<p>PURPOSE:To perform the processing of a character equation with a simple constitution, by comparing the character equation to be fed with the stored character equation and reading the stored correspondence equation when the coincidence is obtained in the above-mentioned comparison. CONSTITUTION:An input circuit 3 delivers an input data corresponding to a key code given from a keyboard 1 to supply it to a data memory 5 and at the same time feeds the integral symbol signal to a converting circuit 6 and a control circuit 4. The circuit 6 supplies the data fed from the memory 5 to a character memoty 7 as it is as long as the data is a character equation. The data of the memoty 7 is fed to a character equation processing circuit 9. The circuit 9 contains a dictionary memory to store the character equation and the corresponding character equation obtained by integrating said character equation. Then these character equations are compared with the character equation fed from the memory 7 through a comparator. When the coincidence is obtained from the comparison, the character equation corresponding to the relevant character equation is read out of the dictionary memory to be offered to an operation.</p> |
