  Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a block diagram showing an electrical configuration of a multifunction peripheral device (hereinafter referred to as “MFP (Multi Function Peripheral)”) 10 which is an embodiment of the input device of the present invention. The MFP 10 is a multifunction machine having various functions such as a printer function, a copy function, and a scan function. In particular, the MFP 10 according to the present embodiment is configured to prevent the user's operability from being impaired even when the user performs an operation such that one text is not specified on the software keyboard.

  The MFP 10 mainly includes a CPU 11, a flash memory 12, a RAM 13, an operation key 14, an LCD 15, a touch panel 16, a scanner 17, a printer 18, and a LAN I / F 19, which are connected to each other via a bus line 21.

  The CPU 11 controls functions of the MFP 10 and each unit connected to the bus line 21 according to fixed values and programs stored in the flash memory 12, data stored in the RAM 13, and the like. The flash memory 12 is a rewritable nonvolatile memory in which a control program 12a for controlling the operation of the MFP 10, a correction history table 12b, and the like are stored. The CPU 11 executes a text input process (FIG. 5) to be described later according to the control program 12a. The correction history table 12b will be described later with reference to FIG.

  The RAM 13 is a rewritable volatile memory and stores an input text table 13a. The input text table 13a will be described later with reference to FIG.

  The operation key 14 is a hard key, and inputs various information and instructions to the MFP 10. The LCD 15 is a liquid crystal display device. On the display surface of the LCD 15, a capacitive touch panel 16 is provided. The scanner 17 is a device that reads an original and generates image data of the read original. The printer 18 is a device that prints an image on recording paper. The LAN I / F 19 is an interface for communicably connecting the MFP 10 and other devices via a LAN (not shown).

  A text input operation method in the MFP 10 will be described with reference to FIGS. FIG. 2A is a diagram illustrating an example of a text input screen displayed on the LCD 15 of the MFP 10. The text input screen includes a software keyboard SK, a text display unit TE, a confirmation button BT1, and a cancel button BT2.

  The software keyboard SK includes a plurality of key areas K, and one text is assigned to each key area K. When the user operates the software keyboard SK, the MFP 10 specifies the text designated by the software keyboard SK based on the signal input from the touch panel 16. Specifically, the MFP 10 operates based on the coordinates of each key area K stored in advance and the coordinates corresponding to the signal input from the touch panel 16 (that is, the coordinates indicating the position at which contact is detected). The assigned key area K is determined, and the key assigned to the key area K is specified as the designated text.

  Then, the specified text is displayed on the text display unit TE in a predetermined display color (for example, black). For example, as shown in FIG. 2B, when the text “b” is designated on the software keyboard SK, the text “b” is displayed on the text display unit TE. By repeating the operation of the software keyboard SK, the user can create a text string composed of the input text and display it on the text display unit TE.

  Here, a case where a plurality of texts are specified by the user operating a plurality of key areas K of the software keyboard SK will be described. In this case, the MFP 10 causes the text display unit TE to display one text among a plurality of texts specified based on the user operation in a special display color (for example, red). FIG. 2C illustrates an example in which one text “c” is displayed on the text display unit TE in a special display color when two texts “c, d” are specified based on a user operation. Is shown.

  In this way, the user continues the operation of the software keyboard SK for the time being without worrying about whether one text has been specified by the operation or whether a plurality of texts have been specified. By checking the text string, it is possible to recognize an operation that has specified a plurality of texts, and to easily find an erroneous input.

  That is, when text is input by operating the software keyboard SK, there is no feedback to the fingertip, unlike the case of hard keys. Therefore, the user performs an operation while gazing at the software keyboard SK. According to the MFP 10 of the present embodiment, the user inputs text by looking at only the software keyboard SK, inputs some text, and then visually recognizes the text string on the text display unit TE, thereby making an erroneous input. Can be recognized collectively (text displayed in a special display color).

  Therefore, even when the user performs an operation such that one text is not specified during the input of the text string, the user does not interrupt the text input operation or visually recognize the text display unit TE. In addition, the text input operation can be continued. Therefore, it can suppress that a user's operativity is impaired.

  In the following description, text specified by a single operation (pressing) on the software keyboard SK is referred to as simultaneous input text. Displaying text in a special display color is referred to as highlighting. Displaying text in a normal display color is referred to as normal display.

  FIG. 3 is a diagram for explaining a text string correction method in the MFP 10. As described with reference to FIG. 2, in the text display unit TE, the highlighted text may be erroneously input. Therefore, the specification for the highlighted text is accepted. Then, the simultaneous input text corresponding to the designated text is displayed on the LCD 15 as the correction candidate N. For example, in the example shown in FIG. 3A, when the highlighted text “c” is designated (pressed) by the user, the simultaneous input text “c, d” corresponding to the text is changed to the correction candidate N. Display as.

  When an operation for selecting one of the correction candidates N is received, the highlighted text specified in the text display unit TE is changed to the text selected from the correction candidates N. For example, in the example shown in FIG. 3, the highlighted text “c” designated in the text display unit TE is changed to the text “d” selected from the correction candidates N (see FIG. 3B). As shown in FIG. 3B, the corrected text is also highlighted.

  As described above, the user can recognize whether or not the correction candidate N exists based on the display color of the text on the text display unit TE. The simultaneous input text can be visually recognized as the correction candidate N by a simple operation of designating the highlighted text. Furthermore, the highlighted text specified in the text display unit TE can be changed to the text selected from the correction candidates N by a simple operation of selecting one of the correction candidates N. Therefore, the correction of the text is easy and the operability is good.

  In this way, when the input and correction of the text string is completed, the user instructs to confirm the text input by pressing the confirm button BT1. When input confirmation is instructed, the MFP 10 finishes accepting text input and stores the text string displayed on the text display unit TE. On the other hand, when the user wants to delete the input text string, the user instructs the deletion of the text string by pressing the cancel button BT2. In this case, the text string is not stored.

  As shown in FIG. 3, the correction candidate N is preferably displayed in a size larger than the key area K in the software keyboard SK. In this way, the user can grasp at a glance the difference between the correction candidate N and the software keyboard SK, and can easily select the correction candidate N.

  FIG. 4A is a diagram schematically showing the configuration of the correction history table 12b. The correction history table 12b stores history information indicating a history of text changes in the text display unit TE. The history information is information in which the simultaneous input text, the appropriate text, and the number of corrections are associated with each other.

  The simultaneous input text storage unit 30 includes first to fourth text storage units 30a, 30b, 30c, and 30d, and stores a maximum of four texts as simultaneous input texts. When the text first displayed on the text display unit TE among the simultaneously input text is corrected by the user, the appropriate text storage unit 31 stores the corrected text as the appropriate text.

  The correction count storage unit 32 stores a correction count indicating the number of times the appropriate text has been selected from a combination of a plurality of texts indicated in the simultaneous input text. For example, in the history information in the first column shown in FIG. 4A, among the text “c, d” specified as the simultaneous input text, “d” is first displayed on the text display unit TE. This means that the number of times of correction to “c” is 10 times. On the other hand, in the history information in the second column, among the texts “c, d” specified as the simultaneous input text, “c” is first displayed on the text display unit TE, but finally becomes “d”. This means that the number of corrections is 13 times.

  FIG. 4B is a diagram schematically showing the configuration of the input text table 13a. The input text table 13a is a table that stores simultaneous input text in association with text to be displayed on the text display unit TE, and includes a display input number storage unit 41 and a simultaneous input text storage unit 42.

  The simultaneous input text storage unit 42 includes first to fourth text storage units 42a, 42b, 42c, and 42d, and stores the simultaneous input text (that is, text specified by one operation on the software keyboard SK). . Of the simultaneous input text, the text stored in the first text storage unit 42a is hereinafter referred to as the first text. When one simultaneous input text is specified based on the user operation, the one text is determined as the first text. When a plurality of simultaneous input texts are specified based on a user operation, one text is determined as the first text from the plurality of simultaneous input texts and is displayed first on the text display unit TE. . A method for determining the first text will be described later with reference to FIG.

  The display input number storage unit 41 stores a display input number indicating which of the simultaneous input texts is being displayed on the text display unit TE. For example, when the display input number is 1, it means that the first text among the simultaneous input texts is being displayed on the text display unit TE. When the display input number is not 1, it means that text other than the first text is being displayed. That is, it means that the first text displayed as the first text has been changed to another text by the user's will.

  Information in which the simultaneous input text is associated with the display input number is referred to as input information. In the input text table 13a, the position where the input information is stored corresponds to the display position of each text on the text display unit TE. Specifically, the text specified by the input information stored in the nth row of the input text table 13a is displayed nth from the top in the text display unit TE.

  FIG. 5 is a flowchart showing text input processing executed in the MFP 10. This process is a process for accepting an operation on the text input screen (FIG. 2), and is executed when the MFP 10 starts accepting a text input.

  First, the CPU 11 clears the input text table 13a (S501), and displays the software keyboard SK on the text input screen (S502). If the touch panel 16 is not operated (S503: No), the CPU 11 does not proceed to the next step. On the other hand, when the touch panel is operated (S503: Yes), the CPU 11 determines whether or not a process is assigned to the operation position (S504). When no process is assigned to the operation position (S504: No), the CPU 11 repeats the process from S503.

  When the process is assigned to the operation position (S504: Yes) and the operation position is on the software keyboard SK (S505: Yes), the CPU 11 executes the input result display process (S506), and returns to S503. The input result display process (S506) is a process for displaying the text specified based on the user operation on the text display unit TE, and details will be described later with reference to FIG.

  When the operation position is not on the software keyboard SK (S505: No) but on the text display unit TE (S507: Yes), the CPU 11 determines whether there is a highlighted text at the operation position (S508). If the highlighted text is present at the operation position (S508: Yes), that is, if designation for the highlighted text is received, the CPU 11 executes input correction processing (S509), and returns to S503. The input correction process (S509) is a process of correcting the highlighted text specified in the text display unit TE, and details will be described later with reference to FIG. If there is no highlighted text at the operation position on the text display unit TE (S508: No), the CPU 11 skips S509 and returns to S503.

  When the operation position is not on the text display unit TE (S507: No) but on the confirmation button BT1 (S510: Yes), the CPU 11 changes whether or not the highlighted text has been corrected, that is, changes the first text. It is determined whether or not an operation has been performed (S511). Specifically, it is determined whether or not there is input information whose display input number is not 1 in the input text table 13a.

  When it is determined that an operation for changing the first text has been performed (S511: Yes), the CPU 11 executes a history update process (S514). The history information update process (S514) is a process for updating the history information, and details will be described later with reference to FIG. On the other hand, when there is no change in the first text (S511: No), the CPU 11 skips S514. Then, the CPU 11 stores the confirmed text string in, for example, the flash memory 12 (S515).

  When the operation position is not on the confirm button BT1 (S510: No) but on the cancel button BT2 (S512: Yes), the CPU 11 skips S511, S514, and S515, and proceeds to S516. Then, the CPU 11 hides the software keyboard SK (S516) and ends the process.

  If the operation position is not on the cancel button BT2 (S512: No), the CPU 11 executes other processing corresponding to the operation position (S513), and returns to the processing of S503.

  FIG. 6 is a flowchart showing the input result display process. This process is a process of displaying text specified based on a user operation on the text display unit TE.

  First, the CPU 11 specifies the text specified on the software keyboard SK based on the signal input from the touch panel 16 (S600). When a plurality of texts are specified (S601: Yes), history information including simultaneous input texts having the same combination as the specified plurality of texts is acquired from the correction history table 12b (S605). This process will be described with reference to FIG. For example, when “c, d” is specified as a plurality of texts, history information including two texts “c” and “d” as simultaneous input texts is acquired from the correction history table 12b.

  Returning to FIG. Next, in the acquired history information, there is one history information in which the number of corrections is a predetermined value (for example, 15) or more (S606: Yes) and the number of corrections is a predetermined value or more. When the only text exists (S607: No), the CPU 11 determines the appropriate text indicated by the history information as the first text (S608). That is, the text selected as the appropriate text more than a predetermined number of times among the simultaneously input texts having the same combination as the plurality of texts specified this time is determined as the first text.

  For example, in the correction history table 12b shown in FIG. 4A, two pieces of history information including the simultaneous input text “c, d” are stored. Of these, the history information whose correction count is 15 or more is only the history information in the first row. Therefore, the appropriate text “d” indicated by the history information on the first line is determined as the first text.

  Returning to FIG. If there is a plurality of pieces of history information whose number of corrections is greater than or equal to a predetermined value (S607: Yes), and there is one piece of history information with the maximum number of corrections (S609: Yes), the CPU 11 indicates the history information. The appropriate text to be used is determined as the first text (S610). That is, the text that has been selected as the appropriate text from the simultaneous input texts of the same combination as the plurality of texts specified this time is determined as the first text.

  By determining the first text based on the history information, an appropriate first text based on the past change history can be determined and presented to the user. Here, the appropriate first text means text that is unlikely to be modified by the user. That is, the trouble of text correction is suppressed by first displaying the text most likely to be selected by the user as the first text based on the history of past changes.

  On the other hand, when there are a plurality of pieces of history information with the maximum number of corrections (S609: No), or when there is no history information with the number of corrections equal to or greater than a predetermined value (S606: No), the CPU 11 The text corresponding to the key area K having the largest contact area is determined as the first text (S611). If it does in this way, the suitable 1st text according to user operation can be determined, and it can present to a user.

  Next, the CPU 11 generates input information including the simultaneous input text and stores it in the input text table 13a (S612). For example, when “c, d” is specified as the simultaneous input text, and “c” is determined as the first text, the input information illustrated in the third line of FIG. The first text “c” is stored in the first text storage unit 42a in the input text table 13a, and “d” is stored in the second text storage unit 42b. The display input number storage unit 41 stores “1” indicating that the first text is displayed. Then, the CPU 11 highlights the first text on the text display unit TE (S613), and ends this process.

  On the other hand, when a single text is specified based on a signal input from the touch panel 16 (S601: No), the CPU 11 determines the specified text as the first text (S602), generates input information, and inputs it. It is stored in the text table (S603). Note that the input information generated in this case includes only one text as the simultaneous input text. Then, the CPU 11 normally displays the first text on the text display unit TE (S604), and ends this process.

  According to the input result display process, even if a plurality of texts are specified based on the user operating a plurality of key areas K, the determination is made based on the history information or the contact area for the user. 1 text (first text) can be presented. In addition, since the first text is highlighted, it is possible to make the user recognize that there is a correction candidate corresponding to the first text.

  FIG. 7 is a flowchart showing the input correction process. This process is a process of displaying the correction candidate N when the designation for the highlighted text is received and correcting the designated text to the text selected from the correction candidates N.

  First, the CPU 11 acquires input information corresponding to the designated highlighted text from the input text table 13a (S701). Then, the CPU 11 displays the simultaneous input text included in the acquired input information on the LCD 15 as the correction candidate N, and accepts an operation for selecting one of the correction candidates N (S702). Then, while the correction candidate N is not selected (S703: No), the CPU 11 does not proceed to the next step.

  On the other hand, when the correction candidate N is selected (pressed) (S703: Yes), the CPU 11 hides the correction candidate N (S704). Then, the CPU 11 determines whether or not an instruction to change the text is given (S705). Specifically, it is determined whether the text selected by the user from the correction candidate text N is different from the highlighted text specified by the user in the text display unit TE.

  When the text selected by the user from the correction candidate text N is different from the highlighted text specified by the user in the text display unit TE (S705: Yes), the CPU 11 updates the display of the text display unit TE (S706). The highlighted text designated by the user is changed to the text selected from the correction candidate text N by the user. Specifically, the display input number is changed to a number indicating the text selected by the user, and the display on the text display unit TE is updated based on the changed input information. The changed text is also highlighted.

  On the other hand, when the text selected by the user from the correction candidate text N is the same as the text specified by the user in the text display unit TE (S705: No), the CPU 11 skips S706 and ends the process. To do. That is, the input information and the display on the text display unit TE are not updated.

  FIG. 8 is a flowchart showing a history update process executed in the MFP 10. This process is a process of updating the history information when there is a text displayed by changing the first text when the text input confirmation is instructed.

  First, the CPU 11 specifies input information corresponding to the corrected text (S801). Specifically, one piece of input information whose display input number is not 1 is specified among the input information stored in the input text table 13a.

  Next, the CPU 11 determines whether there is history information corresponding to the specified input information (S802). Specifically, the history information including the simultaneous input text included in the input information and the simultaneous input text of the same combination and including the same text as the corrected text as the appropriate text is stored in the correction history table 12b. It is judged whether it is done.

  If there is history information corresponding to the input information (S802: Yes), that is, if the same correction as this time has been made in the past for the combination of the correction candidates N and the appropriate text finally selected by the user, the input information 1 is added to the number of revisions of the history information corresponding to (S803).

  On the other hand, when there is no history information corresponding to the input information (S802: No), the history information corresponding to the input information is added to the correction history table 12b and stored (S804). Specifically, the simultaneous input text included in the specified input information is stored in the correction history table 12b, the corrected text being displayed specified by the display input number is stored as an appropriate text, and the number of corrections is “ 1 ”is stored.

  Then, it is determined whether or not all the corrected text has been processed (S805). If the determination is negative (S805: No), the CPU 11 repeats the processing from S801. When the determination in S801 is affirmed while the process is repeated in this manner (S805: Yes), the CPU 11 ends the process.

  According to the history update process, when there is a text displayed by changing the first text at the time when the input confirmation of the text string is instructed, the history information is updated for the text. History information reflecting the final intention can be stored.

  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, the specific numerical values given in the above embodiment are merely examples, and other numerical values can naturally be adopted. For example, the predetermined number of times in S606 in FIG. Further, the correction history table 12b and the input text table 13a may be configured to be able to store less than 4 or 5 or more texts as simultaneous input texts.

  In the above-described embodiment, the MFP 10 has been described as an example of the input device. However, various devices such as a printer, a scanner, a mobile phone, a smartphone, a PDA, a tablet terminal, and a digital camera may be examples of the input device.

  Moreover, in the said embodiment, the text corresponding to the key area K with the largest contact area was determined as a 1st text (S611 of FIG. 6). Alternatively, the text corresponding to the position operated earliest may be determined as the first text. Further, the text corresponding to the position operated until the latest may be determined as the first text. Even in these modified examples, an appropriate text corresponding to the user operation can be presented to the user as the first text.

  Moreover, in the said embodiment, when the text which the user specified in the text display part TE and the text which the user selected from the correction candidates N are the same, it demonstrated as what does not update the display of the text display part TE. (S705 in FIG. 7). Instead, when a text is selected from among the correction candidates N, the text display unit TE is irrespective of whether or not the selected text is the same as the text specified in the text display unit TE. The display at may be updated.

  In the above embodiment, one of the plurality of identified texts is determined as the first text and displayed on the text display unit TE. However, two or more texts are displayed on the text display unit TE. Also good.

  In the above embodiment, when a single text is specified based on a signal input from the touch panel 16, the text is displayed in a normal display color, and when a plurality of texts are specified, the plurality of texts are displayed. In the above description, it is assumed that one text is displayed in a special display color. However, for example, it is possible to visually distinguish one by highlighting one in bold or lighting it.

  Moreover, although the alphabet was illustrated as an example of a text in the said embodiment, a text is not restricted to a character, A symbol, a word, a pictogram, etc. may be sufficient.

  In the above embodiment, the correction candidate N is displayed so as to overlap the display area of the software keyboard SK. For example, the key area K corresponding to the correction candidate N among the key areas K included in the software keyboard SK. It is also possible to display the correction candidate N by accepting only the key area K and invalidating the other key area K, and accept the selection.

  Moreover, in the said embodiment, when the correction frequency of several historical information is the same, the text corresponding to the key area | region K with the largest contact area was determined as a 1st text. Alternatively, an appropriate text of one piece of history information (for example, history information stored at the smallest memory address) among a plurality of pieces of history information having the same number of corrections may be determined as the first text.

  Further, in the above embodiment, when a plurality of texts are specified based on a user operation, one text among the plurality of texts is highlighted. However, the above embodiment may be modified so that the one text is normally displayed. However, in this modification, when the one text is specified in the text display unit TE, the simultaneous input text stored in association with the text is displayed as the correction candidate N. In this way, the user can visually recognize the correction candidate N by a simple operation of designating simultaneously input text, and the correction work is easy.

  Further, in the above-described embodiment, when one text among a plurality of texts is highlighted, the correction candidate N is displayed on the condition that the text is designated. However, the display of the correction candidate N is not indispensable, and the highlight candidate may be simply displayed.

  Moreover, in the said embodiment, although operation which selects either from the correction candidates N was detected with the touch panel 6, this operation does not necessarily need to be detected with a touch panel. For example, the above embodiment may be modified so that the correction candidate N is selected by the user inputting the number assigned to the correction candidate N from a hard key. Similarly, the operation for designating the text displayed on the text display unit TE is not necessarily detected by the touch panel.
