Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a character reading device, and more particularly, to a character reading device that allows characters that are determined to be rejected as a result of reading to be corrected and inputted from a tablet.

The configuration of a conventional device of this type is shown in FIG.

In FIG. 1, characters written on paper 1 are scanned by scanning section 2, thereby reading the character pattern into pattern memory 3. The recognition unit 4 refers to the recognition dictionary 5, recognizes the character pattern stored in the pattern memory 3, and outputs the character code. If the recognition result is rejected, the character pattern stored in the pattern memory 3 is displayed on the screen of the display 7 in response to a command from the control unit 6. When the operator selects a character key from the keyboard 8 that corresponds to the displayed character pattern and presses it, the code of the character is sent to the control unit 6 and output as the recognition result of the input character pattern. In this case, if the type of characters to be read is alphabetical, numeric, kana, symbols, etc., and there are at most 20 types, even a non-specially trained operator can easily select and input the desired character key from the keyboard 8. Is possible.

However, when the character type to be read is kanji, at least five types are required, even if limited to characters necessary for a specific field. The drawback was that it was not easy to select. One way to eliminate this drawback is to use a kana key to input the sound, kun, or associated word of the kanji instead of pressing the key of the desired kanji, and to prepare the corresponding kanji in advance. A method is used in which a dictionary is selected from a dictionary and displayed on a display screen.

In this case, there are generally a plurality of kanji displayed, and the operator can select a desired kanji from among them and input the kanji by pointing at it with a light pen or inputting a number from a keyboard. However, this method requires that the operator accurately memorizes the sounds, precepts, and associated words of the kanji, which cannot be easily used without special training. There was a drawback. The present invention is characterized in that characters determined to be rejected as a result of reading can be corrected and inputted from a tablet, and the purpose is to realize a character reading device that can easily correct and input desired characters with fewer errors.

FIG. 2 shows an embodiment of the present invention, in which a tablet 9 is added to FIG. This system has two scanning units Bll for scanning characters.

In FIG. 2, when the recognition result of the character pattern in the pattern memory 3 is rejected, the operator inputs a character corresponding to the character pattern from the keyboard 8 or the tablet 9.

For characters that do not have a corresponding key on the keyboard 8, input is limited to the tablet 9. However, for characters that have a corresponding key on the keyboard 8, input is possible from either the keyboard 8 or the tablet 9. It's summery. The characters written on the tablet 9 are scanned by the scanning unit Bll and read into the pattern memory 3. If the recognition unit 4 recognizes that the character pattern in the pattern memory 3 is a certain character, the control unit 6 outputs a corresponding character code.
Furthermore, if the recognition result is rejected, the character is inputted again from the tablet 9. In this case, if the operator is limited to a specific person, it is possible to design the recognition dictionary 5 so that it is easy to correctly recognize the glyphs specific to the operator.
It is possible to sufficiently reduce the rejection rate of characters input from a tablet. In addition, although the case where the recognition part which reads the character written on the paper is used as the recognition part which reads the character inputted from the tablet above is used, this invention is not limited to this, and two recognition parts are provided, and the input of the character The recognition method may be changed depending on the medium.

As described above, according to the present invention, characters that have been determined to be rejected as a result of reading are corrected and input from a tablet by looking at the character pattern displayed on the display screen, and are input into a recognition dictionary in which character shapes unique to the operator are stored in advance. Because it reads and recognizes the characters input by the operator from the tablet, it is possible to accurately recognize the character shapes corrected by the operator from the tablet, and the rejection rate itself can be significantly reduced, making it possible to easily correct the desired characters with fewer errors. It has the advantage of being able to be input. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram of a conventional device of this type, and FIG. 2 is a block diagram of a device according to the present invention.

In the figure, 1 is paper, 2 is a scanning unit, 3 is a pattern memory, 4
is a recognition unit, 5 is a recognition dictionary, 6 is a control unit, 7 is a display, 8 is a keyboard, 9 is a tablet, 10 is a scanning unit All
is the scanning section B.

Claims (1)

[Claims] 1 A character reading device that reads characters written on paper, is equipped with a display for displaying read character patterns, a tablet for inputting corrected characters, and a recognition dictionary that stores operator-specific character shapes from the tablet in advance, and reads the reading results. A character reading device characterized in that a pattern of characters determined to be rejected is displayed on the screen of the display, and the rejected characters are corrected and input based on the character pattern written and input on the tablet.
