2. Description of the Related Art Generally, since a pen input terminal can be used as if it were a normal writing operation, that is, as if using a pen and paper, it can be used for paper work such as insurance solicitation, stocktaking, and order placement. There is expected.

Further, it is expected that even a person who does not like the keyboard or who dislikes it can use it because the input operation is simple.

The data that can be processed can be numeric data or character data, and many data can be input at one time.

Conventionally, in this type of pen input terminal device, data input by handwriting is character-recognized by a recognition engine, and the character obtained as a result is displayed.

In this case, recognition is often performed by a method of collectively recognizing input characters after it is determined that the characters have been input or when the pen is separated from the digitizer for a certain period of time.

If there are unrecognized characters, those characters are displayed with a mark such as "?" To inform the operator.

The operator tries to input the unrecognized character again by handwriting for recognition again.

A pen input terminal device of this type is also known, for example, as shown in JP-A-58-105337.

In this patent, a handwritten sentence is read from an image input interface and displayed on an odd line on a display, and if there is an error in the read handwritten sentence on an even line, the handwritten sentence is corrected and displayed by handwriting or keyboard input. Is converted into a character code sentence. The input in this case is not a pen input, but a handwritten document is input by a character recognition device (OCR or the like).

[0011]

By the way, in the above-mentioned conventional pen input terminal device, the recognition rate of the recognition engine is 100.
Unrecognized characters often occur instead of%.

In addition, when characters are continuously input and recognized, unrecognizable characters are only displayed as marks or the like, so that there is a problem in forgetting what was written when rewriting later.

Also, in the above-mentioned Japanese Patent Laid-Open No. 58-105337, it takes time and labor to use a keyboard and a character recognition device, and the handwriting data and the recognition data are simply displayed on the same display screen. was there.

The present invention has been made in view of the above circumstances, and has an area for displaying the recognition data by switching the operation screen of the display and an area for storing the handwriting stroke when the data is manually input to the computer. An object of the present invention is to provide a pen input terminal device capable of correcting handwritten input data while forming an input sub-screen on a display and referring to handwritten data stored in a handwriting storage area.

[0015]

According to the present invention, as shown in principle in FIG. 1, an input unit (1) for inputting handwritten data.
And a recognition unit (2) for recognizing handwritten data input via the input unit (1) and converting it into a character code, and an input for displaying the input handwritten data and the converted and recognized character data. A display unit (3) which has a sub-screen and switches between the normal operation screen and the normal operation screen and corrects a character that cannot be recognized on the input sub-screen while referring to the handwritten data, and the display unit (3). ) And a display control unit (4) for controlling the operation of (1).

[0016]

In the present invention, the handwritten character data input through the input unit (1) is displayed in the handwriting stroke storage area of the input sub-screen of the display unit (3).

On the other hand, the input handwritten character data is recognized by the recognition section (2) and displayed in the recognition data display area of the input sub-screen of the display section (3).

The operator compares the handwritten character data on the input sub-screen with the recognition data, and if there is recognition data to be corrected, inputs the handwritten character again to correct the correction portion.

When the input operation is completed, the display of the display unit (3) is switched to the operation screen, and the character code of the recognized handwritten character is displayed there.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 2 is a perspective view showing the appearance of an embodiment of the present invention, FIG. 3 is a block diagram showing the configuration of the embodiment of FIG. 2, and FIG.
FIG. 3 is an explanatory diagram showing a flow of a control program for operating the embodiment of FIG. FIG. 5 is a flow chart showing the operation of the embodiment of FIG. 2, and FIGS. 6 to 9 are tables showing a customer address book for specifically explaining the embodiment of FIG.

In FIG. 2, the pen input terminal device is housed in a display screen 11 and normally a pen holder 12, and when a handwritten character is desired to be input, it is simply written on the display screen 11 to input an electromagnetic field. When the apparatus has an induction pen 13, the power switch 14 is turned on to operate the apparatus, so that power is supplied from the battery pack 15 to the apparatus.

The data input by the operator is taken out from the IC card slot 16.

The internal structure of this pen input terminal device is shown in FIG.
As shown in, the tablet 21 for inputting handwritten characters
And a tablet control unit 26 for controlling this, a display unit 23 for displaying handwritten characters input from the tablet 21, a display control unit 25 for controlling the display unit 23, and handwritten character data input from the tablet 21. And an input handwritten data recognition unit 22 that outputs character data to the display 23. The display unit 23 has an operation screen for normal display and an input sub-screen used for inputting handwritten characters. However, the display control unit 25 can switch the display.

The input sub-screen has a recognition data display area for displaying the recognition result and a handwriting stroke storage area for displaying the input handwritten characters as they are.

By switching to such an input-only sub-screen, it is not necessary to take an extra area on the operation screen for normal use.

Further, the apparatus of the present invention is provided with a ROM 27 which stores a processing procedure program such as an input / output control program, a BIOS and a system, and a RAM 28 as a working memory which stores this program.

The processing procedure program stored in the ROM 27 and the RAM 28, the contents of this program and the flow of processing are as shown in FIG.

In FIG. 4, reference numeral 31 designates an input detection procedure.
2 is a processing determination procedure for determining processing based on input data,
Reference numeral 33 shows a handwriting stroke copy processing procedure, 34 shows a handwritten character recognition procedure, 35 shows switching processing between the operation screen and the input sub-screen, and 36 shows display processing for displaying the operation screen and the input sub-screen. It is a program.

The operation of this embodiment configured as described above will be described with reference to FIGS. 5 and 6 to 9.

In FIG. 5, an operation screen is displayed on the display unit 23 in step S1.

Next, in step S2, it is determined whether or not to switch to the input sub-screen. If YES, the input sub-screen is displayed in step S3, and if NO, the process returns to step S1.

Furthermore, it is determined in step S4 whether or not to switch to the operation screen. If YES, the characters recognized and converted in step S5 are displayed on the operation screen, and step S1
Return to.

If NO, handwritten characters are input through the tablet unit 21 in step S6.

Subsequently, in step S7, it is determined whether the input is for correction. If the completion flag is on, it is determined that the input is for correction, and step S8 is not performed and the process proceeds to step S9.

If YES, in step S8, the handwritten character is copied and displayed in the handwriting stroke storage area on the sub input screen.

This process is continued until it is determined that the input is completed.

If NO, it is determined in step S9 whether or not the handwritten character input is completed. If YES, the handwritten character input by the recognition unit (recognition engine) 22 is converted in step S10 and the input sub-character is converted. Display the converted characters in the recognition data display area of the screen.

If NO, the process returns to step S6 to continue inputting handwritten characters.

In this way, the data after recognition of the handwritten characters is displayed in the recognition data display area of the input sub-screen, while the handwritten characters are displayed as they are in the handwriting stroke storage area.

When there is a character that cannot be recognized, the operator inputs the character while looking at the handwritten character displayed in the handwriting stroke storage area. When the input character is correctly recognized, the character is replaced and the correct recognition data is displayed. That is, "?" Is converted like a correct character.

Since the handwritten character input for correction has already been input and the handwritten character has already been displayed in the handwriting stroke storage area, it is necessary not to display the copy.

The reason is that if the copy display is made, the handwritten character for correction is displayed on the first input handwritten character, and the handwritten stroke storage area becomes very difficult to see. Therefore, the input completion flag is referred to, and when the input completion flag is on, the copy display of the input character is not performed.

As described above, the correction is repeated until the input handwritten character is correctly recognized, and the input is completed.

After the input is completed, the input data is displayed on the operation screen when the screen is switched to the operation screen.

FIGS. 6 to 9 show the above operation in a concrete example of inputting the customer name, address and telephone number of the customer address book.

In FIG. 6, when "input" on the screen 11 is pointed by the guide pen 13, as shown in FIG. 7, an input sub-screen consisting of an upper recognition data display area and a lower handwriting stroke storage area is displayed. To be done. When handwritten characters are entered in the recognition data display area in the upper part of this input sub-screen, the handwritten characters are moved (copied) and displayed in the lower handwriting stroke storage area as they are, and the recognition result is displayed in the upper recognition data display area. It

In this way, when a character is written in the upper recognition data display area, it is recognized that the character that cannot be recognized is "?".
Is displayed. In the lower handwriting stroke storage area, handwritten characters are displayed as they are, and can be referred to when correcting and re-inputting unrecognized characters.

Further, as shown in FIG. 8, when the handwritten character is correctly recognized, "completion" on the screen is pointed to. As a result, the original customer address book is displayed as shown in FIG. 9, and the recognition result is displayed correctly.
