Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable telephone, and more particularly to a technique for inputting characters.

[0002]

2. Description of the Related Art In recent years, portable telephones have been provided with many useful functions in addition to the basic call function.
The character input function is one of them. This character input function,
This function is for inputting Hiragana, Kanji, Katakana, English characters, etc. when creating an e-mail text.

When a user attempts to input a character string used in a mail text using this character input function, the conventional telephone must depress an operation key as follows. In the character input mode (mode for realizing the character input function), the number of keys is limited.
For each telephone key such as "1", "2", etc., for example, in hiragana, "A line" (10 characters of A-O and な ら-ぉ), "Ka line" (or 5 characters) ... "AB
C, "DEF",... Are assigned, and predetermined characters in the open input mode, the katakana input mode, and the like are specified by the number of times the telephone key is pressed.

For example, when the user attempts to input "U" in the open input mode, the "1A" key is
By pressing the key twice, the characters "a" to "u" are circulated in the normal order, and the character "u" to be input is specified.

In the case of inputting "K" in the open input mode, the input mode change key is pressed to change to the half-width input mode, and the character to be input is pressed by pressing the "2" key once. Identify mosquitoes. Also, if you are trying to input a “ba” sound in the open input mode,
Press the “6” key once, and then press the “*” key (
The semi-voice point is assigned to the telephone key “*”. ) Is pressed to combine "ha" and "@" to specify the character "ba" to be input.

[0006] For example, in the case where an input including a number of "1" is performed, "1" is entered in the half-width input mode.
The character "1" is specified by pressing the "A" key once, pressing the input mode change key to change to the open input mode, and pressing the "5" key twice.

Furthermore, in the open input mode, for example, when a plurality of characters of the same line "Ai" are input,
Press the "1a" key once and press a key not related to character input once to determine "a" first, then press the "1a" key twice to enter By pressing the key without the key once, "I" is determined and then "1"
Press the "A" key three times, and press one key that is not
By pressing the key twice to determine “U”, the character “Ai” to be input is specified.

For example, when inputting the sentence "go to the dentist today", in the open input mode, each key is appropriately pressed to specify "go to the dentist" and then the conversion key is pressed. Or "Today,"
By depressing the conversion key for each of the words "Haishini" and "Go", it is converted to "Go to the dentist today".

[0009] A mail message or the like can be input by operating the operation keys.

[0010]

However, in the above-mentioned conventional portable telephone, a plurality of characters are assigned to each key (in the case of the "1A" key, in the open input mode, the above-mentioned "A" and "A") are assigned. 10 characters (maximum character type), and the characters are circulated in the normal order. For this reason,
For example, if you try to enter "U" and press the "1A" key four times by mistake and "E" is entered,
In order to correct this to "U", the "1A" key must be further depressed nine times so as to go from "E" to "U" in the forward order.

In addition, when inputting by switching between full-width and half-width, inputting voiced and semi-voiced voices which are deformations of phonetic characters, and inputting with mixed numbers, the input mode conversion key is frequently operated. There must be.

Further, when a plurality of characters on the same line are to be input, it is necessary to frequently operate a key which has no relation to the character to be input to determine the input character. Also, when inputting a sentence, if it is converted in one sentence, erroneous conversion of the segment break position is likely to occur, the number of times the conversion key is re-operated increases, and conversely, the conversion key When the key is pressed, the conversion accuracy is improved, but the conversion key must be frequently operated.

Therefore, in the conventional mobile phone, in order to reach a certain function or a character to be input by the user,
It is necessary to operate a plurality of keys or press one key many times, which makes the key operation of the user extremely complicated.

[0014] The present invention has been made in view of the above problems, and has as its object to provide a mobile phone in which user operations are simplified.

[0015]

A portable telephone according to the present invention comprises:
Input means having an operation key capable of two-step operation, processing means for performing processing corresponding to each step of operation based on operation of the operation key, and display means for displaying a processing result of the processing means Have.

According to the present invention, there is no need to separately provide operation keys for switching functions and performing different processes.
By performing the two-step operation on the same operation key, processing corresponding to each step can be realized, and it is not necessary to operate another key to switch the function as in the related art, and the operability is improved.

In one embodiment of the present invention, the two-step operation is divided into two steps, a weak pressing operation and a strong pressing operation, according to the degree of pressing of the operation key.

According to the present invention, it is possible to execute different processing by changing the function depending on whether the operation key is pressed lightly or strongly.

In another embodiment of the present invention, the processing means, in response to the operation of one of the two steps on the same operation key, converts a plurality of characters assigned to the operation key in the forward direction. The cyclic processing is performed in the arrangement order, and the cyclic processing is performed in the arrangement order opposite to the forward direction according to the operation of the other stage.

According to the present invention, a desired character is input by repeatedly performing one-stage operation on an operation key to which a plurality of characters are assigned, so as to cycle through the plurality of characters in the forward arrangement order. When performing the operation in the forward direction due to erroneous operation, by performing the operation of the other stage, by circulating in the reverse arrangement order, compared with the conventional example that can only traverse in the forward direction, A desired character can be input by an operation.

In a preferred embodiment of the present invention, the processing means performs the same operation key as the character input operation key that has been operated in one of the two stages, and performs the operation in the other stage. By doing so, the input character is switched to full-width or half-width.

According to the present invention, a character is input by operating the operation key for character input in one stage.
Further, by performing the operation at the other stage, the input character can be switched to full-width or half-width, so that the input mode conversion key different from the character input operation key is required for full-width / half-width switching. There is no need to operate such as.

In a further preferred aspect of the present invention, the processing means responds to the operation of the other operation on the same operation key as the character input operation key operated in one of the two operations. , The input phonetic characters are transformed.

Here, the phonetic character transformation processing refers to conversion processing into mutable sounds, semi-sounding sounds, prompting sounds, relentless sounds, and the like.

According to the present invention, a character is input by operating the operation key for character input in one stage.
By performing the operation at the other stage, the input phonograms are transformed and converted into voiced sound, semi-voiced sound, prompting sound, muted sound, etc. In addition, there is no need to operate a “*” key or the like different from the operation keys for character input.

In another embodiment of the present invention, when one of the two steps is performed on an operation key, the processing means performs the operation in accordance with a set input mode. A character corresponding to a key operation is recognized and processed as an input character, and when the operation key is operated at the other stage, a character representing the number assigned to the operation key is used as an input character. The recognition processing is performed.

According to the present invention, when a character representing a number, that is, an input in which a number is mixed is performed, one-stage operation is performed on the operation key to which the number is assigned, so that the input mode is set. The corresponding character, for example, hiragana, katakana, etc., is processed as an input character, and by performing the other-stage operation on the operation key, a number is processed as an input character. There is no need to operate the input mode conversion key or the like.

In still another embodiment of the present invention,
When one of the two steps is operated on the same operation key to which a plurality of characters are assigned, the processing means sequentially converts the plurality of characters into input characters in accordance with the number of operations. If an operation at the other stage is performed on the operation key, a character corresponding to the operation is finally recognized as an input character.

According to the present invention, a plurality of characters, for example,
Repeat the operation at one stage for the operation keys to which multiple characters such as "A, I, U, E, O" on the "A" line are assigned, and select the characters on the line in order. And
By performing the other-stage operation on the operation key, the input character can be finally determined, and when inputting a plurality of characters on the same line, as in the related art, There is no need to frequently operate irrelevant keys.

[0030] In a preferred embodiment of the present invention, there is provided a conversion dictionary means for converting a sentence based on an input character, wherein the processing means is adapted to perform the operation when one of the two steps is performed. The input character is recognized in response to the operation, and when the operation of the other stage is performed, the position of the character corresponding to the operation is recognized as a sentence break position, and the operation is responded to the operation of the operation key for converting the text. do it,
A conversion process into a sentence is performed by using the conversion dictionary means, using the delimiter position as a delimiter.

According to the present invention, the input character is recognized by the operation of one stage, and the position of the character corresponding to the operation is recognized by the operation of the other stage as the sentence separation position, and the conversion dictionary means is recognized. Since the conversion process used is performed, it is possible to input the text separation position at the same time as the character input using the character input operation keys. There is no need to operate the conversion key.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the mobile phone according to the present invention will be described below with reference to the drawings.

(First Embodiment) FIG. 1 is a configuration diagram of a mobile phone according to a first embodiment of the present invention.

The portable telephone 1 has a radio section, a modem section,
TDMA processing unit, D / A / A / D conversion unit, audio processing unit,
A known transmitting / receiving unit 10 including a speaker, a microphone, and the like;
An input unit 20 and a display unit 30 arranged on the surface of the fuselage;
A conversion dictionary unit 40 and a control unit 50 as processing means for performing various processes such as a recognition process on input characters are provided.

The conversion dictionary unit 40 is composed of a memory, and stores in advance a character string corresponding to a reading character in addition to one character such as hiragana, katakana, alphanumeric characters, symbols, kanji, etc. in the order of the Japanese syllabary. .

FIG. 2 is an external view of the portable telephone 1. As shown in FIG.

On the outer surface of the mobile phone 1, a display unit 30 is provided.
An input unit 20 is provided.

The display unit 30 is composed of a liquid crystal display or the like, and displays characters and the like as operation results under the control of the control unit 50.

The input unit 20 includes operation keys 21, 22, 2,
3, 24, 25, etc., received key operation by the user,
Notify the control unit 50. The repetition key 21 is a multi-function operation key used for setting input modes such as hiragana, katakana, and alphanumeric characters, converting kana to kanji, and moving a cursor position. The operation key 22 is a two-stage operation type telephone key, and "1", "2",...
Line, “ka” line,…, “wa” line characters, “ABC”,
Alphanumeric symbols such as “DEF” are assigned. The “↓” key 23 is a scroll key for sequential forwarding,
The “↑” key 24 is a backward scroll key. The operation key 25 is a confirmation key.

Next, each configuration of the operation key 22 and the operation when the operation key 22 is pressed will be described with reference to the sectional view of FIG.

Each of the operation keys 22 is, for example,
A two-stage switch having the same configuration as a known switch disclosed in Japanese Patent Application Laid-Open No. H11-232962, comprising a cover 201 and a movable contact 203 having a disk portion 203A.
And peripheral fixed contacts 205A and 205B and a central fixed contact 206.

Opening 2 of cover 201 by fingertip 200
When the disc portion 203A of the movable contact 203 is pressed from 01A via the sheet 202, the disc portion 203A remains spherical and the connecting portion 204 first bends as shown in FIG. , The disk portion 203A faces in the horizontal direction, and its outer periphery has two peripheral fixed contacts 205A, 205A.
5B and the two peripheral fixed contacts 205A.
And 205B are short-circuited and turned on as a first switch.

When the disk 203A is further pressed down with the fingertip 200 from this state, as shown in FIG. 3 (b), the disk 203A is inverted to a downwardly swelling state with moderation. Center part 203 of disk part 203A
Aa contacts the central fixed contact 206 to electrically short-circuit between the peripheral fixed contacts 205A and 205B, which are short-circuited as the first switches, and the central fixed contact 206,
The second switch is turned on.

Thereafter, the disk portion 203A by the fingertip 200
When the pressing force is released, first, the disk portion 203A is restored to an upwardly projecting spherical state by its elastic restoring force, so that the center portion 203Aa is separated from the center fixed contact 206 and the second switch is turned off ( Returning to the state shown in FIG. 3A), the connecting portion 204 returns to the original upwardly inclined state, so that the outer periphery of the disk portion 203A separates from at least one of the two peripheral fixed contacts 205A and 205B. The first switch also returns to the off state.

The control unit 50 includes a ROM storing a control program, a working RAM, various counters,
It has a PU and the like, and integrally controls the transmission / reception unit 10, the input unit 20, the display unit 30, and the conversion dictionary unit 40 of the mobile phone 1. Note that, of the control of the control unit 50, only the control unique to the present embodiment will be described, and the description of the transmission / reception control of the telephone 1 and the like will be omitted.

When the control unit 50 receives a notification from the input unit 20 that an input mode or a key such as the operation key 22 has been pressed, it determines which key has been pressed. If this notification is a press notification of each telephone key of the operation keys 22, it is determined whether the key is lightly pressed (also called "normal operation") or strongly pressed (also called "special operation"). It counts whether or not the pressing operation has been performed twice. The determination of whether the switch is weakly pressed or strongly pressed is based on whether only the first switch is turned on or whether the first and second switches are connected.
Is determined by the conduction of the switch.

Then, when it is determined that the telephone key is pressed lightly, a character in which the maximum character type is circulated in the normal order in accordance with the number of presses is obtained from the conversion dictionary unit 40.
For example, in the open input mode, the user operates the input unit 2
When the "1" key is weakly pressed from "0", the control unit 50 determines "a" → "i" → "u" → "e" →
“O” → “ぁ” → “ぃ” → “ぅ” → “ぇ” → “ぉ” →
The characters that are circulated in the normal order, such as “A” →…, are acquired.

On the other hand, when it is determined that the character is strongly pressed, a character obtained by circulating in reverse order between the maximum character types is acquired from the conversion dictionary unit 40 based on the control program. For example, when the “1” key is pressed strongly, the control unit 50 outputs “A” → “ぉ” → “ぇ” → “ぅ” →
「ぃ」 → 「ぁ」 → 「お」 → 「え」 → 「う」 → 「い」 →
Characters that are circulated in reverse order, such as “A” →, are acquired from the dictionary unit 40. Then, the acquired characters are displayed on the display unit 30.

As described above, if each operation key 22 is a two-stage switch, and a function of forward patrolling with a weak press and a function of reverse patrolling with a strong push are assigned, for example, when "e" is input, "1" is input. Even if the user makes five incorrect operations of passing the "A" key to "O", the user can easily reach "E" by one operation by pressing the "1A" key once. Further, a function for supplementing the normal operation by the special operation can be realized with one key without providing an additional operation key, and the operator can intuitively understand the operation method.

Next, the operation of the control unit 50 according to the first embodiment will be described with reference to the flowchart of FIG.

First, the control unit 50 determines whether the operation key 22 has been pressed (step S101). Operation keys 22
If no is pressed, other processing is executed (step S
102), waiting for the operation key 22 to be operated. When the operation key 22 is pressed, the operation key 22 is acquired (step S103), and the maximum character type assigned to the operation key 22 (if the key is the “1A” key, 10 characters as described above) ) Is stored in the work RAM (step S10).
4) It is determined whether the pressed operation key 22 is the same operation key as the previous operation key (step S105). As a result of the determination, if the same operation key is not used, the forward and backward cycling of the maximum character type is not necessary. Therefore, the counter is initialized to “0” (step S106), and the process proceeds to step S107, where the same operation key is used. If there is, the process skips step S106 and proceeds to step S107 to determine whether the operation key is lightly pressed (normal operation) or strongly pressed (special operation).

If the result of the determination is that the switch is lightly pressed, the count value of the counter is incremented by "1" (step S10).
8) It is determined whether the count value is the same as the maximum character type (step S109). If the number is the same, "0" is set to the count value of the counter (step S110), and then the process proceeds to step S111. If the number does not reach the maximum number of character types, step S110 is skipped and step S1 is performed.
The process proceeds to step S11, where the character at the counter position is acquired from the conversion dictionary unit 40 (step S111), and the character is displayed on the display unit 30 (step S112). By repeating this process, characters that have been circulated in the normal order according to the number of times the operation key 22 has been pressed can be acquired from the conversion dictionary unit 40, and the acquired characters can be displayed on the display unit 30.

On the other hand, if the result of determination in step S107 is that the key is pressed strongly, the count value of the counter is decremented by "1" (step S121), and it is determined whether the count value is negative (step S122). If it is negative, the count value of the counter is set to "1" from the maximum number of character types.
After the value is decremented (step S123), the process proceeds to step S111, and if not negative, the process proceeds to step S110.
Skip to step S111. Then, the character at the counter position is obtained from the conversion dictionary unit 40 (step S111), and the character is displayed on the display unit 30 (step S112). By repeating this process, the characters circulated in reverse order according to the number of times the operation key 22 is pressed can be acquired from the conversion dictionary unit 40 and displayed on the display unit 30.

In this embodiment, each time the power is pressed strongly, the circuit travels in the opposite direction. However, as another embodiment of the present invention, once the power is pressed strongly, the circuit travels in the reverse direction even if the light pressure is applied. Alternatively, by being strongly pressed again, it is possible to return to patrol in the forward direction.

(Second Embodiment) Next, a mobile phone according to a second embodiment will be described. It should be noted that only the processing of the control unit 50 is different from that of the mobile phone of the first embodiment, so only the control unique to the present embodiment will be described, and the other description will be omitted.

The control unit 50 according to the second embodiment notifies the input character type information (input mode) from the input unit 20,
A notification of which operation key 22 has been pressed is received from the input unit 20, and it is determined whether each operation key 22 is weakly or strongly pressed. Then, when the input character type information is "hirakana input mode", when the same operation key 22 in which "hirakana" is input is pressed more strongly, the key is changed to the same kana character "full-width katakana". Further, when the same operation key 22 is pressed more strongly, the operation key 22 is changed to “half-width katakana”. For example, in the open input mode, when the "2 or" key is pressed lightly, "?" Is input, but when the same "2 or" key is pressed further, "?" Is input, and When pressed strongly, "K" is input.

When the input character type information is "numeric input mode", the same operation key
When "2" is pressed more strongly, it is changed to "full-width numeral" of the same numeral character. For example, when the "1" key is weakly pressed, a half-width "1" is input, and when the "1" key is further strongly pressed, a full-width "1" is input.

Further, when the input character type information is "alphabet input mode", the same operation key 2 in which "half-width alphabet" is input.
When 2 is pressed more strongly, the same alphabetic character is changed to "full-width alphabetic character". For example, in the alphabet input mode, when the "1" key is weakly pressed, a half-width "a" is input. When the same "1" key is further pressed, a full-width "a" is input.

Thus, without changing the character type, full-width /
Since a sentence in which half-width characters are mixed can be easily input by a simple operation, the input efficiency can be remarkably improved.

Next, the control unit 50 according to the second embodiment
Will be described with reference to the flowchart of FIG. For convenience of explanation, the description will be made assuming that the input character type information is “alphabet input mode” and that “half-width alphabet” is initially input.

First, the control unit 50 waits until the operation key 22 is pressed (step S201). When the operation key 22 is pressed, it is determined whether the pressed operation key 22 is the same operation key as the previous operation key (step S202). If the result of the determination is that the operation keys are not the same, full-width / half-width conversion is not necessary, so the counter is initialized to “0” (step S2).
03) Then, after temporarily outputting the output character (Step S204), the process proceeds to Step S205. Step S
In step 202, if the operation keys are the same, step S20
3. The process skips S204 and proceeds to step S205.

In step S205, a character in the current input mode corresponding to the pressed operation key, that is, a half-width alphabet is temporarily output according to the count value of the counter.
Next, it is determined whether or not the operation key 22 has been released (step S206).

When the operation key 22 is released, the count value of the counter is incremented by "1" (step S20).
7) It is determined whether or not the character input has been completed (step S2)
08), the process returns to step S201 until the character input ends. On the other hand, as a result of the determination, if the operation key 22 is pressed, it is determined whether or not the operation of the operation key 22 is strongly pressed (step S211). The output characters are converted to full-width characters and fixedly output (step S212), and the count value of the counter is cleared to "0" (step S213).
Wait until the operation key 22 is strongly pressed (step S2).
14) After the strong press ends, the process proceeds to step S208.

By repeating such processing, a half-width numeral can be converted to a full-width by a simple operation of strongly pressing the same operation key 22.

The case where the input character type information is “English character input mode” has been described.
In the case of, the same operation key 22 in which "hirakana" is input
Is pressed more strongly, or in the case of the “number input mode”, the same operation key 22 in which the “half-width numeral” is input is
Even when the button is pressed more strongly, full-width / half-width conversion can be performed with a simple operation by the same processing as the processing in FIG.

(Embodiment 3) Next, a mobile phone according to Embodiment 3 will be described. It should be noted that since only the processing of the control unit 50 is different from that of the mobile phone of the second embodiment, only the control unique to the present embodiment will be described, and the other description will be omitted.

The control unit 50 according to the third embodiment notifies the input character type information (input mode) from the input unit 20,
This embodiment is similar to the second embodiment in that a notification of which operation key 22 has been pressed is received from the input unit 20 and whether each operation key 22 is weakly pressed or strongly pressed is determined. In 3, when the input character type information is “hirakana input mode” or “katakana input mode”, when the same key with “kana” input is pressed more strongly from the input unit, The difference is that the phonetic character transformation process is performed, that is, the same kana character is changed to changeable voiced sound / semi-voiced sound / promotion sound / resonant sound. For this reason, in the flowchart shown in FIG. 6 of the embodiment, step S231 is processed instead of processing step S212 in FIG.

In this step S231, every time the character tentatively output in step S205 is pressed strongly, a changeable voiced sound / semi-voiced sound / promotion sound / consonant sound conversion process is performed. If the character being output is "ha", every time the character is strongly pressed, "ba",
If it is converted to “ぱ” and the character being output is “tsu”, it is converted to “zu” or “tsu” every time the character is strongly pressed, or it is temporarily output. If the character is "yo", when it is pressed strongly, it is converted to "yo".

(Embodiment 4) Next, a mobile phone according to Embodiment 4 will be described. Embodiments 2 and 3
Since only the processing of the control unit 50 is different from that of the first embodiment, only the control specific to the present embodiment will be described, and other description will be omitted.

The control unit 50 according to the fourth embodiment transmits a notification of input character type information (input mode) from the input unit 20,
This embodiment is similar to the second embodiment in that a notification of which operation key 22 has been pressed is received from the input unit 20 and whether each operation key 22 is weakly pressed or strongly pressed is determined. 4, when the input character type information is "hirakana input mode", "katakana input mode", or "alphabet character input mode", when information that the operation key 22 is weakly pressed is input from the input unit, When information of a mode is input and strongly pressed information can be input from the input unit, it is changed to a half-width numeral assigned to the same operation key. For this reason,
In the flowchart shown in FIG. 7 of this embodiment, FIG.
Step S241, instead of the processing step S212
S242 is processed.

In step S241, all the characters temporarily output in step S205 are determined, and in step S242, the half-width numerals assigned to the operation keys are determined.

Such conversion using a mixture of numbers can be converted into half-width numbers by a simple operation without changing the input mode. For example. If you want to enter "1",
"1" is input by strongly pressing the "A1" key,
By pressing the "na5" key twice weakly, "ni" is input.

Accordingly, the number of times the mode conversion key is pressed for inputting a sentence containing numbers is greatly reduced, so that the input efficiency is greatly improved.

(Fifth Embodiment) Next, a mobile phone according to a fifth embodiment will be described. Embodiments 1 to 4
Only the processing of the control unit 50 differs from that of
Only control specific to the present embodiment will be described, and other description will be omitted.

The control unit 50 according to the fifth embodiment notifies the input character type information (input mode) from the input unit 20,
A notification of which operation key 22 has been pressed is received from the input unit 20, and it is determined whether each operation key 22 is weakly or strongly pressed. Then, when the input character type information is "hirakana input mode", when the same operation key 22 in which "hirakana" is input is further pressed down, it is regarded as final character determination and the cursor is moved to the next character display position. Is to be moved. For example, when inputting a plurality of hiragana characters on the same line as in "Ai", the "A" key is set to 1
Press "A" key once to confirm "A", lightly press "A" key once to confirm "I", and press hard once to confirm "A"
By pressing the key twice lightly and once strongly, "U" is determined.

Next, the control unit 50 according to the fifth embodiment
Will be described with reference to the flowchart of FIG. Note that, for convenience of description, at the start of the flow, a description will be given assuming that a character that has been input before is determined.

First, the control unit 50 waits until the operation key 22 is pressed (step S301). When the operation key 22 is pressed, it is determined whether the conversion key is pressed (step S302). If the conversion key is not pressed, it is determined whether the operation key 22 is pressed strongly (step S30).
3). If it is lightly pressed (N in step S303), characters are input and displayed at the cursor position on the display unit 30 (step S304), and the process returns to step S301. On the other hand, if it is a strong press, the cursor position on the display unit 30 is moved to the next character display position, assuming that the final character is determined (step S305), and the process returns to step S301.
By repeating such a process, it is possible to perform “a” with a simple operation without operating keys that are not related to character input.
You can enter multiple hiragana characters on the same line.

If the conversion key is depressed in step S302, a sentence in which the conversion result of the input reading character has the highest evaluation is read from conversion dictionary unit 40 and the document is displayed on display unit 30 (step S306). .

Therefore, according to the invention of this embodiment, there is no need to operate keys that are not related to the character input itself, and the number of operations by hiragana input can be greatly reduced.

Embodiment 6 Next, a mobile phone according to Embodiment 6 will be described. Note that, only the processing of the control unit 50 is different from that of the fifth embodiment, so only the control unique to the present embodiment will be described, and the other description will be omitted.

The control section 50 according to this embodiment regards the operation key 22 as a break of a phrase up to the character that is input when the operation key 22 is strongly pressed, saves information on the break position of the phrase, and performs a light press. Is not considered to be a segment break.

For example, when "Hi go to today" is input in hiragana and converted by the conversion operation into a sentence "go to the dentist today", the "2" key is lightly pressed twice to enter "ki". Enter "yo" by pressing the "8 or" key six times lightly, and enter "u" as the segment break position by pressing the "1a" key twice and pressing hard once. , "6 wa" key is pressed once to input "ha", ..., "5 na" key is pressed once to 1
Press the key twice to input "Ni" as a segment break position,..., Press the "2 or 3" key three times to input "KU", and finally press the "Convert" key.

In this case, the control unit 50 searches the conversion dictionary unit 40 from the conversion dictionary unit 40 based on the sentences for each of the clause breaks of “Today”, “Haishani”, and “Iku”. In addition, highly accurate conversion can be realized.

Next, the control unit 50 according to the sixth embodiment
Will be described with reference to the flowchart of FIG. Note that, only the processing of the control unit 50 is different from that of the fifth embodiment, so only the control unique to the present embodiment will be described.
Other description is omitted.

The control section 50 according to this embodiment regards the operation key 22 as being strongly pressed in step S303 as a segment break position, and stores information on the segment break position (step S311). Step S30
Go to 5. On the other hand, if it is lightly pressed, it is determined that it is not a segment break, and the process proceeds to step S304. When the conversion key is pressed, the conversion dictionary unit 40 is searched based on the information on the segment break positions stored in step S311 (step S312).
Proceed to 306.

Therefore, according to the invention of this embodiment, unlike the related art, a conversion key different from an operation key for character input is operated at a text break position to frequently perform conversion processing. However, conversion can be performed with high accuracy.

In this embodiment, the position after the strongly pressed character is set as the separation position, but it is needless to say that the position before the strongly pressed character may be set as the separation position.

(Other Embodiments) In the above embodiment, a two-stage operation type switch is used only for the operation key 22, but as a modified example, the scroll keys 23 and An operation type switch, and the display unit 30
The operation of scrolling the data displayed in the field may be performed by performing a scroll operation at a normal speed with a light press, and a high-speed scroll operation of one screen with a strong press. As a result, when browsing a large amount of data or a long mail, not only the effect of being able to reach the target data more comfortably, but also the operation for assisting the specific function is assigned to one key. There is an effect that the user does not need to carry out a large learning, can intuitively understand the operation method, and can easily use differently.

As another embodiment of the present invention, the processing contents for the light pressing and the strong pressing in the above embodiment may be exchanged.

As another embodiment of the present invention, a configuration having both the functions of the above-described embodiments is provided, and the function of any of the embodiments can be selected by a separately provided key or the like. Good.

[0091]

As described above, according to the portable telephone according to the present invention, a separate operation key is not provided for switching functions and performing different processes. The corresponding different processing can be realized, the operation becomes extremely simple, and the complicated operation of operating another operation key for switching the function can be avoided.
