In addition, the second housing 1CB is provided with a microphone 5 that receives sound when the mobile electronic device 1 is in a call.

  The first housing 1CA and the second housing 1CB are connected by a hinge 18. As a result, the first casing 1CA and the second casing 1CB rotate together around the hinge 18 so that they can rotate in a direction away from each other and a direction approaching each other (a direction indicated by an arrow R in FIG. 2). Configured. When the first casing 1CA and the second casing 1CB rotate in a direction away from each other, the portable electronic device 1 opens, and when the first casing 1CA and the second casing 1CB rotate in a direction approaching each other, the portable electronic device 1 opens. Device 1 closes.

  Next, the relationship between the function of the portable electronic device 1 and the control unit will be described. FIG. 3 is a block diagram showing a schematic configuration of functions of the portable electronic device shown in FIG. As shown in FIG. 3, the mobile electronic device 1 includes a main control unit 22, a storage unit 24, a communication unit 26, an operation unit 28, an input data acquisition unit 29, an audio processing unit 30, and a display unit 32. And a display control unit 33.

  The main control unit 22 is a processing unit that centrally controls the overall operation of the mobile electronic device 1, for example, a CPU (Central Processing Unit). That is, the communication unit 26, the display unit, and the like so that various types of processing of the portable electronic device 1 are executed in an appropriate procedure according to the operation of the operation unit 28 and the software stored in the storage unit 24 of the portable electronic device 1. 32 and the like are controlled. The main control unit 22 executes processing based on programs (for example, operating system programs, application programs, etc.) stored in the storage unit 24. The storage unit 24 stores software and data used for processing in the main control unit 22. Specifically, software that performs character conversion processing, software that transmits and receives mail, dictionary data that is used to extract conversion candidates at the time of character conversion, and the like are stored.

  The communication unit 26 establishes a radio signal line by a CDMA system or the like with a base station via a channel assigned by the base station, and performs telephone communication and information communication with the base station.

  The operation unit 28 includes, for example, an operation key 3 to which various functions such as a power key, a call key, a numeric key, a character key, a direction key, a determination key, and a call key are assigned, and a direction and determination key 4. When these keys are input by a user operation, a signal corresponding to the operation content is generated. The generated signal is input to the input data acquisition unit 29 as a user instruction.

  The input data acquisition unit 29 generates a control signal based on the signal generated from the operation unit 28 and the input setting, and inputs the generated control signal to the main control unit 22. For example, in the case of character input, one character is extracted from characters assigned to each key based on the number of times each key of the operation key 3 is operated, and is output to the main control unit 22 as character information. In the present embodiment, the operation keys 3 are composed of 15 keys, of which 10 keys are assigned such that 1 to 9 and 0 are input in the mode for inputting numbers. Yes. Furthermore, keys assigned with numbers 1 to 9 are assigned so that characters in lines are entered from line to line in the character input mode. It is assigned to input "Wa", "O", and "N". In addition, the key to which each line is assigned is also assigned the roar of that line and the above-mentioned numbers. The characters assigned to these keys have a predetermined arrangement order. Specifically, the “1 a” key to which “A” and “1” are assigned is “A”, “I”, “U”, “E”, “O”, “A”, “I”, “ Arrangement order of “ぅ”, “e”, “ぉ”, “1” is set. The order of arrangement is toggled. That is, the characters assigned to the keys are set so as to circulate, and “1” is followed by “a”, and then the arrangement order is repeated.

  Further, the input data acquisition unit 29 detects pressing of the operation key, and determines a character to be displayed (selected) among characters in the arrangement order based on the number of pressings. When the same operation key 3 is pressed continuously, that is, when the same operation key 3 as that immediately before (exactly one key among the operation keys 3) is pressed, the input data acquisition unit 29 A character (input candidate character) to be displayed in the arrangement order is selected based on the number of times of pressing. Further, the input data acquisition unit 29 operates when a different operation key 3 is pressed, that is, an operation key 3 different from the operation key 3 pressed immediately before (precisely, one key among the operation keys 3). When is pressed, the first character in the arrangement order of the pressed operation keys 3 is displayed.

  The audio processing unit 30 executes processing of an audio signal input to the microphone 5 and an audio signal output from the receiver 6.

  The display unit 32 includes a display panel (such as the main display 2M described above) configured by a liquid crystal display (LCD, Liquid Crystal Display), an organic EL (Organic Electro-Luminescence) panel, and the like. A video corresponding to the video data supplied via the unit 33 and an image corresponding to the image data are displayed on the display panel.

  Next, the operation of the portable electronic device 1, the operation input to the operation unit 28, and the processing in the main control unit 22 will be described. Here, FIG. 4 is a flowchart showing an example of the processing operation of the portable electronic device, and FIG. 5 is an explanatory diagram for explaining the operation of the portable electronic device. Note that the flowchart shown in FIG. 4 is a flowchart showing an example of processing for creating and sending an electronic mail. 6 to 8 are explanatory diagrams for explaining the operation of the mobile electronic device. Specifically, FIG. 6 is a diagram showing a display example in the case where conversion is performed by inputting “Chouki” as a character string, and FIG. 7 is entered as “Do not flick” as a character string. It is a figure which shows an example of a display example at the time of selecting KY word conversion menu after converting. FIG. 8 is a diagram showing an example of a display example when the KY word conversion menu is selected after “I ’m sorry, I ca n’t read super air” as a character string.

  First, when the main control unit 22 of the portable electronic device 1 detects the activation operation in step S12, that is, when the activation instruction for the character input function is detected, the character input screen is activated in step S14. Specifically, the main control unit 22 activates the character input screen when detecting an instruction to activate the mail application program or an instruction to activate text input by an operation by the operator. Further, the main control unit 22 reads software data for performing character conversion from the storage unit 24 and activates the software.

  Next, after starting the character input screen in step S14, the main control unit 22 detects a key press operation in step S16, that is, the input data acquisition unit 29 indicates that a character input operation has been performed by the operator. If detected, character display processing is performed as step S18. That is, the main control unit 22 detects an operator's character input operation in step S16 and step S18, and a character or a character string (hereinafter referred to as “character string”) based on the input operation is displayed on the display unit 32. Display. Note that the character string displayed in step S18 is a character string before conversion, and the character string input by the operator is displayed as it is.

  After performing the character display process in step S18, the main control unit 22 performs a dictionary reading process as step S20. Specifically, the main control unit 22 reads dictionary data stored in the storage unit 24 in order to create conversion candidates for converting a character string into kanji or the like. The main control unit 22 may read all the data of the dictionary data from the storage unit 24, but the data to be read in accordance with the character string that has been input and is not fixed (targeted for processing) in step S16. You may narrow down.

  After performing the dictionary data reading process in step S20, the main control unit 22 performs character string word division processing in step S22. That is, in order to create a conversion candidate, a character string to be converted is divided into words. Here, the method for dividing the character string into words is not particularly limited. For example, the character string can be divided by extracting words in the character string while comparing the character string with words in the dictionary data. Alternatively, the character string may be divided at different character positions and divided into a plurality of different patterns.

  After dividing the character string to be converted into words in step S22, the main control unit 22 creates a KY word conversion candidate in step S24. Here, the KY word is a kind of initial abbreviation that is obtained by converting the initial letters of each word constituting a character string into Roman letters and connecting only the leading alphabets. As shown in FIG. 5, the input kana of a word corresponds to the alphabet. Specifically, "A" corresponds to "A", "I" corresponds to "I", and "ka" "ki" "ku" "ke" "ko" , “K” corresponds. In addition, lowercase letters of the alphabet correspond to each roar. Specifically, “a” corresponds to “a”, “i” corresponds to “i”, and “y” corresponds to “y”. The main control unit 22 generates a KY word by converting the first letter of each divided word into Roman letters and connecting the first alphabet of each word. Further, when the character string is divided into a plurality of patterns of words, the main control unit 22 converts each pattern into a KY word.

  After creating the KY word conversion candidate in step S24, the main control unit 22 performs conversion candidate character display processing in step S26. That is, a character string that is a conversion candidate is displayed on the display unit 32. Specifically, a conversion candidate created based on the KY word conversion candidate created in step S24 and the word and dictionary data divided in step S22 (for example, a character string obtained by converting at least part of the character into kanji or converted into katakana). Displayed on the display unit 32. The number of conversion candidates to be displayed is not particularly limited and may be an arbitrary number. Further, the conversion candidates to be displayed may be changed by scroll operation by the operator.

  After displaying the conversion candidate character on the display unit 32 in step S26, the main control unit 22 determines whether a selection operation has been input in step S28. That is, it is determined whether an operation for selecting one of a plurality of conversion candidates is input by the operator. The operation for selecting a conversion candidate is exemplified by an operation for changing the selected conversion candidate in response to an input such as a cross key.

  If it is determined in step S28 that no selection operation has been input (No), the main control unit 22 detects whether a phrase change process has been input in step S29. Here, the phrase change process is a process of changing the position where the conversion candidate character string is divided into words, and an instruction to change the phrase position is input by the operator operating the cross key or the like. When the main control unit 22 detects the phrase change process in step S29 (Yes), the main control unit 22 proceeds to step S20. If the main control unit 22 determines Yes in step S29 and then proceeds to step S22, the main control unit 22 divides the character string to be converted into words based on the phrase input in step S29.

  When the phrase change process is not detected in step S29 (No), the main control unit 22 proceeds to step S16. That is, the main control unit 22 determines that the input of the character string to be converted is not finished when there is no input of the conversion candidate selection operation and there is no phrase change processing, and the operator inputs the character Detect operations. Thereafter, the process from step S18 to step S28 is performed on the character string including the newly added character as a conversion target.

  For example, as shown in FIG. 6, when the character string “Cho” is input by operating the operation key 3, the main control unit 22 selects “super”, “long”, “book”, “ “Butterfly”, “Cho” and “Chow” are created as conversion candidates and displayed on the display unit 32, and “C” and “CU” are created as KY word conversion candidates and displayed on the display unit 32. Here, the KY word conversion candidate “C” is created by making “Cho” as one word, and the KY word conversion candidate “CU” is created by dividing “Cho” and “U” into words respectively. Yes.

  After that, if the character input is continued without inputting the confirmation process and “kuuki” is inputted, the character string becomes “chouuki”. When the character string is “Choukuuki”, “Super Air”, “Long Text”, “Choukiuki”, “Chouukuuki” are created based on the dictionary data and displayed as conversion candidates, “CK”, “CUU” is created as a KY word conversion candidate and displayed on the display unit 32. At this time, the KY word conversion candidate “CK” is created by dividing “cho” and “kuuki” into words, and the KY word conversion candidate “CUU” is “cho” and “ku”. Created by dividing "Uki" into words.

  Next, if it is determined in step S28 that a selection candidate has been input (Yes), the main control unit 22 determines whether a KY word has been selected as a conversion candidate in step S30. That is, it is determined whether the KY word conversion candidate created in step S24 is selected from the conversion candidates. If it is determined in step S30 that the KY word has been selected (Yes), the main control unit 22 performs dot display processing on the divided word as step S32. Specifically, a dot is displayed above the character that is determined as the initial character in the selected KY word conversion candidate, that is, the first character of the segmented word, which is the basis of the alphabet display. The dot display position is not particularly limited as long as the first character of the word can be recognized.

  Specifically, as illustrated in FIG. 6, when a character string to be converted is selected from conversion candidates for the character string “Choukuuki”, when a KY word conversion candidate “CK” is selected as a selection candidate, A dot is displayed at the top of “Chi”, which is an initial of “Cho”, and “KU”, which is an initial of “Kuuki”. In addition, when the KY word conversion candidate “CUU” is selected as a selection candidate, “Chi” that is the initial of “Cho”, “Uku” that is the initial of “U”, and “Uki” are the initials of “Uki”. A dot appears at the top of "U".

  If the main control unit 22 determines in step S30 that the KY word is not selected as a conversion candidate (No), or if dot display processing is performed on the divided word in step S32, the word confirmation operation is performed in step S34. Determine the input. Examples of the operation to be confirmed include an operation of pressing the enter key and an operation of inputting the next character. If the main control unit 22 determines in step S34 that no word determination operation has been input (No), the main control unit 22 proceeds to step S28 and repeats the above operation.

  If the main control unit 22 determines in step S34 that the word confirmation operation has been input (Yes), the main control unit 22 determines the character string to be converted based on the selected character string, and further, in step S36, character input is performed. Is determined to be continued. Here, when the character key is pressed and the input operation of the next character is detected, the main control unit 22 determines that the character input is continued. If it is determined in step S36 that character input is continued (Yes), the main control unit 22 proceeds to step S16 and repeats the above operation. If it is determined in step S36 that character input is not continued (No), the main control unit 22 detects whether the menu key is pressed in step S38. Here, the menu key is one of the operation key 3 and the direction / decision key 4, and is a key for outputting an instruction to display a menu screen when pressed. If the main control unit 22 does not detect pressing of the menu key in step S38 (No), the main control unit 22 proceeds to step S54.

  When the main control unit 22 detects that the menu key is pressed in step S38 (Yes), the main control unit 22 updates the display of the display unit 32 as step S40. Specifically, a menu screen is displayed. Next, when the main control unit 22 detects that the KY word conversion candidate menu has been selected as step S42, the main control unit 22 proceeds to step S44. Here, the KY word conversion candidate menu is a function that can be selected on the menu screen, and is a function that converts a character string that has undergone conversion confirmation processing into a KY word. The character string may be selected by the user, or may be automatically extracted by the main control unit 22 according to the state at the time of menu selection. In this control example, the menu is displayed on the screen and then the KY word conversion candidate menu is selected. However, a plurality of functions are displayed on the menu screen displayed in step S40, and the KY word conversion candidate menu is displayed. Various functions other than those may be executed.

  Moreover, the main control part 22 performs the word division | segmentation process of a character string as step S44. The main control unit 22 divides the character string into words based on the conversion determined in step S34. Next, after dividing the character string into words in step S44, the main control unit 22 creates KY word conversion candidates in step S46. At this time, the initials of each word may be determined based on the kana input before conversion or may be determined based on the reading input in the dictionary data. In addition, it is preferable that the operator can select. After creating the KY word conversion candidate in step S46, the main control unit 22 performs conversion candidate character display processing in step S48. That is, the KY word conversion candidate created in step S46 is displayed on the display unit 32.

  After displaying the conversion candidate on the display unit 32 in step S48, the main control unit 22 performs underline display processing of the divided word as step S50. That is, an underline is displayed on the word to be converted. At this time, the underline is displayed corresponding to the divided word. That is, a separate underline is displayed for each word.

  Specifically, first, as shown in FIG. 7, when the main control unit 22 is input as a character string “cannot be read”, “super air readable”, “long phrase” “Cannot read right” and “Cannot read” are created as conversion candidates and displayed on the display unit 32, and “CKY” and “CUY” are created as KY word conversion candidates and displayed on the display unit 32. At this time, the KY word conversion candidate “CKY” is created by dividing “Cho”, “Kuuki”, and “Yomei” into words, and the KY word conversion candidate “CUY” ”,“ Uki ”, and“ I can't read ”are divided into words.

  Next, “cannot read the super air” is selected and confirmed as the conversion candidate character, and “cannot read the super air” is displayed on the display unit 32. The above process is an example when the word is confirmed in step S34. Thereafter, when the menu key is pressed, the KY word conversion candidate menu is displayed, and when the KY word conversion candidate menu is selected, “CKY” is displayed as the conversion candidate. At this time, “super”, “air”, and “unreadable” are underlined according to the division of words.

  After underlining the word divided in step S50, the main control unit 22 determines whether there is a definite input (an input for determinating the process) as step S52. That is, it is determined whether an instruction to confirm with the KY word created in step S46 or the character before conversion is input. If it is determined in step S52 that there is no process confirmation input (No), the main control unit 22 detects whether a phrase change process is input in step S53. When the main control unit 22 detects the phrase change process in step S53 (Yes), the main control unit 22 proceeds to step S44. If the main control unit 22 determines Yes in step S53 and then proceeds to step S44, the main control unit 22 divides the character string to be converted into words based on the phrase input in step S53. .

  Specifically, as shown in FIG. 7, based on the changed phrase, “Neighboring” is segmented into words, and “unusually floating” is created and displayed as a conversion candidate. Further, a KY word conversion candidate “CUUMN” is created and displayed in accordance with the word. The KY word conversion candidate “CUUMN” is created by dividing “Floating Ukiyo-no” into five words “Author”, “Floating”, “Ukiyo”, “Eye”, and “None”. The five words are displayed with separate underlines.

  As another example, after being input by an operator and performing character input and conversion, as shown in FIG. 8, “I ’m sorry, I ca n’t read super air” is created as a character string. When it is detected that the menu is selected in step S38 to step S42 and “KY word conversion candidate” is selected, a screen for selecting the start point of the portion to be converted to KY word is displayed. After the screen is displayed, when the operator inputs the direction and the operation of the determination key 4, the cursor of the display unit is moved in accordance with the input, and the start point is determined based on the determination of the operator.

  Next, when the start point is determined, a screen for selecting the end point of the portion to be converted to the KY word is displayed. After the screen is displayed, when the operator inputs an operation of the direction and the determination key 4, the cursor of the display unit is moved according to the input, and the end point is determined based on the determination of the operator. When the start point and the end point are determined, the character string to be converted is divided into words to create a KY word. In this embodiment, “Unable to read super air” is selected as the character string, so “CKY” and “CUUMN” are created as KY words.

  After that, when a process for selecting and confirming “CKY” is input, “Unable to read super air” is converted to “CKY”, “Sorry, I am from CKY”, and the KY word conversion is completed. As described above, the start point and the end point of the character string to be converted into the KY word may be determined based on the operation of the operator.

  If the phrase change process is not detected in step S53 (No), the main control unit 22 proceeds to step S16 and repeats the above-described process.

  Next, when the main control unit 22 determines that there is a confirmed input in step S52 (Yes) or determines in step S38 that the menu key is not pressed (No), in step S54, the main control unit 22 adds the confirmed character string data. The included KY word and the corresponding character are linked and stored. That is, the KY word is stored in association with the character that has been converted.

  In step S56, the main control unit 22 determines whether an input completion instruction, that is, a sentence creation end instruction has been input. If it is determined in step S56 that there is no input completion instruction (No), the main control unit 22 proceeds to step S16, and continues character input and sentence creation. Further, when determining that there is an input completion instruction (Yes) in Step S56, the main control unit 22 determines whether or not to perform a mail transmission process in Step S58. Here, whether or not to perform the mail transmission process is determined based on whether or not a transmission instruction by the operator is input. When it is detected that the transmission instruction is input, the mail transmission process is performed. Is determined.

  If it is determined in step S58 that transmission processing is to be performed (Yes), the main control unit 22 performs mail transmission processing in step S60, transmits the created sentence, and ends the processing. The mail transmission processing is performed by the main control unit 22 using mail software and performing data communication processing with other terminals and base stations via the communication unit 26. If the main control unit 22 determines in step S58 that the mail transmission process is not performed (No), the main control unit 22 ends the process. If mail transmission is not performed, the created text data may be stored in the storage unit 24.

  In this way, the character string to be converted is divided into words, and each word is converted to the first alphabet when the word or the first character of the word is converted to Roman characters, thereby converting the character string into a KY word. be able to. As a result, even if the KY word is not stored in the dictionary, it can be converted into the KY word, so that the operator does not need to input the alphabet to create the KY word and inputs the kana. You can also create KY words. As a result, it is possible to perform conversion desired by the operator, and operability can be improved. In addition, since it is possible to convert to the latest and various KY words without using the dictionary function, the trouble of updating the creator of the dictionary data can be omitted, and the used KY words can be changed. There is no need to always research. As a result, the burden on the administrator can be reduced.

  In addition, as in the present embodiment, KY words can be used more effectively by making lowercase letters correspond to stuttering. For example, in recent years, there is a case where a stuttering is used for a character of a line in a text such as an email. In such a case, it can be recognized that a stuttering is used for a character string. For example, “Happy New Year” is changed to “Akake New Year” and this character string is changed to “ao”. As a result, it is possible to recognize that the roaring sound is used in the original character string, such as “Akemashite and praise”.

  In this embodiment, the words are directly used as KY words to connect the sentences. However, when the last word of the KY word is a part of speech other than a noun, for example, a verb, an adverb, an adjective, It is preferable to supplement the auxiliary verb. For example, to convert “I ca n’t read the super air” to “CKY” in “I ’m sorry, I ca n’t read it”, I ’ll add “D” between “CKY” and “Karasa” I ’m sorry, I ’m CKY. In this way, it is preferable to make the sentence when converted to the KY word more natural and easy to read by supplementing the particle or auxiliary verb.

  Next, with reference to FIGS. 9 and 10, a case where a KY word converted sentence is displayed will be described. Here, FIG. 9 is a flowchart showing the processing operation of the portable electronic device, and FIG. 10 is an explanatory diagram for explaining the operation of the portable electronic device. First, an example of display processing for displaying a character string converted into a KY word will be described with reference to FIG. First, when the main control unit 22 of the mobile electronic device 1 detects that a mail reception notification is sent from a base station or the like, a mail reception process is performed as step S70. After performing the mail reception process in step S70, the main control unit 22 determines whether there is KY word conversion data in the mail data received in step S72. That is, it is determined whether there is linked data created in step S54 described above in addition to mail text data. If the main control unit 22 determines that there is KY word conversion data (Yes) in step S72, the KY word conversion data, that is, the association data sent in association with the KY word is stored in the buffer in step S74. It progresses to back step S76. Here, the buffer may use the processing area of the main control unit 22 or the storage area of the storage unit 24. If the main control unit 22 determines that there is no KY word conversion data (No) in step S72, the main control unit 22 proceeds to step S76 as it is.

  Next, in step S76, the main control unit 22 stores the received mail data, that is, text data, in a buffer. If an image or the like is attached to the mail, those data are also stored in the buffer.

  After storing the mail data in the buffer in step S76, the main control unit 22 detects the received mail display operation in step S78, and performs a mail list display process in step S80. That is, after storing the mail in the buffer, the main control unit 22 is in a standby state until the received mail display operation is detected. Also, other mail may be received in this standby state.

  After displaying the mail list in step S80, the main control unit 22 performs selected mail preview processing in step S82. Specifically, a part of the contents of the mail temporarily selected by the cursor or the like in the mail list and the title can be displayed. The operator selects the mail to be displayed with reference to the contents displayed in the preview from the mail list. When the operator selects mail, the main control unit 22 detects the operator's selection operation as step S84.

  When detecting the operator's selection operation in step S84, the main control unit 22 determines whether there is KY word conversion data in the selected mail (selected mail) in step S86. If the main control unit 22 determines in step S86 that there is no KY word conversion data (No) in the selected mail, it calls a mail display layout in step S88. The mail display layout is a frame for displaying mail without KY word conversion data. The layout data is stored in the storage unit 24. When the main control unit 22 calls the mail display layout, the main control unit 22 proceeds to step S94.

  If it is determined in step S86 that the selected mail has KY word conversion data (Yes), the main control section 22 calls (reads out) a mail display layout with a KY word display area in step S90. The mail display layout with a KY word display area is a frame for displaying mail with KY word conversion data. In addition to an area for displaying normal text, data associated with a KY word is displayed. There is an area to let you. The layout data in step S90 is also stored in the storage unit 24. After calling the mail display layout with the KY word display area in step S90, the main control unit 22 performs KY word conversion data list display processing in the KY word display area in step S92. Specifically, as necessary, the data associated with the KY word is processed in the received data so that the data associated with the KY word can be displayed in the KY word display area.

  After completing the process of step S88 or step S92, the main control unit 22 performs mail display processing in the mail display area as step S94. That is, the data is processed so that the text data of the selected mail is displayed in the mail display area. Thereby, the data of the selected mail is displayed on the display unit.

  Next, the main control part 22 determines whether selection operation is detected as step S96. Specifically, it is detected whether an operation selected by the operator is input. For example, it is determined whether or not a selection operation for switching the display area from the mail display area to the KY word display area and vice versa is input. If it is determined in step S96 that the selection operation has been detected (Yes), the main control unit 22 updates the display of the selection area in step S98. For example, the size of the area displayed on the display unit 32 is switched, the front-rear relationship between the areas is switched, or the display in the area is switched. In addition, what is necessary is just to update the display update method with various patterns by an operator's operation and setting.

  When it is determined in step S96 that the selection operation has not been detected (No), or when the process of step S98 is completed, the main control unit 22 detects whether a scroll operation is input as step S100. In the present embodiment, the scroll operation is an operation in which the up and down keys of the direction key of the direction and determination key 4 are pressed. When the main control unit 22 detects a scroll operation in step S100 (Yes), the main control unit 22 performs scroll display processing of the selected area as step S102. Specifically, the scroll amount is detected according to the time and number of times the operator presses the up / down key, and the display area is moved based on the scroll amount.

  If it is determined in step S100 that the scroll operation is not detected (No), or if the process of step S102 is completed, the main control unit 22 determines whether there is an end instruction as step S104. That is, it is determined whether an instruction to end the mail display process is input. If it is determined in step S104 that there is no end instruction (No), the main control unit 22 proceeds to step S96, repeats the above operation, and if it is determined in step S104 that there is an end instruction (Yes), ends the process.

  Next, a specific example will be described with reference to FIG. As shown in FIG. 10, “I can't read it” is converted to “I can't read super air”, and then an email converted to “CKY” by the KY word conversion function is sent. When the recipient who received this mail displays the mail, information indicating that “CKY” is an abbreviation of “cannot read the super air” in the KY word display area as shown in the lower right diagram of FIG. Is described. On the other hand, when CKY is input as an alphabet, CKY is simply displayed as shown in the lower left diagram of FIG.

  As described above, the KY word conversion function stores the KY word and the character string to be converted in correspondence with each other, and displays it, thereby sending an email to an operator who cannot understand the meaning of the KY word. Even in this case, the meaning of the sentence can be understood. Thereby, even when the KY word is used, it is possible to prevent the meaning from being misunderstood, and an operator who does not know the KY word can learn the KY word.

  In this embodiment, the association data is displayed in another area. However, the present invention is not limited to this, and the KY word and the character string before conversion are associated with the end of the sentence data. You may make it display. Thereby, even when transmitting to a terminal that does not support the KY word conversion function, it is possible to understand the correspondence between the KY word and the original character string (word).

  Here, in the above-described embodiment, a character string of kana-character mixed kanji characters is converted into KY words, but the present invention is not limited to this. The present invention can be used in various cases where a character string is divided into words and shortened to an acronym acronym. In the case of English sentences, each English word is concatenated with only the first alphabet to create an acronym acronym. You may make it do. In addition, acronyms can be created in various languages, not limited to English.

As described above, the character input device, the character display system, and the character conversion method according to the present invention are used in an apparatus and a method for converting an input character string into another character string and / or displaying the converted character. Especially useful.
