Abstract

PURPOSE: To prevent the same character from being discriminated one or more times by counting a number that satisfies detection conditions and then by performing no discrimination even when a character pattern satisfying the detection conditions is detected corresponding to the number.
CONSTITUTION: Control part 16, when the frame of an observed pattern satisfies detection conditions, sets FF20 and also holds counters 21 and 22 ready for counting. However, counter 22 is incapable of counting bacause it is connected to terminal A' of FF20. Further, since control part 16 can not obtain any discrimination permission signal 27 from comparator 24 the pattern of this frame is not sent to the discrimination part. Next, when the observed frame does not satisfy the detection conditions, FF20 is cleared, counter 21 stops its counting operation and counter 22 counts frames that do not satisfy the condition. For example, since selector 23 selects the double value of the count value of counter 21, comparator 24 outputs signal 27 when the count value of counter 22 reaches the above-mentioned value. Therefore, when a pattern satisfying the conditions is obtained next, this is sent to the discrimination part.
