Abstract
A portable optical character reader which is designed to read optical characters, symbols and the like is provided with a unit for recognizing each character within the visual field, a recognition result storing unit for temporarily storing a recognition result, a recognition result comparing unit for comparing a recognition result newly obtained with the content of the recognition result storing unit, and a timer for measuring the time elapsed since a recognition result is obtained. In operation, when the same recognition result has been repeatedly obtained for a period of time which is longer than a predetermined time, this recognition result is output. Accordingly, no recognition result is output when the scanner is moved at excessively high speed, and therefore the operator can read characters by moving the scanner without any fear of erroneous recognition.
