BEST MODE FOR CARRYING OUT THE INVENTION (Embodiment 1) Next, an embodiment of the present invention will be described in detail with reference to the drawings.
As shown in FIG. 1, a system for executing the kana-kanji automatic conversion method according to the present embodiment is roughly configured by an input / output device 1, a writing pressure sensing device 2, a character recognition device 3, a data processing unit 4, and a timer 5. The data processing unit 4 is the data processing device 4
1 and a dictionary storage unit 42, and the timer 5 is composed of a word input timer 51 and an interval timer 52.

As shown in FIG. 2, the input / output device 1 is composed of a panel and a stylus pen, and the panel also has a character display function. The writing pressure sensing device 2 detects writing pressure applied to the panel by the stylus pen. The character recognition device 3 recognizes the coordinate information input to the panel as a character.

In the data processing unit 4, the word input timer 51 is activated at the same time when the input is started. When the word input timer 51 reaches the predetermined time T and enters the input waiting state, the interval timer 52 is activated. When the interval timer 52 reaches the minute predetermined time t, the data processing device converts the transferred character string into kanji data and transfers it to the input / output device.

Next, the operation of the kana-kanji automatic conversion method will be described. As shown in FIG. 2, when a character is input from the input / output device 1, the input data is transmitted to the writing pressure sensing device 2 and the character recognition device 3.

As shown in FIG. 1, the pen pressure sensing device 2 constantly detects the pen pressure at the time of input by the pen, and transmits the pen pressure data of levels 0 to 7 divided by the threshold to the data control unit 4. To do. The data control unit 4 determines that the input has started when the writing pressure level changes from 0 to a positive level and the character data from the character recognition device 3 is received.

The process from the start of input to the end of input is shown in the flowchart of FIG. Word input timer 51 when input starts
To start time measurement (step A1). The time T of the word input timer 51 is assigned a time for the user to think of one word. T is approximately equal to the time required for thinking of one word and inputting characters.
After the word input timer 51 reaches the predetermined time T (step A2), the interval timer 52 is activated each time the writing pressure level becomes 0 and the input waiting state is entered (step A3). A small amount of time until the user thinks of the next word is assigned to the time t of the interval timer 52.
When the interval timer 52 reaches t (step A
4) The input character string is regarded as a segment break, and the input kana character string is subjected to Kanji conversion processing in the data processing unit 41 (step A5). The kanji-converted data is transmitted to the input / output device 1 and displayed on the screen. If no input is accepted after conversion of Chinese characters (step A6), all the processes are terminated.
FIG. 11 shows an example of the case where “Sakujitsuhataihen” is input.

When inputting the kana character string "Sakujitsuwa", as described above, the word input timer 51 for measuring the time T is started together with the input of "Sa", and the input of the phrase "Sakujitsuwa" is confusing. When the time T elapses before the input is started and the input standby state is entered, the interval timer 52 operates.

At this time, if the input of "tsu" is given by the time t, the kanji conversion is not performed and the interval timer 52 is reset. At the same time as the input of "one" is completed and the input is removed, the interval timer 52 is activated again. In this example, since the time t has not elapsed until "ha" is input, it is not converted by "sakujitsu", but
If the input up to "ha" is delayed, it will be converted to "yesterday".

Further, in the details of the times T and t, it is assumed that T determines the time taken to think of one word by taking statistics. Particles are considered not to take time to think and are not included in time T. This is time t
The idea is that you can think below. As with T, the time taken for statistics is adopted as the time t. This means a small amount of time before starting to think about the particle and thinking about the next word.

Since the times T and t vary among individuals, they can be defined by the user at the time of initial setting. Also,
Basically, like the above "Sakujitsu" and "taihen",
The same process is performed for any combination.

"Thinking time" means "word
"Time to image (word)" and "time to think" mean "time to think of the connection from one word to the next".

The embodiment according to the present invention is based on the fact that the time it takes to come up with one word will be approximately the same as the time for handwriting input that is familiar, and one word can be written with a pen. Although it seems that there are individual differences in writing, I think that the time to write one word with a pen is almost constant regardless of the length of the word.

It should be noted that with the interval timer 52 alone, when inputting the first character of a word and wondering whether it should be changed to another word, kana-kanji conversion is performed, which causes inconvenience.
Therefore, in order to cover that point, the word input timer 51
Is essential.

Since the kana-kanji automatic conversion method according to the first embodiment is configured as described above, it has the following effects. The automatic processing of kana-kanji conversion eliminates the need to press the conversion key to convert kana input characters to kanji or tap the conversion key on the panel with a pen, enabling faster document input. it can.

(Second Embodiment) The structure of the kana-kanji automatic conversion method according to the present embodiment is the same as that of the first embodiment.
A change in writing pressure is used as a means of determining a phrase break. For example, if the writing pressure level is set to 0 or 7 at the maximum, it may vary depending on the user, but when finishing the punctuation or the last character of one word, the writing pressure level is changed from level 4 to level 7 or level. A significant change occurs in writing pressure from 4 to level 1 as compared to when other characters are input.

The process from the start of input to the end of input is shown in the flowchart of FIG. Processing flow A1, A2, A by time
3, A4, A5 and A6 are processed in the same manner as in the first embodiment.

After the elapse of the predetermined time T, the change in the writing pressure level is detected (step B1). This rate of change is transmitted to the data processing device 41. If the rate of change is large, the input character string is judged as a phrase (step B2), and Kanji conversion processing is performed (step A5). After being converted,
If there is no input, all processing ends.

Since the kana-kanji automatic conversion method according to the second embodiment is configured as described above, it has the following effects in addition to the effects of the first embodiment. Since the writing pressure change is used as a means for determining the phrase break, it is not necessary to separate the pen from the panel surface to set the writing pressure to "0" as a condition for waiting for input, and smooth document input work can be performed. it can.

(Embodiment 3) As shown in FIG. 5, the Kana-Kanji automatic conversion method according to the present embodiment includes an input / output device 1, a writing pressure sensing device 2, a character recognition device 3, a data processing unit 4 ', and a timer 5. It is roughly configured by. The data processing unit 4 ′ includes the data processing device 41, the dictionary storage unit 42, and the punctuation mark storage unit 4
3, the timer 5 is composed of a word input timer 51 and an interval timer 52.

Input of punctuation marks is used as a means for determining a phrase break. Since punctuation marks mean phrase breaks, regardless of whether or not a predetermined time T has passed, the input of punctuation marks is performed and the Chinese character conversion processing is performed at the same time.

The process from the start of input to the end of input is shown in the flowchart of FIG. Processing flow A1, A2, A by time
At 3, A4, A5 and A6, the same processing as in the first embodiment is performed.

When a character input is received, the word input timer 5
1 operates (step A1). When the punctuation mark is input (step C1), the character recognition device 3 transfers the data of the character string and the punctuation mark to the data processing unit 41. The data processing unit 41 divides the data into phrases and punctuation marks before the punctuation mark and performs conversion processing.

Since the kana-kanji automatic conversion method according to the third embodiment is configured as described above, it has the following effects in addition to the effects of the first and second embodiments. Since the input of punctuation marks is used as a means for determining the phrase break, an appropriate kana-kanji automatic conversion is performed and the document input work can be performed smoothly.

(Embodiment 4) As shown in FIG. 7, the pen point is determined at the lower right corner of the input area at the time of writing break after inputting a phrase, and it is determined to be a division, and the kanji conversion processing is performed. As a result, even if the input is a single-character word within a predetermined time T or less, the Kanji conversion can be performed.

The flow from the start of input to the end of input is shown in the flowchart of FIG. Processing flow A1, A2, A by time
At 3, A4, A5 and A6, the same processing as in the first embodiment is performed. After the kana is input in the input area, when the pen tip is placed in the lower right corner of the same area, the already input character string is converted into a kanji character. When the first character input is received, the word input timer 51 (step A1) is activated. When the pen pressure is detected at the lower right corner of the input area (step D1), the input character string is converted into kanji.

Since the kana-kanji automatic conversion method according to the fourth embodiment is configured as described above, it has the following effects in addition to the effects of the first, second and third embodiments. Since the writing pause operation is used as the means for determining the phrase break, the kana-kanji automatic conversion can be appropriately performed, and the smooth document input work can be performed.

(Fifth Embodiment) As shown in FIG. 9, the Kana-Kanji automatic changing method according to the present embodiment is roughly constituted by an input / output device 1 ', a data processing unit 4 and a timer 5. The input / output device 1 ′ is composed of an input device keyboard 11 and an output device 12, the data processing unit 4 is composed of a data processing device 41 and a dictionary storage unit 42, and the timer 5 is a word input timer 51.
And interval timer 52. The character data input from the input device (keyboard) 11 is transferred to the data processing unit 4, and the input data is transferred from the data processing unit 4 to the output device.

The flow chart from FIG. 10 from the input start to the input end is shown. Processing flow A1, A2, according to time
At A3, A4, A5, and A6, the same processing as in the first embodiment is performed.

At the same time when the data processing unit 4 receives the input data, the word input timer 51 is activated. The data processing unit 4 converts the input alphabet into kana at any time (step E1).

After the elapse of the predetermined time T (step A2), the interval timer 52 is activated each time the alphabet is converted into kana (step A3). The predetermined time t is from the completion of kana conversion to the completion time of kana conversion for the next character.
This prevents the meaningless conversion process from being applied even if the key is hit after the phrase is input and before the next character (kana) is input.

The last input alphabet is converted into kana (step E2), and at the same time when the specified time t elapses (step A4), the input character string is converted into kanji (step A5).

Since the kana-kanji automatic conversion method according to the fifth embodiment is configured as described above, in addition to the effects of the first, second, third and fourth embodiments, It has the effects listed. The alphabet input from the keyboard is converted at any time, and at the same time, the kana-kanji automatic conversion is performed based on the above setting, and meaningless conversion processing is not performed, so that a smooth document input operation can be performed.

The present invention is not limited to the above-mentioned embodiment, and the input means includes not only the voice input means but also all the input means which can apply the trigger for the automatic conversion of kana-kanji characters to the passage of time.
