Description

  The present invention relates to a data input device for inputting data, and more particularly to a technique for easily inputting data in a data input device equipped with coordinate detection display means such as a touch panel.

  A method of displaying the keyboard on the screen and capturing the key content by pointing to the keyboard (software keyboard) is widely adopted. In this software keyboard, a touch panel is formed on the surface of the display screen, and a touch with a finger, an input pen, or the like is detected, or a mouse click is detected to make a key input.

2. Description of the Related Art Conventionally, there is known a technique for displaying adjacent characters when pointing to one key. FIG. 28 shows a conventional technique example.
When inputting hiragana, a keyboard as shown in FIG. 28 is displayed on the display 24. For example, when a “one” key is touched by touching the touch panel 28 with a pen or a finger, “z” and “t” are adjacent to the “one” key as shown in FIG. The key is displayed. After touching “tsu”, the touch is moved to the “z” or “tsu” key, and when the touch is finished on these keys, the character positioned when the touch is finished is input.

JP 2002-91676 A

In the prior art, related character keys are displayed at the position adjacent to the touched key so as to cover the surrounding keys. Then, the keys around the touched key are hidden by the related character key. Therefore, after a certain key is touched, it is not possible to perform an operation to reselect a key located around the key.
In this specification, the technique which can eliminate such inconvenience is provided.

  The data input device of the present application includes a coordinate detection display unit having a function of detecting an instruction coordinate touched or approached by an indicator and a function of displaying various data, and a process based on the instruction coordinate detected by the coordinate detection display unit It is a data input device that performs. First button data storage means for storing first button data and second button data storage means for storing second button data are provided. First conversion filter data storage means for storing first conversion filter data is provided. First correspondence information storage means for storing first correspondence information indicating correspondence between the first button data and the first conversion filter data is provided. First conversion information storage means for storing first conversion information indicating the correspondence between the first conversion filter data and the second button data is provided. A plurality of first button areas are defined in the coordinate detection display means, and first button display control means for displaying first button data in each first button area is provided. 1st filter data which specifies the 1st conversion filter data corresponding to the 1st button data in the 1st button field based on the 1st correspondence information when directions coordinates are located in any 1st button field A specifying means is provided. There is provided first empty area forming means for creating a first empty area in which no other first button area is displayed around the first button area where the designated coordinates are located. First conversion filter display control means for defining a first conversion filter area in the first empty area and displaying the first conversion filter data in the first conversion filter area is provided. When the designated coordinates are located in any of the first conversion filter regions, a first conversion unit is provided that specifies the second button data corresponding to the first conversion filter data based on the first conversion information. A first data input unit is provided for inputting data corresponding to the second button data when a predetermined condition is satisfied in a state where the second button data is specified.

Examples of the indicator include a user's finger and a stylus (touch panel pen). Examples of the first and second button data storage means, the first conversion filter data storage means, the first correspondence information storage means, and the first conversion information storage means include a storage device such as a ROM. Examples of the first and second button data include character data such as hiragana, alphabet, and numbers, and various function data such as space key and delete. The first correspondence information may be a table representing the correspondence between the first button data and the first conversion filter data.
The first conversion information may be a table representing the correspondence between the first conversion filter data and the second button data. The determination as to whether or not the designated coordinates are located in any button area may be performed by, for example, comparing the coordinates for determining the button area with the designated coordinates. There are various methods for forming the first empty area by the first empty area forming means. For example, the other first button area may be moved, or the other first button area may be reduced and displayed. The timing at which the first empty area forming unit forms the first empty area may be various. For example, an empty area may be formed in advance between all the first button areas, or a first empty area may be formed each time the first button area is pressed.

  There may be a plurality of first conversion filter regions. As an example of the first conversion filter data, there are filters that convert to different types of characters (such as conversion between hiragana and katakana), and filters that change the size of characters (such as conversion that changes the number of character points). Can be mentioned. First conversion filter data corresponding to the first button data is specified based on the first correspondence information. Further, the second button data corresponding to the first conversion filter data is specified based on the first conversion information. Thus, the first button data is converted to the second button data. As an example of button data conversion, when the character type of the button data is hiragana and the conversion filter data is conversion of hiragana and katakana character types, an operation of converting hiragana to katakana can be cited. When the confirmation operation for confirming the button data displayed in the button area is performed, the data input process for one character is completed.

  When a predetermined condition is satisfied, an input process for inputting data corresponding to the second button data is performed. The predetermined condition includes, for example, a condition that the designated coordinates are located within the fixed area.

  According to the data input device described in the present application, the first conversion filter area is displayed in the first empty area. Accordingly, it is possible to prevent a situation in which the other first button area displayed around the first button area where the designated coordinates are located is hidden by the first conversion filter area. Therefore, even when the user presses the wrong first button area, it is possible to easily re-select the correct first button area located around the wrong first button area.

Further, according to the data input device described in the present application, the periphery of the first button area is set as the display prohibited area by the display prohibiting unit. Further, the moving means moves the other first button area so that it is located outside the display prohibition area.
Therefore, it is possible to form an empty area by moving the other first button areas radially around the first button area where the designated coordinates are located.

  Moreover, according to the data input device described in the present application, the other first button area is returned to the original position in response to the establishment of the predetermined condition. Thus, each time the conversion operation is completed, the other first button areas are returned to their original positions, so that the arrangement of the first button areas is returned to the initial state. Therefore, since it becomes easy to search for the next desired first button area, it is possible to improve the convenience for the user.

  Further, according to the data input device described in the present application, the periphery of the first button area is set as the display prohibition area by the display prohibition unit. Further, the reduction means displays the reduced first button area so that it is positioned outside the display prohibition area. Therefore, the first free area can be formed. And since it is not necessary to move the position of another 1st button area, the arrangement of the 1st button area is maintained in the initial state. Therefore, since it becomes easy to search for a desired first button region, it is possible to improve user convenience.

  Further, according to the data input device described in the present application, the other first button area is returned to the original size in response to the establishment of the predetermined condition. As a result, each time the conversion operation ends, the other first button area returns to its original size, so that it becomes easy to find the next desired first button area. Therefore, user convenience can be improved.

  Further, according to the data input device described in the present application, both the first conversion filter data and the second conversion filter data can be applied to one button data. Therefore, since a plurality of types of conversion filter data can be applied to one button data, complicated conversion contents can be implemented. For example, even when the first button data is hiragana (for example, “hi”), it is converted to a character (for example, “bi”) that is both a muddy sound and a prompt sound, It becomes possible to convert. And since the 1st and 2nd conversion filter area | region for performing conversion operation is displayed around the 1st and 2nd button area | region, conversion operation can be performed easily.

  An empty area is formed around the second button area. Therefore, since the first button area located around the second button area is not hidden by the second conversion filter area, it is possible to easily select another first button area. As described above, since it is possible to perform complicated conversion contents with a simple operation, it is possible to improve user convenience.

  Further, according to the data input device described in the present application, the second button region is determined at a position based on the designated coordinates. For example, the second button area may be determined with the designated coordinates as the center point. Thereby, for example, when the user operates the touch panel with a finger, when the user selects the first conversion filter area with the finger, the converted button data is displayed at the position of the fingertip. Further, the second conversion filter data is displayed around the fingertip. Therefore, when selecting the second conversion filter data next time, the distance to move the finger may be short, so that the convenience for the user can be improved.

  A first embodiment will be described with reference to the drawings. FIG. 1 shows an external view and a configuration diagram of the multi-function device 10. The multi-function device 10 has a printer function, a scanner function, a copy function, a facsimile function, a telephone function, and the like. As shown in FIG. 1, a display panel 50 is provided on the upper surface front side of the multi-function device 10. The display panel 50 is a so-called touch panel. The display panel 50 has a function of detecting instruction coordinates where a user's finger or a stylus (touch panel pen) is touched or approached. The display panel 50 may be a touch panel that detects only contact. The display panel 50 has a function of displaying various data. On the display panel 50, for example, various touch panel buttons such as a character button (such as hiragana and alphabet), a menu button, a phone book button, and a history button are displayed.

  The configuration diagram of FIG. 1 will be described. The multi-function device 10 includes a control unit 12, a display panel 50, hard keys 52, a printing unit 54, a scanning unit 56, a FAX unit 58, a network interface 60, and the like. The control unit 12 includes a CPU 14, a ROM 16, a RAM 30, an NVRAM 40, and the like.

  The CPU 14 executes various processes according to programs stored in the ROM 16. The processing executed by the CPU 14 will be described in detail later. The RAM 30 is a volatile memory, and is a storage area for storing various types of data generated in the process of executing processing according to the basic function program 18. The ROM 16 stores a basic function program 18 for controlling basic operations of the multi-function device 10. The ROM 16 stores various button data. Examples of button data include character data such as hiragana, alphabets, and numbers, and various function data such as space keys and delete. The ROM 16 stores the size (height and width) of the button area.

  The ROM 16 stores a conversion filter table. The conversion filter table is a table in which conversion filter data, correspondence information, and conversion information are stored. A conversion filter table is prepared for each button data.

  As an example, FIG. 9 shows a conversion filter table TB1b for button data related to the button data “D”. Conversion filter data F1b to F5b are stored in the conversion filter table TB1b. The conversion filter data F1b is data for converting between uppercase and lowercase letters. The conversion filter data F2b is data for converting between bold and thin characters. The conversion filter data F3b is data for converting an italic character. The conversion filter data F4b is data for converting between underline characters. The conversion filter data F5b is data for performing color change conversion.

  The conversion filter table TB1b stores button data B1b to B10b. The button data B1b to B10b are data that can be converted to each other using the conversion filter data F1b to F5b.

  The conversion filter table TB1b stores correspondence information indicating the correspondence between the button data B1b to B10b and the conversion filter data F1b to F5b. For example, the correspondence information of the button data B1b “D” is the conversion filter data F1b to F5b.

  The conversion filter table TB1b stores conversion information indicating the correspondence between the conversion filter data F1b to F5b and the converted button data. For example, conversion information is stored that, when the conversion filter data F1b is applied to the button data B6b “d”, the button data B16b “D” is converted.

  The NVRAM 40 is a non-volatile memory and is a storage area for storing various parameters used when the CPU 14 executes processing according to the basic function program 18 and a button table. The NVRAM 40 stores various settings. The setting to be stored includes setting whether or not to newly display a confirmation area (S231), a value for a predetermined time (S233), and whether or not to confirm an input character when the designated point passes through the confirmation area. Setting (S25), setting of whether or not the selected conversion filter data is reflected in the display of the button data in the initial state (S37), and the like. Also, there are settings for the size of the conversion filter area, the display position of the conversion filter area, the adjacent distance between the conversion filter area and the button area, and the like. These settings may be set in advance by the user.

  Various information such as the conversion filter table stored in the ROM 16 or the NVRAM 40 may be stored in an external storage device. Various kinds of information may be read out from the external storage device and temporarily stored in the RAM 30, and then various kinds of processing may be performed. Examples of the external storage device include a memory card and an external hard disk.

  The network interface 60 is connected to a LAN line. The multi-function device 10 can communicate with an externally connected personal computer and can access the Internet.

  The data input operation performed in the first embodiment will be described with reference to the flowcharts of FIGS. As an example, an operation of inputting uppercase “D” and converting it to lowercase “d” in the first conversion will be described. Further, an operation for converting the lowercase letter “d” to the lowercase letter “d” underlined in the second conversion will be described. Further, a case will be described in which the setting is made so that the input character is confirmed when the designated point passes through the confirmed region (S25: YES). In addition, a case will be described in which the setting for newly displaying the confirmed area is set (S231: YES). Further, a case will be described in which the selected conversion filter data is set to reflect the initial display of button data (S37: YES).

  In S <b> 9, the CPU 14 defines a plurality of button areas on the display panel 50. Then, the button data in the initial state before conversion is displayed in each button area. FIG. 8 shows a display example of the button area on the display panel 50 when alphabetic characters are used.

  In S11, the CPU 14 determines whether or not the display panel 50 is touched. If it is determined that the touch has not been made (S11: NO), the process returns to S11 to be in a standby state. And when it is judged that it was touched (S11: YES), it progresses to S13. In S <b> 13, the CPU 14 acquires the designated coordinates of the designated point touched by the user and stores it in the RAM 30.

  In S15, the CPU 14 determines whether or not the button area is touched. This determination is performed by comparing the coordinates for determining the button area with the instruction coordinates to determine whether the instruction coordinates are located in any button area. When it is determined that the button area is not touched (S15: NO), the process returns to S11 and is in a standby state. If it is determined that the button area has been touched (S15: YES), the process proceeds to S16.

  In S <b> 16, the CPU 14 reads out button data of the selection button area from the ROM 16. The selection button area is a button area selected by the user. For example, when the button area BA11b in FIG. 8 is touched and selected, the button data “D” is acquired from the ROM 16.

In S <b> 17, the CPU 14 calls a conversion filter table related to the selection button area from the ROM 16. Then, conversion filter data corresponding to the button data in the selection button area is specified based on the correspondence information.
In the example of the present embodiment, as shown in FIG. 9, the conversion filter table TB1b related to the button area BA11b is called. Then, conversion filter data F1b and F5b corresponding to the button data B1b are specified from the correspondence information of the button data B1b (“D”).

  In S19, the CPU 14 performs a button area movement process. The contents of the button area moving process will be described with reference to the flowchart of FIG. In S211, the CPU 14 acquires the coordinates of the selection button area. Further, the size of the selection button area is acquired. In the example of the present embodiment, the coordinates of the selection button area BA11b (“D”) are acquired. Further, the size (height and width) of the selection button area BA11b is acquired from the ROM 16.

  In S213, the CPU 14 acquires the number of conversion filters using the correspondence information. In the explanation example of this embodiment, the number of conversion filters = 5 (conversion filter data F1b to F5b) is acquired from the correspondence information of the button data B1b (“D”) in the conversion filter table TB1b. Further, information about the size of the conversion filter area, the adjacent distance between the conversion filter area and the button area, and the display position of the conversion filter area is acquired from the NVRAM 40. In the example of the present embodiment, a case where the width β of the conversion filter region and the adjacent distance γ are acquired will be described. A case will be described in which the display position of the conversion filter area is a position on the circumference centered on the button area.

  In S215, the CPU 14 sets the center of the conversion filter region at the position of the button distance α from the outer periphery of the selection button region. The present embodiment will be described with reference to FIG. FIG. 10 is an enlarged view of the vicinity of the selection button area BA11b (“D”). Button areas BA12b to BA19b are displayed around the button area BA11b. Then, center points CP1b to CP5b are set at positions on the circumference with the selection button area BA11b as the center, with a button distance α from the outer periphery of the selection button area BA11.

  In S217, the CPU 14 calculates the separation distance MD. The separation distance MD is a distance between the selection button area and a button area positioned around the selection button area. In the example of the present embodiment, the separation distance MD is obtained by the sum of the button distance α, the half value of the filter region width β, and the adjacent distance γ.

In S219, the CPU 14 moves the button area located around the selection button area so that the distance between the selection button area and the button area located around the selection button area is the separation distance MD. In the example of this embodiment, as shown in FIG. 11, the button areas BA12b to BA18b move radially around the selection button area BA11b. Further, as the button areas BA12b to BA19b are moved, all the button areas (FIG. 8) displayed on the display panel 50 are also moved. In the present embodiment, for simplification of description, the movement of the button area near the selection button area BA11b will be described below.
When the button area movement process (S19) ends, the process proceeds to S21.

  In S21, the CPU 14 displays a conversion filter area around the selection button area. There may be a plurality of conversion filter regions. Corresponding conversion filter data is displayed in the conversion filter area. In the example of this embodiment, as shown in FIG. 11, conversion filter areas FA11b to FA15b are displayed. Then, conversion filter data F1b to F5b are displayed in the conversion filter areas FA11b to FA15b.

  In S23, the CPU 14 performs a fixed area display process. The contents of the fixed area display process will be described with reference to the flowchart of FIG. In S231, the CPU 14 reads out from the NVRAM 40 and determines whether or not the setting area is set to be newly displayed. If it is not set to be newly displayed (S231: NO), the flow is terminated, and if it is set to be newly displayed (S231: YES), the process proceeds to S233. In the explanation example of the present embodiment, a case where the setting is newly displayed has been explained, and thus the process proceeds to S233.

  In S233, the CPU 14 determines whether or not the designated coordinates exist in the button area or the conversion filter area for a predetermined time. If it does not exist for a predetermined time (S233: NO), it is determined that the user has performed a cancel operation (an operation that does not confirm the input character), and the flow ends without displaying the confirmed area. On the other hand, if it has existed for a predetermined time (S233: YES), it is determined that the confirmation operation has been performed by the user and the process proceeds to S235.

  In S235, the CPU 14 acquires the coordinates of the button area or conversion filter area where the designated coordinates are located. In S237, the CPU 14 sets the center of the fixed region at a position of the button distance α from the outer periphery of the button region or the conversion filter region where the designated coordinates are located. In the example of the present embodiment, as shown in FIG. 12, the center point CP6b is set at the position of the button distance α from the lower side of the selection button area BA11.

  In S238, the CPU 14 calculates the separation distance MD. Then, the other button areas are moved so that the distance between the button area or the conversion filter area where the designated coordinates are located and the other button area is the separation distance MD. Since the detailed operation is the same as the button area movement process (S19) described above, the description thereof is omitted here. In the example of the present embodiment, as shown in FIG. 13, the button area BA19b moves downward.

  In S239, the CPU 14 displays a fixed area. In the example of the present embodiment, as shown in FIG. 13, a fixed area DA11b is displayed. At this time, the conversion filter areas FA11b to FA15b do not exist on the straight path connecting the selection button area BA11b and the confirmation area DA11b. Therefore, the confirmation operation can be performed by sliding the finger to the confirmation area DA11b while keeping the finger in contact with the selection button area BA11b. Thereby, since an input process can be performed without separating the fingertip from the display panel 50, the convenience for the user can be improved.

  In the example of the present embodiment, as shown in FIG. 13, the button area BA11b has a circular shape. Further, the conversion filter areas FA11b to FA15b and the fixed area DA11b are arranged on the circumference of the button distance α from the center of the button area BA11b. Thereby, the distances from the button area BA11b to the conversion filter areas FA11b to FA15 and the fixed area DA11b can be made equal.

  When the confirmation area display process (S23) ends, the process proceeds to S25 (FIG. 3). In S <b> 25, the CPU 14 reads from the NVRAM 40 whether or not the input character is set to be confirmed by passing the designated point through the designated point.

  If it is not set to be confirmed by passing through the confirmed area (S25: NO), the process proceeds to S29. In S <b> 29, the CPU 14 determines whether or not the condition that the designated coordinates are located within the determined area is satisfied. When it is determined that the condition is satisfied (S29: YES), the process proceeds to S31 and input processing is performed. On the other hand, when it is determined that the condition is not satisfied (S29: NO), the process proceeds to S110 (FIG. 4), and a conversion process is performed.

  On the other hand, in S25, when it is set to be confirmed by passing through the confirmed area (S25: YES), the process proceeds to S27. In S <b> 27, the CPU 14 determines whether or not a condition that the designated coordinates pass through the fixed area is satisfied. When it is determined that the condition is satisfied (S27: YES), the process proceeds to S31 and input processing is performed. On the other hand, when it is determined that the condition is not satisfied (S27: NO), the process proceeds to S110 (FIG. 4), and a conversion process is performed.

  In the explanation example of the present embodiment, the case where the setting is confirmed by passing through the confirmed area (S25: YES) is described, and the process proceeds to S27. Further, since the case of performing the conversion process (S27: NO) has been described, the process proceeds to S110 (FIG. 4).

  The conversion process will be described using the flow of FIG. In the flow of FIG. 4, conversion processing is performed using the selected conversion filter. In S110, the CPU 14 determines whether or not the first conversion filter region has been selected. If it is selected (S110: YES), the process proceeds to S111. If it is not selected (S110: NO), the process proceeds to S130. In S130, the CPU 14 determines whether or not the second conversion filter region has been selected. If it is selected (S130: YES), the process proceeds to S111. If it is not selected (S130: NO), the process proceeds to S140. In S140, the CPU 14 determines whether or not the third conversion filter region has been selected. If it is selected (S140: YES), the process proceeds to S111. If it is not selected (S140: NO), the process proceeds to S150. In S150, the CPU 14 determines whether or not the fourth conversion filter region has been selected. If it is selected (S150: YES), the process proceeds to S111. If it is not selected (S150: NO), the process proceeds to S160. In S160, the CPU 14 determines whether or not the fifth conversion filter region has been selected. If it is selected (S160: YES), the process proceeds to S111. If it is not selected (S160: NO), the process proceeds to S171.

  In addition, although FIG. 4 demonstrated the case where the five determination steps of S110, S130, S140, S150, and S160 were prepared, it is not restricted to this form. The number of determination steps is increased or decreased according to the number of conversion filter areas to be displayed. For example, when three conversion filter areas are displayed around the button area, three determination steps are prepared for each of the three conversion filter areas.

  In the example of the present embodiment (FIG. 13), five conversion filter areas FA11b to FA15b are displayed. A case where the point indicated by the user's finger moves as indicated by the arrow Y11 and passes through the conversion filter area FA11b will be described. In this case, the first conversion filter area FA11b is selected (S110: YES), and the process proceeds to S111 (FIG. 5).

  The conversion process in S111 will be described using the flow of FIG. In S112, the button data after the conversion by the selected conversion filter data is specified based on the conversion information. In the example of the present embodiment, the conversion filter data F1b (uppercase / lowercase conversion) in the conversion filter area FA11b is selected. Therefore, in the conversion filter table TB1b shown in FIG. 9, the button data B11b “d” is specified as a result of converting the button data B1b (“D”) with the conversion filter data F1b.

  In S113, the CPU 14 newly displays a button area at a position based on the designated coordinates in the conversion filter area. Then, the converted button data is displayed in a new button area. Also, the conversion filter area is deleted. In the example of the present embodiment, when a finger passes through the conversion filter area FA11b as indicated by an arrow Y11 in FIG. 13, a button area BA21b is displayed at the position of the fingertip as shown in FIG. Then, the converted button data “d” is displayed in the button area BA21b. Thereby, since the distance which a user moves a finger | toe becomes short, a user's convenience can be improved.

  In S115, the CPU 14 calls a conversion filter table related to the converted button data. Then, conversion filter data corresponding to the converted button data is specified based on the correspondence information. In the example of the present embodiment, as shown in FIG. 9, the conversion filter table TB1b related to the converted button data B6b (“d”) is called. Then, conversion filter data F1b to F5b corresponding to the button data B6b are specified from the correspondence information of the button data B4.

  In S117, the CPU 14 performs a button area movement process. Since the detailed operation is the same as that of S19 described above, the description thereof is omitted here. In the example of this embodiment, as shown in FIG. 14, the button areas BA11b to BA14b, BA16b, BA18b move.

  In S119, the CPU 14 newly displays a conversion filter area around the button area. Then, the conversion filter data is displayed in the conversion filter area. In the example of this embodiment, as shown in FIG. 14, conversion filter areas FA21b to FA25b are displayed around the button area BA21. Then, conversion filter data F1b to F5b are displayed in the conversion filter areas FA21b to FA25b.

  The newly displayed conversion filter data includes conversion filter data for returning the converted button data to the button data before conversion. In the example of the present embodiment, in FIG. 14, a conversion filter area FA21b (uppercase / lowercase conversion) for returning the converted button data B6b (“d”) to the button data B1b (“D”) before conversion. ))It is included. Thus, for example, even if an erroneous conversion is performed in the first conversion operation, the conversion operation can be returned to the state before the conversion by the second conversion operation. Can increase the sex.

  In S121, the CPU 14 performs a fixed area display process. Since the detailed operation is the same as that of S23 described above, the description thereof is omitted here. In the example of the present embodiment, as shown in FIG. 14, a fixed area DA21b is displayed. Then, the process returns to S25 (FIG. 3).

  In the explanation example of the present embodiment, the case where the setting is confirmed by passing through the confirmed area (S25: YES) is described, and the process proceeds to S27. Further, in the description example of this embodiment, a case will be described in which the point indicated by the user's finger moves as shown by an arrow Y12 in FIG. 14 and passes through the conversion filter area FA24b. In this case, since the fourth conversion filter area FA24b is selected (S150: YES), the process proceeds to S111 (FIG. 5).

  The conversion filter area FA24b corresponds to the conversion filter data F4b (underline). Therefore, in S112, button data B46b ("d" underlined) is specified as a result of converting button data B6b ("d") with conversion filter data F5 in conversion filter table TB1b shown in FIG. .

  In S113, as shown in FIG. 15, the button area BA31b is displayed. Then, the converted button data B46b (underlined “d”) is displayed in the button area BA31b. In S115, conversion filter data F1b to F5b corresponding to the button data B9b are specified from the correspondence information of the button data B9b (“d” underlined).

  In S117, the CPU 14 performs a button area movement process. In the example of this embodiment, as shown in FIG. 15, the button areas BA12b to BA14b, BA16b, BA11b, and BA18b move.

  In S119, as shown in FIG. 15, the CPU 14 displays conversion filter areas FA31b to FA35b and a fixed area DA31b around the button area BA31b. The conversion filter data F1b to F5b are displayed in the conversion filter areas FA31b to FA35b. Then, the process returns to S25 (FIG. 3).

  Since the case where the setting is confirmed by passing through the confirmed area (S25: YES) is described, the process proceeds to S27. In the example of the present embodiment, the second conversion operation has been completed. Therefore, in FIG. 15, the case where the indicated point is moved as indicated by the arrow Y13 and passes through the fixed area DA31b (S27: YES) will be described. In this case, it progresses to S31 and an input process is performed.

  In S31, the CPU 14 determines the converted button data as input data. In S33, the CPU 14 deletes the conversion filter area and the fixed area. In the example of the present embodiment, the conversion filter areas FA31b to FA35b and the fixed area DA31b are deleted in FIG. In S35, the CPU 14 returns the position of the button area to the initial state. In the explanation example of this embodiment, as shown in FIG. 10, the arrangement of the button areas is returned to the initial state.

  In S37, the CPU 14 reads from the NVRAM 40 whether or not the selected conversion filter data is set to be reflected in the display of the button data in the initial state. If the setting is to be reflected (S37: YES), the process proceeds to S39, and the conversion filter data is reflected in the button data. On the other hand, if the setting is not reflected (S37: NO), the flow ends.

  In the explanation example of the present embodiment, a case is described in which the setting that reflects the selected conversion filter data is set (S37: YES). Also, conversion filter data F1b (conversion to lower case) is selected. Therefore, the conversion filter data F1b is reflected in the button data (upper case) in the initial state in FIG. 8, and the button arrangement in FIG. Thus, once the conversion filter data is used, the content of the conversion filter data is automatically reflected from the input of the next character. Therefore, the conversion operation can be reduced when it is necessary to continuously input the same type of characters, such as when inputting lowercase words.

  In addition, the operation when neither the conversion filter region nor the fixed region is selected (FIG. 4, S110: NO, S130: NO, S140: NO, S150: NO, S160: NO) will be described. For example, in the display of FIG. 15, none of the conversion filter areas FA31b to FA35b and the fixed area DA31b is selected. In this case, the process proceeds to S171.

  In S <b> 171, the CPU 14 determines whether or not the user has lifted his / her finger from the display panel 50. If it is determined that they are not separated (S171: NO), the process returns to S25 (FIG. 3). If it is determined that they are separated (S171: YES), the process proceeds to S173.

  In S173, the CPU 14 deletes the conversion filter area. In S175, the CPU 14 erases the confirmed area. In the example of the present embodiment, the conversion filter areas FA31b to FA35b and the fixed area DA31b are deleted in FIG.

  In S177, the CPU 14 returns the position of the button area to the initial state. In the explanation example of this embodiment, as shown in FIG. 10, the arrangement of the button areas is returned to the initial state. Then, the process returns to S11 (FIG. 2) and the next input operation is accepted.

The effect of the input device according to the first embodiment will be described. In the input device according to the first embodiment, a plurality of types of conversion filter data can be applied to one button data, so that complicated conversion contents can be implemented.
For example, even when the button data is uppercase (for example, “D”), the conversion filter data is applied twice, so that it is possible to convert the underlined lowercase letter (for example, “d”). In addition, since the conversion filter area for performing the conversion operation is displayed around the selection button area, the conversion operation can be easily performed. As described above, since it is possible to perform complicated conversion contents with a simple operation, it is possible to improve user convenience.

  Further, the user can perform input processing by passing the fingertip through the fixed area. Thereby, first, it is possible to prevent the input process from being performed even when the confirmed area is accidentally touched. Therefore, it is possible to perform input processing more reliably. Second, the input process and the cancel operation can be clearly distinguished. For example, after touching the button area, a cancel operation can be performed by releasing the fingertip, and an input process can be performed by passing the fingertip through the fixed area. Therefore, user convenience can be improved.

  A second embodiment will be described. The second embodiment is an embodiment where hiragana characters are used for the button data.

  As an example, FIG. 17 shows a conversion filter table TB1 for button data related to the button data “HI”. Conversion filter data F1 to F5 are stored in the conversion filter table TB1. The conversion filter data F1 is data for conversion into hiragana characters. The conversion filter data F2 is data for conversion into katakana characters. The conversion filter data F3 is data for converting between uppercase and lowercase letters. The conversion filter data F4 is data for converting between full-width characters and half-width characters. The conversion filter data F5 is data for converting muddy sound or semi-voiced sound into characters.

  In addition, button data B1 to B6 are stored in the conversion filter table TB1. The button data B1 to B6 are data that can be converted to each other using the conversion filter data F1 to F5.

  The conversion filter table TB1 stores correspondence information indicating correspondence between the button data B1 to B6 and the conversion filter data F1 to F5. For example, the correspondence information of the button data B1 “HI” is the conversion filter data F2 and F5. Further, for example, the correspondence information of the button data B4 “H” is the conversion filter data F1, F4, and F5.

  The conversion filter table TB1 stores conversion information indicating the correspondence between the conversion filter data F1 to F5 and the converted button data. For example, conversion information indicating that when the conversion filter data F1 is applied to the button data B4 “hi”, the button data B14 “hi” is converted is stored.

  FIG. 18 shows a conversion filter table TB1a for button data related to “a” in hiragana. The conversion filter table TB1a in FIG. 18 is a table in which the conversion filter data F3 exists but the conversion filter data F5 does not exist as compared to the conversion filter table TB1 in FIG. In this way, the stored conversion filters are different for each character.

  The data input operation performed in the second embodiment will be described with reference to the flowcharts of FIGS. As an example, an operation of inputting a hiragana character “hi” and converting it to a katakana character “hi” in the first conversion will be described. Further, an operation for converting the katakana character “hi” to the cloudy katakana character “bi” in the second conversion will be described. Further, a case will be described in which the setting is made so that the input character is confirmed when the designated point passes through the confirmed region (S25: YES). In addition, a case will be described in which the setting for newly displaying the confirmed area is set (S231: YES). Further, a case will be described in which the selected conversion filter data is set to reflect the initial display of button data (S37: YES).

  In S <b> 9, the CPU 14 defines a plurality of button areas on the display panel 50. Then, the button data in the initial state before conversion is displayed in each button area. FIG. 16 shows a display example of the button area on the display panel 50 when hiragana characters are used.

  In S11, the CPU 14 determines whether or not the display panel 50 is touched. If it is determined that the touch has not been made (S11: NO), the process returns to S11 to be in a standby state. And when it is judged that it was touched (S11: YES), it progresses to S13. In S <b> 13, the CPU 14 acquires the designated coordinates of the designated point touched by the user and stores it in the RAM 30.

  In S15, the CPU 14 determines whether or not the button area is touched. This determination is performed by comparing the coordinates for determining the button area with the instruction coordinates to determine whether the instruction coordinates are located in any button area. When it is determined that the button area is not touched (S15: NO), the process returns to S11 and is in a standby state. If it is determined that the button area has been touched (S15: YES), the process proceeds to S16.

  In S <b> 16, the CPU 14 reads out button data of the selection button area from the ROM 16. The selection button area is a button area selected by the user. As an example, when the button area BA11 in FIG. 16 is touched and selected, the button data “HI” is acquired from the ROM 16.

  In S <b> 17, the CPU 14 calls a conversion filter table related to the selection button area from the ROM 16. Then, conversion filter data corresponding to the button data in the selection button area is specified based on the correspondence information. In the example of the present embodiment, as shown in FIG. 17, the conversion filter table TB1 related to the button area BA11 is called. Then, conversion filter data F2 and F5 corresponding to the button data B1 are specified from the correspondence information of the button data B1 (“HI”).

  In S19, the CPU 14 performs a button area movement process. The contents of the button area moving process will be described with reference to the flowchart of FIG. In S211, the CPU 14 acquires the coordinates of the selection button area. Further, the size of the selection button area is acquired. In the example of the present embodiment, the coordinates of the selection button area BA11 (“HI”) are acquired. Further, the size (height and width) of the selection button area BA11 is acquired from the ROM 16.

  In S213, the CPU 14 acquires the number of conversion filters using the correspondence information. In the description example of the present embodiment, the number of conversion filters = 2 (conversion filter data F2 and F5) is acquired from the correspondence information of the button data B1 (“Hi”) in the conversion filter table TB1. Further, information about the size of the conversion filter area, the adjacent distance between the conversion filter area and the button area, and the display position of the conversion filter area is acquired from the NVRAM 40. In the example of the present embodiment, a case where the width β of the conversion filter region and the adjacent distance γ are acquired will be described. A case will be described in which the display position of the conversion filter area is set to the left and right positions of the button area.

  In S215, the CPU 14 sets the center of the conversion filter region at the position of the button distance α from the outer periphery of the selection button region. The present embodiment will be described with reference to FIG. FIG. 19 is an enlarged view of the vicinity of the selection button area BA11 (“HI”). Button areas BA12 to BA19 are displayed around the button area BA11. Then, center points CP1 and CP2 are set at the left and right positions of the selection button area BA11 with the button distance α from the outer periphery of the selection button area BA11.

  In S217, the CPU 14 calculates the separation distance MD. The separation distance MD is a distance between the selection button area and a button area positioned around the selection button area. In the example of the present embodiment, the separation distance MD is obtained by the sum of the button distance α, the half value of the filter region width β, and the adjacent distance γ.

  In S219, the CPU 14 moves the button area located around the selection button area so that the distance between the selection button area and the button area located around the selection button area is the separation distance MD. In the example of the present embodiment, as shown in FIG. 20, the button areas BA12 to BA14 move to the left side, and the button areas BA15 to BA17 move to the right side. Further, as the button areas BA12 to BA19 move, all the button areas (FIG. 16) displayed on the display panel 50 also move. In this embodiment, for simplification of description, the movement of the button area near the selection button area BA11 will be described below. When the button area movement process (S19) ends, the process proceeds to S21.

  In S21, the CPU 14 displays a conversion filter area around the selection button area. There may be a plurality of conversion filter regions. Corresponding conversion filter data is displayed in the conversion filter area. In the example of the present embodiment, conversion filter areas FA11 and FA12 are displayed as shown in FIG. Then, conversion filter data F2 (conversion to katakana) and F5 (conversion of muddy / semi-voiced sound) are displayed in the conversion filter areas FA11 and FA12.

  In S23, the CPU 14 performs a fixed area display process. The contents of the fixed area display process will be described with reference to the flowchart of FIG. In S231, the CPU 14 reads out from the NVRAM 40 and determines whether or not the setting area is set to be newly displayed. If it is not set to be newly displayed (S231: NO), the flow is terminated, and if it is set to be newly displayed (S231: YES), the process proceeds to S233. In the explanation example of the present embodiment, a case where the setting is newly displayed has been explained, and thus the process proceeds to S233.

  In S233, the CPU 14 determines whether or not the designated coordinates exist in the button area or the conversion filter area for a predetermined time. If it does not exist for a predetermined time (S233: NO), it is determined that the user has performed a cancel operation (an operation that does not confirm the input character), and the flow ends without displaying the confirmed area. On the other hand, if it has existed for a predetermined time (S233: YES), it is determined that the confirmation operation has been performed by the user and the process proceeds to S235.

  In S235, the CPU 14 acquires the coordinates of the button area or conversion filter area where the designated coordinates are located. In S237, the CPU 14 sets the center of the fixed region at a position of the button distance α from the outer periphery of the button region or the conversion filter region where the designated coordinates are located. In the example of the present embodiment, as shown in FIG. 21, the center point CP3 is set at the position of the button distance α from the lower side of the selection button area BA11.

  In S238, the CPU 14 calculates the separation distance MD. Then, the other button areas are moved so that the distance between the button area or the conversion filter area where the designated coordinates are located and the other button area is the separation distance MD. Since the detailed operation is the same as the button area movement process (S19) described above, the description thereof is omitted here. In the example of this embodiment, as shown in FIG. 22, the button areas BA14, BA19, BA17 move downward.

  In S239, the CPU 14 displays a fixed area. In the example of the present embodiment, as shown in FIG. 22, the fixed area DA11 is displayed. At this time, the conversion filter areas FA11 and FA12 do not exist on the straight path connecting the selection button area BA11 and the confirmation area DA11. Therefore, the confirmation operation can be performed by sliding the finger to the confirmation area DA11 while maintaining the state in which the finger is in contact with the selection button area BA11. Thereby, since an input process can be performed without separating the fingertip from the display panel 50, the convenience for the user can be improved.

  When the confirmation area display process (S23) ends, the process proceeds to S25 (FIG. 3). In S <b> 25, the CPU 14 reads from the NVRAM 40 whether or not the input character is set to be confirmed by passing the designated point through the designated point.

  If it is not set to be confirmed by passing through the confirmed area (S25: NO), the process proceeds to S29. In S <b> 29, the CPU 14 determines whether or not the condition that the designated coordinates are located within the determined area is satisfied. When it is determined that the condition is satisfied (S29: YES), the process proceeds to S31 and input processing is performed. On the other hand, when it is determined that the condition is not satisfied (S29: NO), the process proceeds to S110 (FIG. 4), and a conversion process is performed.

  On the other hand, in S25, when it is set to be confirmed by passing through the confirmed area (S25: YES), the process proceeds to S27. In S <b> 27, the CPU 14 determines whether or not a condition that the designated coordinates pass through the fixed area is satisfied. When it is determined that the condition is satisfied (S27: YES), the process proceeds to S31 and input processing is performed. On the other hand, when it is determined that the condition is not satisfied (S27: NO), the process proceeds to S110 (FIG. 4), and a conversion process is performed.

  In the explanation example of the present embodiment, the case where the setting is confirmed by passing through the confirmed area (S25: YES) is described, and the process proceeds to S27. Further, since the case of performing the conversion process (S27: NO) has been described, the process proceeds to S110 (FIG. 4).

  The conversion process will be described using the flow of FIG. In the flow of FIG. 4, conversion processing is performed using the selected conversion filter. In S110, the CPU 14 determines whether or not the first conversion filter region has been selected. If it is selected (S110: YES), the process proceeds to S111. If it is not selected (S110: NO), the process proceeds to S130. In S130, the CPU 14 determines whether or not the second conversion filter region has been selected. If it is selected (S130: YES), the process proceeds to S111. If it is not selected (S130: NO), the process proceeds to S140. In S140, the CPU 14 determines whether or not the third conversion filter region has been selected. If it is selected (S140: YES), the process proceeds to S111. If it is not selected (S140: NO), the process proceeds to S150. In S150, the CPU 14 determines whether or not the fourth conversion filter region has been selected. If it is selected (S150: YES), the process proceeds to S111. If it is not selected (S150: NO), the process proceeds to S160. In S160, the CPU 14 determines whether or not the fifth conversion filter region has been selected. If it is selected (S160: YES), the process proceeds to S111. If it is not selected (S160: NO), the process proceeds to S171.

  In addition, although FIG. 4 demonstrated the case where the five determination steps of S110, S130, S140, S150, and S160 were prepared, it is not restricted to this form. The number of determination steps is increased or decreased according to the number of conversion filter areas to be displayed. For example, when three conversion filter areas are displayed around the button area, three determination steps are prepared for each of the three conversion filter areas.

  In the example of the present embodiment (FIG. 22), a first conversion filter area FA11 and a second conversion filter area FA12 are displayed. A case where the indication point by the user's finger moves as indicated by the arrow Y1 and passes through the conversion filter area FA11 will be described. In this case, the first conversion filter area FA11 is selected (S110: YES), and the process proceeds to S111 (FIG. 5).

  The conversion process in S111 will be described using the flow of FIG. In S112, the button data after the conversion by the selected conversion filter data is specified based on the conversion information. In the example of the present embodiment, the conversion filter data F2 (conversion to katakana) in the conversion filter area FA11 is selected. Therefore, in the conversion filter table TB1 shown in FIG. 17, the button data B51 “H” is specified as a result of converting the button data B1 (“HI”) with the conversion filter data F2.

  In S113, the CPU 14 newly displays a button area at a position based on the designated coordinates in the conversion filter area. Then, the converted button data is displayed in a new button area. Also, the conversion filter area is deleted. In the example of this embodiment, when a finger passes through the conversion filter area FA11 as indicated by the arrow Y1 in FIG. 22, the button area BA21 is displayed at the position of the fingertip as shown in FIG. Then, the converted button data “H” is displayed in the button area BA21. Thereby, since the distance which a user moves a finger | toe becomes short, a user's convenience can be improved.

  In S115, the CPU 14 calls a conversion filter table related to the converted button data. Then, conversion filter data corresponding to the converted button data is specified based on the correspondence information. In the example of the present embodiment, as shown in FIG. 17, the conversion filter table TB1 related to the converted button data B4 (“H”) is called. Then, conversion filter data F1, F4, and F5 corresponding to the button data B4 are specified from the correspondence information of the button data B4.

  In S117, the CPU 14 performs a button area movement process. Since the detailed operation is the same as that of S19 described above, the description thereof is omitted here. In the example of this embodiment, as shown in FIG. 23, the button areas BA12, BA18, BA11, BA16 move.

  In S119, the CPU 14 newly displays a conversion filter area around the button area. Then, the conversion filter data is displayed in the conversion filter area. In the example of this embodiment, as shown in FIG. 23, conversion filter areas FA21 to FA23 are displayed around the button area BA21. In the conversion filter areas FA21 to FA23, conversion filter data F1 (conversion to hiragana), F5 (conversion of muddy / semi-voiced sound) and F4 (conversion of full-width / half-width) are displayed.

  The newly displayed conversion filter data includes conversion filter data for returning the converted button data to the button data before conversion. In the explanation example of the present embodiment, in FIG. 23, the conversion filter area FA21 (conversion to hiragana) for returning the converted button data B4 ("HI") to the button data B1 ("HI") before conversion. It is included. Thus, for example, even if an erroneous conversion is performed in the first conversion operation, the conversion operation can be returned to the state before the conversion by the second conversion operation. Can increase the sex.

  In S121, the CPU 14 performs a fixed area display process. Since the detailed operation is the same as that of S23 described above, the description thereof is omitted here. In the example of the present embodiment, as shown in FIG. 23, a fixed area DA21 is displayed. Then, the process returns to S25 (FIG. 3).

  In the explanation example of the present embodiment, the case where the setting is confirmed by passing through the confirmed area (S25: YES) is described, and the process proceeds to S27. Further, in the description example of the present embodiment, a case will be described in which the point indicated by the user's finger moves as shown by an arrow Y2 and passes through the conversion filter area FA22 in FIG. In this case, since the third conversion filter area FA22 is selected (S140: YES), the process proceeds to S111 (FIG. 5).

  The conversion filter area FA22 corresponds to conversion filter data F5 (conversion of muddy / semi-voiced sound). Therefore, in S112, button data B54 ("B") is specified as a result of converting button data B4 ("HI") with conversion filter data F5 in the conversion filter table TB1 shown in FIG.

  In S113, as shown in FIG. 24, the button area BA31 is displayed. Then, the converted button data B54 ("Bi") is displayed in the button area BA31. In S115, conversion filter data F1, F4, and F5 corresponding to the button data B5 are specified from the correspondence information of the button data B5 (“Bi”).

  In S117, the CPU 14 performs a button area movement process. In the explanation example of this embodiment, as shown in FIG. 24, the button areas BA12 to BA14, BA16, BA11, and BA18 move.

  In S119, the CPU 14 displays conversion filter areas FA31 to FA33 and a fixed area DA31 around the button area BA31 as shown in FIG. Then, the conversion filter data F1, F5 and F4 are displayed in the conversion filter areas FA31 to FA33. Then, the process returns to S25 (FIG. 3).

  Since the case where the setting is confirmed by passing through the confirmed area (S25: YES) is described, the process proceeds to S27. In the example of the present embodiment, the second conversion operation has been completed. Therefore, in FIG. 24, the case where the designated point is moved as indicated by the arrow Y3 and passed through the fixed area DA31 (S27: YES) will be described. In this case, it progresses to S31 and an input process is performed.

  In S31, the CPU 14 determines the converted button data as input data. In S33, the CPU 14 deletes the conversion filter area and the fixed area. In the example of the present embodiment, the conversion filter areas FA31 to FA33 and the fixed area DA31 are deleted in FIG. In S35, the CPU 14 returns the position of the button area to the initial state. In the example of this embodiment, as shown in FIG. 19, the arrangement of the button areas is returned to the initial state.

  In S37, the CPU 14 reads from the NVRAM 40 whether or not the selected conversion filter data is set to be reflected in the display of the button data in the initial state. If the setting is to be reflected (S37: YES), the process proceeds to S39, and the conversion filter data is reflected in the button data. On the other hand, if the setting is not reflected (S37: NO), the flow ends.

  In the explanation example of the present embodiment, a case is described in which the setting that reflects the selected conversion filter data is set (S37: YES). Also, conversion filter data F2 (conversion to katakana) is selected. Therefore, the conversion filter data F2 is reflected in the button data (Hiragana characters) in the initial state of FIG. 16, and all the button arrays in FIG. Thus, once the conversion filter data is used, the content of the conversion filter data is automatically reflected from the input of the next character. Therefore, the conversion operation can be reduced when it is necessary to continuously input the same type of characters, such as when inputting katakana characters.

  In addition, the operation when neither the conversion filter region nor the fixed region is selected (FIG. 4, S110: NO, S130: NO, S140: NO, S150: NO, S160: NO) will be described. For example, in the display of FIG. 24, none of the conversion filter areas FA31 to FA33 and the fixed area DA31 is selected. In this case, the process proceeds to S171.

  In S <b> 171, the CPU 14 determines whether or not the user has lifted his / her finger from the display panel 50. If it is determined that they are not separated (S171: NO), the process returns to S25 (FIG. 3). If it is determined that they are separated (S171: YES), the process proceeds to S173.

  In S173, the CPU 14 deletes the conversion filter area. In S175, the CPU 14 erases the confirmed area. In the example of the present embodiment, the conversion filter areas FA31 to FA33 and the fixed area DA31 are deleted in FIG.

  In S177, the CPU 14 returns the position of the button area to the initial state. In the example of this embodiment, as shown in FIG. 19, the arrangement of the button areas is returned to the initial state. Then, the process returns to S11 (FIG. 2) and the next input operation is accepted.

  The effect of the input device according to the first embodiment will be described. In the input device according to the first embodiment, a plurality of types of conversion filter data can be applied to one button data, so that complicated conversion contents can be implemented. For example, even when the button data is hiragana (for example, “hi”), by applying the conversion filter data twice, it is possible to convert it into muffled kana characters (for example, “bi”). In addition, since the conversion filter area for performing the conversion operation is displayed around the selection button area, the conversion operation can be easily performed. As described above, since it is possible to perform complicated conversion contents with a simple operation, it is possible to improve user convenience.

  Further, the user can perform input processing by passing the fingertip through the fixed area. Thereby, first, it is possible to prevent the input process from being performed even when the confirmed area is accidentally touched. Therefore, it is possible to perform input processing more reliably. Second, the input process and the cancel operation can be clearly distinguished. For example, after touching the button area, a cancel operation can be performed by releasing the fingertip, and an input process can be performed by passing the fingertip through the fixed area. Therefore, user convenience can be improved.

  A third embodiment will be described. The third embodiment is a modification of the method for displaying the fixed area. In the third embodiment, S233a and S235a are used instead of S233 and S235 in the flow of FIG.

  In S233a, the CPU 14 detects that the designated coordinates are detected in the button area or the conversion filter area, and then the designated coordinates are not detected in the button area or the conversion filter area without exiting from the button area or the conversion filter area. It is determined whether the condition is satisfied. If not established (S233a: NO), it is determined that the user has performed a cancel operation (an operation that does not confirm the input character), and the flow ends without displaying the confirmed area. On the other hand, if it is established (S233a: YES), it is determined that the confirmation operation has been performed by the user, and the process proceeds to S235a.

  In S235a, the CPU 14 acquires the coordinates of the position where the designated coordinates are no longer detected. In S237, the CPU 14 sets the center of the fixed region from the position where the designated coordinates are no longer detected to the position of the button distance α. Since the flow after S238 is the same as that of the first embodiment, detailed description thereof is omitted here.

  Thereby, in the example of FIG. 13, when the finger is released from the selection button area BA11b, the confirmation area DA11b is displayed. Accordingly, since the input character is not confirmed by releasing the finger, it becomes easy to reselect another button area (for example, button area BA19b (“C”)).

  Further, since it is necessary to remove the fingertip from the display panel 50 in order to display the confirmed area DA11b, the next selection of the confirmed area DA11b is an operation of touching the fingertip. Therefore, the fingertip moves away from the display panel 50 during the movement between the button area BA11b and the confirmed area DA11b. Then, even if another button area or the like is displayed between the button area BA11b and the confirmed area DA11b, these areas are not touched. Therefore, it is possible to increase the degree of freedom of the button area layout and the like. Become.

  A fourth embodiment will be described. The fourth embodiment is a modification of the determination method of the definite region. In the fourth embodiment, S29a is used instead of S29 in the flow of FIG.

  In S <b> 29 a, the CPU 14 determines whether or not a condition is satisfied that the designated coordinates are detected in the confirmed area and then the designated coordinates are not detected in the confirmed area without exiting from the confirmed area. . If it is determined that the condition is satisfied (S29a: YES), the process proceeds to S31, and if it is determined that the condition is not satisfied (S29a: NO), the process proceeds to S110 (FIG. 4). Since other flows are the same as those in the first embodiment, detailed description thereof is omitted here.

  As a result, in the example of FIG. 15, the input point can be moved by moving the designated point into the confirmed area DA31 as indicated by the arrow Y13a and releasing the fingertip within the confirmed area DA31. Therefore, as shown by the arrow Y13 in FIG. 15, it is possible to perform the input process with fewer operations compared to the case where the input process is performed by passing the fingertip through the fixed area DA31.

  A fifth embodiment will be described. The fifth embodiment is an example of button data input operation. A case where the word “DOG” is input using the button area of FIG. 8 will be described. When the user touches the button area BA11b (“D”) with a fingertip for a predetermined time (S233: YES), the confirmed area is displayed (S239, confirmed area DA11b (FIG. 13)). Then, when the user slides the fingertip while touching the surface of the display panel 50 and passes the fingertip through the confirmed area DA11b, an input process is performed, and the button data “D” is displayed in the confirmed area DA1c.

  Then, while touching the surface of the display panel 50, the fingertip is slid to the next button area BA20b (“O”). When the button area BA20b is touched for a predetermined time, a new confirmation area is displayed around the button area BA20b. Then, when the fingertip passes through the fixed area while touching the surface of the display panel 50, an input process is performed, and the button data “O” is displayed in the fixed area DA1c.

  In the same manner, the next button area BA21b (“G”) is touched for a predetermined time, and input processing is performed. With the above operation, the input of the word “DOG” is completed.

  Thereby, it is possible to select the button data and input the button data without releasing the fingertip from the display panel 50. In other words, it is possible to input characters by a one-stroke operation. When the user presses down a desired button area, if the fingertip is touched from a state away from the display panel 50, there is a possibility that a deviation occurs between the point where the touch is intended and the actual touch point. However, according to the data input device of the present application, since it is not necessary to move the fingertip away from the display panel 50, it is possible to select the button region or the confirmed region while always confirming the touch point. Therefore, since there is no deviation between the point intended to be touched and the actual touch point, it is possible to accurately select the button data and input the button data, thereby improving the convenience for the user. it can.

  A sixth embodiment will be described with reference to FIGS. 26 and 27. FIG. The sixth embodiment is a modification of the button area moving method in S219 (FIG. 6). FIG. 26 shows an initial state of button area arrangement. In FIG. 26, the width of the button area is defined as a width ε, and the distance between the button areas is defined as a distance δ. A button area touched by the user is defined as a selection button area. A button area existing around the selection button area is defined as an adjacent button area. In addition, a button area located adjacent to the selection button area is defined as a first adjacent button area. In addition, a button area located adjacent to the first adjacent button area is defined as a second adjacent button area.

  Hereinafter, the reduction operation of the first adjacent button area BA16b and the second adjacent button area BA32b in the case where the selection button area BA11b is touched will be described. As an example, a case will be described in which the upper limit reduction rate of the adjacent button area is 50 (%). The upper limit reduction rate is an upper limit value of the rate of reducing the width of the adjacent button area. When the selection button area is touched, in S219, a process for setting the distance between the selection button area and the first adjacent button area to the separation distance MD is started. Specifically, the CPU 14 determines whether or not the separation distance MD can be secured by reducing the width of the first adjacent button area. If it is determined that it can be secured, the width of the first adjacent button area is reduced, and the process ends. On the other hand, if it is determined that it cannot be secured, the width of the first adjacent button area is reduced to 50 (%) of the upper limit reduction ratio and then moved outside the range of the separation distance MD. In the example of FIG. 27, the width of the first adjacent button area BA16b is reduced to the upper limit reduction ratio (ε / 2) and then moved to the right side in the figure.

  In addition, when the first adjacent button area is moved, the CPU 14 reduces the width of the second adjacent button area so that the distance between the first adjacent button area and the second adjacent button area becomes the distance δ. . Then, it is determined whether or not the distance δ can be secured. If it is determined that it can be secured, the width of the second adjacent button area is reduced, and the process ends. On the other hand, if it is determined that it cannot be secured, the width of the second adjacent button area is reduced to 50 (%) of the upper limit reduction rate, and then moved outside the range of the distance δ. In the example of FIG. 27, the width of the second adjacent button area BA32b is reduced until the distance δ can be secured.

  Then, the above process is repeated until the distance δ can be secured without moving the adjacent button area. The first adjacent button area BA15b and BA17b to BA19b are also processed in the same manner as the first adjacent button area BA16b. Further, the same processing as that of the second adjacent button area BA32b is performed for the second adjacent button areas BA31b and BA33b.

  Thereby, the movement distance of an adjacent button area | region can be shortened by reducing an adjacent button area | region. Therefore, since the distance to move the finger when the user touches the adjacent button area can be shortened, the convenience for the user can be improved. In addition, by setting the upper limit reduction rate, it is possible to prevent a situation in which the adjacent button area is reduced too much and becomes difficult to touch.

  The technical elements described in this specification or the drawings exhibit technical usefulness alone or in various combinations, and are not limited to the combinations described in the claims at the time of filing. In addition, the technology illustrated in the present specification or the drawings achieves a plurality of objects at the same time, and has technical utility by achieving one of the objects.

  It is also possible to set so that the confirmation area is not newly displayed (S231: NO). In this case, the fixed area is displayed in advance. FIG. 8 and FIG. 16 show examples of forms in which the fixed area is displayed in advance. In FIG. 8, the fixed area DA1c is displayed at the top of the display panel 50. In addition, a boundary line BL1c of the fixed area is displayed. In FIG. 16, the fixed area DA1a is displayed at the top of the display panel 50. In addition, a boundary line BL1 of the fixed area is displayed.

  This will be described with reference to FIG. In this case, in S29, the CPU 14 determines whether or not a condition that the designated coordinates are located in the fixed area DA1c is satisfied. For example, when the user inputs the button data of the button area BA11b (“D”), the button area BA11b is touched, and the finger is kept in contact with the display panel 50 and the boundary line BL1c is passed to the confirmed area DA1c. Move. As a result, it is determined that the condition that the designated coordinates are located within the confirmed area DA1c is satisfied (S29: YES), and the button data “D” is input.

  In S25, it may not be set to be confirmed by passing through the confirmed area. In this case, in S29, the CPU 14 proceeds to 31 when the condition that the designated coordinates are located within the fixed region is satisfied (S29: YES), and the input process is performed. Thus, for example, in the example of FIGS. 13 and 22, it can be assumed that the input process is not performed until the finger is positioned in the fixed area DA11.

  Note that the content of the conversion filter data is not limited to the content shown in the conversion filter tables TB1 to TB1c. For example, the content of the conversion filter data may be a conversion process between characters that are not stuttering and characters that are stuttering. Moreover, the conversion process between the character which is not a prompt sound and the character which is a prompt sound may be sufficient. Moreover, the conversion process between the character which is not a long sound and the character which is a long sound may be sufficient. Moreover, the conversion process between the character without a phonetic symbol (example: umlaut) and the character with a phonetic symbol may be sufficient. Moreover, the conversion process which changes the size (for example, 10 points etc.) of a character may be sufficient.

  In addition, the shape of the button area and the conversion filter area is not limited to a rectangle, and may be an arbitrary shape. In addition, the number of conversion filter areas displayed around the button area can be set to an arbitrary number.

  Further, when the conversion filter data is displayed in the conversion filter area, the conversion contents (lower case, katakana, muddy sound, etc.) of the conversion filter data are displayed. However, the present invention is not limited to this. The button data after conversion by the conversion filter data may be displayed in the conversion filter area. For example, in FIG. 11, “d” obtained by converting the button data “D” in the button area BA11b with the conversion filter data F11b (uppercase / lowercase conversion) may be displayed in the conversion filter area FA11b. Further, the bold character “D” obtained by converting the button data “D” of the button area BA11b with the conversion filter data FA12b (bold / thin conversion) may be displayed in the conversion filter area FA12b. Similarly, the converted button data may be displayed in the conversion filter areas FA13b to FA15b.

  Note that conversion between hiragana characters and alphabetic characters may be included as in the conversion filter table TB1c of FIG. Thereby, even when the hiragana button arrangement of FIG. 16 is used, it is possible to input the alphabet. In addition, when the button arrangement of alphabetical characters in FIG. 8 is used, it becomes possible to input hiragana characters.
