Description

  The present invention relates to an information processing apparatus, an information processing method, and an information processing program.

  Japanese Patent Application Laid-Open No. 2004-151620 discloses a technique for displaying a warning on a display unit when an incorrect operation or setting is performed in a copying apparatus, or displaying an error when a paper jam or the like occurs.

JP 2001-290393 (abstract, claim)

  By the way, in the information processing apparatus, a large number of screens corresponding to many situations are prepared. For this reason, when each of these many screens is displayed, when an incorrect operation is performed (for example, an invalid key is operated), an attempt is made to realize a process of displaying a warning or an error on the display unit. Then, the processing becomes complicated and the coding amount of the program becomes enormous.

  In other words, in order to execute the processing as described above, a valid or invalid key type is registered in each existing screen, and a warning or error display format (number of lines, display width, etc.) is displayed on each screen. Must be set. Conventionally, since a program for executing these processes is described for each screen, the process becomes complicated as described above, and the coding amount of the program becomes enormous.

  In addition, when there is a change in the display format or the like, it is necessary to modify all of these programs, which causes a problem that the amount of work becomes enormous.

  The present invention has been made based on the above circumstances, and its purpose is to reduce the coding amount of a program that displays information indicating that an erroneous operation has been performed, and when a correction occurs. Is intended to provide an information processing apparatus, an information processing method, and an information processing program that can be handled with a small amount of work.

  In order to achieve the above object, an information processing apparatus according to the present invention includes a registration unit that divides information for generating a screen to be displayed on a display unit into a plurality of hierarchies, and a plurality of registration units registered in the registration unit. By drawing means for executing drawing processing based on hierarchy information, display means for displaying a screen obtained by the drawing means on a display unit, an input device for generating and outputting information according to an operation, and a display means When a predetermined screen is displayed, a determination unit for determining whether the information input by operating the input device is valid or invalid, and a case where the determination unit determines that invalid information is input from the input device Is a control for registering information for displaying invalid information indicating that invalid input has been made in a predetermined hierarchy of the registration unit and causing the drawing unit to execute a drawing process. It has a stage, a. Accordingly, it is possible to provide an information processing apparatus that can reduce the coding amount of a program that displays information indicating that an erroneous operation has been performed, and that can cope with a small amount of work when a correction occurs.

  In addition to the above-described invention, in the information processing apparatus of another invention, the drawing unit draws information registered in the registration unit in a predetermined order for each hierarchy, and the control unit displays invalid information. The information for registration is registered in the hierarchy drawn at the end of the registration means. For this reason, the information superimposed on the invalid information can be saved, restored, and the processing can be omitted, so that the processing can be speeded up and the coding amount can be reduced.

  Further, in addition to the above-described invention, the information processing apparatus according to another aspect of the invention may include other information displayed in the area where the control unit displays invalid information on the display unit. The invalid information is registered so that the invalid information is displayed in a display format corresponding to the display format. For this reason, when the display is switched from other information to invalid information, or when the display is switched from invalid information to other information, it is possible to prevent the user from feeling uncomfortable.

  In addition to the above-described invention, the information processing apparatus according to another aspect of the invention may be configured so that the control unit invalid information registered in the registration unit when a predetermined time has elapsed since the invalid information was displayed on the display unit. The information for displaying is deleted or invalidated, and the drawing means is made to execute the drawing process again. For this reason, when a certain period of time has elapsed, invalid information can be erased from the screen, so that visual recognition of other information is not hindered.

  In addition to the above-described invention, the information processing apparatus according to another aspect of the invention provides information for displaying invalid information to the registration unit when the control unit determines that invalid information is input by the determination unit. If it is determined that valid information has been entered, the information for displaying invalid information is deleted or invalidated from the registration means, and the drawing means registers the information for displaying invalid information in the registration means. If it is, the drawing process for the information for displaying the invalid information is executed. For this reason, the processing speed can be improved by executing the drawing process only when invalid information is registered.

  In addition, the information processing method of the present invention registers information for generating a screen to be displayed on the display unit in a plurality of layers, executes drawing processing based on the information of the plurality of registered layers, The screen obtained by the drawing process is displayed on the display unit, and when a predetermined screen is displayed by the display process, the input device is operated to determine whether the input information is valid or invalid, and invalid information is displayed. When it is determined that the input has been made from the input device, information for displaying invalid information indicating that invalid input has been made is registered in a predetermined hierarchy and a drawing process is executed. Thus, it is possible to provide an information processing method that can reduce the coding amount of a program that displays information indicating that an erroneous operation has been performed and that can cope with a small amount of work when correction occurs.

  Also, the information processing program of the present invention includes a registration unit for registering information for generating a screen to be displayed on the display unit in a plurality of hierarchies, and drawing based on information of the plurality of hierarchies registered in the registration unit. A drawing means for executing processing, a display means for displaying a screen obtained by the drawing means on a display unit, an input device for generating and outputting information according to an operation, and when a predetermined screen is displayed by the display means A determination unit that determines whether the information input by operating the input device is valid or invalid; if the determination unit determines that invalid information is input from the input device, it indicates that invalid input has been made. A computer as control means for registering information for displaying invalid information in a predetermined hierarchy of the registration means and causing the drawing means to execute drawing processing To function. As a result, it is possible to reduce the coding amount of a program that displays information indicating that an erroneous operation has been performed, and to provide an information processing program that can cope with a small amount of work when correction occurs.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a diagram illustrating a configuration example of a printing apparatus 10 according to an embodiment of the present invention. The information processing apparatus according to the present invention will be described using the printing apparatus 10 as an example. The information processing method and information processing program of the present invention will be described as operations of the printing apparatus 10.

  A printing apparatus 10 illustrated in FIG. 1 is a so-called composite printing apparatus in which a scanner apparatus, a printing apparatus, and a copying apparatus are integrated. The printing apparatus 10 includes a main control unit 20, an information input unit 30, an information output unit 40, a printing mechanism 50, and a scanning mechanism 60 as main components.

  The main control unit 20 includes an input / output control unit 20a, a card I / F (Interface) 20b, a control unit 20c, a memory 20d, an image processing unit 20e, a printer control unit 20f, a buffer 20g, and a scanner control unit 20h. The information output unit 40, the print mechanism 50, the scan mechanism 60, and the like are controlled based on information input from the information input unit 30.

  The input / output control unit 20a serving as a display unit is an interface that appropriately converts the data representation format when information is exchanged between the information input unit 30 and the information output unit 40. When the memory card 70 is inserted, the card I / F 20b executes processing for reading image data from the memory card 70 and writing image data. The memory card 70 is constituted by, for example, a flash memory, and stores image data photographed by a digital camera (not shown), for example.

  The control unit 20c is configured by a CPU (Central Processing Unit), for example, and controls each unit of the apparatus based on a program 20d1 stored in the memory 20d. The image processing unit 20e performs, for example, image processing on the image data supplied from the control unit 20c. The printer control unit 20f controls the printing mechanism 50, for example, prints image data on printing paper. The buffer 20g temporarily stores the image data subjected to the image processing by the image processing unit 20e, and temporarily stores the image data input from the scanner control unit 20h. The scanner control unit 20h controls the scan mechanism 60 and executes processing for reading image data printed on printing paper.

  The information input unit 30 as an input device uses the operation keys 30a and the touch panel 30b as main components, and generates and outputs information based on user operations. Here, the operation key 30a is a button arranged on an operation panel or the like, and generates and outputs information corresponding to a user operation. The touch panel 30b is arranged so as to be superimposed on an LCD (Liquid Crystal Display) 40a, and position information corresponding to the operated position is output by operating the touch panel 30b based on information displayed on the LCD 40a. .

  The information output unit 40 includes the LCD 40a and the lamp 40b as main components, and outputs information to be presented to the user. Here, the LCD 40a is superimposed on the touch panel 30b as described above, and displays the image data supplied from the control unit 20c. The lamp 40b is arranged on an operation panel or the like, and indicates predetermined information to the user by turning on / off under the control of the control unit 20c.

  The print mechanism 50 includes a recording head 50a, a scanning unit 50b, and a paper transport unit 50c as main components, and prints image data supplied from the control unit 20c on a printing paper. Here, the recording head 50a, for example, appropriately ejects ink of each color corresponding to CMYK from a plurality of nozzles, and prints an image corresponding to printing paper. The scanning unit 50b moves the recording head 50a in the main scanning direction (a direction orthogonal to the direction in which nozzles of the same color are arranged). The paper transport unit 50c moves the printing paper in the sub-scanning direction (direction orthogonal to the main scanning direction).

  The scanning mechanism 60 has a light source 60a, a light receiving unit 60b, and a scanning unit 60c as main components, optically reads an image printed on a document, and generates and outputs corresponding image data. Here, the light source 60a is constituted by, for example, a cold cathode tube, and irradiates white light to an area of the original to be read. The light receiving unit 60b is configured by a CCD (Charge Coupled Device) or the like that receives the light irradiated by the light source 60a and reflected by the document and converts it into a corresponding electrical signal. The scanning unit 60c moves the light receiving unit 60b in the sub-scanning direction (a direction orthogonal to the longitudinal direction of the light receiving unit 60b).

  FIG. 2 is a diagram illustrating an example of functional modules related to display realized in the printing apparatus 10 when the program 20d1 stored in the memory 20d of the printing apparatus 10 illustrated in FIG. 1 is executed. Note that the functional modules shown in FIG. 2 are realized by the cooperation of a program 20d1 as a software resource and hardware resources including the control unit 20c.

  As shown in FIG. 2, the control module 100 and the display management module 110 are included as functional modules related to display. Here, the control module 100 as a registration unit, a determination unit, and a control unit generates information for displaying a screen according to a change in the state of the information processing apparatus, and supplies the information to the display management module 110.

  The display management module 110 executes a drawing process based on the information supplied by the control module 100 and supplies it to the input / output control unit 20a.

  The display management module 110 includes a layer group including an image display layer 111, a normal guide display layer 112, and an invalid guide display layer 113, and a screen management module 114.

  Here, the image display layer 111 is a layer in which information for displaying, for example, an image to be printed is registered on the LCD 40a. The normal guide display layer 112 is a layer in which information for displaying a normal guide (guide other than an error or warning) is registered. The invalid guide display layer 113 is a layer in which information for displaying an invalid guide (invalid information) as information indicating that an invalid key has been operated is registered.

  The screen management module 114 executes a drawing process based on the information registered in the layer group, synthesizes the obtained images, and supplies them to the input / output control unit 20a.

  Next, the operation of the above embodiment will be described. Hereinafter, the conventional invalid guide drawing process will be described, and then the invalid guide drawing process according to the embodiment of the present invention will be described.

  FIG. 3 is a flowchart illustrating a conventional invalid guide drawing process. When the processing of this flowchart is started, the following steps are executed. The following processing will be described as processing related to an information processing apparatus having a control unit, a display unit, a storage unit, and an operation unit.

  Step S10: The control unit determines whether or not a predetermined key of the operation unit has been operated. If the operation unit has been operated, the process proceeds to step S11. Otherwise, the same process is repeated.

  Step S11: The control unit determines whether or not the operated key is an effective key at that time, and proceeds to step S16 when determining that the operated key is an effective key, and otherwise. Proceed to step S12.

  Step S12: The control unit stores the normal guide (details will be described later) currently displayed on the display unit in the storage unit. FIG. 4A is an example of a screen displayed on the display unit at this time. This example is a screen displayed during printing, “Information” is displayed as the title of the screen, “Printing in progress” is displayed below it, and details of its operation are “ A total of 1 sheet is left. "Is displayed. Below that, a normal guide (a guide for explaining keys related to print cancellation and reserved printing) is displayed as information about the key. In step S12, the normal guide displayed at the bottom of the screen is acquired and stored in the storage unit.

  Step S13: The control unit changes the normal guide to an invalid guide indicating that an invalid key has been pressed. Then, the process proceeds to step S18. In the processing after step S18, drawing processing and display processing are executed as described later, and as a result, a screen as shown in FIG. 4B is displayed on the display unit. In this example, “Invalid key pressed” is displayed as an invalid guide at the bottom of the screen.

  Step S14: The control unit activates an invalid guide display timer for counting the time during which the invalid guide is displayed. In addition, as time to measure by this timer, sufficient time for a user to confirm an invalid guide should just be ensured. For example, 5 seconds is set as the time counted by the timer. Then, when the set time has elapsed, the timer generates a timeout, and the process proceeds to step S15.

  Step S15: The control unit proceeds to step S16 when the invalid guide display timer has timed out (when the set time has been counted).

  Step S16: The control unit executes a process of returning the invalid guide displayed on the display unit to the original normal guide. Specifically, the control unit acquires the normal guide stored in the storage unit in step S12.

  Step S17: The control unit stops the invalid guide display timer. Thereby, for example, when a valid key is operated while the invalid guide display timer is counting, the timer is stopped. Then, the process proceeds to step S18. In the processing after step S18, drawing processing and display processing are executed as described later, and as a result, a screen as shown in FIG. 4C is displayed on the display unit. In this example, a normal guide as information about keys is displayed at the bottom of the screen.

  Step S18: The control unit performs drawing processing for a screen including an invalid guide when the process proceeds from step S14, and performs processing for rendering a screen including a normal guide when the process proceeds from step S17.

  Step S19: The control unit displays the screen obtained by the drawing process in step S18 on the display unit. As a result, the screen shown in FIG. 4B or 4C is displayed on the display unit.

  Next, the operation of the embodiment of the present invention will be described. In the following, the operation of the functional block shown in FIG. 2 will be described first, and then the flow of processing related to the invalid guide will be described based on the flowchart shown in FIG.

  FIG. 5 shows an example of information registered in each layer constituting the layer group shown in FIG. 2 (hereinafter referred to as “registration information”). In this example, the registration information includes a drawing flag 150, a page ID (Identification) 151, a screen creation processing function pointer 152, parameter information 153, and drawing size information 154. It should be noted that information other than these may be included, or some of these information may not exist.

  Here, the drawing flag 150 is information indicating whether or not to draw the layer. For example, when this information is set to “Enable”, the screen management module 114 draws the layer, and when this information is set to “Disable”, the screen management module 114 does not draw the layer. .

  The page ID 151 is information indicating a unique ID assigned to each screen, and is configured by information such as “0x0-0xffff”, for example.

  The screen creation processing function pointer 152 is a pointer that indicates a drawing function to be called when the drawing flag 151 is set to Enable.

  The parameter information 153 is information indicating whether full-screen drawing or partial drawing is to be performed and the ID of a part to be drawn in the case of partial drawing.

  The drawing size information 154 is information indicating the size of the screen to be drawn. In this example, the upper left coordinates (x, y) of the rectangular area to be drawn, and information indicating the width (w) and height (h) of the rectangular area are configured. This information speeds up the process by not performing the drawing process of the layer when all of the layer is obscured by a layer that is higher than the layer (drawn later). It becomes the standard of judgment when making.

  Next, an operation in the case of performing a drawing process using registration information as shown in FIG. 5 will be described. In the present embodiment, a desired screen can be obtained by registering registration information to be drawn for each layer of the layer group shown in FIG.

  For example, in order to obtain a screen as shown in FIG. 6C, registration information for displaying the information shown in FIG. 6A is registered in the image display layer 111 by the control module 100. Registration information for displaying the information shown in FIG. 6B is registered in the normal guide display layer 112 by the control module 100. At this time, the drawing flags of the image display layer 111 and the normal guide display layer 112 are both set to “Enable”.

  At this time, since no invalid guide is displayed, no information is registered in the invalid guide display layer 113. The drawing flag 150 of the invalid guide display layer 113 is set to Disable.

  When the drawing information is registered after the registration information as described above is registered in each layer, the screen management module 114 first performs a drawing process based on the registration information registered in the image display layer 111. Execute. As a result, the screen management module 114 calls a function indicated by the pointer registered in the screen creation processing function pointer 152 and executes the drawing process. As a result, an image as shown in FIG. 6A is generated.

  Next, the screen management module 114 executes a drawing process based on the registration information registered in the normal guide display layer 112. As a result, the screen management module 114 calls a function indicated by the pointer registered in the screen creation processing function pointer 152 and executes the drawing process. As a result, an image as shown in FIG. 6B is generated and overwritten on the image shown in FIG. 6A, so that an image as shown in FIG. 6C is obtained.

  The image obtained in this way is supplied to the input / output control unit 20a. The input / output control unit 20a converts the image supplied from the display management module 110 into a video signal, supplies it to the LCD 40a, and displays it. As a result, a screen as shown in FIG. 6C is displayed on the display unit of the LCD 40a.

  Next, with reference to FIG. 7, an invalid key determination process when a screen as shown in FIG. 6C is displayed on the LCD 40a will be described. When the processing of this flowchart is started, the following steps are executed. At this time, registration information for displaying the information shown in FIG. 8A is registered in the image display layer 111, and the normal guide display layer 112 has the registration information shown in FIG. ) Is registered, and a screen as shown in FIG. 6C is displayed on the LCD 40a.

  Step S30: The control module 100 determines whether or not a key operation has been performed, that is, whether or not the operation key 30a or the touch panel 30b has been operated. If any of these has been performed, the process proceeds to step S31. In this case, the same processing is repeated.

  Step S31: The control module 100 determines whether or not a valid key has been operated. Whether the key is valid or not is determined as an invalid key for keys other than those that can be input on the currently displayed screen.

  Step S32: The control module 100 registers, in the invalid guide display layer 113, registration information for displaying an invalid guide as information indicating that an invalid key has been operated. At this time, the drawing flag 150 of the registration information registered in the invalid guide display layer 113 is set to “Enable”, and information as shown in FIG. 8C is displayed as the screen creation processing function pointer 152. A pointer that points to a function to register is registered.

  Step S33: The control module 100 starts an invalid guide display timer (not shown). Specifically, the control module 100 sets, for example, a value for counting 5 seconds as an initial value in the invalid guide display timer, and starts a counting operation. When the counting operation is completed, the invalid guide display timer generates a time-out, and as a result, processing in step S34 described later is started.

  Step S34: When a timeout occurs in the invalid guide display timer, the control module 100 proceeds to the process of step S35 via this process. Specifically, if the above-described 5 seconds have elapsed, the process proceeds to step S35.

  Step S35: The control module 100 deletes the registration information registered in the invalid guide display layer 113 and sets the drawing flag 150 to Disable. As a result, the invalid guide is erased from the display unit of the LCD 40a.

  Step S36: The control module 100 stops the operation of the invalid guide display timer. That is, when the valid key is operated again while the invalid guide is displayed, the operation of the invalid guide display timer is stopped by this processing.

  Step S37: The screen management module 114 executes screen drawing processing. That is, the screen management module 114 first refers to the drawing flag 150 of the registration information registered in the image display layer 111, and since it is enabled, the function indicated by the screen creation processing function pointer 152 The drawing process is executed based on the above. As a result, the image shown in FIG. 8A is obtained. Next, the screen management module 114 refers to the drawing flag 150 of the registration information registered in the normal guide display layer 112, and since it is “Enable”, the function designated by the screen creation processing function pointer 152 is used. Based on this, the drawing process is executed. As a result, the image shown in FIG. 8B is obtained. Since the drawing process based on the normal guide display layer 112 is overwritten on the image of the image display layer 111, an image as shown in FIG. 6C is obtained as a result of the drawing process.

  Step S38: The screen management module 114 determines whether or not the registration information exists in the invalid guide display layer 113. If it exists, the process proceeds to step S39. Otherwise, the process proceeds to step S40. Specifically, the drawing flag 150 of the invalid guide display layer 113 is referred to. If the drawing flag 150 is set to Enable, the process proceeds to step S39, and otherwise, the process proceeds to step S40.

  Step S39: The screen management module 114 executes a drawing process based on the registration information registered in the invalid guide display layer 113. Specifically, the following processing is executed. That is, the screen management module 114 first acquires the drawing size information 154 from the registration information stored in the normal guide display layer 112. Then, using the drawing size information 154 as an argument, a function indicated by the screen creation processing function pointer 152 of the registration information of the invalid guide display layer 113 is called to execute drawing processing. As a result, information as shown in FIG. 8C is drawn (overwritten) in the same area as the normal guide. Since the area where the normal guide is drawn and the area where the invalid guide is drawn are the same, the normal guide is erased by overwriting, and only the invalid guide is visible. As a result, an image as shown in FIG. 8D is obtained.

  At this time, the display format of the invalid guide may be matched with that of the normal guide. For example, the number of lines and the display width where the invalid guide is displayed may be the same as that of the normal guide. By doing this, when the display is switched from the normal guide to the invalid guide, or when the display is switched from the invalid guide to the normal guide, the user feels uncomfortable, the characters hide other information, Or it can prevent that a character protrudes from a screen.

  Step S40: The screen management module 114 supplies the image obtained by the drawing process to the input / output control unit 20a. The input / output control unit 20a displays the supplied image on the display unit of the LCD 40a. As a result, a screen including an invalid guide as shown in FIG. 8D is displayed on the display unit of the LCD 40a.

  Next, the process of the flowchart shown in FIG. 7 will be described with a specific example.

  If an invalid key is operated while a screen as shown in FIG. 6C is displayed on the LCD 40a, first, “Y” is determined in step S30, and then the process proceeds to step S31, where It determines with "N" and progresses to step S32.

  In step S32, registration information for displaying an image as shown in FIG. 8C, for example, is registered in the invalid guide display layer 113, and the drawing flag 150 is set to Enable. Next, the process proceeds to step S33, the invalid guide display timer is started, and the process proceeds to step S37.

  In step S37, a drawing process based on registration information registered in the image display layer 111 and the normal guide display layer 112 is executed, and as a result, a screen as shown in FIG. 6C is generated.

  In subsequent step S38, since the registration information exists in the invalid guide display layer 113, it is determined “Y”, and the process proceeds to step S39. In step S39, the invalid guide drawing process is executed. As described above, in this process, since the invalid guide is drawn so as to be superimposed on the normal guide, only the invalid guide is visible. In step S40, display processing is executed. As a result, a screen as shown in FIG. 8D is displayed on the LCD 40a.

  In such a state, when the counting of the time set in step S14 is completed, the invalid guide display timer generates a timeout, and the process proceeds to step S35 via step S34. In step S35, the information registered in the invalid guide display layer 113 is deleted, and the drawing flag 150 is set to Disable. In step S36, the invalid guide display timer is stopped.

  In subsequent step S37, a drawing process is performed on the registered information registered in the image display layer 111 and the normal guide display layer 112, and as a result, an image as shown in FIG. 6C is drawn. .

  In step S38, since the drawing flag 150 of the invalid guide display layer 113 is set to Disable, the process proceeds to step S40. As a result, the screen shown in FIG. 6C is displayed on the LCD 40a. Invalid guides are not displayed.

  According to the above processing, when the invalid key is operated, the invalid guide is displayed for a certain time, and when a timeout occurs, the original screen is restored.

  If the valid key is operated before the timeout occurs, “Y” is determined in step S31, and the processes in steps S35 to S37, S38, and S40 are executed. The invalid guide is deleted from the screen.

  As described above, in the embodiment of the present invention, a plurality of layers are provided, information to be displayed is registered for each layer, and an invalid guide indicating that an invalid key has been operated is provided. I set it as one of these layers. For this reason, the amount of program coding can be drastically reduced by making the processing for displaying each screen common. Specifically, in the conventional process shown in FIG. 3, it is necessary to describe the processes of S11 to S18 as a program for each screen. On the other hand, in the processing according to the present invention shown in FIG. 7, only the processing of S31 and S37 may be described as a program for each screen.

  Further, in the embodiment of the present invention, the invalid guide is superimposed and drawn on the normal guide so that only the invalid guide can be visually recognized. Since it is not necessary to restore (S12) or restore (S16), the processing can be speeded up and the coding amount of the program can be reduced.

  In the embodiment of the present invention, the display area and display format of the invalid guide are the same as those of the normal guide. For example, when the display is switched from the normal guide to the invalid guide, or from the invalid guide to the normal guide. It is possible to prevent the user from feeling uncomfortable by changing the display format when the display is switched.

  In the embodiment of the present invention, the invalid guide is deleted from the screen when a certain amount of time has passed since the invalid guide is displayed. Can be prevented. Further, the process of deleting the invalid guide can be realized only by deleting the registration information from the invalid guide display layer 113 (by simply setting the drawing flag to Disable), so that the process can be speeded up. Further, during the printing process, it is possible to prevent the printing process from being burdened by the process for deleting the invalid guide.

  In the embodiment of the present invention, the drawing process is executed only when the registration information is set in the invalid guide display layer 113. Therefore, the drawing process is performed when the registration information is not set. By not executing the processing, the processing speed can be increased.

  The above embodiment is merely an example, and there are various other modified embodiments.

The registration information may be registered according to the above and the drawing process may be executed.

  In the above embodiment, registration information as shown in FIG. 5 is registered in each layer, but other information may be registered. For example, only part of the information shown in FIG. 5 may be used, or other information may be added to part or all of the information shown in FIG.

  In the above embodiment, the invalidity guidance is displayed when an invalid key is operated. For example, when the print paper is not appropriate or a paper jam occurs, It is also possible to display error guidance in the same way as.

  In the above embodiment, the invalid guide indicating that the invalid key has been operated is displayed. For example, the valid guide indicating that the valid key has been operated is displayed in the same manner as described above. You may make it display by the method of.

  Further, the screens shown in FIGS. 6 and 8 are examples, and it is needless to say that screens other than these can be displayed.

  In the flowchart shown in FIG. 7, the invalid guide display timer is activated when an invalid guide is displayed, and the invalid guide is deleted when a timeout occurs. The invalid guide may remain displayed until the next operation is performed on the information input unit 30 without being activated.

  Further, in the flowchart shown in FIG. 7, in step S38, it is determined whether or not the invalid guide is drawn depending on whether or not the registration information exists in the invalid guide display layer. However, the processing in step S38 may be omitted, and only the layer for which the drawing flag is enabled may be drawn.

  The above processing functions can be realized by a computer. In that case, a program describing the processing contents of the functions that the information processing apparatus should have is provided. By executing the program on a computer, the above processing functions are realized on the computer. The program describing the processing contents can be recorded on a computer-readable recording medium. Examples of the computer-readable recording medium include a magnetic recording device, an optical disk, a magneto-optical recording medium, and a semiconductor memory. Examples of the magnetic recording device include a hard disk device (HDD), a flexible disk (FD), and a magnetic tape. Examples of the optical disc include a DVD (Digital Versatile Disk), a DVD-RAM, a CD-ROM (Compact Disk ROM), and a CD-R (Recordable) / RW (ReWritable). Magneto-optical recording media include MO (Magneto-Optical disk).

  When distributing the program, for example, portable recording media such as a DVD and a CD-ROM in which the program is recorded are sold. It is also possible to store the program in a storage device of a server computer and transfer the program from the server computer to another computer via a network.

  The computer that executes the program stores, for example, the program recorded on the portable recording medium or the program transferred from the server computer in its own storage device. Then, the computer reads the program from its own storage device and executes processing according to the program. The computer can also read the program directly from the portable recording medium and execute processing according to the program. In addition, each time the program is transferred from the server computer, the computer can sequentially execute processing according to the received program.
