PURPOSE:To prevent the continuation of rejection and reading error by measuring the rejection ratio of one business form and switching a deciding parameter. CONSTITUTION:An area including a character pattern drawn in an input business form 1 is converted into a binary pattern by a photoelectric conversion part 2 and the binary pattern is supplied to a preprocessing part 3. The preprocessing part 3 segments only one character from the business form image expressed as the binary pattern and sends the segmented character to a buffer memory 4. The character pattern stored in the buffer memory 4 is processed by a feature extracting part 5 and the extracted characteristic variable is stored in a buffer memory 6. On the other hand, a category name and a characteristic variable for a previously fixed standard pattern are found out and stored in the dictionary 7. The contents stored in the buffer memory 6 are successively collated with the contents read out from the dictionary 7 and the collated result is sent to a discrimination part 9. The output of the deciding part 9 is sent to a post-processing part 10 and the insertion of the rejected character or the like is executed.
