Description

  The present invention relates to an image forming apparatus having a plurality of functions and performing an image forming process using these functions.

  Recent image forming apparatuses have many functions. Examples of functions that the image forming apparatus has include a zoom copy function that performs reduced copy and enlarged copy, and a double-sided copy function that performs image forming processing on both sides of a sheet. With such a function, the user can copy the document to a desired state.

  However, as the functions of the image forming apparatus increase, more functions cannot be set in combination depending on the contents and types of the functions. In view of this, there has been proposed an image forming apparatus that can prevent the setting of a plurality of functions that cannot be combined with each other (Patent Documents 1 to 4).

Specifically, as such a technique, priority is given to one of a plurality of functions that cannot be combined with each other to cancel the setting of other functions, or the liquid crystal display unit notifies the user of the cancellation. Have been proposed.
Japanese Patent Laid-Open No. 2-199475 (published on August 7, 1990) JP-A-9-179450 (released July 11, 1997) Japanese Patent Laid-Open No. 11-168318 (published on June 22, 1999) JP 2003-11471 A (published January 15, 2003)

  However, in the conventional image forming apparatus, it cannot be said that the user can sufficiently recognize the combination of functions that cannot be set. If an input operation to the image forming apparatus is performed in a state where the user does not fully recognize the combination, the setting of the function that the user wants to prioritize may be canceled. If the image forming apparatus executes processing such as printing without the user noticing that the setting has been cancelled, the finished printed matter will be different from the user's desire. Also, even if the user notices that the setting has been canceled, the user must perform an operation for resetting the function.

  SUMMARY An advantage of some aspects of the invention is that it provides an image forming apparatus that allows a user to easily recognize which functions cannot be combined with each other.

  In order to solve the above problems, an invention according to claim 1 is an image forming apparatus having a plurality of functions, wherein a display unit displays a plurality of keys respectively corresponding to the plurality of functions, and the key is pressed. Accordingly, whether or not a specification unit for specifying a function to be used from the plurality of functions, a function specified by the specification unit, and a function other than the specified function among the plurality of functions can be combined. A determination unit for determining, a key corresponding to the specified function, and at least one key corresponding to a function that cannot be combined with the specified function are indicated by the same predetermined color different from the background. A display control unit for controlling the display unit.

  In particular, by controlling the display control unit, the key corresponding to the designated function and at least one of the keys corresponding to the function that cannot be combined with the designated function are indicated by a color different from the background. The image forming apparatus can make the user easily recognize these keys.

  Further, the image forming apparatus indicates the keys corresponding to the designated function and at least one of the keys corresponding to the functions that cannot be combined with the designated function with the same color. The user can easily recognize that the corresponding functions cannot be combined with each other.

  According to a second aspect of the present invention, in the image forming apparatus of the first aspect, the plurality of keys are displayed separately on a plurality of screens, and a tab that is displayed simultaneously is attached to each of the plurality of screens. The display control unit can control the display unit so that the tab attached to the screen including the key indicated by the predetermined color among the tabs is indicated by the predetermined color. It is preferable that

  In the image forming apparatus, a tab attached to a screen including the above key is also displayed in a predetermined color so that the user can easily recognize which screen has a key corresponding to a function that cannot be specified. it can.

  In addition, when the user presses a plurality of keys, it can be set as appropriate as to which function the designation unit designates.

  For example, as described in claim 3, in the image forming apparatus according to claim 1 or 2, once the designation unit designates one function in response to pressing of one key, it is combined with the one function. The designation of the one function may be maintained even when another key corresponding to the function that is not present is further pressed.

  According to a fourth aspect of the present invention, in the image forming apparatus of the third aspect, the designation unit once designates one function in response to pressing of one key and is not combined with the one function. When another key corresponding to a function is continuously pressed for a predetermined time or more or a predetermined number of times, the specification of the one function can be canceled and a function corresponding to the other key can be newly specified. It may be like this.

  This image forming apparatus can cancel the designation once for one function and re-designate another function as desired by the user. Therefore, it is more convenient for the user.

  Further, according to a fifth aspect of the present invention, in the image forming apparatus according to the third or fourth aspect, the display control unit includes a key corresponding to a function once designated by the designation unit, and the one key. The display unit may be controlled so that keys corresponding to all functions that cannot be combined with the functions are indicated by the same predetermined color.

  Furthermore, as described in claim 6, in the image forming apparatus according to claim 3 or 4, the display control unit includes one key corresponding to one function once designated by the designation unit, and the one key. The display unit may be controlled so that the pressed key among the keys corresponding to the functions that cannot be combined with the functions is indicated by the same predetermined color.

  According to a seventh aspect of the present invention, in the image forming apparatus of the first or second aspect, the designation unit temporarily designates one function in response to pressing of one key, and then combines with the one function. When another key corresponding to a function that cannot be performed is pressed, the designation of the one function may be canceled and a function corresponding to the other key may be newly designated.

  Furthermore, as described in claim 8, in the image forming apparatus according to claim 7, the display control unit includes one key corresponding to one function that is once designated by the designation unit and then deselected. The display unit can be controlled so that another key corresponding to another function newly designated by the designation unit instead of the one function is indicated by the same predetermined color. May be.

  According to the image forming apparatus of the present invention, the display control unit controls the key corresponding to the designated function and at least one of the keys corresponding to the function not combined with the designated function in a color different from the background. The image forming apparatus can make the user easily recognize these keys.

  In addition, the image forming apparatus indicates the keys corresponding to the designated function and at least one of the keys corresponding to the functions not combined with the designated function by using the same color. The user can easily recognize that the functions corresponding to are not combined with each other.

As illustrated in FIG. 4, the combination information table 51 d indicates whether a combination between the functions installed in the image forming apparatus 1 is possible or not. In FIG. 4, those that can be combined are indicated by “◯”, and those that cannot be combined are indicated by “X”. For example, the combination information table 51d in FIG. 4 indicates that the aggregation function and the pagination function for assigning page numbers to sheets can be combined, and the aggregation function and the image composition function cannot be combined. It is shown that.

(3) Function Setting Hereinafter, the operation of the image forming apparatus 1 in setting the function will be described.

(3-1) Initial Setting FIG. 5 is a flowchart showing processing of the image forming apparatus 1 at the time of initial setting. FIGS. 6 to 8 show specific examples of screens displayed on the touch panel 5a during this processing operation. FIG.

  When the user presses an initial setting key (not shown) in the operation key group 5b, the following operation is started.

  First, the control unit 44 displays the password acceptance screen P1 on the touch panel 5a (S1). Is displayed. As shown in FIG. 6, the password acceptance screen P1 displays a message prompting the current input person to input a password, such as “Please enter the management password”, and the input character string is in plain characters. Is displayed. If the character string input via the password acceptance screen P1 matches the password, the control unit 44 displays the selection screen P2 on the touch panel 5a (Yes in S2 → S3). If they do not match, the process returns to the above-described step S1 again (No in step S2 → S1).

  The selection screen P2 is a screen for allowing the user to select which function of the various functions to change the initial setting value. The selection screen P2 includes a plurality of keys as shown in FIG. 7, and particularly includes a priority mode setting key K21. When the priority mode setting key K21 is pressed by the user, the control unit 44 displays the priority mode setting screen P3 on the touch panel 5a (Yes in S4 → S5). On the other hand, when another key of the selection screen P2 is pressed, the control unit 44 changes each initial setting value according to the pressed key (No in S4 → S10).

  As shown in FIG. 8, the priority mode setting screen P3 includes a first priority mode key K31, a rear priority mode key K32, an automatic mode key K33, and the like. The control unit 44 selects one of these three priority modes according to the key pressed by the user (S6 to S9). Details of these three modes will be described later.

(3-2) Function Specification Next, function specification will be described with reference to FIGS. FIG. 9 is a flowchart showing the processing operation of the image forming apparatus 1 when a function is designated, FIG. 10 is a flowchart showing details of the processing operation when the function is designated in the first priority mode, and FIG. 11 is a function designation in the post-priority mode. 12 is a flowchart showing details of the processing operation at the time, FIG. 12 is a flowchart showing details of the processing operation when the function is specified in the automatic priority mode, and FIG. 13 is an example of a screen displayed on the touch panel 5a in the processing of FIG. 14 to 17 are examples of screens displayed by the process of FIG. 10, and FIG. 18 is an example of the screen displayed by the processes of FIG. 10 or FIG. Is an example of a screen displayed in the flow of FIG.

  This operation is realized by the CPU 53 functioning as a determination unit, a designation unit, and a display control unit to control each unit in the image forming apparatus 1. The CPU 53 functions as a determination unit, a designation unit, and a display control unit by executing the combination determination program 51a, the operation panel control program 51b, and the image formation control program 51c.

  In the following, the function designation will be described by taking as an example a copy execution in particular. However, when the image forming apparatus 1 functions as a printer, a facsimile, a scanner, or the like in addition to copying, the function designation is performed by the same processing. It can be carried out.

  When the copy is possible, the control unit 44 displays the standby screen P4 on the touch panel 5a. The standby screen P4 includes tabs T1 to T5 and a setting screen corresponding to each tab. Tabs T1 to T5 correspond to five setting screens of “simple setting”, “document / paper / finishing”, “image quality”, “layout / editing”, and “application / others”, respectively. When any one of the tabs is pressed, the touch panel 5a displays a setting screen corresponding to the pressed tab. In addition, on each setting screen, function selection keys respectively corresponding to the functions listed in the combination information table 51d shown in FIG. 4 are displayed.

  FIG. 13 shows a standby screen P4 when the tab T2 is pressed. On the standby screen P4, the “original / paper / finish” setting screen P41 is opened. This “original / paper / finish” setting screen P41 includes function selection keys (K41 to K44) corresponding to the functions of paper selection, mixed document size loading, punching, and stapling, respectively. Different function selection keys are provided on the screens corresponding to the other tabs (T1, T3 to T5). Each tab (T1 to T5), the background G1 of the setting screen corresponding to each tab, the function selection key, and the like are usually represented in monochrome.

  When the function selection key is pressed (Yes in S12), the control unit 44 performs function designation according to a priority mode corresponding to the user stored in the HDD 45 (S13 to S14, A to C). Function designation means designation of a function used in the current job in response to pressing of a function selection key. The control unit 44 can also control the touch panel 5a so that the function selection key and the tabs T1 to T5 are indicated by a predetermined color in response to pressing of the function selection key.

  When the start key included in the operation key group 5b is pressed, the job is executed using the function designated at that time (Yes in S11 of FIG. 9).

  Here, the first priority mode, the second priority mode, and the automatic priority mode will be briefly described. The first priority mode is a mode in which the function corresponding to the previously pressed function selection key is designated with higher priority than the function corresponding to the later pressed function selection key. The post-priority mode is a mode that preferentially designates the function corresponding to the function selection key pressed later, contrary to the pre-priority mode, and the automatic priority mode is prioritized according to various operating conditions. The function to be specified is preset by the designer (manufacturer) and the function is specified according to this setting. In the following, function designation by these priority modes will be described in more detail.

(3-2-a) Destination priority mode When the prioritization mode is selected in the initial setting described above, step S13 is Yes in the flowchart of FIG. 9, and the control unit 44 performs control according to the flow of FIG. Do.

  First, the control unit 44 determines whether another function has already been designated when the function selection key is pressed (S21). If no other function is specified, the function corresponding to the function selection key pressed in step S12 is specified as the function used in the current job (No in S21 to S23). Then, the function selection key of the designated function is displayed in a predetermined color (S24).

  By displaying the function selection key of the function designated in this way in a predetermined color, the image forming apparatus 1 has an effect that the user can easily recognize which function is designated.

  The “predetermined color” is not limited to a specific color as long as the above effect can be realized. In this embodiment, since the background G1 and the function selection key are normally displayed in monochrome, colors other than white and black (including gray) can be used as “predetermined colors”. That is, in the present embodiment, a phrase such as “display with a predetermined color” or “add a predetermined color” means “perform color display”.

  After step S24, the control unit 44 further determines whether there is a function that cannot be combined with the designated function (S25).

  If there is a function that cannot be combined (Yes in S25), the function selection key of the function that cannot be combined is grayed out under the control of the control unit 44 (S26). The predetermined color used in step S24 is given to the surroundings (S27). Further, among the tabs T1 to T5, the predetermined color is also given to the tab corresponding to the setting screen including the function selection key displayed in gray out or in color (S28).

  On the other hand, if the designated function can be combined with any of the functions (No in S25), the processes in steps S26 to S28 are not performed, and no color is given except for the function selection key of the designated function.

  When the above process is completed, the control unit 44 returns to the determination in step S11 again (No in S25 or S28 → D → S11).

  By the way, when it becomes Yes at Step S21, that is, when another function has already been designated, the control unit 44 refers to the combination information table 51d and corresponds to the function selection key pressed at Step S12. And whether or not the already specified function can be combined (S22).

  If it is determined in step S22 that they can be combined (Yes in S22), the control unit 44 designates the function corresponding to the function selection key pressed in step S12 as the function used in the current job (S23). . The function selection key of the designated function is given a predetermined color as described above (S24). However, at this time, this function selection key is given a color different from that of the function selection key of the function already specified. That is, when a plurality of functions that can be combined with each other are designated, the function selection keys corresponding to these functions are given different colors.

  On the other hand, if it is determined in step S22 that combination is not possible (No in S22), the control unit 44 does not designate the function corresponding to the function selection key pressed in step S12, and maintains the designation that has already been made ( No → D in S29).

  However, if a predetermined designation canceling operation is performed (Yes in S29), the control unit 44 cancels the designation for the already designated function, and performs a function corresponding to the function selection key pressed in step S12. A new designation is made (S30 → S23). The processing after step S23 is as already described. In this embodiment, it is assumed that the designation canceling operation is a long key press.

  As described above, since the function selection key of the designated function and the surroundings of the function selection key of the function that cannot be combined therewith are displayed in color, these function selection keys are emphasized, so that the image forming apparatus of the present embodiment 1 allows the user to easily recognize which function cannot be specified.

  Furthermore, by displaying the function selection key of the designated function and the surroundings of the function selection key of the function that cannot be combined with the same color, the image forming apparatus 1 according to the present embodiment also allows combinations of functions that cannot be designated by the user. Can be easily recognized.

  Further, the image forming apparatus 1 according to the present exemplary embodiment is configured such that the same color as the function selection key is attached to the tab of the screen including the function selection key of the designated function or the function selection key of the function that cannot be combined therewith. The user can easily recognize on which screen these function selection keys exist.

  Here, give a more specific example. This embodiment will be described.

  Assume that the punch key K43 is pressed when the function has not yet been specified, that is, when the “original / paper / finishing” setting screen P41 is displayed as shown in FIG. 13 (Yes in S12 and S13, and in S21) No). Then, the punch function is designated and the punch key K43 is displayed in green (S23 → S24). As shown in FIG. 4, the punch function and the staple function cannot be combined (Yes in S25). Therefore, the staple key K44 is grayed out and the surrounding area R1 is displayed in the same green as the punch key K43 (S26 → S27). Further, since the tab T2 corresponding to the “original / paper / finishing” setting screen P41 is also displayed in green, the “original / paper / finishing” setting screen P41 is displayed as shown in FIG.

  If the paper selection key K41 is further pressed from the state shown in FIG. 14, since there is no function that cannot be combined with the paper selection function, only the paper selection key K41 is added with blue to designate the paper selection function. (No in S25, FIG. 15).

  Further, for example, it is assumed that the document size mixed loading key K42 is pressed in a state where the punch function is selected (FIG. 14) (Yes in S21). As shown in FIG. 4, the document size mixed loading function can be combined with the punch function, but aggregation, frame erasing, image composition, and booklet cannot be combined with each other (Yes in S22,..., S25). Yes). At this time, as shown in FIG. 16, the control unit 44 adds a yellow display of the original size mixed key K42, and controls the touch panel 5a to add yellow in addition to the green already attached to the tab T2. In particular, in this embodiment, the tab T2 is divided into upper and lower parts, and yellow and green are given to the respective areas generated by the division.

  Here, the aggregation key K51 and the booklet key K54 respectively corresponding to the aggregation function and the booklet function are displayed on the “layout / edit” setting screen P42 corresponding to the tab T4 (FIG. 17). Further, a frame erase key and an image composition key respectively corresponding to the frame erase function and the image composition function are provided on the “application / others” setting screen corresponding to the tab T5 (not shown). Therefore, under the control of the control unit 44, yellow is added to the periphery R2 of the collective key K51 and the periphery R3 of the booklet key K54 as shown in FIG. 17, and also to the periphery of the frame erase key and the image composition key (not shown). Similarly yellow. The tab T4 and the tab T5 are also yellow.

  Further, for example, assume that the staple function K44 is pressed for a long time when the punch function is designated and the display state shown in FIG. Then, the staple function is designated and the designation of the punch function is canceled (No in S22 → Yes in S29 → S30). Then, the staple key K44 and the periphery R4 of the punch key K43 are displayed in green (FIG. 18). At this time, the punch key K43 itself is returned to monochrome and displayed in gray out.

(3-2-b) Post-priority mode When the post-priority mode is selected in the initial setting described above, step S14 is Yes in the flowchart of FIG. 9, and the control unit 44 performs control according to the flow of FIG.

  Similar to the first priority mode in the column (3-2-a), when the function selection key is pressed in step S12, the control unit 44 first determines whether there is a function that has already been specified (S31). ).

  If the function has not yet been specified (No in S31), the function corresponding to the function selection key pressed in step S12 is specified (S33). Then, a function selection key corresponding to the designated function is displayed in a predetermined color (S34). When all the above processes are completed, the process flow returns to step S11 (D → S11).

  On the other hand, if the function has already been specified (Yes in S31), the control unit 44 determines whether the function corresponding to the pressed function selection key can be combined with the already specified function ( S32).

  If possible, the processing after step S33 described above is executed (Yes in S32 → S33 → S34 → D).

  If not possible, the function already specified is canceled (No in S32 to S35), and the function corresponding to the function selection key pressed in Step S12 is specified as the function to be used (S36). Then, the function selection key of the function whose designation is canceled in step S36 is grayed out (S37). Then, the function selection key for the designated function, that is, the function selection key pressed in S12, the function selection key for the function for which the designation is canceled in step S35, and a setting screen including any one of these function selection keys Are displayed in a predetermined color (S38 → D).

  In this embodiment, the “predetermined color” in step S38 is the same as the color assigned to the function selection key of the function whose designation is canceled in step S35.

  For example, it is assumed that the punch key K43 is pressed in a state where the post-priority mode is set and the function is not yet specified (the state in FIG. 13) (Yes in S12 → No in S13 → Yes in S14 → No in S31). . In this case, the punch function is designated (S33), and only the punch key K43 is displayed in green as shown in FIG. 19 (S34).

  Thereafter, when the staple key K44 is pressed (Yes in S31 → No in S32), the designation of the punch function is canceled and the staple function is designated (S35 → S36). Then, as shown in FIG. 18, the punch key K43 is displayed in monochrome grayout (S37), and the staple key K44 and the periphery of the punch key K43 are displayed in green (S38). At this time, the tab T2 is also colored green.

  In step S37, since the area around the function selection key “of the function whose designation has been canceled” is displayed in color, the area around the function selection key of the function that has not been specified is not displayed in color.

  For example, when the staple key K44 is pressed after the punch key K43 and the booklet key K54 is pressed after the aggregation key K51, the periphery R4 of the punch key K43, the staple key K44, and the tab T2 are displayed in green. A yellow display of the periphery R2 of the aggregation key K51, the booklet key K54, and the tab T4 is added to the screen P4. 20, the “layout / edit” setting screen P42 is shown in FIG.20, and the illustration of the original / paper / finishing setting screen P41 is omitted. The yellow key is displayed around the function selection keys of functions that have not been specified, such as the mixed loading key K42 and the tabs T2 and T3, but which cannot be combined with the booklet functions, and the tabs attached to the screens including these function selection keys. Is not attached.

  On the other hand, it is assumed that the staple key K44 is pressed after the punch key K43, the booklet key K54 is pressed after the aggregation key K51, and the original size mixed key K42 is pressed after that. In this case, the periphery R4 of the punch key K43, the staple key K44, and the tab T2 are displayed in green, and the original size mixed key K42, the periphery R2 of the aggregation key K51, the periphery R3 of the booklet key K54, and the yellow of the tab T4 are displayed. Added to screen P4. The lower half of the tab T2 is maintained in green, and the upper half is displayed in yellow (FIGS. 21 and 22).

(3-2-c) Automatic priority mode When the automatic priority mode is selected in the initial setting described above, the control unit 44 performs control according to the flow of FIG.

In this mode, when a function is designated (S43), the function selection key for the designated function is displayed in a predetermined color (S44), as in the other modes. In this mode, in particular, the function selection key that cannot be combined with the designated function and has a lower priority is grayed out (Yes in S45 → S46), and the function selection displayed in grayout is selected. The area around the key is displayed in a predetermined color (S47). As in the other modes, the predetermined color is added to the tab of the screen including the function selection key displayed in gray out in this way or the function selection key displayed in color in step S44 (S48).
If the function corresponding to the pressed function selection key should be prioritized over the already designated function (No in S42 → Yes in S49), the already designated function is canceled (S50), and step The process after S43 is performed. On the other hand, if the function corresponding to the pressed function selection key should not be given priority over the already specified function, the already specified designation is maintained (No in SS49).

  For example, assume that the punch key K43 and the staple key K44 are pressed in this order in this mode.

  When the staple function should be given priority over the priority of the punch function, the punch function is once designated, and the punch key K43 is displayed in green as in FIG. 19 (No in S43 → S44 → S45). . Then, when the staple key K44 is pressed, the designation of the punch function is canceled and the staple function is designated (No in S42 → Yes in S49 → S50 → S43). Further, by the processing after step S44, as shown in FIG. 18, the staple key K44, the periphery R4 of the punch key K43, and the tab T2 are displayed in green (Yes in S44 → S45 → S46 to S48).

  On the other hand, if the priority of the punch function is set higher than the priority of the staple function, first, the punch function is designated by pressing the punch key K43 (S43). Similarly to FIG. 14, the punch key K43, the periphery R1 of the staple key K44, and the tab T2 are displayed in green (Yes in S44 → S45 → S46 to S48). Next, even if the staple key K44 is pressed, the designation of the punch function and the display of FIG. 14 are maintained.

(4) Other forms of first priority mode The control unit 44 may perform processing described below instead of the processing described in the section (3-2-a). Processes not specifically mentioned below are as described above.

  FIG. 23 is a flowchart of function setting in the first priority mode in this embodiment, and FIGS. 24 to 28 are examples of screens displayed on the touch panel 5a in the flow of FIG.

  In this embodiment, even if a single function is simply designated, even if there is a function that cannot be combined with this one function, color display is not performed and the function specified in step S103 cannot be combined. Only the function selection key for the function is grayed out (No in S101 or Yes in S102 → S103 → S104 → S105 → D).

  On the other hand, when a function has already been designated (Yes in S101) and a function selection key for a function that cannot be combined with the designated function is pressed (No in S102), the function selection key for the designated function is not selected. A predetermined color is given to the surroundings, the surroundings of the function selection key newly pressed in step S12, and the tab attached to the setting screen including any of these function selection keys (S106). When the newly pressed function selection key is pressed for a long time (Yes in S107), the designation of the already designated function is canceled (S108), and the color display around the function selection key is changed to the background G1. The color is returned to the same color, and the tab color is also returned to the original monochrome display (S109). If the function selection key is not pressed for a long time, the specified designation is maintained (No → D in S107).

  According to this mode, for example, when the punch key K43 is pressed in the state of FIG. 13, the punch function is designated, and the staple key K44 is grayed out as shown in FIG. 24 (No → S103 → S104 → S105 in S101). → D). When the staple key K34 is further pressed, the periphery R4 of the punch key K33 and the periphery R1 of the staple key K34 are displayed in green (Yes in S101 → No in S102 → S106, FIG. 25).

  Assume that the document size mixed key K42 and the collect key K51 are further pressed in this order from the state shown in FIG. At this time, as shown in FIGS. 26 and 27, the aggregation key K51 and the booklet key K54 are grayed out by the above-described processing, and the periphery R2 of the aggregation key K51, the periphery R5 of the document size mixed key K42, and the tab T2 are displayed. Half and tab T4 are displayed in yellow.

  Thereafter, when the staple key K44 is pressed for a long time (Yes in S107), the designation of the punch function is canceled (S108), and the staple function is designated (S103). As shown in FIG. 28, the colors around the punch key K43 and the staple key K44 are returned to the original background color (S109), and yellow is removed from the tab T2 and only green is added.

(5) Color display mode The display of the function selection keys and tabs in the present invention is not limited to the display described in the above-mentioned columns (3) and (4). That is, the image forming apparatus 1 only needs to realize the above-described effect that the user can easily recognize an impossible combination, and the display form on the touch panel 5a can be changed as appropriate within a range in which this effect can be realized. is there.

  In the following (5-1) column, referring to FIG. 29, the display mode of the function selection key and the like will be described, and in the following (5-2) column, other display modes of the tab will be described with reference to FIG. .

(5-1) Display Mode of Function Selection Key The above-described staple key K44 in FIG. 14 is surrounded by a colored region (color region).

  However, the function selection key does not have to be completely surrounded by the color area. For example, as shown in FIG. 29 (a-1) or (a-2), the color area is provided only to the right or below the function selection key, and is not surrounded by the color area around the function selection key. An area may exist. Further, a part of one function selection key itself may be colored (FIG. 29 (a-3)).

  In addition, the color area is a blinking display in which a colored state (FIG. 29 (a-4)) and a grayed state (FIG. 29 (a-5)) are alternately displayed. May be.

  Further, not only the display form of the function selection key of the function that cannot be combined but also one of FIGS. 29A-1 to 29A-5 is selected as the display form of the function selection key of the designated function. A display form is also included in the embodiment of the present invention. For example, on the screen shown in FIG. 14, the display of the punch key K43 may be in the form of FIG. 29 (a-3), and the display of the staple key K44 may be in the form of FIG. 29 (a-2).

  Further, even when an icon representing the function is displayed near the function selection key, the display mode described above can be applied. At this time, the entire area including the function selection key and its icon can be replaced with the function selection key in the display mode described above. That is, for example, the entire area may be colored (FIG. 29 (b-1)), or the area may be colored (FIG. 29 (b-2)).

  In the above-described FIG. 14 and the like, a function selection key of a designated function and a function selection key of a function that cannot be combined therewith, one is colored on the key itself and the other is colored around the key. The display forms are different from each other. This makes it easy for the user to identify these functions from each other.

  However, the present invention is not limited to this, and the function selection key for the designated function and the function selection key for the function that cannot be combined therewith may have the same display form. That is, both of these function selection keys can be colored like the punch key K43 in FIG. 14, and conversely, both can be similarly colored. More specifically, the display forms of both of these function selection keys may be the same display form of any of the display forms shown in each drawing of FIG.

  As described above, adding a color to the function selection key itself or adding a color around the function selection key can be collectively expressed as “indicated by color”. That is, as shown in each drawing of FIG. 29, even if the region to which the color is attached is different, if the attached color is the same, it is included in what is indicated by the same color.

  The “same color” here includes not only completely the same color but also substantially the same color. When a user who sees a function selection key with one color and a function selection key with another color can recognize that these function selection keys are related to each other, It can be said that the color and the other colors are substantially the same color.

  Moreover, the color used for the display described above may be determined by the function, and the priority of the color may be determined in advance. In the former case, the color used for each function is always the same, for example, the original size mixed key K42 is indicated in yellow and the punch key K43 is indicated in green, for example. In the latter case, it is predetermined that, for example, green and yellow are used in this order. That is, when the original size mixed key K42 and the punch key K43 are colored in this order, the original mixed key K42 is colored green and the punch key K43 is colored yellow. If the order in which colors are added is reversed, the colors to be added are also reversed.

(5-2) Tab Display Form As shown in FIGS. 21 and 26, when a plurality of function selection keys indicated by different colors are displayed on one screen with one tab attached, The above-mentioned one tab is given these different colors. At this time, in FIG. 21 and FIG. 26 and the like, the tab T2 is divided into two upper and lower areas, and the same color as that assigned to the plurality of function selection keys is assigned to each of the divided areas. FIG. 30A shows the tab T having such a display form in an enlarged manner. On the tab T, regions I and II to which different colors are attached are provided.

  However, the present invention is not limited to this, and as long as one or more colors are appropriately attached on one tab, the shape, size, etc. of the region to be colored are: It can be changed.

  For example, as shown in FIG. 30 (b), one tab T may be divided into left and right, and the divided regions I and II may be colored.

  In addition, when there is a possibility that more colors are added, areas to be colored may be provided on the tabs in a checkered pattern. As an example in this case, FIG. 30C shows a tab T in which regions I to IV are provided in a checkered pattern.

  In addition, the size of the region to which the color is added on the tab may be changeable according to the number of colors to be added, or may be constant regardless of the number of colors to be added.

  That is, in the former case, for example, when one color is assigned to one tab, this color is given to the entire surface of one tab, and in the case of two colors, the tab is divided into two areas. If there are three colors, the tabs are divided into three, and if four colors, the tabs are divided into four, the plurality of colors can be attached to the tabs.

  In the latter case, an area to which these colors are attached is set on the tab by the number of colors that may be attached in advance. For example, when a tab is given a maximum of four colors, as shown in FIG. 30C, if the areas I to IV on the tab T are respectively associated with a predetermined function or color, a certain function selection key is assigned. A plurality of colors can be added on the tab, such as adding a color to the region III when a color is added, or adding a color to the region I when another function is added.

(6) Designation canceling operation In step S29 or S105, when a function selection key is pressed for a long time, it cannot be combined with a function corresponding to this function selection key, and designation to a function that has already been designated Is released. That is, in the above-described form, “long press” is set as the designation cancellation operation. “Long press” means that a key is pressed continuously for a predetermined time or more.

  However, the designation cancellation operation is not limited to this long press, and other operations can be appropriately set as the designation cancellation operation. Other designation release operations include, for example, “continuous pressing”, that is, pressing a key corresponding to a prohibited function for a predetermined number of times.

  The present invention is not limited to the embodiments described above, and various modifications can be made within the scope shown in the claims.
