  Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. First, a first embodiment of the present invention will be described with reference to FIGS. FIG. 1A is a block diagram showing an electrical configuration of a multifunction peripheral device 10 which is an embodiment of the function execution device of the present invention. Hereinafter, the multifunction peripheral device 10 is referred to as “MFP 10”.

  The MFP 10 includes a CPU 11, ROM 12, RAM 13, NVRAM 14, operation keys 15, LCD 16, touch panel 17, scanner unit 18, printer unit 19, NCU 20, modem 21, and network interface (hereinafter referred to as “network I / F”) 22. Is provided. These units are connected to each other via the input / output port 23.

  The CPU 11 controls each function of the MFP 10 and controls each unit connected to the input / output port 23 according to programs and data stored in the ROM 12, RAM 13, NVRAM 14, or various signals transmitted / received via the NCU 20. . The ROM 12 is a read-only memory that stores various programs executed by the CPU 11 and constants and tables that are referred to when the programs are executed. The ROM 12 stores a control program 12a for controlling the operation of the MFP 10. Each process executed by the CPU 11 in the flowcharts of FIGS. 4 and 5 to be described later is a process executed by the CPU 11 according to the control program 12a.

  The RAM 13 is a rewritable volatile memory having a temporary area for temporarily storing various data when the CPU 11 executes the control program 12a. The NVRAM 14 is a nonvolatile RAM. The NVRAM 14 stores an error table 14a described later. The NVRAM 14 also stores image data for displaying various screen images (hereinafter simply referred to as “screens”) on the LCD 16 and tree information that defines the hierarchical structure of each screen. The image data for displaying various screens includes image data of an icon image (hereinafter simply referred to as “icon”).

  The operation key 15 is a mechanical key provided on the casing of the MFP 10 and accepts various setting values and instructions from the user. The LCD 16 is a liquid crystal display device and displays various screens. A touch panel 17 is provided on the LCD 16 so as to overlap the LCD 16. For example, when an indicator such as a finger or a stick touches or approaches the screen of the LCD 16, the touch panel 17 detects the touched or approached position and inputs the detected position to the MFP 10.

  The scanner unit 18 reads a document and converts it into image data. The printer unit 19 prints an image based on the image file on a recording sheet. The modem 21 modulates image data to be transmitted at the time of FAX transmission into a signal that can be transmitted to a telephone line network (not shown) and transmits the signal via the NCU 20 or is input from the telephone line network via the NCU 20. The received signal is demodulated into image data. The NCU 20 controls connection to the telephone line network by closing or disconnecting the line with respect to a telephone line network switch (not shown).

  The network I / F 22 is an interface for communicably connecting to another device via the network 500 by a wired or wireless system. The network 500 is the Internet. The MFP 10 is communicably connected to the server 200 on the network 500 via the network I / F 22. Note that communication between the MFP 10 and the server 200 is performed, for example, according to HTTP (abbreviation of Hypertext Transfer Protocol).

  The MFP 10 which is a multifunction peripheral device is configured to be able to use various functions such as a scan function, a copy function, and a facsimile function. Specifically, for example, the scan function is realized by using the scanner unit 18. The copy function is realized by using the scanner unit 18 and the printer unit 19. The facsimile function is realized mainly using the NCU 20 and the modem 21.

  In the present embodiment, the scan function of the MFP 10 includes a plurality of sub functions. For example, for the scan function, a sub-function corresponding to a difference in processing for read data of a document read by the scanner unit 18 is prepared. For example, “Scan to File”, which is one of the sub-functions constituting the scan function, is a function in which the MFP 10 transmits read data to a specified terminal device and stores it in the terminal device.

  The facsimile function of the MFP 10 has, as sub-functions, for example, a function for receiving a facsimile (hereinafter referred to as “Fax reception function”) and a function for transmitting a facsimile (hereinafter referred to as “Fax transmission function”).

  Hereinafter, a function composed of sub-functions such as a scan function, a copy function, and a facsimile function, or a function composed solely of no sub-functions will be referred to as a “main function”. When the main function is composed of a plurality of sub-functions, the sub-function can be said to be a lower function with respect to the main function.

  Although details will be described later, the MFP 10 according to the present embodiment causes an error from a display mode of an icon associated with the main function for a main function including a plurality of sub functions such as a scan function and a facsimile function. It is configured to be able to distinguish whether there are sub-functions that are not available.

  FIG. 1B is a schematic diagram for explaining the contents of the error table 14a. The error table 14 a is a table that associates errors that have occurred in the MFP 10 with functions that cannot be used due to the errors, and is stored in the NVRAM 14. In the error table 14a, error details 14a2, an associated function 14a3, and an exclusion condition 14a4 are associated with the error type 14a1.

  The error type 14a1 is a category in which errors that have occurred in the MFP 10 are roughly classified. For example, “print error” is one of the categories of the error type 14a1 and is an error related to execution of printing. The error details 14a2 indicates details of errors in the category of the error type 14a1. For example, “paper jam” indicates details of an error in the “printing error” that is the error type 14a1. This “paper jam” refers to a paper jam at the time of conveyance or discharge of the recording paper in the printer unit 19.

  The related function 14a3 is a function that cannot be used due to an error indicated by the error details 14a2. For example, when the error detail 14a2 is “paper jam”, the related function 14a3 stores a value indicating a function that cannot be used due to a paper jam, specifically, a copy function and a fax reception function. The related function 14a3 stores a value indicating a sub function that cannot be used due to an error for a function having a sub function, and indicates a main function that cannot be used due to an error for a main function having no sub function. Stores the value.

  The exclusion condition 14a4 is a setting that is not affected by the error indicated by the error details 14a2 even in the related function 14a3. For example, even if the related function 14a3 is a fax reception function, if the setting (hereinafter referred to as “memory reception setting”) in which the image data received by the fax reception function is not printed and stored in the RAM 13 is on, the fax reception is performed. The function can be used without being affected by a paper jam. That is, when the memory reception setting is set to ON, the fax reception function can be used even when a paper jam occurs.

  The outline of the present invention will be described with reference to the screen transition diagrams of FIGS. The LCD 16 of the present embodiment is configured to have a relatively small size that can display one icon on one screen. On the menu screen 50, icons 51 to 53 for selecting a main function are displayed. That is, the screen image corresponding to the menu screen 50 includes images of icons 51 to 53. In the present specification, a description that an icon is “displayed” on a screen such as the menu screen 50 is synonymous with a description that an icon image is “included” in the screen image in the claims.

  Specifically, the menu screen 50 displays a copy icon 51 for selecting a copy function, a fax icon 52 for selecting a facsimile function, and a scan icon 53 for selecting a scan function. The icons displayed on the menu screen 50 among the icons 51 to 53 can be switched according to a predetermined switching operation. The user can select a function associated with the icons 51 to 53, more specifically, a main function by performing an operation on the icons 51 to 53. Therefore, it can be said that the menu screen 50 is a screen for selecting a main function.

  When an error has occurred in the MFP 10, an error display corresponding to the existence status of functions that cannot be used due to the error is displayed on the menu screen 50. FIG. 2 shows an example in which a paper jam that is one of printing errors occurs. According to the error table 14a, functions that cannot be used due to “paper jam” are a copy function and a fax reception function in which the memory reception setting is off.

  In the present embodiment, when the main function cannot be used at all due to an error that has occurred, the first error display E1 indicating that the function cannot be used at all is displayed in association with the icon of the main function that cannot be used. In the example illustrated in FIG. 2, the first error display E <b> 1 is displayed in a form added to the copy icon 51 for the copy function that cannot be used due to a paper jam.

  When the main function includes a plurality of sub-functions, when a part of the sub-functions constituting the main function cannot be used due to an error that has occurred, a second error display E2 indicating that not all but at least one sub-function can be used. Are displayed in association with the main function including the unavailable sub-function. The second error display E2 is configured as a display having a mode different from the first error display E1. When a paper jam occurs, the fax transmission function in the facsimile function can be used, but the fax transmission function in which the memory reception setting is off cannot be used. In the example shown in FIG. 2, if the memory reception setting is OFF, a second error display E2 is added to the fax icon 52 for a facsimile function in which some functions cannot be used due to a paper jam. Displayed in form.

  When the copy function can be used, a copy execution screen 100 (see FIG. 3), which is a screen for using the copy function, is displayed on the LCD 16 in response to the operation of the copy icon 51. However, if the copy function cannot be used due to an error, even if the copy execution screen 100 is displayed on the LCD 16, the user cannot use the copy function. In the present embodiment, when the copy icon 51 to which the first error display E1 is added is operated, the error notification screen 90 is displayed on the LCD 16 instead of the copy execution screen 100.

  The error notification screen 90 displays a category of errors that have occurred in the MFP 10 and details of the errors. In the example illustrated in FIG. 2, “print error” is displayed as the error category, and “paper jam” is displayed on the error notification screen 90 as the error details. The content corresponding to the error type 14a1 in the error table 14a is displayed as an error category, and the content corresponding to the error details 14a2 is displayed as error details.

  On the other hand, when the fax icon 52 to which the second error display E2 is added is operated, a sub function selection screen 60 for selecting a sub function constituting the facsimile function is displayed on the LCD 16. On the sub-function selection screen 60, icons 61 and 62 for selecting sub-functions constituting the facsimile function are displayed. Specifically, on the sub-function selection screen 60, a Fax reception icon 61 for selecting a Fax reception function that is one of the sub-functions, and a Fax transmission icon for selecting a Fax transmission function that is another sub-function. 62 is displayed. When the fax icon 52 is operated, first, the fax reception icon 61 is displayed on the sub function selection screen 60. In accordance with a predetermined switching operation, the icon displayed on the sub-function selection screen 60 can be switched between the icon 61 and the icon 62.

  Even if a paper jam occurs, the fax transmission function can be used. Therefore, in such a case, a normal fax transmission icon 62 to which no error display is added is displayed on the sub-function selection screen 60. When the fax transmission icon 62 is operated, a fax transmission execution screen 80 that is a screen for using the fax transmission function is displayed on the LCD 16. The details of the fax transmission execution screen 80 are not related to the present invention, and thus the description thereof is omitted.

  On the other hand, when a paper jam occurs, the fax transmission function in which the memory reception setting is off cannot be used. Therefore, the fax reception icon 61 to which the first error display E1 is added is displayed on the sub function selection screen 60. When the fax reception icon 61 to which the first error display E1 is added is operated, the error notification screen 90 is displayed on the LCD 16 in the same manner as when the copy icon 51 to which the first error display E1 is added is operated.

  Even if a paper jam occurs, the scan function can be used. Therefore, in such a case, a normal scan icon 53 without any error display is displayed on the menu screen 50. When the scan icon 53 is operated, a sub function selection screen 70 for selecting a sub function constituting the scan function is displayed on the LCD 16. Although not described in detail because it is not related to the present invention, the sub-function selection screen 70 displays an icon for selecting a sub-function constituting the scan function, similar to the sub-function selection screen 60. On the sub-function selection screen 70, a normal icon without any error display is displayed.

  According to the error table 14a, when a paper jam occurs, the copy function and the fax reception function whose memory reception setting is off cannot be used. In the present embodiment, when the generated error affects two or more main functions, the third error display E3 is displayed on the upper left portion of the menu screen 50. The third error display E3 is configured as a display having a mode different from both the first error display E1 and the second error display E2. The “error affecting the main function” is an error that disables the main function itself or a part or all of the sub-functions constituting the main function. As shown in FIG. 2, the third error display is also displayed on the upper left part of the screen displaying the icons of the sub functions that constitute the main function affected by the error.

  In the present embodiment, the third error display E3 is displayed on the condition that the icon of the main function affected by the error or the icon of the sub function constituting the main function is displayed on the menu screen 50. The The third error display E3 of the present embodiment is a display for notifying an error category that affects two or more main functions.

  In the example shown in FIG. 2, since it is assumed that the memory reception setting is OFF, the fax icon 52 to which the second error display E2 is added is displayed when a paper jam occurs. On the other hand, when the memory reception setting is ON, both the fax transmission function and the fax reception function can be used even when a paper jam occurs. Therefore, in this case, a normal fax icon 52 to which no error display is added is displayed on the menu screen 50.

  FIG. 3 shows an example in which a modem error, which is one of communication errors, has occurred. According to the error table 14a, functions that cannot be used due to a modem error are a fax reception function and a fax transmission function. That is, when a modem error occurs, the facsimile function cannot be used at all. Therefore, in such a case, the first error display E1 is displayed in a form added to the fax icon 52.

  When the fax icon 52 to which the first error display E1 is added is operated, an error notification screen 90 is displayed on the LCD 16. In the example shown in FIG. 3, “communication error” is displayed as the error category, and “modem error” is displayed on the error notification screen 90 as the error details. Since the modem error does not affect the main functions other than the facsimile function, the third error display E3 is not displayed on the menu screen 50.

  Even if a modem error occurs, both the copy function and the scan function can be used. Therefore, in this case, the normal copy icon 51 and scan icon 53 to which no error display is added are displayed on the menu screen 50. In the example of FIG. 3, when the copy icon 51 is operated, the copy execution screen 100 is displayed on the LCD 16. The details of the copy execution screen 100 are not related to the present invention, and thus the description thereof is omitted. On the other hand, when the scan icon 53 is operated, the sub function selection screen 70 is displayed on the LCD 16.

  FIG. 4 is a flowchart showing screen display processing executed by the CPU 11 according to the control program 12a. This process is a process for displaying various screens such as the menu screen 50 on the LCD 16 and is started when the MFP 10 is turned on. The CPU 11 determines whether an error is detected (S401). If the CPU 11 determines that no error is detected (S401: No), the CPU 11 shifts the processing to S403. On the other hand, when the CPU 11 determines that an error is detected (S401: Yes), the CPU 11 acquires error information corresponding to the detected error from error information prepared in advance (S402), and performs processing. The process proceeds to S403.

  In S403, a function selection screen display process is executed. The function selection screen display process (S403) is a process for displaying a screen for selecting a function (hereinafter referred to as “function selection screen”) such as the menu screen 50 and the sub-function selection screens 60 and 70. Details of the function selection screen display process (S403) will be described later with reference to FIG.

  The CPU 11 determines whether at least one function of the operated icon can be used on the function selection screen displayed by the function selection screen display process (S403) (S404). The CPU 11 refers to the error table 14a to determine which function the error indicated by the error information affects in the processing of S404 and the processing of S503, S504, and S506 described later with reference to FIG. To do.

  Specifically, when the operated icon is an icon of a main function having no sub function or an icon of a sub function, the CPU 11 can be used when the main function or the sub function can be used regardless of the presence or absence of an error. Affirms the determination in S404. When the operated icon is a main function icon having a sub function, the CPU 11 affirms the determination in S404 when at least one sub function can be used regardless of the presence or absence of an error.

  On the other hand, when the operated icon is an icon of a main function that does not have a sub function or an icon of a sub function, if the main function or the sub function cannot be used due to an error, the CPU 11 denies the determination in S404. To do. If the operated icon is an icon of a main function having a sub function, the CPU 11 denies the determination in S404 when all the sub functions constituting the main function cannot be used due to an error.

  When the CPU 11 denies the determination of S404, that is, when the function of the operated icon cannot be used at all (S404: No), the CPU 11 displays an error notification screen 90 on the LCD 16 (S409). As described above, the first error display E1 is added to the icon of the function that cannot be used at all. Therefore, when the icon to which the first error display E1 is added is operated, the error notification screen 90 is displayed on the LCD 16 as a result of the process of S409.

  The CPU 11 waits for the corresponding error to be resolved (S410: No). When the CPU 11 determines that the corresponding error has been resolved (S410: Yes), the CPU 11 proceeds to S403 and displays the function selection screen that was displayed immediately before.

  On the other hand, when the CPU 11 affirms the determination in S404 (S404: Yes), the CPU 11 determines whether the next screen to be displayed is a function execution screen according to the operated icon (S405). The function execution screen is a screen for executing functions such as the fax transmission execution screen 80 and the copy execution screen 100. When the CPU 11 determines that the next screen is a function execution screen (S405: Yes), the CPU 11 displays the corresponding function execution screen (S406).

  The CPU 11 waits for the execution button to instruct execution of the function to be operated (S407: No). When the CPU 11 receives an operation on the execution button (S407: Yes), the CPU 11 executes a function corresponding to the operated execution button (S408), shifts the process to S402, and functions to be displayed after the function is executed. The process for displaying the selection screen is started.

  On the other hand, when the CPU 11 determines that the next screen is not a function execution screen (S405: No), the CPU 11 starts processing for displaying a function selection screen to be displayed next in accordance with the operated icon. For example, when the operated icon is a main function icon, a selection screen for selecting a sub function constituting the main function is displayed.

  FIG. 5 is a flowchart showing the above-described function selection screen display process (S403). CPU11 displays the screen except an icon on LCD16 about the function selection screen of a display object (S501). The CPU 11 selects an icon to be displayed this time from the NVRAM 14 (S502). The CPU 11 determines whether at least one function of the icon can be used for the icon to be displayed (S503). The CPU 11 performs the determination in S503 in the same manner as the determination in S404 described above.

  When the CPU 11 denies the determination of S503, that is, when the function of the operated icon cannot be used at all (S503: No), the CPU 11 displays the icon with the first error display E1 added on the function selection screen ( S511), the process proceeds to S506. The image data of the first error display E1 is prepared in the NVRAM 14. As a result of the processing of S511, for example, the Fax reception icon 61 with the first error display E1 shown in FIG. 2 is displayed on the sub-function selection screen 60.

  On the other hand, when the CPU 11 affirms the determination in S503 (S503: Yes), the CPU 11 determines whether or not all the functions of the icon can be used for the icon to be displayed (S504).

  Specifically, when the operated icon is an icon of a main function having no sub function or an icon of a sub function, the CPU 11 can be used when the main function or the sub function can be used regardless of the presence or absence of an error. Affirms the determination in S504. When the operated icon is a main function icon having a sub function, the CPU 11 affirms the determination in step S504 when all the sub functions constituting the main function can be used regardless of whether there is an error. To do. On the other hand, if the operated icon is a main function icon having a sub function, the CPU 11 denies the determination in S504 when some of the sub functions cannot be used due to an error.

  If the CPU 11 denies the determination in S504, that is, if some of the sub-functions cannot be used due to an error (S504: No), the CPU 11 displays an icon with the second error display E2 added on the function selection screen ( S512), the process proceeds to S506. The image data of the second error display E2 is prepared in the NVRAM 14. As a result of the processing of S512, for example, the Fax icon 52 with the second error display E2 shown in FIG.

  On the other hand, when the CPU 11 affirms the determination in S504 (S504: Yes), a normal icon, that is, an icon to which neither the first error display E1 nor the second error display E2 is added is displayed on the function selection screen (S512). ), The process proceeds to S506. As a result of the processing of S512, for example, a normal fax transmission icon 62 shown in FIG. 2 is displayed on the sub-function selection screen 60.

  In step S506, the CPU 11 determines whether there is an error that affects two or more main functions. When the CPU 11 determines that there is a corresponding error (S506: Yes), the CPU 11 determines whether the function of the icon to be displayed belongs to the main function affected by the error (S507). Specifically, when the function of the icon to be displayed is a main function affected by an error, or when it is a sub function constituting the main function, the CPU 11 affirms the determination in S507.

  When the CPU 11 affirms the determination in S507 (S507: Yes), the CPU 11 displays the third error display E3 on the upper left portion of the displayed screen (S508). When the third error display E3 is being displayed, the CPU 11 continues to display the third error display E3. As a result of the processing of S508, for example, as shown in FIG. 2, a third error display E3 is displayed at the upper left part of the menu screen 50 on which the Fax icon 52 is displayed.

  On the other hand, when the CPU 11 determines that there is no error affecting two or more main functions (S506: No), or when the CPU 11 denies determination of S507 (S507: No), the CPU 11 displays the third error display. E3 is deleted from the displayed screen (S513). If the third error display E3 is not displayed, the CPU 11 continues the situation.

  The CPU 11 waits for either an icon switching operation or an icon operation (S509: No, S510: No). When the CPU 11 receives an operation for switching an icon (S509: Yes), the CPU 11 shifts the process to S502 and starts a process of displaying an icon to be displayed next by the switching. On the other hand, when the CPU 11 accepts an operation for an icon (S510: Yes), the CPU 11 ends the process and returns to the screen display process of FIG.

  According to the first embodiment, when all of the plurality of sub-functions constituting the main function cannot be used due to an error, the first error display E1 is added to the icon of the main function. On the other hand, when some of the sub-functions constituting the main function cannot be used due to an error, the second error display E2 is added to the icon of the main function. Therefore, the user can select an error from a plurality of sub-functions constituting the main function corresponding to the icon, depending on whether the first error display E1 or the second error display E2 is added to the icon. It is possible to determine the existence status of sub-functions that cannot be used.

  When all of the plurality of sub-functions constituting the main function cannot be used due to an error, even if a screen corresponding to the operated icon is displayed, the display is only useless. On the other hand, in this embodiment, when the icon to which the first error display E1 is added is operated, the error notification screen 90 is displayed instead of the screen corresponding to the operated icon. Without seeing a useless screen, you can grasp the details of the error that causes the function to be unavailable.

  When an error that affects two or more main functions occurs, the third error display E3 indicating the category of the error is displayed, so that the user has an error that affects two or more main functions. And the category of the error. In particular, the display of the third error display E3 is performed on the condition that the icon of the main function affected by the corresponding error or the icon of the sub function constituting the main function is displayed on the menu screen 50. Therefore, it is easy to identify what is the main function related to the error.

  FIGS. 2 and 3 show the case where the sub-functions constituting the main function are sub-functions one layer lower than the main function, but the above-described screen display processing (FIG. 3) and According to the care selection screen display process (FIG. 4), it is apparent that the present invention can be applied even when a sub-function exists in a lower level of the sub-function. Therefore, when the sub-function icon is a display target, if there are multiple sub-functions that make up the display-target sub-function, and if all of the multiple sub-functions cannot be used due to an error, A first error display E1 is added to the function icon. On the other hand, when some of the plurality of sub functions cannot be used due to an error, the second error display E2 is added to the icon of the sub function to be displayed. That is, regardless of the main function and the sub function, the function of the icon to be displayed corresponds to the “specific function” in the claims.

  Next, a second embodiment of the present invention will be described with reference to FIGS. In the first embodiment described above, various screens such as a function selection screen are displayed on the LCD 16 based on the image data prepared in the NVRAM 14 of the MFP 10.

  Instead, in the second embodiment, a screen according to the screen information received from the server 200 connected to the MFP 10 is displayed on the LCD 16. In the second embodiment, the same parts as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted. Hereinafter, the configuration unique to the second embodiment will be mainly described.

  FIG. 6 is a flowchart illustrating screen display processing according to the second embodiment. This process is a process executed by the CPU 11 according to the control program 12a of the second embodiment. This process is started in response to the CPU 11 receiving an instruction to switch from the server 200 to a mode for receiving screen information.

  When this process is started, the CPU 11 requests screen information from the server 200 on the network 500 via the network I / F 22 (S601). The CPU 11 waits for reception of the screen information transmitted from the requested server 200 (S602: No). When the CPU 11 determines that the screen information has been received from the server 200 (S602: Yes), the CPU 11 shifts the process to S401.

  The screen information that the MFP 10 receives from the server 200 includes image data of each component constituting the display target screen and arrangement information of each component. The icon is a part of each part constituting the screen. Therefore, the image data included in the image information includes icon image data.

  Further, when the display target screen is a function selection screen, the screen information includes information indicating the capability necessary for executing the function of each icon associated with each icon for selecting a function (hereinafter, “ Capability information) ”. The capability information is, for example, information indicating that the function uses a printing function, information indicating that the function uses a scanning function, information indicating that the function uses a transmission / reception function by a modem, and the like. is there.

  On the other hand, the screen information related to the display of the function execution screen does not include capability information. Therefore, in S605, which will be described later, when the capability information is not received from the server 200, the CPU 11 determines that the display target screen is a function execution screen.

  In the screen display process of the present embodiment, the CPU 11 performs the determination in S404 by comparing the capability information associated with the operated icon in the received capability information with the error indicated by the error information. When CPU11 denies determination of S404 (S404: No), CPU11 displays the error notification screen 90 similarly to 1st Embodiment (S409).

  In the present embodiment, a table in which error information is associated with detailed information indicating details of the error indicated by the error information is stored in the NVRAM 14. In step S409, the CPU 11 refers to the table stored in the NVRAM 14 and acquires detailed information corresponding to the error information acquired in step S402. Then, the CPU 11 displays an error notification screen 90 including the acquired detailed information. Therefore, in this embodiment, it is not necessary to request the server 200 for screen information for displaying the error notification screen 90, and it is not necessary to receive the screen information from the server 200. Therefore, the error notification screen 90 can be displayed at an early stage. .

  On the other hand, when the CPU 11 affirms the determination in S404 (S404: No), the CPU 11 notifies the server 200 of information for specifying the operated icon, thereby providing the server 200 with screen information for displaying the next screen. A request is made (S603). The CPU 11 waits for reception of the screen information transmitted from the requested server 200 (S604: No).

  When the CPU 11 determines that the screen information is received from the server 200 (S604: Yes), the CPU 11 determines whether the screen displayed according to the received screen information is a function execution screen (S605). As described above, the CPU 11 determines whether the display target screen is a function execution screen or a function selection screen depending on whether or not capability information is received from the server 200.

  FIG. 7 is a flowchart showing the function selection screen display process (S402) of the second embodiment. CPU11 displays the screen except an icon on LCD16 according to the received screen information instead of S401 (S701).

  In the function selection screen display process (S402) of the present embodiment, the CPU 11 compares the determination in S503 and S504 with the capability information associated with the operated icon in the received capability information and the error indicated by the error information. By doing.

  When the CPU 11 denies the determination of S503, that is, when the function of the operated icon cannot be used at all (S503: No), the CPU 11 displays the icon to be displayed based on the icon image data received as the screen information from the server 200. The first error display E1 is added to the function selection screen (S703). The image data of the first error display E1 is prepared in the NVRAM 14 as in the first embodiment.

  When the CPU 11 denies the determination in S504, that is, when some of the sub-functions cannot be used due to an error (S504: No), the CPU 11 displays the icon to be displayed based on the image data of the icon received as the screen information from the server 200. The second error display E2 is added to the function selection screen (S704). The image data of the second error display E2 is prepared in the NVRAM 14 as in the first embodiment.

According to the present embodiment, since the first error display E1 and the second error display E2 are displayed using the image data prepared in the NVRAM 14, it is not necessary to request the image data from the server 200, and the server There is no need to receive image data from 200. Therefore, the icon to which the first error display E1 or the second error display E2 is added can be displayed at an early stage. When the CPU 11 affirms the determination in S504 (S504: Yes), the CPU 11 receives the icon received as the screen information from the server 200. The display target icon based on the image data is displayed on the function selection screen (S702). As a result of S702, a normal icon, that is, an icon to which neither the first error display E1 nor the second error display E2 is added is displayed.

  In the present embodiment, the CPU 11 determines whether the function of the icon to be displayed uses the main function that is affected by the error, instead of the process of S507 (S705). The CPU 11 makes this determination based on the capability information received from the server 200.

  According to the second embodiment, in the configuration in which the screen according to the screen information received from the server 200 is displayed on the LCD 16, the user can add the first error display E1 to the icon as in the first embodiment. Depending on whether the second error display E2 is added, it is possible to determine the presence status of a sub-function that cannot be used due to an error among a plurality of sub-functions constituting the main function corresponding to the icon.

  Although the present invention has been described based on the embodiments, the present invention is not limited to the above-described embodiments, and various improvements and modifications can be easily made without departing from the spirit of the present invention. Can be inferred.

  For example, in the above-described embodiment, an LCD having a size capable of displaying one icon on one screen is exemplified as the LCD 16. However, the present invention can be similarly applied to an LCD capable of displaying two or more icons on one screen. .

  In the said embodiment, it was set as the structure which displays the 1st error display E1 or the 2nd error display E2 added to the icon. Instead of this, the first error display E1 or the second error display E2 may be configured to display an associated icon in a identifiable manner. For example, a position corresponding to each icon may be assigned in advance, and the first error display E1 or the second error display E2 may be displayed at the position corresponding to the icon to be associated.

  In the above embodiment, the display position of the third error display E3 is the upper left part of the screen, but the display position is not particularly limited. Further, in the above embodiment, the third error display E3 is provided on the condition that the icon of the main function affected by the error or the icon of the sub function constituting the main function is displayed on the menu screen 50. However, if an error that affects two or more main functions occurs, it may be displayed at all times.

  In the above-described embodiment, the third error display E3 is a display that notifies all of the categories of errors that affect two or more main functions, for example, “printing error”, but is affected by the error. When the icon of the main function or the sub function is displayed, the display may be performed so as to identify a function different from the function of the icon being displayed, which is affected by the error. For example, in the example of FIG. 2, the menu screen 50 on which the copy icon 51 is displayed may be configured to display a display indicating that the facsimile function is affected by an error as the third error display E3.

  In the above embodiment, the error notification screen 90 is displayed when the icon to which the first error display E1 is added is operated. However, an error is not displayed on the screen displaying the operated icon, but on a separate screen. It is good also as a structure which performs the display which shows these details.

  In the above embodiment, the case where the function selection screen and the function execution screen are independent from each other has been illustrated, but the present invention can be applied even when an icon for selecting a function is displayed on the screen including the execution button. Applicable.

  In the above embodiment, examples of errors include printing errors such as paper jams and communication errors such as modem errors, but the types of errors are not limited to these. For example, in “Scan to File” exemplified as one of the sub-functions constituting the scan function, when the terminal device to which the read data is to be transmitted is not specified, an example of an error can be obtained. In addition, when the scanner unit 18 includes an automatic document feeder, a paper jam of a document conveyed by the automatic document feeder may be an example of an error.

  In the above embodiment, the case where the memory reception setting is on is exemplified as the exclusion condition 14a4, but the exclusion condition is not limited to this. For example, when the error details 14a2 indicates “out of color ink”, when the setting for printing with black ink when the color ink runs out is on, an example of the exclusion condition may be used.

  In the second embodiment, the first error display E1 and the second error display E2 are displayed using the image data prepared in the NVRAM 14. Instead of this, the image data of the icon to which the first error display E1 is added and the image data of the icon to which the second error display E2 is added are received from the server 200 together with the image data of the normal icon. It is good.

  In this modification, the CPU 11 displays an icon to which the first error display E1 is added based on the image data received from the server 200 in S511. On the other hand, in S512, the CPU 11 displays an icon to which the second error display E2 is added based on the image data received from the server 200. According to this modification, it is possible to omit the process of generating an icon to which the first error display E1 or the second error display is added.

  In the second embodiment, the error notification screen 90 is displayed based on the table stored in the NVRAM 14. However, the screen information for displaying the error notification screen 90 may be received from the server 200. .

  In the said embodiment, although CPU11 demonstrated as a structure which performs each process described in FIGS. 4-7, each process described in these each figure is as a structure which several CPU performs cooperatively. Also good. Further, an IC such as an ASIC may be configured to execute each process described in each of the above drawings independently or in cooperation with a plurality of ICs. Further, the CPU 11 and an IC such as an ASIC may cooperate to execute each process described in the above drawings. Moreover, you may abbreviate | omit or change a one part process among each process shown to FIGS. 4-7 in the range which does not deviate from the independent claim in a claim.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. First, a first embodiment of the present invention will be described with reference to FIGS. FIG. 1A is a block diagram showing an electrical configuration of a multifunction peripheral device 10 which is an embodiment of the function execution device of the present invention. Hereinafter, the multifunction peripheral device 10 is referred to as “MFP 10”.

  The MFP 10 includes a CPU 11, ROM 12, RAM 13, NVRAM 14, operation keys 15, LCD 16, touch panel 17, scanner unit 18, printer unit 19, NCU 20, modem 21, and network interface (hereinafter referred to as “network I / F”) 22. Is provided. These units are connected to each other via the input / output port 23.

  The CPU 11 controls each function of the MFP 10 and controls each unit connected to the input / output port 23 according to programs and data stored in the ROM 12, RAM 13, NVRAM 14, or various signals transmitted / received via the NCU 20. . The ROM 12 is a read-only memory that stores various programs executed by the CPU 11 and constants and tables that are referred to when the programs are executed. The ROM 12 stores a control program 12a for controlling the operation of the MFP 10. Each process executed by the CPU 11 in the flowcharts of FIGS. 4 and 5 to be described later is a process executed by the CPU 11 according to the control program 12a.

  The RAM 13 is a rewritable volatile memory having a temporary area for temporarily storing various data when the CPU 11 executes the control program 12a. The NVRAM 14 is a nonvolatile RAM. The NVRAM 14 stores an error table 14a described later. The NVRAM 14 also stores image data for displaying various screen images (hereinafter simply referred to as “screens”) on the LCD 16 and tree information that defines the hierarchical structure of each screen. The image data for displaying various screens includes image data of an icon image (hereinafter simply referred to as “icon”).

  The operation key 15 is a mechanical key provided on the casing of the MFP 10 and accepts various setting values and instructions from the user. The LCD 16 is a liquid crystal display device and displays various screens. A touch panel 17 is provided on the LCD 16 so as to overlap the LCD 16. For example, when an indicator such as a finger or a stick touches or approaches the screen of the LCD 16, the touch panel 17 detects the touched or approached position and inputs the detected position to the MFP 10.

  The scanner unit 18 reads a document and converts it into image data. The printer unit 19 prints an image based on the image file on a recording sheet. The modem 21 modulates image data to be transmitted at the time of FAX transmission into a signal that can be transmitted to a telephone line network (not shown) and transmits the signal via the NCU 20 or is input from the telephone line network via the NCU 20. The received signal is demodulated into image data. The NCU 20 controls connection to the telephone line network by closing or disconnecting the line with respect to a telephone line network switch (not shown).

  The network I / F 22 is an interface for communicably connecting to another device via the network 500 by a wired or wireless system. The network 500 is the Internet. The MFP 10 is communicably connected to the server 200 on the network 500 via the network I / F 22. Note that communication between the MFP 10 and the server 200 is performed, for example, according to HTTP (abbreviation of Hypertext Transfer Protocol).

  The MFP 10 which is a multifunction peripheral device is configured to be able to use various functions such as a scan function, a copy function, and a facsimile function. Specifically, for example, the scan function is realized by using the scanner unit 18. The copy function is realized by using the scanner unit 18 and the printer unit 19. The facsimile function is realized mainly using the NCU 20 and the modem 21.

  In the present embodiment, the scan function of the MFP 10 includes a plurality of sub functions. For example, for the scan function, a sub-function corresponding to a difference in processing for read data of a document read by the scanner unit 18 is prepared. For example, “Scan to File”, which is one of the sub-functions constituting the scan function, is a function in which the MFP 10 transmits read data to a specified terminal device and stores it in the terminal device.

  The facsimile function of the MFP 10 has, as sub-functions, for example, a function for receiving a facsimile (hereinafter referred to as “Fax reception function”) and a function for transmitting a facsimile (hereinafter referred to as “Fax transmission function”).

  Hereinafter, a function composed of sub-functions such as a scan function, a copy function, and a facsimile function, or a function composed solely of no sub-functions will be referred to as a “main function”. When the main function is composed of a plurality of sub-functions, the sub-function can be said to be a lower function with respect to the main function.

  Although details will be described later, the MFP 10 according to the present embodiment causes an error from a display mode of an icon associated with the main function for a main function including a plurality of sub functions such as a scan function and a facsimile function. It is configured to be able to distinguish whether there are sub-functions that are not available.

  FIG. 1B is a schematic diagram for explaining the contents of the error table 14a. The error table 14 a is a table that associates errors that have occurred in the MFP 10 with functions that cannot be used due to the errors, and is stored in the NVRAM 14. In the error table 14a, error details 14a2, an associated function 14a3, and an exclusion condition 14a4 are associated with the error type 14a1.

  The error type 14a1 is a category in which errors that have occurred in the MFP 10 are roughly classified. For example, “print error” is one of the categories of the error type 14a1 and is an error related to execution of printing. The error details 14a2 indicates details of errors in the category of the error type 14a1. For example, “paper jam” indicates details of an error in the “printing error” that is the error type 14a1. This “paper jam” refers to a paper jam at the time of conveyance or discharge of the recording paper in the printer unit 19.

  The related function 14a3 is a function that cannot be used due to an error indicated by the error details 14a2. For example, when the error detail 14a2 is “paper jam”, the related function 14a3 stores a value indicating a function that cannot be used due to a paper jam, specifically, a copy function and a fax reception function. The related function 14a3 stores a value indicating a sub function that cannot be used due to an error for a function having a sub function, and indicates a main function that cannot be used due to an error for a main function having no sub function. Stores the value.

  The exclusion condition 14a4 is a setting that is not affected by the error indicated by the error details 14a2 even in the related function 14a3. For example, even if the related function 14a3 is a fax reception function, if the setting (hereinafter referred to as “memory reception setting”) in which the image data received by the fax reception function is not printed and stored in the RAM 13 is on, the fax reception is performed. The function can be used without being affected by a paper jam. That is, when the memory reception setting is set to ON, the fax reception function can be used even when a paper jam occurs.

  The outline of the present invention will be described with reference to the screen transition diagrams of FIGS. The LCD 16 of the present embodiment is configured to have a relatively small size that can display one icon on one screen. On the menu screen 50, icons 51 to 53 for selecting a main function are displayed. That is, the screen image corresponding to the menu screen 50 includes images of icons 51 to 53. In the present specification, a description that an icon is “displayed” on a screen such as the menu screen 50 is synonymous with a description that an icon image is “included” in the screen image in the claims.

  Specifically, the menu screen 50 displays a copy icon 51 for selecting a copy function, a fax icon 52 for selecting a facsimile function, and a scan icon 53 for selecting a scan function. The icons displayed on the menu screen 50 among the icons 51 to 53 can be switched according to a predetermined switching operation. The user can select a function associated with the icons 51 to 53, more specifically, a main function by performing an operation on the icons 51 to 53. Therefore, it can be said that the menu screen 50 is a screen for selecting a main function.

  When an error has occurred in the MFP 10, an error display corresponding to the existence status of functions that cannot be used due to the error is displayed on the menu screen 50. FIG. 2 shows an example in which a paper jam that is one of printing errors occurs. According to the error table 14a, functions that cannot be used due to “paper jam” are a copy function and a fax reception function in which the memory reception setting is off.

  In the present embodiment, when the main function cannot be used at all due to an error that has occurred, the first error display E1 indicating that the function cannot be used at all is displayed in association with the icon of the main function that cannot be used. In the example illustrated in FIG. 2, the first error display E <b> 1 is displayed in a form added to the copy icon 51 for the copy function that cannot be used due to a paper jam.

When the main function includes a plurality of sub-functions, when a part of the sub-functions constituting the main function cannot be used due to an error that has occurred, a second error display E2 indicating that not all but at least one sub-function can be used. Are displayed in association with the main function including the unavailable sub-function. The second error display E2 is configured as a display having a mode different from the first error display E1. When a paper jam occurs, the fax transmission function in the facsimile function can be used, but the fax reception function whose memory reception setting is off cannot be used. In the example shown in FIG. 2, if the memory reception setting is OFF, a second error display E2 is added to the fax icon 52 for a facsimile function in which some functions cannot be used due to a paper jam. Displayed in form.

  When the copy function can be used, a copy execution screen 100 (see FIG. 3), which is a screen for using the copy function, is displayed on the LCD 16 in response to the operation of the copy icon 51. However, if the copy function cannot be used due to an error, even if the copy execution screen 100 is displayed on the LCD 16, the user cannot use the copy function. In the present embodiment, when the copy icon 51 to which the first error display E1 is added is operated, the error notification screen 90 is displayed on the LCD 16 instead of the copy execution screen 100.

  The error notification screen 90 displays a category of errors that have occurred in the MFP 10 and details of the errors. In the example illustrated in FIG. 2, “print error” is displayed as the error category, and “paper jam” is displayed on the error notification screen 90 as the error details. The content corresponding to the error type 14a1 in the error table 14a is displayed as an error category, and the content corresponding to the error details 14a2 is displayed as error details.

  On the other hand, when the fax icon 52 to which the second error display E2 is added is operated, a sub function selection screen 60 for selecting a sub function constituting the facsimile function is displayed on the LCD 16. On the sub-function selection screen 60, icons 61 and 62 for selecting sub-functions constituting the facsimile function are displayed. Specifically, on the sub-function selection screen 60, a Fax reception icon 61 for selecting a Fax reception function that is one of the sub-functions, and a Fax transmission icon for selecting a Fax transmission function that is another sub-function. 62 is displayed. When the fax icon 52 is operated, first, the fax reception icon 61 is displayed on the sub function selection screen 60. In accordance with a predetermined switching operation, the icon displayed on the sub-function selection screen 60 can be switched between the icon 61 and the icon 62.

  Even if a paper jam occurs, the fax transmission function can be used. Therefore, in such a case, a normal fax transmission icon 62 to which no error display is added is displayed on the sub-function selection screen 60. When the fax transmission icon 62 is operated, a fax transmission execution screen 80 that is a screen for using the fax transmission function is displayed on the LCD 16. The details of the fax transmission execution screen 80 are not related to the present invention, and thus the description thereof is omitted.

On the other hand, when a paper jam occurs, the fax reception function whose memory reception setting is off cannot be used. Therefore, the fax reception icon 61 to which the first error display E1 is added is displayed on the sub function selection screen 60. When the fax reception icon 61 to which the first error display E1 is added is operated, the error notification screen 90 is displayed on the LCD 16 in the same manner as when the copy icon 51 to which the first error display E1 is added is operated.

  Even if a paper jam occurs, the scan function can be used. Therefore, in such a case, a normal scan icon 53 without any error display is displayed on the menu screen 50. When the scan icon 53 is operated, a sub function selection screen 70 for selecting a sub function constituting the scan function is displayed on the LCD 16. Although not described in detail because it is not related to the present invention, the sub-function selection screen 70 displays an icon for selecting a sub-function constituting the scan function, similar to the sub-function selection screen 60. On the sub-function selection screen 70, a normal icon without any error display is displayed.

  According to the error table 14a, when a paper jam occurs, the copy function and the fax reception function whose memory reception setting is off cannot be used. In the present embodiment, when the generated error affects two or more main functions, the third error display E3 is displayed on the upper left portion of the menu screen 50. The third error display E3 is configured as a display having a mode different from both the first error display E1 and the second error display E2. The “error affecting the main function” is an error that disables the main function itself or a part or all of the sub-functions constituting the main function. As shown in FIG. 2, the third error display is also displayed on the upper left part of the screen displaying the icons of the sub functions that constitute the main function affected by the error.

  In the present embodiment, the third error display E3 is displayed on the condition that the icon of the main function affected by the error or the icon of the sub function constituting the main function is displayed on the menu screen 50. The The third error display E3 of the present embodiment is a display for notifying an error category that affects two or more main functions.

  In the example shown in FIG. 2, since it is assumed that the memory reception setting is OFF, the fax icon 52 to which the second error display E2 is added is displayed when a paper jam occurs. On the other hand, when the memory reception setting is ON, both the fax transmission function and the fax reception function can be used even when a paper jam occurs. Therefore, in this case, a normal fax icon 52 to which no error display is added is displayed on the menu screen 50.

  FIG. 3 shows an example in which a modem error, which is one of communication errors, has occurred. According to the error table 14a, functions that cannot be used due to a modem error are a fax reception function and a fax transmission function. That is, when a modem error occurs, the facsimile function cannot be used at all. Therefore, in such a case, the first error display E1 is displayed in a form added to the fax icon 52.

  When the fax icon 52 to which the first error display E1 is added is operated, an error notification screen 90 is displayed on the LCD 16. In the example shown in FIG. 3, “communication error” is displayed as the error category, and “modem error” is displayed on the error notification screen 90 as the error details. Since the modem error does not affect the main functions other than the facsimile function, the third error display E3 is not displayed on the menu screen 50.

  Even if a modem error occurs, both the copy function and the scan function can be used. Therefore, in this case, the normal copy icon 51 and scan icon 53 to which no error display is added are displayed on the menu screen 50. In the example of FIG. 3, when the copy icon 51 is operated, the copy execution screen 100 is displayed on the LCD 16. The details of the copy execution screen 100 are not related to the present invention, and thus the description thereof is omitted. On the other hand, when the scan icon 53 is operated, the sub function selection screen 70 is displayed on the LCD 16.

  FIG. 4 is a flowchart showing screen display processing executed by the CPU 11 according to the control program 12a. This process is a process for displaying various screens such as the menu screen 50 on the LCD 16 and is started when the MFP 10 is turned on. The CPU 11 determines whether an error is detected (S401). If the CPU 11 determines that no error is detected (S401: No), the CPU 11 shifts the processing to S403. On the other hand, when the CPU 11 determines that an error is detected (S401: Yes), the CPU 11 acquires error information corresponding to the detected error from error information prepared in advance (S402), and performs processing. The process proceeds to S403.

  In S403, a function selection screen display process is executed. The function selection screen display process (S403) is a process for displaying a screen for selecting a function (hereinafter referred to as “function selection screen”) such as the menu screen 50 and the sub-function selection screens 60 and 70. Details of the function selection screen display process (S403) will be described later with reference to FIG.

  The CPU 11 determines whether at least one function of the operated icon can be used on the function selection screen displayed by the function selection screen display process (S403) (S404). The CPU 11 refers to the error table 14a to determine which function the error indicated by the error information affects in the processing of S404 and the processing of S503, S504, and S506 described later with reference to FIG. To do.

  Specifically, when the operated icon is an icon of a main function having no sub function or an icon of a sub function, the CPU 11 can be used when the main function or the sub function can be used regardless of the presence or absence of an error. Affirms the determination in S404. When the operated icon is a main function icon having a sub function, the CPU 11 affirms the determination in S404 when at least one sub function can be used regardless of the presence or absence of an error.

  On the other hand, when the operated icon is an icon of a main function that does not have a sub function or an icon of a sub function, if the main function or the sub function cannot be used due to an error, the CPU 11 denies the determination in S404. To do. If the operated icon is an icon of a main function having a sub function, the CPU 11 denies the determination in S404 when all the sub functions constituting the main function cannot be used due to an error.

  When the CPU 11 denies the determination of S404, that is, when the function of the operated icon cannot be used at all (S404: No), the CPU 11 displays an error notification screen 90 on the LCD 16 (S409). As described above, the first error display E1 is added to the icon of the function that cannot be used at all. Therefore, when the icon to which the first error display E1 is added is operated, the error notification screen 90 is displayed on the LCD 16 as a result of the process of S409.

  The CPU 11 waits for the corresponding error to be resolved (S410: No). When the CPU 11 determines that the corresponding error has been resolved (S410: Yes), the CPU 11 proceeds to S403 and displays the function selection screen that was displayed immediately before.

  On the other hand, when the CPU 11 affirms the determination in S404 (S404: Yes), the CPU 11 determines whether the next screen to be displayed is a function execution screen according to the operated icon (S405). The function execution screen is a screen for executing functions such as the fax transmission execution screen 80 and the copy execution screen 100. When the CPU 11 determines that the next screen is a function execution screen (S405: Yes), the CPU 11 displays the corresponding function execution screen (S406).

  The CPU 11 waits for the execution button to instruct execution of the function to be operated (S407: No). When the CPU 11 receives an operation on the execution button (S407: Yes), the CPU 11 executes a function corresponding to the operated execution button (S408), shifts the process to S402, and functions to be displayed after the function is executed. The process for displaying the selection screen is started.

  On the other hand, when the CPU 11 determines that the next screen is not a function execution screen (S405: No), the CPU 11 starts processing for displaying a function selection screen to be displayed next in accordance with the operated icon. For example, when the operated icon is a main function icon, a selection screen for selecting a sub function constituting the main function is displayed.

  FIG. 5 is a flowchart showing the above-described function selection screen display process (S403). CPU11 displays the screen except an icon on LCD16 about the function selection screen of a display object (S501). The CPU 11 selects an icon to be displayed this time from the NVRAM 14 (S502). The CPU 11 determines whether at least one function of the icon can be used for the icon to be displayed (S503). The CPU 11 performs the determination in S503 in the same manner as the determination in S404 described above.

  When the CPU 11 denies the determination of S503, that is, when the function of the operated icon cannot be used at all (S503: No), the CPU 11 displays the icon with the first error display E1 added on the function selection screen ( S511), the process proceeds to S506. The image data of the first error display E1 is prepared in the NVRAM 14. As a result of the processing of S511, for example, the Fax reception icon 61 with the first error display E1 shown in FIG. 2 is displayed on the sub-function selection screen 60.

  On the other hand, when the CPU 11 affirms the determination in S503 (S503: Yes), the CPU 11 determines whether or not all the functions of the icon can be used for the icon to be displayed (S504).

  Specifically, when the operated icon is an icon of a main function having no sub function or an icon of a sub function, the CPU 11 can be used when the main function or the sub function can be used regardless of the presence or absence of an error. Affirms the determination in S504. When the operated icon is a main function icon having a sub function, the CPU 11 affirms the determination in step S504 when all the sub functions constituting the main function can be used regardless of whether there is an error. To do. On the other hand, if the operated icon is a main function icon having a sub function, the CPU 11 denies the determination in S504 when some of the sub functions cannot be used due to an error.

  If the CPU 11 denies the determination in S504, that is, if some of the sub-functions cannot be used due to an error (S504: No), the CPU 11 displays an icon with the second error display E2 added on the function selection screen ( S512), the process proceeds to S506. The image data of the second error display E2 is prepared in the NVRAM 14. As a result of the processing of S512, for example, the Fax icon 52 with the second error display E2 shown in FIG.

  On the other hand, when the CPU 11 affirms the determination in S504 (S504: Yes), a normal icon, that is, an icon to which neither the first error display E1 nor the second error display E2 is added is displayed on the function selection screen (S512). ), The process proceeds to S506. As a result of the processing of S512, for example, a normal fax transmission icon 62 shown in FIG. 2 is displayed on the sub-function selection screen 60.

  In step S506, the CPU 11 determines whether there is an error that affects two or more main functions. When the CPU 11 determines that there is a corresponding error (S506: Yes), the CPU 11 determines whether the function of the icon to be displayed belongs to the main function affected by the error (S507). Specifically, when the function of the icon to be displayed is a main function affected by an error, or when it is a sub function constituting the main function, the CPU 11 affirms the determination in S507.

  When the CPU 11 affirms the determination in S507 (S507: Yes), the CPU 11 displays the third error display E3 on the upper left portion of the displayed screen (S508). When the third error display E3 is being displayed, the CPU 11 continues to display the third error display E3. As a result of the processing of S508, for example, as shown in FIG. 2, a third error display E3 is displayed at the upper left part of the menu screen 50 on which the Fax icon 52 is displayed.

  On the other hand, when the CPU 11 determines that there is no error affecting two or more main functions (S506: No), or when the CPU 11 denies determination of S507 (S507: No), the CPU 11 displays the third error display. E3 is deleted from the displayed screen (S513). If the third error display E3 is not displayed, the CPU 11 continues the situation.

  The CPU 11 waits for either an icon switching operation or an icon operation (S509: No, S510: No). When the CPU 11 receives an operation for switching an icon (S509: Yes), the CPU 11 shifts the process to S502 and starts a process of displaying an icon to be displayed next by the switching. On the other hand, when the CPU 11 accepts an operation for an icon (S510: Yes), the CPU 11 ends the process and returns to the screen display process of FIG.

  According to the first embodiment, when all of the plurality of sub-functions constituting the main function cannot be used due to an error, the first error display E1 is added to the icon of the main function. On the other hand, when some of the sub-functions constituting the main function cannot be used due to an error, the second error display E2 is added to the icon of the main function. Therefore, the user can select an error from a plurality of sub-functions constituting the main function corresponding to the icon, depending on whether the first error display E1 or the second error display E2 is added to the icon. It is possible to determine the existence status of sub-functions that cannot be used.

  When all of the plurality of sub-functions constituting the main function cannot be used due to an error, even if a screen corresponding to the operated icon is displayed, the display is only useless. On the other hand, in this embodiment, when the icon to which the first error display E1 is added is operated, the error notification screen 90 is displayed instead of the screen corresponding to the operated icon. Without seeing a useless screen, you can grasp the details of the error that causes the function to be unavailable.

  When an error that affects two or more main functions occurs, the third error display E3 indicating the category of the error is displayed, so that the user has an error that affects two or more main functions. And the category of the error. In particular, the display of the third error display E3 is performed on the condition that the icon of the main function affected by the corresponding error or the icon of the sub function constituting the main function is displayed on the menu screen 50. Therefore, it is easy to identify what is the main function related to the error.

FIGS. 2 and 3 show the case where the sub-functions constituting the main function are sub-functions one layer lower than the main function, but the above-described screen display processing (FIG. 3) and According to the function selection screen display process (FIG. 4), it is apparent that the present invention can be applied even when a sub function exists in a lower level of the sub function. Therefore, when the sub-function icon is a display target, if there are multiple sub-functions that make up the display-target sub-function, and if all of the multiple sub-functions cannot be used due to an error, A first error display E1 is added to the function icon. On the other hand, when some of the plurality of sub functions cannot be used due to an error, the second error display E2 is added to the icon of the sub function to be displayed. That is, regardless of the main function and the sub function, the function of the icon to be displayed corresponds to the “specific function” in the claims.

  Next, a second embodiment of the present invention will be described with reference to FIGS. In the first embodiment described above, various screens such as a function selection screen are displayed on the LCD 16 based on the image data prepared in the NVRAM 14 of the MFP 10.

  Instead, in the second embodiment, a screen according to the screen information received from the server 200 connected to the MFP 10 is displayed on the LCD 16. In the second embodiment, the same parts as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted. Hereinafter, the configuration unique to the second embodiment will be mainly described.

  FIG. 6 is a flowchart illustrating screen display processing according to the second embodiment. This process is a process executed by the CPU 11 according to the control program 12a of the second embodiment. This process is started in response to the CPU 11 receiving an instruction to switch from the server 200 to a mode for receiving screen information.

  When this process is started, the CPU 11 requests screen information from the server 200 on the network 500 via the network I / F 22 (S601). The CPU 11 waits for reception of the screen information transmitted from the requested server 200 (S602: No). When the CPU 11 determines that the screen information has been received from the server 200 (S602: Yes), the CPU 11 shifts the process to S401.

  The screen information that the MFP 10 receives from the server 200 includes image data of each component constituting the display target screen and arrangement information of each component. The icon is a part of each part constituting the screen. Therefore, the image data included in the image information includes icon image data.

  Further, when the display target screen is a function selection screen, the screen information includes information indicating the capability necessary for executing the function of each icon associated with each icon for selecting a function (hereinafter, “ Capability information) ”. The capability information is, for example, information indicating that the function uses a printing function, information indicating that the function uses a scanning function, information indicating that the function uses a transmission / reception function by a modem, and the like. is there.

  On the other hand, the screen information related to the display of the function execution screen does not include capability information. Therefore, in S605, which will be described later, when the capability information is not received from the server 200, the CPU 11 determines that the display target screen is a function execution screen.

  In the screen display process of the present embodiment, the CPU 11 performs the determination in S404 by comparing the capability information associated with the operated icon in the received capability information with the error indicated by the error information. When CPU11 denies determination of S404 (S404: No), CPU11 displays the error notification screen 90 similarly to 1st Embodiment (S409).

  In the present embodiment, a table in which error information is associated with detailed information indicating details of the error indicated by the error information is stored in the NVRAM 14. In step S409, the CPU 11 refers to the table stored in the NVRAM 14 and acquires detailed information corresponding to the error information acquired in step S402. Then, the CPU 11 displays an error notification screen 90 including the acquired detailed information. Therefore, in this embodiment, it is not necessary to request the server 200 for screen information for displaying the error notification screen 90, and it is not necessary to receive the screen information from the server 200. Therefore, the error notification screen 90 can be displayed at an early stage. .

  On the other hand, when the CPU 11 affirms the determination in S404 (S404: No), the CPU 11 notifies the server 200 of information for specifying the operated icon, thereby providing the server 200 with screen information for displaying the next screen. A request is made (S603). The CPU 11 waits for reception of the screen information transmitted from the requested server 200 (S604: No).

  When the CPU 11 determines that the screen information is received from the server 200 (S604: Yes), the CPU 11 determines whether the screen displayed according to the received screen information is a function execution screen (S605). As described above, the CPU 11 determines whether the display target screen is a function execution screen or a function selection screen depending on whether or not capability information is received from the server 200.

FIG. 7 is a flowchart showing the function selection screen display process ( S403 ) of the second embodiment. CPU11 displays the screen except an icon on LCD16 according to the received screen information instead of S401 (S701).

In the function selection screen display process ( S403 ) of the present embodiment, the CPU 11 compares the determination in S503 and S504 with the capability information associated with the operated icon in the received capability information and the error indicated by the error information. By doing.

  When the CPU 11 denies the determination of S503, that is, when the function of the operated icon cannot be used at all (S503: No), the CPU 11 displays the icon to be displayed based on the icon image data received as the screen information from the server 200. The first error display E1 is added to the function selection screen (S703). The image data of the first error display E1 is prepared in the NVRAM 14 as in the first embodiment.

  When the CPU 11 denies the determination in S504, that is, when some of the sub-functions cannot be used due to an error (S504: No), the CPU 11 displays the icon to be displayed based on the image data of the icon received as the screen information from the server 200. The second error display E2 is added to the function selection screen (S704). The image data of the second error display E2 is prepared in the NVRAM 14 as in the first embodiment.

According to the present embodiment, since the first error display E1 and the second error display E2 are displayed using the image data prepared in the NVRAM 14, it is not necessary to request the image data from the server 200, and the server There is no need to receive image data from 200. Therefore, the icon to which the first error display E1 or the second error display E2 is added can be displayed at an early stage. When the CPU 11 affirms the determination in S504 (S504: Yes), the CPU 11 receives the icon received as the screen information from the server 200. The display target icon based on the image data is displayed on the function selection screen (S702). As a result of S702, a normal icon, that is, an icon to which neither the first error display E1 nor the second error display E2 is added is displayed.

  In the present embodiment, the CPU 11 determines whether the function of the icon to be displayed uses the main function that is affected by the error, instead of the process of S507 (S705). The CPU 11 makes this determination based on the capability information received from the server 200.

  According to the second embodiment, in the configuration in which the screen according to the screen information received from the server 200 is displayed on the LCD 16, the user can add the first error display E1 to the icon as in the first embodiment. Depending on whether the second error display E2 is added, it is possible to determine the presence status of a sub-function that cannot be used due to an error among a plurality of sub-functions constituting the main function corresponding to the icon.

  For example, in the above-described embodiment, an LCD having a size capable of displaying one icon on one screen is exemplified as the LCD 16. However, the present invention can be similarly applied to an LCD capable of displaying two or more icons on one screen. .

  In the said embodiment, it was set as the structure which displays the 1st error display E1 or the 2nd error display E2 added to the icon. Instead of this, the first error display E1 or the second error display E2 may be configured to display an associated icon in a identifiable manner. For example, a position corresponding to each icon may be assigned in advance, and the first error display E1 or the second error display E2 may be displayed at the position corresponding to the icon to be associated.

  In the above embodiment, the display position of the third error display E3 is the upper left part of the screen, but the display position is not particularly limited. Further, in the above embodiment, the third error display E3 is provided on the condition that the icon of the main function affected by the error or the icon of the sub function constituting the main function is displayed on the menu screen 50. However, if an error that affects two or more main functions occurs, it may be displayed at all times.

  In the above-described embodiment, the third error display E3 is a display that notifies all of the categories of errors that affect two or more main functions, for example, “printing error”, but is affected by the error. When the icon of the main function or the sub function is displayed, the display may be performed so as to identify a function different from the function of the icon being displayed, which is affected by the error. For example, in the example of FIG. 2, the menu screen 50 on which the copy icon 51 is displayed may be configured to display a display indicating that the facsimile function is affected by an error as the third error display E3.

  In the above embodiment, the error notification screen 90 is displayed when the icon to which the first error display E1 is added is operated. However, an error is not displayed on the screen displaying the operated icon, but on a separate screen. It is good also as a structure which performs the display which shows these details.

  In the above embodiment, the case where the function selection screen and the function execution screen are independent from each other has been illustrated, but the present invention can be applied even when an icon for selecting a function is displayed on the screen including the execution button. Applicable.

  In the above embodiment, examples of errors include printing errors such as paper jams and communication errors such as modem errors, but the types of errors are not limited to these. For example, in “Scan to File” exemplified as one of the sub-functions constituting the scan function, when the terminal device to which the read data is to be transmitted is not specified, an example of an error can be obtained. In addition, when the scanner unit 18 includes an automatic document feeder, a paper jam of a document conveyed by the automatic document feeder may be an example of an error.

  In the above embodiment, the case where the memory reception setting is on is exemplified as the exclusion condition 14a4, but the exclusion condition is not limited to this. For example, when the error details 14a2 indicates “out of color ink”, when the setting for printing with black ink when the color ink runs out is on, an example of the exclusion condition may be used.

  In the second embodiment, the first error display E1 and the second error display E2 are displayed using the image data prepared in the NVRAM 14. Instead of this, the image data of the icon to which the first error display E1 is added and the image data of the icon to which the second error display E2 is added are received from the server 200 together with the image data of the normal icon. It is good.
