Description of the Related Art Heretofore, various types of handwriting have been configured so that characters and the like are handwritten input from a character input area on a tablet using a pen or the like, and the handwriting of the handwritten input is recognized by a recognition processing unit. A character recognition device has been proposed.

[0003] By the way, the speed of the handwriting input of the user varies from person to person, and there are some people who have a high speed of handwriting input and some people who have a low speed of handwriting input. It is fully conceivable that an input is made.

In this regard, Japanese Patent Publication No. 3-40878 discloses a character extraction method. In such a character extraction method, after a character recognition process based on previously input stroke data is completed, a stroke by rewriting is added. If data is input, invalidate the result of character recognition performed up to that point, take in retouched input stroke data, add retouched stroke data to previous stroke data, and perform character recognition again Have been.

[0005]

However, in the character extracting method disclosed in Japanese Patent Publication No. 3-40878, the character re-recognition is performed by taking in additional stroke data input after the completion of character recognition. Such re-recognition is performed only when retouched stroke data is input in the same character input section (area), and unlimited input of rewritten stroke data is performed within the same character input area. Therefore, the input of the retouched stroke data is not permitted until the handwriting input is performed in another character input area.

Therefore, in the character extracting method,
Before performing handwriting input in another character input area adjacent to the same character input area, if the same area as the character input area where handwriting input has already been performed is accidentally touched with a pen or the like, As described above, as long as the character input area is within the same character input area, the retouching is allowed without any restriction, and an incorrect recognition result will be obtained when the character is re-recognized. As described above, the character extracting method disclosed in Japanese Patent Publication No. 3-40878 has a problem that character recognition cannot be performed with a good recognition rate due to erroneous recognition.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems. The present invention makes it possible to validate a retouched input input within a predetermined time after completion of recognition of a handwritten input character, and to input a retouched input after a predetermined time.

On the other hand, when it is determined that the pen is not touching the item on the layout screen L (S4: N
O) In S6, it is determined whether or not the pen touches the key area G. When it is determined that the pen has touched the key area G (S6: YES), the character input areas D,
A keyboard is displayed instead of E and F, and characters are input by a key input operation. Then, in S8, it is determined whether or not the key input operation has been completed, and when it has been completed (S8: Y
ES), the process returns to S3, and if not completed (S
8: NO), the process returns to S7.

When it is determined in S6 that the pen has not touched the key area G (S6: NO).
In step S9, it is determined whether the pen has touched the print area H. If it is determined that the pen has touched the print area H (S9: YES), the stamp of the stamp body 1 is printed in S10 in accordance with the punching data stored in the punching buffer 125 based on the character string data input so far. Face part 30
The character string is punctured. Thereafter, the process returns to S3. still,
If the area touched by the pen in S9 is not the print area H (S9: NO), another processing operation is performed (S11).

If it is determined in S4 that the pen has touched an item on the layout screen L (S4: YES), the process proceeds to S4.
Then, in S5, a cursor is displayed on the item touched by the pen. For example, in FIGS. 16 and 17, the cursor K is displayed at the item “company name”.

Following the above, handwriting input is performed as follows. In the following description, a case where a character is input by handwriting in the character input area D will be described for convenience. That is, in S12, one stroke (one stroke) is written in the character input area D with the pen. At this time, coordinate data for one stroke is acquired, with the starting point of one stroke being (X ₀ , Y ₀ ) and each point obtained by sampling one stroke being (X _n , Y _n ).

In the following S13, it is determined whether or not the next stroke has been rewritten during the predetermined time T ₁ second.
Here, the time T ₁ is determined in consideration of an interval between each stroke when a normal user performs handwriting input. Moreover, the determination of whether the next stroke is retouched, pen between T ₁ seconds after leaving the pen character input area D at the first stroke based on whether mentioned in the character input area D line Will be

If the next stroke is rewritten during the time T ₁ second (S13: YES), the flow returns to S12 to obtain the coordinate data of the retouched stroke for the stroke based on the retouch in the same manner as described above. Is done. In this way, by repeating the processing of S12 and S13, coordinate data is obtained for each stroke of one character.

If it is determined in S13 that the next stroke has not been rewritten during the time T ₁ second (S13: NO), the start point and the end point of each handwritten input stroke are set in the character input area D. (S14). Specifically, the X coordinate X ₀ of the starting point (X ₀ , Y ₀ ) of each stroke is 0 ≦ X ₀ ≦ 56, and the Y coordinate Y
₀ satisfies 0 ≦ Y ₀ ≦ 56, and the X coordinate X _n of the end point (X _n , Y _n ) of each stroke is 0 ≦ X _n ≦ 56, and the Y coordinate Y _n is 0 ≦ Y _n ≦ 56. It is determined whether they are satisfied.
If the determination in S14 is YES, that is, the start point and the end point of each handwritten input stroke are in the character input area D
If it exists in S1, to perform normal character recognition, S1
Move to 8.

On the other hand, if the determination in S14 is NO
In other words, if the start point and the end point of each stroke input by handwriting do not exist in the character input area D,
At 15, it is determined whether or not the end point of each stroke continuously exceeds the character input area D in the rightward or downward direction. Specifically, the X at the end point (X _n , Y _n ) of each stroke
Coordinate X _n is X _n > 56, or Y coordinate Y _n is Y _n > 56
Is determined to be satisfied. Here, it is generally determined whether or not the end point (handwriting) of each stroke is formed rightward or downward beyond the character input area D when the user performs handwriting input. This is because, in consideration of the fact that the input area hardly protrudes upward or to the left and input, it often protrudes to the right or downward.

If it is determined in S15 that the end point of each stroke does not continuously exceed the character input area D in the rightward or downward direction (S15: NO), the process proceeds to S18. On the other hand, when it is determined that the end point of each stroke continuously exceeds the character input area D in the rightward or downward direction (S15: YES), the start point of each stroke is set in the character input area D in S16. Is determined whether it exists. Specifically, the starting point of each stroke (X ₀ , Y ₀ )
It is determined whether the X coordinate X ₀ satisfies X ₀ ≧ 57 and the Y coordinate Y ₀ satisfies Y ₀ ≧ 57.

In S16, when the starting point of each stroke does not exist in character input area D (S16: YES)
To S18, and if the starting point of each stroke exists in the character input area D (S16: NO),
Move to 17.

Here, in S18, the range of the character input area D ((X, Y) = (1, 1) to (56, 56))
The normal character recognition is performed within the range of). After this S19
Move to In S17, the range of the character input area D is expanded in the rightward and downward directions, and the expanded range ((X, Y) = (1, 1) to (64, 6)
Character recognition is performed within the range of 4)). After this, S19
Move to

At this time, it is determined that the end point of each stroke continuously exceeds the character input area D rightward or downward (S15: YES), and the start point of each stroke is within the character input area D. If it is determined that there is (S1
6: NO), the process of enlarging the range of the character input area D rightward and downward in S17 is performed based on the handwriting itself formed in the enlarged range. This is performed under the same conditions as in the case where the handwriting input is normally performed so as to fit within the character input area for one character. Thus, even when the handwriting of the handwriting input is formed beyond the character input area D, the character can be recognized with a good recognition rate. For example, as shown in FIG. 17, the start point of the final stroke of the handwritten character “F” exists in the character input area D, and the end point protrudes rightward from the character input area D. The character input area D is enlarged rightward and downward to
The character becomes E, and the handwritten character "" is recognized in the enlarged character input area DE.

Here, in the enlarged character input area DE, the enlargement direction is limited to the right direction and the downward direction, and the enlargement range (amount) is a predetermined range ((X,
Y) = (1, 1) to (64, 64)). In this manner, the amount of expansion of the character input area D is not limited to an unlimited amount, but the amount of expansion of the character input area D is limited in consideration of the extent to which handwriting generally protrudes from the character input area D during handwriting input. This makes it easy to enlarge the character input area D.

The direction in which the handwriting protrudes from the handwriting input,
In addition, only the rightward direction and the downward direction of the character input area D are considered as the enlargement direction of the character input area D in S17. Thus, by taking into account the general tendency of the handwriting input by the user, a simple operation is possible. Only by performing the control process, it is possible to perform the character recognition of the handwriting protruding from the character input area D.

In S19, it is determined whether the character recognition processing has been completed. If it is determined in S19 that the character recognition processing has been completed (S19: YES), the recognition result in S20 corresponds to the RO corresponding to the model screen touched by the pen.
The image is displayed on the liquid crystal display 53 in a state in which the display format (attribute) stored in the table 123A of M112 is reflected. Specifically, since the name stamp is selected as the template screen, the layout screen L displays the company name after the handwritten input characters have been recognized, as shown in FIG. As shown in FIG. 19, the name after the handwritten input character has been recognized is displayed. Here, the company name is determined based on the display format stored in the table 123A of the ROM 112.
It can be seen that the character size is 32 points, the character decoration is gothic, the character direction is horizontal, the character arrangement is left aligned, and the character spacing is narrow (see FIG. 18). Similarly, for the name, based on the display format of the table 123A, the character size is 64 points, the character decoration is gothic, the character direction is horizontal, the character arrangement is uniform, and the character spacing is normal. (See FIG. 19). FIG. 18 is an explanatory diagram showing a layout screen after the handwriting input company name is recognized, and FIG.
FIG. 9 is an explanatory diagram showing a layout screen after the company name and the name input by handwriting have been recognized.

As described above, the handwritten input characters are displayed on the liquid crystal display 53 while reflecting the display format (attribute) stored in the table 123A of the ROM 112 corresponding to the model screen touched by the pen. The user can easily confirm the stamp surface state corresponding to the type of stamp to be created on the liquid crystal display 53 without performing complicated format settings.

[0074] Thereafter, in S21, another stroke is determined whether it has been retouched during the predetermined time T ₂ seconds. Here, the time T ₂ are, are set longer than the above-mentioned time T _1. Further, whether another stroke is retouched judgment, pen in front of the stroke between T ₂ seconds after the pen away from the character input area D based on whether mentioned in the character input area D line Will be

If another stroke is added during the time T ₂ seconds (S21: YES), the flow returns to S12 to acquire the coordinate data of the added stroke in the same manner as described above for the stroke based on the added stroke. Is done. Also, the time T
_When another stroke is not rewritten within ₂ seconds (S
21: NO), the retouching input performed after the elapse of the time T ₂ seconds in S22 is invalidated, and the character input areas DF and the character input areas DF displayed on the liquid crystal display 53 are displayed. Erase the characters that are In this manner, by erasing the character input area D and the like and the characters, it is possible to notify the user that re-recognition by rewriting becomes impossible.

As described above, if another retouching is performed during the time T ₂ seconds even after the recognition is completed in S19, the retouching is enabled and the handwriting input is enabled again to perform the re-recognition. In addition to this, since the retouching input performed after the lapse of the time T ₂ seconds is invalidated, it is possible to flexibly respond to the handwriting input, and T ₂ seconds elapse after the recognition is completed. If the pen touches the character input area D where the handwriting input is currently being performed later by mistake, the handwriting input is not re-recognized.
Therefore, it is possible to prevent the occurrence of erroneous recognition to confirm the handwriting input recognized character until it after a time T ₂ in advance.

Further, in S23, it is determined whether or not a handwritten character is to be input for the same item on the layout screen L. If the determination is YES, the process returns to S12 to return to the stroke based on the new handwritten input. The coordinate data of each stroke is obtained in the same manner as described above. If the determination in S23 is NO,
Returning to S3, the above-described processing such as printing is performed.

Here, when the print area H is touched with a pen (S3: YES, S4: NO, S6: NO, S9:
YES), the RO is displayed on the layout screen L in S20.
The company name and name displayed according to the display format based on the table 123A of M112 are perforated on the stamp face 30 of the stamp body 1 as it is. In this way, by matching the display state of the company name and the name with the print state, the user can create the same stamp as that confirmed on the layout screen L. It will not be done.

Next, when it is determined in S19 that the recognition has not been completed (S19: NO), that is, when the recognition is being performed, it is determined in subsequent S24 whether or not a retouching input has been performed. You. When no additional input has been performed (S2
If the rewriting is performed (S24: YES), the recognition process is interrupted in S25, and the process returns to S12 to start re-recognition. In the re-recognition process, the processes in S13 to S17 are naturally performed.

As described above, when the retouching input is performed during the recognition, the recognition process is temporarily stopped, and the character input is performed even when the handwriting of the retouching input exceeds the character input area D while the retouching input is enabled. Since the handwriting input is re-recognized by performing the enlargement process of the area D, the re-recognition is performed including the retouched input extending from the character input area D to the adjacent character input area E. Correction correction can be reliably and easily performed on characters that have already been input.

As described in detail above, in the stamp device P according to the present embodiment, it is determined that the end point of each stroke continuously exceeds the character input area D in the rightward or downward direction (S15: YES), When it is determined that the starting point of each stroke exists in the character input area D (S1
6: NO), the process of enlarging the range of the character input area D rightward and downward in S17 is performed based on the handwriting itself formed in the enlarged range. This is performed under the same conditions as in the case where the handwriting input is normally performed so as to fit within the character input area for one character. Thus, even when the handwriting of the handwriting input is formed beyond the character input area D, the character can be recognized with a good recognition rate.

The direction in which the handwriting protrudes from the handwriting input,
In addition, only the rightward direction and the downward direction of the character input area D are considered as the enlargement direction of the character input area D in S17. Thus, by taking into account the general tendency of the handwriting input by the user, a simple operation is possible. Only by performing the control process, it is possible to perform the character recognition of the handwriting protruding from the character input area D.

Further, in the enlarged character input area DE, the enlargement direction is restricted to the right and downward, and the enlargement range (amount) is set to a predetermined range ((X,
Y) = (1, 1) to (64, 64)), so that the amount of expansion of the character input area D is not unlimitedly enlarged, and the handwriting is generally input by hand at the time of handwriting input. The amount of enlargement of the character input area D is limited in consideration of the extent of protruding from the area D, so that enlargement processing of the character input area D can be easily performed.

Also, the handwritten input characters are displayed on the liquid crystal display 53 in a state in which the display format (attribute) stored in the table 123A of the ROM 112 is reflected in correspondence with the model screen touched by the pen. ,
The state of the stamp corresponding to the type of stamp to be created can be displayed on the liquid crystal display 5 without performing complicated format settings.
3 can be easily confirmed.

Further, by touching the print area H with a pen, the table 1 of the ROM 112 is displayed on the layout screen L.
The company name and name displayed according to the display format based on 23A are perforated directly on the stamp face 30 of the stamp body 1 so that the display state of the company name and name and the printing state match, and the user can display the layout screen L on the layout screen L. It is possible to create the same stamp as that confirmed. As a result, a stamp that does not meet the expectations of the user is not created.

If another retouching is performed during the time T ₂ seconds even after the recognition is completed in S19, the retouching is performed by enabling the retouching input and enabling the handwriting input again. since so as to invalidate the Categories input made after a lapse of ₂ seconds T, can be flexibly relative to the handwriting input, also errors after a lapse of T ₂ seconds after the recognition terminal currently when touched with the pen is in the character input area D doing handwriting input, rather than that the re-recognition of handwriting input is performed, therefore, after a time T ₂ is input by handwriting so far recognized by Thus, it is possible to prevent the occurrence of erroneous recognition by confirming the characters.

Further, if another stroke is not added during the time T ₂ seconds (S21: NO), at S22, the character input areas D to F displayed on the liquid crystal display 53 and each character are displayed. Since the characters displayed in the input areas D to F are erased, the user is notified that re-recognition by rewriting becomes impossible by erasing the character input area D and the characters. Can be.

Further, if a retouched input is performed during recognition, the recognition process is temporarily interrupted, and the rewritten input is enabled while the handwriting of the retouched input exceeds the character input area D. Of the character input area D
The re-recognition is performed including the retouching input that extends from the character input area E to the adjacent character input area E. Therefore, the retouching can be performed reliably and easily on the already input characters.

It should be noted that the present invention is not limited to the above-described embodiment, and it is needless to say that various improvements and modifications can be made without departing from the spirit of the present invention.

The present invention is also applicable to a tape printer.
