。所用の候補文字位置にカーソルがセットされた時点で
、入カキ−０１に上り正解データが入力される。A filled-in pattern (5) corresponding to the unreadable character (3) and candidate characters (6) are displayed. Next, the operator searches the candidate character group (6) for correct data determined from the displayed input character pattern (5). As a specific correct data input operation, each time the candidate character selection key is pressed, the cursor is shifted sequentially from the first candidate character position. When the cursor is set at the desired candidate character position, the input key 01 is pressed to input correct answer data.

作をしなければならず、操作が繁雑になる欠点があった
。The conventional OCR unreadable character correction method is configured as described above, so if there are a large number of candidate characters, it is necessary to perform key operations even for narrow openings in order to move the cursor to the desired candidate character position 1. However, there was a drawback that the operation was complicated.

全提供することを目的としている。This invention was made in order to eliminate the drawbacks of the conventional ones as described above, and by equipping a CRT device with a light pen mechanism, an operator can use a light pen to select correct data from a group of candidate characters. The aim is to provide all OCR devices that can input.

面上の対応する候補文字を正解データとして入力する。Next, the operation of this invention will be explained. The results read by OCR are displayed as shown by code (2) on the CRT screen (11). (6) is displayed.The number of candidate characters is arbitrary, and in order to increase the effect of this invention, it is preferable to display as many as 9 characters as possible.Next, the operator? Find the correct data judged from the glyph pattern (5).When the correct data is found, Light Ben Qll
'(, Apply to the above correct %% 7''-evening display location on the CRT.Next, the light ben control mechanism 02 detects where the light ben is placed on the (ERT screen, such as 'i'1.7). and informs the OCR device.Based on the information from the light control mechanism (I), the corresponding candidate character on the CRT screen is input as correct data to the OCR device.
なお、上記実施例で使用し７ｃ第２図の読取結果はカナ
文字を例にあげたが、ＯＣＲの読取対象文字としては、
数字、英字、記号等の他、漢字、ひらがな等も含まれる
。Note that the reading results shown in Figure 2 of the 7c used in the above embodiments use kana characters as an example, but the characters to be read by OCR are as follows:
In addition to numbers, alphabets, symbols, etc., it also includes kanji, hiragana, etc.
また、上記実施例では読取不能文字の記入字形パターン
（５）全参照するようにしたが、記入字形パターンを表

い。Further, in the above embodiment, all of the written character shape patterns (5) of unreadable characters are referred to, but the written characters of the read form may be directly referred to without displaying the written character shape patterns.
以上のように、この発明によれば、読取不能文字の正解
データ全１回の操作で簡単に入力できるので、複雑なＫ

縮される効果がある。特に漢字ＯＣＲの場合、その効果
は絶大である。As described above, according to the present invention, correct answer data for unreadable characters can be easily inputted in one operation.
/B operation is no longer necessary, which has the effect of shortening data modification operation time. Especially in the case of Kanji OCR, the effect is tremendous.
