Description

  The present invention relates to a technique for inputting characters, and more particularly to a technique for improving operability when inputting Roman characters.

  In recent years, various electronic devices such as mobile phones and audio devices have been equipped with character input devices for inputting characters. For example, in the case of a mobile phone, the name of the other party and the e-mail address are input. For example, in an audio apparatus, a music title and an artist name can be registered in association with audio data.

As a character input device, one in which an alphabet can be input by rotating one rotary operator is known (see, for example, Patent Document 1 and Patent Document 2). In this type of character input device, when an alphabet is input by rotating a rotary operator, the alphabet is sorted in descending order from A to Z or in ascending order from Z to A according to the direction of rotation during the rotating operation. By changing the alphabet, one alphabet is displayed on the display panel, and when the alphabet to be input is displayed, pressing the confirmation button or the like allows the one alphabet to be entered.
Japanese Patent Laid-Open No. 4-245837 JP-A-5-3506

However, when inputting Japanese kana (kana) in Roman characters using the above character input device, the rotary operator is rotated until the desired alphabet is displayed in descending order from A or in ascending order from Z. There is a problem that it takes time to operate until the target alphabet is displayed.
Such a problem is not limited to the rotary operation element, but of course also applies to a push operation type operation element such as a cursor key for sequentially selecting alphabets by an increment operation or a decrement operation.

  The present invention has been made in view of the above-described circumstances, and improves a Roman character input operation, thereby shortening an input time, a Roman character input method, a Roman character input method, a Roman character input program, and an electronic apparatus. The purpose is to provide.

And displaying on the display unit one character each time the child is operated.

The present invention, in the above invention, if the consonant alphabets representing the Kana consonant is inputted, the consonant alphabets contracted sound only when there is a possibility to configure the voiced or Nejihan dullness Kana screws, Kana vowel The alphabet “Y”, the alphabet “H”, and the input consonant alphabet are displayed on the display unit one by one each time the operator is operated , following the vowel alphabet to be expressed. .

Further, in the present invention, when the vowel alphabet representing the kana vowel is selected and confirmed , or when the first alphabet is selected and confirmed , the vowel alphabet and the consonant alphabet, or the alphabet “ Characters “A” to “Z” are displayed on the display unit one character each time the operation element is operated .
Note that an electronic apparatus including the Roman character input device according to any one of the above inventions also corresponds to the present invention.

In order to achieve the above object, the present invention includes a storage unit for storing the "Z" alphabet "A" operator alphabetic character from the alphabet, which is stored in the storage unit is operated Each time a character is selected and displayed on the display unit, and when the selection / confirmation operation of the alphabet displayed on the display unit is performed, the one-letter alphabet displayed on the display unit is input. In the Romaji input method for inputting Romaji, when a consonant alphabet representing a Kana consonant is input , the alphabet “A” to “Z” stored in the storage unit is selected in order. The vowel alphabets “A”, “I”, “U”, “E”, and “O”, which represent vowels, are set, and the operator is followed by the consonant alphabet. And displaying on the display unit one character each time it is created.

In order to achieve the above object, the present invention includes a storage unit for storing the "Z" alphabet "A" operator alphabetic character from the alphabet, which is stored in the storage unit is operated Each time a character is selected and displayed on the display unit, and when the selection / confirmation operation of the alphabet displayed on the display unit is performed, the one-letter alphabet displayed on the display unit is input. , Romaji input device configured to be able to input Romaji, when a consonant alphabet representing a Kana consonant is input, the alphabet is sequentially selected from alphabets “A” to “Z” stored in the storage unit Are “A”, “I”, “U”, “E”, and “O”, which are vowel alphabets representing kana vowels. Providing Romaji program for causing to function as means for displaying on the display unit one character each time the child is operated.

  According to the present invention, when a consonant alphabet representing a kana consonant is input, the alphabet to be selected according to the operation of the operator is only the alphabet that constitutes one kana together with the consonant alphabet. The number of operations of the operation element until the alphabet is displayed can be reduced, the operability of the Romaji input characters can be improved, and the input time required for Romaji input can be shortened.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view showing an external configuration of a Roman character input device according to the present embodiment, and FIG. 2 is a block diagram showing a functional configuration of the Roman character input device. As shown in FIG. 1, the Roman character input device 1 is provided with a rotary operator 3 and a display panel 4 on the front surface of the device body 2. The rotary operation element 3 includes a rotary switch and a center push switch disposed at the center thereof, and can be rotated left and right and pressed. The display panel 4 displays input characters when inputting Roman characters.

  The functional configuration of the romaji input device 1 will be described. As shown in FIG. 2, the romaji input device 1 is an operation for detecting the rotation operation 3 and the display panel 4, and the rotation operation and the pressing operation on the rotation operation device 3. Control for executing various controls such as displaying the alphabet on the display panel 4 based on the detection unit 5, the storage unit 6 for storing various data such as alphabet data and programs, and the operation detected by the operation detection unit 5. Part 7.

  The operation of the Roman input character will be described. When the rotary operation element 3 is rotated, the rotation direction and the rotation operation amount of the rotation operation are detected by the operation detection unit 5 and output to the control unit 7 as rotation operation information. . When the rotation operation information is input, the control unit 7 selects one alphabet for each predetermined rotation amount and displays it on the display panel 4 (FIG. 3A). At this time, if the rotation operation is a right rotation operation, the control unit 7 changes the alphabet of one character displayed on the display panel 4 in descending order of A to Z directions (FIG. 3B). On the contrary, when the rotation operation is a left rotation operation, the alphabet is changed in ascending order from Z to A.

  When the rotary operation element 3 is pressed, the pressing operation is input to the control unit 7 via the operation detection unit 5, and the control unit 7 determines the currently displayed alphabet as an input character. In this way, the alphabet is input character by character, and various Roman character strings such as names and music titles are input as shown in FIG. Completion of the Roman character input is notified by depressing the rotary operator 3 following the depressing operation of the rotary operator 3 for determining the input character. It is stored in the storage unit 6.

  Romaji input will be described with reference to an example of Romaji notation based on the Hebon (standard) formula. As shown in FIG. 4, kana is represented by a combination of vowels and consonants. ”,“ U ”,“ E ”, and“ O ”correspond to the vowel alphabet, and the letters“ K ”,“ S ”,“ T ”,“ C ”,“ N ”,“ H ”,“ F ”, “M”, “Y”, “R”, “W”, “G”, “Z”, “D”, “B”, “P”, and “J” correspond to consonant alphabets.

  Furthermore, among these consonant alphabets, “K”, “S”, “C”, “N”, “H”, “M”, “R”, “G”, “B” and “P” are: When the alphabet “Y” or “H” is inserted between the consonant alphabet and the vowel alphabet, the roaring sound, the hazy sound, and the hazy hazy sound are written. In the present embodiment, the clear sound “tsu” is expressed as “TSU” in the Hebon type, but in the present embodiment, it is expressed as “TU”, and the sound repellent “n” is indicated by the alphabet “N”. Although expressed by one character, in the present embodiment, the alphabet “N” is expressed by “NN” which is overlapped twice.

  As described above, in the Roman alphabet, after the consonant alphabet is input, either the vowel alphabet or “Y” or “H” (in addition to “N” in the alphabet “N”) is input. Therefore, no other alphabet is entered. Therefore, in the present embodiment, when the input alphabet is a consonant alphabet, the alphabet displayed in accordance with the rotation operation of the rotary operator 3 is not “A” to “Z” but one character together with the consonant alphabet. By limiting to only the alphabet constituting the minute kana, that is, only the vowel alphabet and “Y”, “H”, the target alphabet can be easily selected. Hereinafter, the operation of the control unit 7 when inputting Roman characters will be described in detail with reference to FIG.

FIG. 5 is a flowchart of a Roman character input control process performed when inputting Roman characters.
As shown in this figure, the control unit 7 sequentially displays alphabets “A” to “Z” in accordance with the rotation operation of the rotary operation element 3 in order to accept the input of the first character (step Sa1). Then, it is determined whether or not the input alphabet that has been finalized by the pressing operation of the rotary operator 3 is the vowel alphabet (step Sa2). If the input alphabet is a vowel alphabet (step Sa2: YES), it means that the input of one character has been completed, and it is specified whether the next input alphabet is a vowel alphabet or a consonant alphabet Not. Therefore, in this case, the control unit 7 determines whether or not the Roman character input has been completed by determining whether or not the rotary operation element 3 has been pressed (step Sa3), and when the Roman character input has not been completed. (Step Sa3: NO), the processing procedure is returned to step Sa1 to continue the input of the next character, and when the Roman character input is completed (step Sa3: YES), the processing is ended.

On the other hand, if the input alphabet is not a vowel alphabet as a result of the determination in step Sa2 (step Sa2: NO), it is estimated that the input alphabet is a consonant alphabet. As described above, when a consonant alphabet is input, if the input purpose is a stuttering sound, a suspended sound, or a suspended halftone sound, the consonant alphabet is input with “Y” or “H” instead of the vowel alphabet. Can be done. Therefore, when the input alphabet is a consonant alphabet that can be a stuttering sound, a cloudy sound, or a hazy semitone (step Sa4: YES), the control unit 7 executes a roaring / turbidity sound / hungry halftone process described later (step). Sa5). On the other hand, when the input alphabet is not a consonant alphabet that can be a noise, a cloudy sound, or a cloudy halftone (step Sa4: NO), the control unit 7 performs “A” to “Z” during the rotation operation of the rotary operator 3. Instead of sequentially displaying all the alphabets up to “”, only the vowel alphabets are displayed and input (step Sa6).
In this embodiment, consonant alphabets that can be a stuttering sound, a suspended sound, or a hazy semi-turbid sound are “K”, “S”, “C”, “N”, “H”, “M”, “R”, “ G ”,“ B ”and“ P ”.

FIG. 6 is a flowchart of the processing of the stuttering / turbidity / darkness / semi-turbidity processing.
As shown in FIG. 4, in the Hebon type, the alphabet “H” is input when a stuttering is input only when “C” and “S” are input as consonant alphabets. Therefore, as shown in FIG. 6, the control unit 7 first determines whether or not the input alphabet is “C” or “S” in the stuttering / suspension / semi-speech processing (step Sb1). , “C” or “S” (step Sb1: YES), the alphabet to be displayed at the time of the rotation operation of the rotary operator 3 is set to only the vowel alphabet and “H”, and the next alphabet is input (step Sb2). . Then, the control unit 7 determines whether or not the input alphabet is “H” (step Sb3). If it is “H” (step Sb3: YES), the alphabet to be input next is determined. Is always a vowel alphabet, so that only the vowel alphabet is displayed and input when the rotary operator 3 is rotated (step Sb4). If a vowel alphabet is input in step Sb2 (step Sb3: NO), the control unit 7 indicates that the input of one character has been completed. Exit.

  Next, if the input alphabet is not “C” or “S” as a result of the determination in step Sb1 (step Sb1: NO), the sound repellent “n” may be input. Is determined to be “N” (step Sb5). When the input alphabet is “N” (step Sb5: YES), not only the sound repellent “n” but also the clear sound (“na”, “ni”, “nu”, “ne”, “no”) and A roaring sound (“Nya”, “Nyu”, “Nyo”) may be input. Therefore, in this case, the control unit 7 displays and inputs only the vowel alphabet, “Y” and “N” when the rotary operator 3 is rotated (step Sb6). As a result, the input alphabet is input. It is determined whether or not it is “Y” (step Sb7). If it is “Y” (step Sb7: YES), the next input alphabet is always a vowel alphabet. During the rotation operation, only the vowel alphabet is displayed and input (step Sb8). On the other hand, when a vowel alphabet or “N” is input in step Sb6 (step Sb7: NO), the control unit 7 indicates that the input of one character has been completed.拗 End the half-sound processing.

  If the input alphabet is not “N” as a result of the determination in step Sb5 (step Sb5: NO), the alphabet “Y” may be input in addition to the clear sound, and a roaring sound or a hazy sound may be input. Therefore, the control unit 7 displays and inputs only the vowel alphabet and “Y” when the rotary operator 3 is rotated (step Sb9). As a result, whether or not the input alphabet is “Y”. (Step Sb10), and if it is “Y” (step Sb10: YES), since the next input alphabet is always a vowel alphabet, only the vowel alphabet is used when the rotary operator 3 is rotated. Display and input (step Sb11). On the other hand, when the vowel alphabet is input at the input of step Sb9 (step Sb10: NO), the control unit 7 indicates that the input of one character has been completed. The muddy sound processing ends.

  As described above, according to the present embodiment, when a consonant alphabet representing a kana consonant is input, an alphabet to be selected according to the operation of the rotary operator 3 is configured with a kana for one character together with the consonant alphabet. Since only the alphabet is used, the number of operations of the operator until the target alphabet is displayed can be reduced, the operability of the Roman input characters can be improved, and the input time required for inputting the Roman characters can be shortened.

In the present embodiment, when inputting the first one alphabet of the kana for one character, the alphabets “A” to “Z” are selected in order (step Sa1 in FIG. 5). Only the vowel alphabets and consonant alphabets used for Roman character input may be selected and displayed in order.
Further, in this embodiment, in order to make it possible to input the prompt sound “tsu”, when a consonant alphabet is input, the vowel alphabet, the alphabet “S” is used as an alphabet that constitutes a kana for one character together with the consonant alphabet. Of course, in addition to “Y”, the consonant alphabet may be added.

Further, in the present embodiment, when inputting the first one alphabet of kana for one character, for example, “@”, “′”, “,”, “.”, “-”, Space characters, numbers It is also possible to select and display various characters and symbols that can be used for e-mail addresses such as “0” to “9”, music titles, names, and punctuation marks.
Moreover, in this embodiment, the Roman character input rule is not limited to the Hebon type, and may be a Japanese type or a command type.
Further, in this embodiment, a switching operation element for switching between Roman input and alphabet input is newly provided, and when alphabet input is designated by the switching operation element, according to the rotation operation of the rotation operation. The alphabets “A” to “Z” may always be selected and displayed in order. As a result, it is possible to input characters other than Roman characters.
Further, in the present embodiment, the rotary operation element 3 is illustrated as an example of the operation element. However, the present invention is not limited to this. For example, a cursor key capable of incrementing and decrementing is provided, and the cursor key is incremented or decremented. Alternatively, the alphabet may be selected and displayed in order.

Next, as an application example of the present invention, a case will be described in which the Roman character input device according to the present invention is incorporated in a hands-free call device mounted on a vehicle.
