Embodiment 1 Next, an embodiment of the present invention will be described in detail with reference to the drawings.
As shown in FIG. 1, the system for executing the kana-kanji automatic conversion method according to the present embodiment includes an input / output device 1, a pen pressure sensing device 2, a character recognition device 3, a data processing unit 4, and a timer 5. The data processing unit 4 is a data processing device 4
1 and a dictionary storage unit 42, and the timer 5 includes a word input timer 51 and an interval timer 52.

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

The data processing unit 4 activates the word input timer 51 at the same time as the input is started. When the word input timer 51 has reached the predetermined time T and enters an input waiting state, the interval timer 52 is operated. When the interval timer 52 reaches a 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 pen pressure sensing device 2 and the character recognition device 3.

As shown in FIG. 1, the pen pressure sensing device 2 always detects the pen pressure at the time of input with a pen, and transmits the pen pressure data of a level from 0 to 7 divided by a threshold value to the data control unit 4. I do. When the data control unit 4 receives a change in the pen pressure level from 0 to a positive level and character data from the character recognition device 3, it determines that the input has started.

The flow from the start of input to the end of input is shown in the flowchart of FIG. Word input timer 51 as soon as input starts
To start time measurement (step A1). A time during which the user can think of one word is assigned to the time T of the word input timer 51. T is approximately equal to the time required to think and input a character for one word.
After the word input timer 51 reaches the predetermined time T (step A2), the interval timer 52 is operated each time the pen pressure level becomes 0 and the input wait state (step A3) is reached. A minute 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 phrase 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 a screen. After the kanji conversion, if no input is received (step A6), all the processes are terminated.
FIG. 11 shows an example in the case where "Last is very bad" is input.

When the kana character string "Sakuji tsu wa" is input, the word input timer 51 for measuring the time T together with the input of "Saku" is started as described above. When the time T elapses before the input of (1) starts and the apparatus enters a state of waiting for input, the interval timer 52 operates.

At this time, if the input of "T" is given before time t, the kanji conversion is not performed and the interval timer 52 is reset. As soon as the input of "T" is completed and the input disappears, the interval timer 52 operates again. In this example, since the time t has not elapsed before the input of “ha”, the conversion is not performed by “fortune”,
If the input to "wa" is delayed, it is converted to "yesterday".

In the details of the times T and t, it is assumed that T determines the time required for thinking about one word by taking statistics or the like. Particles are not considered to take time in their thinking and are not included in time T. This is time t
It is thought that you can think below. It is assumed that the time t is the same as the time T when the statistics are obtained. This means a small amount of time before the thinking of the particle and the thinking of the next word.

Since the times T and t vary among individuals, it is assumed that the time T and t can be user-defined at the time of initial setting. Also,
Basically, like "Sakujitsu" and "Taihen",
Similar processing is performed for any combination.

The "time to be able to think" is defined as "words"
"Time to image (word)" and "time to think" mean "time to think about the connection from one word to the next."

The embodiment according to the present invention is based on the fact that the time required to come up with one word and the time of familiar handwriting input will be approximately equal, and one word is drawn with a pen. There seems to be individual differences in writing, but I think that the time to write a word with a pen is almost constant regardless of the length of the word.

It should be noted that if only the interval timer 52 is used, the kana-kanji conversion is performed even when it is not clear whether or not another word should be used after the first character of the word is input.
Therefore, to cover that point, the word input timer 51
Becomes indispensable.

Since the kana-kanji automatic conversion method according to the first embodiment is configured as described above, the following effects can be obtained. The automatic processing of Kana-Kanji conversion eliminates the need to press the conversion key for converting Kana-input characters to Kanji or the tapping of the conversion key on the panel with a pen, thereby speeding up document input. it can.

(Embodiment 2) The structure of the kana-kanji automatic conversion method according to the present embodiment is the same as that of the first embodiment.
A pen pressure change is used as a means for determining a segment break. For example, if the pen pressure level is set to a minimum of 0 and a maximum of 7, there is a difference depending on the user, but when writing a paragraph or finishing writing the last character of one word, the pen pressure level is from 4 to 7 or level. As in the case of the level 4 to the level 1, a large change occurs in the pen pressure as compared with the case of inputting other characters.

The flow from the start to the end of the 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 a predetermined time T has elapsed, a change in the pen pressure level is detected (step B1). This change rate is transmitted to the data processing device 41. If the rate of change is large, the input character string is determined as a phrase (step B2), and kanji conversion processing is performed (step A5). After the conversion process,
If there is no input, all processing ends.

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

(Embodiment 3) The kana-kanji automatic conversion method according to the present embodiment employs an input / output device 1, a pen pressure sensing device 2, a character recognition device 3, a data processing unit 4 'and a timer 5 as shown in FIG. It is schematically constituted by The data processing unit 4 ′ includes a data processing device 41, a dictionary storage unit 42, and a punctuation mark storage unit 4.
3, the timer 5 includes a word input timer 51 and an interval timer 52.

Punctuation input is used as a means for determining a phrase break. Since the punctuation mark means a paragraph break, the kanji conversion processing is performed at the same time as receiving the input of the punctuation mark regardless of whether the predetermined time T has elapsed.

The process from the start to the end of the input is shown in the flowchart of FIG. Processing flow A1, A2, A by time
In A3, A4, A5 and A6, the same processing as in the first embodiment is performed.

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

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

(Embodiment 4) As shown in FIG. 7, when a pen is rested after inputting a phrase, a pen point is placed at the lower right corner of the input area to determine a break, and kanji conversion processing is performed. As a result, even if the input of one word is completed within a predetermined time T or less, kanji conversion is possible.

The flow from the start to the end of the input is shown in the flowchart of FIG. Processing flow A1, A2, A by time
In A3, A4, A5 and A6, the same processing as in the first embodiment is performed. After the kana is input in the input area, if the pen tip is placed at the lower right corner of the same area, the input character string is converted into kanji as a phrase. When receiving the first character input, the word input timer 51 (step A1) operates. When the pen pressure is detected in the lower right corner of the input area (step D1), the input character string is converted into kanji.

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

(Embodiment 5) The automatic kana-kanji conversion method according to the present embodiment is roughly composed of an input / output device 1 ', a data processing unit 4, and a timer 5, as shown in FIG. The input / output device 1 'includes an input device keyboard 11 and an output device 12, the data processing unit 4 includes a data processing device 41 and a dictionary storage unit 42, and the timer 5 includes a word input timer 51.
And an 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 from the start of input to the end of input is shown in the flowchart of FIG. Processing flows A1, A2, and
In A3, A4, A5, and A6, the same processing as in the first embodiment is performed.

When the data processing section 4 receives the input data, the word input timer 51 is activated at the same time. The data processing unit 4 converts the input alphabet into kana as needed (step E1).

After a lapse of a predetermined time T (step A2), the interval timer 52 is operated each time the alphabet is converted to kana (step A3). The predetermined time t is from the completion of kana conversion to the completion time of kana conversion of the next character.
Thus, even if the user hits the key after inputting the phrase and before inputting the next character (kana), it is possible to prevent a meaningless conversion process from being performed.

The last input alphabet is converted to kana (step E2), and the input character string is converted to kanji (step A5) at the same time as the specified time t has elapsed (step A4).

Since the automatic kana-kanji 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, the following will be described. It has the following effects. 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 the meaningless conversion process is not performed, so that a smooth document input operation can be performed.
