发明名称 Numerical expression recognizing apparatus.
摘要 <p>There is provided a numerical expression recognizing apparatus for recognizing a handwritten numerical expression and outputting as a code train. This apparatus comprises: a coordinates input apparatus (11, 12) for inputting a numerical expression consisting of characters including numerals and signs by coordinates; a recognition circuit (21, 22) for recognizing the characters including the numerals and signs and constructing the numerical expression on the basis of a set of the coordinates which were input by the coordinates input apparatus; and an output control circuit (24) for outputting the pattern of the numerical expression constructed by the characters on the basis of the coordinates which were input by the coordinates input apparatus and the characters recognized by the recognition circuit. The pattern of the numerical expression is displayed by a liquid crystal display (13). The recognition circuit (22) has a converter to convert the characters constructing the numerical expression which were input by the coordinates input apparatus into the code information. With this apparatus, a numerical expression including fraction, power, square root, or the like can be directly easily input in accordance with the expressing method which is ordinarily used in the mathematics in a manner similar to the handwriting.</p>
