PURPOSE:To secure an immediate decision for the identification unable factor and thus to give the countermeasure for enhancement of the reading rate by deciding and also displaying the factor for identification incapability in course of identification for the characters read out. CONSTITUTION:The analog signal read out character 2 written on paper 1 is converted into two white and black signals through binary encoding part 4. These signals are identified by converting character 2 from initial state S0 to S7 at identification process part 5 and through extraction of the pattern characteristics and other methods. And the identification is decided impossible if the final state is those other than S7 and S9. On the other hand, the factor for identification incapability is decided as the slight change of the character shape at identification unable factor deciding part 6 in case the final state is S5 and S6. If the state is S1-S3 approximate to S0, a big change of the character shape and others are decided to display the decision result at display part 7. The process for writing, transfer or the like is carried out at character process part 8 via the identification code sent from process part 5.
