, on the condition that the number of screen types to which an enlargement instruction is given is greater than or equal to the threshold value TH3, an enlargement instruction that satisfies a predetermined criterion (a certain degree or more enlargement instruction) is given by the enlargement operation It may be determined and the mode automatic change as described above from the normal display mode MD1 to the enlarged display mode MD2 may be performed. Note that the number of times of the screen type may be accumulated regardless of the user, or may be accumulated for each logged-in user.

  Further, it may be determined that the predetermined reference SD1 is satisfied on the condition that the slide movement amount immediately after the enlargement operation is equal to or greater than a predetermined threshold. In the normal display mode MD1, when the operator performs a pinch-out operation, if a portion greatly deviated from a desired position is enlarged, an operation of sliding relatively large immediately after the pinch-out operation (by a flick operation or the like) In many cases, it is further accompanied by a movement operation in the vertical and horizontal directions. When such a relatively large slide movement operation is involved, there is a high possibility that the operator feels troublesome. Therefore, when a relatively large slide movement operation (a slide operation larger than a threshold value (e.g., equivalent to 200 pixels)) is performed immediately after the pinch-out operation, the normal display mode MD1 is changed to the enlarged display mode MD2 as described above. The automatic mode changing operation may be performed. Note that the threshold (“200” pixels or the like) relating to the slide movement operation may be set in advance on a setting screen as shown in FIG. 13, for example.

  It should be noted that various modifications similar to those described above can be made with respect to the reference SD2.
